Of course, I had some original ideas, but there was nothing complicated about them - a normal Fuinjutsu master could crack such tasks, like modifying a sealing scroll or stabilizing a clone, like peanuts, if he thought about it, of course.
Having determined, after many attempts, that the most likely sealing chains didn't fit, I decided to look at the problem from a different angle - if the Shikon no jutsu modification didn't fit, then the problem might not only be with it, but with Kage Bunshin no jutsu as well. Upon reaching this simple fact with the help of the clone's clue, I felt the urge to bang my head against the wall! Of course!
Why would I need to embody chakra with a copy of consciousness in a body when all I need to do is fix it to an existing corpse, not create a likeness! After a little insight, the matter obviously went well, and soon I picked up a more or less suitable combination of forty-six hand seals (as well as eating supplies just incredible way) and the controlled corpse could not only move briskly, but even with some difficulty to talk under the control of the artificial consciousness, but only immediately found out one small detail and a huge disadvantage.
Closing all the sensations on the consciousness of the clone, I was deprived of any connection with the working technique, but it could be survived or bypassed by other means, if the resulting technique really worked normally, but after a dozen minutes the animated corpse returned to its original state. After beating on this problem for a while, I found out that the chakra-based consciousness loses all the invested reserve for the simple reason that it is not in its keirakukei and there is no medium in the person of shinobi, which keeps the technique in working condition.
The kage bunshin simply cannot hold his chakra without the restraints of someone else's system and it dissipates into space. After thinking about it and getting nowhere (as well as spending an obscene amount of bodies on experiments), I decided to take a different approach - if I couldn't do it all with a single ninjutsu, albeit with a partial bias towards iryo-jutsu, why not use another area of the shinobi path that I knew well?
After some thought, I used my clones to dig through my own library holdings from my father, and then through the pile I'd received from Mito-chan, and in just a couple of hours I'd created a seal that was quite intricate in essence but not in execution, capable of acting as an anchor for my consciousness and my chakra.
Of course, for this purpose it had to be applied first, and then to use the new technique on a suitable corpse, but this is hardly a big price to pay for a fully autonomous puppet, capable of acting at any distance from the creator and without the weaknesses of all clone techniques. Except that the new jutsu, which had previously required only the time of folding seals to create, required quite a bit of preparation time and tools to apply the fuinjutsu.
Given the fact that I had gradually begun to learn with Mito how to transfer some of the simple seals to hand-based seals (the first step of creating seals with a simple touch, similar to what two of the three sannin had used when they first met Naruto), this was something I could remedy, which I did with renewed enthusiasm. It wasn't particularly difficult, but I had some practice, so converting the intricate pattern into eleven more hand signs was no problem.
When I got a more or less sane result of fifty-seven hand seals with no visible flaws, I breathed a sigh of relief - in the week and a half that I had been almost entirely engaged in development and experimentation (except for training, of course), so much nerves, chakra, and materials had been spent (and the clones still had to deal with the dismemberment of unfit bodies to minimize losses) that it was impossible to be frankly happy.
