Based on Zhou Tian's performance at that time, if nothing unexpected happened, Zhou Tian would definitely have killed him. But obviously, although the Divine King was aware of his predicament, he had no intention of willingly letting Zhou Tian kill him.
Even ants seek to survive, let alone a Divine King!
Naturally, for the sake of his life, as long as there was a possibility of gaining vitality for himself, whether he was willing or not, that Divine King would surely act upon it.
As Zhou Tian looked like he had no intention of sparing him, the Divine King surely decided to flee at the first opportunity to save his life. Given the Divine King's power, in the face of typical danger, he should have had the ability to escape.
