There was no point in confusing things now.
"I'll go down first, follow after and hold position at the entrance while I divine the surroundings," Ling Qi said. A small wisp silver light spun out from her palm, descending into the tunnel, it went down quite far.
Xia Lin gave a silent nod, faint lines of light blooming along the joints of her armor, barely visible under the scouts cloak she wore.
Her wisp descended far enough to make out the floor, it was conspicuously damp, another sign of poor repair. There were signs of security formations spiralling down the shaft, but they too were worn by water damage and showed no signs of activation.
<Sixiang, can you follow my wisps out, give me another set of eyes on the breeze?> she asked silently.
"Can do," Sixiang affirmed.
<Zhengui, prepare to stay small if I bring you out, I doubt there's much space. Hanyi just stay ready,> Ling Qi continued absently. The bottom looked safe.
She descended in silence, her other diving wisps circling her head. Landing in a crouch, she sent them spiralling out into the chamber at the bottom. It was small, only a few meters across, but three tunnels reached out. Small and cramped they were roughly carved shaped by the quick excavation of an earth technique most likely.
As the wisps spread out sending her information from down the tunnels, Xia Lin dropped down beside her, making only a slight thump despite all of her armor. She held her halberd in a low guard position, eyes flicking from one tunnel to the next.
There were spirits down here as well, Ling Qi thought as images from all of her wisps fed in at once. Little creatures of mud and river water crouching in corners and floating in stagnant puddles. More of the little knot-hole eyed creatures clung to damp roots that poked through the ceiling as well, and down the third tunnel, where stone had caved in fungal creatures clung to muddy stones, supping on a rotting log.
Ling Qi gestured sharply to the leftmost path. "Dead-end, tunnel collapse," she said quietly.
"And the other paths?" Xia Lin asked quietly, smoothly orienting toward the other tunnels.
Ling Qi frowned. Down the middle path there were a few rooms, filled with the rotted remains of furniture, it seemed like a small barracks or waystop, beds, a few racks of weapons, there was a small chest that radiated the energies of spirit stones. Something to check later. On the right was a room with three equally spaced pools of clear clean water, over which hung a contraption of brass and mirrors, now tarnished and cracked. She wasn't expert enough to say for sure, but it looked like some kind of clairvoyance set up.
"Disused scrying chamber on the left, barracks in the middle," Ling Qi said.
"Unsurprising," Xia Lin muttered. "We are fortunate that the site seems abandoned. The Hui were fiendish in their trapmaking."
Ling Qi eyed the many intricate formations carved subtly into the walls around them. Xia Lin wasn't wrong. However she had to say comparing the style of the arrays to Xuan Shi's or the Sect work she had studied, it seemed terribly fragile. Too much complexity, relying on cascading energies that would no doubt be powerful, but which had broken so easily without maintenance.
"Do you have any experience with this sort of thing," Ling Qi asked.
"Indirectly," Xia Lin replied. "My elders in the regiment have passed down their experiences rooting out the many boltholes of the Hui. I myself have only experience in removing proscribed cults from abandoned locations."
Ling Qi pursed her lips. She had never been deeply involved in the temples or cults, she was pretty sure the Empire took a light hand with them though, so to be proscribed... "That must have been unpleasant."
Xia Lin simply nodded, her lips set in a thin line.
Ling Qi jerked her head toward the scrying room tunnel, sending a silent whisper to Sixiang to watch their back. "Anything I should be aware of?"
"Hidden entrances, dream labyrinths, blood locks," Xia Lin said quietly. "Be wary of using your insubstantial movement to pass through things, the Hui were more paranoid of their own than enemies."
Of course they were, Ling Qi thought grumpily. The web of energy for the formations above ran deep through the stone, too deep to be easily disrupted. She did not have any arts good for large scale destruction. Even Call to Ending was not suited for attacking earth and stone that did not have flesh beneath. "Do you have any formation breaking methods?" Ling Qi asked as they entered the hall.
"My blade pierces and shatters the works and lies of the wicked," Xia Lin replied confidently. "Her grace made it with that purpose in mind."
Ling Qi glanced over toward the halberd head, pointing out in front of them, and watched the faint buzz of radiant qi that hummed along the grain of the metal. It brought to mind last year, when Meizhen had brought out a tool from her clan vaults to shatter her enemy, Yan Renshu's defenses.
The skein of energies in Xia Lin's weapon were so much more refined and sharp than the obsolete siege rod Meizhen had used. "...Let me try my hand at any obstacles first. If there is anyone left, we don't want to alert them. I'll have Sixiang signal you if I want you to strike."
Xia Lin nodded her assent. There were no more words as they traversed the tunnel and entered the clairvoyance chamber. It was as old and abandoned as the rest, but entering herself, Ling Qi noted details that her wisps had missed. The contraption above was corroded and hung with webs, and the shadowed ceiling teemed with normally sized spiders, they scurried hissing from their presence as they entered and lurked between brass gears and fittings, withered spirits, half drained, twitched feebly in their webs.
Ling Qi crouched down by the closest of the water pools. It was rounded, and lined with fired clay tiles. It was shaped and sized for use with divination arts not much different than hers. If she had to guess the tarnished mirrors hanging above were some kind of focus for a more advanced form. Ling Qi pondered whether she could make use of it for anything, or if it would be better just to break it.
"There is an entrance here," Xia Lin said quietly, making her look up.
She followed the girls pointed finger to a section of wall to their right. Squinting for a moment, she saw the shimmer of illusory qi. Stone swam before her eyes and became a sheet of webbing covering a narrow gap. With a thought, she sent a wisp flying toward it, only to frown as the glimmering qi construct tried to pass, only to stick to the strands like a fly in a web.
She dismissed the wisp and stood, studying the barrier. There was no formation work that she could see, just the natural workings of a spirit in the spidersilk. Was it worth pushing through? Probably. She narrowed her eyes, peering through the strands. Inside was a funnel of webbing covering every surface, transforming the stone passage into a round tunnel. She eyed the little spiders above, some of them were developed enough to be minor spirit beasts. Perhaps…
"What was the disposition of the spirit beasts associated with the Hui afterwards?" Ling Qi asked.
Xia Lin paused in her study of the webs. "Scattered and disjointed, some followed the Hui unto death, some retreated to the woods and reverted to feral behavior, others merely requested a renewal of contracts with the Duchess."
Ling Qi grunted in annoyance, no easy answers then.She pinned a particularly fat and fuzzy brown specimen with a stern look, causing the hand sized arachnid to freeze in place. It was mid red in power, and she sensed just enough spiritual potency that it could probably understand intent. Letting musical flows of qi tinge her voice, she spoke softly but authoritatively. "If there is one who rules this place, I would parley with them. Go and inform your ruler."
She let the weight of her attention fall, and the spider bolted away, scurrying up into a crevice in the rock.
"You give up our advantage of surprise?" Xia Lin asked, more curious than accusing.
"If I had you cut through that barrier, it would do the same," Ling Qi replied. "And even if I could probably slip through, that would leave me alone with too many unknowns. If they're hostile and too strong, we can run and get the others, or bypass this place and risk the illusions with Lady Cai."
<Zhengui, I want you to burn everything and bring the passage down behind us if it comes to that,> she thought.
"Zhengui will be happy to squish dumb spiders who will not talk," her little brother asserted cheerfully.
Xia Lin nodded, seeming satisfied with her answer.
It was not long before the webbing blocking their path twitched, and the strands drew apart, fully revealing the funnel beyond, offering silent invitation. The moment that the strands parted enough, a wisp, dimmed to invisibility darted down the tunnel, and in her thoughts, she felt Sixiang focus in on the feed of information coming from it.
What lay at the end of the tunnel was a chamber woven of webs anchored to the chitinous limbs of a genuinely massive spider. They were still and empty of spirit though, an empty corpse and no more. Within the chamber itself however there were many hundreds of lesser spiders, six of them however were worth individual attention. Each one was larger than a human, closer to the size of a horse. It was difficult to get an accurate read on their cultivation, each one was covered in twitching hairs that disrupted the vision of her wisp and Sixiang's wind. They were certainly within a stage of her and Xia Lin however.
They hadn't noticed her wisp, instead they seemed to be engaged with debate among themselves, their frontmost limbs wriggling and gesticulating at one another, filling the chamber with the sound of scraping carapace.
She narrowed her eyes a touch as she realized the meaning of their movements and the vibrations they were sending through their webs. They were frantically planning an ambush. It seemed that there were at least two other greater spiders lurking about in the branching tunnels that left the chamber already.
Such a blatant use of a good faith request annoyed her. She would have to let Sixiang inform Xia Lin, whatever they did.
[] Refuse to enter, demand that they speak with you out here. You will not be trapped. If they refuse, have Zhengui seal the tunnel before you leave.
[] Enter and engage, but be prepared. Use the trappings of Cai authority and your own power to intimidate them into backing down. If they attack anyway, this is a grouping you can handle.
[] Pretend that you have not noticed their duplicity and play polite for as long as possible to draw out information. Subtly set yourself up to counterattack their ambush.
