In the fourth floor of the netherworld, the flames are hotter than ever, and the group of people are gathered there. One of them is not there, but he will try to climb the fifth floor, and he and his sister will also try, but they will be unable to reach the top. The group is worried that the evil man will be able to climb all the way to the top, and they are afraid that his soul will burn if he does not stop. They are also afraid that the black flames will burn their soul if they do not stop, and so they ask the goddess to help them. The goddess tells them the story of the black tower, which was once occupied by two scholars who were experts in the sacred realm of the boundless profound. The scholars were older than nine and they fought six times, but one of them was killed and the other disappeared. They left behind the black inner tower, the treasure that they had stolen, and left the rest of the world in a blazing inferno. The tower was also used as a training ground by some spiritual gods, who locked the beast in it. The two scholars were disciples of Emperor Kong Ming, fighting for the unbounded profound.
