After dealing with the mess of the fertilizer factory, Qin Lang rushed to the Zhongshan Research Institute again. Pen? Interesting? Pavilion wWw. ｂiquge。 info It is located in an inconspicuous hill pass, which has now been classified as a military restricted area by the Security Bureau, and there is no way for idlers and others to approach it.

As soon as I entered the mountain pass, I heard the sound of continuous shooting.

I saw a heavy machine gun spewing flames, and a steel plate in front of it had been smashed by powerful machine gun bullets.

"Click!"

At that moment, the shooting stopped. The technician next to him immediately got busy. But the machine gun did not fire again, and something tricky should have gone wrong.

Zhong Cheng, who received the news, rushed over, and when he saw Qin Lang, he said:

"The 12.7mm machine gun is really not easy to serve, and it can also be shot with the structure of the Type 28 general-purpose machine gun, but the requirements for bullets and propellants are too high, and the cost is not something we can afford. In the end, it was decided to use the structure of the Browning A1919, which is still being explored, and it will take at least a few months to finalize! ”

Qin Lang waved his hand.

"I can't eat hot tofu in a hurry, we're making up for the past lessons. Comrade Zhong Cheng, it doesn't matter if the development is slow, the key is to be reliable and not make any mistakes. What's wrong with the rifle that was sent, have you found out? ”

In other units, the feedback from the 28 semi-automatic rifles was quite good, and there were no problems with the 1st brigade, which made people feel strange.

Zhong Cheng Rong says:

"The problem with the gun has been found out, and the situation is serious. Commander, this time because of my dereliction of duty, there may be a large number of guns to be eliminated, and I ask the organization to punish them! ”

This sentence made Qin Lang's face change.

The mass production of the 28 semi-automatic rifle was enforced by Qin Lang, and it was constantly questioned in the red zone. For this reason, after completing the production task, even he made a guarantee of "not taking an example"! But no matter how big the problem is now, it can't be uncovered by an inspection.

"What the hell is going on?"

Zhong Cheng hurriedly said:

"Commander, the problem is in the barrel. The steel used for the 38 big cover and the 44 type riding gun was, after all, a craft from the early twenties, and the rifling of the barrel was not chrome-plated. The Arisaka bullet used by the devil is a copper-coated lead bullet, and it has extremely low wear and tear on rifling, so there will be no problem with using old-fashioned bullets.

And we are using steel core bullets, which wear much more on the rifling. Because of some of the requirements of automatic rifles, the propellant also had to be greatly modified. We are now using German technology, and the propellant burns quickly, which is relatively large for the ablation of steel.

Usually the soldiers are well maintained, and this problem is difficult to expose. But after the continuous operation of the first brigade, the guns were not maintained. Rifling wear, coupled with gunpowder ablation, this batch of guns went wrong. ”

Qin Lang asked:

"Is there a solution to this?"

Zhong Cheng says:

"The only solution is to replace the barrel, which is not imminent, after all, there will be no problem under 3,000 rounds. Today, the gun steel of the steel mill has met the needs, and if the chrome plating process is added, these problems can be solved. It's just that the cost has almost tripled, and the number of man-hours for the production of barrels will increase, and the number will drop significantly, perhaps less than 3,000 per month. ”

Qin Lang secretly breathed a sigh of relief.

"Inform the arsenal to step up the replacement of the barrels of those rifles, and gradually recycle the old guns in the hands of the soldiers. Zhong Cheng, what else is the feedback from the 28 semi-automatic rifle? ”

Zhong Cheng shook his head.

"Basically, there is no problem, some fighters want to change to magazines, these reloads are more convenient. It's just that the various metals in the red zone have been counted in detail, and the current holes are too big, and the ones who use the magazine are really inadequate. ”

The blast furnaces of the steel mills are already overloaded, but it is unlikely that the red zone will add more steel plants because the iron ore used is too dependent on imports. In particular, the rich iron ore of the Soviet Union already accounts for 70% of the use. Winter is now approaching, and trade will be cut off within a few months. At that time, as long as the domestic poor ore can be used, although the sintering process has been used, the output will definitely drop significantly.

Qin Lang sighed and said:

"It's time to talk to the young marshal, the Beijing-Zhangjiakou Railway must be kept unblocked!"

The scheduled scrap steel was piled up at Citi's port, but it could not be shipped back to China. Now the red zone is relying on the 200,000 tons of steel that was hoarded before. As the project progresses, this material can only be supported. All completed and put into operation, 500,000 tons are not enough!

Of course, Zhangye's open-hearth furnace can also make steel, and it can even reach 200 tons per day, and the amount of iron ore used, not to mention the current China, even the Soviet Union and Russia are not enough for trade. And for those old equipment, the coke consumption alone is a staggering figure, far less affordable than scrap steel.

Just as Qin Lang was thinking about a solution, a herald hurriedly ran over.

"Report to the commander, an urgent telegram has been sent from the headquarters organs, the Hunan and Jiangxi Military Region has smashed the third anti-encirclement and suppression under the leadership of the chairman, and now the scope of the red zone has been expanded again, and the headquarters organs are preparing for the establishment of the Chinese Soviet Republic!"

Hearing this message, Qin Lang's face turned pale, and he asked in a deep voice:

"Are there any other messages?"

The herald replied loudly:

"Report to the commander, there is also a telegram specially sent to you, in which the headquarters organ demands that the Jicha Suihong District continue to persist in fighting against the Japanese and resolutely crush the offensive of the reactionaries. If the situation is dire, the commander must adapt to keep the flame of revolution alive! ”

Jicha Suihong District is indeed not an ideal place, the territory looks not small, but the population is less than 2 million. Nearly a million Kuomintang troops coveted it in the vicinity, and they are still fighting against the Japanese army.

And the results of the recent military struggle have taken the members of the General Headquarters by surprise. Because the attrition of the Jicha Suihong District has exceeded the most pessimistic projections. Seeing the heavy losses of the Red Army soldiers, most of the commissioners even asked Qin Lang to retreat at the right time. However, the devil temporarily stopped the offensive and eased up.

But this battle also made many people understand that the devil soldiers are not easy to deal with. And the previous deduction of the Jichasui Military Region did not exaggerate the enemy's strength. In the next step, when the devil's troops were directed at Inner Mongolia, the Jicha Suihong District could only shrink to Suiyuan.

And Zhang Shaoshuai's offensive against Zhangjiakou also shows that Suiyuan is not safe. If the Red 50th Army and the Red 51st Army could not hold it, they could only retreat to Gansu. But the situation there was even worse, and after the drought the people were already destitute and could not afford to maintain so many military and political personnel. And the original Yang Hucheng Department now has the territory of Shaan'an Province, and now he is eyeing Gansu, and he also has hundreds of thousands of male soldiers under him.

Qin Lang said in a deep voice:

"Reply to the headquarters organs, and resolutely obey the orders of the headquarters organs in the Suihong District, and fight the enemy to the end!"
