The true gods with powerful strength were the last to retreat. Zhou Tian, though he hated them to the core, would not choose such targets. Therefore, although he had made up his mind to use those tactics to take revenge on the enemies, the ones he could deal with were only those Divine City forces that retreated first.
Without a doubt, unless Zhou Tian died under the chase and kill of those Divine Cities, otherwise based on Zhou Tian's character and experiences, he would take revenge on them. Those Divine City forces had long been mentally prepared for this.
Since he had not received any news of Zhou Tian's death, although not certain that Zhou Tian would strike at them, those true gods who had withdrawn first would definitely take some defensive measures against the potential retribution from Zhou Tian. Thus, as Zhou Tian had not deliberately hidden his movements, with the tactics of those true gods, it was no surprise they could learn of Zhou Tian's arrival at the first moment.
