The classification has fallen to second, brothers, do you still have a monthly pass in your hand?

*************

When he sat on the road again in the jeep, Qin Chuan kept a question in his mind...... In fact, the best material for making armor-piercing projectiles is not tungsten, but lean shafts, the main component is shaft 238, which is used to prepare by-products of radioisotopes such as shaft 235, which is the so-called lean shaft bullets.

Like tungsten, the lean shaft has the characteristics of high density, high hardness and high toughness, which makes it very suitable as an armored projectile...... The high density makes it have more kinetic energy after being launched, the high hardness allows it to penetrate the target armor, and the high toughness makes it difficult to break.

In particular, the poor shaft bullet also has a self-sharpening ability that the tungsten core bullet does not have.

The vast majority of substances are self-blunt, for example, sharp kitchen knives become more and more blunt the more you use them, and they need to be sharpened to regain sharpness, and the same is true for tungsten core armor-piercing bullets, which will become more and more blunt due to collision and friction with the armor when it hits the target and penetrates the armor, so the penetration will become worse and worse.

This is not the case with poor shaft bullets, which will peel off in a small area like a crystal after hitting the target, so they will constantly keep the tip sharp, which will make it much better armor-piercing than tungsten core bullets.

However, in the end, Qin Chuan still did not put forward this idea...... On the one hand, it is because in this era, tungsten core bullets are completely sufficient, and there is no need to be so complicated. On the other hand, this technology, that is, refining the shaft 238 and using it as a material to make armor-piercing bullets, is too advanced for Qin Chuan to justify himself.

The journey was relatively smooth, mainly because the almost continuous bombing by the American and British forces made Qin Chuan and his party have to travel day and night.

The bombardment of the American and British troops may be considered dangerous to the French people who have been living in peace, but for Qin Chuan and others, it is not a matter at all...... These bombers will not target civilian houses, because this is France.

Of course, there will inevitably be accidental bombing, after all, precision-guided bombs have not yet appeared in this era, and there are so many bombers sent by the United States and Britain, among which there are inevitably some rookie pilots.

Qin Chuan has seen a row of houses that have been bombed into ruins...... The target of the bombers was supposed to be a bridge dozens of meters away, but the bombs were all dropped on civilian houses, and the bridge did not happen at all.

A group of French people wept and tried to save their loved ones from the rubble, but it was clearly in vain.

Qin Chuan knew that it would be more difficult to find a few survivors in such a complete destruction than to win the lottery.

However, there are not many such phenomena.

So Qin Chuan and Colonel Slain can live in a French house during the day...... These dwellings were open to German officers, and all you had to do was pick the biggest and the best out of them, because it meant that the owners were richer.

Then knock on its door, and the owner will give everything he can to entertain the "visitor".

This made Qin Chuan feel a little guilty, because all the time, Qin Chuan could see the panic on the faces of the masters, and sometimes Qin Chuan could scare the masters into shivering just by coughing.

Qin Chuan wanted to tell them that they didn't have to do this, they were just to avoid the bombardment for a while and leave at night, but Qin Chuan knew that it wouldn't be useful.

Especially at this time...... The French also knew that the United States and Britain were about to fight, so their minds would be in a state of hesitation, excitement and contradiction.

They will guess whether the Americans will win the battle or the Germans, and if the Germans will win everything will remain as it is, if the Americans will win...... What will the Germans do before leaving?

These thoughts will make all French people feel up and down in their hearts, and sometimes the more you comfort them, the more they will feel that this is "crocodile tears", so in the end Qin Chuan learned to give up.

Colonel Slane told Qin Chuan a trick: "If you act like you're busy and tired, treat them as air...... Then they will feel much better! ”

Qin Chuan tried it and found that it was indeed the case.

Therefore, in the next few days, Qin Chuan often discussed something with Colonel Slein insolently after living in the house, and occasionally let out some laughter, as if the Frenchman who was busy next to him did not exist.

However, this kind of pretended thing still annoyed Qin Chuan, and they finally arrived in Paris a few days later.

Unlike the tense atmosphere that Qin Chuan saw along the way, Paris did not have the tense atmosphere before the war at all, and it was still full of people and cars on the streets...... It was three o'clock in the morning when Qin Chuan and Colonel Slain arrived in Paris, and it was pitch black everywhere else, partly because they had to sleep, of course, but partly because there was a fear that the bombers would be targeted by the lights on.

Although this worry is unnecessary, the people will always be the most considerate.

Paris, on the other hand, is brightly lit at this time, and jeeps can occasionally hear music and laughter as they pass through the streets, and occasionally you can see dancers dancing in pairs through the windows, or a few drunken officers laughing with French women.

The car stopped in front of a building, which was the headquarters of the German army in Paris, and there were several guards standing at the door who were smoking cigarettes and talking about something, and when they saw Colonel Slein and Qin Chuan getting out of the car, they hurriedly threw away their cigarettes and stood up to salute.

"I'm sorry, sir!" An ensign came out of the booth, saluted the two of them, and said, "I need your papers!" ”

Colonel Slane and Qin Chuan handed over the documents.

After the second lieutenant took the certificate, he skillfully flipped it open and compared it with the two of them, and then there was something strange in his eyes.

"I'm sorry, Colonel, Lieutenant Colonel!" The second lieutenant said, "I didn't know it was you, it's an honor to meet you......"

"Can we go in?" Colonel Slain asked impatiently.

"Of course!" The second lieutenant replied: "But General Rommel told me, and he told you to go to La Roche Gilon to find him!" ”

"General Rommel isn't here?" Qin Chuan asked.

"Yes!" The lieutenant replied, "He moved out of here a few days ago!" ”

A few days ago, Qin Chuan and the others were still on their way here...... Although Colonel Slye had the radio with him, he did not receive a telegram from Rommel.

"La Roche Gillon?" Colonel Slane asked.

"Yes!" The second lieutenant replied: "37 kilometers downstream along the Seine, there is a village, and that is La Roche Gillon!" ”

Qin Chuan and Colonel Slein glanced at each other, both of them knew that this was Rommel's style, he didn't like the bustle of the city, he preferred the quiet countryside.

However, it was later discovered by Qin Chuan and Colonel Slein that Rommel had moved his headquarters out of Paris not because he liked the quiet countryside, but because he could not find recognition here.

In fact, it's not just "unable to find identity", it's not an exaggeration to describe "isolated" or "marginalized".
