Of course, Li An has a telescope that can see farther, and before going up the mountain, he asked the soldiers of the Yulin Army to help carry it up, Yan Ruyu also asked at that time, but Li An changed the topic and prevaricated. Pen "Fun" Pavilion www.biquge.info

"Someone, carry it up."

Li An ordered several soldiers of the Yulin Army to carry up the telescope with a fixed tripod and put it in the pavilion.

"Husband, this is a telescope that can see farther, why do you put it on a tripod?"

Yan Ruyu looked at this more luxurious telescope in surprise and asked with a frown.

Ang Lee briefly explained to him the relevant knowledge of optics and magnification, such as reflection and refraction, the principle of magnification, and the magnification that too high will cause the image to shake, such as fixing with the help of a tripod and so on.

But Yan Ruyu's brain capacity is really very limited, she just can't understand a word at all, and looks at Li An with very admiring eyes, feeling that her husband is so powerful and knowledgeable.

Li Ang didn't expect Yan Ruyu to understand, so he directly set up a telescope with a fifty magnification, pointed the camera at the woman in the distance, and saw that the items in the woman's basket were eggs.

"Ma'am, it's an egg."

Ang Lee asked Yan Ruyu to see for herself and taught Yan Ruyu how to use a fixed telescope.

After Cao'er worked hard to climb to the top of the mountain, Li Ang made up for it and let her and Yan Ruyu enjoy the scenery in the distance.

Sure enough, when Cao'er saw that the telescope was so awesome and could see the scenery so far away, the original complaint disappeared in an instant, and happily took the telescope everywhere to enjoy the scenery, like a cheerful bird.

Li Ang has long had enough of playing with the telescope, and besides, he is a human being in two lives, and his mental age is much older than the actual one, so just let Yan Ruyu and Cao'er have a good time, and he is already very comfortable standing next to him.

"Captain Duan, this telescope has been given to you, maybe, you will be able to use it in the future."

Li An handed the telescope in his hand to Duan Xiushi.

Although Duan Xiushi and more than a dozen Yulin Army guards have been following him, they do not follow Li An when he enters a safe position, such as after entering the palace, in Li An's mansion, processing plant, etc., Duan Xiushi will lead the guards to guard outside the door and prevent danger from entering.

Therefore, in the days when the telescope was developed, Duan Xiushi and others did not know the existence of the telescope, although they had also seen what Li Ang was observing with the telescope, but they did not know that it was a telescope, after all, there were too many gadgets invented by Li An.

Since Duan Xiushi had seen Ang Lee use the telescope, he naturally knew how to use it, so he took the telescope and looked into the distance at will, and was immediately stunned, the distant scenery seemed to be right in front of him.

"It's no wonder that Li Shilang has often looked into the distance with this thing these days, and it turns out that he can bring the scenery so closer, just like in front of him."

Duan Xiushi said in shock, and then said excitedly: "Li Shilang, this telescope can see the situation in a distant position, if it is equipped with scouts in the army, it will definitely be able to detect the enemy situation earlier, which is greatly beneficial to our army, why not give it to the imperial court?" ”

Sure enough, Duan Xiushi, who was born in a soldier, after having a telescope, the first thing that came to mind was to use it to reconnoiter the enemy's situation, so as to gain the initiative for the Tang army.

"Of course it's going to be dedicated to the imperial court, isn't this official always improving? Only after many experiments can a sturdy and indestructible telescope be presented to the imperial court! In a few days, it will be time for the early dynasty, and I plan to bring these telescopes into the court during the early dynasty, and present them to Your Majesty, so that Your Majesty and the ministers can see them, and then promote them. ”

Li An has already considered this problem, but it is necessary to create a sturdy military type, in order to be better used in the military, in addition, the first batch of telescopes made are relatively rough, especially the high-power telescope with a rate of fifty magnification, which cannot be used normally at all, and now after a series of improvements, the performance and greatly, the stability and solidity have also been greatly increased, it is time to dedicate it to the imperial court, however, Li An does not want to give Li Longji a sullen private dedication, but to give the Tang Dynasty ministers a surprise in the early dynasty, And again increase their own prestige.

"It's really good, with this telescope, in the future, my Tang army will be the first to discover the enemy and make tactical adjustments, thank you Li Shilang for the gift, and accept it."

Duan Xiushi seemed very excited, and happily accepted the gift given to him by Li An, anyway, Li An will produce telescopes, and he accepted this gift, which is nothing to Li An, and he really likes telescopes very much, and has a hunch that he will definitely use them in the future.

In the small pavilion on the top of the mountain, Yan Ruyu and Cao'er, holding the telescope to look east and west, tossing for more than an hour, they didn't feel tired, and the two of them became more and more skilled and flexible the more they played, and soon became experts in using telescopes.

Before the evening, Li An took Yan Ruyu and Cao'er, who had not played enough, walked down the hill, and returned to the mansion in the city in a carriage.

Li An made a lot of telescopes in this batch, of course, including a set for himself and his wife Yan Ruyu, so he agreed to Yan Ruyu's request very generously, of course, he also agreed to Cao'er, but he warned them not to take them out to play casually, otherwise it might cause trouble.

Yan Ruyu and Cao'er are both timid women, and after listening to Li An's warning, they nodded in fright, and promised that they would not take out the binoculars casually, at most on the three-story building of the mansion, and look at the scenery outside the mansion.

A few days later, in the early dynasty, Li An asked Zhao Liu to lead a group of male servants to transport a cart of telescopes to the direction of Daming Palace.

Outside the gate of Daming Palace, Li An asked Zhao Liu and the male servants to stay as usual, so as to wait for the emperor to summon him, and then transport the binoculars in, but when he gave the order, a little eunuch came over and said respectfully: "Your Majesty has a will, in the future, if Li Shilang has good things to offer to the court, he doesn't have to wait outside the palace gate, just go directly to the Xuanzheng Palace and wait." ”

Li An was stunned for a moment when he heard this, then smiled slightly, stretched out his hand, and led a cart of binoculars to the outside of the Xuanzheng Palace, and asked Zhao Liu and the others to stay.

"Li Shilang, what good things do you want to offer to Your Majesty this time?"

"The last two times it was black powder and movable type printing, this time it must be a good thing that shocked me again!"

"Li Shilang, can you reveal it first, let me wait for a mental preparation."

Several ministers with slightly lower official positions than Li An leaned over and asked Li An about the situation.

Li An pursed his lips and did not answer, for ministers with lower official positions than himself, he did not need to answer all questions, it was still necessary to maintain a little official authority.

"Li Shilang, what kind of good thing is this whole car, can't you reveal a little?"

An old minister with a higher official rank than Li An walked a little trembling, but he couldn't change his curiosity.

For this kind of virtuous and respected minister, Li An is naturally not too unreasonable, so he said: "Claireye." ”

"Clairvoyance?"

This old minister and many ministers were all surprised, what did Li An mean when he said the three words clairvoyance? Can't clairvoyance be able to see things thousands of miles away, but how can there be such things in the world?

Several ministers wanted to continue to ask, but Li An was relatively young and walked faster, so he threw them all away in three or two steps.

Li Longji was more active this time and came earlier, maybe it was because Yang Yuhuan was inconvenient, so he came here earlier.

After all, it is now a matter of spring ploughing, and nothing is as important as spring ploughing, and this year's spring ploughing is going smoothly than in previous years.

Li An is the biggest hero, first of all, Li An invented black powder, so that the mining speed of iron ore has greatly increased, so that the price of pig iron has dropped a lot, and the price of iron farm tools has naturally declined, so that many people who could not afford to buy farm tools before have used farm tools, and the efficiency of farming has naturally been greatly strengthened.

In addition, Li An also improved the waterwheel, so that irrigating the farmland is a lot easier, these two things combined, so that this year's spring ploughing is much smoother than in previous years, and it is expected that the spring ploughing can be completed three days earlier, so that the people can free up their hands to participate in the imperial court's conscription.

The smooth progress of spring ploughing made Li Longji very happy, and praised all the ministers in charge of spring ploughing, of course, he did not forget Li An's merits, and in the end, Li An was pulled out alone to praise him.

Officials from Guozijian also took the opportunity to list the benefits of Ang Lee's pinyin, and said that movable type printing could be promoted soon.

The good early dynasty has become a conference to praise himself, which makes Li An a little embarrassed, but these are all facts, if there is no contribution of his own, how can Datang achieve today's results.

"Everyone, Li Shilang pulled a cart of things into the palace."

Just when the ministers were discussing movable type printing and pinyin, a little eunuch told Li Longji about Li An's transportation of a cart of things.

"Li Shilang, what good things have you come up with, and the car is full?"

Li Longji didn't wait for Li An to take the initiative to give, and asked directly.

"Your Majesty, it is a telescope developed by Weichen a few days ago, which can also be called clairvoyance, which can see things hundreds of miles or even thousands of miles away."

Ang Lee reported word by word, calmly.

"Telescopes, clairvoyance, can really make such things!"

"It's amazing to be able to see things hundreds or miles away."

"Li Shilang's ability is getting bigger and bigger, and he can even invent clairvoyance, which is too incredible."

The ministers were all fried, all of them with shocked and expectant looks, eager to experience the mystery of the telescope immediately.

After Li Longji heard this, of course, he was also very interested, and he could see things hundreds of miles or thousands of miles away, which was also amazing and unimaginable.

"Li Shilang, don't you hurry up and present the telescope."

The little eunuch saw Li Longji's eyes and hurriedly said loudly.

"Your Majesty, the space in the hall is too small and too dark, and it is not easy to use binoculars, Weichen asks Your Majesty to move outside the hall, so that you can see more clearly."

Li An clenched his fists and suggested.

Of course, Li Longji would not refuse, and immediately stood up and strode towards the outside of the Xuanzheng Palace, and all the ministers followed curiously, ready to catch a glimpse of the telescope.

This time, in order to allow all ministers to experience it, Ang Lee exaggerated fifty ten-magnification monoculars, in addition, there are five fixed monoculars with ten to fifty magnification, that is, telescopes that can adjust magnification.

Under Li An's order, Zhao Liu, with the help of a group of small eunuchs, pulled all fifty-five telescopes up, and asked Zhao Liu to set up the telescopes with a rate of fifty magnification at one time, and stacked the telescopes with a rate of ten magnification.

Li An picked up a ten-magnification telescope, explained how to use it to Li Longji and the ministers, and personally demonstrated it, and then handed the telescope in his hand to Li Longji, and at the same time, asked Zhao Liu to hand the remaining forty-nine telescopes to the ministers.

Although the number of ministers is far more than fifty, it is completely possible to experience it, and the number is absolutely sufficient.

"Your Majesty, these small telescopes, which are tenfold rated, can shorten the distance tenfold, and what is a thousand steps away looks as if it is a hundred steps away."

Ang Lee explained carefully.

"Sure enough, it's ten times closer."

Li Longji's expression was very excited, and this was still the expression that appeared after trying his best to hide it, which showed how excited he was in his heart, and the performance of the ministers was not much different, they all had a happy expression, and praised Li An for his ability to invent this magical thing.

Of course, there are also many ministers who immediately think of the great role of telescopes, those who have led troops in battle, those who think of military affairs, and those who love astronomy think of using them to observe the stars in the sky.

"Li Shilang, these binoculars set up here must be able to see farther, right?"

Li Longji is not stupid, of course he can guess that the telescope on the ground is a telescope with higher magnification, and the other ministers have also thought of it.

"Your Majesty, these are telescopes that are ten to fifty times larger, and they can adjust the magnification, which can be zoomed in by ten to fifty times and see farther."

Li Ang gave a clear introduction and explained how to operate this relatively complex high-magnification telescope, and adjusted it from 10 magnification to 50 magnification, so that Li Longji could observe and see the changes of the object.

Because of the large interval between the five fixed telescopes, some ministers who knew how to use them began to take turns to experience the thrill of fifty times the telescope, and all of them were amazed.

After learning how to operate a fixed telescope, Li Longji began to operate it on his own and observed the scenery of the entire capital. (To be continued.) )
