Even at the time, Zhou Tian might have thought that the Human Emperor's current performance was the most normal! After all, in that battle situation, the only one slightly weaker than Zhou Tian was precisely that Human Emperor. Thus, it was normal for Zhou Tian to be killed by those Deities then, and if the Human Emperor had performed too outstandingly, it would have probably drawn Zhou Tian's attention.
Therefore, even though the opponent's action had caught Zhou Tian off guard, Zhou Tian still had to admit that the opponent indeed had the ability to plot against him. If they really wanted to scheme against him with all their might, Zhou Tian couldn't have escaped their plot.
