The two of them are also dressed differently.

Lin Xiao's body was wearing a long black trench coat, this was still the clothes he used to like to wear, wearing this clothes, Lin Xiao seemed to have become a hunter in the dark night!

And Li Muyun was not wearing the blood-red windbreaker she liked, but changed into the most ordinary dark green combat uniform.

The two of them didn't notice Chu Qiuyue and the others, although Chu Qiuyue and the others had been watching them, Lin Xiao's feelings were indeed very keen, but after all, there were too many people in this headquarters, especially before the two of them came to the main gate, they were obviously going out to fight, and there were not a few people who paid attention to them, Lin Xiao couldn't be all soldiers, right?

Therefore, Lin Xiao didn't notice this side at all.

Chu Qiuyue immediately stood up and said in a deep voice, "Let's go to the lookout!" ”

In the war headquarters, there is a lookout.

This huge war headquarters, in fact, from the inside, you can see the situation outside at a glance, after all, this war headquarters does not have a so-called city wall, but a huge translucent light mask, from the inside, you can still barely see the scene outside.

It's just that it's not so easy to see someone in the distance, after all, it's only translucent, not fully transparent.

However, in order to allow people to watch the battle from inside, the War Headquarters has an observation deck, which is not actually a lookout in the true sense of the word, but two buildings that are not different from other buildings!

Every room in the building is a monitoring room, you can control the scene in which direction you want to see, the large room can be watched by tens of thousands of people at the same time, and the small room can also accommodate about ten people!

The images of this monitoring room are all controlled by the intelligent evolution software of the war headquarters, and the images are taken by hundreds of low-altitude satellites launched by the government, which are extremely clear, as long as you have permission, even the hairs on the faces of the people you want to see can be seen clearly!

The ongoing battle at War Headquarters No. 2 was named the 7152 Guard Battle.

It means that on July 15th, the 2nd War Headquarters Guard Battle!

As soon as he came to the War Headquarters, Lin Xiao used his authority to check the situation of several other War Headquarters.

War Headquarters No. 1 to No. 7 are the outermost of the 50 war headquarters within the official control of human beings on Earth, that is, the front line.

Now, five of these seven war headquarters have launched large-scale siege and defense battles, and the other two war headquarters have also been blocked, seeing that the Anertai people are about to start attacking the city!

There are only three ways for the Antai to breach the war headquarters.

Or use tricks to infiltrate the interior of the war headquarters and destroy the powerful light curtain that envelops the entire war headquarters, without the protection of the war headquarters, the entire war headquarters is like a hedgehog full of weapons, but after all, without defense, it will eventually be drowned by the sea of people of the Antai tribe.

Either that, or directly break through the light curtain of the war headquarters with a saturation attack that exceeds what the light curtain can withstand! But this is almost impossible, because, since the beginning of this war, the Anertai people have tried to do this again and again, but even in the largest battle in the past, the Anertai Fire Group launched 1 billion masters to attack the light curtain at the same time, and the overwhelming, doomsday-like attack finally failed to break this light curtain!

1 billion is nothing for the Anertai people, as long as the Anertai people want to, 10 billion can be mobilized!

However, when the earth human beings officially arranged these 49 war headquarters, they chose the transportation arteries in the mountains, and the headquarters were flanked by towering peaks, and only a range of 50 kilometers in front of them could attack, and 1 billion people used scientific and technological weapons to gather strength to attack, which was already the limit, and no matter how many people there were, they couldn't let it go at all!

Therefore, this second method is almost impossible to achieve.

And the third way is to break through the gate!

This is also the one that is most likely to be implemented.

In order to control the opening and closing of the gate of the war headquarters in real time and not affect the entry and exit of personnel inside the headquarters, the gate is set up to be controlled by manual and computer programs.

Even if the program fails, the manual mechanical opening can open the fixed range of light curtain at the main entrance, and as for the actual opening time, it is almost only a moment!

Therefore, as long as the opponent can break through the first 50-meter-thick steel gate in front of him and break through the guards of the human warriors of the war headquarters, he will be able to find a way to open the gate of the war headquarters through the method of mechanical opening and drive straight in!

Therefore, it is crucial to guard the gates!

The translucent light curtain above the war headquarters has two layers, the inside and outside, and the middle is the combat readiness area, where the guards rotate and replenish, etc.

Lin Xiao used the access control card he got to swipe it on a machine next to the light curtain at the main entrance, and then after connecting to the evolution software and verifying it, the translucent light curtain in front of him disappeared instantly, and was replaced by a hole with a radius of hundreds of meters in front of him!

This huge hole is the inner light curtain gate!

After passing through the light curtain door, the hole closed again, and there was no sign of opening it.

Then, what caught Lin Xiao's eye was a large empty field!

The width of this empty field is about 500 meters, and the length is the circumference of the entire war headquarters!

In the open field, there are many tents, as well as official vehicles transporting supplies, and even a lot of medical vehicles!

Here, it is like the rear headquarters of a battlefield, and all preparations for war are being carried out intensively!

At the front, there is a row of 20 black gates, each of which is hundreds of meters wide and 30 meters high!

If 20 gates are opened at the same time, it will be enough for more than 5,000 people to enter and exit side by side!

When the earth human warriors marched, they were very disciplined, and after arranging into a complete phalanx, they could even enter and exit tens of thousands of people at the same time!

In addition, the distance between the front and back is also very regular, as long as there is no congestion, millions of people can pass through in just one minute!

It's just that at this moment, of the 20 gates, only the middle two gates are open, and there are people guarding them at all times, ready to close the gates at any time!

Looking at this thing that seemed to exist only in myths and legends, Lin Xiao's heart was also full of shock!

After a moment of silence, Lin Xiao took Li Muyun and walked forward slowly.

When he came to the gate, Lin Xiao handed over his access card.

The guard at the door quickly swiped the card, and then his face turned to the side, and he glanced at Lin Xiao strangely, then at Li Muyun, and frowned slightly.

The guard's eyes were full of doubts, and when he handed the card back to Lin Xiao, he couldn't help but ask, "Are you sure you want to take her out?" ”

Lin Xiao smiled and didn't answer, but walked out of the open door with Li Muyun.

It wasn't until Lin Xiao and the others disappeared from view that the guards inexplicably withdrew their gaze.

Another guard on the side asked softly, "What's wrong?" ”

The guard groaned for a moment, then said, "These two guys are free men!" ”

The other guard was stunned for a moment: "Free man? Now that a large-scale battle is going on, what are the free men going out to join in? Think you didn't die fast enough? ”

"I don't know! In addition, the man and the woman just now, the man is a two-star strength, the official rank of captain, and the woman is a first-class soldier! These two people are both recruits who have just enlisted in the army! ”

As soon as they heard this, several guards around them immediately understood the specific strength of Lin Xiao and Li Muyun, and for a while, everyone was stunned!

Lin Xiao's strength is not bad, if he goes out alone, even if he is on the battlefield, maybe he can survive with good luck.

But Li Muyun is different!

With such strength, entering the battlefield as a free man, without many comrades-in-arms around him, is to find death!

And Lin Xiao went out with her, obviously to protect, so these two people had to die!

For a moment, many of the guards looked strange.

But after a moment, one of them sighed and said, "Forget it, don't worry about it! They have all gone out, and each man has a life! ”

The others also nodded, their expressions slightly dimmed.

Because they thought that it was not just Lin Xiao and Li Muyun who were about to die!

And how many of those who went out from here to fight the Antai outside will be able to come back?

Many of the soldiers in the rear or in the headquarters don't know, but those of them who guard the gate know a lot of things!

This battle, even in the history of this war, can leave a strong mark!

From the No. 1 to the No. 7 war headquarters, each war headquarters has launched a large-scale siege war, and the troops invested by the Anertai people in this siege have reached a terrifying 300 million!

Headquarters 2 alone is home to 45 million Antarians in battle!

The other six headquarters are similar!

Headquarters 1 to 7, as the outermost front-line war headquarters, are the largest number of people among all war headquarters, and the security forces stationed in these 7 war headquarters account for half of all human security forces on the entire extraterritorial planet!

That's more than 200 million human security forces!

The No. 2 War Headquarters alone has nearly 30 million soldiers, but some of them are soldiers in charge of logistics and so on.

Therefore, there are about 24 million people who are really able to fight.

And at this moment, outside the war headquarters, the human security forces have invested nearly one-third of their troops!

Eight million human warriors, fighting bloody battles outside, how many of them can come back?

No one knows!

But what everyone knows is that it is impossible to be immortal!

It's war!

An incomparably cruel, incomparably bloody war!
