A comment made by Hinata during dinner with her family had caused Naruto to try having clones pretend to be her while examining technology. Those clones sucked at examining seals, which wasn't a surprise, and trivially figured out a number of things that baffled him even after processing the memories. Adding in most of the technology division, plus Hanabi for good measure, had him coming up with an idea he wouldn't have considered otherwise.
Sending an area search into the Tome to see how it worked.
Even with the technology division clones he couldn't understand ninety percent of what was in there, but one thing he had figured out was that there were spell processors. Reproducing those, even if his ended up being a bit larger, meant that he could have computers cast spells. Grabbing the math for all the spells they had out of the Tome had been easy enough, and he felt that was the last couple of pieces needed for his version of the Land of the Sky's flying city. Complete with a 'held from completing' teleportation spell as a last-resort safety. Cutting power to the city would, if he'd designed that correctly, release that spell and teleport the whole thing back to the 'drydock' he'd built to construct the city in the first place.
Flight systems that took way too much power, redundant castings of the flight spell modified for computer control, and the emergency last resort teleportation spell felt like enough safeties for the city being flying. Now he just had to build the rest of it such that it would be difficult to fall off, among other things. Maybe add in an airship station under it as well, since they didn't usually fly too high?
He also needed to ensure that he had everything needed for chunin exams included, of course, and determine how to get people onto and off of the thing. The airship station would be an option, but adding in ways to launch flying machines was probably not a bad idea either, and targeting moving objects with teleport seals was actually a bit tricky. Those tied to the Uzushio summoning contract could just target the flying city's arrival stone, of course, but visitors...
Konan frowned as she read the scrolls she'd been provided. How in the world had Naruto figured out even a fraction of this? Turning shadow clones into chakra-created clones made out of paper, adding ink into the mix to make them paperwork, and then forming that ink into explosive notes...
Well, okay, once you had paper with ink the explosive notes side was kind of obvious to work on. Except he'd needed different ink for that, so 'paperwork with explosive seals on the back' was two different inks. How did you keep chakra-created ink from being chakra-conductive for the normal printing?
"The first couple of groups have crossed into the outer forest," Nagato called from where he was monitoring the cameras. "Including that group of chunin that are hoping for a promotion."
"They the only ones sticking together?" she called back.
"So far."
It was honestly unknown how the evaluations would go on that front. Working as a team didn't show individual skills but striking out on your own into an entirely unknown environment was frankly stupid. Neither of the two of them had been involved in this kind of evaluation for Uzushio either, so they didn't have the experience needed to guess. Really, most of their reason for monitoring was in case they needed to step in, and most of that was going to be 'summon idiots out of the forest'.
The group of chunin looking for promotion were the only ones she expected would be willing to admit defeat and summon themselves to a stone to escape.
She'd have to join Nagato at the cameras once teams started reaching the really dangerous areas, but for now she was determined to prove that she was still the master of paper-based techniques.
"Naruto's doing something big again," Ino noted as she reviewed some infiltration training reports, grimacing as she wondered how this team had ever thought that would work.
"Yep," Hinata said as she worked with her clones to make copies of things.
"Do the infiltration books cover not trying to impersonate someone at a party when the person you're impersonating is in attendance?"
"...they do, including ignoring that intentionally if you're good enough to make people think the real person is the fake one and the mission parameters allow it."
"Which just makes this team's performance worse."
"So, have you spotted anything that would tell us what Naruto's doing this time?"
"I assume it's related to the chunin exams because none of the prep is happening anywhere anyone can see it."
"That is a bit of an obvious sign, yes. He's making sure he has everything ready, double-checking details as he runs into implementation problems, but not anywhere anyone can check the work themselves."
"Running bets are that he's making or transforming yet another island."
"He has been doing that a lot recently, but I get the feeling he's going for something more impressive this time."
"Yeah, but there's now a 'chunin exam island' summoning stone in the system that is locked down to just him for 'construction safety' purposes."
"I missed that. You run into it while checking permissions yesterday?"
"Yep. Didn't find the permissions issue they thought was there though."
Hinata blinked at that, looking up from the paperwork. "Oh? Then why can one of the genin summon others when the rest can't?"
Ino shrugged. "They're field medic certified and tested to have enough chakra to handle medical evacs."
"Ah, that nicely explains their limited ability to summon others."
"We're just spoiled because we're in the 'nearly unlimited' categories. Though I don't know why I was doing those checks instead of someone from the technology division."
"Because yesterday we were attempting to work with the seals division to figure out Naruto's insanity. Again."
Oh, right. Ino was doing her best to stay far away from that mess.
"Good morning," Naruto said to the gathered shinobi. "I decided to hand out this particular stack of missions in a...unique way." The group shared looks, and then he picked up the top folder. "These are all strikingly similar missions in the abstract. A well-placed noble that is doing heinous things in secret, the latter already confirmed. Clients who cannot be connected to the removal of said nobles want them gone, ideally such that nobody can tell that it was enemy action without having access to the reports on how it was managed."
He could see that they were now thinking, but the individuals and team leaders were all nodding. After letting that sink in for a minute he continued. "That said, in many ways this is looking to be too easy. So I decided to extend things a little bit. One individual or team per target, and the analysts will be examining anonymized after-action reports to judge who did the best job of meeting the mission parameters. Full copies of my personal recon notes and maps are provided in the folders here. I will allow you all to decide amongst yourselves which individual or team takes each specific mission. Whichever one remains I will personally handle."
The folder he was holding was dropped back on the stack and his clone turned on the screen behind him. Mission numbers were grouped into general target crimes on the screen. Those killing entire families to expand their power base were on the far right. Slave trafficking, split into 'general' and 'sex', were next. Then there were those that killed the parents and enslaved the kids, again split into 'general' and 'sex' slavery. Finally there were three that were working on all of the above to entire small villages.
Only judicious use of cut-outs and middlemen kept most of this from being trivially tracked back to each noble, and unfortunately the evidence linking back to them wouldn't hold up in their individual communities. Justifying killing them was thus difficult for those who wanted the problems solved, hence the missions to get rid of them without anyone knowing it had been intentional. In fact, for most of the nobles they'd be risking international incidents through taking the missions at all if not for the missions coming from Daimyo...and the Tsuchikage.
It took an hour to get missions distributed, leaving Naruto with one of the trickier ones. A particularly paranoid noble surrounded by repeatedly-verified trusted staff, half of which had to go with the noble, but where the noble's daughter needed to both survive and not be seen as likely at fault despite normally being kept in his immediate presence. A nice distraction from the more complicated work he'd been doing.
Nagato had to admit that he was surprised. The team of chunin had, as predicted, made it through to the tower essentially unharmed. Running very low on supplies and not having camped properly, but they'd made it through. Four demoted jounin had also made it through though, two solo and two through teaming up with one another. They'd also lost three idiots, one had realized they were in over their heads and removed themselves, and the rest had to be forcibly removed and weren't happy about it.
They were alive to not be happy about it, at least, and being shown the footage from one of the three that was lost had them stop grumbling as much. Or at least not openly grumbling, which was good enough for him.
"So the team of chunin is getting 'individual skill tests' to ensure that they aren't too reliant on each other," he finally said as he reviewed things. "With the expectation that they'll remain chunin, but given how much trouble they had as a group it's likely they won't argue it. The two that made it through on their own have earned provisional jounin status pending retesting of the required items they failed on the first time, and the pair that made it through together seem to have only done well enough to make special jounin due to over-reliance on specialties instead of having sufficient general skills."
"A far better result than expected," Konan agreed.
"And you have failed to get paperwork shadow clones working."
"...it's a lot harder than it seems like it should be. I swear that wood release is being used to help make the paper."
"Well, that honestly wouldn't surprise me. You could attempt that on bloodline island?"
It was obvious that she'd not actually considered that, based on the look on her face. "I...am not used to 'sign up to earn a bloodline' being an option."
"Can't blame you for that. It's basically unheard of. But we're now officially done with Amegakure integration and are going to be encouraged to move onto other things to ensure that the shinobi don't rely too much on us in the new system."
She nodded, and he idly wondered if he should go for a couple of bloodlines himself before going into other things. There were some traditional Uzumaki bloodlines in the mix and having one or two of those instead of the false rinnegan felt like it would be properly honoring his heritage.
Kiba had thought he was grabbing one of the tricky missions for his team, and under normal circumstances it would've been quite difficult to get the targets and not the nobleman's whole family. But they'd arrived just in time to find out that their three explicit targets were about to leave together. His team was excellent at tracking without being spotted and had followed the three to a hidden harbor where they met up with a team of drug runners...and a ship currently devoid of slaves with plans to leave as a group before that was changed.
'Stumbling' on the operation as though a group of lost civilians had been trivial, and they'd been taken aboard the ship to be sold as slaves elsewhere. Once at sea it had been trivial to slip their chains, direct the ship further out than it was originally intending to go, and sink it with all hands still aboard. Their targets would simply vanish, and nobody would know when they'd died either.
The whole plan would've been horrible to pull off without the summoning contract to get back to Uzushio with, but luckily they had that.
Sasuke had wanted to grab one of the seemingly-tricky missions, but realistically he had to stick with what he thought his team could manage. He'd still gone for one that looked like it would require some actual effort though. A noble's daughter was abducting teenagers to 'play with' for a few weeks at a time, then selling them off to fund the mercenaries that she used to obtain more playthings. Killing her without getting the attention of her parents or brother, and ideally while freeing her current 'playthings', was definitely a challenge.
...or it should've been, anyway. Totan had gotten tired of the planning, gone off on his own, and approached the mercenaries she used for obtaining and selling her playthings. A down payment on them obtaining a slave that just happened to match her description, supposedly to replace one 'accidentally crippled', had gotten the mercenaries to grab her when she arrived to swap her current playthings for newly-acquired ones. That had nicely negated all the problems with getting her away from her family...but had necessitated following the group to a nearby town with a sheltered dock.
There was obviously an expectation that they'd be able to dump everyone other than her on someone coming by ship, in exchange for some drugs. Damaging a couple of locks when the mercenaries weren't paying attention allowed the teenagers to get out of the cages with minimal prompting, and nine of the mercenary group plus their target had ended up dead before intervention had been needed to keep the abducted teenagers from being killed. Minor illusions to convince them to run off and the mercenaries to not chase after them, mostly, while stealing back the 'down payment' previously made.
"This is annoying," Sasuke grumbled after throwing a genjutsu on a couple of the mercenaries to get them to violently 'blame' the others.
"It worked," Totan defended.
"Except we can't just kill them directly because that would make it obvious that shinobi were involved, meaning we're babysitting illusions and manipulations until the town guard shows up to find them fighting amongst themselves."
"Easier than fighting them."
"And you got incredibly lucky that the ship is running late, because otherwise they'd likely have had backup or we'd be trying to rescue people from a ship."
Totan had no retort for that one.
Obito grumbled as looked over the new academy security course. His go-to would've been forcing his way through or abusing intangibility to pass through obstacles, but he couldn't do either of those here. Actually, he couldn't do the intangible thing at all since having his mangekyo removed. He also hated getting through most locks, but he'd been shamed into learning how to without damaging them.
...pin tumbler locks were annoying. The whole 'stick chakra between the two pins in each stack' trick was also incredibly fiddly and he needed enough focus that he needed to use a little fake key thing for spinning the actual cylinder instead of using his chakra or something like a fingernail. Not that he kept his fingernails long enough for that purpose.
"How are things looking?" Kataru asked.
"I think all the basics they need to worry about bypassing are in place," Obito answered.
"You're quite good at setting them up even if they give you trouble afterwards."
"This is simple. A minimum of security seals, just enough to keep them from slipping through in ways they're not being tested on."
"Heard they had you secure a building for chunin to work their way into last week."
"They let me put traps into that one."
"Think you could keep out an Uzumaki?"
That had Obito scoffing at the man. "Not one like the Uzukage. Or anyone he's probably ever taught, and probably not anyone they taught. I did get some practice keeping more normal S-Class shinobi out of a few places though."
"...really?"
"Yes. Had to balance the complexity of legitimate access with their likelihood of blowing the place up in frustration though."
That he'd been doing it without revealing himself had been the honestly amusing part. Showing displeasure with Akatsuki members through locking up their preferred snacks, or Sasori's supply closet, had probably been a bit petty at the time, admittedly.
Ino watched from afar as the trusted servant her clone was controlling served drinks. Killing only the noblewoman, the runner she used for her illegal business, and business partners was quite difficult. Her personal servants were a gray area that had been permitted to die if their inclusion would make things more believable, but the rest of the staff and family had to be left both alive and blameless.
Learning how to be that servant had been Ino's choice, followed by using said servant to collect items from the area and make a crude poison. The remnants of doing so were in the servant's belongings, ready to be found by investigators, and the poison itself had been added to the refreshments offered at tonight's illegal business meeting. Of course, the servant was expected to prove that things weren't poisoned by consuming a little of everything herself, making poisoning the others an apparent suicide in the process.
She knew her clone would be using subtle medical chakra manipulation to keep the poison from causing enough damage to dispel the clone through transferred damage, though it wouldn't be much longer before the others started to succumb. Finishing the others off with sloppy use of a kitchen knife would follow, and then the poison would be allowed to finish the servant off before she could get to the hidden but improperly prepared antidote.
All the evidence should show that the noblewoman had been keeping this a secret from her family, and it was unlikely that any prodding would be needed to ensure that the deaths were blamed on the servant having a change of heart regarding the illegal business dealings. A planted 'note' from the noblewoman about checking the sale value of her personal servants to get new ones due to not knowing if they could actually be trusted would help explain why the servant had gone this route as well.
Once all of that was confirmed she could head back home, because this had been an annoyingly tedious mission to do 'right'.
Hinata nodded as the bridge her target was crossing collapsed, the obvious fault of bandits that had been charging tolls for use of the bridge. She had clones in the form of animals in the ravine in case there were survivors that needed to perish before help could reach them, but it quickly became obvious that they weren't needed.
Getting the noble to divert to this weaker and lesser-used bridge had been a simple matter of spreading a completely accurate rumor that the more commonly used bridge was being used by drug traffickers. The noble wasn't one, but also didn't want any record of traveling through the area to be entered into the logs of the samurai doing checks of travelers. Three drug runs had been intercepted by the samurai as well, which had just made them more zealous about the whole posting.
The bandits had already been here and known about too, but were considered low priority because the local leaders wanted to promote the use of the better quality bridge anyway. One of the two local hidden villages might be sent out to take care of the bandits now that they'd caused the death of a noble, if only thanks to the couple of surviving guards that had gotten off the bridge in time ensuring that their deceased employer was avenged. Maybe, if the noble's kids cared enough to agree to the expenditure.
All indications were that they did not get along with their father though, and their mother had been out of the picture for a few years now.
She cleaned up a few details that might point to something other than the bandits having not been as careful as they should've been with the bridge, as originally they hadn't actually put their 'toll sign' through one of the buried supports. Moving it a couple centimeters over hadn't been noticed though, but after doing so she'd spotted a couple of minor inconsistencies that she could now correct before anyone else noticed them.
Onoki looked over the reports in front of him, covering various sightings and encounters of Uzushio shinobi. "So we now have five broad types of Uzushio shinobi."
Akatsuchi blinked a couple of times. "Five?"
"I'm including their special forces."
"Yes, but that's still only four."
"From an interaction point of view, those wearing both the Uzushio and Konoha forehead protectors have to be split based on which is currently being worn as their primary as that indicates which village they're officially working for at the time."
"Oh."
"But now we've also got those wearing the modified crossed out Amegakure forehead protectors. Very obviously set up to no longer be a full protector and worn seemingly more as an honor item."
"We already knew that they absorbed Amegakure though."
"Yes, but until their training normalizes things out we can make general assumptions. Most former Amegakure shinobi are going to take time to not be overspecialized in their techniques, so they'll likely still be able to be blindsided if you can spot a way around them. I can't see Uzushio allowing that to continue long-term, but having them advertising their former association like that provides useful information."
"Which means we can't trust it because if we came to that conclusion then they would've too and will probably be having those who don't have that weakness wearing it as well."
Onoki was about to respond when he realized that was, unfortunately, correct. Missing that made him feel like a fool too. "Dammit."
"And thinking about it, I think there's an extra category."
"What would that be?"
"Do you want to bet that the escort teams seen without forehead protectors at all aren't Uzushio, even if they were operating in the Land of Fire?"
That also made far too much sense. "It's weird having a village that doesn't care about advertising themselves on missions."
"They seem to do their advertising everywhere but missions. The only ones broadcasting chunin exams for those not present to watch in real-time, those telephone booths all throughout the Land of Fire..."
"Ugh. The Daimyo is still annoyed that we can't get our own telephone system, even if Uzushio could probably listen in on all calls made with the thing."
Naruto looked over the group of teams that had come back, and two of them were looking annoyed. "As some of you know, three missions were officially failures. Mine was one of them as during our previous meeting my target was running into and being killed by bandits. I did not attempt to play that off as intentional to take out the target because pretending you can arrange things that you didn't arrange is bad if anyone happens to figure that out. Another team was interrupted by enemy shinobi and pulled out before they were spotted and the last team could not find their target who has apparently not been seen since before our previous meeting. Two teams were further disqualified from the competition because they allowed innocents not on the acceptable targets list to come to harm."
There were nods at that, and the representative of the analysts handed him an envelope. He didn't open it immediately, looking over the group. "Obviously, full reports will be made available for those who had an opportunity to complete your missions. In addition, I was told that there were three different cases of one team accidentally making another team's job easier, and two cases of one team accidentally hindering another team. Whether those end up in your reports or not will be up to the analysts."
He let them process that while he carefully opened the envelope and unfolded the paper within. As he finished reading the room went silent. "The winner of the bonus payment is Team Kada for managing all of their directives through ensuring a single letter was 'accidentally' delivered to a neighbor due to being lightly stuck to the back of another item."
Heads swiveled to Korima Kada, who shrugged. "We were considering something more elaborate, but a quick check of mail to be delivered presented an opportunity and we'd have been foolish to not run with it."
"Those with 'suitably impressive' performances will also be getting smaller bonus payments," Naruto added before anyone could grumble too loudly. "You'll need to check your full reports to find out if you qualified." There were still some grumbles, but then he looked around the room. "That said, anyone who wants to see the initial reveal of chunin exam island is welcome to join the audience this afternoon."
Sakura looked around the 'room' they were in, likely hanging underneath an airship. Covered windows faced in one direction, likely pointing at the island to be revealed, but privacy seals were even stopping the Hyuga present from peeking before the actual reveal. Two screens also showed a countdown, and occasional broadcast messages came over the audio feed.
"Evacuation processors charged, beginning casting sequence."
What those broadcast messages meant was an entirely different question. The first few she'd heard had all been power and powering up various systems related, at least.
"I like the idea of dedicated areas for exams," Karin commented. "It negates entire categories of security issues for the main village."
"Still creates some headaches if they have to pass through Uzu to reach it," Sasuke retorted. "I don't think we're close to the mainland right now."
"Multipurpose processor bank A charged. Preparing casting sequence."
"I do wonder what insanity Naruto came up with this time," Sakura said as she looked around at the others again. "Because I see several seal and technology division members here and they all look baffled at the broadcast messages."
"Who knows," Sasuke replied. "Something crazy and impressive, but that's kind of what he does."
"True."
"Multipurpose processor bank B charged. Preparing casting sequence."
They lapsed into a comfortable silence for a few minutes, only broken by the arrival of a couple more people and the announcement that banks 'C', 'D', and 'E' were also charged. Then the countdown on the screens ran down and an image of Naruto appeared instead.
"Good afternoon everyone," he said over the audio feed. There was obviously a slight syncing issue there, the audio and video being maybe half a second off from each other. Probably because they were two entirely different systems in this case, the audio feed being linked to the 'broadcast back to Uzushio' feeds instead of the ones in the various observation rooms. "I could go on for several minutes about what's going on and why, but I'm reasonably certain that would increase people's annoyance with me and I don't think there are any last-minute problems requiring a delay to solve."
With that, the coverings on the windows pulled up and out of the way, revealing that they were on one of several airships circling a hexagonal island. The middle was dominated by a large forest, with a larger than usual Uzushio tower in the very center. Each 'point' on the hexagon contained what looked like a settlement with their own towers, and five of them were very obviously elementally-themed. Fire looked like a small volcano, wind like a series of canyons in a bit of a sandstorm, lightning seemed to be a mountain peak surrounded by storms, earth was an expanse of rocky terrain, and water sat on a smaller island in the middle of a lake. The last point, sitting between the water and fire points, was the largest and very obviously contained an arena for the final stage of the exams. Presumably it also contained accommodations for the visitors.
Around the central forest was an obvious 'get between the six points of the hexagon' ring that also contained gates for accessing the forest. Leading off of that were paths into the 'edge' areas that contained obvious training grounds and what were probably various semi-permanent testing areas. Walls, fences, and gates visible even from the air would presumably allow for shifting which areas were accessible and which weren't. The perimeter of the island also contained an impressive wall, though why you'd need one in this case wasn't really clear. Beyond discouraging boats from docking, anyway, as there obviously wasn't any provision for getting onto the island from the water.
"Some of what you can't see here is that there are underground facilities and routes spread throughout the island," Naruto explained. "Many of which will be available to the participants during the exams, depending on the current stage and goals. The wind area also doesn't always have sand in the mix, but it certainly makes it easier to see things blowing around. But you've not seen anything yet. The evacuation system is at one hundred percent and holding steady, so here we go!"
"...this is already impressive," Sasuke said, frowning. "What else has he done?"
Flashing lights suddenly lit up along the entire outer wall of the island and the airships all started to back off. The voice that had been doing the earlier announcements then came back.
"Multipurpose processor bank A, casting atmospheric shields." A glow appeared over the island, anchoring back to the walls, then faded. "Casting complete. Multipurpose processor bank B, casting atmospheric shields." A second glow appeared and faded. "Casting complete. Multipurpose processor banks C, D, and E casting motive arrays." This time the island itself seemed to glow for a moment, before fading. "Casting complete. Motive array self-tests returning green. Airspace is sufficiently clear. Engage!"
Sakura could only stare as the entire island started to lift out of the water, the surrounding ocean rushing in to fill the void it was leaving behind. Nets unfolded from the walls, obviously a last resort option for catching someone falling off, as the island ignored the laws of physics and rose into the air. It wasn't long before the underside of the island was visible, the walls continuing straight down with a ring of windows before things sloped inwards. Obvious large doors were set into the angled section before another ring of windows and then a flat bottom. The center of the latter suddenly dropped, revealing an airship station. Several of the doors suddenly opened as well, revealing that they were likely takeoff and landing spots for the faster flying machines.
"The upper ring of windows is three quarters hotel rooms," Naruto explained. "I figured that this could make an interesting 'destination' for nobles that want an experience even when we aren't holding exams. Whether or not we get permission to fly over any given country is going to be interesting to see though, given that tourism would likely increase just to get a look at the island itself, but for this exam session we'll be parking in the air south of Uzushio."
"He's lost all hope of figuring out what 'normal' is," Karin declared.
Nobody attempted to argue that point.
"WHAT DO YOU MEAN, YOU JUST PRETENDED TO BE ME AND THE TECHNOLOGY DIVISION TO FIGURE OUT HOW THINGS WORKED?"
