Chapter 32: This is called a telescope

Shang Wen walked out of the yard annoyed. I didn't know how to go, so I walked out of the city. Came to a river. Shangwen saw the scenery by the river better. It's not charming, in short, it's quiet. With the scenery, my mood began to calm down slowly. Don't think about the princess who messes around and messes herself up every time.

Shang Wen, who was quiet, began to walk around casually. There is a bamboo forest not far away. Shangwen feels that many ancient literati and guest writers lived in seclusion here. There won't be any masters.

Shang Wen walked up curiously and saw an old man cutting a piece of bamboo. Shangwen saw it. This small yard is filled with bamboo and some farm tools made of bamboo. It seems that this is just a carpenter. Or call the bamboo craftsman. Shang Wen didn't know what to call it in ancient times, so he had to call it first. Shangwen didn't think there was much, but he saw the cylindrical bamboo. Think of the telescope to be manufactured. Suddenly I felt that this could be a simple material for making a telescope. He turned and walked to the yard.

Haven't opened his mouth yet. The old man has noticed Shang Wen. So he said, "Is there anything wrong with this gentleman?"

Shang Wen didn't expect that the old man opened his mouth first. He just said: "In the next Qin Shangwen, I saw the old man making bamboo wares, so I wanted to ask for some advice." Shangwen said a few words nondescript, after all, he didn't know how to speak in ancient times. I have only read basic history books. There is no written in the book, it is just a historical novel. Shang Wen was thrown aside. Read physics books. Now, some regrets. I found that there was no common sense of ancient life in my stomach.

"Haha, you can't be an old man. But you can't. Sir, please come in." The old man smiled happily. Introduce Shangwen into the courtyard.

"Sit." The old man waved his hand.

Shangwen and the old man sat down by the mill table. Several exquisitely crafted bamboo stools. Let Shangwen feel that the benefits of this old man are not simple.

The old man returned to the house and brought out two bowls of water. Said: "Ordinary people. There is nothing to take out. Mr. Don't be offended."

"Nothing, nothing, I can't get used to drinking tea, it's too bitter." Shang Wen hurriedly said the tea honestly. Shangwen drank tea for the first time, and felt that it was too bitter, and he didn't know its taste. They also say it tastes good. He took a sip and almost vomited it out. Never drink again. Drink boiled water directly. Or well water.

"Haha, the gentleman seems to be a refreshing person. I don't know what old people can help." The old man said happily.

Hear the old man willing to help. I feel that this old man can talk easily.

"Old man, I want to build something called a telescope. But I need some bamboo tubes. To install some lenses. This way you can see farther." Shang Wen explained explanatoryly.

"Oh, there is this thing in the world, it's so strange. The old man can't wait. The old man is going to do it. I don't know how the husband makes it." The old man asked.

"Just put a few bamboo tubes together. That's it. It can be pulled apart." As he said, Shang Wen picked up the bamboo pieces on the ground and drew a schematic diagram.

The old man saw the diagram and said: "This is not difficult. Sir, wait a moment."

Seeing that the old man was busy making bamboo tubes, Shang Wen felt that he could not do nothing at all, and asked the old man where there is saline soil. River sand, and lime. The old man was surprised that he didn't know what Shang Wen wanted these things to do, so he said the directions of some things. Shangwen told the old man his intentions. Just went looking for something.

Came to the saline soil. Shang Wen took off his clothes and wrapped a piece of earth and rock. Lime, the old man has it, don’t look for it. Instead, he wanted to look for it. Also bring the river not far away. Shangwen dug a large hole with his hands before digging out some river sand. Wrap it in clothes. Came to the old man's courtyard.

The old man saw Shang Wen dressed like this. Feeling weird, I asked: "Sir, this is."

Shang Wen said. "You don't have to leave these things in a hurry, just take off your clothes."

"Sir, why is it so troublesome. Come on, there are still some clothes for the old man, how about putting on it, sir?" The old man hurriedly asked.

"This, this is not necessary. I still have something to ask for." Shang Wen said.

"The old man can help, just speak up. Mr. Don't be polite." said the old man.

"Thank you, old man, I want to use the stove. Can you?" Shang Wen asked.

"Yes, you can use it, sir." The old man pointed to a thatched house.

Shang Wen thanked him with a fist. Come to the stove, some simple utensils. There is still some wood piled aside. Shang Wen didn't take a closer look. Process the things you bring directly.

One morning. Shangwen extracts some sodium carbonate. Ready to start some glass making.

The old man called Shangwen to eat. Shangwen did not agree either. Because he is busy. Seeing Shang Wen's busy appearance, the old man didn't bother.

The temperature is not up to. Shangwen can only go further and add some wood. Next is to extract some charcoal. Join them. This temperature is barely ok. It turned into "water". Shangwen made a simple mold out of bamboo. It was directly made into concave lenses. Convex lenses. Shangwen didn't know which lenses to use. After the lenses cooled, Shangwen took them out carefully.

The old man saw Shangwen conjure such crystal clear things like a trick, and felt that Shangwen was not an ordinary person.

Shangwen asked the old man for a bamboo tube. Start to install the lens. The old man watched from the sidelines. Did not dare to disturb.

Shangwen installed the lens several times. Try to take a look. Finally the experiment was successful. Shang Wen looked around happily holding the telescope.

After seeing the old man's surprised look, Shang Wen let the old man take a look.

The old man took a binoculars and took a look. Shocked. Things in the distance, put them in front of their eyes. He took the binoculars and looked repeatedly. Feel incredible.

Asked: "What is this, sir, how can I see things in the distance. Could it be that Mr. has used a demon technique."

"This is a telescope. You can see far away. If you make it bigger, you can see farther away. This is the principle of light refraction." Seeing the expression that the old man did not understand. Shang Wen didn't explain it anymore.

The old man looked into the distance with his binoculars and suddenly said, "Sir, there is a team of soldiers and horses coming here. It seems to be the banner of King Qin. It is the banner of King Qin. The old man fought and saw the banner of King Qin. Yes. King Qin. It's King Qin!"

Shang Wen took the binoculars and saw King Qin's banner. The car drove fast. There is a team behind. Shang Wen is holding a telescope. See it more clearly. King Qin's expression was more anxious. I don't know what happened. Shangwen is still far away from King Qin. Forget it. forget about it.

I think I haven't eaten yet. Let the old man take it and watch it. I went to eat by myself.

Shang Wen just had a bite of rice. The old man said a word: "King Qin's carriage seems to be coming here." Shang Wen almost choked when he heard it.
