The Emperor, who was sent by the Weiyang Dao Domain to capture the Weiyang Turtle that destroyed the Saint, was restricted by the Eternal Great Realm and became the companion turtle of the Eternal Mother. He lost his memory and turtle shell (that is, Bai Xiaochun's turtle-patterned pot), and his strength was at the peak of the Dominator.
