As long as Zhou Tian managed to endure those Divine Kings' attacks back then, then based on Zhou Tian's Strength, once he launched a Counterattack he would be able to wipe out that group of Divine Kings; no matter how you looked at it, that absolutely wouldn't be an impossible thing. And once that situation appeared, Zhou Tian's goal would basically be considered achieved.
For Zhou Tian, those Divine Kings were, in any case, an enormous Threat to him. So given the situation at the time, if Zhou Tian could, through corresponding Tactics, wipe out that group of Divine Kings, then for him it would also count as eliminating a Threat lurking in the shadows. On top of that, killing those Divine Kings back then would be of immense Help to Zhou Tian's future war against the Divine Realm, so if something like that really had a chance to happen, Zhou Tian would definitely do it.
