As early as last month, the colonial Frontline Institute and the Star Ring City laboratory finally found the right frequency after joint research.
Through the magically modified seismic wave excitation device, twelve shock waves of different frequencies are continuously emitted underground, and a black domain can be created within a range of more than ten kilometers underground.
In this black field, the devil worms cannot correctly determine the direction, nor can they determine the surrounding and surface conditions, and at the same time they will cause strong physiological discomfort.
Experts from various countries in the laboratory call it ultrasonic fences.
Twelve seismic wave excitation devices were deployed around the colony, surrounding the entire colony with ultrasonic waves into a dodeca-shaped isolation wall.
Now, with the colony as the center and within a radius of more than ten kilometers, it has become a forbidden area for the devil insects.
Thanks to this, the colony development work that had been stagnant for a long time can finally be reopened.
Under the command of Captain Hong Zewei, the colonial engineering team repaired the perishable hydroponic plantations and pastures arched by devil worms.
At the same time, according to the plan of the Space Command Center, the first highly automated steel plant was established on Mars.
Mining iron ore on Mars does not require mining wells at all.
Mars is full of iron ore.
This sentence is not false at all.
You can smell the rust when you pick up a piece of sand from the ground.
The raw materials for production are just under your feet. A newly built iron ore factory only needs to shovel truckloads of sand into the boiler to produce batches of finished steel.
Most of the smelted slag is silica, and can be used as glass and concrete building materials after a little treatment.
Part of the steel produced is used for colonial construction, while the other part is made of rebar and stainless steel plates to reinforce the surface of the colonial area.
Yes, the steel on Mars is so cheap that it can be used as floor tiles to pave the road.
The engineering team responsible for the construction will first push the steel bars into the ground, then fill them with cement, pour them into concrete foundations, and then lay a layer of high-strength stainless steel on the concrete floor.
In this way, even if a drill bit is grown on the top of the devil worms, they will not be able to penetrate the floor of the colony.
Although there is an infrasonic fence, most people still feel uncomfortable when they think of the tunnels excavated by devil bugs under their feet.
Even just in case, this alloy floor is absolutely necessary.
In addition, concrete has a strong sound insulation effect and can effectively limit ultrasound to the ground, which is also beneficial to the health of colonists in the colonies.
In addition to iron ore, the geological brigade where Wang Qiang is located recently discovered a carbon mine with considerable reserves in a meteorite crater ten kilometers away from the colony.
This purely natural carbon ore is rare on Earth in an oxidative environment, but seems to be very common on Mars.
Relying on graphite produced by this carbon mine, the colonies can now produce graphene independently without relying on imports from Starring City.
The steel plant and the graphene plant have been built, and now there are only two tasks assigned by the headquarters to the colony. One is to build a ground base station for space elevators on the equatorial line, and the other is the 071 project.
Now, the Star Ring Marines have established an operation base above the 071 mine site.
The construction team of the colony reinforced the road surface with concrete and steel. At the same time, they also established machine gun post towers, communication base stations, accommodation barracks, garages and other facilities.
In addition, the engineering team's drilling vehicle has drilled into a tunnel that can be passed by infighting vehicles around the 071 mine site, and has reinforced the tunnel with reinforced concrete to prevent destruction from devil insects.
Drilling the tunnel into five kilometers or even deeper strata is undoubtedly a test for the construction technology of the colonial engineering team.
However, they have experienced this test many times. After more than a month of hard work, the drilling car finally reached the edge of the five-kilometer lower Gaia civilization ruins.
The next thing they had to do was to continue drilling downwards around the ruins and drill out a spiral passage.After determining the hierarchy of the Gaia civilization database, dig into the remains.
Here is Team A and we have reached the edge of an unknown area.
Following behind the drilling car and looking at the map on the holographic screen in the helmet, Zhang Hai reported to the command center about the current situation.
Move forward.
receive.After finishing the contact with the command center, Zhang Hai switched the communication to the team channel, set up the rifle in his hand, aimed at the channel ahead, and all combat units should pay attention that high-density life signals were detected in front, and we were about to enter the dangerous area.Protect the drill, open the insurance, open the fire freely, and act.
The drilling truck continued to advance, and the engineering truck behind him pushed the rebar into both sides and welded it to death, while pouring a quick-drying concrete reinforcement tunnel.
The Marines followed closely behind, holding the Gauss rifle in their hands and carefully monitoring the front.
If the devil bug may come from a certain direction, it must be right in front of the drill.
When the drill bit drilled into a rock wall, the rock in front collapsed, revealing a large area of space.The drilling car stopped, and the soldiers on both sides immediately stepped forward, but no trace of the devil insect was found in this hollow layer.
Zhang Hai walked to the nearby rock wall, turned on the tactical flashlight and inspected the wall, and found the flesh-red rock blocks and the bacteria clusters growing on the surface of the rock block.
There is no doubt that this is the oxygen supply layer.
He gestured to the soldiers behind him, and Zhang Hai carefully retreated to the reinforced tunnel with the people.Just then, a soldier accidentally discovered a strange follicle.
The dark green follicles look half a human tall, and a thin layer of colorful oil spots can be seen under the shiny membrane under the flashlight.
According to some unknown rhythm, the follicle contracts and expands slightly and stimulates.
I don’t know if it was because the light of the flashlight stimulated it, and its agitation speed increased slightly.
What's this?The rifle in his hand aimed at the insect egg, the soldier reached out and pressed it on his helmet, took a few photos and sent it to the team channel, reporting to the captain, and the situation was found here.
Devil worm eggs?Looking at the images on the holographic screen, Zhang Hai frowned slightly and walked forward with a rifle. It was wrong... Let the drilling car stop.
The drilling car stopped drilling forward.
Soon, Zhang Hai re-connected with the command center.
As soon as the communication was connected, the command center asked.
What happened?Why did the drilling car stop?
Reporting headquarters, this is Team A. We drilled through a hollow strata and found a large number of oxygen-making fungi and a strange insect egg...probably insect eggs.Looking at the agitation follicle, Zhang Hai sent the photos to the Expeditionary Command.
Here is the command center, we have received it, and are sending researchers to the target area to take samples, please wait here.
receive.After hanging up the communication, Zhang Hai gestured to the soldiers behind him and pointed to both sides of the drilling car.
Before the researchers arrive, they will lay out simple lines of defense here.
What do you think this thing will be?Koneg said quietly in the communication channel, aiming at the egg nervously.
Don't know, maybe it's a mutant devil worm?Maybe it is a new species that we have never seen before?To be honest... I have even seen that kind of thing, even if God stands in front of me, I will not feel surprised.
Listening to the sound of teammates chatting in the communication channel, Zhang Hai looked at the insect egg.
I saw that the insect egg was like a living heart, pulsing according to a special rhythm.
For some reason, looking at the insect egg, a strong sense of anxiety arose in his heart...
