The weapon tycoon who traveled to Daqin

It is not easy to make a pair of sunglasses. First of all, you need to find a lot of raw materials. There is no polyethylene. You can only find metal to make glasses.

A very good mirror frame.

Then it is to find some small iron powder, copper powder. If you make color -changing glasses, it is estimated that you need to find silver. Shang Wen also has to be extracted from industrial salt. This requires a lot of chemical appliances.

The species is not the one that he is most needed. Shang Wen's left hand wrote in the notebook with his strength. And Yu Yu looked at Shang Wen's twisting action like watching a funny performance.

"Hehehe. You look like funny." Yu Yu said with a smile.

"Also say, let you write, you can't write it. Some chemical equations have to do it yourself." Shang Wen said.

"Chemical equations, oh. It is the runes you painted. Just like those squares?" Yu Yu asked.

"Painting?" Shang Wen looked at Yu Yu in question.

"Yes. It is the painting symbol, you see." Yu Yu said at the chemical equation written by Shang Wen.

"This ... forget it. If you talk about the painting, the drawing symbols." Shang Wen said helplessly.

"You draw a symbol, I will give you as a square. Put these things according to the symbols you draw." Yu Yu said that he started to take out some glassware.

"Wait." Shang Wen called.

"What's wrong? Don't believe in me." Said Yu.

"No, this is because the chemical experiments to be done today should use silver nitrate. Nitrate silver is corrosive. There is also toxicity." Shang Wen said.

"Silver sour? What is this, and poisonous." Yu Yu asked doubt.

Looking at the appearance of Yuyu's nothing. Shang Wen knew that letting a person who didn't know anything came to the laboratory. That was a very dangerous thing. He was not afraid of the jade to hurt herself.

Ignorance caused an uncontrollable result. Moreover, a certain amount of electricity must be used.

"It's silver nitrate. That thing itself is poisonous. It is not that I will not let you, but this kind of thing will invade the skin. Let the skin ulcerate." Shang Wen could only compile it by itself.

"Ah." Yu Yu repeatedly saw the appearance of nitrate and silver.

"What you said is true." Yu Yu asked.

Shang Wen didn't say anything, nodded and agreed.

"Then, then I still think of your approach. I look at it from a distance." Yu Yu seemed very afraid of experiments. Especially silver nitrate.

"Hey. However, when you extract silver, I will get another by -product. This by -product can draw you at once." Shang Wen said.

"Draw me! It turns out that you can still paint. Why don't I know. You find that your nerd, I don't know how many things I hide in my head. And." Yu Yu looked up and down.

Don't look at me like this. Shang Wen watched Yu Yu and looked up at himself.

"Say. What else do you have to hide from me. What else will you do. I will give it to me today. I think how many tricks you can get out." Yu Yu pointed at Shang Wen with his fingers.

"Oh. My God. How can I hide it from you?" Shang Wen said innocently.

"How to explain this matter?" Yu Yu asked.

"I was talking about painting. Just like the painting. Taking you down." Shang Wen explained it.

"Take it down? What do you take to take the mirror? You can draw me." Yu Yu asked.

Shang Wen heard it. Yu Yu thought a bit.

"Yes. It is a picture. Draw you on a piece of paper. It is true than a real person." Shang Wen said.

"Well." Yu Yu looked at Shang Wen. The guy said so strange. There is really this thing. Saying Yu Yu looked at Shang Wen again. But think about it. This nerd is not an ordinary person. Maybe there is really.

He once.

"What do you think of me? I don't do it quickly. I can't do it. I will take your skin alive." Yu Yu restored the attitude of the strong woman.

"Then don't make trouble. This is high temperature again. It's also electric. It's not good. Dirty." Shang Wen warned.

"I'm still unwilling to help. You hurry up!" Sitting on the sofa pretending to see Shang Wen to do experiments.

Shang Wen is not flexible in one hand. It can only be reluctant.

Shangwen first controls silver nitrate. Silver nitrate needs to react with silver at 65 % nitric acid. But silver contains certain impurities. Shangwen needs to use electrolytic to process.

It is known by the Qin people. Just like the Qin people understand the air pressure. Start the other three. The water has water voltage. The electricity. There must be a voltage. The simple voltage table appears at this time. In addition, there is a transformer. At present

It can only reduce the pressure. It cannot be booster. And the work is rough. This thing is currently in the laboratory.

It took an hour. Shang Wen extracted a bottle of silver nitrate. The jade was very impatient. The various sitting positions changed it for a while. Then you should lie down.

Do this. I did that again. Then sit down again.

Shang Wen is busy extracting bromine. It is mainly used for experiments. The actual significance is not great. It is mainly used for research. When the sea water is not produced after several crystallization of salt.

However, it is usually released as a wastewater.

"Okay?" Shang Wen was heating. Make salt water saturated. The jade couldn't wait, so I could ask.

"No. You still need to wait." Shang Wen said.

"When is it! Forget it. I'm here again in the afternoon." After that, I was about to leave. But I returned randomly. Sit down again.

"Why are you back again?" Shang Wen began to melt the glass. It was decided to add iron powder to the glass first, copper powder. These are the suction materials of the lens.

"It's boring." Yu Yu answered very simple.

"It's boring to see you. Give you a fun." Said Shang Wen took out the glass rod to burn the Mitsubishi mirror.

"What is fun?" Yiyu suddenly interested when he heard it.

"Have you ever seen the rainbow. You take a three -shot of the sun with the three prisms. You can see the rainbow." Shang Wen said.

"Really? Didn't the rainbow appear after rain?" Yu Yu asked.

"With it. When you let it appear when it appears. It listen to you." Shang Wen said.

"That's great" Say Yu clapped his hand. Shang Wen is processing.

"Take it." Yu Yu reached out.

"Wait a minute. I will give you quenching into a FRP." Shang Wen said that he started heating. Yuyu stepped forward and waited.
