Open an aircraft carrier to fight against Japan

The old man smiled when he heard the reconnaissance battalion commander's words, and said: "Young man, don't be dissatisfied. I have been making ice holes on the river to catch fish since I was 15 years old. Thousands of ice holes will be made every winter. After 50 years, tell me, you can be as fast as me."

The reconnaissance battalion commander wanted to say more, but Lu Xinghua waved his hand and said: "Okay, stop talking, we are here to scout Jiang Bing's situation, not to participate in the ice cave competition, what are you arguing about? You still have tasks , Do you have a camera?"

The reconnaissance battalion commander nodded, and Lu Xinghua said: "Take it out, prepare it for later use." After speaking, he said to the old man: "Master, please make a hole in the ice, don't pierce it, can you do it?"

The old man smiled and asked, "How can you catch fish if you don't pierce it?"

Lu Xinghua smiled helplessly and said: "We are not here to catch fish, so you can hit it if you want." The old man didn't say any more, and swung the steel rod to hit the ice. A big hole was punched in the ice, and the big hole was very close to the water surface, and the flowing water below could be seen through the ice layer. At this time, Lu Xinghua said to the reconnaissance battalion commander: "Take a picture of this ice hole, and pay attention to the situation inside the ice layer." come down."

The reconnaissance battalion commander asked in surprise: "What are you doing shooting this?"

Lu Xinghua said: "Take pictures of the ice conditions and send them to Lin Shuai so that he can organize experts to analyze the load-bearing conditions of the ice surface."

The reconnaissance battalion commander suddenly realized that while speaking, the reconnaissance battalion commander finished taking the photo, and Lu Xinghua continued: "Have you brought a ruler? Measure the thickness of the ice layer."

The reconnaissance battalion commander stretched out his hand to untie his armed belt, and said: "The ruler is not easy to hold, so we drew the scale on the armed belt, and used the armed belt as a scale when measuring." While talking, he measured the thickness of the ice layer with his armed belt, and Lu Xinghua said, "Write down this data."

The commander of the reconnaissance battalion took out a notebook and wrote the number on the notebook. Lu Xinghua pointed to the shore with his hand and said, "It is about 300 meters away from our place to the shore. We will drill holes every ten meters. , and record the data."

The reconnaissance battalion commander and the old man agreed to come down, and quickly finished drilling and recorded the data. After everything was over, the reconnaissance battalion commander wanted to pass the drill and tried to make a hole in the ice himself, but found that he was not as fast as the old man.Lu Xinghua sent the data to Lin Yuan, and Lin Yuan immediately organized material mechanics experts to analyze the load-bearing capacity of the ice layer, and quickly came to the conclusion that the ice surface of about 70 meters on both sides of the river center could not withstand the passage of tanks.

Lin Yuan immediately asked: "If a pontoon bridge is erected 70 meters away, can the ice withstand it?"

Experts in material mechanics immediately analyzed and evaluated Lin Yuan's method, and finally came to a conclusion that it was unbearable!Lin Yuan's heart moved, and he asked, "This method won't work, so how should we cross the river?"

An expert in material mechanics said: "The way to cross the river is actually very simple. Everyone knows that increasing the contact area can reduce the pressure, and the ice surface will not be crushed. If we lay large wooden boards on this ice surface, we can Let the tanks cross the river smoothly."

Lin Yuan hurriedly asked: "What about the size of the board?"

An expert in material mechanics said: "Of course, the bigger the better, if we have a plank with a length of 70 meters and a width of three meters, and lay it directly on the ice, the tank can cross the river without any danger."

Lin Yuan laughed and said, "A plank with a length of 70 meters? It's too long. Our wood factory doesn't have the mold to make such a long plank."

An expert in material mechanics said: "Then build a lot of planks with a length of 20 meters, and then splice those small planks together to form a large plank, which can also prevent the tank from falling."

Lin Yuan said: "20 meters is about the same." So Lin Yuan notified the timber factory to prepare such planks and complete the connection. Lin Yuan's troops were dispatched and headed towards the south bank of the Tumen River.

In order to reduce the weight of the tanks, all tanks do not carry shells. Anyway, the Japanese army is several kilometers away from the shore, so there is no worry that they will come over.The tank drove onto the ice, and the ice made a "crack, click" sound, and soon came to the edge of the board. The hearts of the tank crew were suspended. The commander silently checked the tow rope connected behind. Once the plank can't bear the weight of the tank, the tank falls into the river, and other tanks will pull it out of the water through the tow rope.

The driver slowed down and drove onto the wooden board. Everyone's eyes were focused on the wooden board. Although the expert's data calculations showed that it was safe to do so, it was a theoretical calculation after all, and there must be a big gap with the real situation, so Everyone's hearts are hanging.

At this moment, something unexpected happened to everyone!

The crowd only heard the shrill howling sound coming from the distant sky. The sound was so familiar to them. It was the sound of shells falling from the sky. Everyone was taken aback, thinking: "Is this the shells coming? Who is firing the shells? "

Just as everyone was guessing, the sound of the shells was getting closer and sharper. Suddenly, a huge explosion sounded on the ice, and the broken ice was accompanied by water splashes, and everyone felt the shock under their feet , I couldn't help thinking in my heart: "What kind of shells did the little devil use, and how powerful they are!"

When Lu Xinghua saw his troops being bombarded, he hurriedly looked into the distance, trying to find the Japanese artillery position, but he could only see the mountains in the distance, and there was no trace of the Japanese artillery at all. Lu Xinghua thought in his heart: " It's broken, it was hit by the Japanese long-range artillery!"

At this moment, more and more cannonballs pierced the air and screamed from a distance, countless explosions sounded on the ice in an instant, broken ice and water sprayed into the queue, and the ice "clicked" After all, Lin Yuan's troops are troops with strict military discipline, and they did not panic in such an emergency, but waited anxiously for orders.

Lu Xinghua immediately ordered: "Attention all troops, all retreat to the north bank!" After ordering the troops to immediately retreat to the north bank, at this moment, a shell exploded in the queue, and a tk-96 tank turned out to be like a leaf in a strong wind It flew out, turned somersaults in the air, and fell on the ice. The dozens of fighters around it were instantly reduced to pieces!

Lu Xinghua was startled when he saw the explosion, and thought: "What did the Japanese army use? Why is it so powerful? It can overturn a tank!"

At this time, the explosion shook the ice surface, and soon terrible cracks appeared on the ice surface, and a crack extended to the bottom of a tank. The ice surface could no longer bear the weight of the tank, and it cracked and cracked. The tank fell into the water in an instant.

Even so, Lin Yuan's troops did not disperse, and the infantry quickly retreated back to the north bank, but the armored vehicles failed. As soon as they accelerated, the pressure on the ice surface increased, and several tanks and infantry fighting vehicles fell into the water. The Japanese bombardment was no longer limited to the ice, but extended to the troops on the north bank.
