"Woooooooo..."

Urgent and harsh air raid sirens suddenly sounded in major cities in southeastern Shanxi.

After listening to Song Li's detailed report, Xie Chengrui immediately decided to sound the air defense alarm.

There were at most two targets in Shanxi that could allow the Japanese army to mobilize forces like this. One was Jincheng, the administrative and military center in southeastern Shanxi, and the other was an industrial base that was being continuously improved and improved.

Less than half an hour after dawn, experts, workers, students, soldiers, etc. in various cities have just woken up, and about 20% of them are still lying in bed.

In the cold winter, people instinctively stay in bed, and the sound of air raid sirens scares everyone.

After Jiangdong took control of southeastern Shanxi, this was the first time the sound of air defense sirens appeared over the city.

Some people who had been at ease for too long were stunned for half a minute before they ran to the nearest air-raid shelter with their whole family as if they had just woken up from a dream.

The perfect civil affairs system played a great role at this time. Government officials commanded and organized the people in an orderly manner, greatly reducing casualties caused by stampedes and other panic behaviors.

"Chief of Staff, the observation station ahead has still not seen the Japanese aircraft. The morning fog in Gaoping has not completely dissipated. Lingchuan is slightly better.

Air defense units are in place!"

A communications staff officer spoke quickly.

"Have the Soviet Union, Germany, the United States, and our own experts entered the air-raid shelter?" Xie Chengrui asked.

"They are the first batch of people to be evacuated. Don't worry, arrangements have been made!" Wu Zhan replied quickly while recording something.

Song Li looked at his watch and found that it was less than three minutes before the estimated arrival time of the Japanese bombers. He walked to Xie Chengrui and reminded him:

"Thank you, Chief of Staff, take the brothers in the headquarters into the air-raid shelter. Although there are air defense troops in front, there is no guarantee that everything will go wrong."

Xie Chengrui looked around at the people around him and saw that no one showed any panic or panic expression. He nodded secretly in his heart and then said:

"Old Wu, Old Song, you lead everyone to retreat, I will go to the roof to check the situation."

After he finished speaking, he grabbed the binoculars and walked out without giving anyone a chance to speak.

Wu Zhan and Song Li looked at each other, and both saw the reluctance in the other's eyes, but they quickly organized the staff and confidential personnel in the headquarters to evacuate.

"If the Japanese's goal is Jincheng, should this point be reached?"

Song Li, Wu Zhan and Xie Chengrui stood on the roof. The former glanced at the northern sky and said.

"Damn it, did you really go to Lingchuan and Gaoping?"

There was no fog in the sky in Jincheng, and one could see very high and far away, but no one saw the shadow of the Japanese bombers.

"Ask about the situation of Gaoping and Lingchuan, don't let your guard down, wait another 5 minutes!"

Xie Chengrui's fingers gently rubbed the center of the telescope's eyepiece and objective lens.

…

…

There are four 88mm anti-aircraft artillery regiments in Jiangdong, and these four regiments are all under the command of Liu Dagui's Air Defense Command.

When he started planning to build his own industrial base, Koto guessed that the Japanese would probably send long-range bombers to carry out air strikes.

Therefore, after the 88mm anti-aircraft guns of these four regiments arrived, he did not transfer them to the front line, but stayed behind.

One of the four regiments is based in Wuxiang. The main task of this group is to guard against Japanese aircraft heading south.

However, the weather in Wuxiang and Gaoping is similar. It is easy to get foggy in the morning. Moreover, based on the time, it is likely that it will still be dark when the Japanese bombers pass through Wuxiang.

The anti-aircraft artillery group in Wuxiang found nothing except hearing some slight movements.

"Are you sure you heard the sound of a plane and not a fucking bird?"

In the air defense headquarters, Liu Dagui asked the commander of the 1st Anti-aircraft Artillery Regiment loudly into the microphone.

The voice on the other end of the phone was a little hesitant,

"Commander, the soldier on duty seems to have heard what he said. I asked him several times and he still gave the same answer!"

"Grandma, what do you mean, it seems like, I will remove this person from the observation post today, trash!"

Liu Dagui hung up the phone fiercely, and then asked:

"Has anyone seen the Japanese plane?"

The people in the headquarters were stunned for a moment and then all shook their heads. None of the observation stations they were responsible for contacting noticed the situation.

The Air Defense Command is located in the mountainous area north of Lingchuan and Gaoping. The soldiers spent two months secretly hollowing out a mountain and then moved all the headquarters' belongings into the mountain.

Such a location is safe and hidden, and almost no one can find it.

Liu Dagui quickly rushed out of the mountain and stood on the observation platform covered with camouflage nets to watch.

…

…

"Squad leader, there seems to be something in the sky. Look to the northeast!" From an observation point further ahead, a soldier shouted with excitement and joy.

Hearing the shouts, four or five people simultaneously held up observation glasses and looked northeast.

Through the clouds and fog, you can vaguely see the outlines of some black shadows in the sky.

Those shadows seemed to be dropping in height at extremely high and far places. The squad leader at the observation point almost jumped up with excitement. He loudly said to the communication soldier:

"Immediately report to the headquarters that Japanese aircraft were found, the number is unknown, the heading..."

All the soldiers at the observation point were in a state of extreme excitement.

It has been several months since the establishment of the Air Defense Command, and they have been at this observation point for at least a month. The most common thing they do every day is to listen with their ears pricked up and look through the observation glass. They are like looking forward to the stars and the moon.

Looking forward to the Japanese plane coming and giving them a surprise.

When I received the intelligence this morning, all the observation points were in a state of excitement. Masturbation is the favorite and best thing of all air defense fighters.

Liu Dagui's cheeks turned red with excitement when he heard the news coming back from the observation point.

"The Second Anti-aircraft Artillery Regiment is ordered not to let a Japanese plane pass through their defense line, otherwise I will remember everyone to be punished!"

The 2nd, 3rd and 4th regiments of the 2nd Anti-aircraft Artillery Regiment were distributed around Lingchuan and Gaoping, generally arranged in a triangle, in order to create a firepower network so that Japanese aircraft could not find any gaps.

…

"Arrived over the target in three minutes, all aircraft descended and prepared to drop bombs!"

The Japanese colonel gave the order in a calm tone.

Twenty Japanese bombers began to slowly descend in altitude, and ten fighter jets were distributed around the bombers, doing the same thing.

High-altitude bombing is safe and enjoyable.

It is especially satisfying when you see the cannonballs falling on the ground and exploding countless red flowers. The scene is like the pilot reshaping the earth and the world in the posture of a god.

The more than 100 little Japs on the plane all smiled. They would descend to an altitude of about two thousand meters to drop bombs.

It is rare to see anti-aircraft weapons on the Chinese battlefield, not to mention that now they are almost absolutely safe at an altitude of 4,000 meters.

The machine gunners everywhere on the bomber were waiting a little boredly. The Chinese Air Force had been completely depleted. These machine gunners were often just decorations, and it was difficult to have the opportunity to directly participate in the battle.

A young Japs machine gunner turned the muzzle of his gun toward the ground out of boredom, and made a beeping sound from his mouth, as if he couldn't wait to shoot the bullets in the gun chamber to the ground.

At a certain moment, the Japs machine gunner's eyes suddenly narrowed, and something in the mountains below seemed to be shooting at his eyebrows at an extremely fast speed.

"Be careful! Anti-aircraft guns..."

The machine gunner's voice suddenly stopped because an 88mm high-explosive bomb exploded more than 10 meters away from the bomber. The flying shrapnel split open the glass cover of the cabin like a knife and cut off half of the machine gunner's head.

"Boom boom boom..."

Dozens of anti-aircraft artillery shells equipped with both proximity fuzes and delay fuzes exploded at various locations in the Japanese bomber formation.

"Dangdangdang..."

The sound of shrapnel hitting all over the cabins of all Japanese aircraft suddenly sounded.

Because the Japanese commander mistakenly believed that the industrial bases in Lingchuan, Gaoping and other places did not have air defense systems, the flying altitude of the bomber formation had dropped to less than 3 kilometers.

It was the Second Anti-aircraft Artillery Regiment that launched the attack on the Japanese bombers. The regiment's positions and all 88mm anti-aircraft guns were hidden among the mountains.

Although the little devils on the plane were attacked, few people saw clearly where the shells came from.

The 88mm anti-aircraft gun can hit aircraft at a maximum altitude of 9,900 meters during air defense operations. At present, Japanese bombers are less than 3 kilometers away from the ground. At this distance, the power of the 88mm anti-aircraft gun can almost be described as terrifying.

The artillery shell will fly in the air for about 3 to 4 seconds, and then the proximity fuse of almost all artillery shells will be triggered.

"Boom boom boom..."

The exploding shells turned the airspace into a sea of ​​metal fragments. The outermost bomber's wing was torn apart by countless shrapnel. The 97 heavy explosion immediately tilted to the left, exceeding the top speed of 432 kilometers per hour.

Hitting the ground at a high speed.

It was hit by two 88mm anti-aircraft guns at the same time when it was about 1 kilometer above the ground. The 97 Heavy Explosion disintegrated in mid-air under the dual effects of shrapnel and air resistance. Some soldiers responsible for the observation saw the aircraft fragments

Several figures fell to the ground together.

Some of the people were falling in the wind like dead leaves in autumn, and some were dancing in the air. If the distance was not too high, one might be able to hear their screams.

"boom!"
