[Divine Throne] All I Ask Is One Night with the Demon God Emperor

Short version: A woman who transmigrates has two lifelong wishes: sleep with her dream guy, and find all sorts of ways to sleep with him. Her dream guy has two lifelong wishes: become a god, and make the demon race prosper. When these two meet... Transmigrator: “Dream guy, let's make each other's wishes come true! Wanna?” (*/ω\*) Feng Xiu: “...Sure!” Full version: A die-hard fan of the Demon God Emperor, a young woman transmigrates one day, only to discover that she's gone a little too far back in time. Stranded in ancient times, when even the glorious Church of Light has only just been founded, the transmigrator declares with conviction: “I'll do whatever it takes to sleep with my dream guy tens of thousands of years from now! I won't rest until I do! I swear I won't reincarnate!!” Her target, His Majesty the Demon God Emperor, has two lifelong wishes. His personal ambition is to become a god; his career ambition is to make the demon race flourish. To achieve both, His Majesty sets off on a quest to Dream Paradise to seize a divine spark. However... When faced with a little girl wearing an adorable smile but saying something as filthy as, “Let me do you.” His Majesty declares: “There must be something wrong with the way I'm trying to obtain this divine spark!”
