The bright sunshine spilled over the giant wall, reflecting the unique sheen of metal.
The towering wall, over ten meters high and two meters thick, seemed endless at a glance.
The interior of this endless wall was solid rock, with a dark metallic layer on the surface, covered with thorns of iron spikes below five meters high.
Some of these iron spikes were straight, while others had become curved, evidently having been attacked.
A layer of dark red marks covered some of the iron spikes.
These were the dried remnants of blood.
Around these thorny iron spikes, there were also rows of dark cannon barrels, with a diameter of forty to fifty centimeters.
And such cannon barrels were almost everywhere on the surface of the wall.
This was a defensive fortress, also a war stronghold.
The giant wall was the symbol of the Satellite City!
A steel Great Wall forged over more than ten years and hundreds of thousands of lives.
Although some people called it a cage.
