Let me recommend a novel for you called 'The Supreme Poison Woman: The Alluring Imperial Concubine Plays the Duke'. The female protagonist was cruel and cold. She was cultivated by a fox demon and was brought back to ancient times by time and space. Although her beauty was beautiful and had a vicious aura, when they first met, her ruthless aura turned into love for him. He was the ruler of a country. He spoke elegantly, but he could command the wind and clouds. As the ruler of a country, he only looked back for her. I recommend this novel because the female protagonist's ruthlessness and cruelty are very similar to the female protagonist in question. I hope you like my recommendation. Muah ~
