Climbing up to the location of the observation room, Chen Xin wanted to thoroughly inspect the upgraded observation room.
From the outside, the upgraded observation room appeared like a flat oval canned box embedded in the mountain, covered with snow, inconspicuous in the dark environment.
Facing the shelter's entrance was the observation port, still that narrow slit just enough to peer out from inside, making the entire observation room resemble a machine gun bunker commonly seen in war movies, lacking only the heavy machine gun that Chen Xin hadn't placed inside.
The vent moved to the "bunker" exterior wall after the upgrade was a louvered design, where air discharged from the shelter flows through the pipes with lower temperature outside the observation room, cooling down significantly before being expelled from the vent on the vertical wall façade.
