After the sky splits open, ability users are forcibly dragged into the Death Game Corridor to clear stages and obtain source matter; failure means brain death. Lu Yin, a convenience store night-shift clerk, awakens a nonexistent SSS-rank Rule Tampering ability. His first reaction is to delete the system reporting button, from which point the panel only displays an F-rank ability that makes boiling water cool down a little faster. The strongest person becomes a guild porter with a monthly salary of 800 source matter. He uses broccoli to chase and kill the director, uses 'early arrival' to clear the midnight subway, and everyone thinks he just has good luck. Until he establishes a guild with only one person, discovering that the corridor is not a game, but a building his dad has been carrying on his shoulders inside for twenty years. He has only one chance left to rewrite the rules.
