Chapter 397 opens with a description of the blue dragon. He explains that the lower worlds do not accept cultivators from the higher worlds because they are too strong. He also explains that he cannot find out about the white-brow taoist because he is not from the lower world. He suggests that they search for the xuanming caves, the immortal tombs of tianming and tianmin, and the east area. They will distribute dragon blood from his body to remove the effect of the blood sacrifices in the sea. The true dragon blood in his body is much more than this, he says. He asks the starfield kingdom crown prince, Lu zhuo, if he would like to join his team during the expedition to the secret realms. He says that he has already accepted the invitation of the prince of the dayu kingdom. Lu tianxing joins the team, and they set out for the secret realm.
