Otaku Engineer in Great Tang Dynasty Chapter 837: Take the mine, chance encounter!

Except that Li Zexuan took it for granted in this era of iron ore ownership, he did not think about the extraction of pyrite when he was in the workshop.

The composition of pyrite is mainly ferrous sulfide. What he thought at the time was to extract sulfur and iron from it through a series of chemical processes, but after he returned home, he calculated it carefully and found that the pyrite It is easier to extract sulfur, but it is too difficult to extract iron!

It's not that it can't be extracted, but it is difficult to make it out under the current conditions. Even if it can be made out, the cost will be too great and it is not worthwhile!

So if he wants to get a lot of iron, he needs some magnetite (the main component is Fe3O4).

However, in addition to extracting sulfur from pyrite, it is also an extremely important industrial raw material, which will be discussed later.

"What do you want iron ore for?"

Li Er is not very concerned about sulphur ore. Besides, the imperial court does not have much control over sulphur ore, but iron ore is different. In the early period of the Tang Dynasty, although the imperial court abolished the exclusive tax on salt and iron, basically All proven iron ore belongs to the imperial court. In principle, private ownership of iron ore is not allowed.

"Your Majesty, the kid's workshop is short of iron! The iron kid that can be bought near Chang'an City has all been bought, but it is still not enough!"

The address and the use of words are a deep knowledge. Li Zexuan calls himself a kid here instead of a minister or a minister, to show that he is talking to Li Er as a junior, not a minister, because he is now After all, the topic mentioned is a matter of merchants, and it is very inappropriate to use the status of courtier.

"Huh! It's not promising! Your kid really thinks your workshop is a treasure? Iron mine, I won't give it to you, because not only you lack iron, but the court is lacking iron now! You think it's yours. Is the workshop important, or is my Shaofu Supervisor and Beidu Military Weapon Supervisor important?"

(The Tang Dynasty promoted the system of three provinces and six ministries, and the military weapons workshops were under the management of the Ministry of Industry and the Ministry of War, and they were called Shaofu Supervisor and Beidu Military Equipment Supervisor respectively)

After listening to Li Er, he flicked his sleeves and lost his breath.

During the early Tang Dynasty, the Tang Dynasty adopted a military system. There were 574-800 Zhechong prefectures distributed throughout the country, and 627 were famous for examination. This number is variable, which means that the minimum number of records is 574, and the maximum number of records is 800. The Zhechong Mansion is divided into three classes, each with a strength of 1,200, 1,000, and 800. Therefore, in the early Tang Dynasty, there were about 800,000 soldiers in the whole country, of which about 260,000 in Guannei Dao were the main force of the army-Datang Sixteen Guards.

The weapons and equipment of these 260,000 people were manufactured by the Shaofu Supervisor and Beidu Military Equipment. The military equipment of the rest of the local state capitals was in charge of the local state capitals, but the iron they used was not It was allocated by the "central government"!

Such a huge consumption of ironware made the court's demand for iron ore very strong.

"Uh, your Majesty, you are misunderstood! The kid is not asking for the existing iron ore in Datang. The kid means that the kid is looking for iron ore. After finding it, can the kid send someone to mine the iron ore?"

Li Zexuan explained carefully.

Li Er raised his eyebrows in surprise, a little surprised and said: "Oh? Your kid will be good at geomantic omen and gold mining?"

In ancient times, the inverted bucket was called one of the eight gates outside the rivers and lakes, which is regarded as the use of feng shui techniques in exploring gold mines and other minerals. The craft of prospecting is called the ninth gate: the gate of gold mining. Because the people of Kinmen have served in the government for a long time, there are very few descendants. Whenever a good gold mine is found, it is a daily advance.

Li Zexuan is also a man of the Taoist school anyway, of course he has heard of gold mining, but how can he know this stuff? It seems that there is no such Feng Shui knowledge in his memory of this life. His confidence in prospecting is derived from the memory of his previous life! But I definitely can't say that to Li Er.

"Uh, influenced by the teacher, the kid knows a little bit about these things, a little bit about them!"

Li Zexuan's thoughts turned sharply, and then he said nonsense seriously.

Li Er looked at him twice, and then said after a while: "So, I grant you an iron ore! But at the same time, you have to help the court find a similar iron ore, and then your iron ore You don’t need to pay taxes to the court, you can mine at will, how about?"

Although the iron ore at this time was owned by the state, a large part of it was mined by the private sector. The "Old Tang Book · Official Records" records: "Every world produces copper and iron state government, listen to people As the emperor, Li Er still has a lot of "manipulation space" on it, and he can ensure that other officials cannot pick out the stab.

Old fox, Lao Li’s advantage is really not something ordinary people can take. Li Zexuan slandered in his heart. After considering it for a while, he nodded and said, "Thank you, Your Majesty! That sulfur mine..."

Li Er smiled triumphantly, and then said: "Sulfur mine, you are free! As long as you can find it, it belongs to you. I won't bother!"

Although he didn't know what Li Zexuan wanted to do with the sulphur mine, he didn't bother to bother about it. This thing is not an important national strategic material~IndoMTL.com~, it is just to give Li Zexuan the benefit of joining the Shibosi.

"Your Majesty, the minister will go all out to help the Hejian County King manage the Shibosi Department and increase revenue for the Datang Mansion Library!"

Such a result, although not particularly ideal, is acceptable to Li Zexuan. It is regarded as a contribution to the country. If the court has more iron, the army will have better weapons and the country will be stronger!

As for Shibosi's right-handed move, he doesn't need to go to Guangzhou to "take a shift" anyway, just use his brain, and it doesn't have much impact on his current life.

"Huh! Go away!"

Seeing Li Zexuan's appearance of "seeing a rabbit and immediately throwing an eagle", Li Er hummed angrily.

Grass, Lao Li is really disrespectful of people, kill the donkey! Li Zexuan felt a little unhappy, but he did take advantage of this incident, so he didn't get angry with Lao Li, arched his hand, and retired.

Hmph, this broken palace young master is not willing to stay!

Out of the Taiji Palace, Li Zexuan secretly gave Li Er a middle finger, and then walked towards the palace gate, preparing to go home.

"Brother Xiaoxuan!"

At this moment, there was a pleasant female voice beside him. Li Zexuan heard about his reputation, and saw Changle walking in lotus steps, making money, very dignified and elegant.

"Your Royal Highness!"

The reason for Changle's dignified appearance is that he is now in the palace and has to abide by the rules. Similarly, Li Zexuan also has to abide by the rules, so he honestly bowed his hands in courtesy.

"Brother Xiaoxuan is very quick to present. Changle is here to thank Brother Xiaoxuan! Thank you for speaking to Changle in the Chaotang Hall!

Changle backed away, came over quickly, and whispered, the little girl's eyes were like water, which made her look gentle.
