The transmigrator Liu Xuan arrived in another world with the Heavenly Emperor System, only to become a low-ranking god with no worshippers, on the verge of starving to death. Just then, on a mountain altar, a girl was sacrificed to Nema, the sun god, in a plea for rain. The girl's lingering soul drifted into Liu Xuan's divine domain. Using a blue chi-dragon's spirit as the foundation and a mortal soul as the catalyst, he shaped her into a new being and named her Hua Lin, meaning Flower Rain. "Hua" was inspired by the radiant blossoms in the Book of Odes poem "Peach Tree, Graceful and Fair," while "Lin" means sweet rain that falls for three days and nourishes all things, as in the Book of Odes poem "Fields of Fu." Together, the name means rain, and she became the goddess who governs it.
Thus began Liu Xuan's path to creating gods. He combined the essence of divine beasts with mortal souls: Qingluan Xichun, who governs spring, takes her name from "may all undertakings flourish" in the Book of Documents and "spring is the green yang" in the Erya; Sibuxiang Taihe, who governs balance, draws on the meaning of "preserve and unite the Great Harmony, and all will be favorable and correct" from the Commentary on the Judgment of the Qian Hexagram in the Book of Changes; Errshou Wuyou, who governs lies, takes her name from the fictional words of "Mr. Wuyou" in the Rhapsody on the Imperial Park; Nian Shou Muyao, who governs the year's end, draws on a Liang-dynasty text by Emperor Yuan describing the twelfth month as the final winter month, also known as late winter or the end of winter; and Bai Chi Xianning, who governs clouds, takes her name from the definitions "fine" and "to gather," describing delicate clouds coalescing in the sky.
Facing the old gods who fed on humans, Nema, Dawa, Longcu, Riju, and the rest of the evil gods, Liu Xuan sounded the call to war: "The old gods feed on people. The new gods draw power from wishes. The age of you eating people is over."
