"Danzo, Chiyo-"
Tsunade's expression grew grave. "Those two only fought each other head-on once during the entire war-sure enough, I was on a nearby battlefield at the time too."
"Fate," Xue Ge said.
"Haha, I suppose you could call it fate." Tsunade smiled and shook her head. "Still, surviving in an environment like that couldn't have been easy."
Remembering his first four years after Danzo took him in, Xue Ge nodded in wholehearted agreement. "Indeed."
Meanwhile, Shizune examined Xue Ge's prosthetic limb. After peeling back its thin layer of imitation skin and seeing the fine markings underneath, she asked, "What are these markings for?"
"Those-" Xue Ge took the prosthetic limb back from Shizune and reattached it to his shoulder. Chakra threads slowly extended along the markings.
"My control was poor when I was learning chakra threads. These were specifically made to help maintain them," Xue Ge recalled. "As for now, I'm used to it."
"Then could you carve more channels inside to imitate the chakra pathways in a real arm?" Shizune asked curiously.
She had studied the basics of medical ninjutsu too, and knew more about the human body than Xue Ge himself did.
But clearly, Shizune currently placed more emphasis on theory than practice.

"So simply changing the internal structure of a wooden prosthetic limb to match a human body wouldn't accomplish anything."
After a moment's consideration, Tsunade added, "But apparently the Sand Shinobi have a way of making puppets use ninjutsu-I don't know exactly how they do it, though."
"Oh, I see-" Shizune looked
