What’s So Great About Being a Demon King?

After using a cheat tool to successfully conquer female NPCs in the game who were never meant to be interacted with, Bai Zhen brought the World-Ender Dragon, the human princess, the elf princess, the temple's holy maiden, the Ancestor of the Night, and others into his harem... But after transmigrating into the game he had already beaten, Bai Zhen discovered that all the characters he had once conquered had returned to their original identities and no longer recognized him.

"Then I'll conquer you all again. This time, I'll make sure to burn my mark into your minds!"

With rebuilding his harem as his goal, Bai Zhen sets out once more to conquer every female character.
