Title: Fan Fiction, My Older Brother Teaches Me Ninjutsu
Synopsis: Tianyu, a genius with a high IQ, transmigrates into the Naruto world and becomes Uchiha Shui, son of Uchiha Fugaku, the clan patriarch. Uchiha Shui is born with the Mangekyo Sharingan. Though he only has a single-tomoe bloodline Sharingan, that's still enough to make him a genius. Ordinary members of the Uchiha Clan need many years just to awaken a single-tomoe Sharingan. His older brother Itachi patiently teaches him a great many ninjutsu, genjutsu, and taijutsu techniques. When he enters the Ninja Academy, everyone gets along with him except those who can't stand him. When he uses the Uchiha Clan's signature kunai-throwing technique, everyone is amazed. What kind of super taijutsu is that? Then Uchiha Shui uses Fire Release: Great Fireball Technique, and everyone cries out in even greater astonishment. Is this still just a genius? He's practically a god! He uses his dojutsu to heal their Hokage with ease. Everyone exclaims, “No wonder he's a genius. His intelligence is incredible, and his abilities are amazing!”
Everyone comes to admire Uchiha Shui beyond measure.
