Although Zhou Tian knew that there were Deities chasing him, he believed that those Deities might not know him well. So, if the other side caught up to him, there might be a fight, but after the combat ended, those Deities' forces would probably not even know whom they were battling against.
So, although if Zhou Tian were to eliminate those Deities chasing him here, he would certainly offend a power in the Divine Realm. But if that power did not know who did it, then even if Zhou Tian's actions angered that power, it's likely they wouldn't know whom to retaliate against.
At the same time, even if that power were aware of Zhou Tian's information, it wouldn't necessarily mean they had the ability to retaliate against Zhou Tian.
