In the middle of the night, the first test is to be carried out. The six groups will enter the cave in front, and ten people will be allowed to pass through. Everyone in the first group is an elite member of each family. When the test is over, the last group enters the cave. The noise is so loud that helan loses consciousness while standing. Helan is worried that the sound has a hypnotic effect. The last group is the most dangerous, because they are afraid of the "baiyue sect" . They would rather kill one person than thousands, helan says. When he asks what is wrong, he is told that his uncle said the test would be to kill those who were related to the "xuanmen sect" and the "grand demonic race." Helan wonders if his uncle means to kill Zhehao wu, and wonders if he could have killed her. The sound of the underground cave is heard.
