Leo's life takes an extraordinary turn when he transmigrates into a pet-centered world where people unlock their Taming Space at the age of 16, becoming Tamers. In this world, Leo runs a run-down, barely-standing family-inherited pet store. After transmigrating, Leo found that his Taming Space was linked to a cultivation world. Initially, he wondered about the usefulness of having access to another world, but then the realization dawned on him. In the real world, acquiring pet resources would be hard for him. In the cultivation world, pet materials were abundant, and while they weren't that easy to acquire, it was more accessible to him.  In a world where pets were regarded as demonic beasts to be hunted due to their destructive nature and overwhelming numbers, controlling them was unpopular and rarely practiced compared to other cultivation paths. This made anything related to this path fairly cheap.  The situation was different back in the pet world, where every pet-related material was valuable. This world became a goldmine for Leo, offering him a path to becoming stronger in both worlds and achieving wealth.
