Delivery boy Jiang He was overwhelmed by rent, fines and family medical bills. After placing an order for nighttime cold storage, he was forced to bind the doomsday countdown system. The system does not give money or send warehouses, it only requires him to publicly record early warnings.

But the signs slowly came to light, and when the gray rain fell, everyone discovered that the delivery man who had been scolded as crazy had already moved boxes of supplies into the old warehouse.
