Siheyuan: I'm Invincible with the Sign-In System

College student He Yuzhu accidentally finds himself in the world of The House of Beasts.

He also gains a sign-in System and an independent personal space.

The steel mill cafeteria, the workshop, Old Deaf Granny's room...

Every time he unlocks a new location, he gains a new ability.

God-tier cooking, max-level fitter skills, antique appraisal...

Knowing what fate has in store for him, He Yuzhu decides to change everything.

He won't be a gullible fool for others to deceive anymore.

First Uncle: "Why doesn't Silly Zhu listen to me anymore? Did he find something out?"

Qin Huairu: "Why is Silly Zhu suddenly like a different person? Is he really going to stop helping us?"

Xu Damao: "What's with this guy? How come he's getting smarter and smarter?"
