Shizuka was first taken aback, then felt the invisible, heavy pressure resting on her shoulders as she opened the scroll.
After reading the introduction to the Medical Transfer Technique on the scroll, she still did not understand. It was clearly a technique that could be used at a patient's critical moment, so why did so few Medical Ninjas learn it?
Medical Transfer Technique Ninjutsu Rank: B Effect: Takes over the circulation of Chakra within another person's body. When a patient's heart stops, it can replace the heart and forcibly use Chakra to drive the body's blood circulation, prolonging the patient's life until the caster's Chakra is exhausted.
Tsunade saw the deep confusion on Shizuka's face and shook her head helplessly.
"This technique was created by my clan's ancestors during the Warring States Period, when a noble hired the Senju Clan in hopes of transplanting a heart to extend his life."
"Though it was theoretically feasible, it never succeeded despite numerous experiments."
"The only successful case was when an elder's child was born with congenital heart disease. They succeeded only by trying it with a hopeful mindset."
"Only afterward did they discover that it could only be used on people with the same Chakra origin—close relatives—or people with similar Chakra."
"In short, this technique can only be used between blood relatives or masters and disciples. Otherwise, the body's natural rejection of foreign Chakra will prevent the patient's blood from circulating smoothly."
Only then did Shizuka understand why no Medical Ninja would learn this technique. It was truly useless, almost never applicable.
In the history of the Shinobi World, it had only succeeded once.
Afterward, Tsunade prescribed Tingxiang some restorative medicine and a week's worth of Healing Potions, reminding her to visit Konoha Hospital every week for the same medicine.
