[Invincible protagonist] [Multiple heroines] [Beast-taming with all kinds of creatures]
Other people's spirit summons: Mountain Spirit! Jade Sea Cloud Wyrm! Destroying heaven and earth!
Gu Ming's spirit summon: ...A little black cat? The kind that's so hungry it keeps meowing?!
The whole school mocks him, his parents fret, and his best friend Lu Liwei pats his epic-grade stone spirit. “Don't be scared! I'll help you soar!”
Gu Ming looks at the golden finger panel for the “little useless thing” before him: [True Name: Taotie] [No upper limit, can evolve multiple times]...and falls silent.
Seven days later, at the Dome Secret Realm.
As Lu Liwei's stone spirit rampages ahead, Gu Ming quietly takes out some dried fish. “Ancestor, dinner's ready. Target: eat the entire secret realm!”
Later, watching his “cat” swallow the BOSS in one bite, then burp and swell up into a ball...
Lu Liwei: “??? Weren't you supposed to help me soar?!”
Everyone: “Holy crap?! That cheat's cat is the real world-devouring beast?!”
[Blurb summary] A cat from the start, and it turns out I'm the cheat? An epic brother helps me soar? No, it's an insanely hungry ancestor who carries you to an easy win!
