Chapter 1261 Another memory

Mars colony.

Near the 071 mine site.

A few tire marks were left behind near the abandoned mine for a long time.

Two infantry vehicles and a heavier engineering vehicle were parked next to the sand dune about one hundred meters away from the mine.

The overturned rover was tilted not far away, and the traces of being bitten by devil bugs could be seen on the chassis armor.

Looking out the window, Zhang Hai reached out and pressed his hand on his helmet and contacted the coordinator on the Expedition.

... Has reached the target area and requested air strike support.

This is the Expedition, and the air strike request has been approved. Please place the air strike beacon within thirty seconds.

receive.

Soon, the roof of a siege tank was opened, and a soldier poked out half of his body, took out a signal gun from his waist, and pulled the trigger towards the sand dune on the other side.

The red beacon plunged into the dunes and transmitted coordinates to the missiles falling from the synchronous orbit.

Soon, a dark spot gradually emerged from the sky, dragging a long tail flame.

Before the smearing point became clear, the soldier crawled back into the infantry vehicle and closed the top cover with force.

boom!

The tremor that hit the ground came along the bottom of the car.

The howling gravel blew out dozens of meters away, pasting the entire convoy with a thick layer of sand.

Soon, another dull sound came from the underground, unknown depths.

The exploded flames swallowed all the tunnels, completely suppressing this area.

The convoy continued to move forward, pushing about ten meters.

The construction vehicle was the first to stop, and the staff inside operated the robotic arm, took out a pyramid more than four meters long from behind and threw it on the sand.

Two infantry vehicles protected it in the middle one, one behind, and the electromagnetic cannon on the top was carefully guarded against possible threats.

Their attendance mission today is simple.

There are four pyramids in total, put them all into the ground and then you can return.

Are you sure this thing is really useful?Sitting in the infantry chariot, Zhang Hai looked through the sight glass and looked at the mechanical arm of the engineering vehicle outside, and put the pyramid into the ground bit by bit, and couldn't help but ask.

It is useful in theory.

Sitting opposite the Marine Captain, Wang Qiang looked at the tablet in his hand and responded casually while browsing the instruction manual data on the screen, they were like bats at night, and all we had to do was to get a few high decibels speakers, bury it into the ground, and emit "noise" to the ten kilometers of strata below for 24 hours.If I were those bugs, I would definitely not be willing to stay here.

The Star Ring City Research Institute explained the latest task of these frontline researchers to find out this frequency through repeated trials.

This pyramid was originally used to map the geological information of the mantle circle. After several researchers' magic modifications, it has now completely become such a seismic wave emitter used to create noise of different frequencies.

The fusion battery built into the pyramid can make it work until next year. After throwing a life signal detector into the 071 mine, you can know what kind of frequency the devil worms here respond the most to noise, so that they turn around and run away after hearing it...

In addition, in order to prevent the bugs from biting it, the construction vehicle will have to build a few pieces of steel near this one in a while.

It's that simple?The Marine soldier sitting next to Zhang Hai asked with some uncertainty.

He was a new boy named Koenig, an immigrant from Italy, with a rank corporal, serving as the assault soldier in the squad, replacing the injured Sergeant Miller.

On the Expedition, they simulated the battle with the Devil Worm through the training program in the Phantom Helmet.

And in simulation training, they are taught that any behavior that touches the ground is fatal.

It's that simple.Wang Qiang responded lightly, his fingers tilted on the tablet, and then looked at Zhang Hai. Can you please get closer there?There may be another solar wind outside, and the signal here is very poor.

no problem.

He reached out and pressed his hand on his helmet. Zhang Hai and the soldier in charge gave instructions, and soon the infantry vehicle drove to the next to the construction vehicle.

The four-meter-long pyramid has been completely submerged into the desert, leaving only a platform less than a foot high on the surface.

In order to prevent this thing from being buried under the sand, the construction vehicle also inserted a new national flag on the top of the platform as a mark.

What's done?

After looking at the engineering car that was put away the robotic arms outside, Zhang Hai looked at Wang Qiang and asked.

One is not enough, it takes about four.Wang Qiang set the parameters on the tablet, then pressed the start button, surrounded the 071 mine point into a square, and then emitted shock waves at the same time. We will have the mobile phone data here.

Is this thing really useful?are you sure?I feel like there is no change at all.Koenig doubted.

Because it emits ultrasound, and you stand on the back of the shock wave excitation surface, the impact on you is at most that your heart rate has slightly faster than half a beat.Wang Qiang grinned at the corner of his mouth and put away the tablet. If you stand directly under it, you will feel what life is worse than death.

……

The first floor of the Future People's Building is under the cusp.

After walking down from the elevator, Jiang Chen followed Dr. Amos and walked side by side in the corridor heading to the laboratory.

After you fell into a coma that day, I lost the connection to the drone.At first I thought the drone was broken, but then I thought about it carefully and the more I thought about it, the more I felt something was wrong.If the memory of the Gaia civilization is used as a springboard to communicate with you who are directly bridged on the drone, there is no reason to destroy the drone.

so?Jiang Chen asked.

So, I guess, is it that Gaia civilization that made some minor modifications to the communication frequency of our drone communication chips through some special means?After all, we are just toddlers in the research of Crane particles, but they are quite mature. If you want to plug USB into a computer 94 years ago, you must make a conversion interface or simply upgrade the hardware.

Take out the ID card from my pocket, Dr. Amos swiped the door and made a gesture of asking for help. Sure enough, it took more than a month to find this frequency... To be honest, I almost gave up.

Walking to the computer, Amos reached out and clicked on the trackpad a few times, opened the holographic screen, and displayed a PPT in front of Jiang Chen.

This is?Jiang Chen asked with a frown slightly.

Another memory, but what I found was a little different from the one you encountered.Amos shrugged, it was short, if you were to see a world history, it was just a diary, or a memoir or something.After watching it, I leaned on my impression and made it into a slide.

A diary?Jiang Chen looked at the image on the holographic screen and asked, Whose diary?

The last Gaia.After a pause, Amos continued, the one who died in the ruins.
