The Human Emperor's decision was absolutely without fault, given his situation at the time, making such a decision was absolutely the right one.
However, even though the Human Emperor's choice was not wrong, his actions at the time undoubtedly deeply offended Zhou Tian. After all, at this moment, Zhou Tian wanted to take some action but encountered such significant resistance in his domain, it was clear to anyone thinking about it that Zhou Tian would surely hold a grudge against the Human Emperor who blocked his actions back then.
Originally, both parties were already enemies, and because of the Human Emperor's actions, Zhou Tian was further offended. Given the circumstances at the time, how could Zhou Tian possibly not take some action?
Since the Human Emperor had that kind of response, Zhou Tian naturally could only engage in combat with him.
