πI recommend the following novel to you: " Evil King Courting His Wife: Hell Puppet Master " The female protagonist was the most cruel and cold-blooded killer in the Underworld. She was summoned to a foreign continent and met the male protagonist, who doted on her to the bone. He was domineering and black-bellied. He definitely met the requirements. [The Cold King's Attraction: The Fierce Concubine Obediently Enters the Urn] The male protagonist was a cold prince, and the female protagonist was a valiant princess. The male protagonist was pure in both body and mind, the male protagonist was black-bellied and powerful, and the female protagonist would not show weakness. They met the requirements. [Laughing at Light Dust] The female lead was direct and bold, while the male lead was infatuated and black-bellied. "Black-bellied Prince, surrender!" The female lead transmigrated into a concubine's daughter, the male lead was an ancient big bad wolf, the male lead was black-bellied and cunning, and the female lead did not show weakness. She met the requirements. I hope you like my recommendation.π
