The three marshals immediately made a decision, promoted Fang Xiaoyu to lieutenant, and said that they would submit it to the emperor, and there would be a reward later. Xia Ziqing looked stunned in the back, Fang Xiaoyu, this kid is really a monster, I didn't expect that he was not only a second lieutenant on the first day he joined the army, but he was promoted to a lieutenant the next day, if he did this, he would not become a marshal a month later.

With this training plan, the three marshals were in a good mood. The three of them got together and began to study, and many staff officers also came over. Seeing that everyone was focusing on the training plan, Fang Xiaoyu was about to slip away, after all, he still had to go to Zhang Peiyun to customize brewing equipment. As soon as Fang Xiaoyu walked to the door, Marshal Xia Jun raised his head and said, "Fang Xiaoyu." "Here." Fang Xiaoyu was startled and hurriedly responded.

"I know you're busy, just take time out to come for a few days a month." After speaking, Marshal Xia Jun smiled and said: Also, next time you are in the staff war room, the noise is quiet, and it is forbidden to make noise here. Fang Xiaoyu first broke out in a cold sweat, and then his face was flushed with shame, he finally realized that after he finished shouting the report, he had so many strange eyes staring at him.

Walking out of the army staff, Fang Xiaoyu let out a sigh of relief, it was really depressing in there. Since Xia Ziqing didn't send him again, Fang Xiaoyu had no choice but to walk to the military workshop by himself. Fang Xiaoyu, who was just ten years old, rarely went out before, and spent much time learning the history, geography and customs of this place with Xiaofeng, even if he came out either by sedan chair or by carriage, today he can finally walk once, and also feel the prosperity of the capital of the Lanfang Empire. Not far away, Fang Xiaoyu turned into a commercial street, the road here is not spacious, the road is lined with stalls on both sides, and there are many shops in between.

Fang Xiaoyu walked and walked, and a shouting voice came into his ears: "Come and buy it, delicious sugar cubes." There are also candy cubes, Fang Xiaoyu was a little surprised. In his previous life, he liked to eat sugar, but the Fang family was a big family, so he naturally ignored the things sold at this kind of street food stalls, so after eight years of coming to Wangxiangxing, Fang Xiaoyu mostly ate honey known as aristocratic food, and at most drank lotus seed porridge mixed with brown sugar, and the yellow and clear color at that time scared himself.

Fang Xiaoyu walked over and found neat wooden boxes on the vendor's cart, with black, red, and yellow sugar cubes in the boxes. Fang Xiaoyu asked the vendor suspiciously, "Why don't you have a white one?" "White?" The vendor was stunned, although the person in front of him was short and looked like a child, but the officer uniform he was wearing made the vendor dare not slack off. The little trader immediately smiled and said, "Master Jun, I have been a trader for twenty years, and I have always been sugar cubes of these colors, never white." ”

Hearing his words, Fang Xiaoyu's eyes lit up, it turned out that there was no white sugar in this world, this was a good way to make money. I always wanted to rely on Xiaofeng's research results, but I didn't expect that I could also think of ways to make money. First of all, this white sugar is, although I have not seen the production process of white sugar, but I know the decolorization method of the famous yellow mud water in history in detail, which is also thanks to my own reading history books, because I was curious about the "Heavenly Creation" written by the great scientist Song Yingxing of the Ming Dynasty. It's really good, Fang Xiaoyu immediately decided to order some more large wooden barrels and funnels at Zhang Peiyun's place.

Thinking of this, Fang Xiaoyu happily sped up and ran towards the Xia family's military workshop. The candy seller looked at the back of the drifter and muttered: "This military master is really strange, why did he suddenly leave without buying sugar." With that, the vendor withdrew his gaze, it was just a small episode in his life, and turned his head, and he began to greet the next guest again.

Hearing that Fang Xiaoyu was coming, Zhang Peiyun hurriedly greeted him. The craftsmen who watched were amazed, they never expected that the chief engineer, who was usually high, even Marshal Xia saluted three points, and would personally greet such a little child. Fang Xiaoyu smiled when he saw Zhang Peiyun: "Chief Engineer Zhang, today I came to trouble you to make something for me." ”

Zhang Peiyun also said: "No problem, I also happen to have something to ask you, I didn't expect you to come, it's really good." The craftsmen next to them were surprised when they heard the conversation between the two, who was Zhang Peiyun, the chief designer of the weapons of the Lanfang Imperial Army, who actually wanted to ask such a little child. But looking at Zhang Peiyun's expression, it didn't look like flattery, but sincerely, and what was even more exaggerated was that Zhang Peiyun's deputies also looked like a matter of course, and warmly invited Fang Xiaoyu to the office to sit down.

When he came to Zhang Peiyun's office, Fang Xiaoyu took out his design drawings. Zhang Peiyun originally thought it was a firearm drawing, but when he took it, it was some strange barrels and pipes. He asked curiously, "What are these things?" What's the use? Fang Xiaoyu said: "This is something that my family's workshop uses, as for the use, it is a trade secret." "Just kidding, if Fang Xiaoyu explains all the uses, what kind of money will he make, you must know that the Lu Dao Xia family controls eighty percent of the handicraft manufacturing industry in the entire Lanfang Empire, and if he tells them, he won't have to play.

Zhang Peiyun also knew that Lu Dao shouldn't ask, he just laughed dryly, handed the drawings to the assistant next to him and said: "Take these drawings to the workshop, let them make them quickly, and then send them to the ......" Zhang Peiyun didn't know where to send Lu Dao, he turned his head and looked at Fang Xiaoyu. Fang Xiaoyu said with a smile: "Send it to Lanting Villa in the north of the city." Zhang Peiyun nodded and instructed his assistant, "Go quickly." The assistant nodded, and took out the drawings.

Zhang Peiyun turned his head and asked with a smile: "Little Brother Fang, I have a problem that I can't solve, I hope you can help." "Another problem?" Fang Xiaoyu was surprised. Zhang Peiyun said with an embarrassed face: "This group of generals in the capital is really bright, I heard that we have a new weapon design plan and they all came, I just made two sample guns yesterday, and they are very satisfied after trying it." Listening to Zhang Peiyun's nagging for a long time without getting to the point, Fang Xiaoyu asked out loud: "Satisfaction is a good thing, what's the problem." Zhang Peiyun said: "But they have used the rear loading gun with fixed ammunition and ask me to help them improve the revolver, saying that it is too troublesome to load the propellant and the projectile separately, and also let me design a pistol with fixed ammunition, I am worried about this matter." ”

Zhang Peiyun stretched out his hand and took out a revolver specially equipped by the military for officers from the drawer of the table and said, "You see, our pistol has cut a groove in the back of the revolver in order to reload. If you switch to fixed ammunition, it is not a problem to hinge a firing pin behind the runner. However, this groove is too small to completely fit such a long fixed load into it, but if the groove is enlarged, it will affect the structural strength of the whole gun, and it is easy to cause the gun body to break during the firing process. Fang Xiaoyu took the pistol, looked at it and nodded: "It turns out that this is the case, it is very easy to solve." After listening to Fang Xiaoyu's words, Zhang Peiyun's eyes lit up, and he quickly asked his assistant to take out a pen and paper and ask Fang Xiaoyu to draw a picture for him.

Taking the pen and paper sent by Zhang Peiyun, Fang Xiaoyu drew again, watching the figure of a pistol gradually take shape in Fang Xiaoyu's hand, Zhang Peiyun's eyes lit up. Fang Xiaoyu drew a Colt 'Lightning' double-action revolver, and in order to make Zhang Peiyun see more clearly, he also deliberately drew the revolver mechanism of the gun next to it. In this worldly revolver, the revolver cannot be posed, because there is no such need to use split ammunition.

Fang Xiaoyu finished drawing the picture and explained to Zhang Peiyun: "You see, as long as such a mechanism is added, so that the runner can swing out to the left to load and clean up the bullet nest, and the pin is fixed after reset to prevent the bullet nest from loosening when shooting, and this design is double-action, which can be fired continuously, and you don't have to pull the hammer every time you fire a bullet." Zhang Peiyun exclaimed: "It's really a genius design, so that the revolver is much more convenient, it's really good, you can actually swing the revolver to the left, I think this new revolver is called a revolver." ”

Fang Xiaoyu was stunned when he heard this, and then laughed, the name of the revolver originally came from this, this time there was another weapon patent, and he had money again.

solved the problem in his heart, Zhang Peiyun also talked a lot. Fang Xiaoyu took the opportunity to ask him about artillery. There is no way, Fang Xiaoyu's weapon knowledge is relatively simple, in this world, he can be said to be god-level in terms of firearms and warships, of course, it is limited to design, and he doesn't know much about such high-tech things as the power system of warships. As for artillery, tanks, airplanes, etc., they are only at the level of amateur military fans. Although there are no tanks and planes yet, this artillery still needs to be deeply understood, this is the god of war.

Zhang Peiyun is also very fond of this genius little designer, he almost taught his artillery knowledge, although it is only the knowledge of front-loading guns, which also benefits Fang Xiaoyu a lot, especially the selection of barrel materials, the calculation of chamber pressure and artillery sights.

After chatting for a while, Fang Xiaoyu got up and said goodbye, Zhang Peiyun would send someone to Lanting Villa to do the good things, naturally he didn't have to worry about it, and Fang Xiaoyu, who went home, helplessly found that he was going to walk again. Walking on the road, Fang Xiaoyu secretly decided that he must learn to ride a horse if he had time. Riding a sedan chair is too time-consuming, and the shock absorption of a carriage is too poor, in this era when there are no cars and planes, riding a horse is the best choice for yourself.

The next morning, Fang Xiaoyu decided to go to Lanting Villa, after all, set up the two factories first, and put them into production one day earlier, and see the benefits one day earlier. Originally, Fang Xiaoyu wanted to ride a horse, but after trying it, he found that riding a horse is not so easy to learn, especially since he doesn't have a little foundation. In desperation, he had no choice but to take a carriage.

Now Fang Xiaoyu has two more personal guards Zhang Tong and Liu Junxi by his side, and the four guards when he went to Lanting Villa last time were temporary, and they had already been returned to his eldest brother Fang Dingguo. And these two guards learned from the Ministry of Industry last night that the Xia family had registered three weapon patents for Fang Xiaoyu, and after calculating it, they found that Fang Xiaoyu had become a cornucopia. In order to protect this cornucopia of the Fang family, he discussed it with his two brothers and decided to send two masters to protect Fang Xiaoyu's safety to avoid accidents.
