Legend had it that the Qinling Mountains contained two Treasure Lands: one was the Transformation Immortal Pool, and the other was the Eternal Dragon Lair. There was a saying in the world that obtaining either one would allow a person to prove the Dao.
The origins of the Transformation Immortal Pool were mysterious beyond explanation. No one knew what had happened there from ancient times until now. Immortal treasures had sunk into it, shocking all who heard of them, yet remaining beyond anyone's reach.
Before the Primordial Age, an unparalleled battle might have taken place there. It was even possible that gods had been born there. Supreme Emperor weapons had been shattered and fallen into the Transformation Immortal Pool.
Beginningless Great Emperor had found a Chaos Stone in the pool and refined the immortal substance within it, forging the Beginningless Emperor Bell. When the bell rang, all eternity trembled, and its might was peerless.
The Azure Emperor had originally been a green lotus born here, taking root atop the Green Copper Chunk and gaining tremendous benefits from it. However, before he took human form, the Green Copper Chunk was lost and departed from him.
The Transformation Immortal Pool was so miraculous, and the Qinling Dragon Lair could be mentioned alongside it, so it was naturally extraordinary as well. It was nearly the strongest dragon lair in the Central Plains. This place was said to allow one to become a Corpse-Releasing Immortal, which was why so many ancient tombs lay beneath the earth.
After their deaths, many great figures would be buried here. Everything stemmed from that Eternal Dragon Lair. Everyone wanted to be buried inside it, hoping that one day they could become corpse immortals, exist forever in the Mortal Realm, and remain eternally imperishable.
