A massive concrete wall, like a heavenly pass, stood dozens of meters high, stretching across the landscape.
It seemed to separate the entire Rhombus Ring City Circle from the wilderness, as magnificent and sturdy as the Great Wall, extending in a circle so far that one couldn't see its ends to the left or right.
An asphalt road about ten meters wide served as the only passage to the outside world.
Upon closer inspection, one could see several abnormally thick, massive metal gates suspended and retracted, seemingly arranged and hidden within the wall above the tunnel's entrance.
"This is the Ring Wall. There are only four passages in total."
A convoy, led by an armored car, drove slowly, coming to a brief stop at the wall's exit.
A dozen or so soldiers from the Mechanical Violence Team in black combat suits, armed with live ammunition, leaped from the vehicles. They patrolled the vicinity, maintaining guard, and recounted the vehicles and supplies.
