The weapon tycoon who traveled to Daqin

Naofumi walked out of the yard angrily. He didn't know how to walk, so he walked out of the city and came to a river. Naofumi saw that the scenery by the river was more beautiful. It couldn't be said to be charming. In short, it was quiet. His mood also followed.

The scenery slowly began to calm down. I stopped thinking about the princess who was so messy and caused trouble for me every time.

After calming down, Shangwen began to walk casually. There was a bamboo forest not far away. Shangwen felt that many literati in ancient times lived in seclusion here. There must not be any masters.

Shangwen walked up curiously and saw an old man whittling a piece of bamboo. Shangwen saw that this small yard was filled with bamboos and some farm tools made of bamboo. It seemed that he was just a carpenter, or something like that.

Bamboo craftsman. Naofumi didn't know what to call him in ancient times, so he had to call him like this. Naofumi thought it was nothing, but when he saw the cylindrical object of bamboo, he thought of the telescope he wanted to make. Suddenly he thought that this could be a simple material for making telescopes. So he turned around.

Walk to that courtyard.

Before he opened his mouth, the old man had already noticed Naofumi and said, "What can I do for this gentleman?"

To Shangwen's surprise, the old man opened his mouth first and said: "I'm Qin Shangwen. I saw the old man making bamboo utensils and wanted to ask for advice." Shangwen said a few words that were nondescript. After all, he didn't know how to speak in ancient times.

I have only read basic history books. There is nothing written in the books, just historical novels. I have thrown all the literature aside and read physics books. Now, I feel a little regretful. I find that I have no common sense about ancient life at all.

"Haha, this old man can't be a gentleman. But I can't. Please come in, sir." The old man smiled happily and introduced Naofumi into the courtyard.

"Sit." The old man waved his hand.

Naofumi and the old man sat down at the grinding table. Several exquisitely crafted bamboo stools made Naofumi feel that the old man's income was not simple.

The old man went back to the house and brought out two bowls of water. He said: "Ordinary people don't have anything to take out. Don't be surprised, sir."

"It's nothing, it's nothing. I can't get used to tea either. It's too bitter." Shangwen quickly said about the tea honestly. The first time Shangwen drank tea, he thought it was too bitter and he didn't know what it tasted like. Others said it tasted good.

I just took a sip and almost spit it out. I never drank again. I just drank boiled water or well water.

"Haha, sir, he seems to be a cheerful person. I wonder if there is anyone who can help." The old man said happily.

When I heard that the old man was willing to help, I felt that this old man could be easy to talk to.

"Old man, I want to build something called a telescope. But I need some bamboo tubes to install some lenses. This way, I can see farther." Shangwen said in explanation.

"Oh, there is such a thing in the world. It's so strange. I can't wait to see it. I'll do it now. I don't know how to make it, sir." the old man asked.

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

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

Seeing that the old man was busy making bamboo tubes, Naofumi felt that he couldn't be idle and asked the old man where there were saline-alkali land, river sand, and lime. The old man was surprised and didn't know what Naofumi wanted these things for, so he said some

Naofumi told the old man his intentions and went to look for the things.

When they came to the saline-alkali land, Naofumi took off his clothes and wrapped a piece of earth, rocks and lime. The old man had it, so there was no need to look for it. Instead, he had to look for river sand. The river was not far away. Naofumi dug a big hole with his hands.

Dig out some river sand, wrap it in clothes, and go to the old man's courtyard.

When the old man saw Naofumi dressed like this, he felt a little weird and asked, "Sir, what is this?"

Naofumi said, "I'm in a hurry and I don't have anything to store these things, so I just need to take off my clothes."

"Sir, why are you doing this? Come on, I still have some clothes, sir. Don't mind changing them. How about changing them?" the old man asked hurriedly.

"This, that's not necessary. I have one more thing to ask for." Naofumi said.

"If you can help me, just ask. Sir, please don't be polite," the old man said.

"Thank you, old man. I would like to use the stove. Is that okay?" Naofumi asked.

"Okay, okay, sir, feel free to use it." The old man pointed to a thatched house.

Naofumi thanked him with his fists in his hands. He came to the stove, where some simple utensils and some wood were piled aside. Naofumi didn't look carefully and just processed what he brought.

All morning, Naofumi refined some sodium carbonate and prepared to start making glass.

The old man called Naofumi to come for dinner. Naofumi didn't agree because he was busy. The old man saw that Naofumi looked busy, so he didn't bother him.

The temperature could not be reached. Naofumi could only go further and add some wood. Then he extracted some charcoal and added it to it. After the temperature was barely enough, it turned into "water". Naofumi made a simple mold with bamboo slices and made it directly into a concave lens.

.Convex lenses. Naofumi didn’t know which lenses to use. After the lenses cooled down, Naofumi carefully took them out.

When the old man saw Naofumi conjuring such crystal clear objects, he felt that Naofumi was not an ordinary person.

Naofumi asked the old man for a bamboo tube and began to install the lenses. The old man watched from the side and did not dare to disturb him.

Naofumi installed the lens several times and tried to take a look. Finally, the experiment was successful. Naofumi happily looked around with the telescope.

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

The old man took a telescope and looked at it. He was shocked. He put the distant things in front of his eyes. He took the telescope and looked at it repeatedly. He felt incredible.

Asked: "Sir, what is this? How can I see things in the distance? Could it be that you have cast a magic spell?"

"This is a telescope. It can see distant places. If it is bigger, you can also see farther places. This is the principle of light refraction." Seeing the old man's incomprehensible expression, Naofumi stopped talking.

The explanation continues.

The old man looked into the distance with a telescope and suddenly said: "Sir, there is a group of soldiers and horses in the distance coming this way. It seems to be the flag of King Qin. It is the flag of King Qin. I have fought in the war and seen the flag of King Qin. It is.

The King of Qin. It’s the King of Qin!”

Shang Wen took the telescope and saw the flag of King Qin. The car was driving very fast. There was a group of people behind it. Shang Wen took the telescope and could see more clearly. King Qin's face was anxious. He didn't know what was going on. The distance between Shang Wen and King Qin was

It's still quite far. Forget it. I don't want to think about it anymore.

Thinking that he hadn't eaten yet, he asked the old man to take a look at it and went to eat by himself.

Shangwen had just taken a bite of rice when the old man said: "King Qin's chariots and horses seem to be coming this way." Shangwen almost choked when he heard this.
