Anyone who has traveled through time knows that he suddenly traveled across time without knowing that day, and Xu Xian is one of the many time travellers.
Xu Xian traveled back in time to a five-year-old child. When he was six years old, he awakened from the system and was told that his time-travel was caused by the system recognizing the wrong person. Xu Xian used this to demand compensation from the system and start his fantasy journey.
Note: There is no heroine but there is a heroine because Xu Xian will become her. More than one world.
