If It's a Door, Even a Demon God Has to Offer Me a Cigarette

Gatekeeper Grandpa System loaded successfully! Bound target: Zhang Chu

Twenty-year-old Zhang Chu joins the world's top academy for people with supernatural abilities as a security guard, hoping to save himself forty years of struggle.

He was planning to drink tea, read the paper, and coast through the days. But the abilities the System gave him are absurd:

Job duties: As long as you stand at the entrance, you have absolute authority over everything on either side of the "gate"!

Telescoping gate remote: Press once, and an S-rank genius goes flying two kilometers, car and all!

The guard's stare: Glare once, and even an Abyssal Dragon must show its health code. A red code means instant execution!

Public fire extinguisher: Give it a spray, and a Fallen Angel's holy halo shatters. They'll obediently go clean the toilets!

When an SSS-rank Abyssal Rift explodes open at the school gate, the students and staff despair.

Zhang Chu strolls out with his thermos, points at the gods and demons filling the sky, and shouts:

"You, the one with wings! Who said you could fly in without registering? Get down here and mop the floor tiles!"

The demons and gods: "???"
