In the middle of the night, a strange sound is heard outside the master's bedroom. It's the sound of an alchemist's flame-control device. The alchemist is trying to figure out how to make the potion. He's worried that the potion will cost too much and that he'll have to buy more ingredients in the future. The voice of the father interrupts him and tells him that he can't worry because he's at the seventh stage of the clan. The father tells him to get started.
