After the loss of Tieling, the predatory policies of the Houjin near Tieling produced a large number of new displaced people. Pen ~ Fun ~ Pavilion www.biquge.info A few months ago, the intensive construction wave in Fushun created a large number of employment opportunities, and under the word of mouth, the people of Tieling flocked to Fushun one after another. The city wall repair project led by Xiao Ji, the prefect of the same government, and the reconstruction plan of the damaged roads in the city absorbed a lot of displaced labor.

More displaced people, selected by the Shen Jia militia, were engaged in coal mining, quarrying, farmland and water conservancy construction, as well as carpentry, mechanical gears and smelting manufacturing. It is a good thing to have manpower, especially in places like Guanwai, where there are many displaced people, and the cost of manpower is very low. During the year, Shen Jia could rely on Fushun City's military rations to complete most of the work. Next year, Shen Jia will have to consider self-financing, and at the same time, he will also need to provide some ordnance support to Chen Ce and He Shixian.

Fortunately, Chen Ce is a reasonable person, he is quite convinced of Shen Jia's organizational ability, and he also knows the truth that he must take it in advance and must deal with it first. On the issue of grain withdrawal, Chen Ce was extremely open-minded, but it was He Shixian, who couldn't guess what Shen Jia's purpose was, and nagged from time to time.

When cement is manufactured, it is necessary to crush stones and sift them, which is a very labor-intensive thing, a large number of cattle and mules are requisitioned and purchased, which are used to drag stone grinders and grind broken stones, and there are many workers, wielding sledgehammers to strike, and the whole gravel yard is tinkling everywhere. Shen Jia misses the power of the twentieth century very much, but now, he can't even get the simplest Newcomen steam engine. Just now, in the first steam engine model experiment designed by the mechanical group, a craftsman was burned by steam halfway because of air tightness problems. Although the person in charge, Liu Jin, continued to supervise the experiment, the final result was still disappointing. The piston in the cylinder was motionless and did not generate any power.

Liu Jin was a well-known handyman who worked as a carpenter, mason, and blacksmith. Once, when Shen Jia passed by the mechanical group, he was surprised to see him assemble several wooden gear models into transmission devices in different directions, so he personally nominated him as the chief designer of the steam engine. Liu Jin is thirty-five years old, and even in the face of great glory, he is still a little restrained and uneasy. It wasn't until Shen Jia stuffed a token of appointment into his hand that Liu Jin confirmed that he was not dreaming.

After that, Liu Jin was full of enthusiasm in his work, although he did not understand the steam engine, but he studied the design principles and drawings of Nukomen given to him by Wen Qing like a stream. Shen Jia once believed that he had found the right person. But two months later, the first simple steam model experiment failed, Shen Jia was pondering, Liu Jin was a little uneasy, he tried to explain, but he was a little cringe. After a while, it was Shen Jia who said that Liu Jin was not to blame for this. After waiting for a long time, Shen Jia's brows slowly relaxed, and he felt that he was in a bit of a hurry, after all, the days of coming to this time and space were not long.

"Liu Jin, you check again, maybe the piston is not airtight enough, so that the steam can't push the piston to move, maybe you can try to wrap the piston in linen."

"Lord Shen, the villain thinks so too, I'll go get it, if it's fast, maybe there will be results tomorrow."

Sun Yuanhua on the side was quite surprised by Shen Jia's idea, and he felt that Shen Jia's theory of using steam to open the teapot lid was a bit specious. However, the long-term study of the West and the East made him curious about new things, so he decided to observe for a while.

"Shen Shinephew, Fushun currently only has four old guns, future defense, insufficient firepower, when Xu Shi was training in Tongzhou, he also said that artillery is a sharp weapon in the army, and it is indispensable. In the past few days, I have seen a lot of workshops in Fushun, and the facilities are neat, anyway, I have nothing to do, why don't I help you make some artillery? ”

"Uncle Sun, it's not that I don't want to, first, I don't have money now, I can't afford to buy so much copper, and I think the top priority is smelting, in my hometown, my musket barrel can withstand tens of thousands of continuous shots, and there is no danger of exploding, but the musket of the Ming Dynasty, not to mention the new gunpowder, is black powder, and the explosion rate is very high. If the iron-smelting industry is upgraded, artillery can be made of steel, and the cost will be reduced a lot, Uncle Sun, what do you think? ”

"It's a pity that I don't know anything about iron smelting, otherwise I can help Shen Shi's nephew."

"Uncle Sun, as long as you stay in Fushun, it will be my greatest help, Uncle Sun might as well let Master Xu do activities and help you get an official position in Fushun. I also have some ideas about iron smelting, and I plan to build a few coke kilns in the south of the city to make coke from coal from the Fushun area, which is an important condition for smelting high-quality steel. ”

Sun Yuanhua didn't understand the coke mentioned by Shen Jia, he asked with interest about the principle of coke generation, and Shen Jia explained the general process of blast furnace steelmaking and coke extraction from beginning to end. Shen Jia complained that the blast that relied on manpower and animal power could no longer meet the needs of blast furnace steelmaking, and without a blower, the furnace temperature could not rise.

Sun Yuanhua smiled at this and said: "Nephew, I see that there are already several windmills in the south of the city, if the steelmaking furnace is placed outside the city and relies on the power of the windmills, it should not be difficult to blow the wind, and with the help of the hydraulic stone mill of the surrounding rivers, it can also solve part of the power, of course, don't think about it in winter outside the gate, the river is frozen." ”

Shen Jia lowered his head and thought about it, feeling that there seemed to be some truth. When the power of the windmill is unstable, it can be supplemented with animal power, which can solve part of the problem, and the hydraulic mill can also be used as a supplement.

"Thank you Uncle Sun, I can find someone to try this, as long as we can make a good furnace of steel, this can solve our biggest headache."

Sun Yuanhua is a relatively timid person, but this cowardice reveals a persistence, persistence for the future. Sun Yuanhua had been exposed to some Western basic sciences, coupled with Confucianism, he understood better than anyone else the destructive power of Jiannu on the other side. Armed with bows and crossbows, Jiannu burst into the city, and in their eyes there was only a distinction between a slave and a dead man, civilization, inheritance and culture, at least for the time being. This is also the reason why Sun Ruhua and Xu Guangqi are worried about current affairs.

After the Battle of Salhu, Xu Guangqi even supervised the training of the new army in Tongzhou, but the supply of military salaries and equipment was difficult, and the training plan was not smooth. During the late Ming Dynasty, Xu Guangqi and Sun Ruhua were outliers, they were baptized by the Western Church, and it was actually difficult for them to integrate into the entire court. Since then, the two have had ups and downs, and have never been accepted by the mainstream of the DPRK and China.

"Uncle Sun, when you came into contact with the Taixi Church, did you hear of thermometers?"

"Oh, I didn't pay attention to this, if you need it urgently, I'll send someone to the church to ask."

Although the Chinese have rumors about thermometer design in history, Shen Jia's existing data are all based on Western measurements, and considering the compatibility details and time cost, Shen Jia still considered asking the church for help. The world's first clearly documented thermometer was invented by the Italian scientist Galileo in 1593. During the Shunzhi period of the Qing Dynasty, the Belgian missionary Nan Huairen first introduced the concept of Western thermometers to China.

However, Shen Jia obviously did not intend to wait any longer. Gasoline can be extracted at a temperature of about 90 degrees Celsius, which is easy to do by controlling the water temperature. However, for kerosene and diesel distillation, the temperature should be controlled between 200 degrees and 350 degrees, and it is difficult to control without a thermometer and relying only on the experience of workers. Everyone knows that Pan Technology has a high income, but the premise is that the resources must be in their own hands. After thousands of years of precipitation in the development of human science and industrial technology, it is difficult to imagine how difficult it is to cross an era with only a few drawings of Shen Jia.

Returning to the city and bidding farewell to Sun Yuanhua, Shen Jia came to Daying. According to yesterday's request, Shen Jia formed an engineer company, which was mainly used to build bridges, open roads, build command posts, and ensure the smooth march of the troops. The inclusion of the engineer as an independent branch of the army was a new thing for the Ming army. Most of the Ming army counted sappers as auxiliaries, or craftsmen with the battalion. Shen Jia put it forward for the first time, and everyone in the group was curious. Under the recommendation of everyone, Shen Jia appointed Wu Huayong as the commander of the engineer company. Wu Huayong was born in a family of carpenters and has a certain understanding of bridge building. Shen Jia drew another hundred Ming soldiers with similar experience in the team and established an independent engineer company.

As expected, Zu Ming, the commander of the veteran company, was defeated, and he didn't even get a squad leader. In the evening, Zhao Changshun, who was out on a mission, suddenly returned to Fushun ahead of schedule. Seeing Zhao Changshun for the first time, Shen Jia felt that something was wrong.

Zhao Changshun and the two recruit company commanders were summoned to the camp tent, and Shen Jia cast an inquiring look.

"Instructor Shen, we lost eight brothers on this outing!"

Shen Jia was suddenly startled, and hurriedly asked, "What's going on, you tell me the process in detail." ”

"Last time we found a few ships, crossed Sarhu, touched the vicinity of Sarhu City, and raided a few outposts to gain a lot. This time, I took two companies with me and wanted to go to the Boundary Domain City to have a look. We followed the trail east and arrived near the Boundary Domain. It is heavily guarded and faces water on three sides, making it difficult to get in. In desperation, we had no choice but to return. Who knew that there were a few sentry posts on the road, and everyone felt that they would come out and go back without taking a few heads, for fear of being laughed at. So we raided three sentry posts the night before. When I returned yesterday, I didn't want to encounter an ambush, but fortunately, with grenades, everyone rushed out, and in the process of charging, eight brothers died. ”

"Didn't you investigate beforehand? How did you fall into the ambush of the other party? ”

"At that time, we rode for four hours, and we had already thrown the Tartars far behind us, and after a few months of constant harassment, the Tartar activities on the north shore had subsided a lot, so the warriors relaxed their vigilance." After speaking, Zhao Changshun lowered his head in shame.

"I think you've been fighting a lot lately, your vigilance has decreased, and people have become proud, haven't you? The Tartars live by fishing and hunting, and once they get the news, it should not be difficult to take a boat from Sarhu City to cross the lake several miles wide. What I told you when I was training before, it's only been a month and a half, and you've taken my words as a deaf ear. Shen Jia stopped talking and glared at Zhao Changshun fiercely.

"This time, the death notices of the eight soldiers will be delivered to their homes by you personally, and tomorrow you will be confined for a day, so you can think about it. Let's get out, all the companies are re-electing the company platoon leaders, and you are the same, go to Liu Wencai, and he will tell you what to do. ”

"Yes, Instructor Shen!" The three of them saluted solemnly, and then went out of the account in turn.

"Zhao Changshun, you're back!"

Zhao Changshun returned to the camp, he blamed himself for his mistakes and was listless.

"A mistake to make yourself like this, if I were a slave, I would definitely hide in the quilt and laugh, can you fucking cheer up, there is always a reason for everything, go back and write a summary report, and then summarize the gains and losses in detail in front of a group, what happened to the other letter?"

Hearing Shen Jia ask about the letter, Zhao Changshun said with relief: "This letter is very strange, it was received when we first dressed up as a city merchant and went to Nanzamu. I was mixed in with a group of merchants, and I happened to be in the town when I was confronted by a group of Tartars, led by a centurion or something, and I received the letter shortly after the Tartars let me go. ”

"Who else was with you?"

Zhao Changshun thought for a while and said: "There is also Liu Heizi, he is clever, trains hard, and has some strength. ”

With Zhao Changshun's description, Shen Jia's impression of Liu Heizi quickly emerged in his mind.

"You must have been exposed at the time, otherwise this letter would not have been delivered to me, can you still remember the appearance of the person who sent the letter?"

"It's a boy begging on the street, and he said someone gave him a few pennies to deliver this letter to you."

Shen Jia fell into deep thought, obviously the other party already knew Zhao Changshun's identity, but the other party did not reveal it, maybe he was waiting for something. Seeing Instructor Shen thinking about something, Zhao Changshun quietly retreated.

When he returned home at dinner, Shen Jia frowned and thought hard, even the meals cooked by Qu Xiaoyi and Wu Shihan were tasteless. Seeing that Shen Jia seemed to be worried, Wu Shihan quietly asked: "Brother Shen, now that the business of Jiahe Fang is booming day by day, even the daily military supplies of the garrison are purchased from the Fang, you should be happy, why have you been worried in the past two days." ”

Shen Jia smiled bitterly, gently pinched Wu Shihan and said, "I'm fine, don't worry about me." ”

Qu Xiaoyi on the side heard Shen Jia's comfort, but was a little uneasy, the more Shen Jia was like this, the more she felt that there was something strange in it.
