I Exchange Everything in the City

Time travel to a university with a terminal illness and a notorious reputation. Lin Yuan originally thought that the beginning was the end. Go to the Wanjie Material Exchange Mall to bind successfully. The system has only three functions: storage, purchase, and return, and it has no intelligence, no prompts, no tasks, and no analysis. Feng Shui's bad situation, evil spirits causing chaos, Xuanmen's grievances, the truth and the way out behind all these need to be discovered by himself. Since then, there has been a new addition to the urban metaphysics community, and he has never just returned or exchanged items.
