Shang Wen walked out of the courtyard in annoyance. I didn't know how to get there, so I walked out of the city. Come to a river. Shang Wen saw that the scenery by the river was more beautiful. It's not charming, it's quiet. My mood began to calm down slowly along with the scenery. Don't think about the princess who messes around and makes trouble for herself every time.

Shang Wen, who had quieted down, began to walk casually. There is a bamboo forest not far away. Shang Wen felt that many literati and artists in ancient times lived in seclusion here. There won't be any masters.

Shang Wen walked up curiously, only to see an old man, cutting a piece of bamboo. Shang Wen saw. This small yard is full of bamboo, and there are some farming tools made of bamboo. It seems that this is just a carpenter. Or call it a bamboo craftsman. Shang Wen didn't know what to call it in ancient times, so he had to call it first. Shang Wen felt nothing, but saw the cylindrical object of bamboo. Think of the telescope you want to make. Suddenly, I thought that this was a simple material that could be used to make telescopes. Then he turned and walked to the courtyard.

I haven't opened my mouth yet. The old man had already noticed Shang Wen. He said, "Is there anything wrong with this gentleman?" ”

Shang Wen didn't expect that the old man opened his mouth first. said: "In Xia Qin Shangwen, I saw the old gentleman making bamboo, so I wanted to ask for advice." Shang Wen said a few words indecently, after all, he didn't know how to speak in ancient times. I have only read basic history books. It's not written in the book, it's just a historical novel. Shang Wen tossed aside. Read physics books. Now, there are some regrets. found that in his belly, there was no common sense of ancient life at all.

"Haha, old decay can't be a gentleman. But no. Sir, please come in. The old man smiled happily. Introduce Shangwen into the hospital.

"Sit." The old man waved his hand.

Shang Wen and the old man sat down by the mill. Several intricately crafted bamboo stools. made Shangwen feel that the benefits of this old man were not simple.

The old man went back to the house and brought out two bowls of water. Said: "Ordinary people. Nothing to take out. Don't be surprised, sir. ”

"It's nothing, it's nothing, I'm not used to drinking tea, it's too bitter." Shang Wen hurriedly and honestly talked about tea. The first time Shang Wen drank tea, he felt that it was too bitter and didn't know what it tasted like. People also say it's delicious. I took a sip of it myself and almost threw it up. I never drank it again. Drink directly from boiled water. Or well water.

"Haha, Mr. seems to be a cheerful man. I don't know if there's anything old and old that can help. The old man said happily.

I heard that the old man was willing to help. I feel that this old man can talk well. "Old man, I want to build something called a telescope. But some bamboo tubes are needed. to install some lenses. This way you can see farther. Shang Wen said explanatorily. Oh, it's so strange that there are such things in the world. The old decay is a little impatient. Decay will do it. I don't know how to make it. The old man asked. It's just a few bamboo tubes put together. That's it. Able to pull apart. As he spoke, Shang Wen picked up the bamboo piece on the ground and drew a schematic diagram.

The old man saw the schematic diagram and said, "This is not difficult. Wait a minute, sir. ”

Seeing that the old man was busy making bamboo tubes, Shang Wen felt that he couldn't be idle and had nothing to do, so he asked the old man if there was saline-alkali land. river sand, and lime. The old man was surprised and didn't know what Shang Wen wanted for these things, so he said the location of some things. Shang Wen told the old man his intentions. So I went looking for something.

Come to the saline land. Shang Wen took off his clothes and wrapped a piece of earth and stones. Lime, the old man has it, you don't have to look for it. Instead, the river sand should be sought. There is also a river just around the corner. Shang Wen dug a large pit by hand to dig out some river sand. Wrap it up in clothes. Come to the old man's courtyard.

The old man saw Shang Wen dressed like this. I felt a little unbelievable and asked, "Sir, this is." ”

Shang Wen said. "If you are in a hurry, you don't have those things to put these things, just take off your clothes."

"Sir, what a problem with this. Come on, the old decay still has some clothes, how about not dislike it and put it on, sir? The old man hurriedly asked.

"Well, it doesn't have to be. I have one more thing to ask for. Shang Wen said.

"The old man can help, just ask. Sir, don't be polite. The old man said. Thank you, old man, I want to use the stove. May I? Shang Wen asked. Yes, sir, use it. The old man pointed to a thatched hut.

Shang Wen clenched his fists and thanked him. Just come to the stove, some simple utensils. There are also some lumbers piled on the side. Shang Wen didn't look closely. Directly process what you bring with you.

One morning. Shangwen refines some sodium carbonate. Ready to start some manufacturing glass.

The old man called Shang Wen to eat. Shang Wen didn't agree. Because he's busy. The old man saw that Shang Wen was busy, so he didn't bother.

The temperature is not reached. Shang Wen can only go further, add some wood. The next step is to extract some charcoal. Join in. This temperature is barely okay. before it turns into 'water'. Shang Wen made a simple mold out of bamboo chips. Directly made into concave lenses. Convex lenses. Shang Wen didn't know exactly what lenses to use. Wait for the lenses to cool down. Shang Wen carefully took it out.

The old man saw Shang Wen conjuring up such a crystal clear thing, and felt that Shang Wen was not an ordinary person.

Shang Wen asked the old man for a bamboo tube. Start attaching the lenses. The old man watched from the sidelines. Didn't dare to make a noise to bother.

Shangwen had the lenses fitted several times. Tried to look at it. Finally, the experiment was successful. Shang Wen happily took the telescope and looked around.

Then seeing the old man's surprised look, Shang Wen asked the old man to take a look.

The old man took the binoculars and looked at it. Shocked. Things in the distance, put them in front of your eyes. I took the binoculars and looked at them repeatedly. I think it's incredible.

He asked, "Sir, what is this, and how can you see things in the distance?" Mr. Mo Fei cast a demon spell. ”

"It's a telescope. Being able to see in the distance. If you make it bigger, you can see it from a farther distance. This is the principle of refraction of light. Seeing the old man's incomprehensible expression. Shang Wen didn't explain any further.

The old man looked into the distance with a telescope and suddenly said, "Sir, there is a group of soldiers and horses coming this way in the distance." It seems to be the banner of King Qin. It is the banner of the King of Qin. The old man has fought and seen the banner of King Qin. It's the King of Qin. It's King Qin! “

Shang Wen took the binoculars and saw the banner of King Qin. The car was speeding up. There was also a team of men in the back. Shang Wen holds the binoculars. It can be seen more clearly. King Qin's face was more anxious. Not sure what happened. Shang Wen is still far away from King Qin. Never mind. I don't want to.

Thought of not having eaten yet. Let the old man take it and look at it. I went to eat by myself.

Shang Wen had just taken a bite of food. The old man said, "King Qin's chariot and horse seem to be coming this way." Shang Wen almost choked when he heard this.
