The Demon King's Pet Kingdom

Lord Demon King... If I think about it, I can't think of anything else: Cold, ruthless, killing all living beings... But who would want to become like that? There are no demons in the world. Those people with cold and serious faces are just not used to expressing themselves, and they just pursue the little dawn in their hearts. Who would want to become a demon? This is my first time writing. There are so many female protagonists. Well, there are so many. If you don't like it... Just don't like it. Anyway, it's just for myself. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
