I found a few recommended novels with the male protagonist being the Heavenly Emperor and the female protagonist being a transmigrator. Among them," Celestial Mountain of the Other World " described that the male protagonist Shangguan Wuxie was the son of the Heavenly Emperor before reincarnation, and the female protagonist was the princess of the Demon World before reincarnation. After reincarnation, she became the male protagonist's martial nephew and possessed mysterious abilities. In addition, Han Yin, the female protagonist of " Han Yin ", was the God of Justice of the Heaven Realm. She wanted revenge and sought revenge on the Celestial Emperor who had imprisoned her. These two novels are both fantasy and romance novels. I hope you will like them.
