(PS: The new week has begun again! Please vote for support! It’s another one o’clock in the morning. For the sake of hard work, you all support it! No matter how small the mosquito is, it’s still meat! Hehe!)

If you want to ask what it feels like to fall from heaven to hell, the Japanese pilots running around Yan'an at this moment have the most experience. I thought they would go down to the Eighth Route Army air defense firepower that had already lost their protective covers.

As a result, when she went on with excitement, she suddenly found that Miss Hua, who had nowhere to escape, suddenly turned into a burly man with thorns all over her body. Perhaps only these Japanese pilots had the most experience of this loss and pain.

Even facing anti-aircraft guns that occasionally rush into high altitudes, many Japanese bombers watching the battle hurriedly increased their bomber height like frightened little ducks, for fear that an anti-aircraft gun would penetrate their planes by accident.

Compared with the range and power of anti-aircraft machine guns, the range and power of anti-aircraft guns are undoubtedly higher and greater. The crossfire formed by the sixteen anti-aircraft guns makes these Japanese troops fighting for food like flies hitting into a spider web.

Many anti-aircraft machine gunners who watched the game couldn't help but clenched their fists and said, "Damn it, you're good at fighting! I really think our machine gun battalion is easy to bully. Now I know I'm fooled! The machine gun that was finally seized was blown up by the Japanese."

Listening to the complaints of these machine gunners, the officer who was in the machine gun position comforted him: "Don't be sad! At this moment, isn't the anti-aircraft artillery battalion avenged us? As long as people are alive, the teacher will send us anti-aircraft machine guns in the future."

For these air defense battalions, He Zhengdao is their respected teacher. Nowadays, many of the advanced equipment of the guard division are selected from the seized materials by He Zhengdao, and is given priority to the equipment for them.

Standing outside the temporary command center and looking at the Japanese planes that fell from time to time, Chen Geng said excitedly: "Beautiful! This is the happiest air battle I have ever seen since I have been in the army. Damn, the Japanese are today!"

He Zhengdao said calmly about Chen Geng's excitement: "Old leader, it's too early to be happy now. This tactic can only be used once. I'm afraid it won't be that easy to think about the Japanese devils in the future.

After all, our air defense firepower is still too weak. If there are large-caliber anti-aircraft guns, these bombers that are still in the sky can completely kill them. They even dare not lower the altitude and bomb.

The most important thing is that the ammunition we seized is difficult to organize such an air defense battle again when the air battle ends this time. I hope this time can scare the Japanese and give us more time to develop!"

Compared with rifles and mortars, the machinery and equipment of the Taiyuan Arsenal were seized, and as long as the steel plant was established, it was believed that it could be developed smoothly. However, the anti-aircraft guns required a higher technical requirement.

At least in He Zhengdao's view, before developing a Zero fighter jet that could suppress the Japanese Zero fighter, the Eighth Route Army could only adopt a passive defense policy. Collect more air defense weapons and build a more powerful air defense firepower network.

Only by developing an aircraft that can suppress the Japanese Zero fighter jets can the Eighth Route Army regain air supremacy in North China and eventually launch a comprehensive counterattack against Japanese soldiers. However, if we want to develop aircraft, this technical requirement will be even more difficult for the current arsenal.

Fortunately, He Zhengdao knows that the central government currently attaches great importance to talents. From abroad and at home, many professors and scholars have been hired. The arrival of these people will surely improve the R&D capabilities of the arsenal in a short time.

In addition, He Zhengdao, who came from later generations, can provide these R&D personnel with some research directions and references to shorten the time for this kind of research and development. But even if the time is short, it is impossible to produce an aircraft within at least one or two years.

When the anti-aircraft anti-aircraft guns on the ground stopped firing, they looked at several fighters that finally escaped the firepower network. The Japanese pilots who performed this flight mission felt a little lucky to have escaped.

As for the pilots who were in charge of the previous command, they had unfortunately reported from their team. The Japanese pilot who took over their command immediately guided the bomber to carry out high-altitude bombing below.

At this moment, the smoke shrouded over Yan'an City seemed to have become thinner. For these Japanese bombers carrying out high-altitude bombing, the officers and soldiers of the anti-aircraft artillery battalion could only choose to avoid temporarily.

Compared with anti-aircraft machine guns, the air-raid shelters built by these anti-aircraft guns are more spacious when setting up artillery positions. The officers and soldiers responsible for these anti-aircraft guns dragged and pulled the anti-aircraft guns into the air-raid shelter.

In fact, when they saw the Japanese fighter jets flee from their fire range, many shooters who controlled anti-aircraft guns began to transfer these anti-aircraft guns. For them, these anti-aircraft guns have too much effect, and it would be a pity to lose one!

At the same time, all the anti-aircraft machine guns retained on the anti-aircraft machine gun positions were dismantled and moved into the air raid shelter. For the Eighth Route Army, the thrifty family-run Eighth Route Army, it is extremely precious to keep such a weapon.

Looking at the air defense position shrouded in the smoke of the explosion, He Zhengdao said with a little concern: "I don't know what the losses of our two air defense battalions this time. These two air defense battalions were finally formed!"

Listening to this, Chen Geng nodded and said, "Yes! Especially the anti-aircraft artillery battalion, each anti-aircraft artillery is rare. I hope they can drag those anti-aircraft artillery into the air raid shelter before the explosion.

Before this air defense battle started, I thought it would be a bit waste to build an air raid shelter for each anti-aircraft gun. Now it seems that you have the foresight. As long as the people from the air defense battalion are alive, they can restore their combat effectiveness as long as there are air defense weapons in the future."

‘Hope is too late! The old leader, sounded the warning for comprehensive air defense. Next, the Japanese are afraid that they will bomb Yangjialing. In this situation, I can only expect the Japanese to delay a little longer and buy time for our Air Force to come and buy time.’

Just as the people in the air raid shelter were watching when the air raid ended, another larger air raid sirens sounded throughout Yan'an City. Hearing these different air raid sirens, the soldiers responsible for the safety of the air raid shelter knew that the real air raid had begun.

He turned to the people of the air-raid shelter and said, "Members, please stay calm! Our air defense force had already fought with the Japanese airplanes. Next, the Japanese airplanes were about to start bombing us.

Please stay here with peace of mind. The Japanese lost a lot of bombs on Phoenix Mountain. I believe that next, they will not have too many bombs to throw them into other parts of the city. Wait a little longer, the air strike will end soon."

In fact, another function of comprehensive air defense early warning is to remind the troops outside to enter the air raid shelter. As for this time, some people want to break into Yangjialing, so they hope that he can be lucky enough to escape the attack of air bombs.

What's more, machine gun castles were also set up on the road entering Yangjialing. These bunkers can also withstand the bombing of aviation bombs, and can also block the armed personnel entering Yangjialing during air strikes.

In general, when He Zhengdao used Yangjialing as the central garrison, he fully considered the issue of security. If he wanted to successfully attack Yangjialing, it would be possible to attack Yangjialing without the enemy having a two-pronged attack with aircraft and heavy artillery.

If there are fewer people, if the enemy wants to successfully attack Yangjialing, they will know what it means to kick the iron plate. Therefore, a comprehensive air defense warning alarm sounded, including the lurking saber special forces, all entered the air raid shelter closest to them for a temporary escape.

In short, the comprehensive air defense warning also means that the Eighth Route Army will be powerless in the air strikes of the Japanese. They can only stay in the air raid shelter and allow them to bomb at will. This can be regarded as a helpless retreat signal!

Seeing the end of the bombings, Yangjialing ahead had already appeared in the sight of the bomber formation. The bomber that still preserved ammunition began to tentatively lower the altitude and carry out concentrated bombing on Yangjialing.

Realizing that the ground had no air defense firepower, the Japanese fighter jets, who had previously felt very aggrieved, also joined this kind of ground attack, hoping to shoot the troops on the ground to vent their anger.

Unfortunately, when the comprehensive air defense warning sounds, all personnel on the ground must enter the air raid shelter. This also means that, except for some houses, they cannot see any living things at all.

Just as the Japanese pilot who was taking over the command ordered the bombers to bomb other key targets in Yan'an City, the Eighth Route Army Air Force fighter fleet departing from Yulin had already arrived in Yan'an airspace.

Staring at the Japanese bombers raging above Yan'an City in front, Zheng Shaoyu, who led the team, first descended the altitude and attacked the Japanese bombers in front. The remaining fighters began to hunt in groups in two groups.

Just as these Japanese bomber pilots were confused, these thirty fighter planes flew from there. Looking at the fighter planes flying in and began to fire deadly machine gun bullets, these Japanese bomber pilots were suddenly disintegrated.

‘Baga, this is an enemy plane! This is a fighter plane of the Chinese army! Avoid, avoid!’

Seeing several off-guard bombers being blasted by fighters rushing out of the clouds, the remaining bombers began to scatter, hoping to escape the hunting of these fighters.

The Japanese fighter pilots who also saw this scene, even if they knew that they would find it difficult to go back alive today, they could only bite the bullet and fight against the Eighth Route Army Air Force that rushed to the scene.

Compared with the fighter jets in the Japanese bomber formation, the Eighth Route Army Air Force, which had sufficient ammunition and high morale, was able to deal with these entangled Japanese fighter jets in groups.

Standing at the door of the temporary command center, He Zhengdao looked at the fighter plane fighting over Yan'an City. When he saw the Japanese plane falling, he couldn't help but cheer. Seeing his fighter plane falling, he felt secretly ache in his heart.

I also knew that these fighter jets appeared and that the Japanese bombers who had completely failed were able to do was to leave quickly. Compared with the flexible maneuver of fighter jets, bombers would undoubtedly be at a disadvantage when fighting against fighters.
