Cheng Wei just made a sudden wish to go back to the past in the Earth Temple on the mountain. When he woke up the next day, he found that he had really gone back to the past, and he had changed from a boy to a girl. In fact, it was just a whim, but the reality told him that he had really entered a parallel world in which only he had changed. Now that he has returned to the past, he decided to study hard this time and start his life over again.
