In this chapter, we learn that the Heaven crystal stone has fallen from heaven, and that the elder man has gone to the mountains to find it. The elder man is in danger of being poisoned by a green snake, and the crystal stone is the only thing that can rid him of it. In the evening, there are many different kinds of spiritual materials, but it is hard to find one that is perfectly complementary to the other. This is why it is so important to detoxify the grandfather's body. The heaven crystal is the core of a formation that can defeat demon worms. The water in the crystal is not flowing properly, and if it continues, the grandfather will die of thirst at once. He wonders if he can use the sky to devour the demon worms, or if he might be able to find the queen by the crystal.
