Wood Release and Human Puppets

What exactly was Wood Release? Back when Qi had still been an anime fan in his previous life, he had already been intensely curious about that question.

Yamato's version clearly did not count. If Wood Release had only that much going for it, Senju Hashirama would have been beaten by Uchiha Madara until even his own mother could not recognize him...

The Senju Clan gave Qi the best answer. They had records of Senju Hashirama's battles. Of course, considering that Hashirama had been one of their own, those records were inevitably embellished. So Qi had gone to the Uchiha Clan as well, and what the Uchiha showed him were Uchiha Madara's battle records.

That was easy enough to understand. Senju Hashirama and Uchiha Madara had fought each other more often than anyone else, so most of these so-called battle records were records of their duels. In that era, only when those two met did a fight have any real substance. Against anyone else, they generally won in seconds, making records unnecessary.

Thus, after combining the perspectives of both the Senju and Uchiha Clans, Qi finally gained a rough understanding of Wood Release.

First, just as he had previously learned, Wood Release truly existed as a medium. In other words, the strength of one's Inner Body directly determined the power of Wood Release. Yamato's Wood Release was weak primarily because his Inner Body was too weak. Being able to cast the low-level forms of Wood Release ninjutsu was already his limit. Not just him—even Danzo in the original story had been the same. Their Wood Release had all been knockoffs...

The Senju Clan's definition of the Inner Body followed the standard ninjutsu system. The Inner Body was the energy inherently contained within the body, which could be directly used after cultivation.
