Take the mall to Datang

This was made by Li Chunfeng and others. Yuan Shan looked at it for a long time in the morning. In broad daylight, this thing can't pass through the clouds at all, but it has a higher magnification than ordinary telescopes, and the magnification effect is better.

"How does this thing look like a telescope?" He Tu looked at it and said.

"He Zhengjian knows about telescopes?" Yuan Shan asked.

"Your Majesty took a small one and asked the officials to find a way to imitate it." He Tuo said.

Yuan Shan felt that the amount of information was quite large when he heard it.

"It shouldn't be difficult to imitate a telescope with He Zhengjian's craftsmanship," Yuan Shan said.

"Yeah, I just copied one, because the cost of colored glass pieces is too high, so I canceled the plan to mass-produce them." He Tuo said.

Yuan Shan felt that He Tu was really honest, but it didn't matter. Didn't the development of utensils all start from imitation?

"He Zhengjian, what do you think of this circular monocular?" Yuan Shan asked.

"This object can see farther than ordinary telescopes. The glass installed inside is also very delicate and clear." He Tuo said.

"Well, it can see farther. In fact, this telescope is mainly used at night and after the lens is adjusted, it can see farther than it is now." Yuan Shan explained.

"Oh, you can see farther." He Tu looked curiously for a while.

"Master Hou is truly a genius for making such an exquisite telescope." He Tuo said.

"Where there are gods and people is applied scientific knowledge. Gewuxue, which is popular in Chang'an City, is a part of science. I recommend He Zhengjian to read it in his spare time." Yuan Shan said.

"It must be seen." He Tuo said.

"The three thousand guan allocated by the imperial court have arrived, and I will not bother you if you are a lower official." He Tuo left, and Yuan Shan sent it to the door.

He said in his heart that He Hu was quite anxious, and it would be great if his craftsmanship could be passed down.

Back in the yard, I started to play with the telescope again. In broad daylight, I can’t see anything. The light is too strong. With the current technology, the telescope can only magnify the object as much as possible. If you want to observe the stars, you can only look at the surface, unless you invent an optical telescope. You can see farther, and you can use radio telescopes if you want to observe the universe, but it's all nonsense for current technology.

Yuan Shan has already planned to mass-produce some large-scale telescopes, and then find a high mountain near Chang'an to place them on it for tourists to overlook the appearance of Chang'an. Of course, a fee is required.

Otherwise, he really doesn't know what other uses the telescope can have besides being used by the Beiya Imperial Army. In addition, Li Shimin's actions made him very unhappy. Only let Li Chunfeng look at the stars when he is free.

It is definitely a good thing to develop an activity for stargazing enthusiasts, so that people can have fun looking at the stars after dinner.

"Master Hou, Feng Zhidai is asking to see you." Caiyi came over and said.

"Well, ask someone to move this telescope back to the talent school for students to use to climb high and look far." Yuan Shan ordered.

Finally went to the reception room.

"Long time no see, Tianxi, how you've been doing recently." Yuan Shan came in to greet him.

"Thanks to Pushe, everything is fine. This time I came here about Lingnancao." Feng Zhidai said.

"What's wrong?" Yuan Shan asked.

"After my father collected and planted Lingnan grass around Lingnan, more and more people knew that Lingnan grass could be exchanged for money and began to plant separately. However, later curious people made their own claim to study the function of Lingnan grass. The thing used to repel mosquitoes was later lit and smoked by some people out of curiosity, and found that Lingnan grass had a refreshing effect, and then the Yue people fought for this thing, causing a great chaos in Lingnan, so my father was very distressed. It was originally used to exchange money for the development of Lingnan, but I didn't expect it to cause wars because of this thing, I don't know what good strategy Yuan Pushe has." Feng Zhidai asked.

"I've learned a lot after spending so long in the officialdom of the imperial court. I didn't come here to inquire about the method. I clearly thought that the Marquis already knew the function of Lingnan grass, so he came here to increase the purchase price." Yuan Shanxin said.

You are not stupid these days. There are not many Lingnan grasses. After several years of planting, the Feng family has the largest planting area of ​​Lingnan grasses, but the prices of these things are not very valuable. I found Lingnan grasses. After it has a refreshing effect, the price cannot be calculated according to ordinary caterpillar fungus, but according to the price of medicinal materials.

Yuan Shan originally didn't want these things to flow to the people, even if the supply was released, it wouldn't matter, the refreshing effect was obvious, especially for manual laborers who used Lingnan grass to be a little bit tired.

"Lingnan grass actually has a refreshing effect, but I'm ignorant, so I know that this thing can repel insects, so let's ship more of the next batch of Lingnan grass. When the time comes, I will find someone to study it. The purchase price is naturally not high. Luncao came to buy it, how do you feel about doubling the original value?" Yuan Shan said.

"I'm afraid it will be difficult to provide a large amount, because Lingnan grass is now planted in the whole of Lingnan. Even if the Feng family comes forward, it may be difficult to receive the price. With the influence of the Feng family in Lingnan, if it can be increased by five times, maybe the Feng family can still do it. Make a deal with the Yue people." Feng Zhidai said.

"Fifty Wen a catty, the cost is a bit high, so we should support the construction of Lingnan." Yuan Shan said.

"Then thank you Yuan Pu for shooting." Feng Zhidai said.

"The payment for the goods is still converted into cement and other materials and transported to Lingnan as usual." Feng Zhidai said.

"Nowadays, the transportation capacity is used to transport grain. It may be difficult to arrange delivery. If there is a large demand for cement in Lingnan, I can help the building materials chamber of commerce to directly build a cement kiln in Lingnan. The price of cement will be lower then." Yuan kindness.

"Materials such as cement are extremely heavy and difficult to transport. If this can be done, the Feng family will definitely not forget Yuan Pushe's great kindness." Feng Zhidai said.

"The development of Lingnan is related to the lives of the people. It would be great if we can take this opportunity to make them rich and avoid the suffering of war." Yuan Shanyu said earnestly.

Feng Zhidai saw that Yuan Shan really cared about the development of Lingnan, and he was very grateful.

Before he could say something grateful, Yuan Shan continued: "Lingnan is a good place. If it can be developed, it will be the number one place in the Tang Dynasty. The climate in Lingnan is mild, and it is suitable for fish, fruit, mulberry, and silkworm breeding. , Rice can be said to be a natural granary. The treasure ship built by Cangzhou Shipyard has been launched for trial voyage. At that time, a batch of materials will be transported to Lingnan for trading. At that time, I hope that Chief Feng can make preparations in advance. Lingnan invests in the construction of a wharf, and the labor force will be hired by Baiyue, provided there is no trouble."

Chapter 640 Lingnan Grass Export

Feng Zhidai was excited.

"Yuan Pushe don't worry, with Feng's family in Lingnan for a day, we can guarantee that there will be no problems with the construction project." Feng Zhidai said.

"I want to bring this good news to my father so that he can prepare early." Feng Zhidai continued.

The opening of sea routes is a major event. If sea ships can really go to the development of Lingnan, the development of Lingnan will no longer be a problem.

"Well, go back and get ready." Yuan Shan said.

Feng Zhidai knew that there was an opportunity for Lingnan. As soon as the big ship arrived, Lingnan's special products would go north, and as long as the trade was opened, Lingnan would not be a poor place, and Yuan Shan seemed to see the value of Lingnan.

Feng Zhidai left happily, and Yuan Shan began to plan the matter of Lingnan grass. The role of Lingnan grass has been known by many people, and it cannot be covered. In this case, why not open a Lingnan grass processing factory? , Through some technical treatment, the harm can also be reduced to the nearest minimum.

Yuan Shan didn't feel any guilt. After all, he was the one who first proposed this Lingnan grass, otherwise tobacco would not have been used so early.

Shaking his head and feeling a sigh, obviously Yuan Shan is not a hypocritical person.

Fifty Wen per catty, the price is a bit more expensive, but compared to the profit after processing, it is unimaginable. At that time, the lowest price will start from fifty Wen a tael.

Thinking of this, he planned to ask someone to prepare a car and went directly to Yuanjia Papermaking Workshop.

In the car, Yuanshan didn't take his time to exchange a book about papermaking from the system, and put the book in his arms after checking it.

When entering the paper mill, there is a strange smell coming out of the nostrils. People who work here wear thick masks to work, otherwise the vomited pulp can suffocate people to death.

The guy in charge of the paper-making workshop is Zhu Wenfu, who was originally the first batch of servants recruited by the Yuanjia Manor. Later, he temporarily worked with several servants to prepare for the construction of the paper-making workshop. The few people at the beginning have now developed into a group of more than a hundred people working on papermaking. .

Not only papermaking but also printing, movable type printing is going on in the printing room, and the printing is Datang Tomorrow Tabloid, and everyone is busy.

"Wen Fu, is the paper workshop so busy every day?" Yuan Shan asked.

Although the paper-making workshop is his property, he doesn't come here very often, so the paper-making workshop has always handled various things by itself. It is natural not to know the situation, but he is not afraid of problems in the workshop with the accounts in hand.

"Yes, since Lord Hou opened the talent training school, the demand for paper has greatly increased. The paper workshop is limited in scale and can only work overtime." Zhu Wenfu said.
