Cell study (52)

Seijuro knew for a fact he only had like 3 weeks off. They had, after all, just completed an A-rank mission—their first mission outside the village—and not many Genin could say they had an A-rank mission under their belt.

They, in fact, shouldn't have an A-rank under their belt. A-rank missions were what high Chunin and Jounin did, if he were to say it how things are.

Genin do D and C ranks.

Chunin do C and B ranks, sometimes A.

Jounin do A and S ranks. That's it for the most part. A-rank missions pay a shit-ton of money, so, during that time, he had Yui buy him some lab equipment—nothing too big—alongside some poison books.

Just in case. He needed to analyze Nawaki's blood, see what made the boy tick. Anyway, he had 8 clones work on the Mystical Palm Jutsu.

And with 3 weeks, multiplied by 8, that should be like 24—so roughly 5-ish months' worth of grinding. However, taking into account repetitions, that 5 months was closer to something like 3 months—3 or 4 months.

Still, with his talent, that was plenty enough. Plus, he already had a grasp on medical ninjutsu, so it wasn't that hard for him.

Sealing would be next. He was still working on his sealing proficiency. Truly, a 10-year-old with so much range—fun.

Well, he could kill a Jounin with enough preparation. Thinking about it deeply, Jounin were still human. Even a mere Genin could kill a Jounin under the right conditions, which may include the Jounin being way too freaking confident.

Anyway, this was how his training regimen went:

[Week 1 – Foundational Mastery]

In the first week, the clones had no real control. Their chakra signatures fluctuated constantly, surging and dipping like toddlers discovering fire for the first time. Healing a scratch? Easy. Healing a muscle tear? Disaster. Clone #7 caused a squirrel's leg to regenerate sideways.

He had decided, for the better good of everything, to mercy-kill the squirrel. He truly was looking like a sociopath right now, with this unmoving, uncaring expression as he did such an act to an animal.

He might have gone to the Forest of Death and studied more on the chakra-enhanced animals which were there.

He had his clones each try out a different method of healing, so that the repetitiveness was lessened—because what was the point of learning the same shit a thousand times?

Sure, he may not have that many clones, but he was studying efficiently.

So, he took notes. Hundreds of pages.

How long did it take before a typical wound sealed? What chakra ratio worked best for birds versus mammals? How many millimeters deep could chakra penetrate before it hit vital organ pressure thresholds?

He mapped it all. This would've been easier with a Byakugan, but oh well, you take what you can get.

He sighed a bit.

[Week 2 – Internal Healing, Organ Precision]

By now, the clones could close surface wounds within seconds. So the easy part was done. Took 8 weeks though—technically only 1, but with 8 clones, that's 8 weeks, so like 2 months to learn that shit.

He sighed a bit—now for the internal shit.

The goal? A ruptured artery in a sedated rabbit.

Clone #4 failed. It overcompensated, sealing the artery but also hardening surrounding tissue. The rabbit woke up angry and almost went rabid.

Clone #6 got close, but his chakra was too slow. The blood loss was too quick. Another failure.

Seijuro himself stepped in.

Learning from his mistakes, he didn't jump in headfirst. He first slowly introduced his chakra to the animal's body, watching how it reacted to it, then slowly increased the dose to make sure the beast's body was used to his chakra.

Only when the beast didn't view his chakra as a virus did he start healing the beast. He had to be very cautious—but that didn't matter much.

[Week 3 – Layered Healing & Chakra Rotation Theory]

This week was mostly figuring out how to apply layered healing—so healing that came in waves. Was pretty hard. Obvious answer was like Yang Release, but that shit wasn't just available everywhere.

Sure, the Akimichi clan had Yang Release, but they didn't necessarily know how to apply it to other people other than themselves.

He even went to the trouble of buying some of their pills. Didn't eat them—shit wasn't meant for him—tried it on a few animals, but didn't see much progress.

From Week 4 to 8, all he did was simple, really—he just tested the limits of healing, studied a couple of books on anatomy, and studied some of Nawaki's cells.

Seijuro looked at Nawaki's cells through the microscope. They were so damn active. The cell division was happening like crazy. His cells seemed much livelier, having way more energy, way more chakra.

While Seijuro's cells were... not the best. They could be considered as being asleep. Nawaki had so much more vitality.

He didn't test out Mikoto, for some reason. He didn't even plan on experimenting with her blood, even if the Uchiha were a clan he wanted to study up close.

Hm. Maybe get a piece of Kushina's blood. Since she was like good enough to be a Jinchuriki, he wanted to study it so that he could replicate it—so that when it came to his time, he would be fine... for the most part.
