After seeing off Wei Wuya, Jin Feng, led by Jin Peng, walked around the Black Wind Ridge.

Today's Heifeng Ridge is no longer deserted, because Jin Feng has built a transfer station here. More and more merchants come to Heishui Ridge to rest or simply sleep in the sheds outside the transfer station.

Tang Xiaobei thought this was a business opportunity, so he decided to build an inn here. It is expected to be completed in another half month.

The transfer station has also grown from a few tents to five large tile-roofed houses, filled with various materials such as twine, grain, iron ore and so on.

The coal was placed in the cave on the mountain by Jinpeng. Every time the coal was transferred, the ore mined by Jinpeng and the others would be transferred together.

The small cave has been dug for so long that its volume has expanded by more than half.

Overall, Jin Feng was very satisfied with the changes in Black Wind Ridge. After encouraging Jin Peng for a while, he returned to Xihewan from the suspension bridge and plunged into the laboratory.

As Xihewan develops faster and faster, Jinfeng needs to manufacture more and more things.

Now that tungsten is available, various drill bits and cutter bits can be made.

With the drill bit, you can make various basic pedal machine tools, such as lathes, milling machines, planers, drill presses, grinders, etc.

These machine tools are the basis for precision machining. With machine tools, more precise tools can be processed, and then these tools can be used to create more stable machine tools, thus entering a virtuous cycle.

In fact, lathes appeared during the Qin Dynasty in the previous life, but they did not find the right path and developed very slowly. Later, the West first discovered this virtuous cycle, which triggered the industrial revolution. Various machine tools appeared one after another and produced steam engines.

The emergence of the steam engine provided machine tools with more stable and powerful capabilities, which was equivalent to giving the industry a strong heart, and finally achieved the take-off of the industry.

Jin Feng had a complete history of the development of machine tools and manufacturing methods in his mind. As long as he was given time, he was fully confident in creating internal combustion engine trains and armored warships.

But starting from scratch would be a huge workload, and Jin Feng himself couldn't say how much resources and time it would take.

Fortunately, he has Tang Xiaobei, a money-making expert, who can give him continuous blood transfusions, so he rarely worries about money.

Mancang also basically graduated and learned how to read drawings. As long as Jin Feng gave him the drawings, he could create many things with a group of female apprentices, which greatly reduced Jin Feng's workload.

In the next few days, Jin Feng lived and ate in the laboratory and iron smelting workshop. With Mancang and a group of his female apprentices, they worked hard for several days and nights, and Dakang's first lathe was finally completed.

Although it was still very primitive, Jin Feng was very happy.

With this lathe, we have a foundation for sustainable development.

"Everyone has worked hard these days. The warehouse is full, and everyone will be rewarded with five taels of silver!"

In the past few days, Mancang and his female apprentices have been staying in the iron smelting workshop for food and accommodation. A group of older girls have made themselves dirty, and many of them have rust and oil stains on their hair.

"Thank you, sir! Thank you, sir!"

All the female disciples cheered.

Many of them were sold with their families, and they were lucky enough to be bought by Jin Feng. However, there were also family members who suffered in the dental shop, or were sold to others by the dental shop.

With money, they can find ways to redeem their families.

As for them, there is no such idea at all.

Because they are very clear, there are too many things that Mancang taught them, and it is impossible to allow them to redeem themselves and take away what they have learned.

And they are very satisfied with their current life.

Except for the village, no one can restrict them in the village.

There are full meals every day, as well as wages, and no one dares to bully them.

I don’t know how many times better than the previous days.

Even if Mancang drives them away, it is estimated that no one wants to leave.

"Sir, the lathe is so easy to use. With this thing, at most five days, I can make a weaving machine!"

Hangcang experimented several times, and I couldn't help it.

"In the future, there will be more lattles, and we can work for the assembly line. By then, there will be no need for five days, and several weaving machines will be created in one day!" Jin Feng said with a smile.

"What is a assembly line?" Mancang asked curiously.

"Each machine specializes in one or two parts, and then send these parts to the house next door, and it is assembled by a special person into a weaving machine.

"Jin Feng explained.

"This method is good!" As soon as Mancang heard his eyes, it turned on: "Everyone only makes a part, so even if this person betrayed, he will only make one or two parts, and he can't make the entire fabric machine!"

"Yes," Jin Feng nodded: "And everyone only makes one or two parts, it will become more and more proficient, and the things they make will become better and better.

"

"Right!" Mancang nodded again and again.

Jin Feng taught the basic usage of some lathes in Mancang. It was almost dark before going home.

"Ouch, how do you make it like this?"

Guan Xiaorou looked at Jin Feng's appearance, and the distressed tears were almost out: "Runniang, go to the bathroom to burn some hot water and take a bath!"

The machinery was a dirty work. Jin Feng did not take a bath to change clothes for a few days in a row. He was dirty than those female apprentices in Mancang. He was also scratched by a tool. Guan Xiaorou saw it at the first glance.

beggar.

Run Niang explored her head from the kitchen, and smiled when she saw Jin Feng: "Mrs. Xiaobei just made hot water, it was useless yet.

"

"Regardless of her!"

Guan Xiaorou pulled Jin Feng into the bathroom.

When the two came out of the bathroom, Qing Mulan, Tang Xiaobei and others had sat on the dining table.

"Well, Sister Xiaorou, isn't Xianggong going to take a bath? Why is your hair wet?"

Tang Xiaobei blinked his eyes and asked deliberately.

"Eat your meal!"

Guan Xiaorou glanced at Tang Xiaobei, and he twisted secretly with a red face.

Tang Xiaobei was not afraid at all, and made a look at the side and gave Qing Mulan a look.

Usually Qing Mu Lan also likes to tease Jin Feng and Guan Xiaorou, but today he has nothing but indifferent to Tang Xiaobei, as if he didn't see it. His face was full of sadness.

"Mu Lan, what's wrong, do you have a heart?"

Jin Feng also noticed Qing Mulan's wrong.

"Brother Qin Shi of the county came today, saying that the court's tax official document passed over, and it should be announced the day after tomorrow.

"

Qing Mulan sighed: "The tax payment plus 10 % is no longer changed!"

"The group of masters in the court really want to force the people!"

Jin Feng also lost his mind, put the bowl on the table: "Are they not afraid of the people rebel?"

"rebel?!"

In the feudal era, rebellion was a very scary and heavy topic. Everyone in the room was scared by Jin Feng's words.

"Sir, don't you?"
