Zhou Xiaoxing, an international student from the Department of Computer Science, returned to his hometown of Xu City. The welcome banquet almost turned into a feast for the whole village because his parents forgot about his seafood allergy. On the verge of death, he was accidentally bound to the city's wealth system: he received more than 30 million yuan every day, a total of one billion yuan a month, but he had to spend it all within the administrative scope of Xu City within ninety days. It cannot be purchased online or transferred to other places, and the money spent must be real and reasonable. In order to find out the bottom line of the system, Zhou Xiaoxing began to test the rules frantically. Improving the life of his family, acquiring companies on the verge of bankruptcy, investing in unpopular industries... As the mysterious girl Yin Yin breaks into his plan, a frivolous billion-dollar challenge begins. With more and more money, Zhou Xiaoxing discovered that spending money reasonably in a small town is a hundred times harder than making money.
