Light Rider (Part 1)

A few seconds later, the Command Center proactively contacted Yuan Mu and confirmed that there was a problem in the operation teams' area as well. The observer, Little Sister, said, "According to the building blueprints, the nearby walls are constructed from special materials such as electromagnetic-shielding concrete, restricting electromagnetic wave activity in the relevant area. If you go any deeper, communications may be obstructed. EMP-type electromagnetic weapons will also be limited."

Yuan Mu exchanged a look with Light Spot. In the increasingly dim light, they could barely make out each other's cold, hard metal faceplates.

In such an environment, Yuan Mu instinctively pressed a hand to his communications module, trying to make the conversation smoother through physical force. "Listen, I used to work with conductive concrete. This stuff is indeed useful, but it isn't a completely absorptive material. It should reflect and refract, understand?"

"Uh..."

"The problem now is that we can barely 'see' anything, even with our night-vision equipment activated. Combined with your conclusion, that means the visible light, infrared rays, and perhaps an even broader range of electromagnetic waves in our area are all missing. Otherwise, this wouldn't be happening!"

Under normal circumstances, the environment humans lived in should have been a boiling soup of radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays of varying frequencies, wavelengths, and energy levels, interwoven and churned together. Some were more abundant, some less so, and upon encountering matter, they underwent penetration, refraction, absorption, and all manner of other effects.

Humans were bombarded by electromagnetic waves every moment of every day. They had adapted to this environment and even actively made use of it as an important way of perceiving the world. But the situation facing the two Deep Blue Squads, "Forest" and "Ying Huo," was this:
