Chapter 1249 (1/2)
According to the ex factory price of the military industry of the future, the cost of a ground support ground penetrating bomb that can be separated and ignited from the synchronous orbit will cost about S $5 million, including the combat components of the burning and burning bomb, about 5.5 million.
Two hundred rounds of ground penetrating bombs is S $1.1 billion. As for the mass bombs and batteries, they will add up to about 1.2 billion.
If it's a cannon, gold is ten thousand taels.
Less than two weeks after the expedition set out, it reached out to the headquarters for supplies worth more than $1 billion. Even if Jiang Chen's family business is as big as it is now, he has to feel that this thing is too expensive.
In fact, not counting expeditionary's consumption, so far, the total amount of money spent by the ring trade and futurists on Mars is S $20 billion. On the other hand, if we don't count the remains of Gaia civilization whose value is unknown, the value created by Mars colonies is less than half of that.
This is also the most painful place to farm on an alien planet.
You don't even know what the seeds will grow before the crops come out.
Fortunately, not all the bills came from the front line. There were other things as well.
In mid February, based on a comprehensive analysis of stratigraphic information and fluctuations in life signals, researchers at the Martian colony concluded that more than 80 percent of the Martian colony's natural granite like caves, about one kilometer deep, exist in the devil's nest.
If the information is reliable, it may be the shallowest devil's nest ever discovered by the Martian colonies.
Knowing this information, the expeditionary immediately dispatched ground troops to encircle and suppress the devil's nest in this coordinate.
By using a bit truck with a large bit, the expeditionary tunnelled an inclined tunnel into the target formation at an angle of 30 degrees. Before being refitted, this drill truck is usually used to build undersea tunnels on earth, which is more than enough to cope with the relatively loose rock environment of Mars.
At the same time of drilling, the engineering vehicle behind is also closely followed by laying steel support to the tunnel wall, pouring cement and casting concrete wall, so as to prevent the devil bug from damaging the tunnel.
Who says humans can't make holes?
The expeditionary Marines have proved that humans can not only drill holes, but also build roads along them. The concrete wall supported by A-type steel can not collapse the tunnel even if the devil bug gouges a bunch of cement chips on it.
The moment the drill truck rushes in and breaks through the devil's nest.
The chariots in the back rush in and shoot at the devil.
A bloody massacre began.
The horny armor of the devil bug can't effectively protect against a kilogram mass projectile accelerated to N times the speed of sound. But behind them are the eggs, with their backs to their nests, and they can't get into the ground and fight with the invading starring Marines.
The hoarse roar reverberated through the tunnel and was drowned by the sound of the cannons.
Green blood splashed all over the place. In just 10 minutes, at least 50 adult devil worms fell into the pool of blood. In addition to a few devil insects to see the situation is not good, in addition to the whole pot shaped cave, can not see the devil insect can move.
After solving the biggest threat, soldiers in exoskeletons jumped out of the rear cabin door of the infantry vehicle, carried the folded steel wire mesh and quickly rushed towards the direction of the devil's eggs, laying a ”safety belt” between the infantry vehicle and the eggs.
This kind of barbed wire can not be retracted after unfolding, and its strength is very high, especially the longitudinal strength.
After all this, the six infantry soldiers stood in loose formation, set up their rifles, and took defensive positions near the devil's eggs, waiting for the researchers on board to come out and collect specimens.
