Open an aircraft carrier to fight against Japan

Upon hearing this, Lin Yuan was surprised and said, "What the hell?"

Cheng Jiuzhen said: "After turning over that hillside, there is a large open space with no grass growing on it. If you turn over a layer of soil, there will be a piece of reddish stone underneath. Those things are so evil. Once they stick to the body, they will be sticky. The place will be sore, and it will take a few days to heal."

Lin Yuan suddenly thought of something, he said, "Let's go and have a look together."

Cheng Jiuzhen hurriedly stopped her, saying: "You can't go, the ancestors passed down a word that you absolutely can't go to that place."

The woman was crying and kneeling on the ground, Cheng Jiuzhen sighed and said, "Go back, it's fate to die in this place!"

Lin Yuan said, "Master Jiu, that place is probably not a ghost land, but a treasure land."

Cheng Jiuzhen frowned, and asked, "My respected guest, what did you say?"

Lin Yuan smiled and said, "Master Jiu, let me go and have a look."

Cheng Jiuzhen gritted her teeth and said, "Then I will risk my life to accompany the gentleman, let's go together."

Lin Yuan smiled and said, "Get two towels soaked in water."

Soon the towels were brought, Lin Yuan and Cheng Jiuzhen climbed over the hillside, Lin Yuan couldn't help sighing: "It's so windy."

It turns out that the mountains around this open space happen to be wide on the outside and narrow on the inside. When the wind blows in from outside the mountains, it is equivalent to being accelerated, so the wind here is very strong.

Lin Yuan walked to the open space, took a shovel, and shoveled it on the ground, turning over the soil on the ground surface, revealing a layer of reddish and yellowish stone. Lin Yuan almost jumped up excitedly when he saw these things, these are sodium saltpeter ah!

These things are excellent materials for the production of potassium nitrate. Potassium nitrate and iron sulfide are burned together in the air to produce sulfuric acid. What are the basic raw materials for inorganic chemicals?Three acids and two bases!With sulfuric acid, nitric acid can be obtained by reacting with potassium nitrate, and hydrochloric acid can be obtained by mixing sulfuric acid with sodium chloride and heating, so that there will be three acids, and the inorganic chemical industry has taken an important step!

It stands to reason that sodium nitrate is the easiest to be hydrolyzed and lost, but on this island, there is such a large piece of soda nitrate mine, I have to lament the ingenious workmanship of nature!

Lin Yuan explained the reason to Cheng Jiuzhen. Although Cheng Jiuzhen didn't know the purpose of these stones, she became happy when she saw Lin Yuan was so happy.

The two searched around, but didn't find the child. At this time, the sky was slightly bright, and the two felt that this place didn't look like someone had been there before. The child might not have come here.

The two returned to the original place, and the crowd was still waiting for them. When the woman saw them, she said apologetically, "I'm really sorry, my child didn't go to the ghost land, he just ran out to play, and I will definitely go back." Teach him a lesson."

Cheng Jiuzhen smiled and said, "It's okay, we found a treasure this time!"

Everyone was overjoyed, Lin Yuan didn't care about the celebration, and hurried back to the Beijing warship station. When Su Zhengming heard the news, he patted his thigh and smiled, "Great!"

But Su Zhengming's complexion quickly sank, and he said worriedly: "Our chemical industry needs equipment! These equipment need a lot of steel, but we don't even have a little steel now, and we urgently need machines like lathes Processing equipment."

At this moment, someone came to report that the British cargo ship was coming with coal and iron ore, and now it was at the port. The British who came had a quarrel with Mr. Liu, and people on both sides were about to fight!

Upon hearing this, Lin Yuan quickly followed the man to the port.As soon as Lin Yuan arrived, he saw a group of stevedores with shovels standing in the open space, surrounded by a pile of coal, standing there at a loss.Liu Jinqiu sat cross-legged on the pile of coal, panting for breath. Opposite him stood a blushing British man with a thick neck. It was obvious that the two had just had a quarrel.

When Lin Yuan heard Liu Jinqiu's Chinese-English swearing method, he couldn't help but burst into laughter. He helped Liu Jinqiu up from the ground, and said with a smile: "Old Liu, why did these British guys provoke you?"

Unexpectedly, the Englishman said angrily: "Who do you call an Englishman!"

Lin Yuan did not expect that the Englishman could understand Chinese, so he quickly said: "Sorry, no offense! (Sorry, no offense intended)"

Liu Jinqiu said angrily: "Just call you British guys, are you bullying us? We have never seen bituminous coal! Use a boatload of lignite to fool us."

In the process of smelting iron and steel, coke is needed as fuel, and there is very little natural coke, which needs to be coked from bituminous coal.Coal can be divided into many types according to the degree of coalification. Lignite is a kind of coal with a relatively low degree of coalification. This kind of coal cannot be coked to obtain coke.

The price of lignite is indeed much cheaper than bituminous coal. The British supplier thought that no one in Ryukyu understood the difference between bituminous coal and lignite, so he secretly replaced bituminous coal with lignite. Unexpectedly, he met Liu Jinqiu, a master of the metallurgical industry. .

The Englishman knew he was in the wrong, but he still insisted: "Ours is obviously bituminous coal, the best bituminous coal!"

Liu Jinqiu laughed and said, "Did you skip classes all the time when you were in school? Bituminous coal has a metallic luster. Look at the coal in your boat, that piece has such a luster!"

Liu Jinqiu had taught in a university, and knew that skipping classes was a common occurrence for college students. When he was in a hurry, he never thought that there was no such word in the 19th century.The Englishman also half understood, and wanted to argue, Liu Jinqiu threw the piece of coal back to the coal pile, and said: "How did you pull the coal in your boat? How can you pull it back? I am now Just look at your iron ore, I guess the grade of your iron ore is not enough!"

The British commanded the workers to unload a batch of iron ore and pile them on the open space. There were three iron ore ships in total. After unloading, Liu Jinqiu looked at the red stones and said to Lin Yuan: "The British on the iron ore No tricks, these are hematite, the main component is ferric oxide, so it will appear red or light red, so it is also called red ore. The iron content of this iron ore is usually around 70.00% in theory , although the iron content is not as high as that of magnetite (the main component is ferric oxide), but the grade meets the requirements of our contract.”

The Englishman smiled and said, "Is there any problem with this batch of iron ore, can we sign the contract?"

Lin Yuan smiled and said, "We still have to go to the boat to see." The Englishman was displeased and muttered something in English, but neither Lin Yuan nor Liu Jinqiu understood, knowing that he must be speaking in English scold them.

Lin Yuan and Liu Jinqiu boarded the ship and checked cabin by cabin. The first two ships were fine, but when they got to the third ship, Liu Jinqiu caught fire when he saw the iron ore, and said to Lin Yuan: " How dare you use pyrite ore to fool us!"

Then, Liu Jinqiu picked up a shovel and turned over the ore, and saw that there were yellow-green stones under the red stones. Liu Jinqiu was so angry that his face turned red, and he said angrily: "Do you know? I hate cheating. When I was in college, there was an undergraduate student who copied a thesis during his graduation project. I refused to let him graduate! How dare these foreign devils fool me!

Lin Yuan was really afraid that he would hit the British profiteer's head with a shovel, so he quickly took the shovel and said with a smile: "Mr. Liu, calm down, be careful not to burn yourself out of anger."

Lin Yuan heard the word "pyrite", and his heart moved immediately. He whispered a few words to Mr. Liu, then pulled the Englishman aside, and said with a smile, "Why? The price of pyrite is cheaper than that of hematite. Lower?"

The British knew that the trick had been seen through, so they had to say: "Now the British are crazy about building warships, and the demand for steel is huge. Now the price of iron ore has doubled by half."

Lin Yuan smiled and said, "We can sign the contract, but you have to give us some benefits."

Looking at the confused expression of the British, Lin Yuan said: "These iron ores were originally worth 25 pounds, and now we pay you 20 pounds. You must not suffer, because these iron ores are worth at most 18 pounds, but we The contract still says 20 pounds, so [-] pounds will fall into my pocket. Do you understand? But we can't accept the coal."

The British nodded and said yes, so the two sides settled down like this.When he was leaving, Liu Jinqiu said with a smile: "You really have a way. This saved us [-] pounds, and also got the pyrite that we urgently need to develop the chemical industry."

While they were talking and laughing, a new crisis was approaching the precarious Qing Dynasty in the north.
