This canyon that can reach Heilongtan may not be very wide, but the average depth is more than fifty meters.

When people stand at the bottom of the valley and want to see it, they must have to raise their heads. Even if that is the case, they will only see a ray of sky. Even if someone deliberately pokes his head out on the cliff, they will not be able to see it in detail.

Then he is still fighting? He keeps tilting his head and holding a gun waiting for the Chinese to stretch out his head and let you hit him?

With the mentality of the Japanese infantrymen at that time, even if the Chinese did not shoot black guns down and smashed stones down, the results of the battle would be glorious enough.

Unfortunately, they were not facing the guerrillas carrying local guns they met in northern Shanxi, but the four-way group that was absolutely firmly in the top in equipment at this time.

If they could stand up the cliff, they could see that the Chinese in dark blue uniforms, in addition to guns in their hands, both officers and soldiers, without exception, had two small "fancy" bags hanging on their chests and behind their chests.

The Japanese may not understand that color is called camouflage, but they definitely know that bags that can carry on the front line of the battlefield are definitely not decorations for show.

That is the explosion No. 1 explosive pack produced by the Sixing Group Factory, which is specially used for individual soldiers!

If more than 600 people were carrying about 1,300, which was almost half of the output of military factories in this month.

Leng Feng and Shangguan Yun would rather bring less grenades that are easy to use on both ends of the offense and defense, and also carry these explosive packs that were originally used for attacking. In fact, this No. 1 explosive pack developed only a month ago has a very effective effect.

That is the masterpiece of Zhang Kai, a senior talent dug from the stingy old man in Tang Tuanzu, who has been calming down in the development of explosives for half a year.

The genius who was imprisoned in a prison had the biggest dream of developing explosives that could blow the entire prison to the sky, so as to reunite with his family who had been separated for many years. As a result, Tang Tuanzuo used money to help him complete the follow-up of his dream.

Not only did he redeem him from prison, but he also brought his family from Yuancheng. That's fine. The magical Tang Tuanzuo also knew explosive synthesis, and even gave incredible insights into chemically synthesizing explosives. In his eyes, the most advanced TNT explosives in the West are just the second-generation explosives, and he asserted that it would not take long to appear.

A handwritten chemical formula and a batch of chemical drugs specially designed for Zhang Kai's research were placed in front of Zhang Kai. The personal treatment was even the deputy chief engineer of the military factory. He ranked fifth in the military factory that the Sihang Regiment was most valued. This was the advanced treatment that many soldiers who followed the Tang Regiment did not receive.

But what shocked Zhang Kai even more was the meaningful sentence that Tang Tuanzu left to him: "Gunpowder was invented by our ancestors. We descendants have no reason to bury the glory of our ancestors. Deputy General Manager Zhang, you are already my best explosives expert in China at present. I believe you will not disappoint the entire army of the Four-Ring Group!"

As the saying goes, "A gentleman dies for his confidant." What Tang Tuanzu has done and said has reached this point. What else can I say about the former father of explosives in the arsenal of Jin Province? Just work hard and finish it.

Over 150 days and nights, this explosive genius only slept for an average of 4 hours a day and devoted himself to the research of new explosives day and night.

Ten years of prison disaster have been meticulously studying and accumulating accumulation under the intentional guidance of the Tang Tuanzhao, and after more than a hundred days and nights of tempering, it ushered in an explosion.

An ammonium nitrate obtained after countless tests appeared!

After this ammonium nitrification was detonated, the explosion power reached 1.2 times that of TNT explosives, and the explosion speed reached an astonishing 6,000 meters per second. With only 500 grams, it can completely blow up a machine gun castle made of reinforced concrete. Its power is so great that it seems to be blown by a whirlwind wherever it goes.

"Tornado Explosive" is the name given to this new explosive after the explosive test was successful.

Perhaps except for Tang Tuanzu, no one knows that this explosive has a more global name in the future - Black Sorkin Explosive.

In fact, the Western world had discovered this explosive component 40 years ago. It was just that this explosive could cause combustion and explosion when exposed to open flames, high temperatures, vibrations, and impacts. It is far less stable than TNT explosives, so it is difficult to use on a large scale.

However, human beings' persistence in developing murderous weapons may have exceeded the Creator's imagination. Until the end of World War II, under the tireless pursuit of military industry experts, the incorporation of beeswax into it could make the Black Sorkin gunpowder less likely to explode.

This also made the future famous iron fist rocket of the German Empire and also became a nightmare for Allied tankers!

The "Tornado Explosive" developed by Zhang Kai is of course just a primary version of the Black Sorkin explosive. Its power and speed of explosion cannot be compared with the Black Sorkin explosive that officially appeared on the stage of history, but it is enough for the Four Lines at this time.

In order to achieve greater explosion power, explosive packs made of yellow gunpowder had to be filled with larger explosives, resulting in a explosive pack weighing 10 kilograms or even 15 kilograms, which was extremely expensive to transport. However, the appearance of this kind of explosive can achieve the explosion effect of 15 kilograms of yellow gunpowder in just one kilogram.

Therefore, the combat mission of the four-row infantry regiment who rushed to the ridge was actually very simple. I lit an explosive pack, threw it down, and then quickly turned over at least ten meters away from the canyon and lay down in a position of hiding down in a position of avoiding shelling.

After a minute, rush back to the edge of the canyon, ignite the second explosive pack, throw it down, and then lie down.

During this period, they would not receive any military orders. Because everyone's ears were stuffed with cotton at the moment the signal flare rose.

In fact, no one could hear any other sounds since the first explosive pack began to explode.

As long as the person who is still alive, his ears are full of endless "booms" explosions.

Whether you plug in cotton or not, the terrible explosion will penetrate into your ears, making you feel that there is nothing else in this world, only a violent explosion.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! The earth is shaking, making the lying person feel that he is on the sea.

There is no need to discuss what kind of experience the Japanese infantry located in the canyon is. Even the initiators on the canyon, more than one-third of the officers and soldiers did not have the chance to throw out their second explosive bag according to the military order.

The air waves that swept through dozens of meters or even hundreds of meters into the sky will give people the illusion, as if as long as you stand up, you will be swept into the sky by this terrible air wave.

Faced with the threat of death close by, even the soldiers of the four-line regiment with a firm will be a little dazed and lost in that second.

For Masayoshi Oshima, several miles away, the first huge thunder that hit the ears was not enough to change his face, but the subsequent explosion was like the muffled thunder in the sky, endlessly.

The Japanese Army Colonel's face was as pale as paper in an instant.

The Chinese actually used unknown amount of explosives, which was a destructive attack for the infantrymen located in the canyon.

Even if his mind was blank at this time, the Japanese Army Colonel could fully imagine the miserable explosion in the canyon at this time.

However, the length of more than 3,000 meters, the officers and soldiers in charge of throwing the "Tornado explosive pack" dropped more than 960 explosive packs in total. If calculated based on the length and quantity, it can average up to more than 3 meters.

The power of the No. 1 explosive pack named by Zhang Kai, who has become low-key and restrained, has been tested for buildings, and has also tested live pigs and sheep, but it has never been practiced in actual combat.

The first time for the No. 1 explosive pack was handed over to nearly 2,000 Japanese soldiers located in the canyon. Both the explosives and the experiencers reached an unprecedented high dynasty.

The air waves formed by the 'Tornado explosive' are completely killing without dead corners. Even if a rock corner can block the air waves in one direction, you can't block all directions. There is always a force from an angle that can knock you away and then be torn by huge energy.

Not to mention the Japanese army that was bombed at the bottom of the valley, even many officers and soldiers of the Four Army Regiment who had been through many battles on the ridge were frightened by the waves of air rising into the sky.

Not to mention that many of the baggage soldiers dared not throw out the second explosive pack. Even Shi Hao himself crawled forward for several meters and encouraged himself in his heart before igniting the lead and threw the explosive pack several meters ahead.

The scene in front of us is really beyond the imagination of this infantry company commander who has experienced the battle of Sihang Warehouse.

The terrible air waves formed by the explosive explosive package were thrown in front of them, and the violent explosion had nowhere to vent in the canyon, just like a surging flood. Although it mainly rushes along both ends of the canyon, when encountering corners or rocks, the air waves that are blocked will soar into the sky.

In the face of violent energy, whether it is a height of tens of meters or hundreds of kilograms of boulders, it is a joke.

The stones shattered by the air waves were carried by the air waves and jumped out above the canyon dozens of meters high, even higher than the sky, and then fell violently.

Fortunately, the officers and soldiers of the Four Army Regiment were all equipped with steel helmets, and when they were lying down, they tried to curl up and reduce their body area. The stones that were crushed by the air waves were not too big. Even if they were unlucky to be hit by the stone, as long as they were not killed by the key, they would at least not be fatal.

But that's it. In the first round of throwing explosive bags, more than 20 people were injured by violent waves of rocks that rushed to the sky, and several of them were even smashed to pieces.

In the face of this artificial Tianwei, this is still considered good. The most terrifying thing is that a rock may be due to weathering. The violent explosion of the No. 1 explosive pack actually exploded that mountain body directly collapsed.

The three baggage platoon soldiers hiding on the rocks caught them off guard and hit the canyon with the collapsed mountain. The canyon at a depth of nearly 80 meters was raised by more than 20 meters. Whether it was alive or dead Japanese in the explosion, all had tombs at that moment, and they were purely natural.

Even the four regiments that threw the explosive bags were casualties, let alone the Japanese troops who were bombed under the canyon?

Since the first explosive pack explosion, no gunshot was heard in the canyon again. It was not that the Japanese army, who had been desperate and crazy, did not shoot upwards, but that the gunshots were completely submerged in the thunderous explosion.

In fact, when the first explosive pack was dropped, except for the 300 Japanese troops who had already walked out of the valley to build field fortifications at the entrance of the valley, even if they had walked only 100 meters away from the valley, they had lost all the heavy objects on their bodies, including half a squadron running wildly, and the 100 Japanese troops could no longer escape the sickle in the hand of the god of death who was grinning and crazily harvesting life.

Even if the 100 Japanese soldiers were 400 meters away from the explosion center, they could not save their lives. Because the narrow terrain of Heilonggou is really a paradise for explosives, and the air waves formed by the explosion could not radiate around like plains.

Except for a little bit of manic energy that dares to stop their catharsis from venting their power, most of the manic energy rushed into the sky along both ends of the canyon.

The Japanese army, with extremely rich combat experience, had actually done a great job. As the sound of the explosion came into their ears, the Japanese army, who had been stunned for more than three seconds, dropped their guns and ran towards the canyon that they could already see. While running, they dropped all the loads on their bodies that might tie their running, for only one purpose, to reduce the load, speed up, rush out of the valley, and avoid the air waves that followed.

If there were cameras at this time, you would find that although the Japanese army might not be the fastest-running person in the world, they were definitely the fastest-running group of 100 people in the world. In just ten seconds, they actually ran out collectively for more than 80 meters.

Human beings are indeed worthy of being the masterpiece chosen by the Creator. Even the shoddy and defective products are among them, they have burst out with almost brilliant potential at this moment.

But in the face of a kilometer-long air wave, not to mention the Japanese infantry wearing thick cowhide shoes with only two short legs, even in a jet plane with a speed of 2,000 kilometers per hour, they could not escape.

This chapter is not over, please click on the next page to continue reading! The Japanese army running in the front is probably only more than ten meters away from the valley entrance. As long as he is given another 2 seconds or even 1.5 seconds, perhaps he can cross the finish line in his eyes and use the solid and thick mountain walls to escape the violent explosion energy.

Then in the next 0.5 seconds, his wish came true in advance.

The rushing waves of air swept him out of the valley, not only sent him out of the valley entrance, but also into the sky. Then, in a beautiful arc, it was sent to the mountain more than 300 meters away from the valley entrance.

With a dull "dong", the thick human body was like a meat bullet thrown by a catapult, hitting a rock hard, splashing blood.

Without screaming, the Japanese infantryman who was about to escape had actually lost his life the moment the Qi Wave came, and the violent Qi Wave had shaken its internal organs into pieces at the first time.

It is easy to throw a human body weighing 70 kilograms to hundreds of meters away, and you can also imagine the terribleness of this violent energy.

Not to mention that the Japanese army, who had just been attacked and hid in a temporary shelter, were stunned and looked at the incomplete or incomplete corpses of their colleagues who rushed out of the valley like a scattered flower of the heavenly girl. Even the officers and soldiers of the Four Corps hundreds of meters away were shocked.

The exit of the canyon, which is more than ten meters wide, is like a bottle mouth full of manic gas and has been pulled out of the bottle. The violent energy throws the human body and gravel into the position like strong wind.

Without Leng Feng yelling, everyone immediately bent down and hid themselves in a trench with a depth of only 0.6 meters. The guns and bullets that died in the Japanese invaders during the battle were the fate of the soldiers, but if they were thrown by the explosives, they were not killed by the bombs, but were killed by the enemy who was killed, and then there would be no place to deal with the King of Hell!

In fact, it is still lucky to have the chance to be sent out of the valley like a cannonball by violent energy, at least there is a corpse.

Most of the Japanese invaders in the canyon did not have the chance to fly into the sky. They were basically swept by violent energy and smashed to the mountain wall, and then roasted black by the high temperature in the center of the explosive explosion to form the most realistic human murals. That is really terrifying.

After this battle, the villagers around Heilonggou decided not to pass through this canyon. The black stains everywhere on the solid mountain walls reminded people that more than 2,000 Japanese souls were buried in this valley.

Before even seeing the face of the Chinese soldiers, they were blown into the wronged soul of the mural.

Especially when the cold wind is howling, wailing sounds come from time to time in the valley, which can be heard for more than ten miles, making people feel cold when they hear it.

It was not until decades later that a scientific team came to this canyon called Ghost Gully Gully by local villagers, hoping to solve the reason why the whole ravine would make a whistling sound.

In the end, the mystery was solved by science. It turned out that the reason why people only heard wailings similar to humans in the cold winter was that there were a large number of gaps in the rock layer in this canyon. The wind speed was slow and good, but when the wind speed accelerated in autumn and winter, gaps of different sizes became horns, and the wind was blown out of the sound, like a howl.

The huge energy formed by nearly a thousand kilograms of "torphin explosives" has been shattered by nearly 4,000 meters of canyon stone. Has the fragile human body turned into slag?

Fortunately, the officers and soldiers of the Four Army Regiment did not throw all 1,300 explosive packs, otherwise this natural canyon might have been completely blown up.

I'm afraid that the infantry company led by Shi Hao and a baggage platoon would suffer more than 3 people killed in battle and 36 people were injured.

If one is not good, most of the people have to accompany the more than 2,000 Japanese soldiers in the canyon.

This is what is called fate!

After all, this is the territory of China, and the incense of our ancestors is not for nothing, so we can at least make some efforts.

Masaoyoshi Oshima, who was as pale as paper, was still alive. The Japanese Army colonel who had just entered the Tanikou left the canyon and entered a temporary shelter before the explosion.

It was okay, but in the battlefield completely covered by the wind and sand that had been swept up by the air waves, the Japanese Army Colonel involuntarily shed two lines of clear tears.

Although he wanted to say that he was fascinated by the wind and sand. But he knew that it was not.

The remaining limbs and bodies that kept flying out of the valley more than 200 meters away proved that the two elite infantry brigades under his command were finished.

Including those hundreds of people who have arrived at the valley entrance to deploy defense, with the wisdom of the Chinese commander who designed such a genius tactic, he would never miss such a good opportunity.

And if he wants to save them, he must increase his troops and cross mountains and ridges!

"Give power to the detachment captain. Our army was hit hard by an attack, and one was surrounded and requested reinforcements!" The eyes of the Japanese Army Colonel, who was still crying on his face, was red.

That was not only his last chance to save himself, but also his last chance to reach hundreds of imperial officers and soldiers at Gukou!

But the Japanese Army Colonel, who thought he would not easily abandon his officers and soldiers, completely entered the opponent's rhythm. He thought the opponent's commander had played all his trump cards!
