Unemployed programmer Chen Mo delivers food during the day, but in the early morning he receives "zero o'clock orders" that he cannot refuse.
There is no merchant for the order, and the delivery fee is not money, but a 24-hour lifespan. Every signer will die the next day; for every order completed, Chen Mo can live one more day.
The system told him that sacrificing one person could prevent a greater disaster. Chen Mo began to struggle between survival and conscience. Until one day at midnight, a new order appeared again - the recipient was actually his sister Chen Xi who worked in the emergency department.
This time, he decided to refuse delivery and track down the truth behind the zero-point system.
