A magazine of 30,000 rounds, you call it Hanyang

"The Japs are causing quite a big fuss. They've even sent out bombers."

Zheng Kaixuan had some knowledge about the Japanese fighter planes during World War II. Just from the sound the plane made, he could roughly tell what kind of plane was coming.

Generally speaking, bombers are relatively large and equipped with particularly powerful engines, and the sound they make when flying is relatively heavy and low.

As for fighter jets, their engines are slightly smaller, so the sound they make is sharper and higher-pitched.

In addition, fighter jets have fast flying speeds and high maneuverability. The sound frequency they make during flight is also relatively high, and the noise is particularly loud.

Judging from the sounds in the sky, the Japanese have dispatched a total of two fighter planes and one bomber this time, which can be considered a small combat formation.

Normally, on the battlefields of other countries, fighter jets will not be sent to carry out bombing missions unless necessary.

The advantages of fighter jets are mainly their high speed and high maneuverability and flexibility, and they are usually used in air combat against enemy aircraft.

But there was an exception on the Chinese battlefield.

Many times, the Japanese fighter planes would be sent out to carry out bombing missions because of their fast speed and ease of deployment.

The Japanese fighter planes were designed with bomb carrying in mind. They were equipped with bomb racks underneath that could carry a variety of bombs of varying sizes and weights.

It can perform a variety of tasks including air-to-air and ground-to-ground bombing.

Although carrying bombs on fighter planes would greatly affect their flexibility, the Japanese did not take this issue seriously at all and did not take it to heart at all.

The main reason was that at that time China’s air power was almost completely lost, leaving the country without defense.

The Japanese had almost no opponents in the air and could fly with impunity.

On the ground, especially in the Shanxi region, there are almost no effective air defense weapons.

Many times, when forced into a desperate situation, guerrillas in various places would use machine guns and other weapons to shoot into the air, but the possibility of causing damage to the Japanese fighter planes was too small.

Zheng Kaixuan originally thought that the Japanese sent only fighter jets to carry out the bombing.

Even he didn't expect that the Japanese would send out bombers this time.

The cost of a bomber is more than ten times higher than that of a fighter jet. If the Japanese bomber is shot down, the Japanese will suffer huge losses.

That's what I thought, but the Japanese bombers are not that easy to defeat.

Even with the Triumph anti-aircraft machine gun, Zheng Kaixuan was not absolutely sure.

If a bomber is dropping bombs at high altitude, it can be done at an altitude of more than 5000 meters.

It can be said that at this altitude, Zheng Kaixuan might not even be able to see the shadow of the Japanese bomber, let alone a precise strike.

If the Japanese bombers dropped bombs at medium altitude, their flight altitude would be between 2000 and 5000 meters, and the probability of being hit would not be too high.

"Buzzing..."

The roar of fighter planes continued to echo in the air, but the sound of explosions did not occur.

The Japanese fighter planes kept circling in the air, and no one knew what they were planning.

Zheng Kaixuan personally held the firing button of the anti-aircraft machine gun and did not dare to act rashly.

Xin Qiankun and others kept Zheng Kaixuan's instructions in mind. No one dared to show their heads and they all lay down in the tunnel.

However, the covers of the tunnel exits are slightly open to make it easier to hear the sounds outside.

"Om..."

The sound of the plane breaking through the air was getting closer and louder.

A Japanese fighter plane finally couldn't help it and dived at low altitude.

Wei Zhuang has a special geographical location, with its back against the mountains and facing the Heiyunkou Canyon.

This village is the largest within a radius of one kilometer, and it is far away from other villages, making it very easy to identify.

A Japanese fighter plane swooped down from a high altitude.

3000 meters, 2500 meters, 2000 meters, in the blink of an eye, it was within 1500 meters.

This distance is actually completely within the coverage range of the Triumph anti-aircraft machine gun.

"Captain, do you want to fight or not?"

A soldier next to Zheng Kaixuan quickly turned the turntable to aim the anti-aircraft machine gun at the Japanese fighter plane.

"Take your time, wait a moment."

The development of the matter was exactly as Zheng Kaixuan had expected.

The Japs are testing us!

In fact, many of the Japanese special forces are very rigorous when performing their tasks.

Especially this time they have to face the spearhead regiment that has covered the Japanese positions with firepower many times during battles.

This Japanese fighter plane flew at low altitude for two main purposes.

First, he wanted to see whether the spearhead regiment's artillery could provide air defense and pose a threat to combat units.

Secondly, of course, we need to confirm whether there is anyone in Wei Zhuang and whether the members of the Sharp Knife Group are still there.

If the members of the Sharp Knife Regiment were not in Wei Zhuang at all, then their bombing would have been in vain and meaningless.

The bombers will only take action after confirming that there are people in the village.

In the blink of an eye, the Japanese fighter plane's flying altitude had reached about 500 meters.

Below 500 meters is considered ultra-low altitude flight for fighter jets.

"Come out, Tubalu."

The Japanese pilot sneered and then began to drop bombs.

"Boom! Boom! Boom! Boom!"

This Japanese fighter plane was carrying a total of four 30kg aerial bombs.

The accuracy of low-altitude bombing is relatively high. Four bombs were dropped one after another on several relatively tall houses in the village.

As the explosions rang out, the houses were blown into pieces and collapsed.

"Whoosh..."

Immediately, the Japanese fighter plane climbed to a height of eight or nine hundred meters above the ground, circling back and forth and beginning to observe the movements in the village.

At this moment, Xin Qiankun and others took action.

Ten soldiers from the spearhead regiment quickly climbed out of the tunnel, holding weapons, and simultaneously launched an attack on the Japanese fighter planes in the sky from four or five locations in the village.

"Boom! Boom! Boom!"

In just a short moment, Xin Qiankun and a soldier fired three mortar shells into the sky.

However, the shells deviated too far from the target and did not even touch the Japanese fighter plane. They did not even reach an altitude of 500 meters and fell along a parabola into the ravine behind the village.

The same situation occurred with the other mortars, which did not cause any damage to the Japanese fighter planes.

"Da da da da..."

At the same time, the Pheasant Neck heavy machine gun also opened fire.

This heavy machine gun is quite powerful when shooting on flat ground with the help of a tripod, but it is more difficult to shoot into the air.

It takes a warrior to pick it up.

Holding a lump of iron weighing dozens of pounds in my arms, the recoil when shooting was so strong that I couldn't hold it at all, let alone maintain stability.

With the cooperation of two or three soldiers, they were able to barely use the machine gun to fire dozens of bullets into the air.

Of course, there was no accuracy at all. Because of the recoil, the bullets were like drawing a map and did not touch the Japanese fighter planes at all.

Immediately, the soldiers of the spearhead regiment threw away their weapons, rolled over and jumped into the tunnel, hiding deep in the tunnel.

Next, they don’t have to worry about anything else and just leave it to Zheng Kaixuan.
