Right Fist Rule

Legend has it that when you meet someone who claims to be a time walker, you only need to stretch out your right fist and punch him in the face, and you can travel through time and space. This is the law of the right fist. That day, Yi An met a person who claimed to be a time and space walker. He immediately thought of the laws of time and space, so he stretched out his right fist and swung it hard at the man's face. Then, he really traveled through time and space... He was captured and thrown into a space-time prison.
