Otaku Engineer in Great Tang Dynasty

"Master, why are you here~?"

In the Qiquge workshop, Fubo saw Li Zexuan and hurriedly greeted him.

Li Zexuan stopped, but his eyes scanned in the courtyard, while watching, he replied:

"Fu Bo, I heard that the vanadium ore from the Shu area had been shipped back, so I came to have a look! Where are they? How many are there in total?"

Fubo said with a smile: "Master, the ore has been transported to the steel mill. The old man knows that the master values ​​this type of ore, but he dare not pile it up!"

Li Zexuan smiled, just as he was about to speak, another person entered the workshop.

"The vanadium mine is here, where is it... Shan Chang, are you here too?"

The person here is Wang Ji.

Vanadium is a necessary catalyst for the large-scale mass production of concentrated sulfuric acid. Not only Li Zexuan is concerned, but Wang Ji has been waiting for the vanadium mine in Shuzhong to be shipped back quickly.

Li Zexuan smiled and nodded, and said, "Well! Mr. Wang, are you so fast?"

Wang Jile said: "Hey! As the head of the chemistry department, of course, the old man has the responsibility to help the college develop new chemical materials. This vanadium ore old man has been looking forward to it for a long time!"

"Master, the guards who transported the mines this time were all Qiang people from the Shu area. They also brought two letters, saying that they were given to you by Mr. Ke!"

At this time, Uncle Fu took out two painted letters from his arms, handed them to Li Zexuan, and said.

"Mr. Xiao Ke?"

Hearing this name, Li Zexuan was a little dazed subconsciously. After a moment, he recovered and couldn't help but happily said, "It should be Ke Shiqing, right? Ouch, it seems that this young man got mixed up in the Qiang tribe. Not bad~! They are all honored as Mr.!"

Wang Ji stroked his beard and smiled proudly: "Our students at Yanhuang Academy will be like stars and moons wherever they go. The old man Ke Shiqing has some impressions. He is indeed a good, diligent and studious child~!"

This old guy now looks like some old gentlemen in modern times. When he learned that his students are promising, he was very contented in his heart, but he was still quite reserved and restrained in his mouth and face. Li Zexuan couldn't help but want to laugh.

"Haha! Let's go! Mr. Wang, let's take a look at the fineness of these vanadium ore together?"

Li Zexuan saw that Fu Bo was secretly facing Wang Ji who was "smelly fart" and hurriedly pulled Wang Ji toward the steel mill.

"Ah~! With so many ores, can you extract a lot of vanadium?"

Walking into the yard of the steelmaking plant, I saw a large pile of light gray ore piled under a cloth shed. At a glance, it could be thousands of catties. Wang Ji's eyes widened and he couldn't bear it. Exclaimed.

Li Zexuan walked up to the front, picked out a piece from the pile of ore at random, took it to the front, looked at it carefully for a moment, and smiled:

"Yeah! The fineness is very good! Mr. Wang, this pile of vanadium-titanium magnetite can produce at least 300 catties of vanadium. This amount of vanadium is enough to cope with the consumption of sulfuric acid produced by the workshop! Let the craftsmen in the workshop remodel the boiler and set up a small-scale vanadium smelting workshop, and then another sulfuric acid workshop to produce a batch of concentrated sulfuric acid as soon as possible. I have great use!

Wang Ji replied excitedly: "Yes! Shan Chang!"

Even if Li Zexuan didn't say it, he would take the initiative to ask for it. After all, he finally got so much vanadium-titanium magnetite. If he couldn't refine it by himself, he would have hairy in his heart!

"Oh! By the way! Shan Chang, the "Chemistry" textbook says that this sulfuric acid is highly corrosive and can react with iron to form copper sulfate and hydrogen. Then what should we use to store concentrated sulfuric acid in the future?"

Wang Ji paused for a moment, then said suddenly.

Li Zexuan thought for a while, then smiled and replied: "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. However, the contact between concentrated sulfuric acid and iron does not Will or rarely react.

Because of the high purity of concentrated sulfuric acid, sulfuric acid exists as a covalent compound instead of an ionic compound. When the purity is high, it ionizes very few hydrogen ions, almost none, so it will not corrode ironware, but will A passivation reaction occurs with iron, so that a dense oxide film is formed on the surface of the iron. This dense oxide film prevents the 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 under 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 the concentrated sulfuric acid The safety of storage requires the use of horizontal storage tanks and a leak-proof wall around the storage tanks.

Sulfuric acid storage rooms must be strictly prohibited from fireworks, because there will be a small amount of dilute acid on the surface of the concentrated sulfuric acid liquid that reacts with iron to produce hydrogen. Hydrogen will explode when exposed to fire. In terms of safety, Mr. Tarzan! I don't want any safety incidents in our workshop! "

In the end, Li Zexuan's face must be solemn.

Even in modern times, chemical plants are also the most prone to safety accidents. Either the leakage of toxic chemical products or the explosion caused by flammable substances, no matter which one, will bring significant impact to the surrounding people. hurt!

It is precisely because of this that Li Zexuan has repeatedly exhorted Wang Ji so solemnly!

Wang Ji also understands the stakes. He solemnly said: "The chief of the mountain can rest assured that the old man will put safety first, and regularly train the craftsmen on safe production, and combine their monthly wages with the production safety. The implementation situation is linked, so that everyone will strictly abide by the regulations of safe production!"

Li Zexuan's eyes lit up and he nodded and said, "Well! Mr. Wang, you have a good idea. When you turn back, you will discuss with Fu Bo how to implement this wage system as soon as possible. Craftsmen who comply with the regulations will pay more and violate the safety production regulations. Just deduct the money and let all the craftsmen in the workshop take it seriously!"

"Mountain leader, no problem! The old man knows the importance!"

Wang Ji nodded and responded.

……………………………

After instructing Wang Ji to pay attention to safe production, Li Zexuan asked Wang Ji to produce a batch of concentrated sulfuric acid as soon as possible, because he was going to be a battery!

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 described as one thing with multiple uses and two birds with one stone!

After leaving the workshop and returning to the other hospital, Li Zexuan took out the letter that Fu Bo gave him. On the envelope, one reads "Shan Chang's kiss," and the other said "Mother, please." Li Zexuan opened it. The letter Feng Ke Shiqing wrote to himself began to read carefully.

"Since leaving Yunshan, it has been almost a month in a blink of an eye. Shiqing misses the people and things in the academy very much, but Shiqing is even more grateful to Shanchang for the opportunity to benefit the people of his hometown this time. Now, he is from Guanzhong to Shu. Roads are being built;

The imperial court also sent a large number of officials with a lot of money to support the people's livelihood construction in Shu;

A group of merchants from Chang'an City also opened shops in Chengdu Prefecture. They brought many new things that local people had never seen before. The business in Shuzhong was very prosperous;

The mining of vanadium-titanium magnetite has allowed the local Qiang people to work in the mines to earn money, but within half a month, the wages received by each miner almost equals the previous three or four months of income. !

Following your instructions from the head of the mountain, Shiqing adheres to the principle of safety first, preferring to mine the vanadium mine more slowly, but also to ensure the safety of the miners, so no one has been injured or killed since the vein mining!

Oh, by the way, "Datang Daily" has also opened an office in Shuzhong. Nowadays, people in Shuzhong are getting used to reading newspapers every morning! Students saw in the newspaper yesterday that Shan Chang had invented a new type of waterwheel and made the drawings public. Shi Qing is proud of being a student of Shan Chang!

In addition, His Royal Highness Shu asked to set up the Yanhuang Bank Branch in Shuzhong. With the help of Gao Changshi, the people and merchants in Shuzhong have slowly begun to accept the new currency of Tang Yuan and use copper money. The number of people is getting fewer and fewer!

With the help of the Sanbao brothers, the students brought Quyuanli, "Datang Dictionary", bicycles, coal stoves, and honeycomb coals to the middle of Shu. With the support of Gao Changshi, they helped to develop people’s wisdom and prosperity. Things, promote business!

Today's Shuzhong is undergoing earth-shaking changes. How fortunate for the students to witness the growing prosperity of their hometown and the richer lives of the villagers! The student once remembered that Shan Chang said before: \'You have to feel shallow on paper, you must do it by yourself\'. The students realized the true meaning of this sentence in the process of leading the people in their hometown to get rich!

Some things seem simple, but when they are really done, they often encounter a lot of difficulties. Fortunately, those students who are in difficulties have heard them. Now the students have become Mr. Xiao Ke in the eyes of the people of Zhangzhou!

The mountain leader can rest assured that the students will win without arrogance and defeat without discouragement. Haosheng will lead the people in Shu to become rich, and will never shame the mountain leader or discredit Yanhuang Academy!

Student Ke Shiqing bows down and wishes Shan Chang everything goes well and healthy! "

"Sang Gong, what are you looking at? So happy?"

Just after reading the letter, Li Zexuan was about to sigh, when Han Yuxi happened to come over and asked with a soft smile.

"Haha! It's nothing! It's a letter from a college student to my husband!"

Li Zexuan smiled, drew his wife to his side, and smiled.

"Students' letters? Aren't all Xianggong's students in the college? Why do I need to write to you?"

Han Yuxi frowned the pretty willow leaf eyebrows and said in doubt.

Li Zexuan smiled and asked, "Lady, still remember the student named Ke Shiqing who invited Ying to go to Shuzhong earlier?"

Han Yuxi condensed her eyebrows for a while, and she said, "Oh! Concubine remembered that, earlier his mother came to Yunshan to send you a letter to Xianggong!"

"Yeah! That's him! This kid is now doing good work in Shuzhong. He is a teacher for his husband. I am very pleased to see it~!"

Li Zexuan handed the letter to Han Yuxi, and then smiled.

"That's it! Why do I laugh so happily!"

Han Yuxi took the letter paper, swept it aside, and said with joy: "The Xianggong is benefiting the people of Lantian County, but Ke Shiqing is benefiting the people in his hometown. This student is very much like you! The students of Yanhuang Academy will be able to be like Ke Shiqing in the future. In the same way, use what you have learned to benefit one party. At that time, Xiang Gongke will truly be full of peaches and plums, and his fame will endure through the ages~!"

Li Zexuan heard this, his heart inevitably stirred. He patted his wife on the shoulder and sighed: "So, Yanhuang Academy is the Tang Dynasty, our family's greatest wealth and reliance! Rather than delve into the art of intrigue, get into the court. , It’s better to start school and build a government and teach what you have learned to thousands of disciples. He will treat me all over the world. Even if you are the prime minister and emperor, you should respect me three points!"

These words are the truth in his heart!

At the beginning, Yanhuang Academy and Communication Engineering were founded to benefit the people of the world and seek a little welfare for the working people of this era. At the same time, Li Zexuan founded Yanhuang Academy to seek a support for himself, one who can settle down in this era of feudal emperor. Stand on your feet, settle down, and let others dare not easily move their own reliance!

Only when the students of Yanhuang Academy become more and more promising, and when there are more and more promising students, his reliance will become stronger!

In addition to his own greatness, the reason why Sage Kong is so shining and famous is that he has three thousand disciples spreading his doctrine and sending it to the altar in one fell swoop!

Li Zexuan knew he couldn't be a saint like Confucius~www.readwn.com~ He just wanted to get a solid support in this feudal age, nothing more!

"Miangong, you have worked hard for this family~!"

Han Yuxi stroked Li Zexuan's forehead with some distress, then nestled on the latter's shoulder and said softly.

"Hehe! I am not bitter for my husband! I know my wife in this life, and there is such a love and care for my parents, not for my husband!"

Li Zexuan stroked Han Yuxi's long hair and comforted him softly. After a while, he said, "Oh! Shiqing wrote a letter to his mother to send the letter to Chang'an for her husband. , You also pack up, we will return to Lantian County in a while!"

"Hmm~! Oh, by the way, Xiang Gong, we don’t seem to be able to go back today!"

Han Yuxi nodded first, then shook his head, and said.

Li Zexuan suddenly wondered: "Why is this? Does the lady still have something to do in Yunshan?"

Seeing that Li Zexuan really couldn’t remember what happened, Han Yuxi had no choice but to say, “Did you forget the father? Tomorrow will be Pang Feiji’s wedding. Marriage, both fair and reasonable should go there, right?"

Li Zexuan opened his mouth, and it suddenly dawned on him that Liu Feng had mentioned this to him before, but he had too many things in his daily life and he forgot about it accidentally. At this time, he smiled embarrassedly: "Yes. Hey! Look at the memory of my husband, I almost forgot about it! Thanks to the lady for reminding you! Then we won't go back to the county town tonight, and we will have a wedding tomorrow together~!"

"Hmm!"

Han Yuxi smiled sweetly and nodded in response.
