This chapter opens with a flashback to the night before the battle. It is the night of the battle, and Cai Mingyu has been unconscious for three days. When he wakes up, he is grateful to have been able to save his life. He is also grateful to Cai Yunzhi for her kindness. He tells her that she has given him the armor of his sister , and he asks her to call him "yun zhi" the next day. She does so, and the next morning, she releases the contents of the armor from her mouth. The next day, she shows him the other armor, which is made of a metal from a blue whale's stomach. She tells him that the only person who can harm him is the dou emperor, who is the only one who has the power to crack whoosh. She also tells him to run away from the battle if he is in danger, because the cave is very hot. The cave is connected to the underneath magma, which means that the purple crystal is in the right place at the right time
