Li Haojie, a young man in the 21st century, was disheartened after experiencing the sixth failure in his life. I bought a train ticket back to my hometown and wanted to see my parents who I hadn't seen in years. Looking at the bustling metropolis outside the train window, the scenes of the past are like slides, constantly emerging in front of you. Li Haojie was physically and mentally exhausted, only felt that his eyelids sank, and then fell asleep. When he woke up again, he found that he had been accidentally reborn into the body of a young man, and that there was a mysterious system in his body. Through the continuous growth of his knowledge, Li Haojie suddenly discovered that he had come to a world of immortal cultivation where you live and die.
