Datang: An eight-year-old master of the bar, he gave everyone a blow at the beginning

Chapter 365 Yuchihuan has successfully made the telescope
Wei Zheng, Fang Xuanling and the others watched the globe and left Zhongshu Province satisfied.

Cheng Yaojin and Li Jingru received the amnesty, and immediately returned to the Ministry of War with the globe.

When the globe arrived at the Ministry of War, it was immediately surrounded by the generals and nobles of the Tang Dynasty.

The minister of the Ministry of War was full of praise for the globe sent by Yuchihuan. In the future, Tang Jun would not be afraid to get lost in the desert and grassland with the globe.

In the afternoon of the same day, according to Li Er's will, Xu Jingzong, the supervisor of the Shaofu, sent the soap profits belonging to Yuchihuan to Changle Palace!
Princess Changshan now has more than 30 gold and silver stored in Changle Palace, making her the richest man in the Tang Dynasty!
But these belonged to Yuchihuan, and Princess Changshan just kept them for him.

In the future, when Princess Changshan marries Yuchihuan, the gold and silver will be sent to Yuchi's house in the name of dowry.

In the afternoon, Yu Chihuan went to Changle Palace to find Princess Changshan, and then gave Princess Changshan a globe!
Princess Changshan was overjoyed when she got another globe, and she was very grateful to Yuchihuan.

"Chang Shan, I gave you this globe, don't just give it away!"

Before Yuchihuan left Changle Palace, he seriously reminded Princess Changshan.

Princess Changshan pursed her lips and said: "Brother Huan, I will listen to you from now on and will not give the globe to my father and queen!"

Yu Chihuan nodded in satisfaction and said, "Chang Shan, as long as you know how to do it!"

"Brother Huan, it's getting late, why don't you have dinner with me?"

Princess Changshan then invited Yuchihuan to have dinner before leaving.

Yu Chihuan shook his head and smiled wryly: "Chang Shan, I still have things to do, let's forget about dinner!"

"Brother Huan, if that's the case, then I won't keep you!"

Princess Changshan nodded in answer to Yuchihuan.

Yu Chihuan then exchanged greetings with Princess Changshan before leaving Changle Palace.

Princess Changshan stared at Yuchi Huan's hurried figure, thinking wildly: "Brother Huan, is it because I gave the globe to the emperor today, so you are angry with me?"

……

Tai Chi Palace, three provinces and six divisions!

In the evening, Yu Chihuan returned home after finishing his official duties at Zhongshu Province.

"Young Prime Minister Yuchi, please stay!"

As a result, as soon as Yu Chihuan walked out of the gate of Zhongshu Province, he was immediately stopped by Yan Lide, the minister of the Ministry of Industry, who walked out next door!
Yuchi Huan asked curiously: "Master Yan, do you have anything to do with me?"

Yan Lide nodded and said: "Young Prime Minister Yuchi, I have seen the globe you gave to the Ministry of War. This object can be used for positioning. It is not only suitable for marching and fighting, but also suitable for caravans to walk in the deserts of the Western Regions. Can you send the globe design to me?" To the Ministry of Works?"

Yu Chihuan suddenly realized: "Master Yan, does your Ministry of Industry want to imitate the globe?"

Yan Lide smiled embarrassedly.

"Little Chancellor Yuchi is worthy of his sharp eyes, he can see through the thoughts of the officials at a glance!"

Yuchi Huan sighed and said, "Master Yan, I don't have the blueprint for the globe. I'm afraid you will be disappointed!"

The globe has a positioning function, which is something produced by the system, and of course it cannot be judged by common sense!

Yan Lide wants to imitate a globe with a positioning system, that is a fantasy!
Yuchihuan couldn't even do it by himself!
When Yan Lide heard what Yuchi Huan said, he was surprised and said, "Prime Minister Yuchi, can't even you make a globe?"

Yu Chihuan nodded and said yes: "Master Yan, I can't make a globe that can be positioned, but the globe used for the map can still be imitated!"

"Ah... Unexpectedly, there are things in this world that Young Chancellor Yuchi can't do hahaha!"

Yan Lide laughed heartily as if he had discovered a new continent!

In Yan Lide's eyes, Yuchihuan was omnipotent.

But the myth of Yuchihuan has been shattered today.

Yu Chihuan didn't have the same knowledge as Yan Lide, he patted Yan Lide on the shoulder and said, "Master Yan, you can copy the map on the globe for the Ministry of War to use!"

"Subordinate to obey!"

Yan Lide answered Yuchihuan with his arms raised.

"Master Yan, can you arrange some craftsmen who know how to make colored glaze for me tomorrow?"

Yu Chihuan suddenly remembered the astronomical telescope promised to Princess Changshan today!
Pure glass is absolutely indispensable in the manufacture of astronomical telescopes!

The raw material of concave lens and convex lens is glass.

The colored glaze of the Tang Dynasty is actually the glass of later generations.

At present, Liuli workshop is a government-run industry, which belongs to the monopoly industry of the Ministry of Industry.

Yan Lide, as Minister of the Ministry of Industry, of course knows the situation of the Datang Liuli Workshop!
"Okay, sir, let's do it now!"

Yan Lide agreed to Yuchihuan without hesitation.

"Master Yan, if there is nothing wrong, I will be on duty!"

After Yu Chihuan finished speaking, he left Zhongshu Province.

"Young Prime Minister Yuchi, go slowly!"

Yan Lide stood at the gate of Zhongshu Province and watched Yuchihuan leave.

After seeing off Yuchi Huan, Yan Lide immediately went to the Ministry of War to copy the world map on the globe!

When Li Jing, Minister of the Ministry of War, learned that Yan Lide copied the globe map for use by the Ministry of War, he was surprised and delighted, and agreed to Yan Lide's request on the spot.

Yan Lide came from the Yan family, a family of painters. He and his younger brother Yan Liben were both well-known Confucian scholars in the Tang Dynasty!

Yan Liben is currently the general supervisor of the Ministry of Industry. When he learned that Yan Lide was drawing maps in the Ministry of Industry, he immediately ran over to help.

An hour later, one hundred flawless world maps were drawn!
Yan Lide took a world map to the Ministry of Industry, leaving the other world maps for the Ministry of War.

The painters of the Ministry of Industry received the world map brought back by Yan Lide, and they devoted themselves to painting overnight.

That night, Yu Chihuan learned that Yan Lide used a globe to make a world map, and he was full of praise for Yan Lide's work efficiency.

……

Chang'an City, Suzaku Avenue!

Early the next morning, Yu Chihuan went to the Ministry of Industry to ask Yan Lide for a craftsman who was good at making colored glaze!

Sure enough, Yan Lide did not disappoint Yuchihuan, he gave ten artisans who were proficient in colored glaze to Yuchihuan that morning!

Yuchi Huan then directed craftsmen to make transparent glass in the glaze workshop of the Ministry of Industry!

The transparency of glass is closely related to the raw material.

Therefore, Yuchihuan directly uses crystal clear crystal stones to make glass.

At noon that day, Yuchihuan finally got three pieces of transparent glass the size of a palm.

Yuchihuan then ordered craftsmen to polish the glass into concave and convex lenses!

In the afternoon, the craftsmen of Liuli Workshop finally ground out the 16-yuan concave lens and convex lens!

Having obtained the raw materials for making astronomical telescopes, Yuchihuan immediately ordered craftsmen from the Ministry of Industry to manufacture astronomical telescopes!

In less than a stick of incense, the astronomical telescope Yuchihuan needed was successfully manufactured!
So Yu Chihuan held the astronomical telescope to the sun, and the sunlight gathered through the glass to form a glare, which proved that the astronomical telescope was successful.

Yuchihuan was overjoyed, so he tried the astronomical telescope himself, and the result really allowed him to see many stars hundreds of millions of miles away.

Next, Yuchihuan used the extra concave and convex lenses to make a telescope!
In the evening, all three telescopes and three astronomical telescopes were successfully produced!
