Chaos Divine Artifact, in the eyes of the Transcendent Level Civilization, is essentially the embryo of a Supreme Treasure. Because Chaos possesses infinite possibilities, it has the opportunity to evolve into a Cosmic Treasure.
Thus—
Cosmic Treasure can be said to be a Divine Artifact surpassing Chaos Divine Artifact, but it contains far more wondrous powers and might beyond what Chaos Divine Artifacts contain!
It's important to know that a Void Divine Positioner only needs genes at the level of the Cosmic Limit, coupled with a Chaos Divine Artifact that has been cultivated to its limit, almost evolving into a Cosmic Treasure, to achieve the Cosmic Upper Limit.
Like that Immortal Realm Chaos Son.
Although possessing Supreme Secret Techniques and also his Lifebound half-step Cosmic Treasure, the main reason is due to genes beyond the Cosmic Limit, allowing him to touch the Cosmic Upper Limit in terms of power.
However, that's the upper limit.
