Super Grade Celestial Eye Doctor

Ye Yu's adventure from the sky made him travel to the Jiuli Realm. For eight hundred years, he practiced hard and made great progress, and finally became a generation of immortal emperors... Who would have expected that at the end of the three declines and nine disasters, the inner demon would actually come out of his body and become a demon. He thought he had died on the spot, but unexpectedly it brought him back to his previous life.
