Pregnant Woman Unable to Escape from Water Prison

I'm pregnant with the villain's child. Originally, he just wanted to kill me after having enough fun. I don't understand why the child in my belly suddenly changed gender. But I don't want to live an ignoble existence. I want to kill him and the evil seed in my belly. That day, he held my chin with a fierce look in his eyes: "Don't play any tricks under my eyes, unless you want to die!" I chuckled and stared at him, with only contempt in my eyes: "Really, I can't ask for anything."
