In order to create a heavenly beast, a puppet must be made up of three parts: a body, a soul and a core. The core must be strong, the body must be healthy, and the soul must be nourished. In other words, the quality of a puppet is determined by its quality of soul, body, and core. In this case, the core is the most important thing, because it determines whether or not the puppet is made of heaven, earth, or earth and earth and heaven are the three grades of heaven. In order for the core to be strong and the body to be healthy , it must be able to hold its own against the other two. This is the case with the little medical fairy, who is trying to protect his friend from a poisonous flame. The little fairy is afraid that the flame will be too strong for his friend, so he seals the flame with his clothes.
