Lin Mo was reborn in the Pet Continent with his original contract seal and the pet pupil, and opened an inconspicuous "All Souls Pet Store". Others only regarded him as an ordinary pet breeder, but they didn't know that he could see through the hidden evolutionary path of pet beasts and use the contract seal to form a two-way symbiotic bond - helping customers' useless pets change their lives against the odds, customize their own evolutionary path, and accumulate resources and reputation by opening a store. Hope; personally contract with many rare pet beasts, accompany them to enter secret realms, seize soul crystals, and cross-system evolution, and fight side by side against the dark contractors who plunder the origins of pet beasts and the top forces that monopolize high-level pet beasts. Eventually, they will open small shops all over the world, and become the "double master" who can not only cultivate all beasts, but also control beasts and be respected, and reveal the ultimate secret of the contracted symbiosis between pet beasts and humans.
