In this chapter, we are introduced to the master swordsman of the mountain called "Qingming" , who has killed countless demons. He has been promoted to the rank of the best swordsman in the entire generation of monks. He is also known as "bai qiuran," which means "teacher." He is the only disciple of the master who is not able to build his own foundation. The master is worried that his apprentice will not be able to do so, so he gives him the red robe to wear. In this way, the master is not concerned about his apprentice's lack of foundation. This is the "memory lens," in which the master secretly looks at his apprentice who is practicing and tries to figure out if the apprentice is capable of building his foundation. In addition, the third brother has already passed a hundred years, and the sisters in the sect have grown to be beautiful. Why don't they go out together, and understand each other better, if they just focus on cultivating, and not on the "messy things" all day long? The master goes out to kill demons. The third brother agrees to go out with the master, but he doesn't want to go with his sister because he thinks that he will be unable to build up his foundation since there are only nine layers of qi refining in ancient times. In order to achieve this goal, he decides to make a "breakthrough" on the night of the moon and the earth's meeting.
