"Young Master, why are you here?"
Faubert saw Li Zexuan in the workshop of the Strange Interest Pavilion and quickly greeted him.
Li Zexuan stopped in his tracks, but his eyes swept across the courtyard. As he looked, he replied,
"Faubert, I heard that the vanadium ore from Sichuan has been transported back, so I came to take a look! Where is it? How much is there in total? "
Faubert said with a smile, "Young Master, the ore has been transported to the steel mill. I know that you value this kind of ore, so I didn't dare to leave it outside!"
Li Zexuan smiled and was about to speak when another person came into the workshop.
"The vanadium ore is here, where is it … Hey! Yamachō, you're here too? "
It was Wang Ji.
Vanadium was a catalyst necessary for mass production of concentrated sulfuric acid. Not only was Li Zexuan concerned, but Wang Ji had also been waiting for the vanadium ore from Sichuan to be transported back.
Li Zexuan nodded with a smile and said, "Yes! Mr. Wang, you're quite fast, aren't you? "
Wang Ji said happily, "Hey! As the leader of the Chemistry Department, of course I have the responsibility to help the academy develop new chemical raw materials. I've been looking forward to this vanadium ore for a long time! "
"Young Master, the guards transporting the ore this time are all Qiang people from Sichuan. They also brought two letters, saying that their Young Master Ke gave them to you!"
Uncle Fu said as he took out two lacquered letters from his bosom and handed them to Li Zexuan.
"Young Master Ke?"
Hearing this name, Li Zexuan was a little confused. After a moment, he came back to his senses and couldn't help but laugh. "It should be Ke Shiqing, right? Oh, it seems that this young man is doing well in the Qiang tribe! He's even called Young Master! "
Wang Ji stroked his beard and smiled proudly. "The students of our Yanhuang College will always be the center of attention no matter where they go. This old man has some impression of Ke Shiqing. He is indeed a diligent and studious child ~!"
The old man's current appearance was exactly the same as those old teachers in modern times when they found out that their students had made a name for themselves. They were obviously very pleased with themselves, but their mouths and faces were still rather reserved and self-restrained. Seeing this, Li Zexuan couldn't help but want to laugh.
"Haha! Let's go! Mr. Wang, why don't we take a look at the quality of this batch of vanadium ores? "
Li Zexuan saw that Faubert was secretly curling his lips at the arrogant Wang Ji, so he quickly pulled Wang Ji towards the steel mill.
"Whoa! With so many ores, you should be able to extract a lot of vanadium, right? "
Walking into the yard of the steel mill, they saw a large pile of light gray ores of various sizes under a cloth shed. At a glance, there were at least 500 kilograms. Wang Ji's eyes widened and he couldn't help but exclaim in surprise.
Li Zexuan walked closer and casually picked up a piece of ore from the pile. He brought it closer to him and looked at it seriously for a moment.
"Mm! The quality is very good! Mr. Wang, this pile of vanadium titanomagnetite can produce at least 300 kilograms of vanadium. With so much vanadium, it should be enough to cover the recent consumption of sulfuric acid in the workshop! You'll have to work a little harder these days. Get the craftsmen in the workshop to modify the boiler and build a small vanadium workshop. Then build a workshop for sulfuric acid production. Quickly produce a batch of concentrated sulfuric acid. I have great use for it! "
Wang Ji replied excitedly, "Yes! Yamachō! "
Even if Li Zexuan didn't say it, he would have taken the initiative to volunteer. After all, it wasn't easy to get so many vanadium titanomagnetite ores. If he couldn't refine it himself, he would grow hairs on his back!
"Oh! That's right! Yamachō, according to the textbook 'Chemistry', sulfuric acid is highly corrosive. It can react with iron to form ferrous sulfate and hydrogen. So, what will we use to store concentrated sulfuric acid in the future? "
Wang Ji paused for a moment and suddenly said.
Li Zexuan thought for a moment and replied with a smile, "Mr. Wang, dilute sulfuric acid can dissolve iron and release hydrogen. The reaction mechanism is that the hydrogen ions in the dilute sulfuric acid reacts with iron. But when concentrated sulfuric acid comes into contact with iron, it will not, or very rarely, react with iron.
Because concentrated sulfuric acid has a very high purity, sulfuric acid exists in the form of covalent compounds, not ionic compounds. When its purity is high, it will ionize very little hydrogen ions, almost none. So, it won't corrode ironware. Instead, it will passivate the iron and form a dense oxide film on the surface of the iron. This oxide film is very dense and prevents concentrated sulfuric acid from entering the iron to continue the reaction.
However, although concentrated sulfuric acid can be stored in carbon steel, it is best to store it at room temperature and pressure. This way, the corrosion rate of carbon steel will be the lowest. This is because the hot concentrated sulfuric acid will also react with iron. In order to ensure the safety of concentrated sulfuric acid storage, we need to use horizontal storage tanks and build leakproof walls around the tanks.
The sulfuric acid storage room must prohibit fireworks because there will be a small amount of dilute acid on the surface of concentrated sulfuric acid that will react with iron to produce hydrogen. When the hydrogen comes into contact with fire, it will explode. In terms of safety, Mr. Wang, you must be very careful. Safety in production is more important than Mount Tai! I don't want any safety accidents to happen in our workshop! "
At the end of his speech, Li Zexuan's face was very dignified.
Even in modern times, chemical factories were the places where safety accidents were most likely to occur. Either the leakage of toxic chemical products or the explosion caused by flammable substances, no matter which one it was, it would cause great harm to the surrounding people!
It was precisely because of this that Li Zexuan had repeatedly warned Wang Ji in such a serious manner!
Wang Ji also understood the pros and cons of this matter, so he cupped his hands together. "Don't worry, Mountain Elder. This old man will definitely put safety first and conduct safety training for the craftsmen on a regular basis. At the same time, I will also link their monthly salary to the safety of production. This way, everyone will strictly abide by the safety regulations!"
Li Zexuan's eyes lit up. He nodded and said, "Okay! Mr. Wang, this is a good idea. When you go back, discuss with Faubert on how to implement this salary system as soon as possible. Those craftsmen who follow the regulations will be paid more. Those who violate the safety regulations will have their salary deducted. We must make all the craftsmen in the workshop pay attention to this! "
"Yamachō, no problem! This old man knows the importance of this matter! "
Wang Ji nodded and replied.
… … …
After telling Wang Ji to pay attention to safety, Li Zexuan asked Wang Ji to produce a batch of concentrated sulfuric acid as soon as possible because he was going to make a battery!
In addition, the catalyst used in sulfuric acid production, vanadium, could also be used as a catalyst for cracking oil in the future. It could be said that this was killing two birds with one stone!
After leaving the workshop and returning to the courtyard, Li Zexuan took out the letters that Faubert gave him. On one of the envelopes, it was written "Yamachō Only" and the other "Mother Only". Li Zexuan opened the letter that Ke Shiqing wrote to him and began to read it carefully.
"It has been almost a month since I left Yunshan. Shiqing misses the people and things in the Academy, but Shiqing is even more grateful to Yamachō for giving me this opportunity to benefit the people in my hometown. Now, the road from Guanzhong to Shu is being built.
The imperial court has also sent a large number of officials with large amounts of money to support the construction of the people in Shu.
A group of merchants from Chang 'an City also set up shop in Chengdu Prefecture. They brought many new things that the local people had never seen before. The commerce in the center of Sichuan was thriving.
The mining of vanadium titanium magnetite allowed the local people to work in the mines to earn money. In less than half a month, the wages that each miner received were almost equivalent to three to four months of their previous income!
According to Yamachō's instructions, Shiqing adheres to the principle of safety first. I would rather mine the vanadium ore slowly to ensure the safety of the miners. So far, there has not been a single casualty!
Oh, right, Datang Daily has also opened an office in Shu. Now, the people in Shu are starting to get used to reading the newspaper every morning! Yesterday, I read in the newspaper that Yamachō has invented a new type of water wheel and released the blueprint to the world. Shiqing is proud to be a student of Yamachō!
In addition, His Highness the King of Shu ordered people to set up a branch of Yanhuang Bank in Shu. With the help of Senior Official Gao, the people and merchants in Shu have slowly begun to accept the new currency, Tang Yuan, and the people who use copper coins are gradually decreasing!
With the help of the Sanbao brothers, I brought the curved plough, Tang Dynasty Dictionary, bicycles, coal stoves, honeycomb briquettes, and other things that are beneficial to the people to Shu. With the support of Senior Official Gao, I opened the people's wisdom, promoted agriculture, and promoted business!
Now, Shu is undergoing earth-shaking changes. How lucky I am to be able to witness the prosperity of my hometown and the people's lives are getting better! I remember Yamachō once said, 'The knowledge on paper is shallow, but the knowledge must be experienced.' In the process of leading the people in my hometown to become rich, I understand the true meaning of this sentence!
Some things seem simple, but when you really do it, you will often encounter many unexpected difficulties. Fortunately, I have survived those difficulties. Now, I have become the Young Master Ke in the hearts of the people in Shu Province!
Yamachō, rest assured, I will not be arrogant in victory and will not be discouraged in defeat. I will lead the people in Shu Province to become rich. I will not lose face for Yamachō and will not smear the reputation of Yanhuang College!
I, Ke Shiqing, wish Yamachō success in everything and good health! "
"Husband, what are you looking at? Why are you so happy? "
Li Zexuan had just finished reading the letter and was about to sigh when Han Yuxi walked over and asked softly with a smile.
"Haha! Nothing! It's a letter written by a student of the Academy! "
Li Zexuan said with a smile as he pulled his wife to his side.
"A letter from a student? Aren't all of your students in the Academy? Why do they need to write to you? "
Han Yuxi frowned her beautiful willowy eyebrows and asked doubtfully.
Li Zexuan smiled and asked, "Wife, do you still remember the student named Ke Shiqing who volunteered to go to Shu Province?"
Han Yuxi frowned and thought for a moment, then said with a smile, "Oh! I remember now. His mother came to Cloud Mountain to deliver a letter to you! "
"En! It's him! This child is now doing well in Shu Province. As a teacher, I am very gratified to see it! "
Li Zexuan handed the letter to Han Yuxi and smiled.
"I see! I was wondering why my husband was smiling so happily! "
Han Yuxi took the letter, swept it aside, and said happily, "My husband is benefiting the people of Lantian County, but Ke Shiqing is benefiting the people of his hometown. This student is very similar to you, my husband! The Yanhuang Academy has produced many talents. In the future, if the students of the academy can be like Ke Shiqing and use their own knowledge to bring prosperity to the world, then my husband will truly have students all over the world and your name will go down in history! "
Li Zexuan couldn't help but feel excited when he heard this. He patted his wife's shoulder and sighed. "That's why Yanhuang College is the greatest wealth and support of the Tang Empire and our family! Instead of studying the art of intrigue and mingling in the imperial court, it's better to open the school and teach thousands of students what I have learned. In the future, I will have students all over the world. Even if you are the Prime Minister or the Emperor, you will have to respect me! "
These were the words from the bottom of his heart!
When Li Zexuan first established the Yanhuang Academy and spread the knowledge of engineering, it was to benefit the people of the world and to seek a little bit of welfare for the toiling masses of this era. However, at the same time, Li Zexuan established the Yanhuang Academy to seek support for himself. A support that would allow him to establish a foothold in this feudal era of the Emperors, establish his family, and establish his life so that others would not easily touch him!
Only when the students of Yanhuang College became more and more promising, and when there were more and more promising students in the Academy, would his support become more and more reliable!
The reason why Confucius shone in the world and his name went down in history was not only because of his own greatness, but also because he had 3,000 students who spread his teachings and sent him to the altar in one fell swoop!
Li Zexuan knew that he couldn't be a saint like Confucius. He only wanted to seek a solid support in this feudal era. That was all!
"My husband, you have worked hard for this family!"
Han Yuxi caressed Li Zexuan's forehead with some heartache, then leaned on his shoulder and said softly.
"Hehe! I don't have to suffer! In this life, I have a wife who understands me and parents who love and protect me so much. I don't have to suffer! "
Li Zexuan caressed Han Yuxi's long hair and comforted her softly. After a while, he said, "Oh! Shiqing also wrote a letter to his mother. I have to get someone to send the letter to Chang 'an. My wife, you should also pack up. We will return to Lantian County in a while! "
"Mm, mm! Oh, right, my husband, it seems like we can't go back today! "
Han Yuxi nodded first, then shook her head and said.
Li Zexuan was suddenly puzzled and asked, "Why is that? Does my wife have something to do in Yunshan? "
Han Yuxi saw that Li Zexuan really couldn't remember what it was and could only helplessly say, "My husband, have you forgotten? Tomorrow is Pang Feiji's wedding. Pang Feiji has followed my husband all the way and has risked his life several times. Even if he didn't make any contributions, he has worked hard. Tomorrow is his wedding. Shouldn't my husband make a trip there? "
Li Zexuan opened his mouth and suddenly understood. Liu Feng had mentioned this to him before, but he had too many things to do on a daily basis and accidentally forgot about it. At this time, he smiled a little embarrassedly and said, "Yes, yes, yes! Ah! Look at my memory, I almost forgot about this! Thank you for reminding me! Then let's not go back to the county tonight. Let's go to the wedding banquet tomorrow! "
"Mm, mm!"
Han Yuxi smiled sweetly and nodded in agreement.
