In the eyes of all people, the world is divided into two parts. One part is the practitioners, whose number is less than one million, and the vast majority of them are mortals with tens of millions of people. Mortals are too fast to bear and too fast to die. Sometimes the practitioners have been shut up for more than ten years. After they come out, there is no change in the practice world. However, things and people have changed. The vicissitudes of the world have changed. Many young men and girls who want to be concubines or face leaders some time ago will soon become parents in law.
