Naruto: I, Uchiha, Apprentice to Senju Hashirama

Uchiha Linhai, a time traveler with the memories of a forty-year-old adult, opened his eyes and became the young master of the Uchiha clan, and the grandson of the legendary Uchiha Madara! A hellish start? The entire clan is under round-the-clock surveillance by the Second Hokage Senju Tobirama, and may they face a crisis of genocide at any time? Don't panic! With his adult mind and full-level ninjutsu talent, Lin Hai was able to fire two B-level ninjutsu in a minute at the age of six, instantly alarming the top brass of Konoha! Senju Tobirama: "This child's talent is terrifying and he behaves like an enhanced version of Madara. He must not be left here and must be eliminated as soon as possible!" Senju Hashirama: "Tobirama, shut up! This child has the true will of fire. He is the hope of Konoha's future. I will personally accept him as my disciple!" When Madara Uchiha's grandson became a close disciple of the "Ninja God" Senju Hashirama, the entire ninja world trembled. Many years later, when the Ninja World War broke out, Lin Hai stood at the top of the battlefield, Susanoo in his left hand, and holding Senjutsu Chakra in his right hand... "Second Generation Master, actually you read it right. Not only am I an enhanced version of Madara, I am also an enhanced version of the First Generation!"
