The experiment begins!
Yakushi Kabuto inserted a syringe filled with Hashirama Cells into Kimimaro's heart, infusing all of the Hashirama Cells at once.
Instantly, Kimimaro's body trembled violently, veins pulsating on the surface of his skin, his heart beating fiercely, every muscle in his body writhing, forming a visage of Senju Hashirama on his chest.
Moreover, this visage seemed to be alive, moving over the entirety of Kimimaro's body.
"Kimimaro, activate your bloodline ability and force the Hashirama Cells into your spine, then use your osteoblasts and osteoclasts to encase them," Orochimaru instructed while aiding Kimimaro's chakra with his own, guiding it.
With Kimimaro's ability, he couldn't observe the cells directly and could only rely on his rough perception to encase what he could sense. As for the Hashirama Cells that couldn't be encased, it required a specialist like Orochimaru to guide Kimimaro from outside with chakra, allowing him to adjust.
