The real world is eroded by "weird pollution sources". Every 49 days, a "weird city" alienated by rules will appear. The residents of the city will collectively turn into inhuman monsters at midnight. The protagonist Shen Yan was originally an ordinary programmer. After witnessing the tragic death of his girlfriend in the strange city, he accidentally awakened the "administrator" authority - he was not the creator of the main god space, but a "bug fixer" sent by a higher civilization. He needs to break the rules by repeatedly entering the strange city and cover up the truth that human civilization is about to collapse.
