Zhou Tian originally killed the Human Emperor every once in a while, and when facing Zhou Tian, aside from waiting to be slaughtered, the Human Emperor essentially had no strength to make any counterattack actions.
However, with the addition of those Deities into the Battle Situation, Zhou Tian no longer enjoyed those good days.
Zhou Tian was unkind to the Human Emperor, and after gaining an advantage in strength, directly applied strong suppression on the opponent. When the strength of the Human Emperor's side eventually surpassed Zhou Tian, they naturally wouldn't be polite to Zhou Tian either, and would not mind killing Zhou Tian a few times if the conditions allowed.
