Li Shimin's will: Li Zhi, the throne belongs to your brother

He put the binoculars in front of his eyes suspiciously.

In an instant, he felt that he had entered the age of old eyes and dim eyes ahead of time, and quickly let go of the horror in his heart, what the hell is this.

"Your Majesty, this clairvoyance is held upside down, and it can be adjusted by twisting it." Yuan Keshi hurriedly reminded him kindly from the side.

It turned out that it was reversed, not only did not achieve the effect of thousands of miles, but the scene was shrunk and blurred.

I feel that I have entered the stage of old eyesight in advance.

"Hmm!" Li Shimin's face was a little embarrassed, and the corners of his mouth twitched.

This time he turned the binoculars, one hand supported the other and slowly twisted and adjusted it, slowly placed it in front of his eyes, closed one eye, and the picture in front of him became clearer and clearer.

The expression on his face became more and more surprised, and finally the focus was adjusted.

The trees in the distant mountains and forests clearly appear in front of you, with bare trunks, small branches, and soil mixed with fallen leaves...

Everything was clearly displayed in front of Li Shimin's eyes, as if he was close at hand and within reach.

Where had he seen such a thing before, his whole face was horrified.

After removing the binoculars, a sense of distance appeared in an instant, and when I put it back on, the clear distance of the picture disappeared.

This is amazing!

"What a clairvoyance, it really is a thousand miles away."

While speaking, he suddenly remembered something, looked at the binoculars excitedly and said.

"With this clairvoyance, one can predict the enemy's opportunities and know the enemy's movements.

Knowing the enemy's movements, you can control the overall situation, use your troops to advance and retreat freely, attack and defend in an orderly manner, and win a decisive victory thousands of miles away.

It's really worthy of clairvoyance, worthy of the name, it's really a fetish! "

Li Shimin immediately understood the military use of the monocular, and wiped it carefully.

Looking around with the binoculars again, he said with a happy face: "I want to make you a general who will win a thousand miles."

"Your Majesty, you can't do it!" Master Yuan waved his hand after hearing this, and refused excitedly.

"Why can't you do that?" Li Shimin was a little unhappy when he heard it, why don't he become the Duke himself?There is such a person?

Master Yuan Ke said with shame on his face: "In fact, these are all in "Physics". You only need to understand the refraction of light to create them. How can you afford the Duke? It really frustrates me..."

"Refraction of light? Physics?" Li Shimin raised his eyebrows and turned to look at Li Tai in surprise.

It turned out that I learned it from this, no wonder Li Tai was not surprised at all.

However, the reward is still to be rewarded.

"Well... what kind of reward does Ai Qing want?"

"Actually, I think..." While speaking, Yuan Keshi became distressed and replied, "I want His Highness to help you look at your eyes."

"Eyes??" Li Shimin looked at Li Chunfeng's eyes in confusion, what's wrong with his eyes?

"I used my clairvoyance to see what is above the sun.

Who would have thought that the light would dazzle the eyes and the tears would not stop flowing, but now it always feels like there are transparent mosquitoes flying in front of my eyes, I think that there are problems with my eyes from time to time! "

After listening to Master Yuan Ke's narration, Li Tai was speechless, and the other three also lowered their heads and held back their laughter.

What a genius you are for looking at the sun with a binoculars!

After Li Shimin listened, he subconsciously looked towards the sun curiously.

Seeing this, his eyes were blurred with tears, and his eyes were bright white. He hurriedly turned his head, put down his clairvoyant, and rubbed his eyes.

When Li Tai and the other three saw this, the corners of their mouths twitched and they suppressed their smiles.

Another genius who pointed a telescope at the sun appeared!

Seeing everyone's performance, Li Shimin pretended to be calm, and said seriously: "Cough...I'm fine, but my eyes are a little sweaty, it's not a big deal."

Li Tai looked at it and wanted to laugh, but he didn't dare, so he could only bite his cheek tightly.

The dead duck has a hard mouth... and there is a little sweat in the eyes, you Li Er didn't wipe the tears from the corners of your eyes.

"Hey, let me help you take a look as a teacher!" Li Tai turned his head and went to Master Yuan Ke to check carefully.

It is very difficult to diagnose with the naked eye, but there is no problem. The symptom should be physiological floaters.

After scrutinizing it for a while, Li Tai was a little uncertain. After all, he had only treated quite a few cats and dogs, and he didn't have much experience in treating people.

Turning around, he asked Li Chunfeng who was at the side, "What do you think?"

Li Chunfeng laughed angrily, and said in a trembling voice, "Return to master, this disciple thinks there is no serious problem, this is probably a symptom of old eyesight."

The corners of Li Tai's mouth twitched, saying that his eyesight was dim, but there shouldn't be any problem, he explained in a speechless manner.

"This should be a physiological floater. If you are tired or overuse your eyes, you will feel that there are more transparent insects like mosquitoes in front of your eyes, and they will rotate with the rotation of your eyes.

But once the eyes appear bloody, or the scenery in front of you becomes colorful, black or white, it is likely to be an eye disease.

It should be fine, go back and eat more food for eyesight, and make up for it. "

Physiological floaters, I usually look at my phone a lot, and when I suddenly look up at the sky, I can see transparent bugs in my peripheral vision, but they disappear after blinking.

But once all kinds of strange colors and flashes appear, it is likely to be a bad omen before the lesion.

"My disciple, thank you, Master, for your understanding." After receiving Li Tai's diagnosis, Yuan Keshi finally breathed a sigh of relief.

"Ai Qing has to make up for it, don't overwork and hurt your eyes!"

Li Shimin rushed out after hearing this, and excitedly held Master Yuan Ke's hand: "I have high-quality ginseng antler in my storeroom, and I will give these to Aiqing."

"Thank you, Your Majesty!" Yuan Keshi saluted very excitedly, he was finally able to be reused, and finally had a bright future.

You must know that Yuan Tiangang is with Li Shimin, and can still participate in the discussion of some major events from time to time.

When it was his turn, he was directly in charge of the official position in charge of sacrifices. Priests sounded very important, but how could it be so important to deal with the dead all day long?

"Besides, I want to give you the title of Thousand Miles Lord. In the future, I will offer Ai Qing to Lingyan Pavilion. Ai Qing also asks you to build this clairvoyance for me."

"I will live up to His Majesty's high expectations." Yuan Keshi's eyes lit up when he heard the words Lingyan Pavilion.

The other three people couldn't help being envious. You must know that the people who can enter the Lingyan Pavilion are all people who have made great contributions to the Tang Dynasty. This is a very high honor.

"Come on, follow me to the blast furnace base, I want to see with my own eyes how the clairvoyance is produced."

Li Shimin looked around and said to several people.

"I obey my orders!"

"The grass people obey."

Several people followed Li Shimin to the blast furnace base in strides.

Master Yuan Ke led a group of people to a glass smelting place, where a craftsman was carefully smelting high-lead glass with a ceramic container.

"At the beginning, Chen used ice to make a rough shape to obtain the radian and focal length."

Li Shimin seemed to understand what he heard, and nodded.

"Then you can use colored glaze to smelt it. There must be no impurities or air bubbles in it, otherwise you will not be able to see the scene clearly. The most difficult thing is this colorless colored glaze."

Chapter 125 The Steam Engine

"If you want to get colorless and transparent colored glaze, it can be said to be one in a hundred."

This is very difficult, because magazines with a little metal in the glass will be stained, for example, iron will be green...

After obtaining the colorless glass, melt the colorless glass into a liquid, and gently put it into the mold until it reaches a rough shape. "

While Master Yuan Ke was explaining, the craftsmen beside him carefully and slowly poured the red glass liquid into the mold.

This is a test of technology and experience. A little carelessness will produce bubbles that are invisible to the naked eye, but if used as a telescope lens, it will appear extra conspicuous.

Master Yuan Ke led a group of people to move forward. There are many craftsmen here who are carefully polishing the glass lenses with various tools.

"After it is formed, it needs to be checked to see if it is qualified. After it is qualified, it needs to be polished and smoothed. From the very beginning to remove the jade sand, and finally to use wool and toothpaste, it needs to be polished more than a dozen times."

Finally, a group of people came to a room full of candles. The craftsman was carefully fiddling with the lens. In front of the lens was a candle and paper.

"This is?" Li Shimin looked at the craftsman fiddling with puzzlement, only to see the candle projection on the paper shaking, and suddenly felt confused.

"This is to adjust the focal length, and only after the adjustment is done can you see the scene thousands of miles away."

Master Yuan Ke led a group of people to several brocade boxes and a pair of papers.

"This is the first batch of clairvoyances that have been polished. It took a full half a month to have so many clairvoyances. These are the methods and procedures used by Shengchang to develop clairvoyance."

"..." Li Shimin picked up one casually, adjusted the focus, his face was very happy, but at the same time his brows were also furrowed.

From smelting to polishing to final molding, dozens of people were employed, and it took more than half a month, but in the end only less than ten monoculars were obtained.

This is terribly inefficient, but it has to be produced, after all, it is a military product.

It seems that we must continue to increase manpower, and we can isolate this thing for production...

Thinking of this, Li Shimin put down the binoculars, picked up the manufacturing method, and nodded with a satisfied smile in order to observe it again.

"Okay, Aiqing is really my minister. I took these away. As for the method, I will copy a copy and keep it."

As he spoke, he waved his hand, and the Imperial Forest Army behind him appeared and took away all the brocade boxes.

Only then was he satisfied, and turned his eyes to Li Chunfeng and Zhang Yajiu and asked, "How is the development of my cannon?"

"The cannon has been developed, it's just...just..." Zhang Yajiu and Li Chunfeng returned hesitantly.

"Could it be that there is some problem?" Seeing this, Li Shimin frowned, suddenly feeling bad.

Li Chunfeng hurriedly explained: "The model of the cannon has been made, but only one specific object has been made."

"Model?"

"The so-called model is like a miniature cannon.

Like shipbuilding, first build an identical boat with wood, give reference and improvement, and then build a big boat based on the structure of the boat. "

Li Tai stood up and explained.

In fact, not only modern people like models and dolls, but ancient people also like various models and dolls.

For example, the classic terracotta warriors, the pottery ship model of the Eastern Han Dynasty unearthed in Guangzhou, and the custom of asking for blessings before launching the ship model in the Mazu Temple.

Build a small boat, and then continuously improve and refer to it according to the small boat. This method is also used now.

"Take me to have a look!!" Li Shimin frowned when he heard that there were only models, but he was not too angry.

"Yes." Li Chunfeng led Li Shimin straight to a further place.

As they got closer, a group of people heard a loud "woo" sound, and then a puff of white smoke came out from behind a room.

"Is this on fire?" Li Shimin looked at the white smoke that kept coming out, and asked with some confusion.

But Li Tai's eyes lit up when he heard it, white smoke and whistle sound, could this be a steam engine?

"Is it a steam engine? Is this the steam from the steam engine?"

Li Tai looked towards the room, which seemed to be the place where he had asked them to make industrial machines.

Seeing Li Tai's question, Yang Siqi hurried forward to report: "Return to master, this is indeed the sound of a steam engine!"

"Go, go and have a look!!" Li Tai said to Yang Siqi excitedly.

Li Shimin on the side was very puzzled, and murmured: "Clairvoyance, the emperor of the cannon is calm and composed, why is the steam engine so surprised?"

"Kang Dang, crunch..." Before they got close, they heard various gears meshing and the sound of steel colliding intertwined.

As soon as they entered the door, a group of people felt a huge heat rushing towards their faces.

Looking into it, Li Tai saw a steam engine the size of a single bed standing on one side of the wall.

Next to it stood a large water tank and several wooden barrels, and on the other side was a pile of coal.

A shirtless craftsman is holding a shovel and constantly adding coal to the bottom of the stove.

The burning coal is heating the steam boiler, and the water in the boiler is constantly boiling, producing countless steam.

The steam is sent into the three cylinders, then through the valves and into the slide valve chambers, and finally pushes the pistons.

The piston moves up and down to drive the connecting rod, the connecting rod drives the flywheel, the flywheel drives the gear, and the terminal of the gear is connected to the industrial machine.

The planer on the industrial machine is cutting a piece of cylindrical metal repeatedly and repeatedly.
