On the 25th day of the first lunar month of the sixth year of Chongzhen, a good news was sent from Zhangjiakou Fort of Xuanfu and sent to the capital.

The general content is: about 200 Dongliu pretended to be a merchant in the Ming Dynasty and wanted to sneak into Zhangjiakou Fort to make a mistake. It happened that Wang Kun, the military supervisor of Xuanzhen, patrolled Zhangjiakou Fort, used his fiery eyes to see through the tricks of the Dongliu, and used the Zhangjiakou Fort to defeat the enemy and killed 154.

Following the victory, there were also one hundred and fifty-four Jiannu heads, and they rushed to the capital with a quick horse.

As those heads and good news were delivered, the officialdoms in Xuan, Da and Jinsan gradually calmed down and returned to their previous peace.

But these officials had a joke after dinner, that is: all Qianhu, Ninghua, who did not know the high ground, threatened to start a massacre in the three towns of Xuandajin.

Whenever they talk about this, the officials in the three towns laughed loudly.

So what if you make a few great achievements? So what if you are valued by the emperor? So what if you hold the seal of General Wude? So what if you hold it?

But can he still make a fortune in a thousand households?

Including Shanxi officials who heard the phrase "killing" with their own ears that day, they only thought it was a joke.

The Qin surnamed Qin thought that he could still get away with the law after winning several battles and tied up several big families. Can he do whatever he wants?

I just didn't bother to pay attention to him and let him jump around in the remote village of Loufan.

He has few good days.

In the entire Shanxi officialdom, only a few of them, including Xu Dingchen, Du Yingtang, etc., realized the seriousness of the situation.

However, they followed the principle that it was better to have less than more things. The heads and prisoners were sent to Xuanfu and ignored them. When Zhangjiakou Fort transferred the heads to the capital, they did not seek any benefits.

Anyway, I just watch the sideliness and protect myself.

...

Qin Chuan was able to walk freely. Although his chest still felt a little painful from time to time, as long as he did not exercise vigorously for the time being, it would be fine.

A total of 78 people were killed in battle on the spot and seriously injured and dying attendants in red. Qin Chuan was able to walk freely and buried these guards until death.

Luo Daniu selected two hundred Guandi Army in advance. Qin Chuan only picked a part of them and formed a new hundred-man guard with the surviving personal guards. The number was still in red-robed attendants, and these hundred people were still wearing red armor and red cloaks.

In Luo Ao's words, if you see Hong once, it will be fine in the future.

After the disaster, Qin Chuan realized that Loufan's sentry system was too weak.

Fortunately, Huang Erdan reported this time, which made him and the red-clothed servants mentally prepared, and also gave Chen Zhan and the villagers enough time to escape.

If Huang Erdan had not been able to, a hundred red-clothed servants would have been caught off guard by the two hundred Jiannu and then wiped out the entire army, and he would have died.

So, we have to strengthen the whistle.

You can no longer let any cats and dogs come in, threatening Lou Fan's life.

The first thing he did when he woke up was to let someone travel along Loufan and Jing twenty miles away to build more than ten posters, each poster was stationed by three posters, and shifts were changed every three days. The poster was prepared for firewood that had been mixed with cow dung and horse manure, and once the enemy was discovered, smoke would be set off.

Then, he organized more than 500 militias into the Guandi Army, allowing the regular troops to reach 2,000.

The camp was still the same ones, first climbing the camp, trapping the camp, Wudang camp, Shifang camp, Tiger and Leopard camp, and his guards' red-clothed attendants.

Among them, the camp first, the camp and the Shifang Battalion have sent one flag of troops to the gun factory and the artillery factory in turn to practice the use of artillery and flintlock guns.

When the three camps will first equip firearms.

During Qin Chuan's recovery period, new breakthroughs have been made in iron smelting and firearm manufacturing. Yan Sanqi improved the crucible and blower system based on the ideas given by Qin Chuan.

The original open crucible was changed to a semi-closed crucible, leaving only three holes, one for limestone and sticks to stir, the other for blowing air, and the last one is the hole for inlet molten iron. After the molten iron is injected into the crucible, the hole will be sealed to reduce heat leakage.

This crucible is similar to the reflectors that appeared in Europe in the 18th century. It allows heat to constantly reflect in the closed crucible, thereby maintaining or even increasing the temperature in the crucible, allowing the molten iron to always smel in high temperature liquid state and eliminating impurities.

Qin Chuan estimated that the pig iron made with this method is very close to the low carbon steel in later generations.

So he immediately asked the two mines in Heishan and Hongqishan to build secondary refining furnaces, and use this method to smelify iron.

With good iron, everything will be easy to do.

Chen Zhan built two more six-pound cannons, one of which was made according to the previous iron mold preheating and central water cooling method. Due to the insufficient furnace temperature, the gray iron cannon barrel was still not obtained. However, the performance was good after annealing. When the gun was tested with double and triple-speed fire medicine, there was no blow-off or cracks, thus obtaining a finished cannon next to it.

The second door is to cast the white-mouth iron cannon tube according to Qin Chuan's method, and anneale it in a closed heating furnace. The barrel is filled with toner, leaving a gap, and use a copper tube to inject air into the barrel so that the toner can be sufficient, and then carburize and anneale the inner chamber.

After completion, Qin Chuan was surprised to find that the performance of this gun was better than the first one. It should be that the barrel was annealed and successfully obtained black-hearted forged cast iron. Moreover, after the inner chamber was hollow carburized and nitrided, its strength and impact resistance were greatly improved.

Therefore, Qin Chuan asked the artillery factory to use this method to cast cannons, first build tiger squat cannons and Franc machine cannons, and try to make thirty doors before the spring snow melts.

Because in the short term, the enemies he faces can be solved with these two types of artillery.

As for the six-pound cannon, there are two of them now, which is enough for the time being.

Qin Chuan officially named the six-pound cannon red-clothed six-pound cannon, one to commemorate the red-clothed attendant who died in battle, and the other to confuse the public and make others think that his cannon was the red cannon.

Qin Chuan was also very pleased with the progress of the gun factory. Li Xuejing had assembled fifty boring machines and made thirty qualified flintlock rifles and twenty scrapped barrels.

In other words, the yield rate of gun factories can reach 60%, which is about twice the yield rate of bird guns made by the Ming court's military weapons bureau or other local troops.

Qin Chuan gave Li Xuejing a new task: to make a boring machine for rifling.

It is unrealistic to mass-produce rifles, but he can start researching rifles while mass-producing smoothbore flintlocks.

The point is how to rifle.

With the current technical level, it is possible to manufacture several rifled rifles, but if you want to mass-produce, you must develop a set of rifled boring machines with extremely high accuracy.

This thing cannot be found in just a few months. If you want to make a large number of boring machines with uniform specifications and precision, you will not be able to handle it in just one year.

Qin Chuan still has time. Now, there are still a few years before Li Hongji and Zhang Bingzhong rise and the Later Jin has the strength to enter the Central Plains.

...

Before Qin Chuan's injuries healed, he gave him a reward, and he wrote a letter, two sets of official uniforms, one set of regular uniforms, one set of public uniforms, and one set of goose feather sword given by the emperor.

He was used to using the long sword, so the goose-feathered sword was thrown into the arsenal.

Those two sets of official uniforms were worn, and they were still wearing them on their bodies and inspecting Loufan in a swagger.

The villagers I met along the way respectfully called "Master Qin".

Compared with the previous hundred households, his current fifth-rank 1,000 households are also considered a worthy adult.

...

On the second day of the second month of the sixth year of Chongzhen, the dragon raised its head.

Early in the morning, Qin Chuan, a well-injured person, led a hundred red-robed servants, Luo Daniu and 200 first to the camp, held high the "Qin" flag, and headed north to the north.

He went to Ninghua Guard Thousand Houses Institute to take office.

Ninghua Institute is located between Jingle County and Ningwuguan, 80 miles away from the county seat and less than 90 miles away from Ningwuguan. The strategic location is very important.

As long as Qin Chuan controls this thousand-household office, he can sandwich Jingle County in the middle, and it will not take long to control the entire Jingle.

Then we control Ningwu Pass and Lan County. Jieshi, the entire hinterland of Luliang Mountain was in his hands.

Now that he is angry, he has already shown signs of warming up. He will first go to Qianhu House in Ninghua to live in one or two, and then go to Fenzhou to propose marriage with his father-in-law.
