In the desperate situation of the iron mine pit in the Middle Earth, the deadwood-level mine slave Li accidentally awakened a taboo living blade from the Soul-Eating Sword Abyss of the North. The evil sword devoured his soul and fed him back, giving him twisted power, but it also crazily eroded his sanity. In order to escape the pursuit in the mines and the "Clean Sword Burning" in Middle-earth, Li took this ominous blade and broke into the Soul-Eating Sword Abyss, the hometown of the Living Blade. In the abyss, sword-skeleton monsters and greedy hunters are waiting around, and they are even hunted across domains by the high-tech "scavenger" troops of the Crystal Core Sword Domain. On the verge of death, deep in the Tomb of Ten Thousand Swords, a dark gold giant sword that had been silent for eternity and was full of cracks awakened. Its desolate will frightened away the monitors of the abyss, frightened the powerful enemies of the crystal core, and locked the dying Li as a key "key". Humble mining slaves, soul-eating evil swords, and ancient giant weapons intertwined in the Living Blade Cemetery, tearing apart the dead silence and unveiling the turbulent era and final secrets of the Sword Ruins world.
