Naruto: Unify the Ninja World and Ascend from the Same Place

My name is Lin Feng, and I have traveled to a space-time matrix composed of seven parallel Naruto worlds. The system prompts that as long as the unification of the seven Naruto worlds is completed, I can become an immortal instantly and live forever. The mission is very difficult, but luckily you can cheat a bit. So I decided to take Senju Hashirama to see how Tobirama died. Take Master Madara to see how he got his heart ripped out by Black Zetsu. Show young Sarutobi how he was fucked by Orochimaru. Take Minato to see how Naruto was ostracized. Take Tobirama to see how Senju and Uchiha died. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
