Naruto: Starting from Konoha Hospital

Ling Yu, a master of surgery, once traveled through Hokage and became a war orphan working as a handyman in the original Konoha Hospital. It was the end of the battle, medical ninjutsu was beginning to emerge, and human life was like grass. Watching the ninja bandage the wound with brute force, Ling Yu silently picked up the scalpel. Debridement, suturing, aseptic operation... Modern medical skills are beginning to show their miraculous effects, and the [strongest medical assistance system] is accidentally activated - treating the ninja, and its abilities can be copied! [Heal the genin and get the "Chakra Refining Method·Introduction"! [Assist Tsunade and obtain "Palm Immortal Technique Experience·Advanced"! [For the life-saving grace, the Uchiha jounin gave me "Chakra Control and Mastery"! While others were practicing ninjutsu, the talent of the entire ninja world was flowing under Ling Yu's scalpel. From a hospital handyman to a three-war medical sage, he used his medical skills to bring the dead back to life and weaved a web of life-saving love that enveloped the entire ninja world. Until the chaotic night of the Nine-Tails, in front of the seriously injured Yondaime, Ling Yu's fingertips glowed with chakra: "Namikaze Minato, I saved your life. How about using the flying thunder god's technique as a medical fee?" This is a surgeon who uses his medical skills to become the strongest legend in the ninja world of blood and fire!
