On the fragile boundary between the Ye Luoli fairy realm and the human world, "Entropy Blight" spreads like a shadow, polluting water sources and snuffing out flames, threatening all life.
Wang Mo, a human warrior with the power of fire, forms a special bond with the Water Prince, Shui Qingli, guardian of the Lake of Pure Water, in the face of this threat. Kind and brave, she has unknown potential hidden within her fiery power. He is powerful and aloof, burdened with maintaining the water cycle, yet Wang Mo reshapes his understanding of what it means to protect.
From hidden currents in the human world to a crisis at the heart of the fairy realm, they face the Entropy Blight together. They endure the Trial of Sacred Water and the pain of merging their powers, searching for the truth among fragments of an ancient oath and mysterious clues: in ancient times, the spirits of water and fire guarded the balance together, and the shattering of their vow brought about the Entropy Blight.
The threat of Mandola, the Lake of Pure Water’s lament, and the confusion of awakening powers strike at them again and again. At last, in a ritual at the world’s core, they use love and protection as their guide, bringing water and fire into perfect harmony to cleanse the Entropy Blight and heal the scars.
As the tides and flames forge their vow anew, the fairy realm and the human world are reborn. And Wang Mo and the Water Prince’s story continues amid hopes of coexistence and mutual prosperity, awaiting the next unknown challenge...
