The power that came crashing down on the old man made his expression change. He was knocked out flying and after some distance tried to stabilize himself.
But the look on the old man's face was that of astonishment and fear, his bones had cracked in several areas, and internal injuries on this one collision woke him up. He seemed to have realized that continuing like this would become disastrous to him. This was all true especially after seeing that Wang seemed intact from their collision and her control of power was improving through the fights.
When this all is happening Wang did not meddle but kept watching and couldn't help but admire her a little.
When the words a genius are mentioned, the perfect picture that comes to his mind is Ruruo.
Back then she was also attracted to his speed of cultivation, but she thought he was hiding cultivation at the time but she realized it was not the case.
