Rebirth of the Beast Emperor, Invincible at the Start

The Emperor of Ten Thousand Beasts, who was so powerful in the world in his previous life, was reincarnated into a useless prince who can be bullied by everyone! Just when the execution was about to take place, ninety thousand divine beasts were crying and queuing up to make a contract! ! "Your Majesty, we were wrong! You are not useless at all, you are the ancestor of all beasts!" Since I started with a full-level divine pet, in this life, I will be the most tyrannical beast king in the world!
