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

How big is a large steam engine, if you take a four-horse carriage, the length of this equipment is at least the length of ten carriages.

The Workshop's research team has been working on this device since the steam engine began to be used as a powerhouse.

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

"Test it now."

The steam engine was put into operation, and 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 pointer on the large pressure gauge quickly reached the standard.

The huge machine began to rotate, and there was a huge round iron column in the middle, and then the large boring head on the machine was seen rotating in the middle of the iron pillar, and the iron filings slowly withdrew with the rotary knife.

Li De looked at the thigh-thick barrel being made, and was very excited, if it succeeded, Youzhou would not be afraid of any force.

The secret project could be realized so quickly, and he had to admire the wisdom of the ancients.

It takes time to manufacture, and even with the drive of a steam engine, it is not so easy to make a qualified product.

The cannon he designed was a simple firing rope that could not make shells, so he had to use this old-fashioned design.

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

Li De knew that they were just here to see the excitement today, and of course he didn't forget to give some benefits to the craftsmen.

As for whether the finished product can be really successful, we still have to wait for the final assembly to know.

Half a month later, there were no people in the suburbs of Youzhou, and the old cannons that had been set aside for a long time were the latest ones.

There was no one except Li De and the Lu family brothers and a few craftsmen.

Whether it really works or not depends on the results to know.

"Let's start experimenting."

At the beginning of the test, the craftsmen opened the wooden box containing the ball shells, and the side of the cannon was trimmed to a flat pile, and a mound of earth was enclosed around it.

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

The craftsmen began to test, and they were all very much looking forward to it.

For safety, two-metre torches are used for ignition.

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

Boom, there was a loud bang, there was no explosion, and then I saw the gravel flying at least five thousand meters in the distance.

When the smoke cleared, the craftsmen began to experiment again and again, and the continuous firing caused the temperature of the cannon to continue to increase.

Two wooden boxes of ammunition, with thirty shells of pellets, all tested at the end of the artillery temperature in the cold winter conditions were much better.

The craftsmen expected that the cannon would not be able to be used so intensively and continuously at normal temperatures, and would need to be cooled down at least every five intervals.

The way is very straightforward, which is to water directly.

"It's already good, how long does it take to make a cannon with this process?"

"Five days is enough."

"Very good, produce a hundred first."

As soon as Li De opened his mouth, he spent a huge amount of money, and he didn't hesitate at all to spend 100,000 yuan like this.

The workshop will share at least 20% of these expenses, and the workers will be paid wages to start the work, and the price is still acceptable after counting the cost of materials.

Li De visually measured that if the artillery of the current caliber went to attack the city, it could smash the gate of the city wall with one shot, and the investment of 100,000 yuan was very cost-effective.

What are you afraid of with such a sharp weapon?

Many of the people of Youzhou City stayed at home in winter, and when they heard the continuous sounds, they all thought that it was the manifestation of the mountain god, and the people who did good things came out to explore.

When they met the vanguards, they were all stopped, and there was no explanation that they had heard that something new was being tested in the workshop, and the people all turned back home, but their curiosity did not disappear.

No matter how strong their curiosity is, Li De will not let them know, how can this kind of weapon of war be easily revealed.

Get more inventory first, it will work when it is critical.

The winter in Youzhou is not cold at all, and the workers in the workshop are still working every day, and the heating stove in the workshop does not affect their work.

After Li De left from the Lu brothers, he went to the paper workshop, and the blacksmith workshop was full of the smell of coal, and the smell was even more strange when he arrived at the paper workshop.

The taste was too strong, and Li De didn't go in at all.

The steward who managed the workshop came out with new paper, some thin and thick, some white and some yellow.

Different paper uses don't work.

Li De looked at the results, inquired about the cost and production capacity, and then went to the woodworking workshop after learning about it.

Paper is a very important product, and people all over the world need to have a new type of papermaking technology to greatly reduce the cost.

The main thing is to be able to solve the problem of personal hygiene.

The paper produced by the paper workshop has always been a sought-after commodity in Youzhou, and the new paper workshop has been expanded, otherwise it really can't meet the demand.

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

Although Li De does not often visit the paper workshop, in fact, the production of the workshop 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 carpentry workshop and asked the craftsmen about the progress of movable type printing and engraving.

His plan was to generate more books, and a few sets of movable type printing were not enough, and he was not afraid to spend money, and the carpentry workshop was also profitable after receiving orders.

After the expansion of the school, the number of books needed increased, and the increase in the number of movable type printing could meet the needs of different people for books.

Li De will not print those things that make people shake their heads, all of them are elementary mathematics, physics and chemistry textbooks, and some story books.

In the story books, in addition to some books that some people spend money to publish, the most are some books that are used, such as idioms, allusions, and encyclopedic knowledge.

There are also a lot of books on knowledge and specialization, and there is a lot of demand for textbooks for medical schools.

Li De had nothing to do and checked all these industries, and he was pleased that all the industries were very good.

When he returned to the Governor's Mansion, Zhang Chuchen came out to answer him, and when they met, he asked, "Husband, what happened in the suburbs today." ”

Zhang Chuchen is the person in charge of Red Peony, and she was the first to know many things, and he didn't tell the details that his affairs today were very secretive.

"There is something new in the workshop, and the test is carried out today, which is a weapon of war, and do not make a noise."

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

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

Li De will not ask about these little things.

Li De is sleeping in peace now, and with the help of artillery, the sense of crisis is also slightly eased.

The whole winter in Youzhou is not peaceful, because every three or five times you will hear a loud noise from the mountains, although the city guard has stated that it is a test of new products, but the people's thoughts are uncontrollable.
