The Dao-protector Dragon King could be big or small, flexible, invisible or visible. He had all the divine powers that the Dragon King had, and he also had abilities that the Dragon King did not.
Chen jingzhai could use it to perform divine powers, control it to fly, and even control it to fight enemies. It had a variety of functions, but the key was that its potential was not locked.
After cultivating the Dao protector Dragon King, Chen jingzhai sent the Dao protector Dragon King to the demon world and let the devil King feed it with demons.
Inside the Dao protector Dragon King's body, Chen jingzhai used a star core to create a concealed Dragon Pearl. It was the Dragon King's Own Dragon Pearl, one for life and one for death, yin and yang.
Not only could the Dragon King protect the Dao, but he could also refine demons. By devouring all kinds of demons, he could become stronger and use it to give birth to a new immortal spiritual light in his body.
