In the past, the enemies that soldiers had to face were often humans themselves or various natural disasters, and the battlefields they were on were all limited to the earth and would not travel outside the earth.

And this time, the enemy they have to face will no longer be human. So far, the appearance of the opponent is unknown, the level of technology of the opponent is unknown, and the size of the opponent's spaceship is even more unknown. At the same time, the location this time is unknown.

The battlefield is the asteroid belt. Even in normal times, the entire asteroid belt is full of dangers. Not to mention other things, just saying that in the process of building a defense system on the asteroid, there are nearly a thousand people.

Soldiers died in this vast asteroid belt.

At the same time, the nature of this war is also different. No matter what kind of war it was in the past, it was always a contradiction within the entire human race. Even if the war is lost, human beings will still exist.

But this time is different. Once the war with this alien civilization is lost this time, then the efforts made by the entire human race in the past few years will be in vain, and the entire human civilization may disappear in the entire universe. Therefore, it is conceivable that at this time,

How much pressure are these soldiers in the asteroid belt?

But no matter what, since the opposing civilization has arrived in the solar system, they can only do their best to fight.

Then, all the military bases in the entire asteroid belt took action, and countless spacecraft of various types began to fly from these bases, flying towards the defensive positions within the asteroid.

Countless cosmic minelayers fly out of the asteroid belt and fly between the orbits of Jupiter and Mars. They will lay out multiple space minefields there. After all, since human civilization entered the age of firearms, every war has

It has been proved that both landmines and sea mines are quite effective weapons, and they are also very cheap in terms of cost, so space mines will never let them down in space.

What's more, the space mines they deployed are not ordinary space mines. The space mines contained in these space mines are not ordinary explosives. Most of these space mines contain what is currently within the control of human civilization.

The most powerful weapons are nuclear weapons. Of course, there are many types of nuclear weapons, including ordinary nuclear bombs and hydrogen-oxygen bombs. What this space bomb contains is the most powerful nuclear hydrogen bomb among nuclear weapons.

At the same time, among these space mines, as long as they are equipped with hydrogen nuclear weapons, the detonation power is at least equivalent to the power produced by 10 million tons of TNT explosives. Of course, in addition to hydrogen bombs, there are also ordinary space mines among these space mines.

Nuclear weapons, that is, nuclear bombs.

Just when these military bases in the asteroid belt of the solar system were all taking action collectively, at this time, the human base on Mars also became busy.

Nowadays, the Mars base built by humans on Mars is no longer comparable to that of more than a year ago. More than a year ago, there was only one base built by humans on Mars, and it was only beginning to take shape, and could only sustain a few tens of thousands of people.

However, on Mars today, over the past year or so, human civilization has successively built dozens of bases on Mars, and the scale of these bases is quite large. The largest of them is Mars.

The North Pole base, after all, this base is the earliest base established by human civilization on Mars.

Now on Mars, the Arctic base alone can maintain the living needs of more than 2 million people at the same time. At the same time, a large number of weapons and ammunition are also placed in this base. As soon as the war starts, these weapons and ammunition can be supplied continuously.

destined for the asteroid belt in the solar system.

Of course, among the bases built by human civilization on Mars today, in addition to the bases on the ground, there are also many bases built in the past year under the surface of Mars. After all, if the war really starts, what if?

If someone slips through the asteroid belt, then Mars will definitely be their primary target, and these military bases on Mars will definitely be targets they will attack.

Therefore, these military bases on the ground of Mars still pose a considerable threat. Compared with these military bases on the ground, these underground military bases are much safer.

"Mr. Zhang, our warning satellite has sent new information. The content of the information is just as we expected. The flight trajectory of this asteroid did not come from the direction of our solar system and our earth.

It was man-made reasons that caused the asteroid's flight trajectory to change and fly towards the earth.

According to the data sent back by the detector, the flight trajectory of this asteroid has changed again, and its flight speed has also accelerated. Previously, the flight speed of this asteroid was about 350 kilometers per second, but now this asteroid

The asteroid's flight speed has accelerated to about 370 kilometers per second.

In other words, during this period alone, the asteroid's flight speed increased by 20 kilometers per second. If there was no human intervention, even if the asteroid's flight speed was slightly accelerated due to the gravity of the sun,

Not that it has accelerated by 20 kilometers per meter in less than a month.

At the same time, according to the images transmitted back by our warning satellite, hundreds of faint lights were faintly found on the back of the asteroid. According to the judgment of our scientists, this should be the engine of the spacecraft during flight.

The light emitted, and the type of this engine should be similar to the plasma engine on our earth and in our human civilization.

In other words, our previous judgment was very correct. Although the technological level of the other party's civilization is much more advanced than ours, it is still within the controllable range. The engine used by the other party's aircraft is also a plasma engine rather than other more advanced engines."

At the Lunar Space Command Center, just as Zhang Yi was standing in front of the virtual screen, patiently looking at the virtual map of the entire solar system's defense facilities on the virtual screen, Qi Gong walked in with a document in his hand and said to him.

"What? Our warning satellite has sent back new data, and found the tail flame emitted by the opponent's spacecraft engine? Good, very good. In this way, we can be more certain about the engine used by their spacecraft.

It is still a plasma engine, which has not changed much from the engine used by the detector we captured before. Although it is possible that the engine they are using now may be more advanced than the engine used on that detector.

Some, but according to my inference, it will definitely not advance any further. This can be seen from the acceleration of the asteroid during this period." After listening to Qi Gong's words, Zhang Yi felt much more relaxed.
