The mining of iron ore is not a matter of overnight. There are several iron ore secretly occupied by Youzhou now, all of which are camouflaged and mined in the name of commercial use.

The output is considerable and provides a large number of jobs for the transport fleet. There are many people in Youzhou, most of whom are once displaced.

The treatment for mining iron ore is very generous, so it is done very well in terms of confidentiality. It is very luxurious to melt a large amount of iron ore into a boiler now.

The people in the R&D team have mastered the drawings provided by Li De, and they are all looking forward to the steam engine being able to achieve it.

Li De also often goes to the workshop to inspect and guide, and uses some knowledge to help the craftsmen give advice.

The boiler was built very quickly. After a large amount of iron ore was invested, the first steam boiler was built as big as half a room.

The iron used is very thick and fixed firmware, which gives people a very large and bulky appearance.

Today, Li De is here to wait for trial. All the craftsmen in the R&D team in the workshop are there, and Li De doesn't call too many people.

It is better to have fewer people in the first experiment.

The key is that there is no pressure gauge, and you can only pour pressure through the exhaust valve. This kind of thing needs to be controlled by people.

According to the operating procedures, the experimenter only started after re-confirmation. In order to prevent excessive pressure, the coal in the boiler is limited.

After the boiler is burning, it waits for the steam in the water tank to make a sound in the exhaust hole, and then closes the exhaust valve and directly lets the steam drive the flywheel through the air plug.

Li De watched from a distance that he did not dare to get close to something like a boiler without a pressure gauge. Even if there is a pressure gauge, he would not take risks with current iron smelting technology.

"Grandmaster, watch the flywheel rotate." Lu Mingxing said happily.

Before performing this experiment, Li De said it very clearly how much value the steam engine can bring to the workshop. The Lu brothers had heard of all the plans.

They are both carpenters and are very persistent in technology, especially I heard that steam and mechanical techniques have some connections. They are very interested in this project.

The steam furnace has driven the flywheel to rotate, and they all saw it. The steady speed drives the grinder that has been prepared for a long time to rotate slowly, and the speed is very symmetrical.

Lu Mingyue was not satisfied with the current Chengdu, so she asked the craftsmen to continue to add some coal blocks to the boiler. As the steam pressure was high, the speed of the flywheel began to increase.

Li De just watched it, the millstone pushed can reach two or three hundred kilograms. Although the speed is not fast, the strength is still enough.

It is easy to drive slow machine tools according to this situation.

He could already think that using steam engines for drilling holes, slow drilling is similar to platform drilling, and the speed is enough to ensure a basic continuous speed.

If the Youzhou Workshop succeeds, it can be used to process iron pipes, and there should be no problem in manufacturing a few Hongwu cannons at that time.

"Shishe!"

"Open the deflation valve quickly!" Li De heard the steam warning sound, and the rapid sound made people feel uneasy.

Li De shouted immediately, at this time, the personnel who were reminded to respond in time, and the workers who were just in a hurry subconsciously pulled the valve.

The air discharge port opened, and the flywheel on the steam engine began to slow down, but the coal temperature in the boiler increased, and water was added again at this time.

After some processing, the flywheel slowly stopped.

"Governor, are you okay?"

"It's okay, check some steam engines. It seems that it's really not possible without a pressure gauge. Stop the experiment first and call all the craftsmen with the best skills in the craftsmen over." Li De ordered.

After a while, the highest level of craftsmen were called to the office, and Li De drew a design drawing of a pressure gauge on the drawings.

The technology required is not too high, but the craftsmen who are required to strive for excellence and complete the various accessories inside.

Especially for pipe sealing, there is no turntable wrench now, but can only be made with a saw blade bit by bit, and it is not possible to check it out.

After seeing the drawings, the craftsmen immediately divided the work and cooperated. They did not create something reasonably, but created the final and most matched parts in batches for fine grinding.

This is how the workshop makes parts that require precision, and each time it can be created, and the rest can be used as backup after reprocessing.

"Lu Mingxing, let's put the steam engine matters first, and when will the pressure gauge be completed and when will the test be conducted."

Li De directly stopped the project with one sentence. This kind of thing is very common, mainly for safety considerations.

With today's experiments, the craftsmen in the R&D team have learned about steam engines, and some of them have begun to study the application of machine tools.

Li De also gave some suggestions, yes, you can also study the matter of manufacturing Hongwu cannons after having a steam engine.

The Lu brothers' faces were calm. They were very happy when they heard the weapons that created great power, but they didn't think so when they calculated the iron.

Li De had no choice. This is the current situation. What they made were the most basic artillery.

Finally, the final plan was to start manufacturing cannons with muskets, and it was unrealistic to get it done in one step.

Li De has been working in the workshop recently. He spent almost all the money he had just made after working on a project. The finances of Pioneer Army have repeatedly entered a loss-making state.

Li Shimin continued to work hard, encouraging merchants to do business and check the store taxes to surpass the financial resources of the pioneer soldiers. Now, there is no result. The projects invested by Li De directly spent all the profits.

People in the city guard's mansion talk about this when they are fine.

Li De did not react much after hearing the news, but Princess Yu asked the Youzhou financial department to come out independently and be directly under the supervision of the Grand Commander.

Li De didn't need to preside over these things. After Princess Yu proposed it, she completed the financial matters through Li Yang, the head of the Finance Department.

In fact, the Finance Department was originally responsible to Li De, but during this period when he was away, Li De's younger brother was in charge and Pei Qingxuan was in charge of the situation.

In the case of remarks and financial management, the model of being in charge of finance should continue, but if the Finance Department is directly allowed to take charge of Li De himself, there will be no rumors.

The system of Youzhou is very new, but it does not mean that the new system is necessarily suitable for the development of Youzhou. Li De is also trying.

All aspects need to be corrected and improved according to actual conditions.

The financial affairs of the City Shoufu and Pioneer Army will now be considered by the officials. Since this happens, the problem needs to be solved as soon as possible.

So Li De had to put down his work in the workshop first and began to manage the Youzhou account. He had decided to implement the appropriation system.

From the city guards, the vanguards need to allocate funds, as much as the vanguards need to allocate funds, as small as the various departments need to plan for the amount of funds allocated.

With the help of Princess Yu and Li Yan, the whole thing is very fast.
