From Postman to Lord of Weirdness, Starting with a Loan

Zou Yan lost his memory and became an ordinary postman. He also wanted to be an ordinary person, but the person he delivered to was an immortal who was beyond the reach of ordinary people. He thought life would always be like this. But when the sister who picked him up and was called the disaster star was forced to drop out of school and was taken away, he realized that only with power and status can people have the right to speak. From then on, Zou Yan had a second personality, and the system also had a loan function. Slowly, Zou Yan discovered this loan function. Even if the loan was from a loan shark, he could still borrow without capital through a card bug. From then on, there was a post office in the world that was independent of the Postal Service, and the chaos began.
