Plotline
Hexi gave Xi Jia and the other ten people three tasks in order to assess them.

They could only leave Burning Heaven, Ice and Snow, and Desolate Desert Realm after they finished cultivating and went through the trial.

And if they passed the trial and achieved Foundation Establishment stage, Xi Jia and the others could began to cultivate Demonic Terminating Method.

If Xi Jia and the others were able to achieve the Earthly Demon Gold Body stage (equivalent to the cultivation of the summit of Gold Core stage), they could be considered to have the utmost capability to protect themselves in Mi Luo Continent.
