I Fix Air-Conditioner

The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door. The door knob to the room rattled slightly, and the faucet in the bathroom kept dripping even though it had been screwed shut. There was a rubber ball that rolled on its own underneath the bed. Wet footsteps started to surface one after another on the floor. 
At 3 am, Chen Ge held a cleaver in his hand as he hid beside the room heater. The call he was trying to make was finally answered. "Landlord, is this what you meant by 'the house can be a little crowded at night'‽"

Having Xu Yin lead the way, after making sure there was no danger, Chen Ge entered the place. He followed the wooden stairs to get to the bottom of the room. Chen Ge ended the call and used the flashlight function on his phone. He bent down and crawled forward. After three or four meters of walking, there was a steel door with police tape.

Probably due to the moisture underground, the door was covered with red rust. Chen Ge tried to push the door and discovered something surprising. The door seemed to have grown into the surrounding soil and formed a whole entity. No matter how hard he pushed, the door did not budge.

Chen Ge inspected the door. There was no even a keyhole, so the possibility of it being locked was zero.

Looks like I have to use another method.

After taking out the hammer, Chen Ge did a quick calculation between the tunnel and the surface.
