The dark void can't absorb the soul Qi or anything related to the soul, and Ace didn't put all this hope on the cracked gray boulder either.
'Soul Barrier!'
Ace quickly activate the first skill of soul guardian barrier art, the soul barrier!
A vast amount of orange soul Qi started to emit from his orange soul core and like a thin translucent film, the orange Soul Qi started to cover Ace's true soul (mind space) and completely shrouded it. This was the soul barrier in low-level mastery, but it can still protect him from Flowing Soul River cultivator soul attacks.
However, can it protect him from the Heavenly Soul Thunder? Well, he was about to find out.
The two translucent sword blades landed on the gray boulder first, since it was right above Ace.
