Traveling through history leaving a name

Chapter 15 Machinery
At this time, in Erdaogou Village, Zhang Qingfeng was receiving Wang Wei, a student who had graduated from him and was an official outside the mountain.

"Teacher, I want to take some juniors out to help me." During the meal, Wang Wei respectfully said to Zhang Qingfeng.

"No."

Hearing Wang Wei's words, Zhang Qingfeng directly shook his head and refused.

"Why?" Wang Wei paused while eating.

"Because you have already graduated and your juniors were taken away by Li Bai, and the rest are unfinished." Zhang Qingfeng explained.

Li Bai has poached 31 people from him, plus more than a dozen people who were arrested by Li Bai and Du Fu, it can be said that the older children he taught in the first batch were basically taken away.

Even Li Bai, a fast learner who was only 13 years old this year, was taken away when Yang Shen came back last time.

Before leaving, Yang Shen also said: Although the younger brother is young, he has already learned something, and he just took it outside for exercise.

"Ah? Were all taken away by that guy Li Bai?" Wang Wei was stunned when he heard Zhang Qingfeng's words.

Wang Wei's place belongs to Wu'an County, Guangping County. Due to the distance, he waited for several months before looking for an opportunity to come back.

He has been in power in Wu'an County for a few months. Because he is too young, he is looked down upon by others, which makes it difficult for him to perform locally.

Compared with the county magistrates in other counties, he is in a good or bad situation. He doesn't want to be so mediocre, he wants to make a difference, so he has the idea of ​​coming back to find someone.

It's just that he didn't expect that when he came back, he came back, but he was packed and poached by Li Bai, which made him feel like crying.

"Teacher, just give me a few juniors. It's really difficult for me to be outside alone." Wang Wei began to grieve, and he made up his mind that this time he must find some people to go back to be helpers.

"No, you can't take away those who haven't graduated. They still have a lot to learn, so you can't be too selfish." Zhang Qingfeng didn't look good either.

"Then I can find a few senior sisters and sisters, shouldn't they graduate?" Wang Wei rolled his eyes and thought of a way.

Although Li Bai took away his juniors, there are still seniors and sisters.

They were also well-educated, and they had studied with Zhang Qingfeng for a year longer than the young men. He believed that their ability would not be inferior to them.

Hearing Wang Wei's words, Zhang Qingfeng thought for a while and nodded: "Yes, but you can only take five people with you, and you need their own consent."

The reason why only five people were released was mainly because the remaining ones, Zhang Qingfeng, wanted them to stay as teachers for the students.

Two days later, Wang Wei finally left satisfied.

As soon as Wang Wei left, Li Kui came.

Li Kui also came to find someone. When he came, he found hundreds of peasants and brought a lot of supplies, fine porcelain, soybean oil, ironware, and school supplies, etc. He even drove a few cows back. It was a hit.

Afterwards, he lobbied in the village, hoping to find some young and strong people to go out to do business. He said it was business, but in fact the main purpose was to protect their property.

Many people were moved when they heard that the porcelain workshops and oil pressing workshops run by Li Kui and the others could earn 60 million yuan a month.

They farm at home, even if they sell all the grain they grow in a year, it will only cost thousands of dollars. They still need to eat, buy oil, salt, sauce and vinegar, and everything will be spent. Two thousand dollars is an incredibly rich life.

Li Kui recruited people and paid a high salary, three thousand yuan a month, tens of thousands a year, which was much more cost-effective than farming.

Of course, it is impossible for Zhang Qingfeng to let Li Kui take away all the young and strong in the village, otherwise there will be no one to cultivate the fields next year.

So he asked Li Kui to recruit more people in other villages and towns in Shili Baxiang.

Especially for those who have children studying in Taihang Academy, they can feel at ease when they are recruited back.

In Erdaogou Village, a lot of young adults have left in the past two years, which forced Zhang Qingfeng to consider inventing some more efficient agricultural machinery.

Such as planters, harvesters, and other machinery.

Although the sowing efficiency of the current columbine carts is considered good, the efficiency of the columbine carts is still too low in the case of insufficient manpower.

Zhang Qingfeng is aware of machines that are more efficient than columbine carts, such as plows with many plows, and animal-powered seed drills in the [-]th century.

These machines can speed up farming efficiency, and for Zhang Qingfeng, a college student who graduated from a 21st century science and engineering university, the structure of these machines is very simple.

In addition, Li Kui sent some good steel and iron when he came back this time, so he planned to take the time to make these machines.

Fortunately, the school now has graduated Li Shishi and the others in class, and with the teaching materials, the school can operate normally with him or without him, so Zhang Qingfeng has time to busy himself with his own affairs.

For these steels, Zhang Qingfeng's first thought was to manufacture some hydraulic cutting machines, hydraulic grinding machines, milling machines, boring machines and the like, with simple structures and primitive machinery.

These machines do not require precision, as long as they are simple in structure and capable of cutting, grinding, and processing rough embryos.

For more precise parts, he can slowly grind them with a file and a whetstone. Although he is not a professional fitter, general parts processing is not difficult for him.

The production of files is actually very simple. After heating and softening with a steel rod, use a tool to mark the texture, and then quench it to get an ideal file.

There is no problem with processing ordinary mild steel with this file.

If the processed parts are too hard, you can also anneal the processed parts to lower the hardness of the workpiece, and then normalize or quench after processing.

Of course, it is also possible to use soft wrought iron to make the file. After the wrought iron bar is textured, it can be carburized and quenched directly.

Carburizing can form a layer of low-carbon steel on the surface of wrought iron bars. After quenching, the hardness is harder than ordinary low-carbon steel, and can be used to process wrought iron components.

Of course, files made of steel can also be carburized, which allows the surface to form a layer of high-carbon steel, which makes the file harder.

Here Zhang Qingfeng is trying to make machine tools in the Taihang Mountains, but in Yuyang County, the battle between Wuhuan and Xian Yufu has reached an anxious turning point.

Fortunately, there is a city wall guarding here, and the Wuhuan people still have nothing to do with Cao Jun's side for a while.

However, the Wuhuan people had the upper hand in force, and it was very difficult for General Xian Yufu's troops.

What's more difficult is that the peasant uprising that broke out in Zhuojun has not been suppressed, and most of Cao Cao's troops have been invested there, so the Wuhuan people can only be supported by Xianyufu for the time being.

"General, our ordnance has been consumed too much. We must find a way to get Youzhou to replenish our ordnance, otherwise this battle will be impossible."

Xianyu Fushuai account, a logistics officer, Joseon Yufu, said.
