Daming Town Haiwang

Chapter 92, Telescope
Xishan, the weather has been quite good in recent days, the sun is shining brightly, sweeping away the haze some time ago, making this cold winter day a little warmer.

"Tsk tsk, this craftsmanship is really good. The multiples of this telescope are quite good, and the mountains in the distance can be seen clearly."

Liu Jin held a recently made monocular in his hand and carefully played with the distant mountains.

With colorless glass, it is relatively simple to manufacture this telescope. The principle of the telescope is also very simple. It is a kind of use of lenses or reflectors and other optical instruments to make use of the refraction of light through the lens or the reflection of light by the concave mirror. It enters the small hole and converges into an image, and then it is seen through a magnifying eyepiece.

Liu Jin found a few master craftsmen in the jade industry in the capital, and asked them to polish the colorless glass according to their own requirements, to polish the unevenness, and then create this monocular.

"The lens is polished really well. If you tell me to go on, there will be a lot of rewards. I will also inform them and polish more lenses for me."

After playing with it for a while, Liu Jin also put down the telescope and said to the steward at Xishan.

"Yes~"

Although I don't understand why Liu Jin came up with such a strange thing, I still hold it in front of my eyes and look at it, but Liu Jin has the final say on this Xishan, and these stewards under his hands are very serious about Liu Jin. That is the five-body projection that has long been admired.

"Cough~cough~"

At this moment, there was a coughing sound outside the door, which was obviously intentional, and then a boy who looked about eleven or twelve years old walked in with a few people.

This young man has sword eyebrows and star eyes, red lips and white teeth, and he has a good skin. More importantly, this young man's temperament, he looks like a newborn calf.

"So it's Young Master Zhu~"

As soon as Liu Jin saw the person, he immediately smiled and said that the person who came was Zhu Houzhao, the son of Emperor Hongzhi, Emperor Wuzong of the Ming Dynasty. Of course, Zhu Houzhao was still a troubled boy at this time. He didn't study hard. As the crown prince, the people he most admired were Wei Qing and Huo Qubing.

At this time, Zhu Houzhao was looking at Liu Jin with a smile. Beside Zhu Houzhao, the servants dressed up should be the royal guards who were responsible for protecting Zhu Houzhao. As for the white-faced and beardless, the one dressed like a housekeeper was naturally the famous Liu Jin.

Of course, the current Liu Jin is just a little eunuch next to the prince, and he is not the leader of the Eight Tigers, Eunuch Liu.

"Last time I heard you talk about a lot of things in Wangyue Tower. I have a lot of questions in my stomach that I want to ask you. I have always wanted to come out to find you, but my father disagrees."

"When I really had the opportunity to come out to find you, I didn't have any questions to ask. It's really strange."

Zhu Houzhao looked at Liu Jin, and didn't mean to be polite to Liu Jin, so he pulled a stool and sat beside Liu Jin carelessly, as if I knew you very well.

"If Mr. Zhu has any questions in the future, you might as well ask someone to write them down, so that you won't forget them when you come to see me next time. The saying goes that a good memory is worse than a bad pen, and that's what I'm talking about."

Liu Jin said with a smile, and then said to the person: "Give me a pot of good tea."

"No, no, I don't like tea."

Upon hearing this, Zhu Houzhao waved his hands again and again, and then looked around in Liu Jin's yard, seeming very curious, especially when he saw some strange things in Liu Jin's yard, he couldn't sit still. Stopped, walked over quickly, and started playing curiously.

"What is this?"

Zhu Houzhao held a magnifying glass in his hand, which was polished by Liu Jin.

"This is a magnifying glass, which can be used to magnify objects. You hold it and look at the ground."

Liu Jin regrets not tidying up his yard properly. There are many miscellaneous things in this yard, most of which were made by Liu Jin himself, which are things that do not exist in this era.

"magnifier?"

When Zhu Houzhao heard this, he immediately regained his energy. He squatted down and took a magnifying glass to look at the things on the ground. He was startled and said, "Wow~ it's getting bigger."

He couldn't help touching it with his hands, and found that his hands had also grown bigger. Then he put his hands in front of his eyes, looked carefully, and found that there was no change, so he was relieved.

"Interesting ~ Interesting ~"

Zhu Houzhao was like a child who got a new toy, playing with a magnifying glass very happily.

"Come on, let me teach you, there is something more interesting about it."

Liu Jin walked over, reached out and took the magnifying glass into his hand, then took out a piece of paper and put it on the ground, then pointed it at the direction of the sun, and used the magnifying glass to focus the light on a point, and soon the paper It was ignited.

"This... this, how did you do it?"

"Is this fairy magic or black magic?"

Zhu Houzhao and Liu Jin were all dumbfounded, as if they saw Liu Jin performing fairy magic or black magic.

"This is very simple. You see, this magnifying glass can gather sunlight together. We point it in the direction of the sunlight, and then slowly shrink this white spot, and it can ignite the paper."

Looking at the expressions of Zhu Houzhao and Liu Jin, Liu Jin is also very satisfied, coaxing the children, don't be too simple.

Hearing Liu Jin's words, Zhu Houzhao also took back the magnifying glass again, learning in style, and soon he was also using the magnifying glass to light the paper on fire, and the whole person immediately cheered.

"Haha~ fun, fun."

Zhu Houzhao carefully played with the magnifying glass in his hand, and then began to light the paper continuously, having a great time playing.

"What is this?"

After playing with the magnifying glass for a while, he might feel a little bored, and looked around. He soon found the telescope that Liu Jin put on the table, and asked curiously immediately.

"This telescope can see distant objects very clearly."

"Put it next to your eye and close the other eye."

Liu Jin looked at Zhu Houzhao, and explained the function and usage of the telescope.

Zhu Houzhao looked at the distant place with the telescope, and his eyes widened immediately. He quickly moved the telescope away, opened his eyes wide, and wanted to see the distant place with the naked eye.

Then he put the binoculars in front of his eyes, looked around very curiously again, and at the same time kept saying: "It's fun~ It's fun, interesting, so interesting, I can actually see objects in the distance. so clearly."
