In This Strange World, I Am the Ever-Changing Martin

I don't know when weirdness began to appear in this world. In order to fight against weirdness, human beings have awakened people. The awakened person's body and soul are extremely powerful. After cultivating to a certain level, they can move mountains and fill seas, extend their lifespan, and kill powerful weirdos. However, weirdness grows quickly and in large numbers. Humans can only survive in the cracks. It was not until a crazy six appeared that mankind stood up again.
