It turned out that not all the air-raid shelters were flooded. Because this place was connected to the hospital, no one had found this place before.
Thinking about this, Zhao Yu felt that his deduction was correct. In this air-raid shelter, there should be an exit that was connected to the square!
Thus, he quickened his pace and climbed up the stairs to the top floor. In the end, when the stairs extended to the end, he was blocked by a wall.
Zhao Yu shone his flashlight at the door and saw that there was another old metal door on the wall!
Through the small metal door, he could hear the sound of a car driving past, which meant that there was a road outside.
Yes, this is the place!
Zhao Yu quickly pulled the door, but found that it was locked and could not be opened.
However, how could a small lock stop Zhao Yu? He used the universal lock opener, and the hidden lock opened with a sound. The old iron door made a heavy squeak.
