Chapter 644: The Old Man Who Walked Out of the Immortal's Tomb

This was the edge of the Immortal Domain, utterly desolate. The land stretched endlessly, with constant undulations, and not a single blade of grass grew on its surface. Looking around, there was not the slightest trace of life energy flowing, making it seem many times more desolate than the Frontier Wilderness of the Nine Heavens and Ten Earths.

This sight was very strange.

Though the area was abundant in Spiritual Energy and washed in Immortal Qi, filled with Holy Lands of Immortal Realms and excellent places for long cultivations, a place that everybody from the Nine Heavens and Ten Earths desperately wanted to enter, it gave off an impression that it wanted to extinguish all vitality.

On normal days, very few beings could reach this edge.

Even those proclaimed as Invincible Existences of the Supreme Realm could not, because it was too far, and moreover, with no way to live forever, even spending a lifetime would not suffice to reach this marginal land.
