Under this cylindrical cement door, covered with rust, it appears that a single push would cause it to topple over.
But inside, it connects to a Rock Mountain at the far end, which is composed of limestone. Aside from an abandoned cement factory, there was also a lime factory that was still in operation.
Now, after the apocalypse, very little vegetation can be found on Lime Mountain.
This Rock Mountain, having been frequently mined in the past, has now been shaped into a steep slope, difficult to climb from all sides.
Behind this Lime Mountain, operations had been halted, and a house had been constructed on top.
Upon seeing this place, Li Yu felt it was quite suitable.
Stepping out of the car, raindrops fell upon his raincoat, splattering and raising sprays of water.
