According to the situation at that time, theoretically, what Zhou Tian did would only offend the True God of that Divine City, and as long as he did not confront the other party, his robbery of that Divine City would have no aftermath.
However, if Zhou Tian truly intended to make robbery his occupation, then everything would be different. Once Zhou Tian truly left the impression on other Deities that 'he is a robber,' it is estimated that he would be intercepted by other True Gods wherever he went.
Deities are selfish, and under normal circumstances, one shouldn't expect them to risk their lives for others. However, generally speaking, those Deities won't take action against Zhou Tian for another True God. But once they believe Zhou Tian would rob their Divine Cities, in the situation where their benefits would be damaged, those True Gods would not care how powerful Zhou Tian is and would regard him as an enemy at the first instance.
