A Man From Morgany?

Bam.

The men all fell like flies unconsciously.

In fact, they should even be lucky that they got electrocuted by the fence at the level they were at.

Why?

Because the higher one climbed, the higher the amount of voltage distributed on the fence.

At every certain distance around the fence, one could see several overly thin flat poles incorporated with the fence.

And around every pole on the other side of the fence, there were stationary circular lights fixed on the poles moving up, down, up, down.

So no one would dare climb the fence from the poles.

Their only option would be to climb on the fence.

And these poles had several metal strings, similar to phone lines, that had been wrapped and coiled with the fence itself.

But unlike phone lines that had these wires covered in insulation, these ones were exposed and touched the metal fence, transferring the electricity by conduction.
