In this way, the secrecy procedure finally got off to a difficult start under the vigorous promotion of the Northern Capital, but no one knew how much of a role it would play in the future war.

Many years later, Ye Han was embarrassed when he looked back on this past.

The secrecy program has been improved several times since then, adding many special functions that play an auxiliary role, such as judging the host's environment through optic nerve signals; Another example is to judge whether the sound heard belongs to a human through auditory signals; There is also a tactile nerve signal to determine whether the host is wearing power armor......

All in all, it is a variety of judgment programs written according to this idea, through intelligent comprehensive evaluation, to get the result closest to the answer, and to judge the host's situation through the result.

In this system, comprehensive judging is the most important part.

For example, both the visual and auditory senses can tell that the host is surrounded by aliens, but through the sense of touch, it can be determined that the host is still wearing power armor, and then through various nerve signals, it can be judged that the host is wheezing violently, adrenaline rushing, or other signs of vigorous exercise, and the final result can be concluded that the host is in a fierce battle, and the final result of standing still.

Of course, the actual situation is much more complicated than this, but the principle is the same.

At that time, confidentiality procedures were already a must-have program in all biochips.

At this point, the dispute over the secrecy procedure has come to an end, and although the discussion of the fighters has never stopped, as long as it is not out of line, the base will not interfere indiscriminately.

After all, this thing is related to the lives of the soldiers, who hasn't been a little rebellious? It's not a problem to complain a few words, you can't even leave a channel for this kind of venting, right?

The military has never been a reasonable place, but when it comes to humanization, it's not really that rigid and old-fashioned.

After all, the times are changing, and if you can't keep pace with the times, sooner or later you will be eliminated by the times.

The core of the Qiongzhou base during this period of time is the confidentiality procedure, but everything outside the base still runs according to the original trajectory and has not been affected by any unexpected factors.

The aliens who landed on Earth have never stopped, and in addition to southern Europe and Oceania, they have created local conflicts in many regions, but all conflicts have ended in the defeat of aliens.

This is not how strong the human race is, but that the human race has always held the air supremacy of the earth, and it is the absolute air supremacy from the sky to space, no matter how many troops and how determined the aliens invest, they can't stop the ruthless attack from the sky.

The tactics of the human side are very simple, after discovering the swarm or bugmen, they will immediately destroy the communication network in the area where the incident occurred with long-range firepower, and then mobilize troops to intercept them as quickly as possible, forming a local absolute advantage.

Next is the home of the Air Force and long-range firepower, and all kinds of air strikes and long-range strikes emerge in an endless stream, in short, they are piled up with firepower.

This tactic is simple and brutal, but it works surprisingly well.

However, the location chosen by the aliens is often unexpected, and the troops of various countries do not have time to move to the scene of the incident, and even the air force cannot reach the ground in a short time.

At this time, it is the highlight of the space fleet, the firepower coverage from space is more cruel and ruthless than the air force, if the moon happens to hang in the sky, then congratulations, the aliens have won the jackpot again, the death light from the super cannon will ruthlessly destroy everything on the ground, and only by hiding underground can you escape for your life.

A general sighed: As long as it is based under the moon, mankind can be invincible!

The warriors are more straightforward: only with the moon on their heads, the battlefield belongs to humans.

The people are more down-to-earth: as long as they can see the moon, they don't have to worry about bugs.

In fact, the space fleet's ground strike is also extraordinary, but the audio-visual effect of the space fleet is really not as good as the super cannon, and the result is that the super cannon has unwittingly become a totem-like psychological pillar, which is really beyond everyone's expectations.

Under the joint strangulation of the ground and the sky, southern Europe, which was once in the hands of the enemy, was taken back by humans without much effort, but the war destroyed civilization, and the whole of southern Europe was almost in ruins, plus there were countless giant insects hidden underground, even the most persistent people were unwilling to return home at this time.

As a result, southern Europe, which had returned to human hands, had become a huge military camp, with fortresses, trenches and barbed wire fencing the vast southern Europe layer by layer, and every open space was covered with mines, turning the whole of southern Europe into a huge minefield, leaving not even a safe road in the army area, and relying on helicopters for external transportation.

In order to prevent the insect swarm from developing from underground to Central Europe, the European side has also planted a batch of large-yield nuclear bombs on the ground to listen to the underground situation 24 hours a day, and once it hears the sound of the insect people digging holes, it will immediately detonate the nuclear bombs, create an artificial earthquake, and prevent the insect swarm from continuing to dig.

Domestic netizens can't help but praise that the cage policy of Europeans is much more thorough than that of a small book!

However, no matter how thorough the European side is, it can only contain the insects on the ground, and there is nothing they can do about the underground insect swarm.

This is not only a problem in Europe, but also a common phenomenon in all parts of the world, where swarms and insects drill into the ground without saying a word, and the result is that the ground is basically controlled by humans, and the underground is basically occupied by aliens.

This situation is not only unexpected by humans, but also not expected by aliens, and both sides are depressed by this strange balance, but there is no way to break the deadlock.

The stalemate is not that it cannot be broken, and it is indeed possible to break the stalemate in some areas by means of poison gas and flooding, but the problem is that the speed at which the insects block the hole is too fast, as long as the slightest clue is found, the hole will be immediately blocked to prevent the spread of poison gas and flooding.

In Xiao Yuan's words, this is a new stage in the development of the battle of wits and courage between the two sides.

It's incredible to think about it, the human fleet has been able to fly to Jupiter to attack the aliens' lair, but it has not been able to clean up the swarm hiding underground.

It is true that a nuclear bomb can destroy the underground cave network, but it only destroys the underground caves, and the insects will not die immediately even if they are crushed by the collapsed soil, as long as they are dug out in time, even the sequelae of lack of oxygen will be wooden.

Moreover, with the speed of the insects' burrowing, it won't take long for the new insight network to be dug up, and destroying the underground cave really doesn't have much effect, coupled with the shortage of nuclear materials, human beings can only maintain this weird balance situation for the time being.

The aliens also thought of some ways to break the game, such as sending giant insects to mine mines, or digging through the foundation of the fortress directly from the ground.

In the beginning, these methods did have some effect, but the mines were finished, and there were still electrified barbed wire; The fortress was dug through, but there was no one on the first floor...... All kinds of battles of wits and courage were staged repeatedly, and the result was that the means of human defense became more and more perfect, and the two sides finally returned to the original point.
