Daming: The system rejected my request for salted fish

Chapter 887

But it’s different now. After Wei Wu’s explanation of chemistry just now, Doctor Xu felt that his cousin seemed to be really suitable.

That's why before going to the palace to see the doctor, he asked Wei Wu to stay here and wait for him, because he could help his cousin.

Alchemy is not a serious academic discipline, but Wei Wu’s Institute of Science and Technology is a legitimate way to success.

Think about the steam engine, think about cement, think about the finished products made by the Academy of Science and Technology. Which one is not a good thing that benefits the country and the people?

If his cousin studied diligently under Wei Wu, it would not be a big problem for him to be recorded in history in the future.

Just as Doctor Xu was thinking about this, Wei Wu suddenly spoke up:

"Well, send someone to call him over. I really want to meet your conceited cousin."

"Okay, I'll make arrangements right now."

Doctor Xu responded and then arranged for someone to go to his cousin's house to pass on the message.

About half an hour later, a figure with an impatient look on his face walked in from outside.

"Brother, I'm busy right now! Why did you call me here?"

Doctor Xu didn't care when he heard his cousin's complaints. He was already used to it.

So after Xu Miao finished speaking, Doctor Xu did not respond to him, but just stood up and said:

"You like studying the transformation of matter, don't you? I just found someone for you who might be able to help you."

"Come, let me introduce you. The person next to me is..."

After hearing Doctor Xu introduce himself, Wei Wu did not just sit there, but stood up out of politeness.

However, what happened next made him finally understand why Doctor Xu said that Xu Miao was conceited.

Because Xu Miao didn't even wait for Doctor Xu to finish his introduction and interrupted him directly.

"Brother, I don't have time to care who he is, and I don't want to tell ordinary people what I'm doing. Even if I tell him, he won't understand."

Having said that, Xu Miao suddenly turned around and looked at Wei Wu.

"I'm not targeting you, I'm just stating a fact. If you feel offended, just treat me as a lunatic."

After saying that, Xu Miao turned to look at Doctor Xu again.

"Brother, I still have a lot of things to do. If you have nothing else to do, I'll go back first."

After Xu Miao finished speaking, he turned around and prepared to leave. In response, Wei Wu smiled and gave Doctor Xu a look.

The latter immediately understood and then said:

"I'm sorry, my cousin is so conceited and doesn't know how to talk. I apologize to you on his behalf."

"It's okay, but I'm just a frog in a well who can't see how vast the sky is. I'm not that ignorant!"

As soon as Wei Wu said this, Xu Miao, who had already walked to the door, immediately turned around and looked over.

"You're saying I'm a frog in a well?"

"Is there anyone else here?"

Wei Wu deliberately turned his head and looked around, then turned his gaze back to Xu Miao and said:

"Doctor Xu is a master of medical skills. He is not a frog in a well. I can't say that I am the only one who can do that. If it's not you, then who is it?"

Hearing Wei Wu's slightly humiliating ridicule, Xu Miao's face immediately darkened.

"Who are you? What qualifications do you have to say that I'm a frog in a well?"

"Do you need an identity? Jumping to conclusions without understanding someone, isn't that the behavior of a frog in a well?"

"According to what you said, you have presumptuously concluded that I am a frog in a well. Isn't this behavior also a frog in a well?"

Xu Miao glared at Wei Wu and used the same words to refute Wei Wu, but Wei Wu spoke again just as he finished speaking.

"No, no, no, my knowledge and understanding of things are far beyond yours, so I say you can, and you say I can't."

Hearing Wei Wu's words, Xu Miao became even angrier. He was a great alchemist, yet someone dared to say such things to him.

So after Wei Wu finished speaking, Xu Miao immediately retorted.

"Oh, really? Since you say you understand things better than I do, I'd like to ask you why saltpeter can be used to make ice."

"Also, saltpeter, sulfur, and charcoal burn separately, producing only flames and smoke, but when combined together, they explode. Why?"

Wei Wu thought he would say something, but unexpectedly it was these two questions, so he asked in a confirming tone.

"That's it?"

"Humph! It's never too late to be arrogant if you can answer it."

"Okay! Then I'll answer your first question first."

Hearing Xu Miao's cold snort, Wei Wu shook his head and smiled slightly, then slowly said:

"If I were you, I would ask why saltpeter doesn't feel cool to the touch normally, but becomes cold enough to make ice when it comes into contact with water."

"I'm afraid you won't understand if I use too complicated an explanation, so I'll just tell you the answer in a way you can understand!"

"When saltpeter dissolves in water, it absorbs the surrounding heat, just like a stove in a room in winter."

"When you take the heater away, the heat is gone, and in the cold, the water will naturally condense and turn into ice."

In fact, Wei Wu wanted to say heat, but he was afraid that Xu Miao would not understand, so he could only use heat instead.

As for Xu Miao, his expression froze immediately after hearing Wei Wu's explanation.

In fact, he himself didn't know why saltpeter could be used to make ice. He had thought about it but just couldn't figure it out.

Just like Wei Wu said, it doesn't feel cool to the touch at ordinary times, but it will become very cold once it comes into contact with water.

In the past, he always believed that there was cold air hidden inside the saltpeter, which would be released once it melted in water.

But now Wei Wu's words gave him a new idea.

"That's right! Why does water have to release cold air to freeze? If it absorbs heat, it will make the surrounding area cold."

"It's like when midsummer suddenly turns to winter, which can also freeze water. But why can saltpeter absorb heat?"

Wei Wu's simple words made Xu Miao fall into deep thought because of this new perspective.

But Wei Wu did not give him time to continue thinking, but interrupted him directly.

"Now let me answer your second question: why does a mixture of saltpeter, sulfur, and charcoal explode when ignited?"
