The temperature in the Youzhou workshop is very high, and the operation test of a large steam engine is being carried out in the workshop.

How big is a large steam engine? If you look at the carriage drawn by four horses, the length of this equipment is at least ten carriages.

The research team at the workshop has started to build this equipment since the steam engine started as power.

Senior craftsmen such as Li De and the Lu brothers were all watching.

“Test it now.”

The steam engine began to operate. In order to provide the kinetic energy supply of this huge equipment, the steam engine was very large, and several people began to add coal to the boiler.

The pointers on the large pressure gauge quickly hit the standard.

The huge machine began to rotate, and there was a huge round iron column in the middle on it. Then the large boring head on the equipment rotated in the middle of the iron column, and the iron chips slowly exited with the rotating knife.

Li De was very excited to see the gun barrel that was thick with thighs being made. If he succeeded, Youzhou would not be afraid of any force.

The secret project was able to be implemented so quickly that he had to admire the wisdom of the ancients.

Manufacturing takes time, and it is not so easy to make qualified products even with the help of steam engines.

The cannon he designed was a very simple fire rope and could not create shells, so he could only use this old design plan.

"Grandmaster, the equipment is operating normally, and it will take some time to make the product."

Li De knew that they were just watching the fun today, and of course he did not forget to give some benefits to the craftsmen.

As for whether the finished product can be really successful, it will only be known after the final assembly.

Half a month later, there were no people in the suburbs of Youzhou, and the latest old-style cannons were produced in the martial arts field that had been set aside for a long time.

There was no one else except Li De, the Lu brothers and several craftsmen.

Whether it really works depends on the results.

"Start the experiment."

At the beginning of the test, the craftsmen opened the wooden boxes containing meatballs and shells. The piles next to the cannon were trimmed very flat, and a pile of soil was also surrounded.

It looks very "style", but it is actually useless, but it does not affect Li De's request.

The craftsmen started testing, and they were all looking forward to it.

For safety, the ignition is made of two-meter-long torches.

Li De and the Lu brothers are far away, so it is risky to conduct tests.

There was a loud bang, no explosion, and then the gravel was flying around at least five thousand meters away.

As the smoke of gunpowder dissipated, the craftsmen began to continue to conduct experiments over and over again, and the continuous firing caused the temperature of the artillery to continue to increase.

The two wooden boxes of ammunition, with thirty meatballs, all of which were tested and the temperature of the artillery was much better in the cold winter.

According to the craftsmen's expectations, if the gun is under normal temperature, it cannot be used continuously so intensively, and it needs to be cooled down at least every five intervals.

The method is very straightforward to water directly.

"It's already very good. How long does it take to build a cannon with this process?"

"Five days are enough."

"Very good, produce one hundred doors first."

Li De spent a huge amount of money as soon as he spoke, and he had no hesitation at all if he spent 100,000 yuan like this.

Among these expenses, the workshop will be divided into at least 20%. The work will be paid to the craftsmen. The price is still acceptable if it is included in the material fees, etc.

Li De visually estimated that if the current caliber artillery cannon will be able to smash the gate of the city wall with one shot, and an investment of 100,000 yuan is very cost-effective.

What are you afraid of with such a powerful weapon?

Many people in Youzhou City stay at home in winter. When they heard continuous sounds, they all thought it was the mountain god appearing, and people who were good at it came out to explore it.

When they met the vanguard soldiers, they were all stopped. There was no need to explain that there was something new in the workshop to be tested, and the people all returned home, but their curiosity did not disappear.

No matter how strong their curiosity is, Li De will not let them know. How can such a powerful weapon of war be easily shown to others?

Get more inventory first and it will have an effect when it is critical.

The winter in Youzhou is not deserted at all, and the workers in the workshop are still working every day. The workshop has heating stoves that do not affect their workmanship.

After Li De left the Lu brothers, he went to the papermaking workshop. The blacksmith workshop was filled with the smell of coal, and the smell was even more bizarre when he arrived at the papermaking workshop.

The taste was too heavy and Li De didn't even enter.

The manager of the management workshop took new papers to display them, some thin and some thick, some white and some yellow.

Different papers have different uses.

Li De looked at the results and asked about the cost and production capacity. After learning about it, he went to the wooden workshop.

Paper is a very important product, and scholars all over the world need to have new papermaking techniques to greatly reduce costs.

More importantly, it can solve personal hygiene problems.

The paper produced by the papermaking workshop has always been a short supply of goods in Youzhou. The new papermaking workshop has been expanded, otherwise it will not be able to meet the demand.

In addition to daily paper, oil paper is also produced, which is used for some special purposes.

Although Li De did not often ask about paper workshops, the production of workshops has always been closely related to the lives of the people.

In particular, the paper used for personal hygiene is a major feature of Youzhou.

Li De came to the carpenter workshop and asked the craftsmen about the progress of printing and engraving of movable type.

His plan is to trigger more books. It is not enough to print with a few sets of movable type. He is not afraid of spending money. The carpenter workshop can be considered a commercial profit after receiving orders.

The increase in books required after the expansion of the school and the increase in the number of movable type printing can meet the needs of different people for books.

Li De would not print those things that make people shake their heads, they were all elementary mathematics, physics and chemistry textbooks, and some story books.

Among the storytelling books, except for some people who spend money to publish the most are books used, such as idioms and allusions, encyclopedia knowledge and common sense.

There are also many books on knowledge majors, and medical school textbooks are needed in a large number.

Li De had nothing to do with all these industries, and what made him feel relieved was that all industries were very good.

When he returned to the Governor's Office, Zhang Chuchen came out to respond to him and asked when he met: "Husband, what happened in the suburbs today."

Zhang Chuchen is the person in charge of Hong Mudan. She knew a lot of things first. He didn't know the details and explained that his affairs today were very confidential.

"There is something new in the workshop. Today, it is a weapon of war. Don't make a name for yourself."

"Okay, I'll have someone arrange it later."

As the official, they still need to give an explanation.

Li De would not ask about these trivial matters.

Li De is now peaceful when he sleeps. With the help of artillery, the sense of crisis is also slightly alleviated.

Youzhou was uneasy all winter because you could hear loud noises from the mountains every now and then. Although the city guards had already shown that they were conducting new products, the people could not control their ideas.
