In fact, the performance of the Stern type, especially the poor reliability, is compared with Bobosha and other famous guns of World War II, but compared with the main submachine gun of the Red 15th Army - the first Shijie submachine gun MP18 born in the First World War period of the Chinese copycat version of the "Flower Mechanism", the advantage is very obvious, its compact appearance and light weight make it have excellent flexibility, low recoil makes it very advantageous when moving and attacking in the battlefield, the rate of fire and power are also above the "Flower Mechanism", and its production cost is only" one-tenth of the flower organ, which made Liu Ding, who was now in charge of the work of the Soviet District Arsenal Jishu, immediately give up the original production of the "flower organ" Jihua, and instead devoted himself to the testing, inspection, finalization and production of this "new" submachine gun, and Hu Weidong did not use any advanced jishu to easily design such a useful weapon, so that Liu Ding couldn't help but admire the five bodies, and he stole from someone's famous saying, "To design a weapon is very complicated, this is a very simple thing, But designing a weapon is very simple, but it is extremely complicated. It has had a profound impact on Wu Yunduo and other young military cadets

Although the successful production of the Stern submachine gun made the arsenal jubilant, Hu Weidong did not pay much attention to it, and did not even name it, but simply called it a "border made" submachine gun. Because the design of the Stern submachine gun was very hasty in history, there were many major flaws, such as bullets that were easy to jam and easy to misfire, and they would kill people in actual combat. In addition, the ammunition used in the Stern submachine gun is the most popular 9×19mm Luger pistol cartridge in Europe and the United States, but in the Chinese battlefield, because of the popularity of box guns, the most common pistol cartridge is the 7.63x25mm Mauser pistol cartridge. Considering that the submachine gun was a large consumer of bullets, and capture was still very important to the Red 15th Army, Hu Weidong hoped to change the caliber of the Stern submachine gun to 7.63mm, and adjust the design accordingly, so as to use 7.63x25mm Mauser pistol cartridges, and it would be better if he could directly use a twenty-round magazine. Since Hu Weidong was not an expert in firearms, he gave this important task to Wu Yunduo as his first test. However, considering Wu Yunduo's current age, Hu Weidong did not put too much pressure on him, not only was the time relatively relaxed, but also allowed him to make any changes to this gun model without increasing production costs and reducing production speed, giving this teenager great freedom

Because the production process of the Stern submachine gun was too simple, if the Soviet Arsenal put half of its manpower into it, it would be able to produce at least 1,000 pieces per month, but unfortunately because the production of bullets could not keep up, and this gun type was only a short-term transitional product in Hu Weidong's eyes, so in the end only a small part of the manpower was allocated, producing 5-10 pieces per day. But even so, this "border-made" submachine gun greatly enhanced the melee firepower of the Red 15th Army, which was especially obvious in street fighting

Although the Soviet Arsenal ushered in a blowout period since its establishment, to Hu Weidong's regret, when he made persistent efforts to build a production line for the mass production of artillery shells of various calibers, he encountered several difficulties that were difficult to overcome: First, there was a lack of necessary machinery and equipment; at present there were only a handful of arsenals in China with this production capacity, and although the Red 15 th Army was strong, it was not arrogant enough to dare to go to Shanghai, Nanjing, Taiyuan, and other big cities to spread wild; Second, the mass production of artillery shells requires far more key raw materials such as explosives and mercury than the production of bullets, and it is difficult to meet the demand by seizure alone; Although there is no talent to train, the leaders of the Fujian, Zhejiang, and Jiangxi Soviet regions basically have little energy to popularize education in the base areas, and most of the dozen or so counties in the Fujian, Zhejiang, and Jiangxi Soviet regions are barren and backward mountainous areas, and the literacy rate of the common people is lower than the national average, less than 10 percent. This efficiency made him really speechless, he still had to go north to resist the Japanese as soon as possible, how could this be too late? …,

"It seems that when the Red Army lost the Central Soviet Area, it lost more than just a piece of territory," Hu Weidong sighed, and he was deeply glad that he had the foresight to take away almost all the educated youths in the old Soviet area, and at the same time strengthened his determination to "rob" talents everywhere he went, "even if I am infamous because of this, I must accelerate China's modernization and industrialization as much as possible"

At the same time, Lao Jiang, who was far away in Chongqing, was forced to order the national army of Fujian, Zhejiang, and Jiangxi provinces to turn from offensive to defensive because of the huge losses of the national army, especially the Central Army, and urgently summoned Xue Yue, a famous general who was responsible for chasing down the Central Red Army and taking the opportunity to get rid of the warlords in Guizhou, and asked him about countermeasures, "Boling, now the Zhumao Red Army is at the end of its life, but the Jiangxi bandits have resurged, and the momentum is very loud, you should have heard of it, right?" Fang himself is pressing forward step by step, if he doesn't first put down the red bandits, stabilize the country, and gather the strength of the whole country, how can he confront the Japanese? But I can't imagine that this red bandit is so difficult to suppress, I don't know what Boling thinks about this? ”

In fact, there are few people in the top echelons of the Kuomintang who do not know that the rise of the Red Army is mainly due to the political problems of the national government, but Xue Yue, now as a heavy general in command of 200,000 troops, is not easy to get involved in politics, he just gave his own analysis on the military alone, "Commission, if the war reports and rumors are correct, this red bandit is not simple, if there are fewer troops, not only can they not be destroyed, but on the contrary, a large part of the captured national soldiers may be bewitched by it, and its strength will expand rapidly like a snowball." Therefore, either you don't fight at all, or if you want to fight, you have to be sure of victory, and it is best to use the momentum of lions fighting rabbits and concentrate an army of 300,000 or even 500,000 to exterminate it in one fell swoop. ”

Lao Jiang frowned suddenly, although the total number of the national army is claimed to be several million, but the imaginary number of empty salaries is not a small number, and the actual strength is more than 2 million, of which more than half are local miscellaneous cards that he cannot fully control, and among the one million Central Army, 200,000 elites followed Xue Yue all the way to pursue the Central Red Army in the Long March, and another hundred thousand people are blockading the Hubei-Henan-Anhui base areas, and at the same time, the Red Army guerrillas led by Xiang Ying, Chen Yi and others who stayed in the Central Soviet Region also occupied more than 100,000 troops. In addition, the Red Army base areas in northern Shaanxi also attracted a lot of national troops, and at least the central cities always needed to send regular troops to garrison, and some troops had to be set aside to deter local warlords and prevent the Japanese from causing trouble again, and in just a few months, the Red 15 th Army wiped out more than 100,000 people, and the national government now let alone 500,000 or 300,000, even if it is 200,000 mobile troops, it is difficult to draw them out immediately. Thinking of this, Lao Jiang tapped his middle finger on the conference table with some irritation, "Do you just ignore them?" ”
