Haisha put her foot on the monster's head and gently kicked it away lest the corpse attracted other monsters to this place.
She then returned to the ice cave and looked at Dean worriedly. Although now the monster was dead, the poison had dissolved in the water, so Dean had to take the antidote before he could be submerged in the water. Previously, the monster was killed easily mainly because the poisoned water had penetrated into its wounds.
She paced back and forth and suddenly thought of something. She came to the waterside and washed her dagger, then came to the side of the ice bed and cut off a few pieces of ice.
She stuffed a piece of ice into her mouth and melted it into water.
She kept the water in her mouth until it turned warm before she opened Dean's mouth and poured the water into his mouth, melting the frozen antidote pill inside his mouth.
