After more than a month of all-out transformation, the transformation of 30 second-generation steam engines was finally completed.

Zhu Shun can also rest assured that he can study the industrial machine tool, which requires a lot of silver investment.

Before researching industrial machine tools, Zhu Shun decided to study the mechanical sawing machine first, and realize the mass production of Zhu's spinning machine and shuttle loom.

The craftsmen of the Beiping Machinery Bureau built these two new machines that were most in demand, all of which were hand-built and processed little by little with saws.

This has also caused the production efficiency of Zhu's spinning machine and flying shuttle loom to not go up.

Cutting wood by hand, it's too slow.

Tens of meters of wood can be cut out in a day, and the speed is already very fast.

The mechanical sawing machine can achieve 30~60m/s.

Thirty to sixty meters are cut in one second.

Tens of meters a day and 30 meters a second, the difference between cloud and mud.

Before the mass production of coal and steel, steam factories that consumed a lot of steel were very expensive.

A steam workshop and a steam engine cost fifteen hundred taels of silver, not counting some other facilities.

There are many generals gathered under the banner of the Textile Association, but most of them are poor families with patches.

They all wanted to make the transition between the water-powered Zhu's spinning machine and the flying shuttle loom first, and then build a steam factory and buy a semi-metal spinning machine with 300 spindles.

This has caused a large gap between Zhu's spinning machine and flying shuttle loom, and the speed of a group of craftsmen in Beiping Machinery Bureau five units a month cannot meet the needs of the seed brothers.

Zhu Shun heard from the third uncle that the queue was almost ten years later.

It is also necessary to spare some manpower to create various mechanical parts and replace damaged parts.

This queue has been more than 20 years.

The steam engine in the middle of the No. 0 experimental courtyard was moved to a place near the wall, and the middle was replaced with a craftsman's table.

Zhu Shun sat on the official hat chair next to him, constantly writing and scratching, thinking about the structure of the mechanical sawing machine.

When it was almost noon, there was a generous young man at the door, wearing a Songjiang purple cloth winter jacket, and walked into the No. 0 experimental courtyard.

The man in the iron tower standing at the door was able to let the young man in, which showed that the relationship between the young man and Zhu Shun was not simple.

The boy walked into the No. 0 experimental courtyard and saluted respectfully: "Teacher, the improved version of the rocket has been successful. ”

Zhu Shun heard that the improved version of the rocket was successful, and he didn't have the heart to continue writing and sketching here, so he put down the charcoal in his hand: "Let's go, go and see." ”

Zhao Doumi's experimental courtyard is the No. 4 experimental courtyard.

The experimental courtyard occupies a large area, much larger than the No. 1 experimental courtyard with rice fields in the courtyard.

It occupies a large area, but there are very few buildings inside.

There are only a few viharas.

The rest of the land is all empty land.

The land is full of potholes and has many large potholes.

Zhu Shun walked into the No. 4 experimental courtyard, where Wang Zheng and several disciples were there.

In the open land, there is a rocket launcher, and the rockets on the rocket launchers are completely different.

At the beginning of the creation of the rocket, the shell was made of several layers of cardpaper.

The shell of this new rocket is a layer of shiny black iron.

There have also been a lot of changes in styling.

The head of the rocket is still a bullet, and a cylindrical iron sheet is added behind the warhead.

The appearance is already very similar to modern rockets.

Zhu Shun walked into the experimental courtyard, and the clever Song Shiyi walked over with a report and hugged his teacher's arm.

Zhu Shun rubbed Song Shiyi's head, took the report, and read it carefully.

Dongfeng Type 1 (modified)

Mass: 31 pounds.

Arrow length: 1.06 m.

Diameter: 0.1 m.

Balance bar: 4.6 meters.

Range: Not tested.

Zhu Shun put down the report, and under the expectant gaze of the disciples, walked to the rocket launcher and picked up the torch.

"Whew!"

After the rocket lead burned, a large number of sparks erupted from the tail, propelling the rocket to fly out.

In an arc, it fell to the ground.

"Boom!"

The moment the rocket hit the ground, it exploded into a dazzling fire, blowing up countless pieces of dirt.

A larger pit was flipped out, and the ground shook slightly.

Several disciples who were impatient, and without waiting for Zhu Shun to speak, a group of people ran over to measure the distance.

After a cup of tea, Song Shiyi ran over happily, shook his arm and said, "Teacher, the range has reached one mile." ”

Zhu Shun was even more satisfied when he heard the range of the new rocket, the length of five football fields is definitely a major breakthrough.

When the disciples all came over, Zhu Shun and the disciples all looked at Wang Zheng.

Wang Zheng remembered his gambling contract with Zhu Shun, his old face flushed, and he coughed lightly: "Ahem, okay, wait for the old man to get two pots of wine, and invite you to drink in the dining house." ”

The eldest disciple Song Shihui held the cigarette pouch silently and smoked one bite at a time.

The third disciple Jiao Miao looked at the deep pit in the distance with a fiery face, and he didn't care much about whether he drank or not.

The fourth disciple Zhao Doumi stood with a smile and looked at the old man Wang who was slamming the door.

Only the second disciple Song Shiyi was not happy, and pulled the old man Wang's white beard fiercely: "You are too picky." ”

"How can I say that I have a monthly amount of one hundred taels of silver a month, and invite us to eat in the free dining house, and you can figure it out."

Wang Zheng didn't seem to hear Song Shiyi's dissatisfaction, said that the old man went to drink, and ran away with a cigarette.

Zhu Shun knew that no one in his group of disciples was in the mood to drink, and there was not enough time for research, so where would he have time to drink: "Mr. Wang is famous for slamming the door, so don't make fun of him." ”

"Let's go back and continue our research."

When the other disciples were gone, Zhu Shun took Zhao Doumi to the fine house, sat on the official hat chair and said, "Doumi, I'm going back this year." ”

"I'll leave later, and I will go to the emperor for the division to recommend you as the head of Wang Gong's artillery factory, which can be regarded as an official entry."

"In addition, this Dongfeng Type 1 bought the patent right for the teacher at a price of 10,000 taels of silver, do you think it's good?"

Zhao Doumi propped his hands flat and bowed solemnly: "Thank you for the grace of the teacher's reconstruction." ”

"As for this Dongfeng Type 1, it should be regarded as a bundle given by the disciple to the teacher."

Zhu Shun rubbed Zhao Doumi's head, let him sit beside him, and said with a gentle smile: "I'm about to go back to my hometown, it costs money to buy gifts for relatives and friends at home, and it costs money to buy a sedan chair to support the scene." ”

"When I see the younger generation for the New Year, I still have to spend money."

"You have become a Beijing official in the capital, and in the eyes of the old family, you are a great scenery, don't you donate money to rebuild the ancestral hall and renovate the ancestral tomb."

"Everything costs money, take your mother over next year, and this money is just right to buy a house in the capital."

Zhu Shun finished speaking earnestly and left here.

Zhao Doumi still held his hands flat, bowed solemnly, and couldn't get up for a long time.

When he got up, he lifted his face.

His face was full of tears.
