Having settled on his goal, Sarutobi Toru first began refining the Black Zetsu sealed within him.
The Ten-Tails had yet to transform into the God Tree. Though it was already tall and conspicuous in the desert, it would at least not be discovered anytime soon. He did not need to worry about anyone coming to his doorstep. This was the perfect time for Sarutobi Toru to refine Black Zetsu.

It was not until the sun began to set that Sarutobi Toru
