Xiao Jue inherits the divine power of Nüwa's lineage, born with heterochromia and words that manifest as reality. For centuries, she has kept a low profile, guarding the peace in all directions. Breaking her rule, she descends the mountain to visit her granddaughter Xiao Zhiyi, who has just given birth, only to be shocked to find that the person before her is an impostor. Tracking the clues, Xiao Jue uncovers the truth about the Fu family using the Xiao family's name to commit unlawful acts, and even entangles the conspiracy of the four major families of the capital—the true Zhiyi is imprisoned for possessing the heart that suppresses the veins, and the four major families attempt to seize the power of the dragon veins. Using her wisdom and divine power, Xiao Jue defeats the villains' conspiracy, rescues her granddaughter, resolves the dragon vein crisis, and makes the ungrateful face their just deserts. After this battle, Xiao Zhiyi grows into an independent guardian, and the grandmother-granddaughter duo shoulder-to-shoulder guard the common people.
