Luo Wen only stayed in Mengjiazhuang for a while, and then hurried back to his hometown in Jingle County.

His father and mother haven't seen him for a while, so he has to take the silver back to buy a big yard, and then buy a lot of New Year's goods to go back to honor the two old people.

Qin Chuan didn't let him move over, because the two shops in Jingle County still had to rely on him to take care of them, as well as outside businesses, such as selling pig iron, buying cotton, salt, bronze brass, lead, cowhide and sheepskin and other skins.

The two iron ore mines of Montenegro and Hongli Mountain have very little associated copper and lead and tin, and they are difficult to refine, whether it is to manufacture flintlock pistols or artillery in batches, they are inseparable from various copper workpieces, and bullets and shells are all lead, so these two things have to be purchased in large quantities.

Not to mention salt and cotton, the former has to be eaten every time, cotton can be used to weave cloth and sew clothes, but also to make cotton armor.

Qin Chuan wants every soldier in his army to wear at least one piece of cotton armor, and when he queues up to shoot with a flintlock pistol, he has to be able to withstand the long-range projectile of the opponent's bow and arrow, the price is low, and the cotton armor that is easy to make is undoubtedly the best choice.

Javelin cavalry should be equipped with a layer of cotton armor and a layer of cloth iron armor, or directly on the composite armor, and the horses should also try to wear armor to withstand the enemy's long-range attacks when attacking.

As for sheepskin cowhide and other skins, they should not only be used to make leather armor, boots and fur coats, but also to be used for flintlock pistols and artillery firing, of course, it can also be replaced by linen, but it is better to use skin, and the lead of the flintlock pistol is best wrapped in deerskin soaked in tung oil, because the deerskin is soft, elastic, faster to load, and increases air tightness.

The Franc cannon that is ready to be cast should also be covered with a sheepskin at the mouth of the sub-gun, because the Franc cannon has a fatal shortcoming, poor air tightness, and the docking between the sub-gun and the female gun is not tight, which is easy to leak, resulting in a reduction in the firing range, and in serious cases, it will cause a bore.

Qinchuan designed and improved Franc cannons, will cover the mouth of the sub-gun with a circle of sheepskin, and then stuff it into the mother gun, when the cannon is fired, the sheepskin is heated and expanded, blocking the gap between the child gun and the mother gun, increasing the air tightness, thereby increasing the firing range, and reducing the risk of exploding.

The pasture grass in the area of Luliang Mountain is abundant, and there were originally many herdsmen grazing, but now it is rampant, and most of the cattle, sheep and horses raised by the herdsmen will be plundered by horse bandits and bandits, coupled with the exploitation of the government, resulting in nine out of ten herdsmen not surviving, and they have all gone to be homeless, and there are very few herdsmen who remain here to graze.

Therefore, the skins should also be purchased in large quantities.

The business business will be left to Rowan.

Although this guy was beaten up and cried a few times ago, he reminded Lao Huang loudly at the turn of his head, which proved that he was not too cowardly, and he was trustworthy.

……

Luo Wen left the second, Liu Youzhu and Li Dingliang sent people back from Yongning Prefecture and Taiyuan to report that one of them was trapped by the heavy snow on the way, fortunately Liu Youzhu bought dozens of carts of cotton and cotton cloth, when he was trapped, he couldn't take care of much, and directly lent cotton and cotton cloth to the hungry people to keep out the cold, so he barely withstood it, but among the nearly 2,000 hungry people, more than 100 people still froze to death.

Li Dingliang also stayed in Taiyuan because of the heavy snow blocking the mountain, he brought two hundred Guan imperial troops and one hundred stone of grain, and took in a thousand hungry people, because of the large number, soon attracted the attention of the Taiyuan city army and the Ninghua royal palace.

King Ninghua took the only hundred or so guards left in the palace, and received three hundred guards from the Jin Palace, and surrounded Li Dingliang.

When the two sides were tense and ready to fight, Du Yingtang hurried over and stopped the guards of the palace with a smiling face, which prevented the two sides from meeting each other.

But Du Yingtang was slapped twice by King Ninghua, so loud that he could hear it from across the street.

Li Dingliang also swaggered to buy a thousand catties of vinegar from Ninghua Wangfu, this vinegar is brewed by the Wangfu workshop, and it is very famous in this area, if it is not for the lack of stock in the store, he also wants to buy more back, and the silver will be earned by Ninghua Wang, and the big steward can eat a good meal of vinegar is a big deal.

……

Qin Chuan found that he had broken his promise.

After his triumphant return, he went to the Wen family in Fenzhou to ask for marriage, but he found that he couldn't leave at all.

The snow covered the mountain, and although Lou Fu ushered in a rare calm, his things were one after another.

The manufacture of cannons and guns is still ongoing, and Wang Jizong's school is about to open, except for the craftsmen of the gun factory, the gun factory and the gunpowder factory, all the literate people in Lou Fu have been temporarily transferred by him to copy books, that is, to copy the textbooks he compiled.

Qin Chuan also participated in the compilation, and finally formed three disciplines, one is to cut out the cumbersome and useless eight-strand literature and other things, and finally come up with traditional Chinese studies that are similar to modern language and morality.

The second is arithmetic, which is not an independent discipline today, Qin Chuan not only separates it from the scriptures, but also compulsorily requires the study of Arabic numerals.

In fact, Arabic numerals were introduced to China as early as the Yuan Dynasty, but at that time there was a convenient thing called chips in China, so it was not promoted.

The third discipline is the sciences that encompass nature, physics, chemistry and biology.

This science is the one that Qin Chuan attaches the most importance to, because it can open people's brains and make ignorant people full of curiosity.

Only with intellectual curiosity can you really learn something.

These three disciplines are still very imperfect, the first two are in charge of Wang Jizong, he invited three friends from Jingle and Taiyuan, the kind of depressed poor scholars, and invited Song Zhiting back, several people to improve the teaching materials together, and from the literate villagers, selected fifty people, ready for unified training, and selected some of them to become Mr. Teaching.

The third science can only be perfected by Qin Chuan himself, which is precisely compiled.

Qin Chuan has been locking himself in his office, racking his brains to recall and write down the basic knowledge of nature, physics, chemistry and biology that he has learned, and he doesn't know how many quills he has bitten.

After Wang Jizong and others read what he wrote, they were shocked one by one, these things were too subtle and mysterious for them.

For these sources of knowledge that came out of nothing, Qin Chuan's explanation is: I am a foreign scholar from the Ten Continents who has been ignited by the fox immortals.

Wang Jizong and others naturally knew each other very well and did not go to the bottom of it.

In addition to compiling science textbooks, Qin Chuan was also busy with another thing: lecturing martial arts.

He wanted to set up a martial arts hall and mass-produce middle and low-level officers.

Morale is the soul of the army, and officers are the providers and maintainers of morale.

In addition to the personal charm of the generals and the spirit of the family and country, the middle- and low-level officers are the foundation for maintaining and even improving morale.

Luo Daniu, Zhao Wu, Liao Sangun, Luo Ba, Huang Liuxi, and even Lao Huang and Bobcat and others have recently gathered in a courtyard specially arranged for them by Qin Chuan and quarreled to discuss the teaching of the art of war in the martial arts hall, arrange the troops, and so on.

Among these shortcomings, only Zhao Wu is literate, but each of them has their own battle formation and fighting experience, so Qin Chuan let them quarrel, and when Liu Youzhu and Li Dingliang come back, these two people will have to join in and quarrel together.

For the teaching materials of the martial arts, Qin Chuan plans to focus on the three books of "Sun Tzu's Art of War", "The New Book of Discipline and Effectiveness" and "Actual Records of Military Training", and other "such as Sun Bin's Art of War", "Liutao", "Sima Law", "Taibai Yin Jing", etc., will also be taught, but only to learn from each other's strengths and weaknesses as auxiliary textbooks.

When the Shentai Peak Dazhai was laid, a copy of "The Art of War" and a "New Book of Discipline and Effectiveness" were searched from inside, and a copy of "Records of Military Training" was also found in Du's house, and the main teaching materials were just ready.

Qin Chuan also asked Li Dingliang and Liu Youzhu to buy military books and other books outside, and bought everything they could buy, and then screened them when the time came.

Education is a complex and huge project, which made Qin Chuan dizzy every day at the beginning, and it was more tiring than rushing to the outside of the fortress.

When he was too tired, he went to the gun factory and the gun factory, and also went to find Zhao Mancai, this guy has now opened two boiling pots, and the people who went out to look for caves have also returned, and there are dozens of caves with a lot of nitrate in the area of Guandi Mountain.

Cave nitrate is a renewable resource, and after it is taken, it can be regenerated in about two years, and it can be completely self-sufficient.

……

Li Dingliang and Liu Youzhu returned, bringing back nearly 3,000 hungry people and placing them in thatched huts and underground nests prepared in advance.

Now Lou Fu has a population of 8,000, not counting the 3,000 people in the two mines, which can be regarded as a big town in the current era.

The town is digging ground and building houses day and night, and when the spring of the next year begins, it will move 30% of the population to settle in Jingyou Town.

Li Dingliang and the others bought back a large amount of cotton, as well as a lot of skins, brass, lead, salt, books, wine, vinegar and other messy things.

All the women are weaving cloth day and night, and some villagers are washing cotton and making cotton nails.

There are also 1,000 selected villagers, as a militia in reserve, who are practicing daily under the leadership of Luo Daniu and other Rao, and after spring ploughing next year, some of them will be incorporated into the Guan Emperor Army.

All the imperial troops practiced day and night, and a small number of them had already begun to practice holding guns and shooting in formations, or went to artillery factories to receive artillery training, in preparation for the coming era of firearms.

The whole Lou Fu was in a hot place, but it spent a period of time in an orderly manner.

The days in the calm passed quickly, and the end of the year was approached in the blink of an eye.

is about to enter Chongzhen for six years.
