Lin Mo joined the company for a high salary, but found that the company's rules were strange: "Don't reply to messages at midnight" and "Don't drink yogurt from the third row."

This is an extreme survival story about migrant workers in a weird workplace, using workplace wisdom to fight against supernatural forces.
