Fifteen hundred years ago, an unparalleled expert emerged in the Lower Realm. He cultivated to a height that should have been impossible there, defied the heavens, and forced his way through a tribulation. That day, the sky split open with countless rays of rosy light. The waters of the four seas churned at once, the mountains shook, birds crashed into the peaks and died, and every beast bowed to the ground, wailing. He succeeded and ascended to the Upper Realm.
The Upper and Lower Realms had never been connected. When he left, he forced open a passage between them. The spiritual energy of this realm flowed through the passage into the Upper Realm, growing thinner and scarcer with every passing day. From then on, cultivation became harder and harder, and fewer and fewer people could sense spiritual energy. The Great Dao was incomplete, and the path of cultivation was severed.
Later generations cursed him as a sinner. His name was erased, and his teachings were burned away. Yet the sight of his ascension lives on in human memory to this day. The elders say it was the last time the Cangli Realm ever saw the heavens filled with spiritual light.
