If you get closer, you will notice that the bomb seems to be bigger than a normal rocket. And it looks more like the kind of giant rockets used in rocket carts.

A large number of workers began to bring out cattle, sheep and other animals and send them into the shooting range in carts. A large white circle had already been preset at the shooting range.

There is a piece of fortification built in this circle. The construction materials of these fortifications are all the building materials and building dimensions and thicknesses of the Japanese troops on the first and second line positions. Even compared to the fortifications of the Japanese army in Shanghai, in terms of thickness and solidity.

The cattle and sheep were led and tied to these fortifications, and then the staff quickly evacuated.

Jia Xiaohou's nervous palms began to sweat, and he watched as the huge rocket-shaped weapon was mounted on the tiger moth with tools. At this time, it was obvious that this rocket was obviously much larger than that used by the Wehrmacht in the past. So big that even a tiger moth can only be mounted with one such weapon.

"Buzz...... Woo~~" With the roar of the engine, the tiger moth flew into the sky at once. After circling for a while, swoop down! The rocket was dropped at a large white circle on the range.

Note! The rockets were not fired directly, but were dropped from a high altitude. The rocket was dropped head-down, and when the bomb was dropped, the plane pulled up and quickly moved away from the rocket

Then I saw that the rocket descended to a certain extent, that is, after the plane left the rocket for a certain distance, it began to ignite on its own, with the power of the dive and the thrust of the rocket, rushing towards the bullseye of the white circle!

As the flames of the "whirring ......" continued to erupt, the rocket gradually rushed towards the white circle on the shooting range below. The speed of the rocket coming down from a high altitude, combined with the propulsion of the rocket, made the entire rocket reach an incredible speed.

"Boom!!" Then, I saw the rocket slam into the white circle at a frantic speed. Suddenly, a dazzling light erupted in the entire white circle.

Subsequently. In the rumbling explosion, a huge mushroom cloud visible to the naked eye slowly rose from within the white circle. The white lines of the white circle were no longer visible, and everywhere there was flying dust and smoke and broken concrete blocks.

The rumbling explosion slowly dissipated after a while. And Jia Xiaohou couldn't wait to board the car and rush towards the explosion point of the shooting range.

Along the way, Shen Hong and the other researchers looked at the concrete blocks and steel bars that were blown dozens of meters away, and swallowed saliva, although this terrifying weapon was built by them, but the calculation and actual seeing were not the same concept at all.

They even saw a shattered fragment of a sheep's head that had been blown up beyond recognition. The head of the sheep could no longer be seen to have belonged to a sheep, except for a small half-pulled white skull with a small horn on it.

There is not the slightest trace of gore to be seen along the way, but this kind of power that cannot even be seen in blood is even more terrifying.

Finally. After more than ten minutes of running, everyone came to this bull's-eye. Jia Xiaohou and the others jumped out of the car, and Shen Hong and the others began to take people to calculate the results of these explosions.

"Goo~" Although the result has been guessed from the calculation, everyone is still shocked to see a deep pit with a diameter of six meters and a depth of seven or eight meters!

It's not like other weapons tests, there's really not a trace of gore here. Not even the corpses in fragments were to be seen. Everyone carefully took out the tape measure and began to measure the deep pit that appeared in the shooting range.

There were some broken pieces of concrete left in the pit. And there is no trace of fortification in the pit. Only the broken pieces of concrete, silently telling what had happened here.

The reinforced concrete fortifications, built five meters underground, are now long gone. The cattle and sheep that were tied up in the fortifications were all gone.

Jia Xiaohou and Shen Hong began to lead people into the pit after everyone had made a rough measurement. The power of a bomb is judged by the degree of damage caused by the explosion.

Since the front-line positions reported back the Japanese fortifications, Jia Xiaohou's new task was to study how to use bombs and rockets to break the Japanese fortifications from the air.

At present, the greatest advantage of the Wehrmacht is the Air Force, and the airspace of the entire Shanghai and even the mainland belongs to the Wehrmacht. How can you take advantage of that. Breaking down the Japanese fortifications from the air became the top priority of the study.

The first to be studied was the bomb. At present, the Wehrmacht has the largest payload capacity, and it is the Tiger Moth multi-role fighter. If all the weapons are dropped, the Tiger Moth can carry up to two tons.

As a result, the tiger moth became the preferred bomb throwing tool. But as the research deepened. Jia Xiaohou and others found that even if the tiger moth used a ton of explosives, there would be many problems in bombing the Japanese fortifications.

The first is the issue of accuracy. The bombing bombs were uncontrollable in terms of accuracy, and at most they could be controlled within 60 meters. This is already the limit of pilots.

The second is the power of the bomb. After testing, Jia Xiaohou and others found that there was no way to penetrate the Japanese fortifications by bombing with high-explosive charges. Although the shock wave will kill and injure the Japanese troops inside, the inaccurate bomb can only rely on luck to hit the Japanese fortifications.

And the lack of penetration power of the bomb is also a huge problem. If there were no destroyed Japanese fortifications, then the Japanese could have sent people to garrison again after the bombing.

When Jia Xiaohou was at a loss, his apprentice Shen Hong put forward a bold idea: to use armor-piercing shells to make rockets!

Aimed projectiles are carried out at medium and low altitudes. Then the firing is delayed. Using the speed of descent combined with the power of the rocket launch, the rocket was propelled to directly impact the Japanese fortifications.

The armor-piercing shell's alloy steel armor-piercing body thickened the front end and plunged directly into the dirt under the impetus of a powerful descent speed and rocket power. The rocket was then detonated with a delayed fuse, which was propelled by high-performance explosives and detonated into the fortifications.

But obviously, neither Jia Xiaohou nor Shen Hong, the author of the idea, thought that the power of this weapon made by them was beyond their imagination.

The alloy steel armor-piercing body pierced, and the enormous power of the impact and the power of the explosion exceeded their calculations. Under the great force, the fortifications were completely destroyed. The reinforced concrete fortifications, built five meters underground, were destroyed by a single blow.

"Teacher, are we going to tell the commander-in-chief about the results of the test?!" Some time ago, knowing that the Fifth Army had stormed the Japanese positions and brought heavy casualties, the entire research institute was heartbroken.

Under this stimulus, they stepped up the speed of research and development. In the past two months, 200 tests have been made. Finally came up with a solution.

"No hurry! Let's do a couple of more experiments first. Jia Xiaohou waved his hand and said, "These weapons are related to the lives of the soldiers!" We must not be sloppy, we are not absolutely sure that we will not allow it to go to war. ”

Shen Hong nodded, he was also in a hurry. The Sixth Army had been trapped in the third-line position for more than a week, and according to intelligence, Japanese support had arrived in Shanghai.

In other words, the next battles will be even more difficult to fight. Shen Hong thought about how to equip these weapons to the front-line troops as soon as possible.

A series of calculations have been completed, and the site has been cordoned off. Jia Xiaohou took Shen Hong and others to devote themselves to research again.

The factory is very fast, and in fact, several sets of these rocket-booster bombs have already been built. When the instructions of the institute were obtained. The workshop then began to assemble.

It was another busy night, until ten o'clock in the morning, Jia Xiaohou and the researchers hurriedly ate some green onion cakes with strong tea and rushed to the test site.

In order to cooperate with Jia Xiaohou's experiment, the sappers built more than a dozen such test fortifications as early as the beginning of bomb development. Later, as the experiment progressed, these fortifications continued to increase.

Until now, there are more than 20 of them! It's enough for Jia Xiaohou to toss them. And the Air Force assistant pilots were already on standby at the airport early.

This proving ground, which cost the Wehrmacht enormous financial, manpower and physical resources, is not only very large. And all kinds of facilities are complete. From the fortifications on the hilltops, to the airport, the processing plant and the wind tunnel...... And so on, you name it.

"Boom!!" The test continued, and the sound of explosions continued to sound from the white circles on the mountain. The bones of the cattle and sheep are still gone.

At this time, the port of Shanghai is busy. After making a compromise, the Japanese Navy moved quickly. The Japanese Navy mobilized its own freighters, warships, etc., and began to send supplies to Shanghai.

Shunroku Hata was not punished after all. After all, he still has a lot of people in the base camp to help speak, including Ishihara Wan'er, the most important prince of the Idle Palace.

Moreover, the Battle of Shanghai has been fought so far, and all the positions of the fifth line and the third line are in the hands of the Japanese army, which has exceeded the expectations of the base camp. Originally, in the opinion of the base camp, it was able to hold the fourth-line position at this time. Even if it's a meritorious service.

Even Matsui Ishone, who was assigned to the reserve, pleaded with the base camp for Shunroku Hata through various channels. In his opinion, Shunroku Hata has indeed done his duty.

Even if it is a different person, he may not be able to do as well as Shunroku Hatata. It is quite possible that even the fourth-line positions will not be maintained.

"General. Let me tell you that you don't have to lose faith. As long as you hold on, reinforcements will arrive soon. Shigetaro Shimada, the Japanese admiral in charge of this transportation mission, looked at the haggard Shunroku Hata and sighed helplessly.

"We all know your difficulties in China. But for the sake of the empire. Please stick with it. I believe that it will be our Empire Japan that will be able to achieve the ultimate victory! ”

Shunroku Hata nodded. His face was pale, and there was not a trace of blood in sight. The experience of this period of time has made him haggard. The aggressiveness of the Wehrmacht and the urgency of the war situation made it difficult for him to sleep.

He is also aware of the domestic debate over whether to withdraw troops from China. He didn't say much on this issue. Emotionally, Shunroku Hata did not want to withdraw from China.

But he also had to agree with the Navy that the war in China was only a drain on Japan's strength. There will be no benefit. Unless the Japanese are able to completely defeat the Wehrmacht, everything that appears to be an advantage will eventually turn into a disadvantage.

"The air fleet is not here yet, and the new aircraft needs more tests before it can be mass-produced." Shimada saw that Shunroku Hata seemed reluctant to say anything, so he changed the subject.

Shunroku Hatata's pale face turned a little whiter when he heard this. During this time, the Wehrmacht bombardment never stopped, and Shunroku Hata felt that his position seemed to have become a testing ground for the Wehrmacht's bombing.

The casualties on the positions were increasing, and even the surviving Japanese soldiers became extremely strange. Many people have all kinds of physical problems, from tinnitus to injuries to internal organs.

"Ahem...... When will our air fleet be able to arrive?! Shunroku Hata coughed for a while before he reluctantly said such a sentence.

Shimada looked at Shunroku Hatata. "It will take at least half a month." You know, it will take time for an aircraft to go from trial to mass production. Although the prototype is now out, there is always a transition for the factory to start coordinating production......"

Shunroku Hata smiled bitterly and stopped talking, looking at the rumbling position in the distance that was shaken by the sound of artillery without saying a word.

Suddenly, there was a roar of "buzzing ......" in the sky. A terrible air defense siren sounded on the pier, and the planes on the aircraft carriers escorting the fleet began to take off to meet the enemy.

The transport on the ground was all diverted to the nearest bomb shelter. Shunroku Hahata and Shimada naturally had someone lead the way to the bomb shelter to avoid the air raid.

And the Japanese warships in the harbor also began to anchor, and the sailors on the warships began to enter combat positions. Anti-aircraft machine guns, anti-aircraft guns began to open and reload.

One after another, Japanese fighters rose from the aircraft carrier and flew towards the outer positions.

The aircraft carrier escorted this time was the Kaga, which had more than 70 carrier-based aircraft on board. Although there was a certain intention to assist the Shanghai defenders. But Shimada never thought of going into battle before he finished unloading.

"Woo~~Tutu ......" The Wehrmacht aircraft group in the sky obviously did not expect to encounter Japanese fighters, but the appearance of Japanese fighters made them even more excited.

During this time, they have been carrying out bombing missions and strafing ground targets, and everyone is already tired. Now that there is finally a group of opponents who can fight with them, how does this make these warhawks unhappy?!

"Woo~~~" But these Japanese planes were obviously unusual, and they roared and made a sharp turn to avoid the sudden encirclement and suppression of the Wehrmacht warhawks. This surprised the Wehrmacht warhawks.

But then they adjusted. The tactics of the Wehrmacht Air Force were never doggling. Instead, they constantly pulled up the fighters and then annihilated the opponent with heavy fire with a dive.

At this point, the war eagles in the sky played very well.

"Tutu Tu Tu ...... Rumble!! "A Japanese fighter plane was swept away by a 20mm cannon and suddenly turned into a fireball and fell from the sky.

The other Japanese fighters began to try to encircle the Wehrmacht Tiger Shark, but they didn't notice that the other Tiger Sharks above their heads had opened their mouths.

"Red deer! Watch the top of your head! Watch the top of your head!! The Japanese captain who discovered the Wehrmacht's movements kept shouting with blood-red eyes, but unfortunately the Japanese communication equipment was so bad that these warnings could not be transmitted at all.

"Tutu Tu Tu ...... Rumble!! "Even if the Wehrmacht doesn't have a 20mm cannon, its on-board machine gun is not vegetarian. The Japanese army's thin fuselage could not stop the bullets at all.

As long as it was hit, it would explode into a cloud of sparks, but the Japanese had enough of them in their fleet. More than 60 warplanes were lifted into the air. Tiger sharks trying to encircle the Wehrmacht.

At this time, the air defense siren of the Wehrmacht Air Force airfield in Kunshan was also sounding violently. The Wehrmacht warhawks who were preparing for the war quickly began to change their outfits and board the plane.

On-board machine gun ammunition, cannon ammunition...... and so on were all mounted on the tiger shark, and then suddenly rose from the ground under the command of the ground crew! Kill in the sky above Shanghai!

Obviously, neither the Wehrmacht nor the Japanese expected to suddenly encounter each other here. The battle was fought in great haste. But whether it is the Japanese army or the warhawks of the Wehrmacht. All have rich practical experience.

Therefore, all the equipment is prepared in advance, and it can be immediately lifted into the air when it is mounted on the plane.

The Tiger Moth that carried out the bombing mission had already withdrawn when the Japanese fighters took off, and now it was the Tiger Shark A interceptor that took off to meet the enemy.

"Tutu Tu Tu ...... Bang! "Eventually, the Wehrmacht Warhawks, who were outnumbered by the Japanese siege, began to suffer casualties. Japanese fighters continued to use their flexibility to encircle and suppress the Wehrmacht's warhawks.

The Wehrmacht's eagles were constantly pulling up to avoid Japanese attacks. The battle in the sky was heated at the beginning. The fighting between the two sides became more and more fierce.

Constantly the tiger sharks of the Wehrmacht were beaten and fell obliquely with black smoke, and there were also Japanese fighters that were beaten into a ball of sparks and burst out of the sky.

But these Wehrmacht warhawks did not back down. They were constantly fighting against twice as many Japanese troops. By this time, six Wehrmacht Tiger Sharks had already been shot down.

Of course, the Japanese army could not stand it well. Eight Type Zero and four Type 97 carrier-based aircraft, this is the price paid by the Japanese army. And as the sky fought, the artillery on the ground also began to shell the Japanese positions.

In the roaring artillery, the Japanese troops on the position could only cower in their own fortifications. Most of the downed tiger sharks chose to get out of the battlefield as much as possible and make a forced landing on their own positions.

The few two planes were forced to land in the middle of the positions of the Japanese and the Wehrmacht, and the Japanese troops who saw the positions of these fighters suddenly appeared! Their purpose was simple: to seize these fighters and send them back to China for study.

"Grandma's! Not a single screw of these planes can be taken away by the screw!! Ren Wenbin, the commander of the Sixth Army, roared in his headquarters: "Grab it back with Lao Tzu!" ”

ps: This chapter is very tangled...... I checked a lot of information~ It's finally done......
