It wasn't just that the Corpse Demon itself was not as powerful as Zhou Tian, even if its strength was truly on par with Zhou Tian's, under the circumstances of being severely injured and having sealed its hidden trump card, it was destined to have no chance of victory.
Therefore, the moment the Corpse Demon resorted to its desperate measures in that situation, it had essentially admitted its 'defeat'.
Of course, no matter how the Corpse Demon reacted, Zhou Tian would not let it off easily. After all, the Corpse Demon had caused Zhou Tian quite some trouble before, forcing him to come up with new tactics. However, based on the Corpse Demon's actions and what they represented, Zhou Tian would undoubtedly not rest until it was dead!
