Chapter 46: A Bedsheet Dragnet

Thirty meters above the ground.

Twelve firefighting drones, like ghosts, silently hovered.

The advantage of propellers is that they leave no exhaust trail, and their noise is low.

On this cloudy night.

Apart from night vision goggles, the naked eye can't see a thing.

Even if you can hear the sound.

It's difficult to locate the drones.

Tang Rui moved the mouse and marked a point on the map.

Then he selected the drones and clicked on the stealth infiltration mode.

Woo-woo-woo...

After receiving the command.

The electro-optical systems of the twelve firefighting drones started working.

Ground scanning system.

Laser ranging system.

Optical detection system.

Infrared detection system.

These devices on different drones were activated simultaneously.
