The Great Spirit Pet Adventure

A man spent his childhood studying all kinds of knowledge, hoping that one day, after he transmigrated, he could win poetry duels, face-slap his foes, find secret manuals, take pills, and build a harem. One day, he really did transmigrate, only to discover that everything he had learned was pretty much useless. He'd transmigrated to some strange place! Here, they don't duel with poetry, they compete with pets.
