Become a feudal king from today

"Your Highness, the current method of producing sulfuric acid is to use calcined pyrite and a lead chamber."

Qu Sheng pointed to a boiler.

The craftsman is throwing yellow iron ore inside. The boiler is connected to a ceramic pipe, which is in turn connected to a red brick cube.

Another tube extends from the cube, leading to a clay pot.

Zhao Xu looked up and down and nodded slightly.

Pyrite is iron disulfide, a very common iron ore.

It does not contain much iron, but contains a lot of sulfur, so it is not suitable for iron making, but it is suitable for extracting sulfur.

This low-quality iron ore is especially abundant in Dasong.

Otherwise, today, we would not buy high-quality iron ore from Australia in large quantities, so that we would be controlled by others.

During the process of calcining pyrite, sulfur dioxide is produced. After passing through the catalytic lead chamber, it is converted into sulfur trioxide and finally enters the water to become sulfuric acid.

This is the sulfuric acid industry created by Qu Sheng.

In fact, in ancient times, the ancients were able to obtain concentrated sulfuric acid by distilling bile vitriol and green vitriol.

But Yanzhou is rich in iron ore, so it is obvious that the cost of calcining pyrite to make sulfuric acid is low.

Moreover, the calcined iron ore can be used to make iron and be used repeatedly.

After visiting the process of making sulfuric acid, Zhao Xu went to the workshop where nitric acid is made.

In fact, sulfuric acid is the basis of three acids. After obtaining sulfuric acid, it is simple to prepare the remaining two.

Nitric acid can be obtained by reacting sulfuric acid with saltpeter.

Hydrochloric acid can be obtained by heating sulfuric acid and table salt.

Since hydrochloric acid and nitric acid are both volatile acids, they only need to be collected in a tube.

Because of this relationship, both the nitric acid workshop and the hydrochloric acid workshop were built near the sulfuric acid workshop.

The problem of three acids was solved, and Zhao Xu stopped looking at the remaining preparation of caustic soda.

When caustic soda was making soap, he had already established a corresponding workshop.

He and Qu Sheng went directly to the workshop where soda ash was made.

At present, Yanzhou’s soda ash mainly relies on purchasing alkali ore from Yuzhou.

However, since the alkali mine is within the control of the Wang family, once there is a break-up, there will be problems with the supply of soda ash.

So, despite the cumbersome process of making soda ash, he let Qu Sheng establish it.

After all, he has always pursued preparedness.

"When preparing hydrochloric acid, sodium sulfate will be produced at the same time, and iron oxide will be obtained by calcining pyrite. Heating these two together with charcoal will produce soda ash." Qu Sheng looked at the busy craftsmen.

At this moment, there is calcined black powder in the workshop. The craftsman pours the black powder into water, then filters it with gauze, and then heats it outside to obtain white soda ash.

After explaining all the processes of three acids and two alkali, Qu Sheng breathed a sigh of relief.

This is the reason why King Yan handed him three acids and two salts in one go.

Because if you get one of the things, you can get the rest smoothly.

"Well, it's already looking good." Zhao Xu witnessed the whole process and was quite satisfied.

Although the preparation methods developed by Qu Sheng are extremely primitive.

Although the amount of preparation can be said to be large-scale, it is only relative.

I guess just looking at it is enough.

There is no way around this. Industrialization needs to be done step by step and cannot be achieved in one step.

However, with Wang Chong's steam engine put into use, Yanzhou will have the ability to manufacture complex machinery.

In the future, the output of all walks of life in Yanzhou will jump.

After inspecting the chemical workshop, Zhao Xu asked Qu Sheng to take good care of the injured students, and then went straight back to the government office.

At this time, the government meeting had just ended, and Liu Fu compiled the officials' summary of the infrastructure achievements during this period into a book and handed it to Zhao Xu.

"2.8 million acres of new farmland were added, 106 bridges were built, and a total of 336 miles of canals were dug..."

While Zhao Xu was flipping through the book, Liu Fu was mumbling on the side.

"This result has been achieved during this period, which is really good." Zhao Xu nodded in praise.

Before the Battle of Jinzhou, he resettled part of the people from Jinzhou and organized some into production camps.

Later, Ma Han drove millions of people into Yanzhou, and more than half of them were reorganized into production camps.

Therefore, the scale of production camps under the jurisdiction of the government is still very large.

At that time, he adopted this strategy in order to attract more people without being overwhelmed by the influx of people.

After all, the food he has hoarded is limited and he must allow them to be self-reliant in time.

So the production camp's work-for-relief organization emerged.

The government gave the refugees food, and the refugees worked in the fields under the unified jurisdiction of the government.

After that, they will allocate farmland to them and let them become free people on the land of Yanzhou.

Now, Liu Fu has given him a phased result.

Apparently his strategy is paying off.

"More than three hundred miles of canals were dug, so many?" Zhao Xu glanced sideways at Liu Fu, a little disbelieving.

Liu Fu said: "Back to Your Highness, there are many ditches here that are three or four meters wide, so there are many dug."

After a pause, he said proudly: "Furthermore, your highness learned and put the work points in the school to good use. In addition to letting the agricultural construction battalion participate in digging ditches, he also encouraged the local people to dig ditches and earn work points. After three years, They can exchange their work points for food.”

"You're just trying to get away with nothing." Zhao Xu glared at Liu Fu, "You're getting more and more courageous, but the people just believe it?"

Liu Fu chuckled and said, "It all depends on His Highness's prestige. The people now trust the government. Of course, there are some who are not happy, but the government did not force them."

Zhao Xu nodded, "Although this matter is a bit aggressive, the current environment around Yanzhou is still not optimistic. Extraordinary times require extraordinary measures. The people will be more miserable and tired now, and they will be kicked out by me. , will allow them to live a good life.”

Liu Fuxu gave the people a bad check, naturally because of the government's financial problems.

Although Yanzhou's business is very profitable, there are also many places where Yanzhou needs to spend money.

Liu Fu's policy will save the government a lot of expenses for at least three years, and the money will be spent wisely.

For example, building warships, upgrading industries, and fighting Beidi.

In short, the enemy he was bound to fight this time was timid, completely reversed the offensive and defensive momentum, and led Yanzhou into the Age of Discovery.

While the two were talking, a yamen servant informed Zhou Yi that he was outside the door asking for an audience.

"Let him come in." Zhao Xu said, it was he who ordered Zhou Yi to visit Yancheng.

From now on, Zhou Yi's fleet will play an important role in his campaigns.

Not long after, Zhou Yi walked in.

Zhou Yi is a little dark now. This is the result of being exposed to the sun for a long time at sea.

Showing his white teeth, Zhou Yi said: "Your Highness, I will come over this time and bring you a rare object. Please take a look at it."

After that, he took out a round object from his arms, held it in his hand and stretched it out in front of Zhao Xu.

Liu Fu glanced at it and shook his head, he had never seen this before.

But this thing was so ordinary that he wasn't very interested.

But when Zhao Xu saw this thing, he couldn't help but breathed quickly, and said anxiously: "How did you get this thing?"
