..."Deputy team, news came from the forward observation post that the Japanese artillery fire has stopped, and now the main force is quickly moving towards the airport!"
Inside the airport's artillery defenses, news came.
Ye Min nodded and immediately issued an order: "The time is ripe, comrades, act quickly according to the plan."
"Yes!"
After the order was issued, the soldiers of the assault group and the soldiers of the guard battalion assisted in the operation led by Wei Heshang, the commander of the first guard battalion, quickly divided into two groups.
Along the way, we acted as a small blocking force to engage in firefights with the advancing Japanese army, limiting the advancing speed of the Japanese army and buying time for the soldiers in the rear to prepare for their actions.
Another group of soldiers, led by Ye Min, quickly and secretly acted in the airport area.
Everyone moved the bags of powder prepared in advance out of the bombhole, and then divided into multiple groups and spread them in all directions. The powder in the bags was blown by the strong wind of the blower and blasted with a shovel.
The spade was thrown out one by one.
In an instant, a large amount of powder was blown into the air in the direction of the wind.
"Pour it, pour it for me as hard as you can!"
Ye Min kept greeting, with a touch of excitement mixed in his words.
This is a large amount of combustible powder prepared in advance by the old director of the logistics department, including aluminum powder, sugar powder, wheat flour, sawdust, dried tobacco powder, etc.
At this time, the entire airport area had just experienced one round of shelling by the Japanese army, and the smoke emitted by the Japanese artillery shells had not yet dissipated. The terrain of the entire airport was relatively low-lying compared to the surrounding mountains, like a sinking
basin.
From this perspective, it is equivalent to a semi-enclosed area.
When the soldiers used shovels and blowers to quickly spread a large amount of combustible powder into the air, the airport area, which was already filled with gunpowder smoke, was filled with a large amount of dust suspended in the air.
The soldiers were well prepared and all wore special gas masks at this time. Even in such dusty conditions, their breathing would not be affected.
Everyone's hands and feet were very nimble, and they kept moving, and all the dozens of bags of powder prepared in one go were thrown out.
Looking out through the goggles of the gas mask, the air seemed to be dyed the color of solid powder. As the commander, Ye Min couldn't help but swallowed, and then specifically explained: "These flammable dusts are flying in the air."
After getting up, the most fearful thing is to see an open flame. Everyone must bear this in mind before completely retreating to the air raid shelter."
There were still gunshots coming from outside the airport.
That was the members of the assault force led by the monk, as well as the soldiers of the guard battalion, blocking the Japanese advance.
After Ye Min quickly got ready, he immediately arranged for communication troops to convey the news to the monk.
Monk Wei led the soldiers around him to retreat without hesitation.
Everyone followed the established evacuation route and quickly moved to the specially built underground artillery defense fortifications behind the airport.
These underground gun-proof fortifications are specially prepared and are not a straight line. There are many turns and twists inside to weaken the shock wave vented from the entrance of the cave.
When they were withdrawing, the monk and the soldiers around him were still laying wires on the ground. This was a detonation wire controlled by current. The other end of the connection was buried under a piece of ignition cotton a few hundred meters away.
By.
When the time is right, the soldiers will turn on the current of the control switch to close the circuit, causing the ignition wire at the other end to heat up rapidly due to the short circuit, and then ignite the ignition cotton covering its surface.
Thus, the open flame can be remotely controlled and the final plan can be completed quickly.
Everyone waited patiently in silence and with suppressed excitement.
...A moment ago, the Japanese colonel noticed that the small group of Eighth Route Army troops blocking the direction of the airport seemed to have chosen to retreat. This made him quickly make a judgment. It seemed that there were only a small number of Eighth Route Army combat troops inside the airport.
Therefore, after the blocking Eighth Route Army chose to retreat, the Japanese colonel did not hesitate to give the order to continue advancing.
The Japs' vanguard force of more than 1,000 people opened a military line and quickly invaded the airport area.
The following Japanese troops slowly followed up.
The little devils were also cautious enough. Before entering the airport area, they conducted a thorough reconnaissance around the airport. The outward spread of the cordon even spread for more than ten kilometers in one breath to confirm that there were no ambushes or lurkers around the airport.
artillery position.
At this time, the entire airport was quiet, and there seemed to be no more people.
After the leading kid quickly entered the core area of the airport, he was immediately affected by the dust suspended in the air and coughed violently.
What caught their eyes were the fragments of the plane that had been blown into pieces in the airport area, the debris on the ground, and the smoke-filled air that even obscured their vision.
Until this time, the Japanese did not realize that these planes were not real fighters, but camouflage planes specially built by a team of camouflage bureau Shi Dahu.
Speaking of the disguised airport and the fighter planes used to paralyze the Japanese army's judgment, Shi Dahu worked hard.
In order to simulate realistic fighter planes, these fake planes were specially built at the airport. Even the fuselage is made of iron sheet, except for the interior, which is empty.
In other words, this is an empty plane made of iron.
Then apply the corresponding paint. Let alone looking from a distance, even if you get close, you may not be able to see the clues.
Especially after the Japanese artillery bombardment, the planes at the airport were basically reduced to pieces.
But not all Japanese are blind.
Especially the Japanese colonel who led the troops into the forward position of the airport with a command knife in his hand. When he carefully observed the fragments of the so-called fighter jets that were blown to pieces inside the airport, he quickly realized that something was wrong.
These fighter jets should all belong to the empire. Although their armor protection is very weak, even if they were damaged in the previous rounds of bombardment, they wouldn't be blown to pieces like they are now, right?
This chapter is not over yet, please click on the next page to continue reading!
The colonel randomly picked up some fragments of so-called fighter planes, and immediately discovered that these iron pieces seemed to be pitifully thin, almost like a piece of paper.
How could this be the material used by fighter planes?
Amid growing suspicion, the Japanese colonel led the troops to continue to advance. The large amount of dust in the air made the colonel cough uncontrollably.
However, under the cover of the diffuse smoke, the colonel did not have too much doubts. He just thought that the air caused by the shells was bad.
It wasn't until the team reached the more central area of the airport that the Japanese army discovered a relatively complete so-called fighter plane.
Looking at it from a distance of tens of meters, there doesn't seem to be anything wrong.
It wasn't until the colonel led the guards to get closer and inspect that the problem was discovered.
"Baga, this is not a plane at all, this is a tin shell!"
Realizing that he had been deceived, the colonel clenched the command knife in his hand, exerted force with both hands, and stabbed the blade into the plane easily.
This is really a hell!
Out of a soldier's vigilance, he suddenly realized that if this airport was fake, did that mean it was a complete trap?
If this is a trap, does it mean that at this moment he has led the vanguard and fallen into the trap of the cunning Eighth Route Army?
"Asshole, no, the whole army will retreat immediately!" the Japanese Colonel roared.
Almost at the same time, the forward observation post arranged by Ye Min quickly got back into the air-raid shelter and said at the same time: "Deputy team, the main force of the Japs has entered the core area of our airport!"
Ye Min nodded and without hesitation, "Do it!"
Several soldiers who had been prepared for a long time pressed the connectors in their hands at the same time, and the circuit extending several hundred meters away from the bomb hole was quickly connected.
Soon, the wire covered under the ignition cotton began to heat up rapidly, and the temperature rose rapidly. Soon, in the rising black smoke, it reached the ignition point of the ignition cotton.
Huh——
Small flames suddenly broke out from igniting cotton in many areas of the airport, and then local fires quickly ignited.
The open flame quickly ignited the dust concentration in the air that had already reached the flammable and explosive limit.
What is the situation like at this time?
——"Let me explain to you what exactly this dust explosion is about, and what conditions it requires... These combustible powders are suspended in the air in a limited space, and then they can form dust clouds with the air. This
At any time, once it encounters an open flame, these combustible dusts will burn quickly, and then cause a chemical reaction with a sharp increase in temperature and pressure, such as an explosion in a large-area chain effect!"
Boom——
Monk Wei, who was doing science popularization with the soldiers from the guard camp who didn't know much about the situation, just pretended to be a cultural person and finished the science popularization of the cause of the dust explosion.
The violent explosion and the movement caused by the released energy were immediately transmitted through the surface to the bomb-proof cave.
Feeling the big movement on the ground, the soldiers couldn't help but look shocked.
"My dear, this feels like the Japanese dropped thousands of bombs on our airport at once!" A soldier said while swallowing his saliva.
Ye Min felt it was a pity: "I always feel that it is almost boring. It would be more comfortable if we could witness this wonderful show with our own eyes!"
At this time, Ye Min’s so-called comfort is like this:
The large-scale dust explosions were like a chain reaction. They connected together before the Japanese army had time to make any reaction, and spread to the entire airport area where the dust spread.
There was nothing else going on at this time, except for the rapid explosions caused by several open fire areas, which evolved into a large sea of fire in an instant, and then surged outward crazily, like terrifying fire dragons, baring their teeth and claws.
, then everything in this area was swallowed up.
The Japanese colonel, who was also enveloped by the explosion, didn't understand what was going on at all. His round eyes were full of horror, and then he was directly overwhelmed by the surging sea of fire.
Devoured by the intense heat, the Japanese's flesh and blood were burned in the blink of an eye.
The Japs in the central area of the explosion were directly roasted into jerky under the continuous high temperature.
The sudden and terrifying explosion turned the entire airport into a hell on earth.
The more than 1,000 Japanese troops who were the first to enter were completely swallowed up by the sea of fire. In the central area, until the flames shrank back, no living person was seen coming out of it.
More than 500 Japanese troops who were advancing forward at the front fortifications of the airport saw the roaring fire dragon. Some of them were slow to react and froze on the spot, and then were swallowed up by the flames.
Even if he didn't die, he would still be seriously injured.
The one who reacted quickly fell to the ground immediately, and then pressed his whole face hard against the dirt. He escaped unhurt and only suffered some burns.
These soldiers who were only in the fringe area were hit so hard, let alone the main vanguard force that had entered the airport area.
The Japanese lieutenant colonel who was staying behind to lead the team looked at the sea of fire in the airport area that was almost engulfing the sky and the earth. For a moment, he was almost frightened to death.
The Japanese thought this was the end.
Boom——
Then a second explosion occurred again. This time, the sea of fire surging outward became even more violent.
After a dust explosion, the air wave of the first explosion will blow up the dust deposited on the equipment or the ground. A negative pressure will be formed in the center of the explosion within a short time after the explosion, and the surrounding fresh air will fill in from the outside inward.
Mixed with raised dust.
This caused a secondary explosion.
In the secondary explosion, the dust concentration will be higher and the power will be even greater.
Such multiple explosions are typical characteristics of combustible dust explosions.
In the bomb-proof cave, they felt a more violent explosion than the last time. Even Ye Min, Monk Wei and his party looked at each other in shock.
Some soldiers lamented:
"I used to think that only our machetes and our bullets could kill the Japs, but now I have become more knowledgeable. Dozens of bags of powder can also be used to kill the Japs, and hundreds or thousands of Japs can be killed in one breath.
Devil."
"No wonder our detachment leader often says that once we have culture, we can even be more powerful at killing Japanese!"
Another soldier said: "The famous saying of our old regiment leader: learn mathematics, physics and chemistry well, and you will not be afraid of killing all the Japanese! I didn't understand what it meant before, but now I understand it completely."
...After the second dust explosion, the casualties of the Japanese army became more and more heavy.
Even the Japanese colonel who led the team was completely swallowed up in the sea of fire, and there was no possibility of survival. After the remaining Japanese lieutenant came to his senses, with a face full of panic, he hurriedly issued the order to retreat. In his opinion, the airport in front of him is simply hell.
He has completely lost the courage to continue attacking, and he does not believe that there can be any living people in the sea of fire that explodes again and again.
"Withdraw, retreat strategically immediately!"
During the big explosion, the mountains to the east of the airport were still quiet. There were some secret reconnaissance posts arranged in advance by several leaders of a team in the mountains.
They can be said to be the most perfect witnesses to this earth-shattering dust explosion.
At this moment, the faces of these soldiers were frozen with the look of seeing a ghost.
There is only one thought brewing in their hearts:
When I report to the group leader and the others later, how should I organize my language...
