Lin Yuan, the lowest genetically modified cleaner at the lunar base, numbered LUNAR-7. During a routine cleanup, he was recognized as the master of the ancient immortal formation in the abandoned restricted area, and he has since had "administrator authority" over the entire back side of the moon. He could see every corner of the colony through the "monitoring" of the ruins, and saw how the mad scientist used genetic experiments to gradually awaken the ancient evil deep in the seal. Faced with the Cthulhu-like existence that was about to awaken and the various forces that were eyeing him, Lin Yuan chose to live in peace. He used the simulator in his mind that could deduce the outcome of death, while pretending to be an ant and continuing to sweep the floor, he quietly dug holes, handed knives, and fixed bugs to various forces. When the evil thing finally opened its eyes and everyone thought the end was coming, Lin Yuan silently pressed the "system restore" button of the ruins.
