Immortality Martial Arts: I Kill Demons and Conquer the Heavens

I saw a woman being bullied and tried to break up the fight with good intentions, but was knocked unconscious with a stick. When I woke up, I traveled through time! Chen Le doesn't want to time travel, he doesn't know martial arts, he's afraid of fighting and pain, who wants to fight those monsters! Look at those flying people, they look like King Kong, I can't beat them. What? Got a golden finger? That's okay, okay, how can it be done without cheating? Um? Still need to pay? Life? Whose life span? Mine! ?
