"Next up is my business," said Sakura as she moved her wrist and snapped her fingers. The opaque incubator shattered, revealing a milky-white arm that had been cultivated inside.
Compared to Sasuke's other hand in the future, this one was only slightly paler.
"All right, it's ready to be attached," said Otsutsuki Sakura as she took the arm. She had other ordinary shadow clones bring the future Sasuke to the operating table, opened the healed-over skin, and attached the cultivated limb. Using Chakra Great Harmony, she connected their meridians and blood vessels, and the nervous system.
In less than three minutes, Sasuke's left arm had fully recovered as if it had always been there, and what's more, he no longer needed to form seals to use Ninjutsu with this hand.
