The celestial and demon realms stand irreconcilable. Ling Canglan, the ruthless God of War of the heavenly realm, keeps Feng Yao, the demon realm's abandoned princess with defective spiritual veins and subjected to endless humiliation, by his side. Decisive and ruthless to outsiders, he showers her alone with extreme pampering, defying the heavenly realm and sweeping away enemies for her. Deeply in love across the taboo of races, the two are pressured by the three realms. Choosing to sacrifice herself so as not to drag him down, he exhausts his lifetime of cultivation to save her. Feng Yao unexpectedly unlocks her dual celestial-demon constitution and is reborn through Nirvana. Ling Canglan abandons his status to follow her, defying the heavens to rewrite fate, forging a stunning love story that shakes the three realms.
