"Your Majesty, the Marquis of Yongan asks to see you!"

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

In other words, after Li Zexuan left the workshop, he didn't even have time to eat lunch, so he ran to the palace to find Li Er.

It's also enough.

"Let him in!"

Li Er smiled lightly and said.

After a while, Li Zexuan walked in from the outside, and then saluted Li Er: "I see your Majesty!"

"Well, no gift!"

Li Er nodded, and then said: "You kid has been nesting in Yunshan all day long, why do you have time to enter the palace to see me today?"

This is a well-informed question!

However, he also had to ask knowingly. If he directly stated Li Zexuan's intention, Li Zexuan would definitely think that he was being watched, and there would be a rift between the ruler and the minister. Old Li is not that stupid!

Li Zexuan cupped his hands and said, "Go back to Your Majesty, this minister is here today to ask Your Majesty for the right to mine a ore vein, and I hope Your Majesty's permission!"

A while ago, Guancheng was smashed and the rebels of the Cui family were wiped out. In addition to promoting Li Zexuan's official position, Li Er also awarded Li Zexuan the right to mine three ore veins, but he did not specify which three ore veins were at that time. , is basically equivalent to Lao Li writing a blank check that can be filled in at will, and today, Li Zexuan just wanted to write the name of the vein of Lanjia Volcano on this check!

Hearing this, Li Er couldn't help but laugh. He smiled and said, "Yo~! Are you here to collect debts from me? Tell me, what kind of ore do you want? Gold mine, silver mine, or copper mine?"

Li Zexuan bowed and said: "Go back to Your Majesty, I don't want gold mines, nor silver mines or copper mines. I only want a vanadium-titanium magnetite mine in Zhangzhou, Jiannan Road, and I hope Your Majesty's permission!"

After Qin destroyed Ba and Shu, the county system 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 state and county system, changed Yizhou to Jiannan Road, and the administrative office was located in Chengdu Prefecture.

As one of the ten roads in the world, Jiannan Road mainly refers to more than 30 states and hundreds of counties in the Bashu area!

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

Although he heard from Zhao Song that Li Zexuan had sent someone to look for mines in Bashu, he really didn't know what kind of mines Li Zexuan was looking for, let alone what vanadium-titanium magnetite was!

Li Zexuan cupped his hands and said: "Your Majesty, in the workshop of the minister, there is a great need for a catalyst called vanadium pentoxide. With this kind of thing, the workshop of the minister can produce sulfuric acid in large quantities! Sulfuric acid is the "three acid" in engineering. One of the "two alkalis", it has a wide range of uses. It is no exaggeration to call it the industrial cornerstone of my Datang! And in vanadium-titanium magnetite, that kind of catalyst can be extracted!"

Although Li Er had not conducted in-depth research on "Chemistry", it was the first time he saw Li Zexuan introduce the same thing to him so solemnly, so he could not help but attach importance to the so-called vanadium-titanium magnetite.

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

If you don’t understand, ask, this is where Li Er is different from other kings. In terms of mind and tolerance, few emperors can compare with him!

Furthermore, in the land of Bashu, there are many noble families and tribes, and the forces of all parties are intricate and complicated. Old Li has to ask the matter clearly, so as to weigh whether this vanadium mine in Bashu is worth mining!

Li Zexuan thought about it, picked up some things that Li Er could understand, and replied, "Your Majesty, sulfuric acid has a very wide range of uses. In the long run, this thing can make more powerful gunpowder, and it can also refine stone paint. , as well as the manufacture of fertilizers that can make crops more productive. In the near future, sulfuric acid can be used to refine copper to make the copper more pure. In the future, the generators in the Bahe Hydropower Station will need refined copper! Sulfuric acid, I can also make batteries!"

Regarding stone lacquer, this thing is oil. Before Shen Kuo's "Mengxi Bi Tan", there were records about oil in "Book of the Former Han Dynasty"!

Hearing this, Li Er was shocked, and he muttered: "Gunpowder with more power? There is more powerful gunpowder in this world? And fertilizer that can make crops more productive? Also, the battery you just mentioned, What else is it?"

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

Li Zexuan replied with a smile: "Your Majesty, the gunpowder that the minister gave earlier is the most primitive, the simplest to make, and of course the least powerful, and the gunpowder that the minister just said is more than ten times more powerful, as long as A hundred kilograms can destroy half a city! As for the fertilizer that can make crops more productive, it can probably increase the yield of crops by 30-40%!

However, it is impossible to create strong gunpowder and fertilizer with sulfuric acid alone, and the industrial base of the workshop needs to be more perfect! As for the accumulator, once you have sulfuric acid, you can start to manufacture it immediately. Your Majesty should know that the battery made by the previous ministers for the telegraph. Compared with the previous kind of battery, this accumulator has more sufficient power. The battery can ensure that the telegraph can maintain communication with the rear for a long time! "

After listening to Li Er, he couldn't help but be very moved. Whether it was strong gunpowder or batteries, he wanted it! So he smiled and said:

"Good! Good! Good! This accumulator must be built as soon as possible later! As for the strong gunpowder you mentioned, don't worry about it, another type of gunpowder is enough. Besides, I still have a lot of combat effectiveness for my Tang army. confident!"

Li Zexuan smiled and said, "Your Majesty is holy!

It is believed that with the help of His Majesty's wise and martial arts, the army of the Tang Dynasty will be able to sweep the Quartet and the world with majesty! In addition, regarding the use of vanadium ore, in addition to making sulfuric acid, it can also be used to cast magic weapons! "

"Divine Soldier? What Divine Soldier?"

Li Er suddenly wondered.

Li Zexuan replied: "Your Majesty, at present, the workshop can produce high-quality steel on a large scale. If steel is tiger, then vanadium is the wing, and vanadium in steel is like adding wings to the tiger. Just add a few percent of vanadium to steel, and you can The elasticity and strength of the steel are greatly increased, and the wear resistance and burst resistance are better, and it is resistant to high temperature and extreme cold. !"

"Good! What a magic soldier!"

Li Er suddenly looked fascinated, and he said excitedly:

"I promised you the right to mine three ore veins before. Since this vanadium mine is so important to you, it's okay to give it to you! Besides, I see that you look confident today. Could it be that you found it in Zhangzhou, Jiannan Road? Do you have the vanadium ore you want~?"

Li Zexuan was overjoyed when he heard the words, and quickly replied: "Go back to your majesty, the minister sent a servant to look for vanadium mines in Shu at the beginning of this year. Fortunately, the servant of the servant was not humiliated. On a mountain in Zhangzhou, a large number of Vanadium-titanium-magnetite ore, with this ore, can definitely be used for the needs of the Tang Dynasty for hundreds of years! It's just..."

Li Er smiled in his heart, and the secret thought finally got to the point. He smiled lightly and said, "Just what?"

Li Zexuan bowed and said, "Your Majesty, according to the servants of the minister, this mountain was mistaken for a 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's there to say here?"

"Go back to your majesty, this is just nonsense! The local Qiang people found that the mountain had a strong attraction for swordsmen, and they felt that there was a magical power, but in fact it was just the powerful vanadium-titanium magnetite contained in the mountain. Magnetism is enough! But Shu is closed, and most of the local people believe in the power of ghosts and gods, so I am afraid it is not easy to explain to them! For this reason, the servants and family members of the minister were almost killed by the local Qiang people. Please also ask The sage is the master of the subject!"

Li Zexuan bowed and said solemnly.

"Qiang people!"

Li Er's face gradually darkened, and after a moment of silence, he slowly opened his mouth and said: "When the heroes were competing in the Central Plains, the wealthy clans and other local forces in Bashu often joined forces with the county officials to protect their borders and defend themselves. Changes in the situation. After my father took control of Bashu, he issued a book to all the counties and counties, so from Shangluo in the east, Bashu in the south, the county magistrates and the thieves Qu Shuai, the chiefs of Diqiang, vying to send their children to the meeting to ask for surrender, there are Sifu Books, hundreds of days.

In the face of strong military pressure, the great surnames of the Bashu clan have all attached themselves to the Tang Dynasty. Regarding these local tyrants who surrendered, the imperial court mainly adopted a policy of combining favor with power.

Hundreds of years ago, Liu Bang flourished in Bashu. During the Chu-Han War, the Bashu area as the rear area not only provided a steady stream of troops for the Han army, but also provided strong logistical support for the war. Wherever there is the Han army, there will be supplies of food and grass provided by Bashu. The five-year battle between Chu and Han, the battle of Gaixia, the embarrassment on all sides, Xiang Yu's suicide on the Wujiang River, and Liu Bang being the emperor, opened the 400-year history of the Han Dynasty before and after!

Bashu contributed all the energy to Liu Bang's imperial industry, almost supported several years of wars with one place, and made indelible contributions to the founding of the Han Dynasty. Therefore, it can be said that Bashu is the land of Longxing of the Han Dynasty. Therefore, after Liu Bang came to the throne, he attached great importance to the land of Bashu. He directly regarded Chuanzhong as the exclusive territory of the imperial court, and was directly governed by the Han court.

In fact, the father and I have always attached great importance to the governance of Bashu. In order to balance the power of all parties in Bashu, and to maintain the long-term stability of Bashu, I called the children of Bashu leaders on the one hand, and gave them what they could. On the other hand, I sent the queen's uncle to the land of Bashu to serve as the chief secretary of the governor's office of Yizhou. I asked him to manage the land of Shu for me, and let the people of the land of Shu return to me as soon as possible. Datang!

In addition, I recently planned to change the title of Ke'er to the king of Shu, and to grant him the commander-in-chief of Yizhou. , Nanning, and the Governor's Mansion in total thirty-six prefectures. When he is a few years older, I will send him to Shudi to take office to show the importance I attach to Shudi!

Now, since there is such an important ore vein in Shu, I will decree that the governor of Yizhou will come forward to negotiate with the Qiang people on your behalf. After the negotiation is completed, you can send someone to mine the ore there! "

The uncle of Empress Zhangsun and the chief history of the Yizhou Grand Governor's Office mentioned by Li Er was Gao Shilian, who was also the later Prime Minister of the Tang Dynasty!

After listening to Old Li ramble on for so long, Li Zexuan had a general understanding of the current situation in the land of Bashu. Of course, he did not expect that Li Er actually transferred Li Ke to the King of Han under such circumstances. The title was changed to King of Shu, but according to the official history, even if he did not appear, Li Er would have named Li Ke the King of Shu this year, the second year of Zhenguan.

History is sometimes surprisingly similar!

At this moment, Li Zexuan cupped his hands and said:

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

Li Er couldn't help laughing and said, "Oh? What other good plan can you have?"

Li Zexuan bowed and said: "The Qiang people mistakenly regard the mine as a sacred mountain, and the minister will send someone to explain it to them at that time! Moreover, once this mine is mined, it will bring endless benefits to the local Qiang people, the most intuitive benefit. It's that they make more money every year! Although

The Qiang people live in tribal groups, but I believe that no one of them will not like money and the exquisite commodities in the Central Plains, right? "

Li Er understood, Li Zexuan was planning to lure him to feed the surrounding people through a mine, which was indeed a good idea!

"Haha! That's great! I'll pass the order to the queen's uncle later, and let him handle the matter as he sees fit. When necessary, I'll ask you for advice~!"

Li Er nodded and smiled.

"Thank you, Your Majesty~!"

Li Zexuan cupped his hands contentedly.

…………………………

After coming out of the palace, Li Zexuan went directly back to Yunshan Mountain. When passing by Yanhuang Academy, he thought about it, turned around and walked in.

Calling Li Ke out of the classroom and taking him to the office, Li Zexuan sat on the sofa and smiled slightly: "Xiao Ke, you should have learned almost all the financial management knowledge given to you by the teacher, right? "

Li Ke cupped his hands and said: "The mountain chief's knowledge, if you have not learned enough, how can you dare to say that you have learned almost?"

Li Zexuan couldn't help laughing and said, "Haha! You're still modest! Well, I'm looking for you for my teacher today. I have something to talk to you about."

"Sir, please speak!"

Li Ke sat upright, looked at Li Zexuan, and made a deaf ear.

Li Zexuan nodded and said solemnly: "I went to the palace for my teacher today, and I heard what the sage said, I plan to change you to the king of Shu, grant you the governor of Yizhou, and manage the affairs of the thirty-six states of Bashu. Prepare yourself mentally!"

Hearing this, Li Ke was taken aback, and he said in a panic, "Shan Chief, do you mean that the emperor is about to send me to Shu to take up office?"

He is now studying with Li Zexuan in Yanhuang Academy the kind of financial and economic knowledge he has never heard before. He is very happy and fulfilling. He doesn't want to leave so soon!
