Originally, when Qi Tian moved the ghost face's mouth to his own face, the ghost face was still struggling and challenging him. But after Qi Tian spoke these words, the ghost face immediately became silent, no longer as active as before, without any superfluous motion.
Qi Tian raised an eyebrow and said, "It seems you don't wish to cooperate with me, nor do you have any slightest intention to surrender to me. Have you considered the severe consequences of not accepting my recruitment, of not surrendering to me? I'll give you one last chance. Are you going to yield or not?"
The mouth of the ghost face remained motionless. Qi Tian could clearly feel that it was still sentient, not dead. This pretty much confirmed the ghost face's mouth was rejecting his offer.
