In this chapter, the ghoul explains that he has been unable to live with humans for the last ten years, and that he needs to save his mother. He needs a week's time to prepare for his return to the human world. He tells the humans that they can visit his mother in the future, and asks them to enter the world immediately. The ghoul says that he would like to explore by himself, but that he is being sent to the world to deal with something urgent. He says he will look for the humans when he returns, and tells them to get acquainted with him. He is the leader of the federation's "top killer union" , and he is looking forward to collaborating with the human ghoul. The copper column tells him that the monsters have gone missing from the mystic clouds, and the humans are keeping close watch. They originally planned to attack the humans after the annual testing, but this seems like a good opportunity for them to make a decisive battle against the monsters. He explains that in the past, the humans could have killed small monsters to gradually increase their strength, but in the new world, they must have gone to bully the weaker monsters. The human race has discovered the martial world and seen through the monsters tricks, and there is bound to be a large scale battle.
