Just as those true Gods thought at the time, although Zhou Tian suffered significant losses because of them, due to Zhou Tian's lack of strength, he indeed didn't have the ability to retaliate against them.
Of course, Zhou Tian certainly didn't have the ability to directly seek revenge against those true Gods. Not to mention that the power in their hands is not weaker than Zhou Tian's; even with the help of his subordinates, depending on the strength of those divine city true Gods, the most Zhou Tian could do is defeat them. With his current strength at the early stage of a true God, it is simply impossible for him to kill those true Gods.
However, while directly seeking revenge and planning to kill those true Gods seemed impossible for Zhou Tian, if Zhou Tian didn't have the intention to kill them and just wanted to seek revenge, it was still possible.
After all, ultimately, it's because Zhou Tian often did such things that he drew those true Gods to jointly attack him.
