Cross the main square in front of the Paralympic and the Paralympic Bridge, Place Elysée, Place de la Concorde to rue de Rivoli. The shops were still open, gaslamps were lit under the arches, women were shopping in the shops, and some were eating ice cream at the Café Lethai and small shortbread in the English confectionery shop. Only a handful of mail cars depart from the Prince's Lodge and the Murris Lodge.

There are always many well-dressed gentlemen and ladies here, but this is not Xu Shushan's destination, through the lively bustling streets, going around, Xu Shushan went around into a small alley, in the middle of this small alley, there is no trace of light, in the dim alley, his feet feel that there are mud and puddles everywhere, this is a typical slum area, the reason why he came here is because Anthony rented a warehouse here.

Two months ago, because of the gunpowder burning accident, the school gave Anthony an ultimatum - either stop this "destructive activity" or move out of the dormitory, originally Anthony was ready to accept the former, ready to temporarily abandon his research, but with the funding of Xu Shushan, he moved out of the dormitory, rented a warehouse here, and continued the previous experiments.

"Am I making the wrong choice?"

Again, Xu Shushan, who realized that he had already spent more than five thousand francs on Antony and his experiment, muttered to himself.

If it had been a few months ago, Xu Shushan would not have been able to come up with this money, but three months ago, along with that letter, there was also a bill of exchange for 50,000 francs, which enabled him to finance Antony, but now he doubted his choice.

The reason for his doubts is very simple - Antony's experiments have not made much progress, and if there has been little progress, it has always been extremely limited, and even yesterday Antony asked him again for a hundred francs, saying that he wanted to buy a new raw material.

"This guy, don't you really think I'm the prince of China?"

Thinking of his jokes, Xu Shushan couldn't help but complain.

"No, it's the prince there, he must have wronged me!"

If there is no progress...... Although one voice in his heart told him that he should stop, another told him that if he stopped now, the investment of five thousand francs would be lost!

"Otherwise, just hold on for a while, ...... anyway"

Anyway, they still have money in their hands, but - they seem to be almost in France! Maybe there will be more places where the money will be needed.

Xu Shushan naturally thought of the news she saw in the newspaper -- "The forty-three Chinese students who arrived in England yesterday with the tea ship "St. Andrew" are all very young. They were all fine and wise ladies and gentlemen, and were more neat in appearance than those of their former compatriots who had visited England. Four guardians of the Chinese bureaucracy accompanied them. Local governments in central China have allocated £100,000 to fund their education. The Chinese government plans to send 50 to 100 students each year to study in the UK and other European countries......"

Although the newspapers said that the students were sent by the Chinese government, Xu Shushan had a feeling that these people must have been the work of his brother-in-law, whom he had never met, and where he found the students? Where do you get the money?

Although there are many problems in Xu Shushan's mind, he knows that there are two problems before him - one is to do a good job in the placement of those students, and the other is to do a good job - to set up a trading company in France.

However, he is not good at business, so until now he has not scratched his head, but has invested the money to start a trading company in Anthony, which does not make him seem a little uneasy.

"Maybe, I did something stupid this time!"

Just as he was thinking this, he came to the somewhat dilapidated warehouse, through the wooden door of the warehouse, he could hear the sound of gunfire coming from it, and after the first shot, as he had just entered the warehouse, another gunshot.

"Was he shooting with two guns? This guy, doesn't he know that gunpowder is also expensive? ”

Just when Xu Shushan was complaining in his heart, Anthony, who was holding a rifle in his arms, shouted excitedly as soon as he saw him coming in.

"Xu, my friend, look at this Prussian needle gun!"

"Isn't that what you bought for three hundred francs?"

The dissatisfaction in his heart made Xu Shushan's tone look a little unhappy, but Anthony, who was in excitement, did not pay attention.

"This needle gun was made by the Prussians decades ago, using a paper bullet and inserting a long needle into the paper pack, passing through the gunpowder and hitting the **** at the bottom of the warhead to fire. But it has two major problems, the first is that the bolt cannot be sealed, and the locking is poor when firing, not only the gas often escapes, but it rushes backwards into the shooter's face, and in the eyes, sometimes the locking completely fails. Another is the slender needle, which not only has to hit the **** and cause fire, but also is very easy to corrode and break when exposed to hot, high-pressure and corrosive gas for a long time. ”

Anthony's explanation made Xu Shushan nod a little impatiently.

"And then? Have you solved these problems? ”

This is the problem that Xu Shushan is most concerned about, and of course he is very aware of the problems of Prussia's needle gun -- in fact, since Anthony got this needle gun a few months ago, he has been committed to solving these problems, and he has tried many methods, but he has not solved the problem fundamentally. That's why he spends his money so much.

"Haven't we solved the second problem?"

Anthony looked at his friend with a smile and took out a paper bag, which was the cartridge of the paper bag.

"On the basis of the needle gun paper pack of fixed ammunition, we moved the fire cap from the bottom of the bullet to the bottom of the shell, and used a metal shell bottom with a horizontal firing pin inside, and rolled the shell with cardboard to roll the fixed ammunition. This shortens the length of the needle gun, and its lifespan is naturally much longer than that of the Prussian needle gun......"

This is not the most important question......

Xu Shushan muttered in his heart, at this time, he saw Anthony take out a rifle from the table, he was no stranger to that rifle, it was a rifle remodeled from an old MLE1842T rifle, in fact, it only used the front end of the barrel and hammer of the MLE1842T rifle, and the tail of the barrel was cut off and a rear-pull bolt similar to the Prussian needle gun was installed, but the bolt was fired with an old-style hammer, as for the rotating back-pull gun, it only played the role of locking.

"Look here......"

Pulling the bolt, Anthony handed the rifle to Xu Shushan. At the front end of the bolt, Xu Shushan saw a black object.

"It's ...... Rubber? ”

"That's right, it's rubber!"

Anthony immediately walked to the blackboard excitedly, pointed to the two sketches drawn in chalk on the blackboard, and said.

"The biggest problem of the Prussian needle gun's gas-holding is that it cannot overcome the expansion of gunpowder when burning, the first expansion will lead to the metal deformation of the muzzle gas closure ring, and finally with the continuous shooting, the leakage of gunpowder gas is almost inevitable, and I added a rubber air-tight sleeve to prevent gas leakage at the front end of the bolt, so that when the gunpowder explodes, under the gunpowder pressure, its front end of the needle sleeve will act backwards to squeeze the rubber air-tight sleeve, that is to say, the greater its pressure, the better the gas-holding effect, which is diametrically opposed to the Prussian needle gun... …”

In Anthony's explanation, Xu Shushan looked at the sketch on the blackboard, and its principle could be intuitively seen from the sketch, and Xu Shushan, as an engineer, naturally saw its feasibility at the first time.

"Success?"

He asked tentatively.

"I've shot more than a hundred times from this morning to now, and each time it's perfect, with almost no leakage of gas, and of course the firing reliability of the fire cap is not 100 percent, which needs to be improved, but believe me, it's better than the French needle gun! However, it leaves something to be desired......"

Picking up the Prussian needle gun from earlier, Anthony pointed to the bolt of the needle gun and said.

"The idea of the Prussian bolt design is good, in comparison, my gun ......"

He pointed to the rifle he had designed.

"After every reload, you need to pull the hammer, and the bolt is simply an ornament, so I think I can change its exposed hammer to a built-in firing pin that is integrated with the gun like the needle gun, so that it should operate more quickly, according to my estimate, it will definitely be able to shoot ten bullets a minute, my friend, believe me, we are rich!"

Just when Anthony looked at Xu Shushan with smug eyes, as if to say to him You have a very unique vision and invested in me, there was a shouting outside the door of the warehouse.

"Xu, are you there? Are you there? You have guests from China! It's a guest from China! ”

It was Mars, and before Xu Shushan could react, Mars was already full of joy and walked in with a few people in robes.

"They ......"

Looking at the comers in surprise, Xu Shushan almost couldn't believe her eyes, they, they are coming? Looking at the people in front of him, perhaps because he had never seen the relationship between the people of his hometown in a foreign country, he only felt that his eyes were hot.

Anthony, who was covered in gunpowder smoke, noticed his friend's gaffe and hurriedly stretched out his hand to introduce himself.

"I'm Anthony? Alfonso? Xia Saibo is Xu's good friend! Welcome to France! ”

They're coming, they're really coming!

At this time, facing the people in front of him, listening to the familiar words, Xu Shushan was even speechless with excitement for a while, and after a while, he quickly clasped his fists with both hands, and bowed over his head.

"You have been traveling all the way, and Shushan actually let you come here to look for it, which is really ashamed to ......" (to be continued.) )
