"Whoosh!"

Two thumb-thick 30mm caliber high-explosive bombs flashed out of the chamber at six times the speed of sound. Under the electromagnetic push, there was no spark. They hit the backs of two G3M bombers in less than a second. The sensitive warheads exploded immediately after tearing through the weak shells.

!

"Boom!" The two large balls of fire were like the explosion of 105mm grenades. They were actually five or six meters in diameter. They cut off the two planes in an instant. Most of the crew inside were caught off guard and were killed. The rest were injured and screamed as the plane smashed them into pieces.

Dragging his body straight down to the dark earth below!

The densely packed fleet of aircraft was in a panic, and the Japanese aircraft that were closer in front and behind made evasive gestures. The dozen or so night fighters escorting them even accelerated and rushed over to search left and right. There was no flash on the ground, so it must be the good work of the night fighters!

The "Parrot" did not continue to fire. Its six thrusters increased power and suddenly floated to an altitude of seven thousand meters, avoiding the front to avoid being hit by Japanese planes. It was not because of fear, but because it did not want to disrupt the planned steps.

The Japanese aircraft searched for a while and found nothing, so they continued to run forward. Although the total speed was only more than 400 kilometers, the straight-line distance from the coast to Nanjing was not much. Half an hour passed in a flash, and the second air defense line came into contact.

distance, fire with a bang!

Drawing on the previous lessons, we immediately let external forces with unlimited computing power take over the operation. Technicians far away from the "tiger's den" at the entrance of the ancient town calculated the fastest Japanese aircraft signal coordinates scanned by the defense line radar array on the big screen.

, a series of attack formations are sent back accordingly.

In the mountains and fields, air defense positions less than five kilometers apart opened fire one after another! This time, there were more than thirty imitation German 88mm anti-aircraft guns in the middle, with super long and high shooting capabilities. Their defense range was much larger than before.

It was twice as big! It was nearly eight thousand meters away, and the first wave of shells hit the middle!

With the command of unified fire control, groups of 88mm anti-aircraft guns assisted each other in groups of 36 to 36. The shells fired under the unified command gathered at high altitude and formed arc formations with a diameter of 100 meters! There are hundreds of reloading units.

When a high-explosive bomb with thousands of tiny steel balls explodes, it will create a destructive circle with a diameter of 300 meters. If three or six are connected, it will form a killing net covering a wide area!

It is almost the same as a high-altitude sniper. The accurately calculated flight trajectory of the Japanese aircraft changes into the elements of continuous attacks by anti-aircraft guns. Two shots are fired at each coordinate and the changes are immediate. In the high sky, clusters of flashes of explosions turn the planes one after another.

The Japanese machine devours!

Within a short distance of three thousand meters, the 88mm anti-aircraft cannon alone knocked down nearly thirty aircraft, which was a remarkable achievement! At a distance of five thousand meters, the long-awaited 75mm anti-aircraft cannon joined the battle group, and the firepower density was doubled!

As if the Japanese planes had expected it, the forward fighters suddenly accelerated their speed. In particular, the more than thirty "Ultimate Zero Fighters" specially equipped with night flight equipment took the lead and rushed from behind, passing by the bombers.

The seemingly chaotic and rapid maneuvers at the bottom of the group in the sky confused the signals detected by the radar array below.

The precise strikes of the anti-aircraft guns were immediately blunted. Taking this opportunity, the Japanese aircraft formation changed again. The altitude and flight direction changed, deviating from the original route and escaping from the lock.

Zhu Bin was amazed when he saw it from a high altitude. The Japanese really didn't want their lives! With their primitive infrared night vision equipment, there was a high chance of losing vision during high-speed maneuvers. It was safe to lose control and hit the ground. Fighting and other things were even more difficult.

think.

They actually went to such extreme lengths to cover the bomber group, and their fighting spirit was truly extraordinary! They are indeed a nation that gives even the great powers a headache.

However, this kind of performance is of little use to him. As soon as the fighter planes with radars come on the scene, he will fly in five hundred ways, but he still can't escape the missile attack. Everyone is destined to die, so do the last thing first.

Struggle!

Seeing the dozens of fighter planes flying around like headless flies, Zhu Bin also felt disgusted. His fingers continued to move on the screen, and eight small combat bombs only two meters long were activated. The "Big-billed Parrot"

The belly is open, and the rotating mount continuously releases the lock to release all the missiles.

The missiles that were activated immediately after decoupling ejected a shining light from the tail, and suddenly swooped down from a high altitude. They locked onto one of the "Ultimate Zeroes" and pierced them with one shot. They exploded into fireballs and fell messily.

In the dense air defense fire net explosion, these eight explosion points were not conspicuous at all, and the Japanese army did not notice anything was wrong. They just thought that the attack below was too excessive. How could someone blindly fire so accurately? Could it be that they are possessed by gods?

Not successful?

The group of bombers that accelerated their formation change and impact dropped seventy or eighty bombers along the way and swarmed through the air defense line! The Japanese planes, which had no intention of coming back even though they were on the spot, showed their desperate spirit and performed extremely well. There were more than three hundred bombers left.

Fighters of all kinds rushed forward non-stop, but Chen Cheng at the base camp was so worried that several strands of his hair turned gray!

He has once again advised Chiang Kai-shek to leave Nanjing and seek shelter in the suburbs, or stay in underground air defense fortifications first. It is really not safe here! If the opponent's fighter planes are fast enough, it will only take an hour to rush over from the sea.

, it is too difficult for the air force to intercept!

Old Chiang Kai-shek was also furious. He gritted his teeth and stayed at the base camp, refusing to leave! He even screamed, and anyone who was not deaf would not be able to hear the sound.

Chen Cheng had no choice but to call Zhu Bin himself, but the answer he received was still: "Everything is under control."

"What a mess! The Japanese plane is almost flying over the capital! Where is his plane?! Could it be that the bomb must fall on our heads for him to be satisfied?!"

After Chen Cheng finished roaring, he suddenly came back to his senses and broke into a sweat: "Yes! Why didn't I expect that! That guy probably had such thoughts! Otherwise, under such a fierce battle, how could he

Will the Japanese troops not be aware of their actions in advance?”

The result of this judgment was too scary! Chen Cheng even looked around involuntarily to prevent anyone from noticing his abnormality. His heart was beating wildly, as if he had discovered some terrible truth!

Zhu Bin, I'm afraid he really wants bombs to fall on the capital. At that time, no matter what considerations the Chairman has, he must agree to launch a larger-scale attack on Japan, especially the bombing of its homeland. This is Zhu Bin

It has been possible for a long time; even several squadrons of twin-engine bombers that the Central Air Force regarded as treasures once dropped bombs on Japan.

Well, as long as such an attack is agreed to, the scale and intensity will be difficult to control. If Zhu Bin, on a whim, makes a few more of the terrible things that blew up the Imperial University, Japan will have a lot of fun.

!

But in order to achieve such a goal, they allowed Japanese planes to wreak havoc on the mainland? Isn't this kind of behavior going too far?

Chen Cheng was a little unsure. If Zhu Bin really did that, it seemed to him that it was reasonable. In political struggle, he would do whatever he could to sacrifice some citizens. However, this seemed to be consistent with Zhu Bin's usual way of doing things.

It’s not very consistent!

He can't control that much. Anyway, he can't get involved in that level of strife. He just has to do his duty honestly.

Chen Cheng shook his head and once again confirmed that the third line of defense was foolproof. He hoped in his heart that the weapons Zhu Bin gave him and the technical team that came to help would be really effective!

The third line of defense is located to the west of Taihu Lake. Guangde and Wuxing are the first line, and Yixing is the end of the line of defense. It is thicker than the previous two lines, and its width stretches directly to the edge of the Yangtze River. Even in Taihu Lake, there are more than a dozen ships

The existence of small gunboats, suitable for both air and ground attack, and flexible, is to ensure that the capital is safe.

The three major theaters were established. Since the war in the north began, Zhu Bin sent a force to help plan the three lines of defense. A dedicated team was stationed in the third line of defense, equipped with a series of anti-aircraft firepower equipment that they only used internally.

Directly assisting the Beijing and Shanghai security forces in learning. Of course, it goes without saying that they are the most direct units in the Central Army.

Now that both lines of defense have been breached, although about two hundred Japanese planes were shot down, there were even more left! If we can't stop it, even if only a hundred planes fly over and bomb the capital, it won't be a big deal.

No way to clean it up!

The buzzing roar spread farther in the silent night. On the defense line centered on Taihu Lake, hundreds of artillery fires were waiting! The Huangshan radar station first determined the direction of the Japanese aircraft's incoming attack and the number of the aircraft fleet. Soon after,

The Wuxing position is the first to engage the enemy!

Under the colorful camouflage net, technicians from Zhu Jiajun calmly entered the number of enemy aircraft displayed on the screen and the coordinates calculated in real time on the side from the radar command vehicle with thick protective armor into the computer; five kilometers away from them

In the mountains, each anti-aircraft gun quickly adjusted its height and angle, especially the rocket vehicles deployed behind a ridge, which raised their multi-layer launch tubes and pointed them towards the dark night sky.

When the forward of the Japanese aircraft accelerated and rushed into the 10,000-meter cordon, the technician in the radar command vehicle decisively pressed the launch button, and the rocket vehicles commanded by remote control spewed out dazzling flames!

There are a total of eighteen rocket vehicles, scattered on the arc-shaped mountain ground of twelve kilometers. The 122.mm rockets fired every second drag the seemingly endless long tail flames straight into the sky, and the light emitted will cover the large area.

The valley lights up!

This is the Army's version of the "Iron Curtain" air defense system! Eighteen rocket vehicles are a combat unit. Each vehicle has an independent radar fire control servo. The timing, height, and angle of the rocket launch are carefully designed, seemingly loose.

After being launched, four to five hundred rockets crisscrossed to form several consecutive layers of firepower network. They exploded immediately after reaching a height or when the proximity fuze detected the Japanese aircraft!

Explosions erupted like thunderstorms in the airspace at a maximum of five thousand meters and a minimum of one thousand meters. The density and scale were so high that they far exceeded the previous two lines of defense!

The first group of more than 20 Japanese planes that plunged into the death trap looked at the rays of light approaching from the ground diagonally below. As soon as they made an evasive maneuver, they were beaten like a hornet's nest by the roaring steel balls and fragments!
Chapter completed!
