Surviving in the Stairwell: I Have the Ultimate Sign-In System

This is a game that every adult on Earth takes part in.

From the bottom to the top, no one knows just how many floors there are!

Some rooms on each floor hold terrifying monsters and ghosts, while others contain food and supplies.

They have only one goal: keep climbing and search the rooms for supplies.

Make it out alive!

But when Duan Jiang entered the game, he awakened a System right from the start.

"Ding! Congratulations, Host, you have arrived at Floor 1,000! Sign-in reward acquired! Thompson submachine gun acquired! ..."

While countless people fought tooth and nail to survive, wondering whether they'd find food on the next floor,

Duan Jiang burped, full and warm, and started thinking about other things.
