The Northern Ring Tower was in front of them. The glorious building, which once stood for the highest scientific achievements and civilization of humankind was now disintegrating. The cement wall was cracking from weathering on the outside; most of its bright paint had also faded into dirty, yellowish-brown colors, peeling and falling off the walls. They formed a layer of disgusting soft soil at the foot of the tower. Despite that, the main structure of the tower was still sturdy. The reinforced steel skeleton inside had held the tower up very well. Hence, there was no concern of collapse for now.
