The sound of the plane's engine came from the sky behind him, and the Far East soldiers in the trenches cheered thunderously towards the sky. Over the Yenisei River, fierce air battles occurred almost every day. A fighter of a National Defense Force could withstand 3 or 4 Soviet I16 fighters. In a few days, the sky almost became the world of the Far East Defense Force.

The Soviet army sent a large number of reinforcements, and some new MiG-3 fighters also began to participate in air combat. Due to the failure of the Far East Army to supplement the losses in time, the two sides returned to a state of equal strength. However, in general, the Far East Defense Forces still maintained a certain advantage.

A huge spiral column of smoke rose in the distance. In the telescope, you can see the sky-sky fire caused by the "Stuka" bomber dropped bombs on the enemy's positions. Flashes of fluctuations also came from the earth, which seemed to be likely to detonate the Soviet ammunition depot.

The Far Eastern Defense Forces were still confronting each other on the Yenisei River, but on the southern front, the Soviet army crossed the West Sayan Mountains, crossed the Kemuqik River, and entered the territory of the Tanuwulianghai in China.

China only has one border guard cavalry brigade in the Tanguwulianghai, which can no longer stop the attack of the Soviet army's 200,000 troops. Now, only the rugged mountains of the Tanguwulianghai can be delayed.

The Soviet invasion immediately involved China in the war. While conducting diplomatic negotiations with the Soviet Union, the Beiyang government mobilized its military forces to expel the invading Soviet army.

From the perspective of historical evolution and administrative jurisdiction, Tanu Ulionhai and Kobdo have never had any affiliation with Khalkha Mongolia in Kulun. Since the establishment of General Ulya Sutai in the Qing Dynasty, it has been under the management of the Minister of Kobdo Service. Since the Kulun authorities abolished their autonomy, the Beijing government ordered Kobdo and Tanu Ulionhai to be arranged from Outer Mongolia and juxtaposed with Altai as Kobdo Province, and the capital was set in Kobdo City.

The construction of the Northwest Railway made the transportation between Kobdo and Suiyuan convenient. In addition, the Suiko Railway leads to the ancient city and Dihua on the south side of the Altai Mountains, becoming another major railway artery connecting Xinjiang in the mainland. With the completion of Suiyuan to Kulun and Shangwujinsk Railway, Suiyuan City became the most important railway hub in the northwest and rapidly developed into a large central city with a population of one million.

However, now, almost all civilian trains from Suiyuan to all parts of the northwest have been suspended, and the Beiyang government is making every effort to increase troops to Xinjiang, Kobdo and Kulun. The entire station is full of military trains loaded with soldiers or military supplies, and all stations along the way are martial law and will be taken over by the military. Ordinary people cannot enter the station without a special letter of introduction.

The large civil airport located outside the city of Cobdo was completely taken over by the military at this time, and hundreds of trucks were transporting the military supplies they had just arrived from the train station overnight.

"Quick! Assemble the plane quickly!"

The packaging wooden box was opened, revealing the disassembled metal aircraft, wings, noses, fuselages, tails, engines and other parts were packed into different packaging boxes. Nearly a thousand mechanics and ground crews were busy and started the assembly of fighter jets directly on the concrete runway of the airport. These Army Air Force officers and soldiers were in groups of more than a dozen. Under the command of the mechanic, they carried the large structural parts of the aircraft to the ground and arranged in sequence. Looking down from the airport's command tower, the outlines of the disintegrated fighter jets can be distinguished.

With the strong support of Austro-Hungary, the Beiyang Army has been greatly strengthened since 1934, and all old biplanes have been eliminated as training aircraft for aviation schools. 650 latest fighter jets and bombers were imported from Austro-Hungary, and then they copied about 1,100. Currently, the Beiyang Army Air Force has more than 2,500 combat aircraft, and the Navy Air Force has nearly 800 combat aircraft.

The Army Aviation was reorganized and organized into 12 hybrid army aviation divisions, each with 2 fighter aviation regiments and 12 bomber aviation regiments. The Navy Aviation regiments were organized into a flight wing, which was basically the same as the Army Aviation Division. Now the Beiyang government has deployed about half of the domestic air force to Mongolia, Kobdo and Xinjiang provinces. Each province has deployed two aviation divisions. In order to resist the Soviet invasion, the government has done its best to send the only three armored divisions in the country to the north.

The combat deployment formulated by the General Staff Headquarters is: the front line of the West Xinjiang, with a total of 12 divisions, including one armored division and two aviation divisions. The total force is 260,000, Wang Xiaozhen is the commander-in-chief of the West Road Group, and Li Jingrong is the chief of staff. The front line of the Central Cobudo, a total of 10 infantry divisions and 210,000 people, including two aviation divisions, commander-in-chief Wu Guangxin, chief of staff Wang Jianming. The front line of the East Road Kulun, a total of 13 divisions, with a total force of 280,000, including two armored divisions and two aviation divisions, commander-in-chief Jiang Yanxing, and chief of staff Zhang Chengli.

The 6th Army Air Force Division is now assembling the aircraft at Kobdo Airport. This division includes two fighter flight regiments and two bomber flight regiments, with a total of 296 combat aircraft. Among them, the 20th Fighter Aviation Regiment is preparing to replace the 72 latest F5 Thunderbird fighters assisted by Austro-Hungarian aid. Due to the urgent situation, these new fighters were transported directly to Kobdo by railway without unpacking the box after they arrived in Tianjin Port.

"Oh, it's the latest 'thunderbird'!" Colonel Robeck, the Austro-Hungarian military adviser of the 6th Army Aviation Division, couldn't help but scream in surprise when he saw the fighter plane being assembled.

"Oh, Colonel, what's there to be surprised?" Yang Hongding, the commander of the 20th Fighter Aviation Regiment, who accompanied Colonel Robeck to supervise the installation and commissioning of the aircraft, asked, "The fighter jets made by Austro-Hungary Standard Airlines are almost the same in appearance, and the first fighter jet that has been assembled at the airport is preparing to start commissioning.

"No, different. This is the world's first aircraft with a speed of more than 600 kilometers. It is equipped with a 1,070 horsepower 12-cylinder inline liquid-cooled engine. It reached 627 kilometers per hour during the test. At present, the imperial aviation troops are only equipped with a small number, and they did not expect to be given priority to China." Robeck said, "The Thunderbird's firepower is strong, equipped with 2 20mm cannons and 2 12.7mm machine guns. The firepower of the fighter jets is much stronger than previous fighter jets. The Soviet fighter jets are not its opponents at all."

"Haha, after you say that, I have to go up and experience it myself." Yang Hongding smiled, "According to the combat plan, we will attack tomorrow."

"I want to give it a try, too," said Robeck.

"Don't, the General Staff's order is to strictly prohibit technical experts from boarding and flying unless you can apply for the qualification of a volunteer pilot." Yang Hongding said that there is no need to say about the skills of German and Austrian military consultants, but they just want to fly the plane for testing in person. This is an old headache.

"Okay, okay, I wish you can build such a plane earlier or even earlier."

“Is it difficult?”

"Of course, besides Germany and Austria, have you heard of which country can build an aircraft engine with more than 1,000 horsepower?!" Robeck said proudly with his head raised,

"But I heard that the British PV12 engine has exceeded 1,200 horsepower." Yang Hongding said, deliberately hitting Robeck's arrogance.

"#...￥&￥*...%, damn British guy!" Robeck couldn't help but swear, but his next sentence made Yang Hongding have nothing to say, "Yang, at least you want to copy it. In less than two, it's absolutely impossible to do it in three years!"
