Sensing the seven ancient demons that were revolving around him, Su Zimo gained a semblance of realization.
There were already seven demon kings up till this point of his cultivation.
In other words, five more had yet to appear.
The limits of his cultivation of the Mystic Classic of the Twelve Demon Kings of the Great Wilderness should be when all twelve demon kings appeared!
Su Zimo did not know who were the other five demon kings.
In the mystic classic that Die Yue left him, the Yin Spirit section was a mystery.
Given his current cultivation realm, he could not understand it at all.
A blood-red Inner Core swiveled slowly within his chest.
Su Zimo could barely contain the joy in his eyes and merely gripped his fists gently. With every single action he took, he could sense the massive power coming from each part of his body that seemed to be able to crush mountains!
It was a leap in quality!
