Take the warehouse back to the end of the Ming Dynasty

Chapter 549 Teaching Song Yingxing
After electricity is available, electric motors can be manufactured, and after electric motors are manufactured, air extractors can be manufactured.

Use an air extractor to extract the air in the lampshade. Compared with filling the lampshade with nitrogen, the process of extracting air is much simpler and easier to operate.

When making the lampshade, a thin glass tube can be made on the top of the lampshade, and after the lampshade and the metal base are glued together, the thin glass tube can be connected to the air extractor at that time.

When the air in the lampshade is almost exhausted, burn the thin glass tube at high temperature. When melting, use tweezers and other tools to quickly pinch the thin glass tube to make the holes stick together and seal the opening of the thin glass tube , After the glass is solidified, a relatively vacuum environment is formed.

There is a pointed protrusion at the top of the early incandescent lamp, and this protrusion is the root of the thin glass tube left when the gas is drawn.

The filaments in incandescent lamps are mainly tungsten filaments. Because the early technology is not good, the tungsten filaments are relatively thick and consume more electricity.

However, even so, in today's era, it is an artifact of lighting that far surpasses candles.

Now Zhao Wen's ironworks can also smelt ferrotungsten, so it is not too difficult to make filaments for incandescent lamps.

In Zhao Wen's plan, once incandescent lamps are manufactured, they will be installed throughout Xuan Town.

Except for the streets of Xuanzhen Town, factories, workshops, and ironworks cannot be left behind, and all of them are equipped with incandescent lamps.

Once incandescent lamps and power plants are established, electric lights can be erected along the railway lines so that the trains can run at night.

With electricity and electric motors, electric motors can be used to manufacture more advanced electric lathes.

Although there are lathes driven by steam engines, the power of such lathes is not easy to adjust, the operation is troublesome, and it is difficult to produce high-precision parts.

Electric lathes do not have this problem. The speed of the motor can be controlled by adjusting the current and voltage. Compared with directly adjusting the steam engine, this method is not known how many times simpler.

Zhao Wen looked at the books on the table and kept thinking about these things in his mind.

"My lord, my lord?" Song Yingxing looked at Zhao Wen who was in a daze, and called softly.

Zhao Wen was startled and reacted, "What's wrong?
"My lord, I still have some questions to ask, that's all..."

Song Yingxing hastily wrote down a few questions with a brush on his handbook, and pushed the handbook in front of Zhao Wen.

Zhao Wen picked up the manual, "This problem is easy to solve, mainly..."

In the following period of time, Zhao Wen gave detailed answers to the questions raised by Song Yingxing.

Song Yingxing was like a dry desert, constantly absorbing water.

……

At the same time, Sun Chuanting led a troop to patrol the defense line of the Yellow River Taihang Mountain far away at the junction of Henan and Shanxi.

In today's Taihang Mountain area of ​​the Yellow River, where it borders Henan, Sun Chuanting has built dozens of fortresses, large and small.

In order to build these fortresses, Sun Chuanting reached out to those gentry who had fled from Shanxi.

At the beginning, the gentry from Shanxi ignored Sun Chuanting at all.

In the eyes of these gentry, the matter of resisting Zhao Wen was a matter of Sun Chuanting, a matter of the court, and had nothing to do with them. As for the money for building the fortress defense line, they did not want to pay it at all, and they were not willing to pay it.

But who is Sun Chuanting?In history, Sun Chuanting was able to raise tens of thousands of elite Qin soldiers in Shaanxi without court food and pay, and now he can also get money and troops in Henan without court food and pay.

After Sun Chuanting was stationed in Henan, he took the lead in cleaning up the land of military households in Henan and other places that had been occupied by gentry and powerful.

When clearing these lands, the local gentry were very resentful, but Sun Chuanting had obeyed the imperial decree of Chongzhen, and he also held the Shangfang sword bestowed by Emperor Chongzhen, so he was confident enough to do this kind of thing.

After killing a few gentry who were not long-sighted and made a lot of trouble, the remaining gentry behaved a lot and gave up the land in their hands respectfully.

Of course, Sun Chuanting didn't do anything wrong, he just asked these gentry to hand over the land occupied by military households. Sun Chuanting didn't take care of other occupied land.

Sun Chuanting knew that the land of military households was the limit of these gentry, if there were more, it would probably be counterproductive.

As for the few gentry who were killed, Sun Chuanting did not kill them directly, but labeled them as adulterers with Zhao Wen.

When cleaning up the land of the gentry, local officials in Henan also wrote to impeach Sun Chuanting.

But when the memorial was submitted, it was like a stone falling into the sea, and there was no reply.

They who haven't seen the court's reply for a long time can only watch Sun Chuanting go on like this.

Of course, Chongzhen received the memorials written by these Henan officials. Regarding these memorials, Chongzhen seemed to have not seen them, and let people forget them.

Compared with the Jiangshan Sheji of the Ming Dynasty, these gentry who suffered losses are nothing.

Because military households fled seriously in the late Ming Dynasty, a large part of the returned land had no owners.

For these unowned lands, Sun Chuanting naturally took them into his own hands.

In addition to the land of military households, Sun Chuanting also sent people to develop the wasteland.

Sun Chuanting took out some of these lands and distributed them to local military households.

After the distribution, there was still a lot of land left, so Sun Chuanting recruited the refugees and used the land as a profit to let them join the army.

In this way, Sun Chuanting recruited many soldiers.

Later, there was still a lot of land left.At this time, Sun Chuanting sold the remaining land to the gentry who had fled from Shanxi.

At the beginning, these gentry who fled from Henan were not willing to spend money to buy them at all.

Sun Chuanting knew what these gentry were thinking, so he issued an order saying that gentry who did not have land in Henan could not live in Henan, and if they did not have land, they would be repatriated to their original places.

With an order, these gentry from Shanxi also have to admit defeat and buy land.

By selling land, Sun Chuanting got a lot of money.

It was with these silver coins that Sun Chuanting finally built a large number of fortresses in the Taihang Mountains of the Yellow River in less than a year.

Sun Chuanting led his main barracks to the outside of a city gate called Junsheng Fort.

This Junsheng Fort is a fort built by Sun Chuanting not long ago. The fort is not big, and its circumference is more than 1000 meters. It can store about 400 people inside.

The fortress is a typical square castle, with only two gates in the north and south, and no gates in the east and west directions.

As soon as Sun Chuanting walked to the foot of the Junsheng Fort, the defenders on the top of the city saw Sun Chuanting and others.

"It's my lord, it's my lord supervisor!" A hundred households who were patrolling on the top of the city looked at Sun Chuanting outside the city, shouted, and hurriedly led his men to run down the city.

Not long after, the South City Gate was slowly opened.

The four hundred households in the city rushed out with their personal guards.

"I've seen Master Supervisor!" The four hundred households came to Sun Chuanting who was riding a war horse, and saluted Sun Chuanting respectfully.

Sun Chuanting jumped off the horse and handed the reins to the guards who followed behind him.

"Get up, how is the morale of the soldiers in the city?" Sun Chuanting looked at the four hundred households.

"Return to my lord, the morale of the soldiers in the city is high, my lord, don't worry." The four hundred households shouted in unison as if they had discussed it.

Sun Chuanting nodded, and then walked towards the gate of Junsheng Fort.

When he walked into Junsheng Fort, all the soldiers in Junsheng Fort stood on both sides of the road behind the city gate, welcoming Sun Chuanting.

Sun Chuanting looked at the soldiers in the city and sighed, "With such a strong army, are you still afraid of the Zhao bandits in Xuanzhen?"

"My lord, the strength of the Zhao bandits in Xuanzhen should not be underestimated. The weapons in their hands are really powerful."

At this moment, the former governor of Shanxi, Wu Zhen, followed Sun Chuanting, and a basin of cold water poured down on him.

Wu Tong and Zhao Wenzheng'er had fought each other, so of course he knew Zhao Wen's details. In his opinion, although the Junsheng Fort was well built and there were still more than 400 defenders inside, this Junsheng Fort was under Zhao Wen's control. There, that is, three or five shells.

Sun Chuanting turned around and glared at Wu Tong, "In the future, don't say anything like this to boost other people's ambitions and destroy your own prestige."

Of course, Sun Chuanting knew this fact, but now he was inspecting the military fort, and the morale of the soldiers in the military fort was high. If he said such things at this time, it would have a big blow to the morale of the army.

Wu Xuan hurriedly shut his mouth, followed behind Sun Chuanting, and walked forward.

In the past, Wu Zhen was also the governor of Shanxi at any rate, but since he lost Shanxi, Wu Zhen was deprived of his official position by Chongzhen.

If Sun Chuanting hadn't interceded for Wu Zhen in front of Chongzhen because Wu Zhen and Zhao Wen had personally fought each other and had some experience, it is estimated that Wu Zhen should not be here now, but in the prison of Zhao Prison.

Sun Chuanting led his personal guards and Wu Wei to the wall of Junsheng Fort.

The city wall of Junsheng Fort is not high, that is, six or seven meters, which is as high as a two-story building in later generations.

The city wall is not high, but it is very thick, at least five meters thick.

Although not as strong as Jiancheng, this thickness is already very good for a small Junsheng Fort.

The main structure of the city wall is built with rammed earth and covered with blue bricks.

It's not that Sun Chuanting has never thought of using cement, but the cost of using cement is too high, and since Zhao Wen raised his troops, the transportation of cement and other materials has been banned.

Therefore, Sun Chuanting could only use rammed earth and blue bricks to build the city.

It was Wu Sheng's suggestion to make the city wall like this.

Wu Xuan had faced Zhao Wen's artillery and knew the power of Zhao Wen's artillery, so no matter how high the city wall was, under the attack of Zhao Wen's artillery, it was no different from a small mound of earth.

Although the city walls of Junsheng Fort couldn't withstand Zhao Wen's artillery, castles like Junsheng Fort were spread all over the Yellow River Taihang Mountain defense line.

In Wu Tong's view, the large number of castles can play a lot in slowing down Zhao Wen's marching speed.

Sun Chuanting stood on the gate tower of the city wall to the north, looking to the north.

"The news came from the imperial court before, saying that Zhao Wen had already captured Liaodong. It is estimated that Zhao Wen will launch an attack in a short time, and it should not exceed the spring of next year at the latest. At that time, this place will become a battlefield. "Sun Chuanting looked to the north and sighed.

Wu Xuan stood behind Sun Chuanting, "My lord, it is now November, and it is only three or four months before the spring of next year. During this period, we should step up our defense and transfer all the troops in Henan to the defense line." Come.

If the defense line cannot be defended, no matter how many soldiers and horses stay in Henan, it will be of no use.There are also these vassal kings in Henan, Zhou Wang, Tang Wang, Fu Wang, Lu Wang, etc., and they have to pay people and money. If the defense line cannot be defended, their property will become Zhao thieves.

At that time, King Jin's lineage was unwilling to give money, so what happened?As a result, none of them escaped, and they were all picked up by Thief Zhao. "

"The king of Zhou and the king of Tang can be better. After the official stationed in Henan, these two princes have provided food and silver to the official, but King Fu and King Lu are a little ignorant.

Especially this Prince Fu, I once sent envoys to the Prince Fu's Mansion. Originally, I was wondering if King Fu could provide some food, grass and silver, but I didn't expect that the envoys I sent out were blasted out without even entering the gate of the Prince's Mansion. . "Sun Chuanting let out a long breath, with a look of helplessness on his face.

The king of Zhou is quite good, he is more concerned about the affairs of the court, and he can give up his own family property, unlike other vassal kings who have nothing to do with themselves.

The first king of Zhou was Zhu Huan, the fifth and fifth son of Zhu Yuanzhang. In Hongwu's third year, he was named King of Wu. In Hongwu's 11th year, he was named Zhouwang. The first vassal king in Henan.

The lineage of the King of Zhou was thriving. By the end of the Ming Dynasty, more than half of the entire Kaifeng city was owned by the King of Zhou.If these descendants of King Zhou are concrete, they can form an army.

At the end of the Ming Dynasty, Li Zicheng surrounded Kaifeng. The last king of Zhou, Zhu Gongfu, went bankrupt to support the government and army against Li Zicheng.

The water of the Yellow River poured into Kaifeng Mansion, and Kaifeng Mansion was completely flooded in an instant.

Almost all of Zhou’s lineage died in the flood of the Yellow River, and Kaifeng was submerged. Zhu Gongyun escaped by chance and fled to Anyang, where he died in the 17th year of Chongzhen.

The three sons of Tang Wang Zhu Gong and Zhu Yuanzhang's No.20 were born in Hongwu in 19 years. In Hongwu's 24 years, he was granted the title of Tang Wang and Nanyang, Henan Province.

Tang princes in later generations had few heirs, and several had no children. The eighth Tang king Zhu Shuoyin had the most sons, and he gave birth to 11 sons.

Generally speaking, Tang Wang's family lived in Anyang, Henan Province in good weather, without any bright spots or faults. They were also friendly to the local people, and there were not many things that oppressed the people.
