Of course, Ang Lee had a telescope that could see further. Moreover, before going up the mountain, he asked the soldiers of the Yulin Royal Guards to help carry it up. At that time, Yan Ruyu also asked about it, but Ang Lee changed the topic and evaded the question.
"Come on, carry it up."
Ang Lee ordered several soldiers of the Yulin Royal Guards to carry up the telescope with a fixed tripod and set it up in the pavilion.
"Husband, this is a telescope that can see further. Why do you put it on a tripod?"
Yan Ruyu looked at the more luxurious telescope in surprise and asked with a frown.
Ang Lee briefly explained to her the knowledge of optics and magnification, such as reflection and refraction, the principle of magnification, and how the image would shake if the magnification was too high, such as using a tripod to fix it, and so on.
But Yan Ruyu's brain capacity was very limited. She couldn't understand a word at all. She looked at Ang Lee with admiration and felt that her husband was so powerful and knowledgeable.
Ang Lee didn't expect Yan Ruyu to understand. He directly set up the telescope with a magnification of 50, aimed the lens at the woman in the distance, and saw that the item in the woman's basket was an egg.
"Madam, it's an egg."
Ang Lee let Yan Ruyu see it by herself and taught Yan Ruyu how to use the fixed telescope.
After Grass painstakingly climbed to the top of the mountain, in order to compensate, Ang Lee let her and Yan Ruyu enjoy the scenery in the distance.
Sure enough, when Grass Grass saw that the telescope was so awesome that she could see the scenery in the distance, her original complaint disappeared in an instant. She happily took the telescope and enjoyed the scenery everywhere, like a cheerful bird.
Li An had long had enough of playing with the binoculars. Moreover, as a person who had lived two lives, his mental age was much older than his actual age. It was enough for him to let Yan Ruyu and Cao 'er have fun. He was already very comfortable standing next to them.
"Colonel Duan, this telescope is for you. Maybe you will need it in the future."
Ang Lee handed the binoculars to Duan Xiushi.
Although Duan Xiushi and a dozen Yulin guards had been following Ang Lee, they didn't follow him when he entered a safe place. For example, after entering the palace, Duan Xiushi would lead guards to guard outside Ang Lee's mansion, the processing plant, and other places to prevent danger from entering.
Therefore, when the telescope was developed, Duan Xiushi and the others did not know about its existence. Although they had seen Ang Lee using the telescope to observe something, they did not know that it was a telescope. After all, Ang Lee had invented too many gadgets.
Since Duan Xiushi has seen Ang Lee use binoculars, she naturally knows how to use them. She took the binoculars and looked into the distance. Suddenly, she was shocked. The distant scenery seemed to be in front of her.
"No wonder Assistant Minister Li often uses this telescope to look into the distance these days. It turns out that it can zoom in so much as if it is in front of you."
Duan Xiushi said in shock. Then, she said excitedly, "Assistant Minister Li, this telescope can see the situation in the distance. If it is given to the scouts in the army, they will definitely be able to find the enemy earlier. It will be very beneficial to our army. Why don't you give it to the imperial court?"
Sure enough, after Duan Xiushi, who was born in the army, got the telescope, the first thing she thought of was to use it to spy on the enemy, so as to win the initiative for the army of the Tang dynasty.
"Of course, I have to give it to the imperial court. Haven't I been improving it all the time? Only after many experiments can I make a telescope that is hard and not easy to break. Only then can I give it to the imperial court! In a few days, it will be time for the morning court. I plan to bring these telescopes to the imperial court and give them to His Majesty during the morning court so that His Majesty and the ministers can see them. Then, I will promote them. "
Ang Lee had thought about this problem for a long time. However, he had to make a sturdy military model so that it could be better used in the military. In addition, the first batch of telescopes he made were relatively rough, especially the high-power telescopes with a magnification of 50. They could not be used normally at all. Now, after a series of improvements, their performance had been greatly improved, and their stability and firmness had been greatly increased. It was time to give them to the imperial court. However, Ang Lee did not want to give them to Li Longji in private. Instead, he wanted to surprise the ministers of the Tang dynasty during the morning court and increase his prestige again.
"That's great. With these telescopes, the army of the Tang dynasty can be the first to discover the enemy in the future and make tactical adjustments. Thank you, Assistant Minister Li, for your gift. I accept it."
Duan Xiushi was very excited and happily accepted Ang Lee's gift. Anyway, Ang Lee could make telescopes, so it was not a big deal for him to accept this gift. Moreover, he really liked telescopes and had a hunch that he would definitely need them in the future.
In the small pavilion on the top of the mountain, Yan Ruyu and Grass were looking around with the telescopes. After playing for more than two hours, they did not feel tired at all. Moreover, the more they played, the more skillful and flexible they became. Soon, they became experts in using the telescopes. Their movements of holding the telescopes became more and more professional.
Before dusk, Ang Lee walked down the mountain with Yan Ruyu and Grass, who had not played enough, and returned to the mansion in the city by carriage. In the carriage, Yan Ruyu made a fuss and asked Ang Lee to give her the telescopes she had played with. Even Grass joined in the fun and asked Ang Lee for a hand-held telescope with a magnification of 10 magnification.
Ang Lee had made a lot of telescopes this time, including a set for himself and his wife, Yan Ruyu. Therefore, he very generously agreed to Yan Ruyu's request. Of course, he also agreed to Grass's request. However, he warned them not to take it out casually, otherwise it might cause trouble.
Yan Ruyu and Cao 'er were both timid girls. When they heard Li An's warning, they were so scared that they repeatedly nodded their heads and promised that they wouldn't casually take out the binoculars. At most, they would stay on the third floor of the residence and look at the scenery outside.
In the morning court a few days later, Ang Lee asked Zhao Liu to lead a group of male servants to take the telescopes to the Daming Palace. This time, his biggest goal was to present the telescopes to the imperial court of the Tang dynasty, so as to serve the military and astronomy of the Tang dynasty.
Outside the Great Ming Palace, Li An had Zhao Liu and the male servants stay behind as usual. They were waiting for the Emperor to summon them so that they could bring the binoculars in. However, after he gave the order, a young eunuch walked over and respectfully said, "His Majesty has decreed that in the future, if Assistant Minister Li has something good to offer to the court, you don't need to wait outside the palace gates. You can directly wait outside the Political Announcement Hall.
Ang Lee was stunned for a moment, then smiled and waved his hand. He led a carriage of telescopes to the Political Announcement Hall and asked Zhao Liu and the others to stay.
"Assistant Minister Li, what good things do you have to present to His Majesty this time?"
"The last two times, it was black gunpowder and movable type printing. This time, it must be something good that will shock us!"
"Assistant Minister Li, can you tell us first so that we can be mentally prepared?"
Several ministers whose official positions were slightly lower than Ang Lee's came over and inquired about the situation from Ang Lee.
Ang Lee pursed his lips and did not answer. For ministers whose official positions were lower than his, he did not need to answer all their questions. It was necessary to maintain some official prestige.
"Assistant Minister Li, what good things are in this carriage? Can't you tell us a little bit?"
An old minister whose official position was higher than Ang Lee's was a little shaky when he walked, but he could not get rid of his curiosity.
Ang Lee naturally could not be too rude to such a respected old minister, so he said, "Clairvoyance."
"Clairvoyance?"
This old minister and many other ministers were suddenly very surprised. What did Ang Lee mean when he said clairvoyance? Clairvoyance could see things a thousand miles away, but how could there be such a thing in the world?
A few of the ministers wanted to continue asking, but Li An was younger and walked faster. In a few steps, he had shaken them all off.
Li Longji was more proactive this time and came earlier. Perhaps it was because Yang Yuhuan was not feeling well, so he came earlier.
After the court, the ministers first reported the various progress of the spring plowing. After all, it was spring plowing now, and nothing was more important than spring plowing. This year's spring plowing went more smoothly than previous years.
Ang Lee was the greatest contributor. First of all, Ang Lee invented gunpowder, which greatly increased the mining speed of iron ore. As a result, the price of pig iron fell by a lot, and the price of iron farming tools naturally fell as well. This way, many people who could not afford farming tools in the past could use them, and the efficiency of farming greatly increased.
In addition, Ang Lee also improved the water wheel, which saved a lot of effort in irrigating the fields. These two things together made this year's spring plowing much smoother than previous years. It was estimated that the spring plowing would end three days earlier, so the people could free up their hands to participate in the corvee work of the court.
The smooth progress of the spring plowing made Li Longji very happy. He praised all the ministers who were in charge of the spring plowing. Of course, he did not forget Ang Lee's contributions. At the end, he singled out Ang Lee for praise.
The officials of the Imperial College also took the opportunity to list out the benefits of Ang Lee's pinyin. They also said that the movable type printing technology could be popularized soon.
A good morning court had become a meeting to praise himself, which made Ang Lee feel a little embarrassed. However, these were all facts. If it were not for his contributions, the Tang dynasty would not have achieved what it had today.
"Everyone, Assistant Minister Li has brought a cart full of things into the palace."
Just as the ministers were discussing the movable type printing technology and pinyin, a young eunuch told Li Longji that Ang Lee had brought a cart full of things.
"Assistant Minister Li, what good things did you come up with this time? A cart full of things?"
Li Longji did not wait for Ang Lee to take the initiative to speak and directly asked.
"Your Majesty, this is a telescope that I developed a few days ago. It can also be called clairvoyance. It can see things hundreds of miles away, or even thousands of miles away."
Ang Lee calmly reported word by word.
"Telescope, clairvoyance, you can really make such things!"
"It can see things hundreds of miles away, or even thousands of miles away. It's amazing."
"Assistant Minister Li is getting more and more capable. He can even invent clairvoyance. It's incredible."
All the ministers were suddenly in an uproar. They were all shocked and expectant, and couldn't wait to experience the mystery of the telescope immediately.
After Li Longji heard this, he was naturally very interested. Being able to see things from a hundred or a thousand miles away was simply too miraculous. It was simply unimaginable.
"Assistant Minister Li, why don't you give me the telescope?"
Seeing Li Longji's eyes, the young eunuch hurriedly said in a loud voice.
"Your Majesty, the space in the hall is too small and dark to use the telescope. Your Majesty, please move out of the hall. In this way, you can see more clearly."
Ang Lee cupped his fists and suggested.
Of course, Li Longji wouldn't refuse. He immediately stood up and strode out of the Political Announcement Hall. All the ministers curiously followed behind, ready to see the power of the telescope.
This time, in order to let all the ministers experience it, Ang Lee exaggeratedly brought fifty monoculars with a magnification of ten to fifty. In addition, there were five fixed monoculars with a magnification of ten to fifty. In other words, the magnification of the telescope could be adjusted.
Under Ang Lee's orders, Zhao Liu, with the help of a group of young eunuchs, pulled up all fifty-five telescopes and had Zhao Liu set up the fifty magnification telescopes at once, and the ten magnification telescopes were stacked together.
Ang Lee picked up a ten magnification telescope and explained to Li Longji and the ministers how to use it. He personally demonstrated it, and then handed the telescope in his hand to Li Longji. At the same time, he had Zhao Liu hand the remaining forty-nine telescopes to the ministers.
Although the number of ministers was far more than fifty, the number was absolutely enough for them to experience it.
"Your Majesty, these small telescopes have a magnification of ten. They can shorten the distance by ten times. Things that are a thousand steps away look like they are a hundred steps away."
Ang Lee carefully explained.
"Sure enough, it's ten times closer."
Li Longji's expression was very excited. Moreover, this expression appeared after trying to hide it. It could be seen how excited he was in his heart. The expressions of the ministers were not much different. They all had a happy expression and praised Ang Lee's ability to invent this magical thing.
Of course, there were also many ministers who immediately thought of the huge role of the telescope. Those who had led troops in wars thought of using it for military purposes. Those who liked astronomy thought of using it to observe the stars in the sky.
"Assistant Minister Li, these telescopes set up here must be able to see farther, right?"
Li Longji was not stupid. Of course, he could guess that the telescopes set up on the ground were of a higher magnification. The other ministers had also thought of it.
"Your Majesty, these are telescopes with a magnification of ten to fifty magnification. The magnification can be adjusted. It can be zoomed in by ten to fifty times and see farther."
Ang Lee introduced clearly and explained how to operate this relatively complicated high-magnification telescope. He adjusted the magnification from ten to fifty magnification so that Li Longji could observe the changes in objects.
Because the five fixed telescopes were relatively far apart, some ministers who knew how to use them began to take turns to experience the pleasure of the fifty magnification telescope, and all of them were amazed.
