Mingguang Dust still remembered when Xuang Guangyun first brought him to the Endless Heavens on that contemptible, overcast day.
The Medicine Slave Worm Land of the True Demon Sect was located in a basin right in the middle of a gloomy mountain range, where even at noon, the sunlight was but an insignificant white speck.
A thick demonic poisonous fog ascended as black, grayish poison clouds covering the sky and sun, enveloping the entire area like a cage.
In that twisted and bizarre basin, it was filled with various terrifying demons and monstrously evil creatures leftover from ancient catastrophic times, their carcasses piling up into a unique ecosystem.
Every crack, cave, and pile of bones might conceal crimson, greedy eyes flashing; poisonous insects and miasma filled every corner.
The True Demon Sect tossed humans, demons, and worms together in there.
They didn't care what came out alive, as long as it was something they desired.
