The Hunt Family and The Cure

As Rickston mentioned, the heart inside the ice crystal belonged to an ice-breathing dragon that lived in the treacherous ocean. It was the last of his kind. After the war between beastmen and the dragons, as well as the dragon clan's sudden disappearance, only a few dragons lived in the treacherous ocean. The ice-breathing dragon was one of them. The dragon's coldness could shatter even a Fusion stage cultivator's body. Since it lived in a treacherous ocean, none dared to bother the dragon until a brave adventurer managed to collect a few body parts of the dragon. As soon as Michael heard Rickston, he desired to get the heart for Nightmare. He could think of a few potions that could use the dragon's heart as an ingredient to give Nightmare a new ability. However, he doubted he could get his hands on the dragon's heart.
