As a result, the Soviet Union's offer for the introduction of talents is not high, and on the premise of working in China for three years, the average head of each person is only about 1,000 US dollars (but we have all the food and lodging included), which is much cheaper than hiring from Western countries, but the problem is that the Soviet Union itself now has a total of less than 1 million scientific and technological experts and senior technicians, and if 200,000 are sent to China, it will be difficult to ensure that the operation of the Soviet Union's domestic economy and even national defense construction will not be a problem, so it is easy to say that it is only willing to send 100,000 people, so the 200 million US dollars will only be spent.

The purchase of JISHU equipment was even smoother, and it only cost less than 100 million US dollars to get all the JISHU equipment we needed. On the one hand, this is because after Hu Weidong's efforts in the past two years, the current level of jishu in the border area has been quite high, and many fields are even stronger than the West, and the Soviet Union is even more incomparable, and after the problem is solved, even if it is to be introduced, Hu Weidong also advocates starting with the West with a higher level of jishu as much as possible, and there are not many jishu equipment that the Soviet Union can make him tempted. On the other hand, it has to be said that the Soviet Union really showed sincerity this time (Note 1), although the top core jishu was still reluctant to transfer, but the slightly inferior ones not only gave the green light, but also offered a fair price, for example, a freestyle hydraulic press with a nominal pressure of 8,000 tons only cost 5 million US dollars

As a result, more than $300 million was left unspent on the loan, which Hu Weidong had intended to use to purchase rare metals from the Soviet Union that China lacked. Although it is not as urgently needed as jishu equipment, it is definitely not a loss, after all, sooner or later it will also need to be imported in large quantities from foreign countries

However, now Hu Weidong has changed his mind and plans to take out some of them to directly purchase planes from the Soviet Union to fill the vacuum after the withdrawal of the Soviet aid air force and the Soviet anti-aircraft artillery unit and before the Jian-1 is finalized and put into service. However, the more important reason is that the Soviet Union's I-16 fighter has surpassed Japan's active aircraft in performance after continuous improvement over the past year, if it is still an early I-16 fighter with garbage performance. Coupled with the fact that most of the pilots in the border areas have no actual combat experience, the air combat exchange ratio must be ugly, and it is not easy for China to train a little pilot, but it cannot withstand such consumption

As Hu Weidong expected, the Soviet side was worried about overstimulating Lao Chiang, so it did not agree to sell bombers, but Hu Weidong originally wanted to buy only fighter planes, after all, the performance of Soviet bombers was average, and second, even if he bought Soviet planes. The overall strength of the Chinese Air Force is still not comparable to that of Japan, and air supremacy cannot be guaranteed. The fighter is significantly more cost-effective.

Because of the importance attached to the training of pilots all along, and the fact that over the past two years, more than 1,000 young overseas Chinese with flying experience have returned to China to join the North China Aviation Corps, and the total number of pilots and flight cadets in the border areas has reached no less than 3,000, and the balance of the loan is very large, so Hu Weidong's appetite this time is quite large, and he actually issued a large purchase order for a whole 3,000 fighters, and all of them are the latest modifications of the i16 fighters.

But the Soviets themselves do not have so many I16-24 (that is, the 24th modification of the I16) fighters now, so it is naturally impossible to agree, after the efforts of the Chinese side to negotiate. Zuihou agreed to sell 1,200 fighters of this type to the Red Party and deliver them within three months (the total Soviet production exceeded 12,000 the following year), but the gyroscopic sights and turbochargers were purchased by the Chinese themselves. In addition, the Soviet Union also provided 600 trainer planes to the border areas to support the Red Party in building a new aviation school in Lanzhou and Dihua. Since then, the overcrowding situation of Luoyang Aviation School has been alleviated, and because the two new aviation schools are farther away from the front line of the Anti-Japanese War, the safety is much better.

The total amount of the deal is as high as $80 million. But it is fair to say that Maozi's offer is quite kind, because the Soviet Union also provided a large number of parts for repair and replacement, and then thinking about Maozi's attitude towards the Red Party before the Anti-Japanese War, Hu Weidong couldn't help but sigh secretly. "Sure enough, you still have to have strength to be respected!"

Lao Jiang naturally jumped like thunder when he learned about it, but the Soviet Union is now growing in national strength, even the United States and Britain are afraid of it, so he can only knock out his front teeth and swallow it in his stomach

Even after completing such an arms purchase, there was still a balance of more than $200 million in the loan, and Hu Weidong used all of it to purchase those mineral resources that the Soviet Union had abundant reserves but China lacked, the most important of which were rare metals such as chromium, cobalt, and nickel. Thankfully, the border region also bought a large amount of uranium from the Soviet Union

Although at the beginning of 1939, the German chemist O. Hahn and the physical chemist F. Strassmann published a paper on the fission phenomenon of uranium nuclei, which revealed this secret, but at first the great powers did not attach great importance to it, and the Soviet Union due to the overall poor level of science and technology, has been adopting a "follow-up" strategy, that is, until the West began to study, Mao Zi followed the trend, in order to reduce the waste of scientific research resources, so at first the export of uranium ore did not pay much attention to it, As a result, by the time the Soviet leadership noticed this problem, the uranium ore purchased by China from the Soviet Union was calculated in terms of the uranium metal it contained, and the total amount of uranium-235 contained in it was enough to make two or three hundred nuclear warheads (of course, because reactors and research were also needed, it was practically impossible to build so many, but China did not only obtain uranium ore from the Soviet Union, which has already been mentioned earlier, so I will not repeat it), Stalin executed all the cadres of the relevant departments for treason in a fit of anger, But the uranium ore that was sold will never come back

After the capture of Qingdao, the 15th Group Army once devoted most of its energy to air defense and suppressing bandits, and by the way, let the troops carry out rare repairs and training, but after Fu Zuoyi's 35th Army joined the formation, even if the 15th Group Army was only a field army, the total strength exceeded 250,000 people, and it was not Hu Weidong's style to have such a strong strength but did not take the initiative to attack, but just when Hu Weidong was thinking about where to fight next, the Fifth War Zone suddenly sent a telegram asking for help directly to the former enemy command of the First War Zone in Qingdao. There was no time to even report to the Military Commission first, and it was obvious that the situation was extremely critical

Note 1: Realizing the strength of the Red Party, the attitude of the Soviet Union, which was originally more oriented towards the government, gradually began to change. In addition, because the Soviet Union was stronger in this time and space than in the same period in history, Western countries were particularly hostile, which made the Soviet Union feel isolated in the international community, which may be the main reason why Mao Zi showed favor to the Chinese Red Party.
