I fully approve.
Let's talk about what the current paradigm
is, before attempting to throw it out of a window.
- Some people (ninja) have useable chakra. Others (civilians) do not.
- Ninja can use chakra to enhance their physical abilities, but not their mental abilities.
- Ninja can use chakra to befuddle another person's senses (genjutsu), but not to affect their minds in other ways (barring very rare "utter bullshit"-tier techniques like Kotoamatsukami).
- Ninja can use chakra to heal others, but not significantly better than IRL modern medicine can.
- Ninja can utilise techniques based on fire, water, earth, lightning, and wind, though aquiring multiple elements is difficult.
- Ninja can utilise non-elemental techniques based on yin and yang chakra, but these seem either very basic (henge, substitution) or rare (shadow clone, needle jīzo).
- Some ninja have innate ninjutsu encoded into their biology (bloodline limits). Most do not.
- Ninja tend to operate in teams of three to ten. Smaller or larger groups are rare.
- The tech level is pre-industrial. Machinery is rare and expensive cutting-edge tech.
- Ranged weapons are either thrown or archery-based.
- Mechanised cavalry is non-existant.
- Ninja tend to be squishy. Defensive techniques are rare. Elemental defensive techniques can be countered by 20% of elemental ninjutsu.
- Ninja are highly mobile to compensate for their squishiness. They run fast, but with rare exceptions (now including all of Leaf), cannot fly or teleport.
- Permanent resurrection doesn't seem to exist.
- Most ninja are subject to ageing.
- Sealing research is dangerous.
- Learning Sealing is difficult.
- Sealing knowledge cannot be passed on perfectly between sealmasters due to everyone using a different sealing language.
I'm sure I could go into more detail, but I think that's enough to be getting on with.
I think we might want to research seal equivalents of the Simple Machines (pulleys, levers, etc.) that we can then build more complicated seal machines out of. Seals like
- Activate the next seal along the chain after x seconds.
- Stop the next seal along the chain from activating.
- Apply x Newtons of force in y direction.
- Change the angular momentum of the connected object by x amount.
- Change the temperature of the connected object by x amount.
- Change the speed of the connected object by x amount.
- Store "0" or "1" until you have chakra flow into you, in which case flip your stored bit.
- Check the stored bit of the connected seal and output chakra flow if it's "1".
Really simple things that can be used as standardised parts.
