When Orochimaru heard Qingyun's question, he gave a sly smile, ran his tongue around his lips, and looked at Qingyun. "Soon. Speaking of which, while escorting the Queen of Roran to the Land of Demons for you, I came across a village afflicted by a strange illness. I found an excellent test subject there.
"By studying his bodily fluids, I discovered that he could neutralize the aggressive nature of hashirama cells. Combined with white zetsu cells, once I determine the precise dosage for each injection through experimentation, we can begin implanting hashirama cells."
Qingyun nodded in understanding. The excellent test subject Orochimaru mentioned was probably Uchiha Shin.
He had never expected his involvement to lead Orochimaru to meet Shin ahead of time. In the original story, Shin had an extremely unusual constitution. Any virus that entered his body would be broken down and ultimately become nourishment for him instead.
Strictly speaking, hashirama cells could also be considered a virus. This virus spread with incredible aggression. Once inside someone's body, it would rapidly devour their cells to strengthen itself, turning that person into a lifeless tree.
In the original story, Orochimaru had injected hashirama cells into Shin's cells, then grown an artificial arm for Danzo. Using that arm, which contained hashirama cells, Danzo had implanted numerous Sharingan in it. It was utterly disgusting.
"How long will it take? I still need to make some preparations before we implant hashirama cells in Shisui!"
Qingyun glanced with mild distaste at Orochimaru, who now seemed to stick out his tongue every other sentence, and asked in an even tone.
"Hmm... within six months!"
After considering it for a while, Orochimaru gave Qingyun a definite answer.
Qingyun nodded without speaking. He glanced at the small figure beside him, lost in thought, then turned and left
