Just when the heavy artillery units on both sides were opening up their positions and preparing to launch fierce artillery strikes on each other, Qiao Youhua, Jiang Haidong, and Ma Biao piloted three fighter planes to arrive over the Shanhaiguan battlefield first.

Without the slightest hesitation, under the leadership of Qiao Youhua, the three fighters swooped down at high speed towards the Japanese defenders on the north pass of Shanhaiguan in a sharp formation, and after entering the firing range, all the machine guns and aerial guns on the three fighters opened fire one after another.

With more and more devil reinforcements on the north pass, the crowd was already very dense, and suddenly it was strafed by intensive dive fire, and the devils suddenly suffered a large increase in casualties, and they fell down one by one.

"Yaga, it's the plane of the China, damn it! Here they are again! "There were ghost soldiers who had fled from Nanguan in the chaotic army, and they immediately let out a frightened wail and curse.

They had experienced the battle for Nanguan, and they were beaten badly by these small but extremely hated Chinese fighters.

Some extremely angry devil machine gunners even picked up light machine guns and began to fire wildly into the air, trying to shoot down the fighter plane piloted by Qiao Youhua and the three of them.

However, before the Devil Heavy who stood up could fire a few bullets, he was hit by the fire of the Dragon's Tooth Attack Force under the wall because of the increase in body violence, and he fell down on the spot, and the crooked machine gun in his hand also fell far away, smashing into a Devil Rifleman who was lying behind the battlement wall and shooting, knocking him unconscious.

Qiao Youhua and the three piloted the fighter plane to fire fiercely, flying quickly over the devil's head, and just as they were about to turn back and continue to strafe the Japanese army crowd at the head of the city, Ma Biao and Jiang Haidong both discovered something in vain that surprised them.

"Dragon King, look at the ground outside the gate!"

"Oh no, it looks like it's a heavy artillery! Good boy! Ma Biao and Jiang Haidong spoke out one after another.

When Qiao Youhua heard this, he immediately piloted the fighter plane to reduce the flight altitude and flew towards the suspicious target group, and Ma Biao and Jiang Haidong also hurriedly drove the fighter plane to follow him.

As the altitude decreased, they finally saw the target clearly, and yes, it was the heavy artillery position of the devils.

Looking at the giant cannon that was much larger than his own 105mm howitzer, Qiao Youhua and the three of them couldn't help but take a breath of cold air, fortunately they accidentally discovered the devil's heavy artillery position, otherwise the advance corps that was storming the Japanese defense line in the pass would probably suffer a big loss.

The caliber of this kind of artillery should be at least 150mm or more, let alone hundreds of guns, even if there are only ten, it is enough to cover the narrow area in Shanhaiguan and deal a devastating blow to any living force in the pass.

This thing weighs dozens of kilograms in a shell, and when it explodes, it is at least an absolute killing range of 50 meters.

If the invincible No. 4 tank is hit by a shot, I am afraid that it will also be blown into a pile of scrap metal, or it will be thrown away.

Not to mention the light infantry who served as assistants, the fate is conceivable.

"Head, what are we going to do?" Jiang Haidong asked anxiously.

"What else can I do, blow up his son of a bitch." Ma Biao interjected without thinking.

"What to fry? Don't forget, we're all fighters this time! Jiang Haidong said.

"So what to do? We can't let the little devils really shoot at our army in the pass, if that happens, the advance corps will suffer a big loss. Ma Biao was also anxious.

Qiao Youhua pondered for a while, and said resolutely: "Dive and strafe immediately, and hit me hard with a machine gun!" At all costs, it is necessary to stop the devil's heavy artillery troops from firing at the pass. In addition, tell Liu Jianhua about the situation immediately, and let them immediately increase their attack and capture the city wall of Shanhaiguan Beiguan as soon as possible.

In the field, what will the devils do to resist the swarm charge of our tank armor? At that time, the devil's heavy artillery unit will become a pile of useless scrap metal! ”

"We concentrate our firepower and specialize in shooting heavy artillery and ammunition piles for devils!" Qiao Youhua added.

"Yes! Got it! Jiang Haidong and Ma Biao both readily agreed, even if it was very dangerous to stay, Qiao Youhua would never have any objections to the decision, without hesitation, life and death together, this is the unique tacit friendship between their brothers.

The three fighters immediately accelerated and dived towards the ground, all their firepower was in full swing in an instant, and a dense rain of bullets poured towards the Devil's heavy artillery position.

The devil artillery who was urgently building a heavy artillery position, although the baggage soldiers had already seen these three uninvited guests, but without an order, coupled with the duty of the heavy artillery, they could not leave their posts without permission, so under the dive fire of Qiao Youhua and others, they all fell down screaming.

Sudden ...... Tongues of scorching fire whipped down from the sky, and everywhere they went, smoke and dust rose everywhere, sparks flew everywhere, and the devils were shot and fell down.

Some people were shot in the waist, and they were broken off by the beating, and their bodies were cut in two, and some people were shot in the chest, and when they landed on the chest, there was a bloody hole the size of a watermelon, and the hot blood gushed out everywhere, which was extremely tragic.

There are even devils who were shot in the head and directly turned into headless corpses, and in a moment, Qiao Youhua and they had already strafed back and forth twice, shooting at least dozens of devil artillery and a large number of baggage soldiers and automobile soldiers who helped set up artillery.

The reason why there are so many auxiliary units is because the Devil's 150mm heavy gun is very large and heavy, and it must be towed by truck or transported by train.

Every time they fight, they need a long time to get these big guys off the car or train, pull them to the predetermined artillery position, and start all kinds of preparations such as framing.

The 12th Division's heavy artillery brigade has seven or eight thousand combat personnel and more than 3,000 auxiliary troops.

Upon discovering that Qiao Youhua and the others were driving fighter planes to attack the air, the guards of the Devil's Heavy Artillery Unit were taken aback, and many officers and men of the garrison raised their guns in a panic to shoot at the air, but they could not hit the target at all.

With their superb flying skills, Qiao Youhua and the three of them piloted the fighter plane to use various evasion maneuvers, while dodging the blows of the devil's ground fire, they continued to dive and strafe, focusing on the devil's artillery and mountains of ammunition boxes.

Soon a bunch of ammunition boxes filled with high-explosive grenades were hit by shells from a twenty-mm machine gun, and suddenly there was a fire and a violent explosion occurred.

The violent explosion was like an earthquake, and the devil soldiers within a radius of 100 meters were overturned and blown away, and where the shock wave passed, the devil artillery position was a mess, with dead bodies everywhere, and all kinds of stumps and broken arms flew everywhere.

There was a devil's head that fell on the body of a huge 150mm heavy cannon, and his eyes were still open, obviously dead.
