The ground troops were frantically sharpening their knives in the camp, and in addition to the routine patrols of the planes on both sides every day, they did not have the leisure to come out in groups to pick quarrels and provoke troubles to compete, and they were busy greeting the "guests" at the front-line airfields. On the Chinese side, two fully manned new air regiments arrived at the front line, and at the same time, the 70th Fighter Regiment and the 150th High-Speed Bomber Regiment also received the long-awaited new "Swiftlet" fighters and "Woolly Rhinoceros" heavy fighters. For example, when the 70th Air Regiment was counting its belongings, it found that it had now become a landlord with more than 100 fighters. Compared with the rapid progress of China's Northeast Army from the troops to the whole individual, the Japanese side seems to be lifeless, and the Japanese army is also busy reorganizing, to be precise, the previously disabled units are being reduced or withdrawn, such as the famous "Yasuoka Detachment", which was swept away by the Siberian garrison on September 10.

The Japanese army aviation is relatively better, at least it can tear down the east wall and make up for the west wall, and transfer experienced troops from the mainland and the Pacific theater, but Japan's domestic factories cannot send enough fighters to the front line in a timely manner like China. In mid-September, the Japanese army aviation in Eastern Siberia was exhausted by the Chinese planes that covered the sky, and fighting a war of attrition with the Chinese was generally a tragic end. The Japanese Army Aviation Headquarters had to transfer one flying regiment each from the Pacific front, which was also under fire, to supplement the 2nd Flying Corps in Eastern Siberia, barely maintaining its combat strength at the level of 200 aircraft. Of course, the Chinese have always been the masters of unforgiving, and seeing that the Japanese army aviation on the other side of the river was dying, the Northeast Army immediately decided to "take advantage of your illness to kill you." Starts in late September. China's "Kuaidao" bombers brought their own "gifts" every day and went to the skies above the Japanese defense line and support points on time and on time. Returning to the Japanese army, which was left with a bomb crater and a bombed face. When it started. The "swiftlets" and "woolly rhinos" were still setting up ambushes at high altitude and waiting for the Japanese fighters to come and drive away the "Kuaidao" group, and after a few days of fighting, they found that the Japanese army aviation had made turtles with shrunken heads, and they simply dived down themselves to make cameo appearances in the ground attack mission, forcing the Japanese positions to have to add a bunch of bullets and shells to their meals every day.

The Japanese Army Aviation is also not vegetarian. Although he was covered in bruises, he still desperately sent a bomber team to pay tribute to the Chinese Air Force with bombs. Right here, you come and go. Skirmishes between Chinese and Japanese fighters were even more frequent. Although the Japanese army aviation was at the end of its strength, after the elite of the Japanese army aviation was completely lost in mid-September. China's fighter planes, however, have grown up in the blood of both sides. The win-loss ratio on the Chinese and Japanese sides has been completely reversed. For every Chinese fighter shot down by the Japanese side, it had to pay the price of three of its own fighters. On 21 September, a new round of major air battles broke out over Mount Baanda. The battle was caused by an attempt by Japanese troops on the east bank of the river to cross the Sangye River again. The Japanese concentrated almost all of their artillery units, and also raised artillery observation balloons. The Northeast Army discovered the Japanese army's attempt, and a "swiftlet" fighter single-handedly shot down the observation balloon with an ultra-low-altitude surprise attack that the Japanese army recalled "only a few meters above the ground." The Japanese army, which was embarrassed and angry, sent dozens of fighters to support. In addition to the Japanese light and heavy attack planes originally intended to support the ground offensive, the Japanese army sent about 120 fighters. About half of them were Gale fighters. The wealthy Chinese Air Force was defeated by a surprise attack by the Japanese and retreated for a time, and after relieving himself, Zhong Liwei immediately launched an unstoppable counterattack with hundreds of tanks and armored vehicles. While China's steel behemoth dominated the battlefield, flying Chinese planes also obscured the sky again, and the Chinese Air Force sent a huge formation of 157 fighters, including a total of 95 swiftlets and 62 woolly rhinos. After several hours of melee in the open field, at 4 p.m., the Japanese troops retreated to their starting positions in disgrace, leaving behind corpses and wreckage, and lost the last shred of courage to cross the river by surprise. After that, the Japanese army did not dare to launch a river crossing operation. The ground operations were deflated, but the Japanese army aviation in the sky once again let out a big statement, reporting the number of downed planes as high as 89 planes, while the Chinese side was relatively honest, only reporting the results of 42 planes. In fact, after the war, the Northeast Army lost 5 "swiftlets", 2 of which were shot down by the Japanese anti-aircraft artillery units on the ground. The losses on the Japanese side were extremely heavy, with about 24 "Gale" shot down, which also showed that the shooting skills of the newly replenished pilots of the Japanese army were very problematic. In the early morning of 25 September, the Japanese side once again released the "Wind" balloon as an artillery observation platform, and the enemy's "repeated teachings" completely angered Zhong Liwei, who ordered that no matter what the price was, the balloon must be reimbursed in front of the Chinese and Japanese soldiers. As a result, the Chinese Air Force once again sent a three-plane formation of "Golden Swiftlets" to launch an ultra-low-altitude surprise attack, and although the Japanese weaved a dense network of fire, they could only helplessly watch as the Chinese fighter jets turned the observation balloon into a fireball in full view of everyone. …,

Because the Japanese army air force was unable to provide enough new "Gale" fighters, some of the "Zero" fighters that had been replaced had to rush to the battlefield, and suffered greatly because of the problem of poor protection.

While the Siberian garrison on the ground completely lost the courage and will to attack, the Japanese samurai in the sky still held on. In the week after September 21, a bloody storm blew over the Sangye River, and more than 100 large-scale chases, dog fights, and scuffles were staged every day. The most classic and far-reaching own goal was made by the Japanese on September 25, 1942. On this day, Kashima Shintaro Cao Chang was injured in the landline after a bloody dog fight, and was forced to make an emergency landing. As a result, China unceremoniously accepted this great gift from the sky -- it took only two days for the Northeast Army to transport the "Gale," which had already been dismantled into eight pieces, back to Beijing for a comprehensive test.

Kashima was part of the 11th Flying Squadron of the 1st Flying Squadron, and according to the Japanese ace pilot Koichi Iwase, he shot down a Chinese fighter during the day's scuffle, and then he found that the lone Kashima Commander Cao was dizzy and followed his wingman. Before Iwase. Fangshan Bunji Cao Chang had already taken Kashima Cao Chang for a while, but he didn't know that Kashima's fighter plane was too badly damaged. Or did he himself have a nervous breakdown. The efforts of Iwase and Yoshiyama ultimately failed. Under Iwase's anxious gaze, Kashima Caocho staggered to land in the Chinese-controlled zone. Fortunately, not everyone was stunned, and Aoyagi Guncao ventured to land beside Kashima in an attempt to rescue him. But it was beaten into a pile of flames by a Northeast Army tank that rushed at full speed. Seeing that Aoyagi was injured, Yukiichi Iwase swooped down without hesitation. With superb piloting skills, he stopped steadily behind the Kashima fighter, and as a result, both Kashima and Aoyagi, who was seriously injured, squeezed into the narrow cockpit of the "Gale" fighter. In the hail of bullets and bullets of the pursuing Northeast Army, he took off and escaped. Iwase's heroic actions made him famous. As a result, he received a certificate of appreciation from the commander of the 2nd Flying Corps.

As the battle progressed, the tactics of the Chinese side became more and more deceitful. On September 29, "Flying General" Bao Yunsheng demonstrated his famous tactics in Spain: 20 "woolly rhinos" stepped on the morning light to kill the Japanese front-line airfield at Alan Mountain. What was surprising was that the fighters of the Northeast Army even circled over the Japanese airfield, patiently waiting for the 11 "Zero" fighters to rush onto the runway and try to take off urgently to meet them, and the "woolly rhinoceros" suddenly swooped down. Ferocious machine-gun fire swept across the runway in an instant. The Japanese "Zero" fighters, which had already begun to slide, had nothing to hide, and were swept away by the rain of bullets. Two Zero fighters exploded on the spot, burning the entire runway into flames. The other nine Japanese planes crashed into the tarmac and other places near the runway, causing more damage. The entire Alan Mountain Airport was disturbed by the Northeast Army's attack. To the surprise of the Japanese, it is not so simple for the Chinese to flood with bad water. Almost two hours later, the airfield group of the 2nd Flying Corps finally cleared the runway of the Alan Mountain Airport, and the busy sweaty Japanese officers and men were about to release the fighters, and the ground crews were about to rest, when the second batch of Northeast Army fighters flew in again. On 2 October, the fighters of the Northeast Army came to the Japanese airfield near Jinguangsi again, and after a few rounds, the Jinguangsi airfield was full of smoky wreckage of Japanese planes and tired Japanese ground crews, and they completely lost their combat capability. In mid-October, there are more "nocturnal strangers" in the silent night sky of the Mulberry River. They approached silently, dropped a few bombs and flew away, these are the "Crow" night fighters newly equipped by the Chinese Air Force. They quickly became the dream killers of the Siberian garrison. At this time, the Japanese troops, who were long in night raids, were also tortured to the point of mental collapse, and many troops were frightened overnight, almost to the point where the rumors were all in the air, and there were many cases in which troops concentrated all their firepower to engage in "fireworks displays" for no reason. What was even worse was that the flying Chinese planes bullied the Japanese army aviation for lacking the ability to intercept at night, and even took out the "Kuaidao" bombers to carry out night raid missions. As a result, the Japanese officers and men on the ground listened to the huge engine noise of the "Kuaidao" bomber slowly approaching, and then it was the baptism of bombs that split their heads and covered their faces, but they were powerless and had nowhere to escape, and the morale of the whole army was extremely low. …,

Just when the Chinese Air Force was ravaging the Japanese army in different ways, Beijing sent new weapons. In November, the official production version of the "Golden Swiftlet" appeared in a group over the Sangye River with a powerful "Taihang" engine, a 23-mm cannon and six 12.7-mm aviation machine guns. When five "swiftlets" arrived at the Sangye River on 16 November with this classic weapon that had been changed several times by the National Institute of Fluid Power, Japan did not know that the flying "swiftlets" already possessed a terrible weapon that frightened them.

The "Ten Thousand Tigers" 75-mm rocket is an epoch-making weapon. At that time, the diameter of the rocket engine column of the Chinese experiment was 10 mm, and 7 and 10 mm columns were loaded into the cylindrical combustion chamber, and the diameter of the combustion chamber was 70 mm, plus the wall thickness of the combustion chamber was 5 mm, and the caliber of 75 mm was produced, and the choice of 125 mm caliber was also for the same way. The original 75-mm "Ten Thousand Tigers" rocket was stabilized by turbojet spin, which was discovered during an aerial firing experiment. The density of multiple bursts is far from the design requirements, and it adopts the turbojet method. Between 28% and 30% of the column is spent on the rotation of the rocket. Therefore, the National Institute of Fluid Power of China chose to use the method of using a bullet wing with an annular stabilizer. In terms of wingspan selection, wind dynamics and actual design experiments were carried out on the wings of various wingspans, and finally a wingspan of 150 mm was selected on the "Wanhu".

In 1935, the "Ten Thousand Tigers" rocket was test-fired several times. Accumulated a large amount of data and valuable experience. Before 1936, the "Ten Thousand Tigers" rocket used a U-shaped cassette launcher, but it was found that this type of launcher would produce terrifying air resistance and wing turbulence during test flights. Not only will it affect the speed of the fighter, but it will even threaten its handling performance. In 1937, China's National Academy of Rocket Science developed a T-slot guideway launcher codenamed "Orchestra". The launch frame of the "Ten Thousand Tiger" rocket is of the "N" type. The launcher used by the "Ten Thousand Tigers" rocket mounted on the "swiftlet" was not the same as that used by the later "Hongyan" gunboats. Its overall length is 1000 mm, the long tail of the guide rail is 825 mm, and there are four guide rails on each side. The "Swiftlet" fighter plane, which arrived with the "Ten Thousand Tigers" on 16 November, finally showed its skills at 5 p.m. on 20 November, four days later. At that time, under the command of Captain Ye Ning, this group of "swiftlets" carried out the task of covering the bombers, and after discovering the Japanese interceptor group, according to the order of Captain Ye Ning, five planes unexpectedly launched a salvo at a distance of 1,000 meters. Shot down 2 Japanese fighters in one fell swoop. Captain Ye Ning's flight squadron had a total of 34 "swiftlets" equipped with "Ten Thousand Tiger" rockets, and shot down 53 Japanese planes throughout the Mulberry River Campaign**. Unscathed. It should be said that the Chinese's victories were achieved under extremely favorable conditions; because the Japanese side did not know in advance that the Northeast Army had weapons with an effective range of more than 800 meters, the Japanese interceptor group discharged a dense formation moving horizontally at a uniform speed; the Chinese described launching a rocket attack on the enemy aircraft formation in this formation as "smashing a light bulb on the side of the road with stones."

The Chinese's night raid tactics caused serious psychological trauma to the Japanese, and many people even began to worry about the Chinese launching a large-scale terrorist night attack on the Japanese mainland.

Just when the Japanese army on the front line was helpless to be harassed by the Northeast Army, on November 19, a large number of "Kuaidao" bombers suddenly touched the sky above the Sukhara Mountain Railway Station, and blew up this hub button for the supply of Japanese troops on the Sangye River front line into a sea of fire. The thunderous Siberian garrison pulled a large number of fighters back to the heart of Eastern Siberia, preparing to resist the Northeast Army to launch a similar long-range interdiction operation again. At dawn on November 20, the heavy artillery group of the Northeast Army hidden on the high ground on the west bank of the Sangye River was shocked, and all the air defense headquarters and strong support points on the Japanese defense line were baptized by the rain of steel bullets, and most of them went to hell. The "swiftlets" and "woolly rhinos" also swooped down on the storm blowing by the bombers, and "named" the surviving Japanese troops who were lucky enough to escape the rain of fire one by one. The surviving Japanese soldiers listened to the sound of explosions outside and were about to celebrate the death of the Chinese plane when the wings of the Chinese plane once again obscured the sky. Amid the deafening roar of engines, 344 fighters covered 260 "Quick Knife" bombers, like the scythe of death of Doomsday sweeping across the entire Japanese defense line.

Before being blown to pieces, many Japanese officers and soldiers were angry looking forward to the arrival of Japanese fighters in the sky, "Where did the Japanese army aviation die?" And the female relatives of the Japanese pilots became the most common greetings of the officers and soldiers of the "Imperial Army" on the Sangye River that day.

The explanation of the Japanese army aviation was that they were transferred inland by the Siberian garrison, and they were beyond the reach of the whip. Of course, the more important reason was that the Japanese Army Aviation had been terrified by the Chinese Air Force at this time, and the so-called transfer to the inland was just a reason for this group of cowards to explain that not a single Japanese fighter had ever launched a counterattack against the huge Northeast Army aircraft group.

However, the Japanese army aviation is also psychologically clear, and it can be said that the first time it can be said that the rescue will not be possible, and the second time it can only be hard-headed. As a result, a few hours later, the Chinese Air Force gave the Japanese army aviation a chance to prove its mettle. The cunning Chinese Air Force this time discharged a "luring enemy" formation, starting with 52 "Kuaidao" bombers, escorting less than 60 fighters, and more than 100 of the latest "swiftlets" and "woolly rhinos" lying in ambush at a high altitude behind the bomber group, ready at any time to outflank the Japanese planes that came to send them to death.
