The Weapon Tycoon Who Traveled to Great Qin

Making a pair of sunglasses is really not an easy task. First of all, we need to find a lot of raw materials. Without polypropylene, we can only look for metal and other glasses frames. However, Shang Wen found another material, natural horns. This is a very good frame.

Then look for some fine iron powder and copper powder. If you make color-changing glasses, it is estimated that you will need silver halide. Shangwen has to be extracted from industrial salt. This requires a lot of chemical equipment. What is extracted from industrial salt is only a mixture, not the one that I need most. Shang Wen's left hand tried his best to write in the notebook. And Yingyu watched Shang Wen's tweaking movements like watching a comical performance.

"Hehehe. You look so funny." Yingyu said while smiling.

"Also, let you write, but you can't write it. I have to do some chemical equations by myself." Shang Wen said.

"The chemical equation, oh. It's the symbols you drew. Just like those alchemists?" Yingyu asked.

"Drawing symbols?" Shang Wen looked at Yingyu questioningly.

"Yeah. It's the drawing symbol, look." Yingyu said, pointing to the chemical equation that Shang Wen had tweaked in the notebook.

"This... Forget it. If you say draw a talisman, then draw a talisman." Shang Wen said helplessly.

"You draw the talisman, I will be an alchemist for you. Change these things according to the talisman you drew." Yingyu said as she began to take out some glassware.

"Wait." Shang Wen shouted.

"What's wrong? Don't believe me, the alchemist." Ying Yu said.

"No, no, this is because silver nitrate is used in the chemical experiment to be done today. Silver nitrate is corrosive. It is also toxic." Shang Wen said.

"Laughing sour silver? What is this, there is poison." Ying Yu asked suspiciously.

Looking at Yingyu, she didn't know anything. Shangwen knew that to let someone who didn't understand anything come to the laboratory. That is a very dangerous thing. He is not afraid of Yingyu hurting himself. But she was afraid that her ignorance would cause uncontrollable results. Moreover, a certain amount of electricity must be used.

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

"Ah." Yingyu repeatedly saw the appearance of silver nitrate after corrosion.

"What you said is true." Yingyu asked.

Shang Wen didn't say anything, nodded in agreement.

"Then, then I'll see what you do. I'll watch from a distance." Yingyu seemed to be very afraid of experimentation. Especially silver nitrate.

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

"Draw me out! So you know how to paint. Why don't I know. You found out how many things are hidden in your head as a idiot. And." Yingyu looked up and down Shangwen.

Don't look at me like that. Shang Wen looked at Ying Yu up and down and said.

"Say. You have something to hide from me. What else can you do. Take it out for me today. I see how many tricks you can make." Yingyu pointed at Shangwen with her finger.

"Ouch. My goodness. I have nothing to hide from you." Shang Wen said with an innocent look.

"How to explain painting?" Yingyu asked.

"I'm talking about taking pictures when painting. It's the same as painting. Take pictures of you." Shangwen explained.

"Take it down? What are you doing with a mirror to look at me. This way, you can draw me down." Yingyu asked.

Shang Wen listened. Yingyu thought a little way.

"Yes. It's just a photo. Draw you on a piece of paper. It's more real than a real person." Shang Wen said.

"Yeah." Ying Yu looked at Shang Wen. This guy said so strangely. There really is this thing. Speaking, Yingyu looked at Shang Wen again. But think about it. This idiot is no ordinary person. Maybe there are. tentatively. Trust him once.

"What do you think of me? Don't do it soon. I can't do it. I'll take your skin alive." Yingyu resumed the attitude of a strong woman.

"Then don't make trouble. It's high temperature again. It's electric again. I can't make it. Disfigured." Shang Wen warned.

"I'm not willing to help that. Hurry up!" Yingyu sat on the sofa pretentiously and watched Shangwen experiment.

Shang Wen is inflexible with one hand. It can only be reluctantly.

Shang Wen first produced silver nitrate. Silver nitrate needs to react with silver in 65 percent nitric acid. But silver contains certain impurities. Shangwen needs to be processed by electrolysis. The emergence of batteries can store electricity. The voltage has been known to the people of Qin. Just like, after Qin people understand the air pressure. Begin by analogy. Water has water pressure. Power that. There must be voltage. The simple voltmeter appeared at this time. In addition. There are also transformers. Currently it can only step down. Can't pressurize. And the workmanship is extremely rough. This thing currently exists in the laboratory.

It took an hour. Shangwen extracted a bottle of silver nitrate. Yingyu was very impatient. I changed various sitting positions over and over again. Then it should be lying again. Lie down and lie down. I can't afford to live. It can be seen that Shang Wen is doing this again. Do that again. Then he sat down again.

Shang Wen is busy extracting bromine on this matter. Mainly used for experiments. The actual meaning is not great. Mainly used for research. When seawater has crystallized salt several times, it can no longer produce salt. There is bromine in the solution at this time. But usually this is discharged as waste water.

"Alright?" Shang Wen was heating up. Let the brine saturate. Yingyu couldn't wait any longer and came up to ask.

"Not yet. Still need to wait." Shang Wen said.

"When will it be finished! Forget it. I will come again this afternoon." Finished. About to leave. But it came back randomly. Sit down again.

"Why are you back again?" Shang Wen began to melt the glass. Decided to add iron powder and copper powder to the glass first. These are the absorbing materials of the lens.

"It's boring." Yingyu replied very simply.

"It's boring to see you. I'll give you a fun one." As he said, Shang Wen took out the glass rod and burned the Mitsubishi mirror.

"What's fun?" Yingyu suddenly became interested.

"Have you seen the rainbow? You take a prism to take a photo under the sun. You can see the rainbow." Shang Wen said.

"Really? Didn't the rainbow only appear after it rained?" Yingyu asked.

"With it. You can show it whenever you let it appear. It listens to you." Shang Wen said.

"That's great" Yingyu clapped her hands and said. Shangwen is processing.

"Bring it." Yingyu stretched out his hand to reach it.

"Wait a minute. I will quench you into FRP." Shang Wen said and started heating. Yingyu stepped forward and waited.
