Beast Taming: My Cat Emperor Is Overpowered

This is a world where humans and spirit beasts coexist. Spirit beasts wield immense power, and humans form bonds with them through contracts to become beast tamers. Beast tamers and their spirit beasts fight and live together, and can even fuse and evolve to gain even greater power.

The protagonist, Lin Yi, accidentally transmigrates to a world of beast taming, gains a Beast Taming System, and contracts a spirit beast that looks adorable but is actually a scheming little cat named Blackball. He faces all kinds of challenges and opportunities, continually surpasses himself, and gradually grows into a powerful beast tamer. In the end, Lin Yi is carried to victory by Blackball, defeats the evil forces seeking to rule the beast-taming world, and becomes its king.
