It must be said that the Ancient Powerful Being did indeed have the right to question Zhou Tian at that time, because Zhou Tian's actions had indeed caused him severe damage. Had he been confident in defeating Zhou Tian, he probably would have attacked Zhou Tian immediately upon revealing himself!
Even now, though the Ancient Powerful Being did not take action against Zhou Tian, from his incessant glaring at Zhou Tian, it was evident that he cared greatly about Zhou Tian having destroyed his residence.
Unfortunately for him, his angry stares could not cause any damage to Zhou Tian. So, no matter how the Ancient Powerful Being glared at him, Zhou Tian simply ignored him nonchalantly. From this situation, it was clear that Zhou Tian did not take the Ancient Powerful Being seriously.
