The butler tells the two young men that they are too young to enter the "bone- forging realm" . He tells them to hand over their elixir and secret recipe to him and he will let them go. They are afraid of the old man, but they will rather die than give him their family's secret recipe. The butler is surprised that the young men are so bold. He thinks they are "demon cultivators" who talk about mercy. The young men tell him they are going to attend the "elixir festival" in the city of flower rain. The headquarter of the "flower rain tower" will hold the festival every ten years. If they are lucky enough to be chosen, they will be welcomed as their family and protected by them.
