All the successive stages from and to, designed for four months with the use of appropriate drugs that facilitated a very complex and at some stages, painful process, but even so, requires the level of at least a full-fledged jonin to avoid serious consequences of the application of the complex of seals for this period.
The stress on the body and keirakukei isn't going anywhere, even if you stretch it out over time.
Chunin are already at risk of being in the position of the first test subjects - ending their ninja career due to extensive damage or even dying. In addition, while the complex is in effect, the bearer, for obvious reasons, will lose most of his ability to use chakra, and certainly not the use of even medium strength ninjutsu, which makes it undesirable for active ninjas.
Theoretically, by increasing the adaptation period by three or even four times, the negative side effects will go down, but even so, it is impossible to completely eliminate them - although the body of chakra users has a much greater adaptive ability, but everything has a limit.
Besides, sudden changes in appearance might be more noticeable to outsiders, causing unnecessary questions, but if for a year or two... You can always blame it on the procedures provided by the Konoha Hospital for very wealthy clients, and my status will serve as a perfect screen.
Especially since I've been providing some of the clan's women with some appearance enhancement services with that in mind.
- Well done, - I praised the laboratory doppelgangers, - have done a great job, and even though the application of the complex of seals is very difficult even for me, but the result is worth it.
- You created us for this purpose," shrugged the kage bunshin indifferently, "what should we do next?
- Besides this one, are there any other test subjects left? - I asked them.
- Just two, one of which needs to be treated properly so that it can be used in other experiments.
- You do that and send Kaguya to get the material - the last mission was a success in every sense," I nodded to the four of them, "and then start scrutinizing old man Hishi's records - even if I can use a tenth of what's in them, it'll increase my survival rate.
- We'll do it, Boss," the permanent residents of the lab stretched out.
- You already have the records, so go ahead," I waved my hand at the kage bunshins and added, taking a moment to remember Kumo's name, "and don't forget to put that Saya back in the scroll-I have plans for her.
- Will do.
- Now with you, I turned to Kaguya, who was waiting patiently for his turn, - how's the training going?
- Unexpectedly effective," the kanpeki ningyo reported, "the new fighting style may be different from what we're used to, but this body remembers the movements ingrained in its reflexes, and only the Shikotsumyaku (Dead Bone Pulse) is causing some difficulty, But not taijutsu," he shrugged, "although the former owner is not a talented teacher - they have a clan that does not teach normal training, but rather blood and pain, and if you don't get killed right away, it's enough to rest.
