Take the warehouse back to the end of the Ming Dynasty
Chapter 624 Successful Manufacturing of Electric Lamps
Chapter 624 Successful Manufacturing of Electric Lamps
Zhao Wen rode on a war horse, leading the soldiers and horses under his command to gallop non-stop towards Kaifeng Mansion.
The horseshoes of the war horse stepped on the wilderness, and the green grass on the wilderness was trampled into the soil by the war horse.
The morning sun was not so dazzling. Under the morning breeze, Zhao Wen's army marched in the wilderness.
"My lord, General Song sent a messenger over just now. He said that there are some defenders in Xingyang, and there are still many people in the city, but the gentry and officials were almost taken away by Sun Chuanting.
At the same time, the people in the city have been hungry for a long time.The food in the city was either taken away by Sun Chuanting or burned by Sun Chuanting.
At noon yesterday, Xingyang had been captured by General Song.Xingyang has now fallen into our hands. The defenders in Xingyang City have been captured by General Song, leaving about fifty people to guard these prisoners.
In order to stabilize the hearts of the people in the city, General Song kept a part of the military rations in his hands. "
Li Xiaosan followed Zhao Wen, speaking word by word.
Looking at the wilderness ahead, Zhao Wen said calmly, "I thought Sun Chuanting was planning to drive away all the defenders and civilians in all the county towns, but I didn't expect to keep some."
"My lord, it may be that Sun Chuanting feels that these people cannot be let go in Kaifeng Prefecture." Li Xiaosan said.
"Okay, let's not talk about this, and order the whole army to speed up."
After Zhao Wen finished speaking, he flicked the whip in his hand and controlled the horse to move forward.
The distance between Zhao Wen and Xingyang was getting shorter and shorter. At noon, Zhao Wen finally arrived in Xingyang.
Zhao Wen looked at Xingyang City in front of him, and rode forward on his horse.
The defenders left by Song Hu on the top of the city saw Zhao Wen's banner, jumped down from the city wall and opened the city gate.
After a while, Zhao Wen's army entered Xingyang City.
Zhao Wen rode on a war horse and shuttled through the streets of the city.
A large number of people gathered on both sides of the street. These people looked at Zhao Wen and Zhao Wen's soldiers and horses with panic on their faces.
If Song Hu hadn't given them some food before, I'm afraid these people would have gone to nowhere when they saw Zhao Wen.
The people on both sides of the street were in ragged clothes, and their clothes were so dark that they couldn't see their original appearance.
The faces of the people in the city are covered with dirt, and the hair on their heads is filthy and dusty, with lice and fleas dancing on them.
There are countless fertile fields in Henan. In the early days of the founding of the Ming Dynasty, the people lived in peace.
But as the number of vassal kings and gentry increased, the land in the hands of Henan people became less and less.
In this era of lack of pesticides and fertilizers, if you want to feed a family, you must cultivate a lot of land.
And the land in the hands of the people was taken away by the vassal kings and gentry, so it was not so easy to have a full stomach.
"I have seen Mr. Chief Soldier!"
A general with the appearance of a hundred households appeared in front of Zhao Wen. He looked at Zhao Wen who was slowly approaching, saluted hurriedly, and then greeted him.
"My lord, in the past few days we have counted the number of people in the county, and there are almost 2 people, men, women, old and young.
But all the food in the city was taken away by Sun Chuanting before, and the city has been out of food for several days.
It is estimated that the food sent by General Song will not last for a few days. "
The hundred households walked to Zhao Wen's side, looked at Zhao Wen on the horse, and said.
Zhao Wen didn't answer, but looked at Li Xiaosan, "Let the army speed up, and let the soldiers and horses escorting Zizhong's grain and grass enter the city quickly. After entering the city, take out some of the grain we seized from King Fu and distribute it To the people of Xingyang."
Li Xiaosan hurriedly followed Zhao Wen's order.
After half an hour, all Zhao Wen's soldiers and horses entered Xingyang City.
Under Zhao Wen's arrangement, Li Xiaosan also hastily followed Zhao Wen's instructions to take some of the grain seized from King Fu and distribute it to the local people.
Because Song Hu also distributed military rations before, the people in Xingyang City did not have much reaction.
Zhao Wen was stationed in the county government office in Xingyang City. Because the Ming Dynasty had a tradition of officials not repairing government offices, the government offices in Xingyang City looked very dilapidated.
Zhao Wen sat in the hall of the yamen, the chair under him creaked non-stop.
The hundred households left behind by Song Hu stood beside Zhao Wen, reporting something related to Xingyang.
"My lord, there are less than 100 defenders in Xingyang. When we arrived at the city of Xingyang, the defenders in the city did not dare to resist and surrendered directly." The hundred households left behind by Song Hu said.
Zhao Wen chuckled and said: "It is a good thing to be able to take Xingyang City without bloodshed, although with our strength, it is not difficult to take Xingyang City.
You will hand over the captives in the city later. After handing over, take your men and horses, go get some food and supplies, and then chase Song Hu. "
"Obey!" The hundred households saluted Zhao Wen, and then retreated.
When the sun was setting on the western mountain, Li Xiaosan brought some soldiers to the county government office.
Li Xiaosan held a letter in his hand, and he came from Xuanzhen.
At this time, Zhao Wen was sitting in the study, perfecting the rules and regulations that had not been completed before.
Although the drawings and the manufacturing manual of the wood-burning car were produced, no one except Zhao Wen could drive this car, so Zhao Wen had to write an operation manual.
Li Xiaosan stood at the door of the study and knocked on the people in the study, "My lord, there is a letter from Xuanzhen, and it was sent by Mr. Song."
"Mr. Song? Song Yingxing?" Zhao Wen put down the brush in his hand and looked towards the door, "Come in, the door is unlocked."
Li Xiaosan pushed the door in and put the letter in his hand on the table in front of Zhao Wen, "My lord, this letter was sent by Mr. Song, saying that the light bulb has been successfully manufactured, and several factories for making light bulbs have been established." assembly line."
When Zhao Wen heard this, he became excited instantly. He hurriedly picked up the letter on the table, checked the seal, and opened it.
Zhao Wen's eyes kept scanning the letter. After a while, Zhao Wen slapped the letter in his hand on the table and stood up excitedly.
"Haha!" Zhao Wen laughed loudly, "I didn't expect it, I didn't expect it, the electric light bulb was manufactured so quickly, it was beyond my expectations. The lessons I gave Song Yingxing before were not in vain, really not in vain. "
Zhao Wen laughed excitedly.
"My lord, is this light bulb the kind of lighting device you mentioned earlier that doesn't use candles?" Li Xiaosan looked at Zhao Wen.
"That's right, it's that kind of lighting device. Now that the light bulb has been manufactured, it will be installed in every corner of Xuan Town.
In this way, factories in Xuanzhen can work at night, and tax revenue will increase accordingly.
Nowadays, for safety reasons, trains generally do not run at night, but with light bulbs, trains can run even at night.The transportation capacity of the train will be greatly increased, and the distance from Xuanzhen to Taiyuan will be reduced a lot. Zhao Wen kept explaining, the smile on his face never disappeared from the beginning to the end.
To a certain extent, the importance of light bulbs is not inferior to things like cement glass. Although they are not comparable to steam engines, they are still comparable to cement glass.
Light bulbs can liberate people from the darkness and greatly improve the efficiency and speed of labor?
And it will also reduce the occurrence of fire to some extent.
In this era dominated by wooden structures, lighting tools such as candles can easily cause fires.
With things like light bulbs, you can greatly reduce the occurrence of fires.
Zhao Wen sat down, took out a piece of rice paper, and started writing.
What Zhao Wen wrote was a letter commending Song Yingxing. Although Zhao Wen provided the blueprint and production process of the light bulb, Song Yingxing also spent a lot of effort in manufacturing it, so he should be rewarded when the award is due.
After a while, Zhao Wen finished writing the letter, put his seal on it, and sealed it.
Zhao Wen originally wanted to hand it over to Li Xiaosan now and let Li Xiaosan send someone to Xuanzhen, but now the firewood cars and other things have not been completely completed, so Zhao Wen temporarily left the letter of commendation, and waited until all the things were completed. After everything is completed, send it to Xuanzhen.
In the afternoon of the next day, Zhao Wen handed over all the finished things to Li Xiaosan, "You send someone to send all these things to Xuanzhen and hand them over to Song Yingxing. Remember, these things are very important, not even important. Next to the train, there must be no mistakes."
Li Xiaosan took the things that Zhao Wen put into a wooden box, and nodded heavily, "Don't worry, my lord, I will definitely let these things reach Xuanzhen safely, and hand them over to Mr. Song safely."
After Li Xiaosan finished speaking, he took these things and walked out.
A moment later, more than a dozen war horses galloped in the direction of Xuanzhen.
……
"Teacher, the light bulb we made before is still on. It has been on for several days, and it has been on. It is much brighter than a candle."
In the yard of a building complex next to the ironworks, a young man about 20 years old looked at Song Yingxing who was sitting in the yard and was writing something, and said excitedly.
Song Yingxing put down the brush in his hand, and said with a smile: "This is something designed by the Chief Soldier, can it be bad? Which of the things designed by the Chief Soldier is not good?"
"That's true!" The young man nodded.
"Don't hang around here, go to the laboratory and stare at the light bulb to see how long it lasts.
Now the assembly line for building light bulbs is almost completed, and the power plant is also under construction. As a teacher, I have been very busy these days. "
Song Yingxing said, then stood up, put all the things on the table into the basket on the ground, and then handed them to his students, "Send these things to the file room and seal them up. Without my order, no Anyone can open it.
The teacher is going to visit the power plant under construction now, and it is about to be completed in the past few days, and the teacher is going to inspect it.
Go ask your senior brother Li and the others to come over and accompany you as a teacher. "
The student took the basket from Song Yingxing, saluted, and then hurried out with the basket.
Song Yingxing is now the head of the Ministry of Industry and Research Institute.
Zhao Wen also specially asked someone to build a very large yard for him, so that he could study these things carefully.
Song Yingxing also lived up to Zhao Wen. After serving as a research institute, he manufactured the light bulb.
Not long after, seven or eight young people aged 27 or [-] stood in front of Song Yingxing.
"teacher!"
These people looked at Song Yingxing and bowed in salute.
Song Yingxing nodded and said, "Let's go, accompany Master to the power plant."
After Song Yingxing finished speaking, he walked outside.
His students hurriedly followed behind him.
When Song Yingxing walked out of the gate of the research institute, the soldiers patrolling outside the gate saw him, stopped hurriedly, and saluted Song Yingxing.
Song Yingxing waved his hand back and saluted, then got on a tricycle rolled out by his students from the research institute, and headed for the distance.
The research institute is said to be the most important place in Xuan Town today. Around the research institute, there are a large number of soldiers and horses with live ammunition to protect them.
These soldiers and horses were on the bright side, and some were in the dark. Except for Song Yingxing and his students, other people were forbidden to enter and exit, unless they had a special pass.
If not, you are not allowed to enter. If you force your way, no matter who it is, the defenders have the right to shoot directly.
Song Yingxing sat on a tricycle and was led by one of his students.
Around the tricycle, other students followed Song Yingxing on bicycles.
Tricycles can be used not only to pull goods, but also to transport people.
It was almost two or three kilometers away from the research institute to the power plant under construction. Song Yingxing and the others arrived at the construction site of the power plant after walking for a short time.
Today's power plant is still a huge construction site, full of busy workers.
Power plants are still a high-tech existence in this era, so when Song Yingxing asked people to build power plants, they did not use captives, but specialized craftsmen.
Zhao Wen had given Song Yingxing the blueprint of the power plant before, so there was no difficulty in building it.
Song Yingxing jumped off the tricycle and came to the gate of the construction site.
Looking at the busy construction site, he took a deep breath and showed a gratified smile on his face.
In another ten or so days, the power plant will be completely completed, and the generator can be assembled by then.
Once the power plant is complete, laying of the wiring begins.
"Adults once said that if placed outdoors, the wires that transmit electricity can be exposed and do not need to be wrapped with insulating materials.
However, the wires entering the room must be wrapped with insulating materials.Now that the palace is also under construction, the palace must be the first to use electric lights for lighting, so the newly produced insulated wires must be installed in the palace first. "
Song Yingxing looked at the construction site in front of him, his face was full of excitement.
After receiving various advice from Zhao Wen, Song Yingxing also manufactured insulated wires.
Because there is no rubber, Song Yingxing wrapped the copper wire with sackcloth soaked in tung oil.
Since there is no aluminum, the wires are just copper wires.
Because the insulation of linen is not as good as that of rubber, when producing wires, they are wrapped in thick linen.
Every time a layer of linen is wrapped, it is brushed with a large lacquer. After drying, it is wrapped with a layer of linen, and after wrapping, it is painted with a large layer of lacquer.
By analogy, the wires have been wrapped airtight.
In this way, the time to manufacture the wire will rise a lot.
But there is no way to do this. After all, there is no rubber now, so this kind of soil method can only be used.
"Teacher, it is estimated that when the commander-in-chief returns home in triumph, the palace will be completed, and our electric lights will be spread all over the streets and alleys." A student looked at Song Yingxing.
