Lin Youde couldn't help but open his mouth wide: "Two thousand? ”

"Yes, two thousand, our mole was closely monitored before the attack was launched, along with other generals who knew the battle plan, and there was no way to transmit information, and he only connected with our communication station four hours before the attack began, and the communication station only sent the information to a place where it could send light signals to the aerial reconnaissance planes when the attack began." The voice of the fox on the other end of the phone was very strict.

Lin Youde smacked his lips.

The number of combat vehicles produced by Russia itself is not large, and because Russia does not have a relatively mature electric welding technology, the combat vehicles are riveted in many places, which makes even grenades can cause damage to the combat vehicles - the explosive impact of the grenade will bounce the rivets on the inside of the armor like bullets, killing and injuring the people in the vehicle, so Lin Youde almost ignored the Russian home-made vehicles. Only the tanks of the Americans were the opponents of the German armored forces.

Previously, Odin's Eye, based on a comprehensive interpretation of the situation of the railway counterparts and the arrival of ships in Murmansk, believed that the United States had supported about 2,000 Russian tanks in the past winter, because other places also needed to deploy tanks to counterattack the German armored forces, and Lin Youde estimated that the Russian army would put more than 1,000 tanks into the Bryansk offensive, and now the number has doubled.

"Did you gather the chariots from other places as well?"

"No," the fox paused, "I think our estimate is wrong, the total support of 2,000 to 2,500 vehicles was estimated in consideration of the fact that the United States itself has to put in the tanks in the Ming battlefield, and now I think that we have underestimated the number of tanks produced by the United States in the last six months, and the Americans are likely to supply the Russians in the first months of these six months, and then use the first batch of tanks produced by the tractor factory to complete the conversion to make up for the losses of their troops in the Ming. And our estimate does not take into account these tractor factories that have completed the conversion. Judging by the current state of affairs, the Americans may be able to produce 10,000 combat vehicles this year. ”

"Next year they will produce 20,000 units, and the year after that they will become 30,000 units."

The fox was silent for a while, and then said, "I'll go down and dismantle it, and I'll die of exhaustion after about two thousand dismantling it." Of course, they were all stupidly standing in a row, and I burned a dozen of them with a beam weapon. ”

"Will 2,000 be less?"

"It's a metaphor, you know? It's terrible productivity. ”

"There's bad news for you, because now the Americans are copying something that I forced me to make, you know what I mean?"

"Yes."

Lin Youde will not take the risk of talking about another time and space on the phone. The meaning of what he just said was that the M4 Sherman of the other plane was very faced, and the Americans of this plane imitated his masterpiece, so the quality of the tank was much better than that of the other plane.

"How the hell are we going to win against this monster?" The fox sighed, "No wonder you swore so confidently that Yingzhou's independence was going to end, indeed this kind of monster is not something that an island country can fight against." ”

"The way to defeat the United States, as I said, is to keep winning, accumulate advantages little by little, and finally force the Americans to sit down at the negotiating table."

"Didn't you defeat it completely?"

"How is that possible? If Isabella brought the British Empire over when she came to surrender, there might have been a drama, but now there is no drama, the geographical location of the United States is simply amazing, to be honest, I am really envious. ”

"Okay, I'm going to take off to contain Xiaoganggang, honey, you have to come on."

"It's useless for me to refuel, I have to refuel the soldiers on the front line. Okay, I'm hanging, you should be careful. After speaking, Lin Youde hung up the phone.

Then he turned his head to look out the window.

"What a strict expression." Ysera commented.

"There's no way not to be strict."

Lin Youde sighed, he stood up, came to the window, looked outside and fell into thought.

**

In fact, when he first mastered Germany, Lin Youde was thinking about a way to win against the United States, and after thinking about it, it seemed that there was only one way to make mushroom eggs - of course, if the people of the Institute of Theoretical Physics could make breakthroughs in other aspects and make some kind of two-way foil, they could also achieve the same effect, but Lin Youde's intelligence could only think of mushroom eggs, which were the ultimate weapon that really existed.

However, mushroom eggs are not something that can be made just by understanding the principle. Suppose there was a super jack-of-all-rounder who knew all the theories related to making mushroom eggs, and was sent to 191X and sponsored by someone who could provide him with all the manpower and material resources he needed, it would be impossible for that person to make mushroom eggs in the decade of 191X.

It's very simple, the process is not good.

The simplest configuration of the mushroom egg is the "gun type", which looks super simple, that is, two pieces of weapon-grade uranium that have reached a critical mass are combined together and exploded, but in fact it is very difficult to do. The biggest difficulty comes from the refining of weapons-grade uranium, centrifuges in 191X will definitely not be made, the United States in 194X can only use gas diffusion to make weapons-grade uranium, and China has not fully mastered all the processes required for centrifuges and gas centrifugation until the 21st century.

In 191X, no country even had the necessary processes to use the so-called gas diffusion method for industrial extraction, and it was impossible to build a giant separation plant like the Oak Ridge plant that supplied uranium for the Manhattan Project. In other words, it would take more than a decade to produce and prepare as much weapons-grade uranium as needed for a gun-type nuclear bomb alone.

In addition, the nuclear fuel utilization rate of the gun nuclear bomb is extremely low, and it is unstable, with the process of 191X, even if it is made, it is an unstable object that may explode at any time, and it may blow itself up.

The implosion type, which is more stable and reliable than the gun type, can greatly reduce the amount of uranium needed to make the bomb, and theoretically can take shape more quickly, but - but the implosion type of nuclear weapon needs to have a shell made of uranium-238 on the outside, which must be machined into a spherical surface and drilled in order to insert an electric detonator for explosives. In 191X there was simply not enough technology to process uranium-238 into the shape required for the conditions.

Because uranium is not dense, but hard, its chemical properties are also very active.

Why is the depleted uranium bullet powerful, because when the depleted uranium bullet hits the tank armor, the heat energy generated at the moment of hit will cause the uranium in the depleted uranium warhead to oxidize, and then release a lot of heat......

The depleted uranium bomb still uses uranium alloy, and the Americans studied it for 20 years before they began to make this kind of thing into a warhead in the 1970s.

And whether the pure uranium tube is 238 or 235, the chemical properties are much more lively than the uranium alloy used in depleted uranium bombs, this kind of thing could not be processed by any country in the world in 191X, so all kinds of pure uranium in this era are piece-by-piece, and after being prepared, it will be used for research, not to mention making it into a beautifully shaped spherical shell - you have to make holes in it......

All in all, unless the Traveler returns with the entire modern industrial system, it will not be possible to quickly produce mushroom eggs by 191X.

But if the all-rounder mentioned above, back to 193X, according to Lin Youde's view, it is entirely possible to make mushroom eggs at the end of the 30s, because human society began with the electrical revolution, and by the 1950s, the comprehensive technological level of advanced industrial countries would rise by one level almost every decade.

This is evident from the development of weapons, which began with the introduction of a new type of weapon almost every ten years, and the shape of warfare changed to a certain extent every ten years -- more than half of the credit for these changes was due to technological innovation.

Therefore, at the end of the 30s, the level of the world's advanced countries was already able to make mushroom eggs, and the traverser allowed scientists to take fewer detours, and it was entirely possible to get mushroom eggs out in the late 30s and early 40s.

But not in 191X and 192X, because there is a generational difference in craftsmanship.

Some people may say, can't the time-traveler make up for this generational difference?

Unfortunately, no. Technology can not take a shortcut, it is a very "pan" concept, including the technical proficiency of workers, the accuracy of production equipment and a series of complex things, he is the specific expression of the maturity of the entire industrial system, it is difficult to improve if you are not down-to-earth.

Therefore, the original group of "legendary scientists" in New China will put forward the idea of "we will do what others have done again in a down-to-earth manner to ensure that we master it", and this "mastery" is actually to master the relevant technology - technology, theory, these can be solved by sending international students to learn and introduce technology, but the process has to come little by little.

Lin Youde knows these things so well, because the associate professor who taught the history of modern science and technology in college was a fan of online novels, and complained about the novels that traveled through history all day long, "I got things out with a pat on my head, as if the ancients were stupid", "Especially those who wear modern history, where did the author get the confidence that he was smarter than those super masters at that time" "There must be a reason why those masters can't figure it out, I have studied modern history for more than ten years, and I found that the reason is craftsmanship".

There is only one circumstance in which the traverser can artificially accelerate the progress of the process with his own abilities: that is, the traverser himself is omniscient, familiar with all disciplines and fields, familiar with each step of the production process and related technologies. He alone can lead progress and change in all known areas of technology.

What else does this kind of person go through, honestly help the country run towards the four modernizations in his own time and space!

So Lin Youde decided not to engage in unrealistic things and not to point fingers at scientists after he crossed by himself.

What Lin Youde can do is to avoid a certain research direction from being noticed for a long time, and many technological advances in history are actually because no one has realized that "this is the road" for too long before it appeared so late, which is indeed true. But at other times, even though there is a theory, but it has not been able to create something, it is really not that scientists are incompetent, it is really impossible to make things.

Of course, after Lin Youde crossed over, he once missed computer technology because he was too busy, but fortunately, Dr. von Neumann did not go to the United States in this time and space, and Lin Youde was able to catch up.

But Lin Youde really can't help this thing about nuclear technology, he only knows a rough idea in this regard, and he can only gather all the nuclear experts he knows.

For example, Fermi was dug up by Lin Youdetongguò and his "master-apprentice relationship" with Born.
