When the abyss opened and the gods fell, Ye Jin was betrayed by his loved ones, lost all his power, and became a remnant soul in the ruins. Just when he was about to be annihilated, Si Lin, as silent as a knife, appeared from the darkness and used blood as a contract to drag him into the Abyss Throne. The two are not allies, but each other's curse and salvation - Ye Jin longs for revenge, while Si Lin just wants to swallow all the light. When the forbidden power awakens, they must choose between destruction and rebirth: should they fall into the eternal abyss together, or sacrifice each other to rebuild a new world?
