Within the High Plain of Heaven.
Uchiha Mirai stroked his chin as he carefully examined the white chunk of flesh before him.
The flesh clearly looked as though it had been left sitting for many years, yet its cells still emitted an intense pulse of life.
They were indeed Hashirama Cells!
He had obtained them from Danzo's Root storage room!
These extraordinarily special cells required specially made cultivation tanks for storage, but the Uchiha Clan Compound did not have such facilities.
Therefore, the instant Uchiha Mirai acquired the Hashirama Cells, he stored them within the High Plain of Heaven for optimal preservation.
He also imposed a rule over a small area, allowing this chunk of flesh to remain in its ideal state of preservation indefinitely.
As Danzo suffered humiliation in this world, he probably never imagined, even until his death, that the treasure he had always obsessed over was sitting merely a few dozen meters away from him.
"It's time for the Hashirama Cell transplant."
Uchiha Mirai stared seriously at the chunk of flesh.
The reason he had not undergone the Hashirama Cell transplant before now was that the procedure was not without risks.
In the original story, it seemed that only Uchiha Madara and Obito had transplanted Hashirama Cells.
There were very few cases to draw from.
Before completely eliminating Danzo's threat, Uchiha Mirai had not wanted to take that risk.
He could certainly use the rule power of the High Plain of Heaven to protect himself, but the key issue was that transplanting Hashirama Cells meant blending the powers of the Senju and Uchiha clans.
He was not sure whether he could use the Mangekyo Sharingan's ocular power during that process.
In theory, there was no upper limit to his control over the rules of the High Plain
