Just ten minutes after Dong Ku's order was issued, the antiaircraft artillery truck left Harbin and headed straight for Qiqihar, when the air defense post in Shuangcheng suddenly received news that Japanese planes had dispatched.

"Have you discussed it?"

Dong Ku frowned, vaguely feeling that this was premeditated.

The sudden appearance of Soviet and Russian planes was already very strange, and both targets were bombed twice, and it was obvious that the airfield would not exceed a distance of 200 kilometers. And as soon as the bombing over there ended, the Japanese came here, as if they were waiting for the air defense power on this side to be withdrawn.

"Come on!"

Dong Ku pondered for a moment, roared in a low voice, grabbed the phone and gave the order, and entered the air defense preparations.

The air raid siren, which had been suspended for nearly a month, sounded over Harbin, and the whimpering iron cat made the ten gates not to mention, and then rushed to the air defense bunker in an orderly manner. There are also people who are bold enough to hide in their homes and not join the flow of people.

Dong Ku was close to the phone, still holding the headset of the walkie-talkie in his hand.

Not long after the air raid sirens sounded, the report of the observation post sounded again.

"The shape of the plane is monowing, it is a flamingo, it flies at a low altitude, it is extremely fast, and there are thirty of them."

Flamingo?

Dong Ku was stunned. The Japanese tested performance with a new attack aircraft?

He knew that the machine guns of fighters that swept at low altitudes were even more effective, and if the anti-aircraft guns were not for his projectiles with steel balls built, they would still be ornaments, and they could only be strafed by attack planes. But the Japanese apparently did not know that the Flamingo was also unable to break through the air defense, even if it was fast, it would be in vain.

With Dong Ku's order, one after another drove out of the concealed place and drove to the predetermined position, the muzzle of the gun was lowered, almost flat fire, and the elevation angle was not even fifteen degrees.

"A thousand meters of delay. Get ready!! ”

Dong Ku calmly ordered.

With the roar of the motor, the flamingo's fast-flying figure appeared in the rear air defense post. The Japanese aircraft did not attack Shuangcheng, but still went straight to Harbin.

"One to three sets of preparations!"

"Group 4-6 Second Batch ......"

With one command after another, anti-aircraft guns roared on the air defense line in the direction from which the three Japanese planes were flying.

The projectile flew rapidly, and in the blink of an eye, it reached a kilometer. Then the clouds of smoke exploded in the air less than a hundred meters above the ground, and before the steel balls could completely disperse, a second wave of shells flew in and exploded......

Waves of cannonballs continued, and in a few breaths, it became an area where steel balls raged.

Just at the stall where the steel balls were flying all over the sky and clattering, flamingos, which were not even more than 100 meters at low altitude, appeared in that airspace, like arrows. plunged into the big net woven by steel balls, and before he even had time to react, he was shredded by the dense steel balls, discounted the wings, and plunged to the ground without hesitation.

The formations that followed did not have time to climb to dodge, and they were shot one after another, rolling in the smoke one by one, without waiting for a fire. Before it could smoke, it plunged into the ground. Then, with a loud bang, a sky-high flame erupted on the ground.

"Pull it up! Pull it up!! ”

The two formations on the left and right wings behind saw that the leading formation at the head had been intercepted, shouted, pulled the plane up, and tried to avoid the death zone.

But the flamingo is too fast. The moment he saw the plane in front of him being intercepted, he didn't wait to pull up a height of dozens of meters, and plunged into the area of smoke, followed by a shout of fear, like dumplings. Pierced to the ground, and flames erupted.

The two flamingos luckily took advantage of the cover of the bodies of their comrades in front of them to avoid the interception of the steel ball net, and in their hearts, they soared into the sky and went straight to the clouds.

"Ran two?"

After receiving the report, Dong Ku was surprised. This method of intercepting low-altitude attack aircraft, it is difficult for the thin-skinned Zero to escape, which shows how good the luck of these two goods is.

"Watch, if he lingers in the airspace, beat him down!!"

knocked out more than 20 zeros that were estimated to be bought by small Japan with a lot of money, Dong Ku felt a little more comfortable, and the depression of the air raid on Callan was somewhat spit out.

Two flamingos that escaped to the sky flew directly over Harbin from an altitude of seven or eight thousand meters, and the rumbling sound of the motors made the people in the shelter sweat, and they didn't know how fierce the air raid would be.

But after waiting for five or six minutes, no explosions were heard, and apparently, the air raid did not come. Subsequently, the air raid siren was lifted.

When they took to the streets, the smoke in the distance made them realize that the air raid was not coming, but was intercepted by the advance army.

The two planes that escaped with their lives went around in circles directly over Harbin and quickly left here. They didn't dare to risk descending.

The air raid alarm contacted, Dong Ku left the headquarters, called Liu Zhong, and prepared to arrange, he personally went to Calland to see, the number of artillery destroyed there was too large, and the artillery for Lao Jiang had been transported, and there was a shortcoming in the suppression of firepower, and the advance army would endlessly carry out close attack and defense with the Soviet and Russian troops, which could not be consumed.

Let Liu Zhong arrange to transport the 105 heavy cannons and most of the 15-kilometer range artillery in Suifenhe back to Harbin for refitting, and take advantage of the freezing at night to transport them to Mongolia as soon as possible, otherwise it will not be possible to transport the bulky artillery for half a month. Most of the Tiger Head's long-range artillery was dismantled and shipped back, and it was also transported to Mongolia.

He knew that Mongolia would be the main battlefield for the defense of Soviet Russia in the future, and that Soviet Russia would no longer risk stationing troops along the Hutou line, so that once his railway was cut off, the large troops left behind might be dumpled.

As soon as the arrangement was completed, Lao Zhao suddenly called and told Dong Ku that he had been attacked by attack planes, killing and wounding hundreds of soldiers and poor people, and that the planes had beaten one and one had fled.

"Two?"

Dong Ku paused and said: "I just shot down twenty-eight planes here, and that one escaped from here, I didn't expect to go around you without giving up." ”

"Okay......"

Lao Zhao was speechless for a while. When people slipped through the net, they went to him to make it rainy, and they also caused casualties.

They didn't take the flamingo seriously, but the Japanese blew it up.

When the last flamingo landed at Xinjing Airport, all the top Japanese officials were stunned.

This is not a little bit faster than the previous new plane, after testing, the old Nakajima is a tortured in the air, according to their imagination, the speed of the plane to break through the opponent's defense line is absolutely no problem, even if you lose a few, you can use the machine guns on the plane to destroy most of their anti-aircraft guns with speed. But now it is still impossible to break through the opponent's defense line, even if the last two planes raided Qiqihar, the moment the other party reacted, only one of the two planes escaped back.

This shows that their only reliance now has also lost its effect, and it seems that it is not an ordinary difficulty to attack Harbin, and I am afraid that they will really have to be blocked on this side of the river.

If the warships could drive in, the Songhua River would not be able to pass such a large tonnage warship at all, and besides, the warships might not be able to block the opponent's round of shelling.

The flamingos, which had high hopes, lost their effect, much to the discouragement of the Japanese. The higher-ups have realized that they are in trouble now. The advance army can't be defeated, and it will be difficult to deal with it if it grows bigger, and there will be two or three months of muddy roads for them to develop with peace of mind. On the veteran's side, the advance army seems to consciously support their weapons, and if this continues, the strength of the veteran's army will increase greatly, and the threat to Manchuria will be too great, after all, once the war starts, it will be a two-sided attack.

Just when the news reached the mainland, and the flamingo could not break through the other party's interception and could not carry out an air attack, Terauchi Shouichi, who had been dormant for several months, took possession and strongly expounded his own views, so that the Japanese high-level began to waver in the case of the flamingo folding its wings, and gradually, the center of gravity began to favor Terauchi Shouichi.

Dong Ku didn't know what had changed in the Japanese leadership, and the wave of Japanese troops he had let go of when Harbin City was broken earlier had installed more than 30 students who were proficient in Japanese and had undergone professional training into the Japanese army, but unfortunately, their ranks were too low to find out the contents of such a confidential cabinet meeting.

After Dong Ku lost the effect of the Zero, he had already determined that the Japanese army would not launch another offensive under the premise that it could not restrain his artillery, and the losses were unnecessary and could not be recovered. After talking to Lao Zhao on the phone, he set off for Mongolia.

At this time, there was a tense atmosphere in Mongolia, and all towns were set up with machine guns to prevent Soviet and Russian bombing. Those heavy machine guns and anti-aircraft machine guns were also propped up. The anti-aircraft guns will have to wait, and it will take at least ten hours to be in place.

At the same time as transferring the army to deploy defense, Goudan transferred some artillery from the surrounding area to increase the long-range fire suppression capability of Charlan and Turga, and concentrated all the remaining medium-range artillery sold to Lao Jiang in Türta and Charland to prevent the attack of the Soviet Russian army.

At the same time, several reconnaissance teams sneaked out of the border to find the Russian airfield. If they don't knock out the airfield, it will be very difficult for them, and even if the anti-aircraft artillery arrives, once the enemy planes break through on all sides, they will not be able to prevent it.

After the bombing, Soviet Russia was also unable to launch any more air raids, and a total of 210 bombers actually let the advance army shoot down most of them, or with machine guns. This puzzled them, it was very difficult for machine guns to hit planes, and they couldn't aim at all, how did the advance army do it?

In fact, the amount of advance is not a sophisticated technique, but there was no systematic summary at that time, even if it is a rifle, it can hit a slow-flying bomber, but the size of the damage is just the size.

The number of bombers was not enough, so Soviet Russia chose to wait, and when reinforcements arrived in Siberia, and then launched an air attack, it would not be long, at most it would arrive in the second half of the night, or the ground would not freeze, and the planes would not be able to take off and land.

Their airfield was improvised and secretive, nearly a hundred kilometers from the front line, and it was very well defended.

However, although the Russians were well guarded and did not underestimate their opponents, their airfield was quickly discovered by the reconnaissance team of the advance army. (To be continued......)
