The Flying Snow Serpent was the highest level boss near Huangqu Mountain. If they could eliminate it, it would definitely be a huge reputation boost for the Yellow Bend Gang, demonstrating their ownership of Huangqu Mountain.
Moreover, this serpent was guarding a treasure. Although the treasure wasn't top-ranked, two of the magical artifacts were essential to Don Quixote, the gang leader of the Yellow Bend Gang. So, they made up their mind to do this.
Seeing the Flying Snow Serpent overthrowing the three Du Tian Raging Fire Arrays, Don Quixote didn't care. He waved his hand, and his gang members replenished it promptly.
They had prepared for over a month to defeat this boss, using a substantial amount of resources, countless efforts, and, of course, expecting several difficulties.
The Yellow Bend Gang had as many as fifteen complete Du Tian Raging Fire Arrays, a significant advantage.
