Now that Cai Ming is gone, the group has no choice but to continue walking. They're going to find their way to the "land of ancestral rocks" , and they don't want to be separated from each other. The narrator explains that the wind-extinguishing valley is the place where he needs to record the rules of the thunder. He's so close to mastering the rules that he has to hurry up and find the power to record it. He compares the thunder stele to a snake crawling up at lightning's speed. Cai Ming has been learning the thunder rules for a few days now, and he's even faster than the narrator.
