Lin Yuan, 26 years old, is an ordinary worker in an advertising company. On his first day of employment, he received a seven-page Code of Workplace Conduct. If you drink more than three mouthfuls of water in the pantry, you will be warned, and if your colleagues fail to submit their weekly reports, they will be devoured by tentacles - the company is eating people.
Each department has its own strange story: the elevator supervisor will die if he stares at it, the surveillance camera disappears at midnight, and the cleaning and mopping floors will accumulate water. Violators will be "performed" and no one will survive.
He discovered that completing KPIs can refresh the rules of life-saving: "Printers do not swallow living people" and "Stairwells can be reversed"... Use system loopholes to fight against the rules and reveal the truth about corporate sacrifices.
From surviving to counterattack, he wants to destroy the red building that connects the whole city, as well as the boss's true name hidden in the core of 25F.
