In recent days, Kuster has been oddly surprised, coming and going in front of several historic blacksmith shops, his face still dusty from time to time.

This made many people curious, and most civilians were able to get a closer look at the general's style.

It is worth mentioning that since the signing of the Moscow Entente, Austria-Hungary promoted Kuster to the rank of general; The Turkish side even gave him the title of "Marshal of the Caucasus", although the gold content is not large.

Germany recognized the status of its field marshal, but still regarded him as a foreign officer and did not allow him to participate too much in military command. Unlike the Caucasus, where Kuster was free to draw Turkish troops, and even put some of the ground snakes in the air.

The officials knew that Kuster was engaged in scientific research, and even if they could not understand why he was striking iron, they still had great wisdom compared to the people, and they declared to the outside world:

"Marshal Kuster is honing a weapon that can go up to the sky and into the ground, can also launch rockets, and can also extend into a few centimeters thick armor to protect the user at critical moments."

Many people come here, but they are not interested in it after one glance.

Compared with professional knife makers, Kuster is not only lacking in technique, but also the technology he uses is very backward.

He used the same indigenous method of forging swords since the Industrial Revolution. Several old blacksmiths around kindly reminded him that there was a power unit next to him, and it would be much more convenient to fuse billets, cast, forge, etc. But he just didn't listen, and instead said that hand-forged was better balanced.

Kuster's forging level is difficult to compliment, even the beginning of the smelting billet is not good, often the temperature is not well controlled, the billet is not heated well and begins to shape.

Over time, he also lost his confidence, and simply bought a good quality knife from the old blacksmith to play with.

However, his method of playing is also a bit unique, digging a piece of soil in the ground, putting carbon at the bottom, then putting a knife on top, and finally ramming the pit tightly with earth.

Hundreds of years ago, blacksmiths whose ashes had been dried should have known this technique, which was a method of carburizing, but it was very primitive and usually took several days to complete.

It's hard to guess what the hell Kuster is up to, but after he got it right, he went to work non-stop.

The efficiency of his work and the efficiency of striking iron are simply worlds apart, and he has produced more than a dozen drawings out of thin air in just a few hours.

The front and back of each drawing are different, and the development is extraordinary.

The R&D theme revolves around improving rocket artillery. Kuster found that the rocket's firing engine was perfect, but its guidance was very poor. Rockets can quickly rise into the sky, but because of this, the fuel will quickly burn out, and then if you want to drive, you have to look at the face of the wind god.

So Kuster planned to slow down the combustion rate of the fuel inside and remove some of the oxidizers to experiment again.

However, the results were not satisfactory, and the rocket did not even ignite.

Investigating the problem, it was found that due to the isolation from the outside world, the liquid fuel lacked oxygen, and could not react, so it naturally could not ignite.

Kuster pulled the original rocket over, dismantled the explosive device of the warhead, and conducted experiments on the outskirts of Berlin.

As Falkingham said, after flying less than 200 meters, the rocket ran out of fuel in mid-air, spun around and lost, and began to fall freely.

Several German soldiers were sent to look for clues, and within half an hour, something of value was discovered.

There were a few abrupt oil stains on the ground, and they were quite large, about the size of a small waterway manhole cover.

Go back and investigate, it is the fuel used by the rocket.

Now the reason has been found - his rocket is leaking.

But Kuster clearly remembers that his rocket does not leak oil! The Austro-Hungarian original rocket has an excellent effect in the Caucasus, whether it is precise positioning or long-range strikes, it can be done very well. So he was sure that the Germans themselves had something wrong.

Will the Germans probably admit it? No, you can't! They repeatedly insisted that it was Kuster's fault, not their workmanship, that they could have gotten to anyone's mouth on that ground, after all, that was the best in the world.

In desperation, Kuster had to give up on improving the rocket artillery, and only asked Franz, who lived in Austria-Hungary, to help him transport a few native rockets, and instead focused on armor technology.

The main reason for this is poverty. The Germans, on the grounds that he was not a German, did not allocate a penny to him for scientific research, and even he had to pay for the German soldiers himself.

Compared with a puzzle game that lasts for a long time, consumes a lot of money, and makes little profit, it is more effective to directly engage in a new set of things.

But soon, his money became more and more stretched. A marshal, who beat a superpower to the brink a few days ago, is almost unable to eat bread today.

Under such living conditions, he came up with the idea of returning to Austria-Hungary, but there was no news from Franz's side, and with the obstruction of Germany, he had to give up.

But soon he became rich. When Hindenburg saw that he stayed in the house day and night and did not come out, he felt pity and told him a little secret of getting rich:

"You made the Imperial uniforms."

After receiving the letter, Kuster jumped up from the ground in an instant, didn't even care why his clothes ended up in Germany, and ran directly to apply for a patent.

Because of the newspaper bombardment for several months, everyone who reads the newspaper in Europe knows what Kuster looks like, and they have a lot of respect for him.

But when he asked for patent fees, the German civil servant immediately turned his face and denied him, insisting that the military uniform was completely developed by the German Reich itself, but borrowed from Kuster in some "smaller" places.

Naturally, Kuster couldn't stand this kind of thief's behavior, so he grabbed his saber and started with those civil servants.

Since he was a well-known marshal, the civil servants did not dare to fight back, and fled to the streets to seek refuge from the police.

However, the police were useless, and Kuster cut it anyway.

Finally getting tired, Kuster "borrowed" a horse from the police station and began to ride and slash.

cut all the way to the prime minister's office, and the movement reached the emperor, and this ridiculous incident like child's play could be stopped.

The Germans quickly convened a meeting on the case, although the government cabinet strongly opposed it, suggesting that the emperor implement delaying tactics; But the emperor was very impartial and embarrassed, and insisted on agreeing to Kuster's patent claim.

As a result, Germany quickly incurred a large amount of expenses, but Kuster also kindly said that he could pay in installments instead of paying all at once.

A day later, he put his money in the bank, and the fortune rolled over more and more, so that Kuster had enough money to do research.
