Ku Mu mountain, rather than a mountain, it looked more like a giant dead wooden tree that extended into the clouds.
The name of the wood was old earth.
Old earth wood had a long lifespan, this particular pillar of old earth wood had more than a million years of history. From Reckless Savage Demon Venerable's era, to Red Lotus Demon Venerable, Genesis Lotus Immortal Venerable, Thieving Heaven Demon Venerable, Giant Sun Immortal Venerable, and then to Spectral Soul Demon Venerable and Paradise Earth Immortal Venerable. Even after Paradise Earth Immortal Venerable died, it was still alive.
When it had lush leaves, the greenery covered the entire sky, and it produced countless fresh fruits. On its strong branches, unique tree farms could be created.
During its golden years, it was usually owned by the strongest Gu Immortals or the most powerful forces in Northern Plains.
