From Chief to Ball

Now that things are up, there is no need to ask about irrelevant things anymore, and the topic has become more direct.

"Chen Jian, you should have guessed the purpose of my visit this time, right?"

"Yes."

"My husband likes your lab report very much, and is also very curious about that strange wax-like thing. So I want to see how you made it."

Speaking of this, Li Yun took out a piece of paper from her arms, with some words printed on it, as well as Mr. Mu's seal, to prove her identity and purpose.

Chen Jian looked at it, and actually he didn't quite understand it, but he already believed it [-]% to [-]% in his heart.After all, Li Yun didn't come to look for her alone, but came to her home and waited for a few days.

"See? If you can repeat your experiment, Mr. Mu can recommend you to study in the academy. This is a rare opportunity."

After saying this sentence, Li Yun suddenly said: "If it is true, then you are my junior brother. I am very happy, and my husband will be very happy too."

"But if it's false, please tell me. I don't want my husband's hopes to turn into soap bubbles. He is too old and in poor health. I don't want to make my husband angry because of a lie. If the husband because of this sentence If something happens to the lie, I swear I will hate you. And even if you are false, you will understand, don’t provoke a person who studies mineral chemistry to hate you.”

Chen Jian understood the threat in the words, and he also heard the respect and love for Mr. Mu in the words, so he smiled and nodded: "I understand."

"That's good. Mr. was blown off his fingers in order to find a solution to the problem that a new type of saltpeter gunpowder was easy to absorb moisture. I died that time. Two of my classmates died, so I have seen blood and death, and also Please don't take my words as a joke."

Li Yun didn't say anything more, Chen Jian led the way, and the two came to Chen Jian's small and simple laboratory.

In the hut, Chen Jian skillfully repeated the previous process, and there were still a lot of ground ashes, silica and charcoal powder left.

While operating, he explained: "I thought at the time, since charcoal can extract iron from iron ore, maybe it can also extract things from bones..."

Li Yun didn't speak, but watched Chen Jian's actions, and listened to Chen Jian's seemingly reasonable explanations, until finally he saw those pale yellow wax-like solids reappear from the bottom of the water.

Chen Jian wanted to collect it, but Li Yun stopped him.

Looking at the extremely crude experimental equipment in the simple log cabin, a feeling called moving sprouted in Li Yun's heart.

As the group of people who are jokingly called the fastest runners in the academy, Li Yun is very clear about what kind of subject she is studying, and also knows how many colleagues and ancestors have died in it for hundreds of years.

The young man in front of him, who looked like he was smiling and seemed to be indifferent to everything, together with these simple utensils, pottery or porcelain, and few glass bottles, made Li Yun imagine a respectable scene.

He seemed to see a young man frowning in a simple wooden house, burning and heating all kinds of strange minerals in these vessels that could be fried at any time, eager to find a new thing that could explain the world .

He thought of the description in the experiment report about the highly toxic solid and the smell of garlic, as if he saw that the young man didn't know how to cool the collection with water at the beginning, but let the highly toxic steam fill the room, and the room was filled with A smell of garlic.But he realized that this smell was not garlic, but a poison that could kill a big dog in pain.

Thinking of the scribbled characters on the paper, he seemed to see a young man shouting excitedly from those flying words, and he saw a young man hunched over countless days and nights, repeating boring and highly poisonous experiments step by step. .

Even, he seemed to see the burning fire. After seeing the burning fire, the young man was not nervous but observed the smoke and dust after the burning. In the candlelight replaced by the poisonous fire, he wrote "The burning will produce a strong fire." "White smoke" is the simplest and full of stories.

What's more, he seems to have seen young people studying all kinds of books in this wooden house far away from the bustling, guessing their own conclusions. The reason for doing this experiment may be to find out why cattle and sheep grow bones and why Eating grass can grow bones, so we can know what affects the production of flowers, fruits and grains...

Just like the play called Orphan that Li Yun had heard and watched, he didn't understand why his junior brother would write such a thing.

But seeing all this now, he felt that he understood.

He felt that that scene was the little junior brother expressing his feelings—no matter what kind of failure, no matter how many times of destruction, it would never crush a heart with ideals in it.

He felt that, as said in that scene, all of this was for self-realization as well as to make China better: the orphan in the play chose politics, so that the blood of the same race would no longer be shed meaninglessly—and Xiao The younger brother chose to let the land produce more food, so that fewer people of the same clan would go hungry.

At least, he moved himself in this way, and used this feeling to speculate on Chen Jian, so it was logical, and he was even more moved.

Chen Jian was still talking, and Li Yun was still listening, but when Chen Jian said he was tired, Li Yun stretched out his hand and pressed Chen Jian's shoulder, signaling him to stop talking.

"Junior brother, I can only say that your luck is really good. Mr. told us not to rely on guesswork to explain something, because guesses are always inaccurate. But many of your guesses are right. Before you came, Mr. Ma was also moved." After all, it is sometimes necessary to guess.”

Li Yun smiled and said that one of Chen Jian's "guesses" was confirmed.That is, bones and shells look alike, so Chen Jian "guessed" that there were things in the ashes as well as in shells and lime.

For the test, Chen Jian did not have those reagents, so he wrote them in the form of guesses on the paper sent to the academy.The messy equipment in the academy was left behind by him or made later due to constraints, so he knew very well that there must be hydrochloric acid in the academy.

So he used hydrochloric acid to dissolve the ashes under the pretext that bones and shells look alike, and the filtrate reacted with sodium carbonate to form a precipitate.It decomposes after heating, and produces slaked lime after adding water, which proves that the bones contain calcium that is not called calcium today.

In addition to the acidity of white phosphorus dissolved in water, and the popular dualism of acid-base yin-yang at that time, it can be speculated that bones are actually a combination of phosphorus and calcium in the form of an acid-base binary.

It can be proved that the bones contain phosphorus and calcium, which is very important for some industries.For example, adding some lime to the fermented feed for raising cattle will make the cattle grow taller. Apart from the purpose of fermentation itself, it also solves the problem of knowing it but not knowing it: it turns out that it is to make the cattle grow bones better.

This is not just a bottle of white phosphorus and two experiments, but a series of problems that have been solved. Although some of them are "guesses" that Li Yun doesn't like, Li Yun, who was moved by her "guesses" and fantasies, This little dislike has been forgotten.

"Junior Brother, I want to congratulate you. You will become the youngest person to be named on the Shrine of the Sage in 200 years. Now that you have proved that you have done all this, the last doubt of my husband will be dispelled. He has been upright all his life, He will not easily recommend others to enter the academy to become his disciple, you are one of the few."

"I think, sir, he will be very happy to receive a disciple like you in his later years."

Chen Jian let out a cry, pretending to be excited and shouting, showing the behavior a young man should have when he hears such good news.

Some are exaggerated, some are contrived, but in Li Yun's view, this is normal. If you know that such news is still as calm as a windless pond, then there is a problem.

After yelling, Chen Jian cheekily called his senior brother, and greatly appreciated Mr. Mu's achievements from those books.

He has a high level and knows a lot, so he sees things from different angles, and he always speaks to the point with compliments, which is what Mr. Mu is most proud of.Disciple Li Yun often heard about it, and when Chen Jianyi said it, he suddenly felt that this junior was very good. What he said was absolutely in line with the master's wishes, and he also got a little close to this junior who became famous at a young age but was not proud.

In fact, Chen Jian's praise was sincere, and he admired this kind of person who studied hard.He is a plagiarist, and Mr. Mu is the one who breaks out the lightning from the darkness, so he cannot help admiring him.

However, Chen Jian had a different idea about going to the academy, so he said: "Brother, I really like to listen to my husband, but... just can I go again in two years? I am here. There are other things."

Li Yun frowned and said with a smile: "Junior brother, I have heard about your reputation in Mincheng these days. You are young and have a name for your play. For young people, this is indeed better than boring study. But I think it's better for you to go to the Academy. Even though you know a lot, maybe better than me, but there are some things you can't prove here. It's like the 'calcium' in the ashes, you only need to be here It can be guessed, even if it is true, it cannot be proved.”

"When you are there, you can better understand and explain the world. Isn't this your dream?"

Chen Jian nodded and said, "This is exactly my dream, but I'm afraid it's not the same as what my brother thinks."

"How to say?"

"I don't know why the senior brother wants to learn these things?"

"Because I've loved it since I was a kid."

"Then are there many people in the academy studying with Mr.?"

"not much."

"So what are people willing to learn?"

"Management, laws and regulations, judiciary, etc. These are still very useful when taking the office officer exam. It is always difficult for those who learn from us to make money and get promoted. Therefore, there are actually not many people."

"So... I hope that in the future there will be more people studying our subject than now."

"Why?"

"earned money."

"Money is not the best ideal."

"But the dream of most people."
