Wang Yuhan is a college sophomore who lives in the 21st century and has nothing to do all day long, but he is extremely fascinated by novels about cultivating immortals. One day when he went to a bookstore to buy novels, he mistakenly read a mysterious black book. This book changed his life. As a result, his mind and soul traveled through time and space and possessed a good-for-nothing young master from the Wang family in Night City on the Tianhai Continent. After coming to this continent, he discovered that Everything here was so strange. Here he experienced the ruthlessness of the family and the warmth and coldness of human relationships. All of this was tearing Wang Yuhan's already fragile heart apart all the time. At this time, only his mother's deep maternal love could make Wang Yuhan feel a little warm. In the end, Wang Yuhan left the family, left home, and decided to embark on the path of a strong man. Because he had no money at the beginning of the period, he even had a sudden idea to resell cigarettes from his previous life in a strange place called Tianhai Continent. Unexpectedly, he really made a fortune.
