Naruto: I Am a Medical Ninja, and I Start with Tsunade's Tits.

Yun Yi traveled to the world of Naruto and witnessed the battle between Hanzo and the Sannin of Konoha. When I thought I could just be a passerby silently, I suddenly awakened to the "random selection system". As long as I make the corresponding choice, I can get rewards! And the first reward is the body of Aoki, which has extremely strong ability to heal itself and treat others! Moreover, Tsunade, who breasted on the spot, said she couldn't stand it! Immediately afterwards, the system's rewards became increasingly outrageous. [Reward for successful selection: Space Ninjutsu·Space Anchor] [Successful selection to obtain reward: Panlong Spear] [Reward for successful selection: Eight Gate Dunjia] [Choose successfully to get rewards...] On a battlefield somewhere, I watched Yun Yi happily shuttle through the battlefield with sparks and lightning all the way! The Third Kazekage Rasa: He is a medical ninja, right? The Third Tsuchikage Onoki: "Well, it looks like... It should be so!" During the Fourth Ninja War, Seeing Yun Yi kicking Liu Daoban into a folding screen, everyone was stunned! "Med... Medical ninja?" In response, Yun Yi just smiled evilly, "It's time to bring a little medic-nin shock to the ninja world!"
