Qin Chu was originally a low-level cleaner in a certain unit. Due to his accidental binding to the "Villain Tyrant System", he was involved in countless unlimited dungeons with the background of workplace and officialdom. In these dungeons, he must play the role of a villain, a corrupt official or a black-hearted entrepreneur, use various means given by the system, play tricks within the rules, suppress hypocritical villains, and accumulate villain points to exchange for resources and intelligence for official promotion in real life. Returning to reality, he used the experience and system rewards accumulated in the dungeon to bring down the evil leader who suppressed him, gradually uncovered the high-level corruption network, started a counterattack from the cleaning staff, and finally became a single-handed workplace overlord.
