The Zhenyue Sword has been passed down from generation to generation by the Zeng family, but behind the glory lies the horrific truth of blood sacrifice. On the day when the young family head Zeng Lie succeeded to the throne, the sword spirit whispered "the sacrifice is good", and his grandfather died suddenly, revealing before his death that "the sword is eating people". Breaking into the blood pool in the forbidden area, he saw the skeleton of his father, with the bloody last words carved on his wrist: "Run away - don't believe your mother!"
The mother's cold gaze became the prelude to the pursuit. On the way to escape, Zeng Lie discovered that Zhenyue Daoling was also a prisoner distorted by evil laws. With guidance carved in the mountains and enlightened by saints, he awakened the false sacrificial fire beside the lava in the Yan Valley and regained a glimmer of hope. The incomplete inheritance of the fire keeper marks the soul, the golden lotus moss of the earth's veins heals the wounded body, and the immortal moss in the ashes and desperate situation protects the soul.
