Ogasawara was not carried away by anger, at this time, the entire Kwantung Army had repeatedly suffered heavy losses at the hands of the advance army, and they no longer arrogantly believed that this branch of the army was low in combat and could destroy them at any time, so the necessary war investment was very necessary to find out the enemy's means.

200 planes is not a small force, not to mention Ogasawara Shufu, even the commander of the 'Umezu Mijiro' thinks this plan is feasible, and it will arrive at the target in three directions and at different times, and the Japanese army absolutely believes that even if the other side has the means to intercept it, it will not be able to build Harbin into an iron bucket.

As for why Harbin was bombed, the reason is too simple, the ally Lao Xi transported a large number of lathes, as well as the steel pipes they produced, which must be destroyed, otherwise, the enemy will have a chance to grow.

So, with the order of Ogasawara Shuo, the airport in Shinkyo roared, and one plane after another soared into the sky, gathered in a slight circle, and flew towards the twin cities with a roar.

By this time, the wreckage of the downed planes had been swept away, and the traces of the mess were covered with snow. The crashed planes were all in the suburbs and did not affect the urban area, although the citizens saw the sky dragging the smoke and heard the loud explosion, but there was no air raid siren, they did not panic, and even thought that the enemy planes were of little use.

As the planes flew over the twin cities, Dong Ku received another report, and a few minutes later, the observation post reported that the planes had been diverted.

Dong Ku checked the location of the diversion on the map, and he overturned the idea that the enemy planes would bomb other targets, because if the bombing of Qiqihar would not divert from that position, it would be tantamount to a long detour, and the only explanation was that the other side would attack Harbin from all directions.

"Good! Come on!! ”

Dong Ku slammed his fist on the table. Heroic.

Subsequently, the anti-aircraft positions and trucks were dispatched one after another, and the trucks gathered in the barracks in the urban area, waiting for the position to be transferred, and the concealed anti-aircraft guns on the edge of the urban area were all camouflaged, and the barrels of the guns stretched out into the sky. The whole of Harbin is like a frightened hedgehog, with spikes erected one after another.

The air raid sirens sounded again, and the soldiers and staff of the advance army took to the streets and began to evacuate the people in an orderly manner and evade the air defense.

Many people did not cause any damage in the last air raid, and the second time the plane came, they did not raise the alarm, and shot down several planes, so they thought that there was no need to dodge. But the soldiers and staff of the advance army persuaded them into hiding places.

In less than half an hour, Harbin once again became an empty city. Even those who did not leave their homes had to hide at home and wait for the air raid sirens to pass because of military control.

Japanese planes soon flew over Harbin. They have already seen the urban area below in the high altitude, at a height of thousands of meters, and the parallel bombers do not even need to reduce the altitude, they can directly drop aerial bombs, anyway, they will bomb large targets. It's not a warship or anything like that.

The first aircraft to approach were twenty bombers of the Nakajima series, ten thunderbolts. They attracted the anti-aircraft fire of Harbin and reduced the interception fire for the other two formations that were roundabout to the left and right. Although they didn't know that the enemy's anti-aircraft artillery was already running away from the truck, it was still necessary to attract the enemy's attention.

Just as this formation was about to enter to drop bombs and the escort lightning planes were preparing to intercept the possible air interception, a cloud of smoke suddenly burst out in front of them, like a stack of gray flowers blooming in the air.

"What is this?"

All planes saw the smoke ball in front. The speed of the flicker did not make them understand what the smoke was caused by the object, but it did not delay their vigilance, and they pulled up the nose of the plane as they saw the smoke and the plane flew into the area. Duck into higher, colder airspace to avoid unnecessary losses.

But at this moment, the cargo-colored clouds outside the porthole suddenly became dense, and at the same time, the sound of explosions came into the plane.

"Is it a bomb? Cannonball? ”

In the process of pulling these planes up, all of them had this doubt, wondering how the other party could send the bomb to an altitude of nearly a thousand meters.

But at the same time as they heard the explosion, in a violent shock, the people in the plane heard a sound that frightened them, as dense as rain hitting plantains.

"Bad ......"

The thumping and violent shaking caused all the pilots to shout in fear as they tried to lift the plane, trying to get out of the unknown airspace.

However, it was too late to do anything at this time, and the dense shells exploded around their plane, although they did not hit the plane, but the steel balls built into the shells turned this airspace into a death zone.

In the sound of knocking, the first thing that bore the brunt was the rapid appearance of a black hole in the bomber slightly below, and then the pilot was hit by a steel ball, and the bomber lost control, and as the pilot fell, it tilted sideways and fell to the ground.

The observer of a bomber was hit in the head by a steel ball from below, and blood splattered and knocked the pilot to the side, and the engine was hit by the steel ball, which ignited a fire.

"Extinguish the fire!!"

The captain shouted. They will not parachute easily, and the survival rate of parachuting will not be low, but this is an enemy-occupied area.

The pilot laboriously pushed the deceased away, trying to regain control of the plane, even if he flew back to the Twin Cities, he could parachute and land in his own defense zone.

But he suddenly found that the operation was out of order, and it was clear that there was a mechanical failure in the operating system.

"It's over......"

In the violent swaying of the plane, the pilot had just risen to the idea of despair, and suddenly his body shook, and in the sound of banging, two blood holes appeared in a row, and the person also fell.

"Skydive! Parachuting!! ”

The captain shouted, smashed the telegraph with a hammer, and jumped out of control with the rest of the crew with his umbrella bag on his back, and the fire had filled the cabin.

In the air, he successfully opened the umbrella bag, and when he looked up, he couldn't help but be dumbfounded.

There were clouds of smoke in front of him, and the explosions continued one after another, and the plane above his head was no longer silent, either falling to the ground in smoke or igniting a fire in the air, believing that the explosion was only a matter of eight minutes.

Smoke billowed in the sky, thirty planes. In the dense sky net made of steel balls, not a single one was spared, and most of the pilots and entourage of the bomber crew were directly killed in the plane, and a small number were able to parachute.

Several loud bangs shook the space, and the three bombers on fire had apparently exploded.

The furious shock wave curled several parachutes near them into a curl like dead leaves blown by a strong wind. In the terrifying howls of those people, they accelerated to the ground.

The dozen or so pilots who were lucky enough to be alive did not wait to congratulate themselves on being far away. Untouched by the explosion, there were countless holes in the parachute, and the moment the screaming sound passed through their ears, they suddenly accelerated, dragging the parachute that had lost its effect like a cannonball, and fell to the ground.

"Falcon, move five to complete the mission. Please instruct! ”

"Falcon, move six to complete the mission, please instruct ......"

In the headquarters, shouts came from the walkie-talkie. These are the first interceptions made by those vehicle-mounted anti-aircraft guns, requesting instructions for the next target.

"Move No. 3 to No. 10 to evacuate the battlefield and assemble at the No. 5 location west of the city, you only have five minutes."

Dong Ku calmly shouted on the walkie-talkie. Then he grabbed the phone and ordered: "All mobile anti-aircraft artillery is assembled at the eighth position at eleven o'clock, and no plane shall be allowed to fly through the first line of defense." Fuse a thousand to two thousand meters in height! ”

"Yes!"

There was a loud command on the other end of the phone.

It turned out that three formations. One of them flew right past the industrial park where the bungalow, Dong Kuyan could get them closer?

The telegram of the first formation did not have time to be sent, and they were destroyed only in a minute or two, and in the panic, there was no time to generate electricity at all, only the shouting of walkie-talkies in close proximity. It was heard by the other two formations.

Knowing that the formation might have encountered an accident, the two formations did not pause, continued to maintain an altitude of 1,500 meters, and flew towards the set target. They believe that in a few minutes, Harbin will be on fire. There is no force that can stop the intensive bombing of more than 100 bombers, not to mention razing Harbin to the ground, but it will not be too far behind.

But how did they know that this airspace had been classified as death airspace by Dong Ku, and no plane could fly over Harbin in the sky net woven by Dong Ku, at least not yet.

Shinkyo Ogasawara also received a telegram from the bombers, saying that he did not stop the air raid on Harbin, and even if none of the 200 planes could return, he would not back down.

The bombing formation that received the order was much more cautious, and therefore increased its flight altitude by 500 meters, but they did not know what to do, even if they were raising 5,000 meters, they could not stop the fate of annihilation, and the only difference could be that it disintegrated in the air or fell to the ground and exploded.

The formation on the south side first approached the bungalow area, they didn't know that there were such a large number of buildings in the distance from Harbin but from Harbin, and they didn't know that the road was a forbidden area, so they thought that they would reach the sky over Harbin one step ahead of the brigade on the west side, but unexpectedly, just as they were preparing to fly over the bombing, an explosion sounded into the ears of everyone in the cabin.

The sound of the roaring engine could not drown out the explosion, and then clouds of smoke appeared in front of them. They reacted like the first formation, struggling to pull the nose of the plane to avoid accidents.

The only difference is that these lightning strike planes, at the moment when something strange appeared in front of them, quickly lowered their altitude and tried to cover the bombers. As long as they are given five minutes and a speed of more than 200 kilometers per hour, the bombers will be able to fly over Harbin and drop the bombs.

However, they knew that the moment the clouds appeared, there was no safe place in front of them at a height of a thousand meters.

As soon as the plane moved, dense clouds of smoke appeared in the explosion, and the air vibration reminded the plane of the turbulence of the sound of thumping, and the urging sound made all the pilots struggle to control the plane without discomfort, trying to rise and leave the airspace in front.

However, although the speed of more than 200 kilometers per hour can be regarded as a turtle speed in later airplanes, after all, it is also the speed of three holes in a minute, and when they saw the smoke cloud and heard the explosion, they had already rushed into that area, and they hit it headlong in the face of the dense rain of steel balls.

"We've been hit!!"

The pilot of the bomber, while breaking the wing, shouted in horror.

A lightning striker that had just been pierced into the ground burst into flames, apparently hitting the fuel tank or the flammable part of the engine.

"I've been shot!!"

The pilot shouted over the pager as he struggled to get out of the cabin.

But before he could leave the cabin, the fire enveloped the entire plane. Then there was a loud bang, and a cloud of fireworks exploded in the air.

At this time, there are no aircraft that can get out of this area, turn, pull up, dive. They struggled and made all sorts of efforts to try to escape the Ascension.

But there are nearly 100 anti-aircraft guns here, and all of them are new anti-aircraft guns, and the five-shot continuous firing device makes the twin anti-aircraft guns comparable to machine guns, and a hundred anti-aircraft guns are 200 barrels, and the shells poured per minute are enough to be counted as bullets.

The dense barrage of steel balls shattered all the ideas of the Japanese army. One after another, the planes became fireworks in the air, the wings of one after another were broken, and they fell from a high altitude in a whirlwind, and one after another the planes lost the control of their pilots and flew down to the ground crookedly.

"Call the 3rd Bombing Formation, call the 3rd Bombing Formation! We have been intercepted by unknown artillery fire, so don't get close to the bombing target, you can't get through!! ”

Inside a bomber that was already smoking. The captain ordered all the bombs to be unloaded and fled. While calling for another bombing formation that was already on the verge of arriving in Harbin.

But at the sound of his shouting, the plane shook violently, and then in the loud bang, the bomber was engulfed in flames, followed by an earth-shattering loud bang, and the violent shock wave blew up the fragments of the plane in all directions. Apparently the one they were transporting was hit directly by the shell.

In the dense shell explosion, one plane after another was lucky to be hit directly, and fireworks exploded in the air, just like that clear sky covered with thick smoke, like a curtain. The shadow of the blue sky is no longer visible.

The lightning planes were much faster, but they were more likely to be damaged by the steel balls and kill the pilots, causing the 20 attack planes to fail to show their skills, and in the barrage they either smoked and caught fire, or the wings were broken, and then the pilot no longer cared about his plane, allowing the planes to plunge into the densest area of the steel balls, and then exploded.

The attack came too fast, and in less than a minute, the formation of planes that had been rumbling lost control of the planes in the artillery fire. Sixty Nakajima bombers and twenty-five attack planes all turned into broken paper warblers, or fireworks, which became burial objects in this airspace.

Just as the interception had been completed here, and all the planes had been successfully shot down, the other formation had already begun to turn around.

But they didn't know that the artillery fire on the ground could be moved, and at the moment when the formation received the warning, terminated the mission, and prepared to return home, a dense explosion appeared around the aircraft formation.

"Lifting !!"

The miserable shouting of the short-range walkie-talkies of another formation had already been heard, and all the lightning strikers had already abandoned the bomber formation below at this moment, trying to drill into the clouds first and then make plans.

But how can marbles that have blocked a kilometer of height allow them to escape?

The plane was jolting, and there was a terrifying thud from the fuselage, followed by unidentified objects burrowing into the plane, tearing apart the fragile airframe, killing the pilot, hitting the engine, and breaking the wings.

Shinji Kumamoto, a Japanese pilot in the middle of the formation, was relatively lucky, and at the same time as five or six holes appeared in the fuselage in the sound of banging, he successfully pulled the plane up, and in the sound of the plane explosion below, in the smoke clouds that kept rising from the left and right, he luckily drilled into the clouds, and then rushed to the limit of elevation.

He didn't care about his companion, he didn't play a role in this hellish place, he saw the handheld explode to pieces in the smoke, and he witnessed his companion's head shatter as he spewed blood out of the porthole. All he could do now was run for his life, although he didn't know if he would be able to escape and ascend to heaven.

Shinkyo Ogasawara had already received a request from the third detachment, and as soon as he agreed to return home, a telegram came from the formation that it had been bombarded by an unknown shell, and immediately after contacting the flight formation, there was no movement, less than a minute before and after.

Fifty trucks were concentrated in the open field west of the city, which had cleared out a large area of snow, and the barrels of the guns were still spewing flames, because they could still hear the sound of the plane's engine, which showed that there were still planes in the sky that survived.

But they delayed the fuse of the shell to the limit, and when they shot into the air in batches, they heard the sound of the engine going away.

"Ran away?"

With the order to stop firing, all the antiaircraft artillery fighters cheered excitedly as they looked at the smoke in the sky, at the fire that broke out from the downing plane in the distance, and at the soldiers who were holding the poles and rushing to the position where the parachute was about to land.

This is a great victory, although they have run a few planes in the road, but they have done their best, and the results are brilliant.

"I don't know how many fights I have run?"

After receiving the report, Dong Ku said in the command headquarters: "It seems that our secret weapon no longer has secrets to speak of, and the only way to do so is to increase the density to resist the air raids that will come." ”

Liu Yucheng looked at the map under Dong Ku's hand, frowned and asked: "Captain, although it is a great victory, but the little Japanese know that our air defense means, won't they lower their altitude to dodge the shells?" ”

"Yes."

Dong Ku replied without hesitation, and added at the moment when several people looked at him: "The fuse of the anti-aircraft artillery is the flight distance and nothing else, they can break through the high-altitude barrage interception by flying at low altitude, but the anti-aircraft gun can reduce the elevation angle and shoot at the aircraft, and the barrage can also block them, plus the help of the machine gun, the air attack is still a joke, unless they have a high-altitude bomber of more than 10,000 meters now, otherwise, the existing interception means cannot be solved in the short term, and the armor will not work."
