Naruto held the Hashirama leg bone cultivated from Rock Lee's cells against Rock Lee's right leg to compare them.
Since he had obtained measurements of the bones in Rock Lee's limbs beforehand, there was no risk of a mismatch in length.
The Byakugan could see through everything. When Naruto took out the fresh, milky-white section of bone, Hinata used her Byakugan to examine its internal structure.
"What an amazing structure. Naruto, Older Brother, I've never seen bones built like this before. They seem different from ordinary human bones."
As Naruto concentrated on fitting Rock Lee's new leg bone, he explained to Hinata, "That's right. I cultivated this self-repairing bone from Rock Lee's cells."

After finishing with the right leg, Naruto glanced at the operating room clock and froze.
"Four hours just to deal with one right leg? Looks
