However, these things were generally only suitable for human cultivators. Sea beasts lived in the sea. Even if they could transform into human forms and live in the sea, they couldn't move in the sea in human form, because it was more convenient for them to move in the sea in their original form.
The original forms of sea beasts were usually very large. If they were given the space-teleportation equipment of human beings, they would have no space to store those space-teleportation equipment after they transformed into their original forms. Therefore, Zhao Hai and his team created a space-teleportation equipment that could be adjusted in size. When they transformed into human forms, these space-teleportation equipment could shrink into rings, bracelets and the like and be worn by them. Then, the appearance of the space equipment would become bigger, and they would still be worn on their bodies. They would not fall off, which was more convenient.
