"Demon" is a legendary cultivator in Southeast Asia, because he got a very aggressive beast "Tianwei demon scorpion" when he was young. Although the Scorpion was killed by Xu Feng with one stroke, we should know how many cultivators the scorpion killed in Southeast Asia at that time and how many good leather bags were collected for the "demon" to refine bitter poison.

the stronger the leather bag is, the stronger the poison will be. It is just like the "black drug" that was just used by the "demon". It killed a two star king of China and took his leather bag before it was successfully refined.

"black drug control"...
