Huang Yanshan studied the map and listened to Gu Shanhai's words, memorizing everything silently in his heart. After Gu Shanhai finished speaking, he then inquired, "This must be one of the ingredients for the Nine Grasses Pill that uncle intends to refine, as rumored in the martial arts world?"
Master Lu's pill-refining endeavor of the Nine Grasses Pill had naturally set the martial arts world abuzz, with various rumors and claims about its effects.
"Yes, that's right," Gu Shanhai didn't outright deny it.
"With so many precious natural treasures used to create the pill, what effects does it have?" Huang Yanshan asked with a hint of curiosity.
"It's of no use to you; mainly it serves to muddy the waters," Gu Shanhai said without going into detail.
However, Huang Yanshan suddenly became serious. To muddy the waters was indeed to fish in troubled waters. They were no match for a Martial Arts True Immortal, so they had no choice but to resort to different tactics.
