Lightning Speed Progress

Nightmare realm's desolate mountain range. 

A few meters above the mountain range, just barely out of the range of the miasma mist, three figures could be seen assimilated into a cultivation state.

Naturally, these three were Cain, Kali, and Amber. 

The trio was intently focused, completely ignoring everything from the outside world as they neared a critical breakthrough.

Two weeks have passed since the meeting with Qiao Tu. 

During this duration, Cain, Kali, and Amber were protected from suspicion because of Shi Wei's supposed close-door training.

And her reasoning indeed wasn't far off from the mark. 

Cain could certainly say because of Shi Wei, he had perfect guidance to blast through the Sky Ruler realm with the extraordinary help of the Nightmare realm.

Great changes had occurred within Cain's dantian.
