After arranging the things to welcome and entertain Mr. Chen and his entourage, Yang Tianfeng plunged into aviation manufacturing again, making every effort to carry out the transformation of aircraft, training in air combat, and training of personnel.

Although the strategy of replacing the attack with siege implemented by the devils did not make the base area face a greater threat, there were still some deployments during the siege, which made Yang Tianfeng realize that another war would soon be launched in the air.

Jining and Xinxiang are both building airports, deploying aircraft so close to the base area, plus Xuzhou Airport, you can think of the target that the Japanese army will target with your feet.

At that time, the Japanese North China Front Army was attached to the First Flying Regiment, with 36 heavy bombers and 27 reconnaissance planes; Twelve fighters, eighteen light bombers. It seems like a lot of them, but they are not the most advanced and best fighters.

Of course, it was more than enough to use these planes to bully the anti-Japanese forces behind enemy lines, and there were very few battle losses. However, in the battle with the New Seventh Army, the Japanese planes dispatched by the Japanese army in Xuzhou were frustrated several times, so that the Japanese army could not figure out whether it was the base area's own planes or from Xinyang and other airfields to help in the war. Therefore, they did not dare to act rashly, they were scouting, investigating, and preparing for revenge.

The strategy adopted by Yang Tianfeng was to be forbearing, ignoring the tentative and probing attacks of the Japanese reconnaissance planes for the time being. The result of this is to buy time for development and to make the counterattack sudden and sharp. However, as the Japanese army becomes more and more emboldened, it is likely that they will launch air strikes on the base areas in order to destroy the military industry and other industries in the base areas and to undermine the morale of the soldiers and civilians in the base areas.

Sooner or later, the air battle will take place, and Yang Tianfeng is just waiting for the "air force" to become stronger and more favorable for the operation.

A network of ground air defense posts has been established, air raid shelters are becoming a common means of evasion for the common people, and the commissioning of the radar has been completed and the work of operation has begun. The maturity of these conditions has increased Yang Tianfeng's confidence, and he realizes that the time is becoming more and more ripe for air combat.

At present, the manufacture and assembly of the second radar is underway, the modification of the aircraft is also progressing smoothly, and another group of pilots of the national army have come to the base area to conduct adaptive flight training for the new aircraft.

The modification of the aircraft went more smoothly than originally estimated, reaching six aircraft a month. Because, many lines and parts on the original aircraft can be utilized, which greatly shortens the time of modification. And with the increase of workers, the technology is proficient, and the efficiency can continue to improve.

The development of the mechanical two-stage two-speed supercharger is nearing completion, and the performance of the aircraft will be improved. Even the current flight performance has been greatly appreciated by the pilots who flew over it.

And how to make full and effective use of these pilots before they finish their training and fly back to the rear to hit the devils is something that Yang Tianfeng is thinking about hard. Because air combat must be carried out in the base area, even if the plane is damaged in battle, the pilot has a great chance to escape.

Based on such considerations, we cannot passively wait for the devils to repair the airport and deploy the plane. Yang Tianfeng wanted to hold the initiative in his hands, lure the devil's plane into the base area, and then use the radar detection to launch a prepared attack.

And the devil does not have a radar, this is a fighter that can be used. Raid the airport at night and bomb several of its planes in order to provoke the devils and lure them to take off from farther airports to bomb the base areas.

When it comes to night flight, it's a performance that even devils' planes don't have. However, under Yang Tianfeng's planning and preparations, the "air force" in the base area is undergoing urgent training to master this skill.

In the early days, long-range flights relied mainly on the compass, and once the course was correct, the time to reach the target could be predicted based on the airspeed of the aircraft and the approximate wind speed. If the weather is nice, you can navigate under the stars, but most of the time, all the pilot can do is pray!

While the pioneers of flight challenged nature with their fearless spirit, scientists and engineers struggled in another field. As early as 1911, the directivity of radio waves was studied. In World War I, primitive ground-based radio direction-finding navigation was used when German zeppelins bombed London.

What Yang Tianfeng uses is a navigation system that integrates technology that is no longer a precedent, supplemented by radar detection and positioning, and corrects deviations.

The first was the construction of two radio towers in close proximity to the airport, emitting phase-complementary Morse codes. If these two codes are used with a dot transverse system, when the aircraft is on the left side of the beam centerline, the pilot hears the dot when it is on the right side, and when it is in the center, it hears an uninterrupted signal due to the simultaneous reception of two signals.

This directional direction finding method is a blind landing system invented by the German company Lorenz, which is characterized by the fact that the on-board equipment is very simple, just a normal radio receiver. And its disadvantage is that the emitted radio beam is unidirectional, and there is no orientation ability for other directions in 360 degrees. Therefore, it can only be used for guided landing and very special bombing guidance, and cannot be used for ordinary aviation navigation.

However, with radar and radios on the plane, it gives the plane an extra layer of support for night flight. With detection and positioning, the radar station can correct the course of the aircraft with radio. Moreover, what Yang Tianfeng asked for was a very special bombing guidance, and the target was set at the devil's Xuzhou Airport.

Up to now, only Xuzhou Airport has a relatively large number of devil planes, and it has constantly dispatched to carry out exploratory and gradually in-depth reconnaissance of the base area. Therefore, Yang Tianfeng set the direction of Xuzhou Airport through radar and locked the direction of the beam emitted by the radio transmission tower.

At the same time, first at dusk and then at night, Yang Tianfeng drew up a step-by-step night training plan for the "Air Force," and began intense training with a bomber formation composed of reconnaissance planes, biplanes, and ultra-light gray planes.

Moreover, according to the detection of radar, Yang Tianfeng also dispatched reconnaissance planes on many occasions to conduct road exploration surveys in the absence of devil planes in the air, familiarize himself with the terrain and landforms, and landmark buildings, draw up route maps, and set up ground guidance signs in the base area.

In addition, Yang Tianfeng also led military technicians to step up the production of bombs for bombing. If it's too heavy or too big, the plane will definitely not be able to carry it, so don't think about any anti-runway bombs. However, in view of the weakness of air defense caused by the arrogance of the Japanese devils, throwing them at an altitude of more than 1,000 meters can not only ensure the safety of the aircraft as much as possible, but also cause as much damage as possible, so it is necessary to win by quantity.

How fragile the plane is, a shuttle bullet, a grenade, can reimburse it. Therefore, according to the carrying capacity of his own aircraft, Yang Tianfeng mainly produced a batch of small explosive incendiary bombs with time-delay fuzes. The big ones are only three kilograms, and the small ones are only one kilogram, so what you want is dense.

As for the size of the results, Yang Tianfeng actually didn't have much extravagance, mainly to lure the devils to retaliate and strive to fight an air battle in the base area. And it's best to do it before July, before Zero Egg arrives in China.

Of course, the time should not be too early, and the time before the Battle of the Hundred Regiments should be shortened, so as to prevent the devils from concentrating their forces in the Shandong-Henan-Anhui border area too early. Therefore, he tentatively set the time for the air raid in mid-to-late June, and made more adequate preparations in the next two months or so.

Yang Tianfeng is very busy, military, military industry, government affairs, etc., although not every work has to be done personally, but guiding, reviewing, listening to reports, etc. also take up most of his time.

It was also at this time that a group of Nanyang overseas Chinese condolence groups took a plane from Chongqing to Luoyang, and after a short visit and inspection, they came to Zhengzhou, and then crossed the Yellow River and entered the Shanxi-Henan-Anhui border area.

Historically, in the most difficult days of the War of Resistance Against Japanese Aggression, in addition to the people in China, there was also a pillar that supported the great cause of the Chinese people's War of Resistance in spirit and economy -- that is, more than 8 million overseas Chinese.

Overseas Chinese form three major groups in the region: the first group, Nanyang overseas Chinese. The number of people living in Nanyang countries is more than 6.7 million, and the Nanqiao Association was established under the leadership of Tan Kah Kee; The second largest group, the American diaspora. There are mainly more than 100,000 Chinese in the United States, led by Situ Meitang, known as the Hongmen overseas Chinese in the whole of America; The third largest group, the overseas Chinese in Europe, is mainly Chinese living in Britain and France, and has established the All-European Federation of Overseas Chinese to Resist Japanese Aggression and Save the Country.

These Chinese, who live abroad, have accepted the so-called maritime culture, and have been influenced by Western civilization, mostly adopt an impartial and neutral attitude toward domestic partisan disputes, and with the mood of "marrying a daughter," they have devoted themselves to caring for and supporting the "mother's family" in the war of resistance.

They believe that it is because of the feudal autocratic rule of the past dynasties in China that the people have been fooled, and the ignorance of the people and the backwardness of science and culture have resulted in the shameful reality that the big countries are bullied by the small countries and the big countries are beaten by the small countries. They fantasize that the heads of the Chinese can be "enlightened" under the fierce bombardment of foreign aircraft and artillery—abandoning the feudal autocracy that severely restricts the hands and feet and wisdom of the nation, and truly accepting civilization and science.

Therefore, this part of the Chinese tighten their belts to support the war of resistance than the people in the rear of the country to support the war of resistance, and there is one additional condition, that is, the national government that accepts their economic support must ensure domestic political democracy and freedom. Therefore, as soon as disputes and frictions between domestic political blocs broke out, the overseas Chinese always felt bitter, ruthlessly rebuked, and threatened each other with no economic support, and the anti-communist upsurge of the Kuomintang quickly died down, which was directly related to the opposition attitude of the overseas Chinese.

In view of this situation, in the first phase of the War of Resistance Against Japanese Aggression, Chairman Chiang had to temporarily put aside the stinking frame of the Lao Tzu Party and the whole world, and declared that all parties and factions were politically equal, which also created a false impression of democratic politics in China for a time, which was a great comfort to overseas Chinese. They made a clear declaration and spent all their pockets to support the Nationalist Government in the War of Resistance and Chairman Chiang to the end.

In the early days of the Anti-Japanese War, the Nationalist Government established the Wartime Public Debt Solicitation Committee, with Chairman Chiang as the chairman. Overseas Chinese subscribed to most of the 500 million yuan in the first issue of national salvation bonds. From 1937 to 1942, the Nationalist Government issued six national salvation bonds totaling $3 billion. Overseas Chinese bought 1.1 billion yuan, accounting for more than one-third of the total.

Since Chairman Chiang regarded himself as a loyal follower of Mr. Sun ZS and flaunted the banner of democracy and republic, overseas Chinese basically bought his account. Under the Nationalist Government, a special Committee for Overseas Chinese Affairs was established. Through this committee, Chairman Chiang often asked overseas Chinese for help and money. The surprise donations made by overseas Chinese have solved many of the government's problems, but Chairman Chiang was suffering from the perennial war expenditures, so he directly sent telegrams to overseas Chinese organizations in various localities, asking them to make regular monthly donations.

Monthly donation means that there is a fixed amount of donations every month, just like the boss pays wages to workers, every month. Overseas Chinese did their best to pay anti-Japanese donations on a monthly basis, just as they paid their salaries to the Nationalist Government on a monthly basis. The average monthly actual donations of overseas Chinese in Nanyang are: 7.34 million yuan; The average monthly actual donations of overseas Chinese in the United States were: 583,000 yuan: During the eight-year War of Resistance Against Japanese Aggression, the total donations of overseas Chinese amounted to more than 1,322,530,000 yuan.

Overseas Chinese not only contribute money, but also contribute people and efforts. In 1938, the Yunnan-Burma Highway was completed, which became the lifeline of the import and export of the mainland of the motherland during the Anti-Japanese War, and was the main artery of the National War of Resistance Against Japanese Aggression. However, at that time, there was a shortage of experienced truck drivers and auto mechanics in China, and there was no time for temporary training, so the Southwest Transportation Department of the Military Commission, which was in charge of managing the two transportation lines in Kunming, actively recruited mechanics from overseas.

Until May 1942, when the Yunnan-Burma Highway was cut off by the Japanese army, Nanyang mechanics rushed to transport more than 450,000 tons of military supplies, which greatly supported the motherland's anti-Japanese war cause. Among the more than 3,000 mechanics, more than 1,000 sacrificed their lives for the country due to bombings, illness, and car accidents, accounting for more than one-third of all the Nanyang mechanics who returned to China. The heart of an overseas traveler is so hot, so noble and great at a time of national crisis.

“…… To be honest, if it weren't for the strong demand of the state government and a little curiosity about General Yang, who was a traitor first and then a hero, we wouldn't have wanted to go there. At that time, we most wanted to go to the Shaanxi-Gansu-Ningbo Border Region, which is said to be the most progressive place in China. Yet it was fate and God's arrangement, where I met the things and people that changed my life......"

“…… As soon as they arrived in Kaifeng, Zong Hui, deputy director of administrative affairs of the border region, and others came to greet them. The welcome party was relatively simple, but it didn't change our impression. After all, words and deeds in Chongqing can make outsiders understand our preferences. ”

In the evening, Director Zong briefed us on the history of the border area, distributed a booklet, and screened a documentary that was a mix of images and photographs. He also solemnly told us that now and in the future, the land we have walked on has been taken from the hands of the Japanese and recovered, and there is the blood of the martyrs on it, and the heroic souls of the martyrs are reverberated on it. This makes us feel reverence, and perhaps this is also the beginning of a change in our thinking. (To be continued.) Find this site to search for "Biquge CM" or enter the URL:.
