Chu Zhou and the others had imagined what this ancient human ruin was like before seeing it.
The word 'ancient' usually made people imagine something relatively ancient and primitive.
In their imagination, this ruin might be related to the horde, hunting, totems, and other elementals.
However, it was definitely unimaginable that this was actually an incomparably huge steel city.
People were always used to linking 'steel' to modern technologically advanced society.
It was difficult to imagine that such a steel city had existed billions of years ago.
In the steel city in front of him stood countless huge buildings made of steel.
Even the ground was covered in huge steel rails.
However, after countless years of corrosion, this huge steel city was already rusty.
Many rusty steel buildings could no longer support their structures and collapsed.
The rusty steel components covered the vision of Chu Zhou and the others.
