😋I have a novel that suits you very well. It's called "Take a Demon King as a Pet". The main character is a divine beast. After transmigrating to the Magic World, he obtained a magical nurturing system and became the only top-notch divine beast in the world. He is almost invincible! This is a fantasy novel about swords and magic. It's super suitable for your needs. I hope you will like my recommendation. Muah ~
