In the middle of the night, the young boy hears someone calling out for help. He goes outside to search for his sister, but no one is there. He begs his father to come with him and save his sister. He tells his sister that he has just been released from the dungeon and that he is now a member of the Qingyun sect. He also tells her that his neighbors have told him that chenshan has taken his sister and plans to sell her in the black market. He asks his father if he can repay him for the money he has saved so far, but his father tells him that he must focus on cultivating in the future. He warns his sister about the possibility of a black market at night, as the city has existed for over a hundred years. The black market allows anyone with enough money to buy whatever they want, including medicine pills and forbidden magical weapons.
