Chapter 1262 (1/2)

Mars colonies.

Near 071 mine.

Near the abandoned mine for a long time, a few tire marks have been left for a long time.

Two infantry vehicles and a heavy engineering vehicle were parked at the sand dune about 100 meters away from the mine. The overturned rover is not far away, and the traces of being bitten by the devil bug can be seen on the chassis armor.

Looking out of the window, Zhang Hai put his hand on his helmet and contacted the coordinator on the expedition.

“…… We have reached the target area. We need air support. ”

”This is expeditionary. The air raid request has been approved. Please place the air raid beacon within 30 seconds.”

”Yes.”

Soon, the top cover of a buggy opened, and a soldier leaned out of his body, took out a signal gun from his waist, and pulled the trigger at the sand dune on the other side.

The red beacon plunges into the sand dunes and transmits coordinates to the missile falling from its synchronous orbit.

Soon, a black spot appeared in the sky, dragging a long tail flame.

Before the black spot became clear, the soldier got back into the van and slammed the lid on.

”Boom!”

The tremor of hitting the ground came down the bottom of the car.

The roaring gravel blew out tens of meters away, covering the entire fleet with a thick layer of sand.

Soon, I don't know how deep underground, there is a dull sound.

The explosion of flames swallowed up all the tunnels and completely suppressed the area.

The team continued to move forward, about ten meters.

The construction vehicle stopped first. The workers inside operated the mechanical arm, took out a four meter long pyramid from behind and threw it on the sand. Two infantry vehicles put it in the middle one after the other, and the electromagnetic gun on top of it was carefully guarding against possible threats.

Their mission today is simple.

A total of four pyramids, they are all connected into the ground, and then you can return.

”Are you sure it works?” Sitting on the buggy, Zhang Hai looked at the mechanical arm of the engineering vehicle outside through the sight glass, and bit by bit he inserted the pyramid into the ground. He couldn't help asking.

”It works in theory.”

Sitting opposite the Marine Corps leader, Wang Qiang looked at the tablet in his hand, and while browsing the instructions on the screen, he said casually, ”they are like bats at night. What we have to do is to make a few high decibel stereo systems, bury them in the ground, and continuously emit” noise ”into the stratum 10 kilometers below. If I were that group of worms, I would not want to stay here

The latest task of these front-line researchers is to find out the frequency through repeated experiments.

This pyramid was originally used to map the geological information of the mantle sphere. After several researchers' magic transformation, it has become such a seismic wave transmitter, which is used to generate ”noise” of different frequencies.
