    ?? Xishan, the weather has been quite good in recent days, the sun has been shining brightly, and the haze of the previous period has been swept away, making this cold winter day a little warmer.

    "Tsk, tsk, this craftsmanship is really good. The magnification of this telescope is quite good. You can see the mountains in the distance clearly."

    Liu Jin held the recently made monocular telescope in his hand and looked at the mountains in the distance carefully.

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

    Liu Jin found a few master craftsmen in the jade industry in Beijing, and asked them to polish the colorless glass according to his requirements, polish out the concave and convex areas, and then create this monocular telescope.

    "This lens is really well polished. If you tell me, I'll give you a reward. In addition, I'll tell them to 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 he didn't understand what Liu Jin was doing with such a strange thing, and he still held it in front of his eyes to look at it, Liu Jin had the final say in Xishan, and these stewards under him had no control over Liu Jin.  That was someone who had already admired him for a long time.

    "Cough cough~cough cough~"

    At this moment, there was a coughing sound outside the door. This sound was obviously made deliberately, and then a boy who looked to be eleven or twelve years old came in with a few people.

    ??This young man has sharp eyebrows and starry eyes, red lips and white teeth. He is definitely born with a good skin. More importantly, this young man has a temperament. He looks like he is the second best in the world, like a newborn calf.

    "It turns out to be Mr. Zhu~"

    As soon as Liu Jin saw the person, he immediately said with a smile that the person who came was none other than Emperor Hongzhi's son, Emperor Wuzong Zhu Houzhao. Of course, at this time, Zhu Houzhao was still a troubled boy. He didn't study hard, asked for sick leave from the teacher every day, and liked to dance with swords and guns.  The people the prince admired the most were Wei Qing and Huo Qubing.

    At this time, Zhu Houzhao was looking at Liu Jin with a smile. Next to Zhu Houzhao, several servants were dressed as the royal guards responsible for protecting Zhu Houzhao. As for the one with a white face and a butler look, it was naturally the famous Liu Jin.

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

    "Last time I heard you talk about a lot of things at Wangyue Tower, I had a lot of questions in my stomach that I wanted to ask you. I always wanted to come out to find you, but my father didn't agree."

    ¡°When I really had the chance to come out to see you, I didn¡¯t have any questions to ask. It was really strange.¡±

    Zhu Houzhao looked at Liu Jin, but he didn't mean to be polite to Liu Jin. He pulled up a stool and sat next to Liu Jin carelessly, as if you and I are very familiar with each other.

    "If Mr. Zhu has any questions in the future, you might as well ask someone to write them down, so that he won't forget them when he comes to see me next time. As the saying goes, a good memory is worse than a bad pen. This is what it means."

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

    "No, no, I don't like tea."

    When Zhu Houzhao heard this, he waved his hands repeatedly, and then looked around Liu Jin's yard. He seemed very curious, especially when he saw some strange things in Liu Jin's yard, which made him unable to sit down.  Come on, walk over quickly and start playing with it curiously.

    "What is this?"

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

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

    Liu Jin regrets not cleaning up his yard properly. There are many miscellaneous things in the yard, most of which were made by Liu Jin himself. They are things that are not available in this era.

    "Magnifying glass?"

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

    He couldn't help but touch it with his hand, and found that his hand had grown bigger. Then he put his hand in front of his eyes, looked at it carefully, and found that there was no change, so he felt relieved.

    "Interesting~Interesting~"

      Zhu Houzhao was like a child who got a new toy, having fun playing with the magnifying glass.

    ¡°Come, 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, pointed it in the direction of the sun, used the magnifying glass to focus the light on a point, and soon the paper  It was ignited.

    "Thisthis, how did you do it?"

    "Is this magic or magic?"

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

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

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

    Hearing Liu Jin¡¯s words, Zhu Houzhao took back the magnifying glass again and imitated it in a proper manner. Soon he was also using the magnifying glass to light the paper on fire, and the whole person suddenly cheered.

    "Haha~ fun, fun."

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

    "What is this again?"

    After playing with the magnifying glass for a while, he may have felt a little bored, so he glanced around again, and soon found the telescope Liu Jin put on the table, and he immediately asked curiously.

    ¡°With this telescope, you 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 use of the telescope.

    Zhu Houzhao took a telescope and looked at a place in the distance. His eyes suddenly widened. He quickly removed the telescope and opened his eyes wide, wanting to see the place in the distance with his naked eyes.

    Then he put the telescope in front of his eyes and looked around again very curiously. At the same time, he kept saying: "Fun~ fun, interesting, so interesting. You can actually see objects in the distance."  It¡¯s so clear.¡± (Remember the website address: www.hlnovel.com
