Five days later, North Pole Mountain in Luandu County.
Amidst the continuous mountains, a huge cave space was nestled inconspicuously under a low-lying hill.
The water in the cave flowed with a constant murmur, and the sharp stalactites on the ceiling scattered few but warm and luminous glow of bioluminescent algae, dispelling the darkness within.
At the center of the cave, there was a platform as large as two living rooms, where more than a dozen people with their faces covered by masks were gathered.
"I have ten Void Cloak Talismans, which allow one to walk on air at the speed of two horses, with each one able to cover at least a hundred miles. I'll trade them for six pieces of White Jade, or four bottles of Fasting Pills," a tall figure wearing a red ghost mask spoke up.
"Give them to me; I'll give you two bottles of Fasting Pills and two hundred jin of Yellow Bud Rice, how about it?" A skinny old man with a monkey mask was the first to respond.
