Nangong Taoyao, a famous ancient demon god in the demon world, is cold and ruthless, and is born with a lack of love. Murong Zhuohua, the newly promoted God Emperor in the God Realm, fell in love with Tao Yao at first sight during a banquet, and their love has been deeply rooted ever since. However, Taoyao didn't care about his secret prying. In order to allow her beloved to experience the deepest love in the world, Zhuohua made an astonishing move - he spent his own money on the original god, borrowed the system from the main god, and joined the three thousand small worlds, hoping that Taoyao could complete the task in it and obtain the love root fragment. Faced with this sudden arrangement, Tao Yao originally dismissed it, but in the end she couldn't resist the ripples of Zhuo Hua's deep love in her heart and agreed to step into this unknown little world of three thousand. A romantic and fantastic emotional legend that spans the worlds of gods and demons and travels through three thousand small worlds begins here.
