Nangong Taoyao is a renowned ancient demon god of the Demon Realm, cold and ruthless, born without the capacity for love. Murong Zhuohua, a newly risen Divine Emperor of the God Realm, falls in love with Taoyao at first sight during a banquet, and his feelings take root from that moment on. Taoyao, however, pays no heed to his secret watchfulness. Hoping to let the woman he loves experience the depth of mortal devotion, Zhuohua makes a shocking decision: he spends his own Genshin Impact to borrow a System from the Principal God, then ventures into three thousand small worlds, hoping Taoyao can complete missions there and obtain fragments of her capacity for love. Taoyao initially disdains this sudden arrangement, but in the end, she cannot resist the faint stirrings in her heart, stirred by Zhuohua’s deep devotion, and agrees to enter the unknown worlds. Thus begins a romantic and fantastical tale of love spanning the realms of gods and demons and journeying through three thousand small worlds.
