97 points of Spiritual Origin Ability were invested, raising the Flow Barrier to (Second Level 1/577).
Ji Xinghuo paused and noticed that the Second-Level Flow Barrier didn't look much different from the First Level, but its defense power had clearly increased. Then, he raised it to (Third Level 1/1777), and the formed energy armor was still a thin layer, only about one millimeter thick.
Only when the Flow Barrier was raised to (Fourth Level 1/7717) did it finally undergo a change.
The Ability had evolved!
From Superior Ability, it had evolved into a Transcendent Ability, yet it still remained at Fourth Level.
When Ji Xinghuo once again stimulated the Flow Barrier, he immediately sensed a curious reaction between his spiritual energy and this transparent, intangible armor. It was like a tangible electromagnetic field that, when attacked, instantly released a fine current in retaliation.
The seemingly fleeting current had not to be underestimated in its lethality.
