I Must Become Weak

It's still good, you can watch it to pass the time. It's about the protagonist who traveled through time and became invincible and unable to control himself. Because of fighting with the top forces in the big world, the small world where his sect was located was destroyed. Then the remaining people in the small world scattered and fled to other worlds. The protagonist and his master also began to wander, looking for the world to return to the protagonist, the earth. That's it for now. (The protagonist doesn't know how strong he is, nor how powerful the God-Emperor is, so he doesn't dare to take everyone to gamble. His master believes that the earth is a top-notch world)
