Although the new slow fire electromagnetic rifle was quickly distributed to the army and quickly reduced ammunition consumption, it is obvious that Chen Xin will not be satisfied with it.

The bullets that can be saved by reducing the firing speed of electromagnetic rifles are mainly those that are fired more when holding the trigger. For example, some elite veterans or soldiers with enough experience will adjust the firing speed to three bursts to save ammunition.

Therefore, although relying on the huge base, the ammunition consumption of the new electromagnetic rifle is quickly reduced after loading, on the whole, the proportion of the reduced part in the whole logistics consumption is not much.

Compared with the whole defense line shooting tens of thousands of tons of ammunition every minute, saving one or two rounds of ammunition each time is really not so remarkable.

So Chen Xin soon turned his attention to other aspects.

In addition to electromagnetic rifles, Chen Xin is most concerned about the anti-aircraft guns widely used in the front line, or anti-aircraft and flat dual-purpose guns.

This small caliber rapid fire gun was originally used for air defense, but after it was leveled in World War II, it was used to fight infantry and destroy vehicles such as tanks, and achieved good results. Therefore, this weapon was also designed to attack the ground.

When this weapon is in the air, it mainly relies on the formation of a barrage at high firing speed to block the aircraft, because it needs to form a barrage, and the natural firing speed must be very fast.

Especially with the progress of modern military science and technology, when the jet aircraft flies higher and higher, the anti-aircraft gun is basically unable to hit, so it is more used to shoot UAVs and ground attack missiles.

Therefore, the requirement of shooting speed is higher and higher.

In the past, this was naturally a very correct idea, but now it is a waste.

After all, you can destroy the enemy with three or five shells. As a result, because the firing speed is too fast, you can shoot out more than ten or twenty shells at once, which is a complete excess of vitality.

Although there is no gap when alien creatures attack, even if they keep shooting in one direction with their eyes closed, they can constantly destroy the enemy, but too high fire speed will still hit the same target many times, resulting in excess firepower.

Before the assistance of Yanguo, these dual-purpose guns were the main weapons that could effectively kill alien organisms on the battlefield. Therefore, a large number of such weapons were deployed on the whole defense line, and the small caliber shells they used were also the largest part of ammunition consumption.

If this part of consumption can be reduced, Chen Xin believes that it is very meaningful to reduce logistics pressure and resource consumption.

Just when Chen Xin tried this, there was news in China, and the high-level ordered him to finish his work in Europe and return to China as soon as possible.

"What happened? Why did China suddenly want me to return home?" Chen Xin frowned when he came to inform his political cadres.

"Academician Chen, you have been in Europe for almost a year, and the domestic side has always had the idea of allowing you to return home." facing Chen Xin's inquiry, the political work cadres hurriedly explained to him: "this time the country hopes you will return home as soon as possible, because the military has turned into the stage of comprehensive counter offensive, and the country needs you, so it will let you return home as soon as possible."

Of course, the reasons given by political cadres are very reasonable. After all, Chen Xin still has a lot of work in China. Staying in Europe for a long time has delayed many of his work in China.

If the war situation in Europe had not stabilized, I'm afraid China would have wanted to transfer Chen Xin back.

At present, the situation in Europe has gradually improved and everything has stabilized. Although it is far from the situation in which the domestic counterattack can be carried out, at the beginning, what the domestic want is to enable the European side to maintain the defense line and not completely collapse.

Even when Chen xinlai came, both China and Lucia were building defense lines in Eastern Europe to prevent Europe from continuing to resist the attack of alien creatures after the total collapse of Europe.

When Chen Xin came to Europe at that time, the minimum goal given to him at home was to support the European defense line until the construction of the Eastern European defense line was completed.

Now, Chen Xin has overfulfilled the task, not only making the European defense line stick to the completion of the construction of the Eastern European defense line, but also stabilizing the whole European order, improving the situation in all aspects, and turning the defense line from precarious to safe.

In the absence of accidents, there is no doubt that there will be a total collapse.

Even the Black Sea area, which Chen Xin had been worried about before, has now established a solid defense line, blocking the possibility of alien breakthrough from here.

Even for the European aid fleet, a large number of materials are transported back to China every week, raising the number of cargo land ships on this route from three to seven, almost one shift a day.

Therefore, it is not very strange for the domestic side to recall Chen Xin at this time.

But Chen Xin still heard some problems from the words of political cadres, so he asked them, "is there something wrong with the domestic counter offensive?"

This is what Chen Xin has been worried about.

Since he learned that the domestic counter offensive had been launched, Chen Xin has always paid attention to this matter. Although he has not received relevant information about major problems, there are small problems such as poor offensive and unnecessary losses caused by insufficient preparation in the process of counter offensive.

Chen Xin is not very worried about these small problems. Since the country is ready to counterattack, it has naturally made plans for these problems.

Moreover, in terms of the current strength of Yanguo, these small problems are within the scope that the country can bear.

Exposing the problems will help solve the problems, adjust them in time and avoid bigger problems.

But that doesn't mean there are no other hidden dangers.

You know, the biggest problem with alien creatures is that they are deep underground. What is revealed on the ground is only cannon fodder that is not important to them.

It is really not difficult for human beings to clear up the alien creatures on the ground, but in order to completely eliminate the threat posed by these alien creatures and completely eradicate them, we must go deep into the underground.

This part is what Chen Xin is most worried about, because mankind has not really designed weapons for use in underground caves so far.

And there is no experience of large-scale operations in this environment.

Whether we can achieve the desired results is a very unknown thing.

It is precisely out of concern about this that Chen Xin handed over the work at hand after thinking for a while, and then left for home.
