I recommend "The Demon Lord She Transmigrinated From the Kingdom of the Female Venerables". This is an ancient romance novel. The female protagonist was the heir to the throne of the Female Venerable Kingdom in her previous life. In this life, she became the Demon Venerable of Hell's Palace and achieved the supreme realm. In the novel, the female protagonist became the underground king and met the mysterious King of War God. The two of them fell in love and killed each other. Together, they wrote a song that would be handed down from generation to generation. The reason for the recommendation was that the female lead was the king, and she had military elements. At the same time, she also had the characteristics of a transmigration and female character, which was very eye-catching. I hope you like this fairy's recommendation. Muah ~😗
