A dinner party, eat until the sky is dark.

At the self-service party full of dry goods and fruits, and enough drinks, Zhang Guanghua frequently raised his wine glass and toasted everyone in the Chamber of Commerce. Team cohesion is invisibly enhanced......

I drank a lot of wine with the craftsmen last night, and Zhang Guanghua was also drunk, and when he woke up, he was already on the rise. Walking on the street last night was still lively like the New Year, and some people even set off firecrackers, and the barracks were also brightly lit, and it was also a carnival all night. But today, the whole city was quiet.

The army has Li Da training, the city has Zhao Shan to manage, and the law has Huang Kaizheng and the village chief to help, so there is nothing to do with him Zhang Guanghua.

After washing, Zhang Guanghua is ready to inspect the workshop, which is the foundation of his business empire! But at this time, he realized that he was so busy that he didn't know where the workshop was, and it seemed that he had no choice but to go to Shen Lina first.

"Ouch! Shopkeeper Shen, where is this going? As soon as he walked over, Zhang Guanghua found that Shen Li was about to go out.

"I just got up and was about to go to the blacksmith shop, where are you, military advisor?" Seeing Zhang Guanghua coming, Shen Li retracted his steps and prepared to invite him into the house.

"No, I'm going to the workshop too, let's go together." Zhang Guanghua hurriedly said.

Walking and chatting on the road, Zhang Guanghua also learned about Shen Li's situation in the past month or so. When attacking Anxi County, Zhang Guanghua recruited more than a dozen people, including Shen Li and Liu Carpenter, taught them engineering drawing, and gave them drawings for arquebuses. Shen Li has read books, and he has the foundation to learn the fastest, followed by Liu Carpenter, who has rich work experience.

The research and development was handed over to Carpenter Liu to lead the team, and he was quite creative, first using wood to make a model to familiarize his subordinates with the structure. Later, because Xianyou, Dehua and other counties were sent to him, he conducted a mapping study of the firecracker. Considering the limited funds and the long time and difficulty of building a gun from scratch, he decided to improve the existing gun first. Unexpectedly, after adding the fire rope, trigger and wooden support, even without the primer pot, he achieved good results, so his strategy began to be implemented.

Later, because Huang Da, who developed explosives bags and grenades, joined in, there was obviously not enough manpower, and Shen Li recruited some people to produce explosives together.

With the expansion of the scale, Shen Li found a quiet place in the west of the city as a production base. Speaking of that piece of feng shui treasure land is still the product of the public trial after the attack on Anxi County, originally lived there was a powerful landlord, but unfortunately, after the public trial and sentence, his property was returned to the public, and Shen Li was able to rent it at a low price.

Zhang Guanghua was also quite curious when he heard this, and asked Shen Li what his name was.

"There is a pond there, and it is called 'Turtle Valley' because there was once a thousand-year-old giant tortoise." Shen Li spoke eloquently.

"Poof......" Zhang Guanghua almost squirted out a mouthful of saliva, "It's good, let's call it Turtle Valley." ”

Talking and laughing, it felt like time passed quickly, and after a while, they arrived at their destination. Although Kamegu is said to be a production base, it is actually a larger blacksmith shop and gunpowder workshop, and Zhang Guanghua knew that the parts produced could not be used universally, and the products could not be made into a series. Moreover, the craftsmen are both R&D personnel and production personnel, and the efficiency is not high, to be honest, he is quite disappointed.

However, Carpenter Liu was very interested when he saw Zhang Guanghua coming, and excitedly took out a sample of the arquebus made last night and invited Zhang Guanghua to watch it.

Zhang Guanghua took the silver arquebus in his hand, and his heart was immediately full of surprise, the arquebus was heavy, the barrel was bright, more than a meter long, and the rifling was engraved. The rules of the gun body, the wooden support, the trigger, the primer pot, and the sights are all available, which are no different from those on the drawings.

After Zhang Guanghua took a closer look, Huang Da brought the ammunition bag again, Zhang Guanghua took it and looked at it and was quite satisfied, there were 3 pockets sewn on the cloth bag, respectively, there were lead bullets in the shape of mushroom heads, propellants and ignition powder wrapped in rice paper, and then unpacked, and found that the rice paper was soaked and dried with gunpowder, and the ammunition was granular gunpowder, which helped to burn. It seems that Huang Da has carried out the advice he made to him thoroughly.

"Strategist, I was quite skeptical that you asked me to make gunpowder one by one, but after I tested it myself, I found that the power of this gunpowder has really increased a lot, and now our 'explosive bags' and 'grenades' are all using this kind of gunpowder." Huang Da looked at Zhang Guanghua with a satisfied look on his face, and said quite proudly.

"Hmmm! Huang Da, you are very good! Carpenter Liu, you have also done a good job, thank you for your hard work. ”

Zhang Guanghua, who was getting more and more satisfied, couldn't help but want to shoot a few shots at this time, he was so big, he hadn't touched a gun yet, even if it was an arquebus.

Outside, Zhang Guanghua placed a clay pot in the open space, loaded the ammunition under the guidance of Li Da, compacted it with a whole strip, and then lit the fire rope, opened the fire cover, and raised the gun to aim.

"Bang!" A loud bang was accompanied by smoke, and Zhang Guanghua was choked to tears, this PM2.5 is thicker than in the 21st century. Pressing the lid of the fire, when the smoke cleared, Zhang Guanghua looked into the distance and saw that the clay pot had been torn apart.

After a few more shots, Zhang Guanghua reluctantly returned the gun to Carpenter Liu.

Although Zhang Guanghua was already very satisfied, Carpenter Liu did not get carried away, but said the most fatal problem at present: time-consuming. The barrel alone takes three or four craftsmen to make for several days, and the processing requirements of other parts are very high, and they have to be forged once repeatedly, and the elimination rate is very high.

Zhang Guanghua knows that this is the disadvantage of manual production! It is not a matter of relying on blacksmiths to fight around, it is necessary to make steel first, and then use lathes for assembly line production, otherwise the arquebus cannot be used even if it is designed.

Hearing that Zhang Guanghua was able to produce steel in batches, Shen Li, Carpenter Liu and Huang Da all laughed heartily.

"Why, you still don't believe me?" Zhang Guanghua is very angry, he is a high-achieving engineering student in the new century, and he can't even make steel. After he got a bunch of "bar, la, la", he looked up and wiped it, and there was no one left.

It turned out that Shen Li and they were not interested in this at all, the experience of the old ancestor told them that only a hundred refinements could become steel, so they all dispersed to do their own things, it seemed that they were very satisfied with the current situation, and besides, they were indeed very busy.

There was no way, Zhang Guanghua had to find two blacksmith apprentices who could understand the drawings, if you don't come, brother, I'll come in person! These two people are both apprentices of Carpenter Liu, and their names are Deng Yunfeng and Zhao Hui.

Looking at the drawings of the "Besemer converter" drawn by himself, Zhang Guanghua was quite proud, during this time he ate and lived in the "Turtle Valley", fortunately it was a sunny day during this time, he was able to charge the notebook and copy all the drawings.

"Lao Deng, take a look at this drawing, and if you understand it, find a brick factory and burn this furnace out by burning refractory bricks." After the design is done, hand over the drawings, and someone will naturally be able to help you do the following things, which is good to be a leader!

By the time the converter was built, it was already three days later. Zhang Guanghua supported the converter with a shelf, poured it into it with the molten iron that was ready-made from the blacksmith, and together with Deng Yunfeng and Zhao Hui, he took turns pushing the handle and spinning.

Deng Yunfeng and Zhao Hui looked at the molten iron that was getting faster and redder as the speed became faster and faster, their faces were full of incredulity, and they were almost stunned on the spot. "Could it be that the military advisor knows what kind of witchcraft?" Deng Yunfeng suddenly had this thought in his heart.

Looking at their reactions, Zhang Guanghua was very satisfied. They don't understand it to think it's magical, but in fact, the principle is very simple, and the trick to steelmaking is here. Molten iron is pig iron with high carbon content, and only by reducing the carbon content to 0.2%~1.7% can it become steel. The air that is blown in when the converter rotates just accelerates the oxidation of carbon, and when the carbon is oxidized, a large amount of heat is released, so that a virtuous cycle is formed.

The three of them turned around for half an hour, tired to death, and there were more and more people watching the excitement on the side, Shen Li and Carpenter Liu moved Zhang Mazha by themselves, and sat there while eating melon seeds and admiring it.

Zhang Guanghua didn't know how long it would take, but estimated that the time was almost up, so he poured the molten iron into the mold prepared in advance, which was a batch of molds for big knives, or Zhang Guanghua borrowed it from the government's workshop because of the effect of the test.

Seeing that Zhang Guanghua did not take out the knives to be calcined by the heat, but directly waited for them to cool down, the knowledgeable blacksmiths around him had already begun to point at Zhang Guanghua, in their eyes, the molten iron that missed the best time had been scrapped.

Seeing that Shen Li and Carpenter Liu next to him were still wandering there, Zhang Guanghua was angry.

"Hey! Come and help me sharpen my knives! ”

The two who were chatting happily had no choice, the boss had a black line on his face, so he could only come over to help. As the knife slowly opened, they became more and more surprised, the section of the knife was not gray pig iron, nor black wrought iron, but silvery-white, silvery-white! This means that this is real steel.

After the attack, Shen Li couldn't wait to test the knife, found a small tree, swung the knife down, and cut it off with two knives. It seems that although this knife is a little worse than the steel knife that has been repeatedly calcined, it is more than a grade better than the direct pig iron, and it seems that this steelmaking is already half the success.

The next thing is simple, Zhang Guanghua directly handed over the improvement to Deng Yunfeng.

Looking at Shen Li, who looked incredulous, Zhang Guanghua felt a sense of accomplishment.

Zhang Guanghua, who was in a very good mood at this time, actually had the urge to drink some wine and smoke a little cigarette. So he mysteriously pulled Shen Li, Carpenter Liu, and Huang Da into his room. Since the last time he visited the "Turtle Valley", Zhang Guanghua has moved all his belongings from the county government here, including his "universal backpack".

Watching Zhang Guanghua take out a beautiful big cardboard box and a small golden iron box, the eyes of the three of them were immediately attracted.
