"Master, why are you here~?"
In the Qiquge Workshop, Uncle Fu saw Li Zexuan and hurriedly came forward and said.
Li Zexuan stopped and scanned the courtyard with his eyes. While looking, he replied:
"Uncle Fu, I heard that the vanadium ore from Shu has been shipped back, so I came over to take a look! Where are they? How many are there in total?"
Uncle Fu said with a smile: "Master, the ore has been transported to the steel mill. I know that the master values this kind of ore, but I don't dare to pile it outside!"
Li Zexuan smiled and was about to speak when another person came into the workshop.
"The vanadium mine is here, where is it... Chief, are you here too?"
The person who came was none other than Wang Ji.
Vanadium is a necessary catalyst for the large-scale production of concentrated sulfuric acid. Not only Li Zexuan is concerned, but Wang Ji has also been waiting for the vanadium ore in Sichuan to be shipped back as soon as possible.
Li Zexuan smiled and nodded, saying: "Yes! Mr. Wang, you are always very fast, aren't you?"
Wang Jile said: "Hey! As the team leader of the Chemistry Department, I have the responsibility to help the academy develop new chemical raw materials. I have been looking forward to this vanadium ore for a long time!"
"Master, the guards who transported the ore this time are all Qiang people from Shu. They also brought two letters, saying that their Mr. Xiao Ke gave them to you!"
At this time, Uncle Fu took out two lacquered letters from his arms, handed them to Li Zexuan, and said.
"Mr. Xiao Ke?"
Hearing this title, Li Zexuan was a little confused subconsciously. After being stunned for a moment, he came back to his senses and couldn't help but said happily: "It should be Ke Shiqing, right? Oops, it seems that this young man is living well in the Qiang tribe. Not bad~! Everyone calls him sir!"
Wang Ji stroked his beard and said with a proud smile: "We, the students of Yanhuang Academy, will become like stars and the moon wherever we go. I have some impression of Ke Shiqing. He is indeed a good boy who is diligent and studious~!"
The way this old guy looks now is exactly like the way some old gentlemen in modern times look like they are very proud of themselves when they learn that their students are promising, but they are still quite reserved and restrained on their mouths and faces. Li Zexuan couldn't help but want to laugh.
"Haha! Let's go! Mr. Wang, let's take a look at the quality of this batch of vanadium ore?"
Li Zexuan saw that Uncle Fu was secretly pouting at the "stinky" Wang Ji, and quickly pulled Wang Ji towards the steelmaking plant.
"Hey~! With so much ore, a lot of vanadium can be extracted, right?"
Walking into the yard of the steelmaking plant, he saw a pile of large and small light gray ores piled under a cloth shed. At a cursory glance, it weighed at least a thousand kilograms. Wang Ji's eyes widened and he couldn't bear it. Zhu exclaimed.
Li Zexuan walked closer, picked out a piece from the ore pile at random, brought it to him, looked at it carefully for a moment, and said with a smile:
"Well! The quality is very good! Mr. Wang, this pile of vanadium-titanium magnetite can produce at least three hundred kilograms of vanadium. This much vanadium is completely enough to meet the consumption of the workshop to produce sulfuric acid! You have been working harder recently. Let the craftsmen in the workshop renovate the boiler, build a small-scale vanadium refining workshop, and then build a sulfuric acid-making workshop to produce a batch of concentrated sulfuric acid as soon as possible. I will be of great use!"
Wang Ji responded excitedly: "Yes! Chief of the mountain!"
Even if Li Zexuan didn't say anything, he would take the initiative to ask for help. After all, he finally got so much vanadium-titanium magnetite. If he couldn't refine it himself, he would be very angry!
"Oh! By the way! Chief Shan, the Chemistry textbook says that sulfuric acid is highly corrosive and can react with iron to produce copper sulfate and hydrogen. So what should we use to store concentrated sulfuric acid in the future?"
Wang Ji paused for a moment and suddenly said.
Li Zexuan thought for a while and replied with a smile: "Mr. Wang, dilute sulfuric acid can dissolve iron and release hydrogen. The reaction principle is that the freely moving hydrogen ions in dilute sulfuric acid react with iron. But when concentrated sulfuric acid comes into contact with iron, it does not Little or no reaction occurs.
Because the purity of concentrated sulfuric acid is very high, sulfuric acid exists in the form of covalent compounds, not ionic compounds. When the purity is high, it dissociates very few hydrogen ions, almost none, so it will not corrode iron, but will A passivation reaction occurs with iron, causing a dense oxide film to form on the surface of the iron. This oxide film is very dense and prevents concentrated sulfuric acid from entering the iron and continuing to react.
However, although concentrated sulfuric acid can be stored in carbon steel, the condition is that it is best to store it at normal temperature and pressure, so that the corrosion rate of carbon steel is the lowest, because hot concentrated sulfuric acid will also react with iron. In order to ensure that concentrated sulfuric acid For storage safety, it is necessary to use horizontal storage tanks and build leak-proof walls around the tanks.
Fireworks must be strictly prohibited in the storage room of sulfuric acid, because a small amount of dilute acid will react with iron on the surface of the concentrated sulfuric acid liquid to produce hydrogen. The hydrogen will explode when exposed to fire. In terms of safety, Mr. Wang, you must be cautious and cautious. Safety production is more important than Tarzan! I don’t want any safety incidents in our workshop! "
At the end of the sentence, Li Zexuan's face must be solemn.
Even in modern times, chemical plants are the most likely places for safety accidents. Either the leakage of toxic chemical products or the explosion caused by flammable substances. No matter which one it is, it will bring significant consequences to the surrounding people. harm!
It is precisely because of this that Li Zexuan warned Wang Ji so solemnly and repeatedly!
Wang Ji also understood the stakes. He solemnly handed over his hands and said: "Don't worry, Mr. Shan, I will put safety first. I will regularly train the craftsmen on production safety, and combine their monthly wages with the regulations on production safety." The implementation will be linked, so that everyone will strictly abide by the regulations on safe production!"
Li Zexuan's eyes lit up and he nodded: "Yes! Mr. Wang, you have a good idea. Later, you can discuss with Uncle Fu how to implement this wage system as soon as possible. Craftsmen who abide by the regulations will be paid more. Those who violate the safety production regulations Just deduct the money and make all the craftsmen in the workshop pay attention to it!"
"Captain, no problem! I understand the importance!"
Wang Ji nodded and responded.
………………………
After asking Wang Ji to pay attention to production safety, Li Zexuan asked Wang Ji to produce a batch of concentrated sulfuric acid as soon as possible, because he was going to make batteries next!
In addition, vanadium, the catalyst used in the production of sulfuric acid, can also be used as a catalyst for cracking petroleum in the future. It can be said that it has multiple uses and kills two birds with one stone!
After leaving the workshop and returning to the other courtyard, Li Zexuan took out the letter that Uncle Fu had given him. On one of the envelopes, it was written "My dear mother" and on the other envelope, "My dear mother". Li Zexuan opened the envelope. Feng Ke Shiqing began to read the letter he wrote to himself carefully.
"It has been nearly a month since he left Yunshan. Shiqing misses the people and things in the academy very much, but Shiqing is even more grateful to the mountain chief for this opportunity to benefit the people in his hometown. Now, from Guanzhong to Shu roads are being built;
The imperial court also dispatched a large number of officials with a large amount of money to support the construction of people's livelihood in Shu;
A group of merchants from Chang'an City also opened shops in Chengdu. They brought many new gadgets that the local people had never seen before. Business in Shu was booming;
The mining of vanadium-titanium magnetite allows everyone in the local Qiang people to work in the mines to earn money. In just half a month, the wages received by each miner are almost equal to the income of the previous three or four months. !
Following your instructions, Chief Shan, Shiqing adheres to the principle of safety first and prefers to mine the vanadium mine more slowly to ensure the safety of the miners. Therefore, there has not been a single casualty since the mine was mined!
Oh, by the way, "Datang Daily" has also opened an office in Sichuan. Now the people in Sichuan have become accustomed to reading the newspaper every morning! Students read in the newspaper yesterday that Shan Chang invented a new type of waterwheel and made the drawings public to the world. Shiqing is proud to be a student of Shan Chang!
In addition, His Royal Highness the King of Shu established the Yanhuang Bank branch in the middle of Shu. With the promotion of Gao Changshi, the people and merchants in the middle of Shu have slowly begun to accept the new currency of Tang Yuan and use copper coins. There are fewer and fewer people!
With the help of the Sanbao brothers, the students brought all the things that benefit the people, such as Quyuan plow, "Datang Dictionary", bicycles, coal stoves, and honeycomb briquettes, to Sichuan. With the support of Gao Changshi, they opened up the people's wisdom and promoted agriculture. To promote business!
Today's Shuzhong is undergoing earth-shaking changes. How lucky the students are to be able to witness the increasing prosperity of their hometown and the increasingly affluent lives of their fellow villagers! The students once remembered that the mountain chief once said: "What you see on paper will only make you realize it, but you must practice it to know it." The students only realized the true meaning of this sentence in the process of leading the people in their hometown to become rich!
Some things look simple, but in practice, you often encounter a lot of difficulties. Fortunately, the students who had difficulties have heard about it, and now the students have become Mr. Xiao Ke in the eyes of the people of Yizhou!
Don’t worry, the Mountain Chief. The students will not be arrogant in victory or discouraged in defeat. They will lead the people in Shuzhong to get rich. They will never embarrass the Mountain Chief or discredit the Yanhuang Academy!
Student Ke Shiqing pays his respects and wishes Mr. Shan everything goes well and good health! "
"Ms. sir, what are you looking at? Are you so happy?"
Li Zexuan had just finished reading the letter and was about to sigh a few words. At this time, Han Yuxi happened to come over and asked with a soft smile.
"Haha! It's nothing! It's a letter written by an academy student to my husband!"
Li Zexuan smiled, hugged his wife to his side, and said with a smile.
"Letter from a student? Aren't my husband's students all in the academy? Why do I still need to write to you?"
Han Yuxi wrinkled her beautiful eyebrows and said doubtfully.
Li Zexuan smiled and asked: "Madam, do you still remember the student named Ke Shiqing who volunteered to go to Shuzhong?"
Han Yuxi frowned and thought for a while, then said with a smile: "Oh! I remember, his mother came to Yunshan to deliver a message to you!"
"Yeah! That's him! This kid is doing very well in Shu. My husband, who is a teacher, is very pleased to see it~!"
Li Zexuan handed the letter to Han Yuxi and smiled.
"That's it! Why is my husband 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 in his hometown. This student is very much like you! Yanhuang Academy produces talents. If all the students in the academy in the future can be like Ke Shiqing In the same way, if you use what you have learned to benefit a country, then your husband will truly have peaches and plums all over the world and his reputation will last forever~!"
When Li Zexuan heard this, his heart was unavoidably agitated. He patted his wife on the shoulder and sighed: "So, Yanhuang Academy is the Tang Dynasty and our family's greatest wealth and support! Instead of studying the art of intrigue, hanging out in the court , it is better to open a school and build a mansion, and pass on what you have learned to thousands of disciples. In the future, I will be all over the world, even if you are the prime minister or the emperor, you should respect me three points!"
These words are true from the bottom of his heart!
The Yanhuang Academy and Communication Engineering were originally founded to benefit the people of the world and seek some benefits for the working people of this era. But at the same time, when Li Zexuan founded the Yanhuang Academy, he was also looking for a support for himself, someone who could settle down in this feudal imperial era. Establish a foothold, settle down, and let others dare not touch your reliance easily!
Only when the students of Yanhuang Academy become more and more promising, and when there are more and more promising academy students, will his reliance become more reliable!
The reason why Saint Kong is so glorious and famous throughout the ages, in addition to his own greatness, is that he has three thousand disciples who spread his teachings and put him on the altar in one fell swoop!
Li Zexuan knew that he could not be a saint like Confucius. He just wanted to find a solid support in this feudal era, nothing more!
"Ms. sir, you have worked hard for this family~!"
Han Yuxi stroked Li Zexuan's forehead with some distress, then leaned on the latter's shoulder and whispered softly.
"Haha! It's not hard to be my husband! In this life, I have a wife who knows me and understands me, and I have parents who love and protect me so much. It's not hard to be my husband!"
Li Zexuan stroked Han Yuxi's long hair and comforted him softly. After a moment, he said: "Oh! Shiqing also wrote a letter to his mother. My husband has to have the letter sent to Chang'an. Madam , you should also pack up, we will return to Lantian County in a while!"
"Hmm~! Oh, by the way, sir, it seems we can't go back today!"
Han Yuxi nodded first, then shook her head and said.
Li Zexuan suddenly asked in confusion: "Why is this? Does the lady still have something to do in Yunshan?"
Han Yuxi saw that Li Zexuan really couldn't remember what happened, so she had no choice but to say: "Have you forgotten, my husband? Tomorrow is Pang Feiji's wedding. Pang Feiji has followed his husband all the way, through life and death several times. Even if he has no credit, he still has hard work. He will get married tomorrow." You should go there for marriage, love and justice, right?"
Li Zexuan opened his mouth and suddenly realized that Liu Feng had mentioned this to him before, but he had too many things to do on weekdays and accidentally forgot about it. At this time, he smiled sheepishly and said: "Yes, yes, yes." ! Hey! Look at my husband’s memory, I almost forgot about this! Thanks to you for reminding me, madam! Then we won’t go back to the county town tonight, and we’ll have a wedding banquet together tomorrow~!”
"Uh-huh!"
Han Yuxi smiled sweetly and nodded in response.
