If you get closer, you will find that this bomb seems to be larger than ordinary rockets. And it looks more like the huge rockets used on rocket launchers.

A large number of staff began to pull out cattle, sheep and other animals and drive them into the shooting range in vehicles. A large white circle had already been preset at the shooting range.

A large number of fortifications are being built in this circle. The construction materials of these fortifications are all the building materials, construction dimensions and thickness of the Japanese army on the first and second line positions. They are even better than those of the Japanese army in Shanghai in terms of thickness and sturdiness.

Nothing less.

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

Jia Xiaohou's nervous palms began to sweat. He watched the huge rocket-shaped weapon being mounted on the tiger head moth with tools. At this time, it was obvious that this rocket was obviously better than the one used by the National Defense Forces in the past.

The ones are much bigger. So big that even the Tiger-headed Moth can only mount one such weapon.

"Buzz buzz... Woo~~" With the roar of the engine, the Tiger Head Moth suddenly flew into the sky. After hovering for a while, it suddenly dived! It dropped hard towards a huge white circle on the shooting range.

Got this rocket.

Attention! This rocket was not fired directly, but dropped from a high altitude. When the rocket was dropped, the head was facing down. After the bomb was dropped, the plane suddenly pulled up and quickly left the rocket.

Then I saw that the rocket had dropped to a certain level, and the aircraft started to ignite itself after being some distance away from the rocket, rushing towards the bullseye in the white circle with the power of dive and the boost of the rocket!

As the "whoosh..." flames continued to spurt, the rocket gradually rushed towards the white circle on the shooting range below. The speed of rushing down from high altitude, coupled with the propulsion of the rocket, made the speed of the entire rocket reach an incredible level.

.

"Boom!!" Then, the rocket suddenly crashed into the white circle at a crazy speed. Suddenly, the entire white circle burst out with dazzling light.

Then, amidst the rumbling explosion, a huge mushroom cloud visible to the naked eye slowly rose from the white circle. The white line of the white circle was no longer visible, and there was dust and smoke flying everywhere.

and broken concrete blocks.

The rumbling explosion slowly dissipated after a while. Jia Xiaohou could not wait to get in the car and rush towards the explosion point at the shooting range.

Along the way, Shen Hong and other researchers couldn't help but swallow their saliva as they looked at the concrete blocks and steel bars that were blown dozens of meters away. Although they made this terrifying weapon, calculations and actual sightings are completely different concepts.

They even saw the remains of a sheep's head that had been bombed beyond recognition and broken into pieces. It was no longer clear that the sheep's head once belonged to a sheep. Only a small section of the pale skull with a small section of horns was left.

.

There was no trace of blood along the way, but this power without even blood was even more frightening.

Finally, after more than ten minutes of running around, everyone arrived at the bullseye. Jia Xiaohou and others jumped out of the car, and Shen Hong and others began to lead people to calculate the results of these explosions.

"Gudu~" Although they had already guessed the result from the calculation, everyone was still shocked to see a pit with a diameter of six meters and a depth of seven or eight meters with their own eyes!

Unlike other weapons tests, there was really not even a trace of blood here. Not even broken corpses could be seen. Everyone carefully took out the measuring tape and began to measure the deep pit that appeared in the shooting range.

There are some broken concrete fragments left in the deep pit. There is no trace of any fortifications in the pit. Only the broken concrete fragments silently tell what happened here.

The reinforced concrete fortifications built five meters underground have long since disappeared. The cattle and sheep tied up in the fortifications have also disappeared.

After everyone made rough measurements, Jia Xiaohou and Shen Hong began to lead people into the pit. The power of the bomb was judged by the degree of damage caused by the explosion.

After reporting back the Japanese fortifications from the front line, Jia Xiaohou and the others' new task was to study how to use bombs and rockets to destroy the Japanese fortifications from the air.

Now the biggest advantage of the National Defense Force is the air force. The airspace of the entire Shanghai and even the mainland belongs to the National Defense Force. How to use this advantage to defeat the Japanese fortifications from the air has become the top priority of research.

The first thing to be studied is bombs. Currently, the largest load capacity of the National Defense Force is the Tiger Moth multi-purpose fighter. If all weapons are removed, the Tiger Moth can carry two tons.

Therefore, the tiger-headed moth became the preferred bomb-throwing tool. However, as the research deepened, Jia Xiaohou and others found that even if the tiger-headed moth used one ton of explosives to bomb the Japanese fortifications, there would be many problems.

The first is the issue of accuracy. It is difficult to control the accuracy of the bombs dropped. At most, they can be controlled within sixty meters. This is already the limit of the pilot.

The second is the power of the bomb. After testing, Jia Xiaohou and others found that it was impossible to penetrate the Japanese fortifications simply by bombing with high-explosive weapons. Although the shock wave would kill the Japanese troops inside, without precision bombs they could only rely on

Try your luck to hit the Japanese fortifications.

The lack of penetration power of the bomb is also a huge problem. If the Japanese fortifications were not destroyed, then the Japanese army could send people to garrison again after the bombing.

When Jia Xiaohou was at a loss, his apprentice Shen Hong came up with a bold idea: use armor-piercing bullets to make rockets!

Aim and projectile at medium and low altitudes. Then delay the firing. Use the speed of descent plus the power of rocket launch to push the rocket to directly impact the Japanese fortifications.

The alloy steel armor-piercing body of the armor-piercing projectile has a thickened front end, and it rushes directly into the soil driven by the strong descending speed and rocket power. Then the delayed fuse detonates the rocket, and it rushes into the ground driven by the high-performance missile.

The fortifications exploded.

But obviously, neither Jia Xiaohou nor Shen Hong, the person who proposed the idea, thought that the power of the weapon they produced was beyond their imagination.

The alloy steel armor-piercing body penetrated, and the huge power of the impact and the power of the explosion exceeded their calculations. Under the huge power, the fortification was completely destroyed. The reinforced concrete fortification built five meters underground was destroyed by one blow.

Then it was reduced to ashes.

"Teacher, should we tell the Commander-in-Chief the results of the test?!" Some time ago, the entire institute was heartbroken after learning that the Fifth Army's storming of the Japanese positions had caused heavy casualties.

Under this stimulation, they accelerated their research and development. They tested it more than 200 times in the past two months and finally came up with a solution.

"No rush! Let's do a few more tests first." Jia Xiaohou waved his hand and said: "These weapons are related to the lives of the soldiers! We can't be careless. We don't have absolute certainty that we can't let them go on the battlefield."

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

In other words, the next battle will be more difficult to fight. What Shen Hong wants is how to equip these weapons to the frontline troops as soon as possible.

A series of calculations have been completed and the site has been sealed off. Jia Xiaohou, Shen Hong and others once again devoted themselves to the research.

The factory was manufacturing very quickly. In fact, several sets of these rocket-propelled bombs had already been built. After receiving instructions from the research institute, the workshop began to assemble them.

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

In order to cooperate with Jia Xiaohou's experiments, engineers and soldiers built more than a dozen such test fortifications as early as the beginning of bomb research and development. Later, as the tests progressed, these fortifications continued to increase.

Until now, there are more than twenty seats! It is enough for Jia Xiaohou and others. And the assisting pilots of the Air Force have been on standby at the airport early.

This test site, which cost the National Defense Forces huge financial, manpower and physical resources to build, not only occupies a huge area, but also has various facilities. From mountain fortifications to airports, processing plants and wind tunnels... everything is available.

"Boom!!" The experiment continued, and explosions continued to sound from the white circle on the mountain. There were still no bones of the cattle and sheep.

At this time, the Shanghai port was busy. After making a compromise, the Japanese Navy moved quickly. The Japanese Navy mobilized its own cargo ships, warships, etc. to begin transporting supplies to Shanghai.

After all, Hata Shunroku was not punished. After all, he still had many people at the base camp to help him speak up. These people included Kanji Ishihara, who was most valued by Prince Kanin Palace Zaihito.

Moreover, the Battle of Shanghai has reached this point. All the five-front positions and the third front are in the hands of the Japanese army. This has exceeded the expectations of the base camp. Originally, from the base camp's point of view, being able to hold on to the fourth-line position at this time is considered a meritorious service.

Even Matsui Iwane, who was assigned to the reserve force, used various channels to plead with the base camp for Hata Shunroku. In his opinion, Hata Shunroku had indeed fulfilled his duty.

Even if it were another person, he might not be able to do as well as Shunroku Hata. He might even not be able to defend the fourth-line position.

"General, His Majesty Kanin Palace, please let me tell you: There is no need to lose confidence. As long as you persist, reinforcements will arrive soon." Japanese Navy Admiral Shitaro Shimada, who was in charge of this transportation mission, looked at the haggard Shunroku Hata, helplessly. Sighed.

"We are all aware of your difficulties in China. But for the sake of the empire, please persevere. I believe that the one who can win the final victory will definitely be our Empire of Japan!"

Shunroku Hata nodded. His face was so pale that no trace of blood could be seen. The experience during this period had made him mentally and physically exhausted. The aggressiveness of the National Defense Forces and the critical nature of the war situation made it difficult for him to sleep or eat well.

He is also aware of the domestic debate on whether to withdraw troops from China. On this issue, he is not good at saying too much. Emotionally speaking, Shunroku Hata does not want to withdraw from China.

But he also had to agree with the Navy's view that fighting in China would only consume Japan's power and would not achieve any benefits. Unless the Japanese army could completely defeat the National Defense Forces, everything that seemed to be advantages would eventually turn into disadvantages.

"The air force cannot come yet, and the new aircraft needs more tests before it can be mass-produced." Shimada Mihata Shunroku seemed unwilling to say anything more, so he changed the topic.

Shunroku Hata's pale face turned a little paler after hearing these words. During this period, the bombing of the National Defense Forces has not stopped, and Shunroku Hata felt that his position seemed to have become a testing ground for the bombing of the National Defense Forces.

The casualties on the battlefield were increasing, and even the surviving Japanese soldiers became extremely weird. Many of them suffered from various physical problems, ranging from tinnitus to injuries to their internal organs.

"Ahem...when will our air force arrive?!" Shunroku Hata reluctantly said this after coughing for a while.

Shimada looked at Shunroku Hata and said: "It will take at least half a month. You know, it will take time for the aircraft to go from testing to mass production. Although the prototype has been released now, there will always be a transition before the factory starts to coordinate production..."

Shunroku Hata smiled bitterly and stopped talking. He looked at the rumbling position in the distance that was shaken by the sound of artillery and said nothing.

Suddenly, a roar of "buzz, buzz..." came from the sky. A shrill air defense siren sounded on the dock, and the aircraft on the aircraft carrier escorting the fleet began to take off to meet the enemy.

All transportation on the ground was moved towards the nearest air-raid shelter. Naturally, Shunroku Hata and Shimada had people leading the way to the air-raid shelter to avoid air raids.

The Japanese warships in the port also began to weigh anchor, and the sailors on the warships began to enter combat positions. Anti-aircraft machine guns and anti-aircraft guns began to open and load.

Japanese fighter planes lifted off the aircraft carrier one after another and flew towards the outer positions.

The aircraft carrier being escorted this time was the Kaga, which had more than 70 carrier-based aircraft on it. Although there was a certain intention to assist the Shanghai defenders, Shimada never thought that he would go into battle before unloading the cargo.

"Woo~~ tu tu tu tu..." The National Defense Force aircraft fleet in the sky obviously did not expect to encounter Japanese fighter planes, but the appearance of Japanese fighter planes made them even more excited.

During this time, they have been performing bombing missions and strafing ground targets, and everyone is tired of it. Now there is finally a group of opponents who can fight with them. How can this make these war eagles unhappy?!

"Woo~~~" But these Japanese aircraft were obviously unusual. They roared and turned sharply to avoid the sudden encirclement and suppression by the war eagles of the National Defense Force. This actually surprised the war eagles of the national defense force.

But then they adjusted. The tactics of the National Defense Forces and Air Force have never been about dogfights. Instead, they constantly pull up the fighter planes and then annihilate the opponent with heavy firepower in a dive.

In this regard, the war eagles in the sky play very well.

"Boom, boom...boom!!" A Japanese fighter plane was hit by a 20mm cannon and suddenly turned into a ball of fire and fell from the sky.

Other Japanese fighter planes began to try to encircle and suppress the Wehrmacht Tiger Shark A that was being pulled up, but they did not notice that the other Tiger Sharks above their heads had already opened their bloody mouths.

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

"Boom, boom, boom...boom!!" Even though the National Defense Forces no longer have 20mm cannons, their airborne machine guns are not simple. The Japanese army's thin fuselage cannot block bullets at all.

As long as it was hit, it would explode into a ball of sparks, but the Japanese army was victorious because their fleet was large enough. More than sixty fighter planes took off, trying to encircle and annihilate the Tiger Sharks of the National Defense Forces.

At this time, the air defense siren at the National Defense Force Air Force Airport in Kunshan was also blaring. The war eagles of the National Defense Force preparing for war quickly began to change gear and board the plane.

Airborne machine gun ammunition, machine gun ammunition, etc. were all mounted on the Tiger Shark, and then under the command of the ground crew, it suddenly rose from the ground! Killing towards the sky above Shanghai!

Obviously, neither the National Defense Force nor the Japanese army expected to suddenly encounter each other here. This battle was fought in an extremely hasty manner. However, both the Japanese army and the war eagles of the National Defense Force had rich practical experience.

Therefore, all the equipment was prepared early, and after being mounted on the aircraft, it could immediately take off for combat.

The Tiger Moths on the bombing mission had already retreated when the Japanese fighter planes took off, and now the Tiger Shark A interceptors taking off to meet the enemy were all.

"Bang, bang, bang!" Finally, the war eagles of the National Defense Force, which were at a disadvantage in numbers under the encirclement and killing by the Japanese army, began to suffer casualties. The Japanese fighter planes continued to use their flexibility to encircle and suppress the war eagles of the national defense force.

The war eagles of the National Defense Force avoided the Japanese attacks by constantly raising their altitudes. The battle in the sky became fierce from the beginning. The fighting between the two sides became more and more fierce.

Tiger sharks of the National Defense Force were constantly being beaten until they fell sideways while emitting black smoke, and Japanese fighter planes were constantly being beaten into a ball of sparks and exploding from the sky.

But these Wehrmacht War Eagles did not back down. They continued to fight against Japanese troops that were twice as many as themselves. At this time, six Wehrmacht Tiger Sharks had been shot down.

Of course, the Japanese army didn't suffer much. Eight Type Zeros and four Type 97 carrier-based aircraft, this was the price the Japanese army paid. As the fighting in the sky began, the artillery on the ground also began to bombard the Japanese positions.

Amidst the roaring artillery, the Japanese troops on the position could only huddle within their own fortifications. Most of the downed tiger sharks chose to leave the battlefield as much as possible and make an emergency landing towards their own position.

Two of the few were forced to land between the positions of the Japanese army and the National Defense Force, and the Japanese soldiers who saw these fighter planes suddenly appeared on the position! Their purpose was simple: to seize these fighter planes and send them back to China for research.
Chapter completed!
