In ancient times, the battle between humans and demons. Thirteen powerful human beings sacrificed their blood to the Prison Suppression Tower, sealed the demon clan in the well of oblivion, and refined the tower's spiritual slaves to guard the barrier. This move brought three thousand years of peace to the human world. Three thousand years later, the life lamps of the spiritual slaves are extinguished one after another, and troubled times are about to arise. A young man is burdened with demon fire and inherits the Soul Sword Sect. During this time of chaos, he steps into this bizarre and bizarre world, practices swordsmanship, and becomes the best in the world.
