At the same time, the weapon designed by Federov adopts the working principle of short recoil of the barrel and the swinging locking mechanism of the double snap shoot, which leads to the overly complex structure of the whole gun, many parts, and extremely inconvenient to disassemble and combine, wipe and maintain.

The shortcomings can be discarded, the advantages can be inherited, and the concept can be learned from each other. Each weapon designed by Yang Tianfeng was not copied from the same weapon, but was the product of drawing on the strengths of others based on the actual production capacity and the needs of the battlefield.

That's why he wanted to change the 38 cover to semi-automatic instead of fully automatic. The bullet can remain unchanged, which can ensure the advantages of long range and high accuracy of the 38 large cover, but it improves the shooting speed and enhances the density of firepower.

In a laboratory with the highest security level in the basement, Yang Tianfeng saw a sample gun that was nearly completed.

The barrel of the 38 big cover, the most common structure of the gas conduction device under the barrel, no gas regulator, the piston is pressed against the bolt frame by the push rod, the piston recoil stroke is less than the stroke of the frame, the gun belongs to the design of the piston short stroke.

"Now it's time for the bolt to deflect the locking mechanism." Li Jianye said with confidence: "Comparatively speaking, this kind of mechanism has good rigidity, simple structure, and is also convenient for production. ”

If the principle of short recoil of the barrel is adopted, there is no need for a piston barrel and a locking lever, and the structure seems to be simpler, but the "hard contact" load-bearing parts are more complex and the mechanical wear will be more serious. Although the short piston stroke is more complicated by the piston barrel and push rod, the shooting accuracy can be basically guaranteed. In terms of ease of manufacture, it is easier to manufacture than a barrel with a short recoil, and represents the right direction for the development of guns.

"And—" Li Jianye hesitated, but still said, "After careful study, we feel that the parts on the design drawings seem to be able to be reduced by two. ”

Yang Tianfeng laughed, patted Li Jianye's arm, and said, "Then according to the method you have studied, it is good to reduce one part." The design I came up with is not flawless, and there is no weapon in the world that is flawless. In the process of manufacturing and experimental use, it is more necessary to continuously find defects and continuously improve them to achieve the best comprehensive performance. ”

This is the advantage of Yang Tianfeng, although his mind is similar to a mainframe computer, he never thinks that what he has come up with is impeccable and cannot be changed.

And if the 38 cover can be successfully transformed, it will not only turn gorgeously and become a small-caliber semi-automatic rifle. If the accuracy can be guaranteed, Yang Tianfeng also wants to install a scope for it and use it as a sniper rifle!

"And-" Yang Tianfeng learned from Li Jianye's appearance just now, and deliberately paused for a moment before smiling and saying: "The arsenal should add a new regulation, and the talents who can make improvements in production processes and processes and improve production efficiency should be rewarded." You will work out the specific reward standards as soon as possible and announce them for implementation. ”

Li Jianye thought for a while and said, "The treatment is already quite good, and you still want to be rewarded?" Of course, the chief wants to increase the enthusiasm of technical personnel for innovation, so I will set the reward lower, and if there is, it will be fine. In fact, everyone really doesn't care whether there is a reward or not, as long as they can contribute more to the war of resistance, they are very happy. ”

"I know everyone's enthusiasm for work." Yang Tianfeng nodded lightly and said, "The reward, as you said, is an encouragement, and it also shows my gratitude and that of the front-line soldiers." Without your hard work, there would be no weapons and ammunition to fight devils, and there would be no constant victories. ”

After studying and discussing with Li Jianye and other technicians, Yang Tianfeng had a working meal with everyone before leaving the arsenal and ending the inspection and guidance.

The human heart is available! Contributing to the War of Resistance, fighting devils, and protecting the homeland were the themes of the times at that time, and they also permeated the body and spirit of every conscientious Chinese.

Bathed in the sun again, Yang Tianfeng let out a heartfelt sigh.

………………

Time flies quickly, and although the yellow straw in the field is still standing, the chill of winter is getting stronger.

And in the cold of this early winter, the news of the victory in the Battle of Changsha came from the rear. Chongqing's propaganda machine is at full speed, wave after wave to celebrate the "great victory in Changsha," and meetings from all walks of life are frequently held.

Due to Yang Tianfeng's intelligence, the victory in Changsha did have greater results than in history, killing and wounding more Japanese devils.

However, there were many reasons for the defeat of the Japanese army, underestimating the combat effectiveness of the national * army, ignoring the adverse effects of the mountainous terrain of northern Hunan Province, and the most important reason was ignoring the strength of the Chinese people.

Before the battle began, the local people, under the organization of the government, cooperated with the Chinese army to destroy the main communication arteries between the Xinqiang River and the Laodao River, and even the land between this area was turned over and became new soil, so that the Japanese mechanized troops could not be used, the heavy artillery was difficult to follow, its combat effectiveness was greatly weakened, and even the logistics could not be completely guaranteed.

By the time the Japanese army came to the vicinity of Changsha with great hardships and heavy casualties, it was already exhausted and the supply of food and ammunition was close to being cut off.

The commanders of several divisions of the Japanese army were veterans of a hundred battles, and they were the first to smell the smell of danger and told Okamura Ninji to retreat. When Okamura Ninji was in a dilemma, he received a reconnaissance report from the plane, and on the front line of Changsha, about six elite divisions of the National * Army had been assembled.

Previously, Okamura Ninji was quite puzzled by the fact that the Chinese army suddenly stopped holding its position and adopted a more flexible tactic of fighting and retreating, while the Japanese army was constantly ambushed and blocked. , at this time, it suddenly dawned on me. It turned out that Xue Yue's purpose was not to hold Changsha, but to try to completely defeat his mid-lane attacking army.

If we continue to storm Changsha regardless of it, as long as we are undefeated for a few days, the combat effectiveness of the troops is exhausted, and there is no supply, at this time, the Chinese army will concentrate its main forces to give a head-on attack, will it not face the catastrophe of annihilation?

I have to say that Okamura Ninji, an old devil, has a pragmatic and good quality, and he weighed the weight and decided to take the great risk of bearing the charge of defeat and let all the troops retreat.

In fact, this determination is very difficult to make. Perhaps for other soldiers around the world, victory and defeat are commonplace, and there is nothing to be ashamed of advancing and retreating. But for the so-called Great Japanese Locust Army, the word "retreat" has never been in the dictionary. Before he said that he would occupy Changsha in September, but now he retreated at will, which is the blowing of the cowhide and the extreme humiliation.

On October 1, Okamura Ninji urgently ordered an immediate halt to the offensive, and the troops gradually returned to the north of the Laodao River. However, even so, the Japanese army still drilled most of its body into the pocket formation of the national * army. Although there was no devastating defeat near Changsha, it was not easy to retreat more than 100 kilometers north.

Okamura Ningji's decision to withdraw his troops was so unexpected that Xue Yue, after receiving the report of the Japanese army's retreat, couldn't believe that it was true, and he was still waiting to fight his opponent in the suburbs of Changsha!

Seki, who was on the front line, noticed signs of the Japanese retreat, and immediately ordered all units to follow up and attack the enemy retreating from Uesugi City. On October 2, the units of the 15th Army began a pursuit, and on the same day the city of Uesugi was recaptured. three days; The 25th and 195th Divisions pursued to the vicinity of Fulinpu and Jinjing, and the Japanese army began to retreat to the north bank of the Miluo River; On the 4th, the 15th Group Army regained Changle Street, Miluo, Xinshi and other places.

It was only at this time that Xue Yue concluded that the Japanese army was indeed retreating, so he hurriedly issued an order, requiring all units to "immediately pursue the enemy in front of them in the present situation, and to capture the area south of Chongyang and Yueyang", and "to send a unit to monitor and sweep the enemy's containment troops, and the main force should surpass the pursuit."

After receiving the order, the troops of the Nationalist Army, which had implemented the method of retreat and opened the main road and guarded both sides, assembled and appeared, dispatched from the mountains and forests, and constantly attacked the retreating Japanese troops. Behind them were the fiercely pursuing Nationalist * Army troops, and there was a certain degree of confusion in the various units of the Japanese army. Although the Japanese army did not collapse due to its good quality, it was very embarrassed due to the constant ambush and pursuit, coupled with the exhaustion of supplies.

Take the 102nd Division of the Guizhou Army as an example, the division chased the Japanese army with two regimental tails! Attacking from Changsha, they chased more than 100 kilometers. At that time, the Japanese army was patronizing and retreating, and they did not dare to stop and fight. As the weakest combat unit in the national army, the Guizhou army was extremely poorly equipped, but it also killed and wounded hundreds of Japanese soldiers, which shows how panicked the Japanese army's retreat was.

On October 6, Okamura Ninji declared that the purpose of the operation had been achieved, and the battle was over. But at this time, there were still many Japanese troops running and not retreating across the Xinqiang River. It was not until 8 October that the Japanese army retreated across the Xinqiang River and returned to its own defense area, and the Nationalist Army recovered all the lost ground.

At the end of the First Battle of Changsha, both the Japanese side and the Chinese side announced the results of their own statistics: the Japanese side claimed that more than 48,000 people were killed, wounded, and captured in the battle, while the Japanese casualties were only 3,600; The Chinese side claimed that the Japanese army had suffered more than 30,000 casualties and that the number of casualties in the Ninth Theater was more than 40,000.

The casualty figures are all water, and Yang Tianfeng doesn't care much about it. However, judging from the strategic and tactical aspects of this battle, as well as the final result, there is no doubt that the national army will achieve victory.

Strategically, the Nationalist Army lured the enemy into depth and resisted one after another, resulting in the gradual depletion of the Japanese army's combat strength, so that in the end it did not achieve the goal of annihilating the main force of the Nationalist Army of the Ninth Theater and failed to achieve the goal of occupying Changsha.

Tactically, the Kuomintang mainly focused on defense and relied on the favorable terrain of the Xiangshan Mountains, causing heavy casualties to the Japanese army. Then, the decisive battle of retreat was adopted, destroying communications and clearing the fortified walls, resulting in the inability of the Japanese army to give full play to its advantages, its combat effectiveness was greatly reduced, and the logistical supply was almost interrupted, and finally it had no choice but to retreat.

It's a pity that I can provide the deployment of the Japanese attack, but I can't determine the time of the devil's retreat. Well, it's not that it's impossible to determine, but it's too incredible.

Yang Tianfeng was sorry that Xue Yue couldn't make the judgment that the devil retreated earlier, but this was also something he couldn't do.

And now, he has shifted all his energy to the military, preparing to switch from defense to offense, and grasp the initiative.
