Salted Fish Three Dozen

Thirty years are exchanged for three years and one day. During these three years, you can choose the role you want in the new world, and have the authority to change your role three times. This is a deal between Chen Xiaodong and the City God "Lao Bai". There is no golden finger, no system, only one identity is given to him, and the rest is all up to him. For successful people, such a transaction may make them hesitate. After all, it means exchanging ten years of life for one year. But for a salty fish in the real world like Chen Xiaodong, it is a dream come true. After all, he has been dragging his feet for a long time, and even a moment of indulgence is extremely tempting to him. The only thing Chen Xiaodong couldn't figure out was that it was easy to understand that one year was exchanged for ten years. Could this extra day be to give him time to prepare his birthday materials?
