"I also said that I asked you to write, but you couldn't write it. I have to do some chemical equations myself." Shang Wen said.

"Chemical equations, oh. Those talismans you drew. Just like those alchemists?" Ying Yu asked.

"Painting talisman?" Shangwen looked at Yingyu questioningly.

"That's right. It's just a symbol, look." Ying Yu said, pointing to the chemical equation that Shang Wen had written in his notebook.

"Forget it. If you say draw a talisman, then draw a talisman." Shangwen said helplessly.

"You draw the talisman, and I'll be an alchemist for you. Make these things out according to the talisman you drew." Yingyu said and began to take out some glass vessels.

"Wait." Shangwen called.

"What's the matter? You don't believe me as an alchemist." Ying Yu said.

"No, it's because silver nitrate is used in the chemical experiment to be done today. Silver nitrate is corrosive and poisonous," Shang Wen said.

"Laughing acid silver? What is it? It's poisonous." Ying Yu asked suspiciously.

Seeing that Ying Yu didn't know anything.Shangwen knew it, let a person who didn't understand anything come to the laboratory.That is a very dangerous thing.He was not afraid that Ying Yu would hurt himself.It was because she was afraid that her ignorance would lead to unmanageable results.Moreover, a certain amount of electricity will 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 and make the skin fester." Shang Wen could only compile it by himself.

"Ah." Ying Yu repeatedly saw the appearance of silver nitrate corrosion.

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

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

"Then, then, I'd better see what you do. I'll watch from a distance." Ying Yu seemed very afraid of the experiment.Especially silver nitrate.

"Hey. However, when extracting silver halide, I will get another by-product. This by-product can draw you in one fell swoop." Shang Wen said.

"Draw me! So you can draw. Why didn't I know. You found out that you are an idiot, and you don't know how many things are hidden in your head. And." Ying Yu looked Shang Wen up and down.

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

"Tell me. You still have something to hide from me. What else can you do? Show me everything today. Let's see how many tricks you can come up with." Ying Yu pointed at Shang Wen with her finger.

"Oh, my God. I have nothing to hide from you." Shangwen said with an innocent face.

"How do you explain the matter of painting?" Ying Yu asked.

"Painting I mean taking pictures. Just like painting. Take a picture of you." Shangwen explained.

"Photograph it? Why are you taking a mirror to look at me? Just take a picture like this. You can draw me down." Yingyu asked.

Shangwen heard it.Ying Yu thought of something.

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

"Hmm." Ying Yu looked at Shang Wen.What this guy said was so strange.There really is this thing.As she spoke, Ying Yu looked at Shang Wen again.But think about it.This idiot is no ordinary person.Maybe there is.tentatively.Believe him once.

"What do you think I'm doing? Don't do it quickly. I can't do it. I'll take your skin off." Ying Yu resumed her attitude of a strong woman.

"Then don't make trouble. It's high temperature again. It's electric. It can't be done well. Disfigurement." Shang Wenjing warned.

"I'm not willing to help that yet. Hurry up!" Ying Yu pretended to sit on the sofa and watch Shang Wen do the experiment.

Shang Wen was not flexible with one hand.It can only be forced.

Shangwen first produced silver nitrate.Silver nitrate needs to react with silver in 60.00% five nitric acid.But silver contains certain impurities.Shangwen needs to use electrolysis to process.The emergence of batteries can store electricity.Voltage has been known to the people of Qin.Just like, after the Qin people learned about air pressure.Start to infer other cases from one instance.Water has pressure.Power that.There must be voltage.The simple voltmeter appeared at this time.besides.And the transformer.Currently only down pressure.Cannot be supercharged.And the workmanship is extremely rough.This thing currently exists in the lab.

It took an hour.Shangwen extracted a bottle of silver nitrate.Ying Yu waited impatiently.Various sitting postures have been changed.Then it's time to lie down.Lie down lie down.I can't afford to get up.It can be seen that Shangwen is doing this again.Do that again.Then he sat down again.

Shangwen is busy extracting bromine.Mainly used for experiments.The practical significance is not great.Mainly used for research.When seawater crystallizes out salt after several times, it can no longer produce salt.At this time, there is bromine in the solution.Usually, however, this is discharged as waste water.

"Are you ready?" Shangwen was heating up.Let the brine saturate.Ying Yu really couldn't wait any longer, so she came up to ask.

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

"When will it be over! Forget it. I'll come back in the afternoon." Finished.about to leave.But it comes back randomly.Sit down again.

"Why are you back?" 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.

"Nothing." Ying Yu replied simply.

"It's boring to see you. Here's a fun one for you." As he said, Shangwen took out a glass rod and fired a [-]-sided mirror.

"What's so fun?" Ying Yu immediately became interested.

"Have you ever seen a rainbow? Take a prism and take a photo under the sun. You will be able to see the rainbow." Shang Wen said.

"Really? Doesn't the rainbow only appear after it rains?" Ying Yu asked.

"With it. You can let it appear whenever you want. It listens to you." Shangwen said.

"That's great," Ying Yu clapped her hands and said.Shangwen is processing.

"Bring it." Ying Yu reached out to ask for it.

"Wait a minute. I'll quench it into fiberglass for you." Shangwen said and started heating.Ying Yu stepped forward and waited.

500 sun sets

"Red, yellow, blue, green..." Ying Yu held a prism and counted the seven colors of the rainbow.

"Ah. Seven colors." Ying Yu shouted after counting.Ying Yu at this time is like a three-year-old child who is curious about everything.

"Hey. Where is the princess doing?" A female office worker asked.

"I don't know. I guess the prime minister is looking for something new to coax her." Another female companion who was traveling with him replied.

"Our prime minister really protects the princess. I think they are a good match," said the female office worker.

"That's not true," said the companion.

Ying Yu looked left and right with the prism alone.After playing for a while, I feel that it is not interesting.

"Hey. You two come here. This princess will give you two good things." Ying Yu called out when she saw two female office workers who were muttering in the distance.

"I've seen the princess." The two stepped forward to salute.

"Get up!" Ying Yu said.

"Look." After speaking, Ying Yu took a prism and placed her hand under the rainbow.

"Yeah. This..." The two looked at the rainbow that appeared in surprise.
