Can you recommend an ancient novel about magical beasts?

I remember that the beginning said that the main character was reborn into a world with magical beasts as the main characters, but the main character was a loser. It seemed that the teacher at school took them to find magical beasts. He signed 4 magical beasts that were about to die (they were Green Dragon, White Tiger, Vermillion Bird, and Black Tortoise. When I opened it, I didn't know which four sacred beasts were the real ones). In fact, in that world, each person could only sign one magical beast. Later, the main character and his magical beast became more and more powerful. I don't remember what the name was. I hope that the big one who knows can tell me the name of this book.
The main character was born in a big family. I'm bored. It's a very good novel. I've read it before, but I can't remember what it's called.

Answer 1

I recommend "The Divine Beast". This modern romance novel tells the story of a legendary bandit group, which involves the use and control of magical beasts. I hope you like this fairy's recommendation. Muah ~😗
