Daqian secret agent Lu Zhao lurked in the enemy country for ten years, but was framed by his best friend and buried alive in a battlefield grave. When dying, the 'eternal body' and the 'mountain and river system' are awakened, the corpse becomes the hub of the earth's veins, and the soul of the dead condenses into the city god's temple. He used his immortal body to gnaw through the earth's veins and reach the enemy's hinterland. He signed under the floor tiles of the Queen Mother's palace to obtain a fairy-level furnace. He transformed the enemy's capital into a corpse puppet production line and made envoys from various countries step on living workshops when they worshiped. The son of the blacksmith who impaled him in the past ascended the throne as emperor, but he did not know that the bronze cauldron pressed under the dragon chair was Lu Zhao's corpse-dissecting platform, which was delivering souls to the undead army in every morning court.
