Lin Fei: A Special Talent for Cat-Type Spirit Beasts?

[Beast Taming + System + Evolution + Leveling Up] This is another world where beast taming is the mainstream. Animals, plants, elements, undead, machines... Nine-Tailed Flame Foxes, Life Ancient Trees, Thundercloud Spirits, Skeleton Lords, mechanical shipgirls, and even antique swords and blades that have given birth to spirits can all become spirit pets. The humans who contract, raise, and command them are collectively known as Beast Tamers! Lin Fei transmigrates to another world. Because of his talent, he can only form contracts with spirit pets represented by felines. With help from the System, whose presence is pretty low-key, he gradually grows into a champion Beast Tamer who represents his country in battle.
