Naruto: Konoha Research Monkey

[Making up for regrets + funny + cool writing + invincibility + single heroine Tsunade or harem? Thank you for the invitation. I was just born in Konoha. I am the third generation son and the Prince of Konoha. I worked overtime until I died suddenly. When I opened my eyes, I saw a monkey's face. I was so scared that I kicked him away. Later I found out that he was actually the Third Hokage Sarutobi Hiruzen. I also became a person who didn't exist, Sarutobi Asuma's older brother - Sarutobi En. Asma: Brother, would you like to try one too? Yan: No, I only smoke Ruike 5. Danzo: Biwako, tell me the truth, is he really not my son? Si-Hai-Wei-Mao-Xu-Zi-You-Wu... (The corpses and ghosts are sealed away) Hiruzen, please stop forming seals, I'm afraid The reincarnated eye Senju Hashirama and the six magatama reincarnated eye Uchiha Madara are my bodyguards, so I asked who else!
