Liu Zheng followed Jiang Xuan to a deep mountain on the outskirts of Liangzhou.
Today's Liangzhou is full of factories and workshops. Industry, as well as light industry, as well as handicrafts, have developed significantly. Therefore, there is no need to go to Yintan City for some things. There are also production bases near Liangzhou.
"Master!"
As soon as I arrived here, I saw Wei Tiezhu running over with joy. Today, Wei Tiezhu is the counselor of the entire Ministry of Works in Liangzhou. He is in charge of the entire Ministry of Works and has a high position of power. But he still plunged into the mountains, leading a group of craftsmen, busy with something.
"The iron pillar is getting stronger!"
Liu Zheng laughed.
Thinking of him and his father, when they first came to Liangzhou, it was Wei Tiezhu who led a group of people to build the county prince's mansion. Since then, he had his first follower.
Although Wei Tiezhu was born in a farm family, he has a strong learning ability and now knows all the big and small things about the Ministry of Works.
In Liangzhou, industrial development is a major theme set by Liu Zheng. So you must leave it to someone you can trust. Wei Tiezhu is the perfect choice. Even though he held an important position, he did not have the bad habits of other officials. When he saw Liu Zheng, he still had a simple and honest face, with dark skin and white teeth.
Well, he is still the same boy as before, without any change.
Liu Zheng chuckled and said, "Thank you for your hard work, Brother Wei."
Wei Tiezhu quickly shook his head.
Jiang Xuan laughed beside him and said, "You've worked so hard, why? Brother Wei just got married recently, so he just jumped into the mountains. That little wife must have some opinions!"
"real or fake?"
Liu Zheng was stunned for a moment, then looked overjoyed: "Which girl is it from?"
I went to Liangshan this time, and Wei Tiezhu actually got married? But think about it, his age is indeed about the same. Thinking of this, he still felt a little guilty. This was the brother he had grown up with. He was married and he didn't even know. He felt ashamed.
Wei Tiezhu glared at Jiang Xuan fiercely, then smiled innocently, with a hint of amusement, and said, "A girl from the Wang family."
"Liangzhou Wang family?"
Liu Zheng smiled and nodded: "It is considered a wealthy family, worthy of my brother Wei. I will have to prepare a big gift for my sister-in-law later!"
The three of them joked a bit.
At this time, we have arrived in the mountains.
At a glance, there are many stills hidden among them.
In the deep mountains, the smoke is lingering, which is the green smoke produced after the burning of the still.
Liu Zheng nodded and said, "Brothers must pay attention to safety."
When Jiang Xuan heard this, he shouted: "No, this green vitriol oil is so powerful. It burned through my gloves last time!"
When Liu Zheng and Wei Tiezhu heard this, they laughed.
That's right.
When Liu Zheng knew about the danger of blocking the ship, he asked Jiang Xuan to prepare here. What is green vitriol oil? It’s actually sulfuric acid!
in ancient times.
There have been methods of refining sulfuric acid for a long time, but at that time they were mostly used by warlocks to make alchemy. They used green vitriol to calcine it to produce green vitriol oil, which was sulfuric acid in the true sense!
We all know that strong acids can dissolve cement!
But Liu Zheng felt that sulfuric acid alone was not enough. He wants to prepare aqua regia!
Aqua regia is actually a mixture of sulfuric acid and nitric acid!
So, now that we have sulfuric acid, where does nitric acid come from? Of course it’s saltpeter! Saltpeter, also known as potassium nitrate, is calcined in a closed container to produce nitrogen dioxide, which dissolves in water and becomes nitric acid.
Then nitric acid and sulfuric acid combine to form extremely corrosive aqua regia.
This process is not very complicated, but containers have become a more difficult thing to solve. Fortunately, Liu Zheng had a glass container. He had to use an ordinary ceramic container, but he really didn't dare to put it in.
Liu Zheng looked at the bustling scene and asked with a smile: "How much have you accumulated?"
Wei Tiezhu said in a loud voice: "Young Master came back with the order, and we are rushing to make it. Now it is about two thousand kilograms!"
Liu Zheng was overjoyed: "Okay, that's enough!"
"Hahahaha, when will we go over and melt that cement block?"
Jiang Xuan gritted his teeth as he spoke. During this period, he was really troubled by those large pieces of cement.
Liu Zheng smiled: "Don't worry, let the bullets fly for a while..."
"ah?"
Liu Zheng smiled slightly.
Just as Qing Yangshuo said, Liangzhou has actually overcome the chaos that the ship jam first brought to Liangzhou. After all, it has been so long. There are no waterways, and there are still land routes. Even people can carry food here...
Now the ship jam is affecting only the Grand Canal and Yinzhou coins.
Liu Zheng doesn't mind, he will wait for more and more money to flow into Liangzhou and start another wave of harvest!
Having already arrived in this mountain, Liu Zheng was not in a hurry to go back.
This place has been built into a chemical factory in the mountains by Wei Tiezhu.
Suddenly he remembered that he had just promised Wei Tiezhu to give his wife a gift.
Liu Zheng suddenly had a whim.
According to his current status, it would be meaningless to give him some gold and silver jewelry...
What should I give as a gift?
He thought for a moment, and finally his eyes lit up.
Got it!
He turned back to Jiang Xuan and said, "Go and bring me some flat glass, tin foil, and mercury right away!"
Wei Tiezhu and Jiang Xuan looked at each other.
Is the young master going to tinker with something new again?
Thinking like this, the two of them were still very excited. I think back then... In fact, not long ago, Liu Zheng came out with a new invention in just a few days, and he suddenly developed the economy of Yinzhou, a barren land.
Now, with Liangzhou in hand, the power is overwhelming.
Liu Zheng's time to invent was gone.
This time Liu Zheng acted on a whim again, which naturally reminded the two of them of their green days.
"Okay, I'll get ready right away!"
Jiang Xuan galloped away on horseback.
Wei Tiezhu followed Liu Zheng curiously: "Master, what are you going to do this time?"
Liu Zheng chuckled: "How about something to please the girl? I will give Brother Wei a month's leave today, go back and spend time with my sister-in-law, and try to give Liu Zheng a nephew as soon as possible, okay?"
"oops……"
Wei Tiezhu's face turned red.
But he still followed Liu Zheng curiously.
Something to please girls?
Liu Zheng found a house built here and got into it.
There were some empty glass bottles in the room. Suddenly, Liu Zheng felt like he was in a chemistry class in his previous life. Chemistry, he never dared to slack off in the development of this aspect.
Before leaving, he had handed the periodic table of chemical elements to Mo Chen at Wangbei Academy.
It is estimated that there will be progress there soon.
soon.
Jiang Xuan found everything Liu Zheng needed.
Liu Zheng rolled up his sleeves and looked excited.
The two stood nearby, watching expectantly.
Wei Tiezhu looked at Liu Zheng who was very happy.
He laughed too.
He is still the same boy as before...
…
"boom!"
Looking towards the North Academy.
A small building collapsed again.
Why do you say it is again?
Because this is already the seventh time in these three days...
"Third Senior Brother!"
"Third Senior Brother, are you okay?"
"Third Senior Brother, how are you?"
A group of students searched out Mo Chen from the sawdust and rubble.
Mo Chen's face was black and blue, and his hair was half burned.
However, his eyes at this time were full of excitement.
"awesome!"
"X, is this chemistry?"
"Liu Zhizhou, you didn't lie to me, you didn't lie to me! Three acids and two alkali, three acids and two alkali, that's what it is!"
Then he stood up from the rubble, picked up a bunch of bottles and cans, and ran to the next small building.
Everyone had a dark look on their faces.
"No, pull him out quickly!"
"That's the building of our literature department!"
"quick!"
"Boom!"
