In the midst of his martial arts training, the dragon king asks his son if he's doing well. The son says that he doesn't think he should worry about his father. He asks if the mercy palace and the dang clan will be allied with it. The dragon king says that they will only benefit from one another. He says that if the title of "greatest family in the world" were as simple as it sounds, then the title would have already been in his hand long ago. He also says that the people from the "mercy palace" will be coming shortly to make a revived corpse. The revived corpse is a method of turning people into undead. He tells his son that he can't do anything with his demonic aura because he has been hiding it all this time. He explains that they are going to use it to increase their energy circulation. The mercy palace kidnapped him, tried to kill him, and that night in hell haunts him every time he remembers it. He's going to kill all of them.
