Programmer Zhou Ming died suddenly at the annual meeting. What I thought was the end of my life turned out to be the starting point of being an intern in the underworld, collecting "karma debts" for the underworld. Returning to the world, Zhou Ming is no longer an old scalper who can be manipulated by others. The local government's black technology ran into the unwritten rules of the workplace. When karma became a quantifiable performance indicator, Zhou Ming's revenge had just begun. This is not only a settlement of personal grievances, but also an ultimate game about fairness, dignity and systemic evil.
