Naruto: Max-Level Boss Drops Into the Starting Village, Instantly Carrying Team 7

【Naruto Fanfic + Transmigration + Full-Level Returnee + Jonin Teacher + Comedy + Ruthless / Not Soft-Hearted + Invincible Protagonist + HE】 Chen Yu transmigrated into the Naruto world for six years. A max-level account dropped into a beginner village, his daily routine was sunbathing on the Hokage Rock, skipping work, and slacking off while eating tricolor dango. The people of Konoha gave him a nickname: The Number One Slacker. Until he voluntarily applied to be the instructor of Team 7. A Nine-Tails Jinchuriki, an Uchiha orphan, and a civilian genius. Naruto: "I'm gonna be Hokage!" Sasuke: "I'm gonna take revenge!" Chen Yu: "Alright, listen to me." For the bell test, he made the three brats who couldn't stand each other learn to cooperate. For the Land of Waves mission, with one move—Wind Style: Great Breakthrough—he blew away the dense fog along the entire coast, sending the Hidden Mist's Demon, Zabuza Momochi, flying thirty meters away. Zabuza raised his sword: "Who the hell are you?" Chen Yu pulled out a stack of cash from his pocket: "Do you want to take this job or not?" When Uchiha Itachi appeared on the training ground, ready to torture Sasuke with Tsukuyomi, he finally realized— That slacking-off teacher was holding the entire power system of the Ninja World in his hands. Chen Yu looked at the sky in the distance and thought: Once these brats grow up, I'll unify the Ninja World before I leave. Not through violent conquest, but through the students he personally trained.
