Demoness Zexi

This Astral Demon casually looked down on Cain and said, "Refer to me as general Wen. Hurry it up and get to mining at this section." 

The Tao siblings didn't need any prompting as they quickly scurried along to their mining section. 

Cain silently followed general Wen's direction, picked up the dingy pickaxe near his feet, and got straight down to work. 

Up close, Cain suddenly detected something strange from these divine purply crystals. A faint, yet noticeable calling stirred in his blood and soul. 

Without any change in expression, Cain chopped down his dingy pickaxe at a random purple crystal. The moment it connected, the mystical energy from the divine purple crystal directly flowed into Cain's body. 

Cain expected something. A fierce burning pain. Terrifying cold. Or even a jolt of painful electricity. 

However, no pain had actually come to him!
