This Is Bad! The Yandere Demon Venerable Insists on Having My Babies

[Two powerful leads + punishing scumbags + pocket dimension + doting romance + transmigration and rebirth] She is a genius in ancient martial arts whose soul came from the 22nd century. He is the Demon Lord, cursed to become a child. Their first meeting: She was thrown off a cliff and landed on him, turning him into a little boy. From then on, she took charge of raising the child and punishing scumbags, while he shamelessly lived off her. She enters the academy, joins the Divine Spirit Corps, and bonds with divine beasts! She's a genius in every element, a master of spirit talismans, and the youngest top alchemist. It's her, her, and always her. One day, the continent's geniuses all cry out in protest: “Is there anything you can't do? Could you at least leave us a chance?” Yan Shi rolls her eyes and answers with perfect seriousness, “I can't fall in love. Does that count?” The Demon Lord pins her against the headboard. “Then I'll teach you properly.” The Demon Lord, a shameless lapdog, versus Yan Shi, a genius in every element who dreams of doing nothing all day.
