Dream Chasing Begins at Hogwarts

Everyone has dreams. In this busy world, are there many regrets? The dream chasing system of the heavens, the escaped one, helps the protagonist Zhang Fan to realize his dreams in each world. Zhang Fan, an upright loser, had worked hard for ten years and saved up. He was about to get married and have children, and live a life of a hot bed with his wife and children. However, he was told during the physical examination that he had cancer. At the last moment of his life, he was favored by the dream chasing system of the heavens and went to each world. What wonderful stories will Zhang Fan have in these worlds with the help of the system? The first world, Hogwarts, will be solicited from readers for their opinions later. This is my first time writing a book, so please read it and give your opinions. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
