Kill Uchiha Madara in Seconds, I Am a Max Level Boss

High school student Xu Fengri accidentally obtained a full-level time travel system, traveling through different worlds and defeating full-level bosses as bosses. Uchiha Madara? I have completed it more than 300 times. Uzumaki Naruto? That's my little brother Uchiha forces the king? Sasuke is just the little pussy king, I am the big pussy king. What are you talking about that Luffy who drives the boat? Don't be ridiculous, that's my good brother. Vegeta and Tartaroth? Last week I drank their grandson's full moon wine. Oh, you mean Beria. He is indeed harder to beat. I have to call my American Iron Man brothers over. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
