"The 4th Army Corps and the 5th Army Corps retreated on all fronts, Tang Yulin led his troops to flee south, and Rehe was in danger!"

"The 15th Route Army marched day and night, galloped to the aid of Chengde, and fought fiercely with the Japanese cavalry on the streets of Chengde, more than ten horsemen fled in a hurry, and the remaining more than 110 horsemen were annihilated. Chengde recovered! ”

The loss and recovery of Chengde made everyone's hearts relieved, more than 100,000 Northeast troops retreated, and the speed of the Japanese army attacking the city and grabbing the land was faster than that of ordinary marches. However, when they heard that there were only more than 120 Japanese cavalry entering Chengde, everyone was immediately angry, and the main force of Tang Yulin's 5th Army Corps withdrew nearly 10,000 people. What kind of foolish war was fought, or it was not fought at all, and a large area of land in Rehe was directly ceded to the Japanese.

Jiang Li, the commander of the 15th Route Army, was only more than 100,000 troops in Mukden at the beginning, but he blocked more than 100,000 Japanese troops from fighting in Mukden for several months. But now more than 100,000 Northeast Army only lost half of Rehe in about half a month, if it were not for the arrival of a cavalry of the 15th Route Army, the entire Rehe would have almost fallen. Tens of thousands of people were driven out of the provincial capital by more than 100 Japanese cavalry. This was not a defeat battle, it was simply a flight from the wind, and without a trace of courage to fight the Japanese army, the great rivers and mountains were ceded to the Japanese army.

"Down with Japanese imperialism!"

"Severely punish Tang Yulin!"

The streets of Beiping and Tianjin were full of students and citizens who were marching and demonstrating. Under the threat of losing their land and losing their country, the tolerance of the population to flee without a fight is minimal. At the same time, the 15th Route Army in Chengde was just like Yu Fengtian at the beginning, which attracted the attention of tens of thousands of compatriots across the country.

"Fuck, where is this war." After the Gubei Pass. Zhuang Huchen looked at the routs who fled all the way south. Let the soldier stop the car. Jumping down from the bumpy car, he greeted the deputy regiment commander Li Jiandao, "Brother Zihua, the 4th and 5th armies have been defeated, and the main forces of the Eastern Economic Army have also withdrawn to the front line of the Great Wall one after another. I must immediately lead my troops to help, but even if all my regiment is on board, I am afraid that it will not help, and there will be reinforcements behind, and the main force of the military seat will not be able to catch up for a while. I'll give you a company, as long as there is a rout, whether he is from the 4th Army Corps or the 5th Army Corps, stop it first and forcibly absorb it, as long as there is resistance. Kill on the spot. ”

"Don't worry, I'll be stubborn. I also have to send out a whole reinforcement army. Li Jian nodded murderously.

Without further ado, leaving a company for Li Jian, Zhuang Huchen rushed to Chengde with the main force of the regiment, and it was not far from Chengde after leaving Gubeikou, and he hurried all the way to Chengde, and finally arrived in Chengde before the Japanese army.

The cavalry regiment was not good at defending the city, and after the main force of Zhuang Huchen's regiment arrived in Chengde, Shao Jianbing led the cavalry regiment to leave the city and march northward in the direction of the Japanese army, bringing some sappers and mines to delay the advance of the Japanese army as much as possible.

"It's back, it's back!" As the air buzzed, a cramped plane flew back onto the lawn, and the United States was weak in Canada to the north and Mexico to the south, and the continental United States was the safest region in the world. In addition to the military's military aircraft, there are also civil aircraft and experimental aircraft of some airlines. At this time, the United States was not strict about air control, and there were grasslands and farms as far as the eye could see beneath the planes. It's a big land. Xu Shiying, who flew the plane, was supposed to train pilots in Lanzhou, or go to Nanyuan and Tangshan airports to direct operations. However, the United States sent people back to Lanzhou, saying that the prototype aircraft was about to be launched, so Xu Shiying took two assistants and rushed to the aircraft factory founded by Wang Xiaofeng and others non-stop.

Sitting on the plane and shuttling back and forth in the air, Xu Shiying had to sigh at the richness of the land in the United States, compared to the undulating Republic of China, there is no war, and there are fewer natural disasters, this side is more suitable for farming and living, but no matter how good it is in a foreign land, it is not a place to live for a long time, with such feelings, Xu Shiying drove the plane to land on the airport, and after sliding on the runway for a distance, some ground crews rushed over to check the body and take him off the ground.

"How does it feel?" Zhu Jiaren first greeted him and asked.

"The body vibration is clear when taking off and landing, and the engine is a little weird when turning to the left." Xu Shiying is an extremely experienced pilot, otherwise he would not have been sent to the United States, but after only one or two test flights, he picked out the faults of the prototype aircraft trial-produced by the aircraft factory.

"Of course, on the whole, this aircraft is still quite good, the speed is more than 40 kilometers per hour higher than the Italian Ca30, and the firepower and comfort are also quite satisfactory." AFTER TALKING ABOUT THE SHORTCOMINGS OF THIS KIND OF AIRCRAFT, XU SHIYING SMILED AGAIN, ZHU JIAREN AND WANG XIAOFENG ARE ALL GRADUATES OF THE MASSACHUSETTS INSTITUTE OF TECHNOLOGY, AND THEY NATURALLY INHERIT SOME OF THE IDEAS OF THE UNITED STATES IN THE DESIGN OF THE AIRCRAFT, AND THE COMFORT OF THE CAB IS MORE STRINGENT THAN THAT OF ITALIA, AND THE FIREPOWER OF TWO 12.7MM AND TWO 7.9MM MACHINE GUNS CAN BE REGARDED AS OUTSTANDING IN THE WORLD'S FIGHTER GROUP.

"Well, this is the M31 engine that Ford commissioned to design, and there are still some imperfections, but Ford's designers refused to make any other improvements to it, so we bought the production license of the engine, and we had to solve the improvement work ourselves. In addition, Europe is looking for a new engine to replace the M31 engine. However, as long as this fighter is capable of the current combat mission, I am afraid that after the initial testing and improvement, production will also start in advance. After listening to Xu Shiying's words, Zhu Jiaren said.

"Yes, the Japanese army is attacking Rehe on a large scale, and the commander has almost sent out the essence of the newly formed air force this time, but unfortunately this newly produced Eagle fighter is afraid that it will not be able to catch up with this war." Xu Shiying sighed, now it is just the production of the first prototype machine, and it will take a few more tests to make some improvements before continuing to produce the second and third prototype machines. No matter how fast it is, it will take a month or two. After finalizing the mass production of the model, the output will not be very high at the beginning, and we can only hope that after the Battle of Rehe, the Eagle fighters produced here can supplement Gao Zhihang's combat consumption in time.

"By the way, why didn't Professor Wang and Professor Zeng come?" Xu Shiying asked again.

"They are now tackling the key technology of the bomber, and they will not easily go away, and the commander has to add more than just fighters." Zhu Jiaren said that the B10 bomber that appeared at last year's air show came from Martin, and this new bomber is more than 1.5 times faster than all the bombers in service in the world today. Even some fighters are not as fast as the B10, and the Fokker D16, which has begun to be reorganized into the Northwest Air Force, is only slightly faster than the B10. As Jiang Li said when leaving Lanzhou, the era of high-speed, heavy-duty bombers is coming.

It turns out that the bomber design presided over by Zeng Yijing and Wang Xiaofeng has undoubtedly become an outdated product, which shows that their work on the American side is not smooth sailing. It is this Eagle prototype machine, which was also made after disassembling the Ca30 and absorbing a certain amount of experience from the other party. However, this can also show that although the overall aviation industry of the Republic of China is far behind the great powers, Zhu Jiaren and Wang Xiaofeng, who graduated from the American Institute of Technology, are not inferior to foreign senior designers.
