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 whole of the army is lifeless, and all units of the army are also busy reorganizing, to be precise, the units that were previously disabled are being reduced or withdrawn, such as the famous "Angang Detachment," which was swept away by the Siberian garrison on 10 September.

It is said that the army aviation unit is relatively better, at least it can tear down the east wall and make up the west wall, and transfer experienced troops from the mainland and the Pacific theater, but it is said that the factories in China are not able to send enough fighters to the front line in a timely manner like China, and as a result, some antique planes have to frequently "talk about the old man and make a teenager crazy" and fight for his life and engage in "life and death" with Chinese fighters in the sky over the Sangye River. In mid-September, the army aviation in Eastern Siberia was exhausted by the Chinese planes that covered the sky, and fighting a war of attrition with the Chinese is generally a tragic end. The Army Aviation Headquarters had to transfer one flying regiment each from the Pacific front, which was also under fire, to supplement the 2nd Flying Regiment 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 people, and seeing that the 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." Beginning in late September, China's "Kuaidao" bombers brought their own "gifts" every day and went to the airspace above the defense line and support points of the Japanese army on time and on time, and returned to the Syrian army, which had left behind bomb craters and had been blown up to ashes. At the beginning, the "swiftlets" and "woolly rhinos" were still in ambush at high altitude waiting for the "Kuaidao" fighters to come and drive away the "Kuaidao" group, and after a few days of fighting, they found that the army aviation had made turtles with shrunken heads, so they simply dived down and made a cameo appearance in the ground attack mission, forcing the army position to have to add a bunch of bullets and shells every day.

Although they were covered in bruises, they still desperately sent bomber squadrons to pay tribute to the Chinese Air Force with bombs. Just here, between you and me, skirmishes between Chinese fighters are even more frequent. In mid-September, after the elite of the army air force was completely lost, Chinese fighters grew up in the blood of both sides. The ratio of victory and defeat between China and China has been completely reversed, and it is said that for every Chinese fighter shot down, it will have to pay the price of three of its own fighters. On 21 September, a new round of large-scale air battles broke out over Mount Baanda. The battle was caused by an attempt by the Yue army on the east bank of the river to cross the Sangye River again. The army concentrated almost all of its artillery units, and also raised artillery observation balloons. The Northeast Army discovered the army's attempt, and a "swiftlet" fighter single-handedly shot down the observation balloon with an ultra-low-altitude surprise attack that the army recalled "just a few meters above the ground." The embarrassed and angry army sent dozens of fighters to support, plus the light and heavy critique planes originally scheduled to support the ground attack, the army sent about 120 fighters, about half of which were "Gale" fighters. The wealthy Chinese Air Force was beaten by the surprise attack of the Yue army and retreated for a while, and after relieving itself, 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 army withdrew to its starting position in disgrace, leaving behind the corpses and wreckage of the ground, and lost the last ounce of courage to cross the river by surprise. After that, the army did not dare to launch a river crossing operation. The ground operation was deflated, but the army air force in the sky once again made a big statement, reporting the number of downed planes as high as 89 planes, while the Chinese side was relatively honest and only reported the results of 42 planes. In fact, after the war, the Northeast Army lost 5 "swiftlets", 2 of which were shot down by the anti-aircraft artillery units of the Japanese army on the ground. The losses on this side were extremely heavy, and about 24 "Gale" were shot down, which also shows from the side that the shooting skills of the newly replenished pilots of the Chinese army are very problematic. In the early morning of September 25, the "Wind" balloon was once again released 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 China and the Yueben soldiers. Therefore, the Chinese Air Force once again sent a three-plane formation of "Golden Swiftlets" to launch an ultra-low-altitude surprise attack, and although he himself weaved a dense network of fire, he could only helplessly watch as the Chinese fighter jets turned the observation balloon into a fireball in full view of everyone.

Because the army aviation was unable to provide enough new "Gale" fighters, some of the "Zero" fighters that had been replaced had no choice but to rush onto 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 warriors 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 oolong ball was created by me 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 been dismantled into eight pieces, back to Yanjing for a comprehensive test.

Kashima Cao Naga belonged to the 1st Flying Squadron of the 11th Flying Squadron, and according to the recollection of Koichi Iwase, an ace pilot of the Japanese army, he shot down a Chinese fighter plane during the melee that day, and then he found that the lone Kashima Guncho followed him to his wingman position in a daze. Before Iwase, Yoshiyama Fumiji had already taken Kashima for a while, but it is not known whether Kashima's fighter plane was too badly injured or if he himself had a nervous breakdown, and the efforts of Iwase and Yoshiyama were ultimately ineffective. 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 and tried to rescue him, but was beaten into a pile of flames by a Northeast Army tank that rushed at full speed. Seeing that Aoyagi was injured, Iwase Yukichi dived down without hesitation, and with superb piloting skills, he steadily stopped behind the Kashima fighter, and as a result, Kashima and Aoyagi, who was seriously injured, both squeezed into the narrow cockpit of the "Gale" fighter, and took off and escaped in the rain of bullets and bullets of the pursuing Northeast Army. Iwase's heroic actions made him famous, and he was awarded a certificate of appreciation from the commander of the 2nd Flying Regiment himself.

As the battle progressed, the tactics of the Chinese side became more and more deceitful. On 29 September, "Flying General" Bao Yunsheng demonstrated his famous tactics in Spain: 20 "woolly rhinos" stepped on the morning light to kill the airfield of the front line of the Syrian army on Alan Mountain. What is surprising is that the fighters of the Northeast Army even circled in the sky over the Yuejun airfield, patiently waiting for the 11 "Zero" fighters to rush onto the runway and try to take off urgently to meet them, the "woolly rhinoceros" suddenly swooped down, and the ferocious machine-gun fire swept across the entire runway in an instant. The "Zero" fighters, which had already begun to slide, had nothing to hide, and were swept away by a rain of bullets, and two "Zero" fighters exploded on the spot, burning the entire runway into a sea of fire. The other nine planes crashed into the tarmac near the runway, causing more damage. The entire Alan Mountain Airport was disturbed by the Northeast Army's attack. To my surprise, it is not so simple for the Chinese to flood 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 officers and men of the Alan Mountain Airport were about to release the fighters, and the ground crew was about to rest, when the second batch of Northeast Army fighters flew in again. On 2 October, the fighters of the Northeast Army again visited the Yuejun airfield near Jinguangsi, and a few rounds later, the Jinguangsi airfield was covered with smoky wreckage and the tired local service personnel, 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 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 wind was raging and the grass and trees were all soldiers, and there were many cases in which troops concentrated all their firepower to engage in "fireworks displays" for no reason. What is even worse is that the flying Chinese planes bullied the army air force 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 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 cut 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 army in different ways, Yanjing 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 China National Institute of Fluid Power, they did not know that the flying "swiftlets" already possessed a terrifying 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 Tiger" rocket was stabilized by turbojet spin, but it was found that the density of multiple bursts was far from the design requirements during the aerial firing experiment, and 28% to 30% of the charge column would be consumed on the rotation of the rocket by adopting the turbojet method, so the National Institute of Fluid Power of China chose to use the method of using a projectile 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".

During 1935, the "Ten Thousand Tigers" rocket was test-launched many times, accumulating a large amount of data and valuable experience. Before 1936, the "Ten Thousand Tigers" rocket used a U-shaped cassette launcher, but in the test flight, it was found that this kind of launcher would produce terrifying air resistance and wing turbulence, which would not only affect the speed of the fighter, but even threaten its ability to control the fighter. In 1937, China's National Academy of Rocket Science developed a T-slot guide-rail launcher codenamed "Orchestra", and the launch frame of the "Wanhu" rocket adopted an "N" type. The launcher used by the "Wanhu" rocket mounted on the "swiftlet" was not the same as that used by the later "Hongyan" gunboat, with a total length of 1,000 mm, a long tail of 825 mm guide rails, and four guide rails on each side. On 16 November, the "Swiftlet" fighters carrying the "Ten Thousand Tigers" finally showed their skills four days later, at 5 p.m. on 20 November. At that time, under the command of Captain Ye Ning, these "swiftlets" carried out the task of covering the bombers, and after discovering the group of interceptors of the Yue Army, according to the order of Captain Ye Ning, five planes unexpectedly launched a salvo at a distance of 1,000 meters, shooting down two Yue Ben 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 "swiftlets" in the entire Sangye River Campaign, and they were unscathed. It should be said that the Chinese's war results were all achieved under extremely favorable conditions; because the Northeast Army did not know in advance that it had weapons with an effective range of more than 800 meters, the group of interceptors discharged a dense formation moving horizontally at a uniform speed, and the Chinese described launching a rocket attack on the formation of enemy planes 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 Yue himself, and many people even began to worry that the Chinese would launch a large-scale terrorist night attack on the mainland.

Just when the front-line army was helpless to be harassed by the Northeast Army, on 19 November, a large number of "Kuaidao" bombers suddenly touched the sky above the Sukhara Mountain Railway Station and blew up this pivot button for the supply of the army on the Sangye River front 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 defense line of the army 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 trees wanted to be quiet but the wind did not stop, and the surviving Yue soldiers listened to the explosion outside and quieted down, and were about to celebrate to save their lives again, 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 the Last Judgment sweeping across the entire defense line.

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

The explanation given by the army aviation was that they had been transferred inland by the Siberian garrison, and that they could not be whipped. Of course, the more important reason is that the army aviation unit has been terrified by the Chinese Air Force at this time, and the so-called transfer to the inland is just a reason for this group of cowards to explain that there has never been a single fighter plane to launch a counterattack against the huge Northeast Army aircraft group.

However, the psychology of the army aviation is also clear, and it can be said that the first time it can be said that the rescue is too late, and the second time it can only bite the bullet. As a result, a few hours later, the Chinese Air Force gave the army aviation a chance to prove its mettle. The cunning Chinese Air Force this time discharged a position of "luring the enemy," 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 high altitude behind the bomber group, ready at any time to outflank the planes that came to send them to death.
