The King of Fighting in All Realms

Travel through another world and be reborn to obtain a super invincible fighting system, referred to as the Pingtou Ge system. As long as you fight, you can upgrade infinitely. What is our slogan? I have the final say whether the world is in chaos or not. Adhere to the style of doing things if you don't accept it. The motto is: either there is a fight or there is a fight on the way. Let's see how the protagonist uses the super invincible combat system to travel across the world. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
