However, what truly terrified everyone was not just this. It was the change in Wang Zhan's mental energy.
This might be what those previous Martial Kings meant when they said that once a mental energy secret technique is chosen, it can never be changed. This must be the root cause.
So much so that after Wang Zhan acquired the "Five Thunder Deity Refinement Method," received the fragments of the "General Outline of the Supreme Pure Thunder," and then completely restored this "General Outline of the Supreme Pure Thunder," even if he wanted to change and overcome it, the surging increase in his mental energy would not follow his will.
Naturally, it became exceedingly difficult to control.
It was like a raging torrent, destined sooner or later to wash him away until he was obliterated!
Furthermore, one mustn't forget that Wang Zhan's current realm was only that of a level 2 Martial General. Power acquired so easily naturally came with a price.
