A muffled explosion echoed from the lobby on the first floor of the small building, and the already dilapidated wooden door seemed to have been hit by a battering ram, spraying out plenty of wood chips and thick smoke...
Just as Mountain Eagle was about to rush inside, he heard the crisp sound of hand grenades being primed, and soon saw four Offensive Hand Grenades falling from upstairs, landing in the snow in front of the corridor.
Mountain Eagle almost had no time to think. The moment the hand grenades hit the ground, he turned and shoulder-pushed the broken door open, charging into the lobby.
By now, all illumination devices in the lobby had been blown out, leaving only a few dim emergency lights flickering in the corridors on both sides. Once the door was completely opened, the wind and snow blew fiercely into the small building.
