On Chen Xin's way to Europe, he once looked down from the sky on the frigate at the Eastern European defense line under construction.

He was deeply impressed by the construction site that spread from one end of the line of sight to the other end of the line of sight, like a giant dragon across the earth.

However, although the defense line under construction is large in scale, it is still inferior to the European defense line that has been put into use and is fighting fiercely almost all the time.

At this time, Chen Xin's land frigate has reached the forefront of the European defense line, and below them is the most intense forward position.

Here, even in the air, there is a certain danger.

Because the air units of alien creatures will launch air raids from time to time to try to break through the defense of the defense line from the air. If they encounter these flying units in the air, it will undoubtedly pose a certain threat to the frigate.

Although for the land frigate, relying on the anti-aircraft weapons on board will not be afraid of those flying units, no one can guarantee whether there will be accidents.

During Chen Xin's flight to the forward position, they have encountered at least three groups of flight units, which makes Chen Xin even think that mankind has lost the air control over the defense line.

Of course, not really.

In the face of alien creatures penetrating the defense, the air defense weapons arranged on the defense line will play their due role and beat down these flying units.

Looking at the track of the tracer bullet on the ground from time to time, which is like a whip flashing electric light, pulling from the ground to the sky, Chen Xin has a very intuitive understanding of the battlefield.

Although it is said that air defense weapons are the first weapon that Chen Xin sees to be powerful in the forward position, in fact, the soldiers in the trenches in the front of the position and the weapons they are equipped with are the most direct collision and confrontation with alien creatures in the forward position.

Because alien creatures are attacking like a tide all the time, the front end of the front position is a line of defense that is also fighting fiercely all the time.

Looking down from the sky, you can intuitively see that the whole defense line is bright.

It was not a light, but the light of the fire from the muzzle of the shooting gun in the forward position.

Originally, the flame at the muzzle was just the moment when the bullet was fired. It could not illuminate much range or last long.

However, with the almost non-stop shooting at the muzzle, these weak flames gathered together and lit up the whole line of defense.

Looking at the fire like a flaming dragon, Chen Xin really felt the fierce battle.

Although I have seen the fighting situation between the army of Yanguo and alien creatures in the front line of the Dongting Lake theater in China, I have to admit that there is still a difference in the intensity between the two.

Perhaps it is because the scale of alien creatures on this side of the European battlefield is larger, so their attacks are more intense!

Because there is no sunshine, the earth is black, but on the other side of the line of defense illuminated by the fireworks, the dark earth seems to be alive. Under the weak light, it constantly rushes towards the line of defense like waves, just as the sea always beats the coast, and this offensive seems to never stop.

Chen Xin clearly knows that within the scope of his eyesight, on the other side of the defense line, all the ground is covered by alien creatures. They are literally attacking like a tide.

This is not an exaggerated description, but a very realistic description, because there are indeed as many aliens as the number of oceans.

"If I throw a nuclear bomb, I don't know what effect it will have?" Chen Xin said to himself, but he was wondering whether it would be worthwhile to do so.

Although limited by the light problem, Chen Xin can't really see the specific situation of the "vast ocean of insects", he can guess how much. I'm afraid even if a nuclear bomb hits, it will only empty a number of alien creatures in a short time, forming a hole, and then it will be filled by other alien creatures in an instant.

Of course, there is no doubt about the power of nuclear bombs, but there are indeed too many alien creatures.

In addition to the trenches at the forefront of the defense line and the anti-aircraft artillery filled behind the trenches, humans also arranged additional artillery positions as fire support.

It may not be true on the ground, but you can clearly see the rear of the defense line in the sky. The light generated by a firing bullet across the sky hit the alien creatures in front of the front position. As Chen Xin expected, it hit craters one by one, created a blank in a short time, and then disappeared in a moment.

Relying on the cooperation of three different configurations on the defense line, mankind firmly blocked the alien creatures out of Europe by relying on such a seemingly thin defense line, and did not let the alien creatures continue to deepen and spread.

In fact, Chen Xin's contribution is very significant.

Although the current defense line seems to be very stable, and a large amount of ammunition pouring down is enough to defuse the attack of alien creatures, these defense lines were already crumbling before Chen Xin arrived in Europe. From time to time, air support needs to be called to eliminate the enemy who has exceeded the bearing capacity of the forward position by several times.

After the soldiers in the forward position gradually began to replace the equipment provided by Chen Xin, their combat effectiveness was effectively improved. When facing the attack of alien creatures, they finally began to pull back the city, which created a situation that the current defense line was stable and alien creatures were more or less killed.

At present, Chen Xin is also thinking about the equipment he provides to European countries.

Before seeing it with his own eyes, it seems that the earth is attacking you. Chen Xin's impression of the European battlefield is basically similar to that of the domestic Dongting Lake theater. Therefore, Chen Xin adopts a specially designed reduced version of the equipment provided to European countries.

However, now, looking at the scene of fierce fighting in front of him, Chen Xin couldn't help asking himself whether he should provide them with more powerful weapons?

Although the reduction of export allocation is a thing that countries will follow in arms export, the current scene makes Chen Xin feel that he should provide the original and improve every trace of valuable combat power against alien creatures.

After all, the sight of "sea of insects" always makes people unconsciously feel afraid and want to seek a sense of security.

For the terrorist upright apes, powerful weapons are the best source of security at present. The greater the power, the stronger the sense of security.

But soon Chen Xin did not think about it again, but asked the captain to prepare for landing.
