You are the security of this old Chinese barracks apartment.

Your duty begins on the first floor. Patrol each level carefully, one by one, until you reach the ninth.

Remember: Always move forward, and walk to the end of the hallway. Keep your eyes open.

Use your flashlight to check every corner, even the slightest anomalies could be a warning.

If you notice anything unusual, turn back immediately! Ignore it, and the loop will begin again. You’ll find yourself back where you started， and you may never escape this building.

The only things you can rely on are your eyes, your memory,

Stay alert, and begin your patrol.
