Lishan has many secret casting recipes. Since handing over papermaking to the Central Government, Lishan's industry has been streamlined and focused on casting.

There is still a factory in Lishan, but it will not be expanded.

Many manufacturing equipment originally located in Lishan were transported to Chang'an City, and Cen Wenwen and Wei Zheng came to inspect them in person.

The instruments sent by Lishan were huge and made of iron.

Niu Chuang explained casting related matters to the people from the Ministry of Works. Seeing these craftsmen from the Ministry of Works discussing the principles, he yelled and cursed and stamped his feet in anger.

The people from the Ministry of Industry couldn't help but ask for advice. Finally, Niu Chuang took the Lishan people away, and both parties broke up unhappy.

Only a group of craftsmen from the Ministry of Works were left talking among themselves.

Chao Zhong wanted to make his own paper, and Lishan also gave him the secret recipe for paper recycling.

I didn't expect that it would be so unpleasant just after it started.

Cen Wenwen took the drawing and said, "Fortunately, Lishan has written it in detail, so it can work."

Wei Zhengdao: "The craftsmen in the Ministry of Industry are all top-notch in craftsmanship. There has been a lot of talk about Lishan from both the government and the public. The people in the Ministry of Industry have always been very high-spirited."

Cen Wenwen frowned and said, "This is not a good thing."

Wei Zheng stroked his beard and said: "Many people have suffered losses in Lishan with this kind of mentality."

Hearing the meaning of these words, Cen Wenwen was surprised and said: "Mr. Zheng speaks highly of Lishan."

Wei Zheng nodded and said: "At least Zhang Yang has been doing what he thinks should be done."

Cen Wenwen sighed: "Your Majesty should let him enter Lingyan Pavilion."

Those who enter Lingyan Pavilion are those who are absolutely loyal to His Majesty. If Zhang Yang wants to enter Lingyan Pavilion, he must devote himself wholeheartedly to Tian Khan.

This is Zhang Yang...

Cen Wenwen shook his head and smiled, "I don't know what Zhang Yang is about."

The court was busy, the machine of the Tang Dynasty was running, and each department was performing its duties.

Today a memorial was sent to the court. The memorial was sent from Tongguan. Lishan wanted to buy a river beach in Tongguan.

Li Shimin looked at the memorial and asked, "What is the use of that river beach?"

Changsun Wuji said: "The exposed river beach will become a new road, but if the water level of the river bed rises again, this river beach will be useless and will be submerged in the water."

After thinking for a moment, Changsun Wuji said: "Your Majesty, unless Zhang Yang is sure that the water level in the river bed will not rise again, but will continue to fall year after year, this river beach will be of use."

"Zhang Yang is sure, can you be sure?"

After hearing His Majesty's question, Changsun Wuji replied: "The Yellow River rises and falls erratically, and I dare not conclude that there will be another road to the north of Tongguan."

Li Shimin said in a deep voice: "Do you have an offer for Lishan?"

"Back to Your Majesty, Lishan has not made an offer yet. He just asked the Prince of Jiangxia to inquire. Lishan intends to buy it."

If the water level of the Yellow River rises again, Lishan will lose everything he bought on this river beach.

Li Shimin wanted to see Lishan lose all his money and didn't want to see Lishan make money, so he asked, "How much land does he want to buy?"

"Back to Your Majesty, the memorial sent from Tongguan said that there are 1,000 acres of river beach. This is all."

"Okay." Li Shimin said solemnly: "One thousand acres of river beach, twenty thousand guan. If Lishan dares to pay this money, I will sell it to him."

"Here."

Changsun Wuji asked the palace to draw up the documents and hurriedly sent them to Lishan.

Unexpectedly, Lishan sent silver coins the next day, and what they delivered were all silver cakes. After weighing, they even amounted to more than 20,000 coins.

This inevitably made everyone in the court wonder how rich Lishan was. He took out 20,000 yuan without batting an eye.

Just to buy an exposed piece of river beach?

Li Shimin had a vague feeling that he had been tricked. The reason for this feeling was that Lishan paid so readily.

Without even haggling, does he still think it's a good deal?

Li Shimin looked at the pile of silver cakes in front of him, twenty thousand coins.

This is not a small sum, I even reached out to pick up a piece of silver cake and weighed it in my hand to confirm that it was genuine.

No matter what, if you sell a river beach in Tongguan, you can earn 20,000 yuan. Of course, the emperor is willing to do this kind of business.

Originally, the river beach was not included in the field register of Tongguan. It was a river bed exposed due to the drop in the water level of the Yellow River, which was equivalent to an extra piece of land created out of thin air.

I kept telling myself in my heart, I made a profit! I made a profit! I made a profit!

Li Shimin felt much better now.

In Lishan, Zhang Yang looked at the documents sent from the court with excitement in his eyes, "Twenty thousand guan, this is a great deal."

Li Yue was mending the children's clothes. There was still a lot of gold in the Lishan warehouse, and silver cakes were piled up like a wall.

The family does not need much money in daily life, and the money used for circulation in the village is only copper coins.

She whispered: "Anyway, there are so many silver cakes in the warehouse that I can hardly put them down, so it doesn't hurt to take some out."

Zhang Yang plans to build a commodity distribution center in Tongguan. From a geographical point of view, it is crucial to the economy, water transportation, and river management.

I pay attention to the changes in water and soil in Guanzhong every year and every month, and it was an unexpected surprise to find this river beach.

If you capture this river beach, you also capture the ancient Weihan Road, and its status is no less than that of Hangu Pass.

In the factory, Lishan spent two months building a new steam engine.

This steam engine looks much smaller, only the size of a haystack.

It was built based on the proportions of my brother-in-law's model train.

It doesn't make that much noise when it's running.

Several villagers were tightening the screws on the joints of the steam engine.

In this way, a brand-new steam engine appeared in front of people.

It has a chimney and a water tank as high as a person.

The previous steam engines were very rough, but now this one is obviously much more refined. It is rectangular and completely black.

There are a lot of yellow dots, which are the joints fixed by copper screws.

Put the coal stone into the furnace inside it and wait for it to burn.

Li Tai attached the magnet to the iron barrel and then placed the copper coils. The coils were very dense and were wound around the iron pestle.

Several guards carefully connected it to the steam engine.

These magnets are strong magnets excavated from the Western Regions.

After a while, the steam engine started to sound, and the iron barrel made of magnets began to rotate. Li Tai watched the changes in the coil closely.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Yan Liben said: "It was originally intended to be a locomotive."

Li Tai looked at the new steam engine that had just been built and said: "Let it be borrowed for use first, and then it will be installed on the front of the car."

It was the summer harvest season in August, and there were not many people in the factory. The villagers had all gone to collect grain.

Yan Liben said: "If Lishan only sells steam locomotives in the future, it will be able to make a lot of money, even more than Lishan could make before."

After living in Lishan for a long time, Li Tai no longer cares about money.

Having been in business with his brother-in-law for so long, he didn't know how much money he had. Every year, Lishan's profit sharing was delivered to his house by the truckload.

My brother-in-law holds a big share of the Lishan business. God knows how rich he is now.

This steam engine is very efficient and has a high speed.

Yan Liben kept recording the operating efficiency of each stage of the steam engine. A whistle sounded and the iron cylinder rotated faster.

Li Tai stared at the coil inside, but there was no change except for rotation.

This lasted for half an hour, and Li Tai stared at it for half an hour.

As he spoke, he picked up another piece of iron, and with self-doubt in his heart, he threw the iron piece into the iron cylinder.

When the iron material touches the copper wire, an electric light flashes.

"Um?"

Li Tai's eyes widened and he threw it at it again. Just like the last time, electricity exploded.

"Your Highness King Wei! Is that electricity?"

Li Tai thought, "It's different from the thunder seen in the sky, it can only be said to be a little bit different."

After that, he walked to the back of the steam engine and opened the air valve to release the air. The air pressure inside the steam engine was released from the air port.

It finally stopped spinning.

Li Tai took down the iron bucket, took the booklet his brother-in-law had given him, pulled out two copper wires, and said, "Catch a pig."

"Your Highness, King Wei, wants to eat pork?"

"Stop talking nonsense and go quickly!"
