Light energy oil recovery is useless, because crude oil cannot be used directly, but fortunately, the last time the British Bell left the Soviet area, Hu Weidong entrusted him with oil refining equipment in the list of purchases, which was intended to be used to try to refine shale oil. Although it is not completely correct, the equipment that can refine shale oil is naturally not a problem for crude oil that is easier to handle, but the production capacity is probably less, after all, Hu Weidong did not expect to take Nanyang so quickly.

In late July, Bell, who has become a millionaire, came to the Soviet area for the second time, but the goods he brought made Hu Weidong a little disappointed, and many of the equipment he wanted, especially the large equipment necessary for the backbone industry, was not available, but Bell did not want to make money, but the machine that was too large could not pass through the national control area safely, in fact, he still has dozens of large machine tools, generators and other large and medium-sized machinery and equipment forced to stay in Lianyungang, and the oil refining equipment is too large He has long expected that he will not be able to pass and did not buy it, the result was really guessed by him, thus avoiding unnecessary losses

But Hu Weidong was very angry about this, he solemnly warned Bell, "If the large items can't be shipped in, they can be disassembled into parts and transported in, and there is really no way, we can also send people to the national control area to receive them, and whether they can be shipped here is our business, but you are doing this now, which makes us doubt your sincerity to continue to cooperate!" ”

Bell was still smug about his cleverness just now, and when he heard Hu Weidong say this, his expression suddenly fell, if the other party was angry and refused to sell him penicillin. So wouldn't the money he saved become "picking up sesame seeds and losing watermelons." ”？

Fortunately, Bell's self-assertion is not all self-made cleverness, he bought a large number of precision measuring tools by himself, so happy that Hu Weidong almost slapped his thigh on the spot, precision measuring tools are a necessary prerequisite for precision machining. How did he forget all about that? Moreover, what made him even happier was that the vernier calipers, thermometers, thermocouples, barometers, and analytical balances brought by Bell this time were all high-quality products purchased from Germany or Switzerland, which would undoubtedly be of great help in improving the technological level of the Soviet industry, especially the military production. However, Hu Weidong obviously will not be satisfied, he took 300,000 sticks of penicillin as a deposit, and asked the Beltisu District to go to Europe to purchase the machinery and equipment needed for the production of these measuring tools, and hire some skilled workers and experts as much as possible, if it is done well, 1 million or even more penicillin is not impossible

In addition, after learning that Bell had opened his own import and export trading company. Hu Weidong asked him for the identity of the Far East division manager of the Bell Trading Company as a cover, so that he could go abroad in the future. After getting another 300,000 pieces of penicillin, which was more expensive than gold, Bell, who was full of spring breeze, happily guessed Hu Weidong's purpose and immediately invited Hu Weidong to go with him. With him as a foreign tycoon, he is relatively much safer. But Hu Weidong did not leave immediately, this is because Bell cannot be fully trusted now, after all, Hu Weidong's current status is not trivial, and he will carry a huge amount of more than 10 million pounds with him. He didn't want any surprises; Second, because there is still a period of time before the 1937 economic crisis, another economic crisis after the Great Depression, and it has not yet reached the best time to buy the bottom; Third, there is still some important work in the Soviet area, mainly in the military industry, that must be completed by Hu Weidong himself

First of all, the 30mm aircraft gun that Hu Weidong had considered as early as the North China operation, in order to cooperate with the high ceiling and high climb rate of the Type 95 biplane fighter. Employing a tactic tailored to grab the top position is enough to compete with the new Shijie advanced models in the next three or even five years. The production and manufacturing of aviation guns does not have particularly high requirements for equipment, technology and the quality of workers, and the number of needs is limited. It was possible to concentrate excellent craftsmen for finishing, so the project went very smoothly. An additional 3 aircraft guns were built for each aircraft to spare, but it was more troublesome for the modification of the Type 95 fighter and the corresponding flight training, but this was not Hu Weidong's job, Wang Zhu, Chang Qiankun and other aviation experts were responsible, and he was very relieved...,

Compared with this, the development of new firearms is more important, although the original Gongxian Arsenal has some punches, but the quality can not satisfy Hu Weidong, the production of semi-automatic rifles with low precision requirements is acceptable, used to manufacture machine guns and automatic rifles The scrap rate must be frighteningly high, so Hu Weidong only made the 24 type semi-automatic rifle and the 24 type submachine gun with lower production conditions. But this time, Bell brought a lot of high-quality punches made in Germany and chrome ingots, which were lacking in China, and the production of new machine guns and assault rifles was finally possible.

The gun type template chosen by Hu Weidong is the 81 type assault rifle and the 81 type squad light machine gun that have been tested in the war in later generations and the 80 type general-purpose machine gun that was born at the wrong time in history, and the names are all collectively called the 81 type xx, after all, these classic gun models will definitely be used for a long time in the future, and they are completely worthy of being named after the birthday of the people's army. However, Hu Weidong regretted that the Type 85 sniper rifle, Type 85 anti-aircraft machine gun and M99 anti-materiel sniper rifle in Jihua had to be temporarily shelved due to the higher production conditions.

The reason why the Type 81 assault rifle was chosen was because Hu Weidong knew much more about it than those famous foreign guns, and as long as the production conditions were met, it could be easily manufactured; The second is because this assault rifle is an outlier in the history of the development of shijie assault rifle, its single-shot shooting accuracy actually exceeds the 56-type semi-automatic rifle known for its high accuracy, this unique design idea is still because China was too poor at that time, it is impossible to waste bullets like the United States and the Soviet Union, but it is more in line with the current situation of China's weak and poor people during the Anti-Japanese War. Bullets can be greatly saved.

Note 1: This gun model is imitated by the former Soviet Union PKMC 7.62 mm machine gun, and its performance and cost are better than the 67-2 type heavy machine gun that was later equipped with a large number of domestic troops, but due to other reasons such as equipment inheritance, the competition failed, but it has become one of the fist products exported by our army, and it can be regarded as "blooming in the wall and fragrant outside the wall". Its biggest advantage is that it is extremely lightweight, the whole gun weighs less than 9 kg, which is even lighter than the Czech light machine gun, especially suitable for the Chinese army, which generally had to walk on its feet during the Anti-Japanese War
