After a sudden death, the soul did not enter the "above heaven" reincarnation as usual. Instead, due to obsession (complaining about the unreasonable plot), it merged with a broken ancient book that recorded the secrets of the world. It accidentally retained the memory and was reborn as a down-and-out aristocratic son of a low-level martial world in the third "world". The original owner failed in the fight for family inheritance and was poisoned by his brother. Mo Chen's soul took over when he was about to die.
