Yunzhong Jun and Star Wraith discuss their problem of Lady Yueshen and her close ties with the Eastern Emperor. Yunzhong Jun proposes using a Spirit Soul Pill which numbs the body when exposed to heat but Star Wraith suspects that Lady Yueshen will detect it and become suspicious. The three children overhear them talking and realize that Yunzhong Jun and the Yin Yang school were responsible for the death of the former Mohist leader, Six-Fingered Black Hero. Yunzhong Jun agrees to continue observing Lady Yueshen while Star Wraith will try to get more information about Qianlong (Yue-er). After they leave, the three children continue their search for the Cloud Sky Pavilion and enter a room with a nine-headed machinery snake (Nine-Headed Gouyu). Fearing a trap they come across a large medicine cabinet with many drawers. Using a partial code inscribed on it by Shi Lan’s brother and Tianming’s knowledge of puzzles they manage to disable the mechanical snake guardian by opening the drawers in a particular sequence. They retrieve a Pure Dredging Pill to counteract the effect of the paralyzing needles on Tianming. As they are about to leave, Yunzhong Jun returns suspecting intruders.
