Song Yan, a senior high school student, lost his parents when he was a child. Before obtaining a mysterious and amazing ring, he has been often plunged into a vulnerable position and easily marginalized. However, his life is changed because of the cryptic ring.

One day, Chen Shu wakes up and finds himself transmigrated into a parallel world dominated by beast taming, all while being bound to a divine-level Choice System!

As long as he makes choices, he can receive various rewards! With the system's help, his pets gradually evolve into outrageous beings: a slime that can crush a giant dragon with its butt, a husky using elemental skills to make a phoenix cry, a pet that masters spatial power...

One absurd and outrageous beast after another appears, shattering the worldview of the entire world...

On the highest throne of the Beast Taming world, Chen Shu looks back and smiles, saying: "Me? I never follow the rules when it comes to beast taming!"
