When chaos first emerged, Pangu's Sky-Opening Ax created three domains and nine realms. Each of the twelve ancestral witches controlled the original laws, leaving only the "Chaos Soul Vein" as the key to rewriting the way of heaven. One hundred thousand years later, cracks appeared on the heavenly chessboard of the divine world. On the star map representing the mortal world, the light of twelve soul veins was condensing into the shimmering light of chaos in Su Han's body. This was a sign of the awakening of the bloodline of the ancestral witch and a prophecy of the breaking of the seal of the original demon. On the night of the lunar eclipse in the Starfall Valley, the boy who was exiled by his family held the engraved pendant tightly, unaware that he was about to awaken the chaotic soul vein that could accommodate all kinds of magic. He also didn't know that the so-called "thin bloodline" was actually a seal set by the ancient ancestral witch to avoid the backlash of the heavenly way. At the same time, the bloody altar of the spiritual world devoured the law, the seal of the divine world was loosened, and the third eye of the original demon locked on this chaotic chess piece.
When the blade of chaos split open the darkness of the Starfall Valley, and when the shadow of the ancestral witch shattered the cracks in the Nine Netherworld, the balance of the three realms began to collapse. Su Han rises in betrayal and awakening, and will eventually find that he is both a pawn on the chessboard of heaven and a chess player - the resonance of the twelve soul veins and the bloodline of the ancestral witch will determine whether the world will return to the grand scene of the opening of heaven, or fall into the abyss of the demonic realm.
