The old man smiled when he heard the words of the reconnaissance battalion commander and said: "Young man, don't be unconvinced, I have been digging ice holes on the river to catch fish since I was fifteen years old, and thousands of ice holes will be drilled every winter, and I have been fighting for fifty years. ”

The reconnaissance battalion commander wanted to say more, but Lu Xinghua waved his hand and said, "Okay, don't say it again, we are here to reconnoiter the situation of Jiang Bing, and we are not here to participate in the ice hole fighting competition, what are we doing with these arguments?" Do you still have a task, do you bring a camera? ”

The reconnaissance battalion commander nodded, and Lu Xinghua said, "Take it out, prepare to use it for a while." After speaking, he said to the old man: "Uncle, please dig an ice hole out, don't break through, can you do it?" ”

The old man smiled and asked, "How can you catch fish if you don't break through?" ”

Lu Xinghua smiled helplessly: "We are not here to catch fish, let you beat you." The old man didn't say more, waved the steel drill and hit the ice, for a while the ice was flying, and a big hole was made in the ice, the big hole was very close to the water, and the water flowing below could be seen through the ice, and then Lu Xinghua said to the reconnaissance battalion commander: "Take pictures of this ice cave, pay attention to the situation inside the ice." ”

The reconnaissance battalion commander was surprised and asked: "What are you shooting this for?" ”

Lu Xinghua said: "Take a picture of the ice situation, and then send it to Lin Shuai, so that he can organize experts to analyze the load-bearing situation of the ice surface." ”

The reconnaissance battalion commander suddenly realized, and while speaking, the reconnaissance battalion commander finished taking the photo, and Lu Xinghua continued: "Bring a ruler, right?" Measure the thickness of the ice. ”

The commander of the reconnaissance battalion stretched out his hand and untied his armed belt and said, "The ruler is not easy to hold, so we draw the scale on the armed belt, and use the armed belt as a scale when we want to measure." As he spoke, the reconnaissance battalion commander measured the thickness of the ice with an armed belt, and Lu Xinghua said, "Write down this data." ”

The reconnaissance battalion commander took out a notebook and wrote the number on the notebook, Lu Xinghua pointed to the shore with his hand and said: "From here to the shore, it is about 300 meters away, and we make holes every 10 meters, and then record the data. ”

The reconnaissance battalion commander and the old man agreed, and soon finished the hole, recorded the data, and after everything was over, the reconnaissance battalion commander asked for a drill and tried to make an ice hole by himself, but it turned out that it was not as fast as the old man. Lu Xinghua sent the data to Lin Yuan, who immediately organized material mechanics experts to analyze the load-bearing capacity of the ice, and soon came to the conclusion that on both sides of the center of the river, the ice surface of about 70 meters could not withstand the passage of tanks.

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

The material mechanics experts immediately analyzed and evaluated Lin Yuan's method, and finally came to the conclusion that they couldn't bear it! Lin Yuan's heart moved, and he asked, "This method doesn't work, so how can I cross the river?" ”

An expert in material mechanics said: "The method of crossing the river is actually very simple, everyone knows that increasing the contact area of the road can reduce the pressure, and the ice surface will not be crushed. ”

Lin Yuan hurriedly asked, "What about the size of the plank?" ”

"Of course, bigger is better, and if we have planks with a length of seventy meters and a width of three meters, laid directly on the ice, the tank can cross the river without any danger," said the expert on the mechanics of materials. ”

Lin Yuan smiled when he heard this: "A wooden plank with a length of seventy meters? It's so long that our lumber mill doesn't have the mold to make such long planks. ”

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

Lin Yuan said: "Twenty meters is about the same. So Lin Yuan informed the timber mill to prepare such planks, and to complete the connection, and on January 11, the planks for crossing the river were prepared and transported to the front line, and on January 12, Lin Yuan's troops were dispatched and sailed to the south bank of the Tumen River.

In order to reduce the weight of the tanks, all tanks did not carry shells, anyway, the Japanese troops were several kilometers from the shore, and they were not worried that they would come over. The tank drove onto the ice, pressed the ice surface to make a "click" sound, and soon came to the edge of the plank, the tank crew's heart was hanging, the commander silently checked the towing rope attached to the back, once the wooden board could not bear the weight of the tank, the tank fell into the river, and other tanks would pull it out of the water through the towing rope.

The driver slowed down and drove onto the plank, and everyone's eyes were focused on the plank, although the data calculations of experts showed that it was safe to do so, but after all, it was a theoretical calculation, and there must be a big gap between it and the real situation, so everyone's hearts were hanging.

That's when something unexpected happened!

Everyone only heard a terrible whistling sound from the sky in the distance, the sound they were too familiar with, it was the sound of cannonballs falling from the sky, everyone was stunned, thinking: "Is this a cannonball?" Who's firing? ”

Just when everyone was speculating, the sound of the cannonball was getting closer and closer, and it was getting sharper and sharper, and suddenly, a huge explosion sounded on the ice, and the broken ice rose up with the splash of water, and everyone felt a shock under their feet, and couldn't help but think in their hearts: "What kind of cannonball is this little devil, why is it so powerful!" ”

Lu Xinghua saw that his troops were being shelled, and hurriedly looked into the distance, wanting 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. ”

At this moment, more and more shells broke through the air and the mournful whistling sound came from a distance, and in an instant, countless explosions sounded on the ice, broken ice and water splashed into the queue, and the ice cracked "click", after all, Lin Yuan's troops were troops with strict military discipline, and they did not have chaos when they were hit by this sudden situation, but anxiously waited for orders.

Lu Xinghua immediately ordered: "Attention of all troops, all withdraw to the north shore!" "Ordered the troops to retreat to the north shore at once, and at this moment, a shell exploded in the queue, and a TK-96 tank flew out like a leaf in a strong wind, turned over in the air, and fell on the ice, and dozens of fighters around it instantly became minced meat!

Lu Xinghua was shocked when he saw this explosion, and thought, "What did the Japanese army use?" Why is it so powerful? It was able to overturn the tank! ”

At this time, the explosion shook the ice, and soon terrible cracks appeared on the ice, and one crack extended under a tank, and the ice could no longer bear the weight of the tank, and it shattered with a click, and the tank fell into the water in an instant.

Despite this, Lin Yuan's troops were not scattered, and the infantry quickly retreated back to the north bank, but the armored vehicles were not good, as soon as they accelerated, the pressure on the ice increased, and several tanks and infantry fighting vehicles fell into the water, and at this time, the Japanese artillery bombardment was no longer limited to the ice, but extended to the troops on the north bank.
