Du bai is the first to notice that the monster is approaching, and he tells the others that they should divide the harvest of the day's monsters equally when they return. They continue on their journey, and chengzi asks about the combat experience of the kid. He doesn't know where the kid came from. The three of them watch the night, and little tang shows them how to use the ice dagger. The trick is to increase the dagger's speed. He explains that the aura of the dagger changes instantly, and even his scalp feels tingling. He tells the group that they must try to achieve the "triumvirate of spirit , energy and essence" to make the opponent's attack impossible. He says that he will start practicing tonight, and that he'll tell the others more about it later. Du Bai asks if he can give him some advice about practicing time change. He suggests that they practice consuming their spiritual power. This will help them improve their time change, and Du Bai agrees to try this too.
