On the third day of the apocalypse, Wei Xiao was trapped in the first dungeon, and he was the only one of his teammates who died. He squatted in the corner and pulled out his phone. On the screen was the unfinished copy design draft before the end of the world. The monster spawn point numbered 001 is exactly the same as his design draft. He looked up at the mutated dog that was eating the corpse, and then looked down at the weak spots marked on the design draft. Three minutes later, he stabbed the mutated dog through the back of the neck with a steel bar. From that day on, all copies were half-finished in his eyes. Others are surviving in the dungeon, while he is changing the rules in the dungeon. It wasn't until the first copy he designed was included in the system and survivors around the world poured into the trap he had set himself that a woman named Ruan Qingshuang found him. She said that the way you designed the copy looked like an old friend.
