Akaseki stopped dwelling on whether it was legal and instead began considering what Orochimaru had just said—
What did he mean by plundering or not plundering? Akaseki only felt the impact at first and had not thought too deeply about it. But when Orochimaru said, "The First was probably like this," Akaseki remembered that Black Zetsu's Wood Release differed from the First's legendary "Wood Release."
More precisely, more than one Wood Release ninja had appeared during the Warring States era. But—the "God of Shinobi" had only ever been one, and there were vast differences between one "Wood Release" and another!
All this time, everyone had believed it was because the First himself was strong. The same Wood Release was ineffective in other people's hands, proving that it was Hashirama Senju who was powerful, not Wood Release.
But now—Akaseki took things a step further and recalled the two different kinds of "Magnet Release" he had seen.
There was no denying that Hashirama Senju had to be powerful to make such a name for himself with Wood Release alone. But—could Wood Release itself also have been different?
At the same time, Akaseki naturally thought of what Black Zetsu had previously called "the power of the God Tree." That useless Ashura seemed to have gained a portion of the God Tree's power in his Wood Release because Uchiha Hagoromo had favored him.
Akaseki naturally made the connection. Could the First also have drawn upon the God Tree's power to some extent, making his Wood Release fundamentally different?
On this matter, if Black Zetsu had not lied, then the First had definitely been Ashura's chakra reincarnation!
Akaseki had another piece of evidence for this.
The replicas given to the Uchiha Clan as compensation had been crafted by the First using his own Wood Release.
