There is no danger in the Secret Realm, and it is rich in spiritual energy, perfectly suited for the growth conditions of the Transformation Pill. Hence, over time, humans have no shortage of these pills. This is one of the reasons magic beasts do not resist forming contracts with humans; with a master, they need not worry about transformation.
Transforming into a human form is critically important for magic beasts, as it affects their potential to become stronger in the future. No matter how formidable the beast's physical body is, it must be admitted that humans are the spirit of all creatures. Only by cultivating with a human form can one better align with the operation of nature's spiritual energy.
