Beast Taming: The Pet Monster System Is Pretty Great

[Pets + Elves + Lighthearted + Funny + System] Gongsun Qing studied through the night until he died of exhaustion, then transmigrated to a world full of summoners. From then on, he inherited the life of a tragic hero. The only hope he had left was the Pet Elf System, which helped him trade lives.

Everyone in this world can summon only one battle beast, but Gongsun Qing is an existence that defies the heavens and breaks the world's rules.

From the start, he summons Meowth from Rock Kingdom, which Mega Evolves into Martial Arts Cool Cat, the ultimate support and crowd-control specialist; the Pokemon Rayquaza, the strongest main damage dealer; and countless other little elves, sweeping aside the prodigies of another world.
