Lin Zhou, a young man who carries the golden bloodline of the Sword Immortal, finds his world thrown into chaos when the ancient seal on Qingfeng Mountain shatters, unleashing black-and-crimson demonic energy and letting vengeful spirits loose upon the land. To stop the coming catastrophe, Lin Zhou sets out to reforge the seal. Along the way he meets Shen Qingyan, a master of formation arrays; Lu Yan, a lone mystic burdened by his past; and Wen Tao, a kind-hearted soul driven by a sense of justice. Bound together by their beliefs, they stand against the forces of darkness, each confronting their own inner wounds and regrets, supporting one another through deadly perils as they grow—and fighting side by side to protect the peace of the world.
