Collecting Rent in the Wasteland

Chen Liang, one of the members of the Qidian Orphanage, lived a life of rent collection after inheriting the hotel left by his parents until the wasteland came. What's the use of having a hotel in the wasteland! Oh, with a system, that's fine. I, Chen Liang, want to become the strongest rent collector in the wasteland, but now I have to kill a dozen tenants who have turned into zombies. "Barbed Wire Fence" - "Fence" - "High Voltage Power Grid" - "Automatic Sentry Gun Wall" "Red Brick Wall" - "High Strength Red Brick Wall" - "Grind Stone Wall" - "Steel Wall" "Immovable Hotel" - "Immovable Strong Hotel" - "Mobile Strong Hotel" - "Mobile Fortress" - "Mobile Super Strong Fortress" - "Mobile Automated War Fortress" Looking at the girl outside the door, Chen Liang knew that his first business was coming, wow.
