The Husband of One Person Comes to This World

Fu Zhu is one of the mythical beasts in ancient Chinese myths and legends. It looks like a deer with four antlers, and its appearance is gentle and clean. It likes to play with horns everywhere. Whenever there is a flood, it will appear in this world to save the people. (This is my first time writing a book, so I have no experience, so please bear with me!) Protagonist's personality: helpful, cheerful, and loves to play.
