Otaku Engineer in Great Tang Dynasty

"Your Majesty, see you Yonganhou!"

In the afternoon, in the Ganlu Hall, a servant came in and bowed.

In other words, after Li Zexuan came out of the workshop, he didn't even have time to eat lunch, so he came to the palace to look for Li Er.

Can be considered enough.

"Let him in!"

Li Er faintly smiled and said.

After a while, Li Zexuan walked in from outside, and then saluted Li Er: "The minister, see your majesty!"

"Well, no gift!"

Li Er nodded, and then said: "The kid is nestling in Yunshan all day long. Why is there time to enter the palace to see me today?"

This is just asking!

But he also had to ask knowingly, if he directly told Li Zexuan's intentions, Li Zexuan would definitely think that he was being watched, and there would be a rift between the monarch and his subjects. Old Li is not that stupid!

Li Zexuan arched his hands and said: "Return to Your Majesty, the minister is here today to ask your Majesty for the right to mine a vein. I hope your majesty will grant you permission!"

A while ago, he broke control of the city and put down the rebels of the Cui family. In addition to promoting Li Zexuan’s official position, Li Er also awarded Li Zexuan the right to mine three mineral veins, but he did not specify which three mineral veins. Basically, it is equivalent to Lao Li writing a blank check that can be filled out at will. Today, Li Zexuan just wants to write the name of the Lanjia Volcano vein on this check!

When Li Er heard this, he couldn't help but laugh, he smiled: "Yo~! This is to collect debts from me? Tell me, what kind of vein? Gold, silver, or copper?"

Li Zexuan bowed and said, "My Majesty, the minister does not want gold mines, nor silver mines and copper mines. The minister only needs a vanadium-titanium magnetite in Zhangzhou, Jiannan Road, and I hope your majesty will allow it!"

After the Qin era destroyed Ba and Shu, the system of prefectures and counties was implemented in Sichuan, and Ba County and Shu County were established in the original Bashu area. In the first year of Zhenguan, Li Er abolished the system of states and prefectures, changed Yizhou into Jiannan Road, and his office was located in Chengdu Mansion.

As one of the ten Taoisms in the world, Jiannan Dao mainly refers to more than 30 prefectures and hundreds of counties in the Bashu area!

Li Er wondered: "Vanadium-titanium magnetite? What kind of ore is this? What is it for? Why have I never heard of it?"

Although he heard Zhao Song say that Li Zexuan sent people to Bashu to look for mines, he really didn't know what mine Li Zexuan was looking for, and he didn't even know what vanadium-titanium magnetite was!

Li Zexuan said, "Your Majesty, in the minister’s workshop, there is a great need for a catalyst called vanadium pentoxide. With this kind of thing, the minister’s workshop can produce sulfuric acid in large quantities! Sulfuric acid is the "three acid" in engineering. One of the "two alkalis" is extremely versatile. It can be called the cornerstone of my Datang industry without exaggeration! And from vanadium-titanium magnetite, that kind of catalyst can be extracted!"

Although Li Er did not conduct in-depth research on "Chemistry", it was the first time that he saw Li Zexuan introduce something to him so solemnly, so he couldn't help but pay more attention to this so-called vanadium-titanium magnetite.

"I don't know much about engineering. Can you tell me what is the purpose of this sulfuric acid? And what else can vanadium ore be used for besides producing sulfuric acid?"

If you don’t understand, just ask, this is what makes Li Er different from other emperors. In terms of his mind, few emperors can compare with him!

Furthermore, in the land of Bashu, there are many tycoons and tribes, and the various forces are intricate. Old Li has to ask the matter clearly, so as to weigh the value of this vanadium mine in Bashu is not worth mining!

Li Zexuan thought for a while, picked up some things that Li Er could understand, and replied: "Your Majesty, sulfuric acid has a very wide range of uses. Going farther, this thing can make more powerful gunpowder and refine stone paint. , And to make fertilizers that can make crops more high-yield. Closer to say, sulfuric acid can be used to refine copper, so that the purity of copper is higher. In the future, the generators in the Bahe Hydropower Station will need refined copper! With sulfuric acid, Chen can also make batteries!"

Regarding stone lacquer, this thing is oil. Before Shen Kuo's "Mengxi Bi Tan", there was a record of oil in the "Book of Pre-Han"!

Li Er heard this, with a look of shock, he murmured: "A more powerful gunpowder? There are even more powerful gunpowder in this world? And there is fertilizer that can make crops more productive? And, the battery that I just mentioned, and What is it?"

All these things Li Zexuan said were so incredible to Li Er, he couldn't help but be shocked!

Li Zexuan smiled and replied: "Your Majesty, the gunpowder presented by the minister is the most primitive, simplest, and of course the smallest kind of gunpowder. The gunpowder that the minister just said is more than dozens of times more powerful than it. A hundred catties can destroy half a city! As for fertilizers that can make crops more productive, it can probably increase crop yields by 30-40%!

However, it is impossible to make strong gunpowder and fertilizer only with sulfuric acid, and the industrial base of the workshop needs to be improved! As for the battery, after having sulfuric acid, you can start manufacturing immediately. Your Majesty should know the battery that the minister made for the telegraph. Compared with the previous battery, the battery has more power. The storage battery can ensure that the telegraph can keep communicating with the rear for a long time! "

After listening to Li Er, he couldn't help being greatly moved. Whether it was strong gunpowder or a battery, he wanted it! So he smiled and said:

"Good! Good! Good! This battery must be built as soon as possible! As for the strong gunpowder, don't worry, it is enough to have another kind of gunpowder. Besides, I am still very confident in the combat effectiveness of my Datang army. of!"

Li Zexuan smiled and said: "Your Majesty Shengming! The minister also believes that with His Majesty's wise and magical power, Datang's army will surely sweep the four directions and majestic world! In addition, the use of vanadium ore can be used in addition to the production of sulfuric acid. Come to cast the magic weapon!"

"The magic weapon? What kind of magic weapon?"

Li Er suddenly wondered.

Li Zexuan replied: "Your Majesty, the workshop can already produce high-quality steel on a large scale. If steel is a tiger, then vanadium is the wing. The vanadium content in steel is like a tiger. You only need to add a few percent of vanadium to the steel. The elasticity and strength of steel are greatly increased, and the resistance to wear and burst is better. It is resistant to high temperature and extreme cold. If you use this vanadium steel to make a sword, although it can not be said to cut iron like mud, the difference is not far. !"

"Good! What a magical soldier!"

Li Er suddenly saw the fascinating face, he said with some excitement:

"I have previously promised the right to mine three mineral veins. Since this vanadium ore is so important to me, it doesn’t matter if I give it! And I see how confident I am today, could it be that I found the vanadium ore in Zhangzhou, Jiannan Road? It~?"

Li Zexuan was overjoyed when he heard the words, and hurriedly replied: "Returning to your majesty, at the beginning of this year, the minister sent servants to find vanadium mines in Shu area. Fortunately, the servants of the minister survived their lives. On a mountain in Shizhou, they found a large number of Vanadium-titanium magnetite ore, by virtue of this ore, can definitely be used by Datang for hundreds of years! It's just..."

Li Er smiled in his heart, and secretly said that he finally got to the point. He smiled lightly and said, "It's just what?"

Li Zexuan bowed and said, "Your Majesty, according to the servants of the minister, this mountain was mistaken for the sacred mountain by the local Qiang people. They do not allow outsiders to invade the sacred mountain, let alone mining from above! So..."

Li Er frowned and said, "Sacred Mountain? What is there to say?"

"His Majesty, this is just nonsense! The local Qiang people found that the mountain range is very attractive to the swordsman, so they feel that it is magical, but in fact it is only the powerful contained in the vanadium-titanium magnetite in the mountain. That’s all for magnetism! But the Shu area is closed, and most of the local people believe in the power of ghosts and gods, so it’s not easy to explain to them! For this reason, the servants of the minister and the family were almost killed by the local Qiang people, please The Lord is the master of the minister!"

Li Zexuan bowed and said in a deep voice.

"Qiang people!"

Li Er's face gradually became gloomy. After a moment of silence, he slowly said: "When the heroes competed in the Central Plains, the rich and powerful surnames and other local forces in Bashu mostly merged with the county officials, protecting the environment and defending themselves. The change of the situation. After my father took control of Bashu, "I told the counties and counties to the east from Shangluo, and from the south to Bashu. The county magistrates and the thieves Qushuai, the chief Diqiang, please surrender, and there is a secretary. Resume the book, count in hundreds every day."

In the face of strong military pressure, the surnames of the Bashu Hao clan have joined our Datang. Regarding these surrendered places, the imperial court mainly adopted a policy of combining enlightenment and power, on the one hand to prevent them from sitting on a large scale in the future, on the other hand, to prevent them from becoming unhappy and raising rebellion!

Hundreds of years ago, Liu Bangxing was in Bashu. In the Chu-Han War, the Bashu area at the rear not only provided a continuous force supplement for the Han army, but also provided strong logistical support for the war. Where is the Han army? There is food and munitions provided by Bashu. The five-year battle between Chu and Han, the battle of Gaixia, embarrassed on all sides, Xiang Yu Wujiang cried himself, Liu Bang was the emperor, opening the history of the two Hans for four hundred years!

Bashu contributed all the energy to Liu Bang's imperial industry, supported the war for several years with almost one place, and made indelible feats for the founding of the Han Dynasty. Therefore, it can be said that Bashu was the land of Longxing in the Han Dynasty. Therefore, after Liu Bang came to the throne, he attached great importance to the land of Bashu. He regarded central Sichuan as a land exclusively occupied by the court, and was directly under the jurisdiction of the Han court, and never entrusted the vassal kings in the land of Shu!

In fact, the emperor and Zhen have always paid great attention to the governance of Bashu. In order to balance the powerful forces in Bashu and to maintain the long-term stability of the land of Bashu, I called on the leaders and children of Bashu. Introduce, but really take it seriously. On the other hand, I sent the queen’s uncle to the land of Bashu to serve as the chief historian of the governor of Yizhou. I asked him to govern the land for me, so that the people of the land of Shu will return to me as soon as possible. Datang!

In addition, I also intend to change Ke'er to the king of Shu, and grant the governor of Yizhou, the military governors of Yizhou, Mian, Jian, Jia, Ling, Ya, Mei, Meng, Qian, and Qiong Shizhou, and they will also supervise the military. Nanning and the Huidu Mansion totaled 36 states. When he was a few years older, I sent him to Shu to take office to show that I attach importance to Shu!

Now that there is such an important mineral vein in the Shu area, then I will make an order to let Yizhou Metropolitan Governor Shi personally negotiate with the Qiang people. After the negotiation is completed, send someone to mine the vein there! "

The uncle of the eldest-grandson empress Li Er mentioned, the Governor of Yizhou Metropolitan Government, was Gao Shilian and later the prime minister of the Tang Dynasty!

After listening to the old Li Xuxu talking about it for so long, Li Zexuan has a general understanding of the current situation in the Bashu land. Of course, he did not expect that Li Er actually took Li Ke from the King of Han under this situation. The title was changed to the king of Shu. However, according to the official history, even if he did not appear, Li Er would be named the king of Shu this year, that is, in the second year of Zhenguan.

History is always surprisingly similar sometimes!

At this moment, Li Zexuan arched his hands:

"Your Majesty, when negotiating with the Qiang tribe, it is better to be soft than hard. If Gao Changshi's negotiation is blocked, the minister can make suggestions for it!"

Li Er couldn't help but smile and said, "Oh? What good strategy can't be done?"

Li Zexuan bowed and said, "The Qiang people misunderstand that the mine is a sacred mountain. The minister will send someone to explain to them clearly! Moreover, once the mine is mined, it will bring endless benefits to the local Qiang people. The most intuitive benefit is They earn more money every year! Although Qiang people live in tribes, I believe no one of them will dislike money and the exquisite products of the Central Plains?"

Li Er understood, Li Zexuan's intention was to lure him into using a mine to feed the people around him. It was indeed a good idea!

"Haha! This is also very good! I will send an order to the queen's uncle later, let him deal with this matter at his discretion, and when necessary, I will ask about it again~!"

Li Er nodded and smiled.

"Thank you, Your Majesty~!"

Li Zexuan arched his hands contentedly.

……………………………

After coming out of the palace, Li Zexuan went straight back to Yunshan. When he passed by Yanhuang Academy, he thought for a while, but turned around and walked in.

Called Li Ke out of the classroom and brought it to the office. Li Zexuan sat on the sofa and smiled slightly and said, "Xiao Ke, you should have learned all the financial management knowledge handed over to the teacher?"

Li Ke arched his hands and said: "Shanchang's knowledge~www.ltnovel.com~ If you have not learned enough in case, how can you say that you are almost done?"

Li Zexuan couldn't help smiling and said, "Hehe! The kid should be humble! Okay, I got a teacher today. I have something to say."

"Shanchang, please speak!"

Li Ke was sitting in distress, looked at Li Zexuan, and made an earful gesture.

Li Zexuan nodded and said in a deep voice: "Today I went to the palace as a teacher. I heard what the saint said that he intends to change the title to the king of Shu, grant the governor of Yizhou, and manage the affairs of the 36th state of Bashu!"

Li Ke was taken aback when he heard the words. He said in a panic: "Shan Chang, is the father going to send me to the place of Shu soon?"

He is now learning financial and economic knowledge from Li Zexuan in Yanhuang Academy, which he has never heard before. He is very happy and fulfilling, and he doesn't want to leave so soon!
