Practicing Medicine in Three Kingdoms

To process activated carbon, the most important thing is not chemical materials, but a space as closed as possible and a relatively precise temperature.However, the judgment of temperature in this era is basically still at the empirical level of "seeing the ice in a bottle and knowing the cold in the world", lacking a precise and clear scale.

Li Yinzhou was squatting in the corner, fiddling with the eight taels of gold in front of him boredly. It is hard for a smart woman to cook without rice. Even cutting-edge technology out of the matching production level is nothing but empty talk.

For the first time, he missed the desolate and depressing laboratory so much. Even the smelly and crowded big white and small white nests are hung with precise temperature and humidity monitoring instruments. Inject a powerful driving force into life.

Only when we are far away from the advanced technical level can we realize how many giants have stepped on our feet. Scholars who can innovate in the scientific field of this era are all great craftsmen who have made the cornerstone with flesh and blood.

The hot-blooded impulse gradually faded, and the calm thinking gradually went back.

On the verge of giving up and struggling and jumping repeatedly, Li Yinzhou picked up a flat piece of broken gold, with the protruding side as the top and the concave side as the back, twisted his two fingers, closed his eyes, and threw it up with force from his wrist.

The spread fingers didn't feel any weight, and after a while, he opened his eyes suspiciously——

There was only a clean and white hand in sight, with five fingers clenched across his forehead.

Ink is hanging on the tip of the nose.

A warm breath came from the neck: "Why are you so preoccupied?"

Li Yinzhou's heart suddenly jumped as if he was stepping on a ladder, and his body tensed subconsciously. After realizing who was behind him, he helplessly relaxed his straight shoulders and sighed slowly: "Young master, don't tease me anymore. .”

The slightly angular gold nugget was pressed into the palm of his hand, and Lu Xun moved his five fingers slightly. Just when Li Yinzhou thought he was going to return it to him, he saw him retract his hand, straighten his body, and said with a smile in his voice: "I brought you the bibliography, Why don't you use this as your reward."

... What about the delivery?

Li Yinzhou gritted his teeth slightly, turned his neck, and looked up at the other's delicate chin, feeling a little funny: "Young Master's Mansion can't be so cheap, right?"

Lu Xun returned with a slight smile: "Mr. Zhang is not so stingy with you, is he?"

Li Yinzhou was speechless.

He could probably guess the intention of the other party's move, but he didn't want to be too sympathetic. Lu Xun taught him to write just to push

The smooth flow of human affection that fuels the flames, and one step closer is the heart-to-heart talk that only friends can do.

But neither Sun Quan nor Lu Xun are suitable to be friends.

Sun Quan is a wolf cub, and Lu Xun is a little fox. One doesn't dare to offend, and the other just can't play.

He changed the topic calmly: "I didn't throw gold to make a decision because I was hesitant, but it was just for fun, so take it away if you want, young master."

Lu Xun looked at him without saying a word, and after a while, he lowered his wrist, with no displeasure on his face: "I brought you "Shuowen Jiezi", and you can tell me if there are any other books you want. The prefect's mansion is the place with the largest collection of books in Lujiang City."

Li Yinzhou was half joking: "Young master's books are too expensive, and the villain can't afford them."

Lu Xun rarely showed a trace of childishness, his eyes slightly curved: "You get what you pay for."

The words were a joke, but Li Yinzhou was a little moved. The Lu family is a well-known scholarly family in Jiangdong, with a huge collection of books. Maybe there are some technical books for reference.

He looked down seriously: "Young Master, do you know what books are popular?"

Asking this question, Li Yinzhou also felt that it was too embarrassing for the other party. Although the descendants of Lu and Gu are well-known for being well-read, they must have read classics such as the Four Books and Five Classics at this age. Sun Quan, who is one year older, has not read it yet. How could Lu Xun know these miscellaneous books after reading "Six Secret Teachings" Art of War?

But I didn't expect that the other party lowered his eyes and thought quietly, and really gave the answer: ""Kao Gong Ji" once recorded a little record, but I only read the part about copper smelting, and I am not proficient in the rest."

...Are all the top scholars in this era so omniscient?

Li Yinzhou suddenly felt that those child prodigies boasted by modern times were nothing compared to the precocious children of this era.

Lu Xun obviously saw his surprise, so he didn't use it to be arrogant, but patiently said: ""Kao Gong Ji" is related to people's livelihood, and it is not a miscellaneous book. Since my grandfather cherished the people, he taught us to read it from the beginning of literacy."

Indeed, what is related to copper smelting is the manufacture of coins, and the economy is the backbone of people's livelihood. Lu Kang has always strictly trained Lu Xun as an heir. It is not surprising that he has instilled these basic knowledge since he was a child.

His precocious wisdom is not a talent given by God, but Lu Kang carved it out bit by bit according to his young appearance. He is young and has not made any mistakes.A precocious child like Sun Quan is always confused and fragile, but this child has been wrapped in an airtight cocoon, and put on a modest and gentle mask. No one knows what is going on in his heart.

What does it look like.

Perhaps the fire of the company decades later really burned away all the shackles that Lu Kang, the Lu family, and Jiangdong's aristocratic families gave him.

Among several acquaintances, Li Yinzhou is the only one who can't fully understand Lu Xun. Therefore, he doesn't reject making friends with him, but he doesn't dare to have a heart-to-heart relationship with him.

He picked up another gold leaf and handed it to Lu Xun, using a joke to cover up his alienation: "I don't know how much the young master's "Kao Gong Ji" is worth?"

Lu Xun was silent for a moment.

After a while, a gentle smile appeared: "It's worth an answer that doesn't lie to me."

Li Yinzhou's hands almost trembled, as if the darkest thoughts in his heart were easily stripped away and punished, and were grandly exposed under the eyes of the other party.

He coughed lightly to cover up his embarrassment: "...what does the young master want to know?"

If it was just to test him again, it would be perfunctory, but Li Yinzhou stared at his calm eyes, and couldn't feel a trace of oppression that he should have.

After a brief silence, he heard his calm voice.

"Want to know what you were thinking just now."

----

The afternoon is extremely long, the floating dust flickers in the bright light, and the books with the ancient bamboo fragrance are piled up into a thick pile, suppressing the impetuous mood for the time being.

Li Yinzhou turned the cold bamboo bones, but somehow felt his fingertips were hot. Lu Xun's words from before were still in his ears——

"When you want to tell me."

The handwriting under his finger passed before his eyes one by one, but those words were still repeated in his mind. For some reason, an unreasonable thought suddenly came to his mind.

——Is that kid really just wanting to make friends?

He immediately flicked his ears, and put away these distracting thoughts for the time being. Even if Lu Xun wanted to make friends, the person should be a child of the family, and had nothing to do with him, an ordinary little drug boy.

The most important thing right now is to figure out how to make activated carbon.

He has no interest in saving sentient beings, nor does he have the passion for scientific research that burns his life like Zhang Ji, but he only has the capital to settle down if he has a skill, and he doesn't want to rely on his teacher's professors for the rest of his life.

Although I can't understand all the characters, but compared with "Shuowen Jiezi" for a long time, I can barely recognize a few words representing colors. the temperature of the fire.

colour.

He slapped his forehead suddenly, how could he lose the most basic things.

Years of dependence on instruments and data has indeed been simplified, making

The output of trivial work is concise numbers, but the numbers themselves cannot replace the essence of things. Even if the required temperature cannot be accurately obtained, the degree of fire can be determined by observing the properties.

Even if it cannot be compared with modern refined industries, it is definitely much more efficient than the occasional output in charcoal making.

He bypassed this hurdle, and suddenly felt that the mountains and rivers were restored, and the willows were dark and the flowers were bright. Holding the eight taels of gold that Zhang Ji generously gave him, he already had a plan in his heart.

----

In the east of Lujiang City, Changliu Yiyi.

The slender branches fluttered the door curtain woven of bamboo strips, and through the thin strips, they seduced the students studying hard inside with blurred and swaying shadows.

This is the largest official school in Lujiang, and it is known as Xiaohou School with the fourth surname Xiaohou.If an uninformed northerner came, he would have to ridicule that Xiao Houxue, who had four surnames in Luoyang City, had already brought a small character, and adding another small character would be too shabby.

The local people have their own local rhetoric. The four-surname Xiaohou School was originally an official school set up in the past for the children of the four surnames Fan, Guo, Yin, and Ma. Because these four families are prominent, they are not listed. Hou, so he was called "Xiaohou" at that time.

In the land of Jiangdong, there are also four aristocratic families with profound histories and the same spirit. Although they cannot be compared with the power of the four surnames Xiaohou, these four families are prosperous and united, and their strength must not be underestimated.

So this small word is just the self-effacing of the scholarly family. In the land of Jiangdong, they dare not offend the children of these four families casually.

Naturally, the Xiaohou school with the fourth surname is not only the exclusive privilege of the students of these four families. Other big families, such as the Zhou family, or new forces such as the Sun family, can come here to study.

Sun Shangxiang pretended to be a boy, and often hang out in it. There is a domineering elder brother and a cold and serious second brother. No one dares to find anything about her.What's more, the young masters of Lu and Gu, two of the four great families, are on good terms with her, and even the teacher who teaches doesn't bother to persuade her, so she just turns a blind eye.

She had just recovered from a serious illness recently, and she lost her decadent sickness, and jumped up and down again, muttering about the strange things she saw every day, thinking about solving the mysteries of the world all day long.

"Have you heard that there are ghosts behind Nanshan Mountain?" She has clever eyes, and there is a kind of playfulness and vividness in her gaze, and she describes it vividly, "Some villagers saw it and said that they saw a red ghost in the middle of the night. The will-o'-the-wisp, flickering, frightening."

Gu Shao didn't take it seriously, since the last time he ate mushrooms by mistake, he no longer believed in any strange things, no

You shook your head, and happened to have read related ancient books a few days ago, and just took the opportunity to show off:

"The villagers are ignorant. The so-called will-o'-the-wisps are actually phosphorous fires. Phosphorus is the blood of soldiers and horses. Even if the ghosts are sent by heroic souls, what is there to be afraid of?"

Sun Shangxiang's immature brows tightened, and she always felt that this set of rhetoric was even more unreliable, but in terms of extensive reading, the entire government school couldn't find a single person of the same age who could compare with Gu Shao, so if you want to govern him...

She rolled her eyes, leaned forward, and poked the head in front of her with her little finger: "Ayan, did you hear that? Do you know what's going on?"

Lu Xun didn't turn his head, his eyes were fixed on the letter: "The phosphorous fire that Gu Shao said is true, but the phosphorous fire is often a yin fire with a bright color, not as hot as an open fire. According to you, it should not be a phosphorous fire."

Gu Shao thought that he was inferior to Lu Xun in everything, except that he read as much as no one could match. After hearing this, he retorted subconsciously: "What I'm talking about is all ancient records. What you said, why have I never seen it written?"

Lu Xun never quarreled with him very much, but Sun Shangxiang never gave up a chance to tease him: "Young master Gu, you read a lot, don't you know that seeing a hundred things is worth seeing once? A Yan came from Huating to Lujiang before, and watched all the way. There must be many more than you! Don’t you think, Ah Yan?”

As soon as these words came out, Gu Shao's originally resentful eyes suddenly fell silent, he frowned and shook his head slightly at Sun Shangxiang.

Huating is Lu Xun's old residence, and it is also the place where his biological father Lu Jun died. Others don't know it, but Gu Shao remembers it clearly.

That was the first time he saw Lu Xun, from his grandfather holding his hand, bringing him in front of him, putting the hands of the two children who just remembered together, and clasping them tightly.

"Remember, from now on, he will be the young master of the Lu family, your elder brother. Our two clans are closely related, and you and him are bound together for life."

That was the first time he saw Lu Xun cry.

Also the last time.

Since then, the word Huating has become a banned word in the Gu family of the Lu family. The adults kept it secret, and the little Gu Shao also learned to keep a respectful distance from this word.

It wasn't until she was a little more sensible that she realized that this new young master had a bleak life experience. Although he occasionally teased him that he was not the grandson of his grandfather, he never dared to mention his old affairs directly.

This is a secret known to everyone in the entire Lujiang City, and only the Sun family from outside can't understand the difficulties.

Sun Shangxiang didn't know the reason for this, but seeing that Gu Shao, who had always been heartless, was cautious, and didn't dare to get entangled in this matter, so he just curled his lips: "You guys

It doesn’t count what I said, I heard that Zhou Yu’s friendship is back, I went to ask Zhou Yu for advice, and what he said was absolutely right. "

Sun Quan, who had been cold for a long time, interjected with a serious face: "There are no rules."

Sun Shangxiang didn't like him: "Gu Shao called my brother's name in front of you, but I didn't see you get angry. I called Gongjin's name, why are you so anxious?"

It was rare for Sun Quan to be choked back.

Sun Ce went out with his father for many years, and he seldom rested at home. Even if he was, it was only a quick glance. On the contrary, Zhou Yu lived in Lujiang for a long time and took care of the young and old of the Sun family.

So the tall figure who rode a horse with him when he was young gradually faded away, and the word "brother" gradually became another person's exclusive appellation in the peaceful and peaceful life of Lujiang.

Of course, I can't see others belittle him.

Even if this other person is his little sister who he spoils in his daily selfishness.

A few days ago, Gu Shao was only sarcastic to Sun Quan, but he regretted it afterwards. He just wanted to find a chance to reconcile with Sun Quan. Seeing his gloomy complexion, he hesitated for a moment, and then helped him speak: "Your words are also true. No, he is your elder brother, so of course it is time to discipline you, I am not his own brother, so of course I will not attribute to him what I say."

Although he was speaking towards Sun Shangxiang, his eyes were on Sun Quan.

"Your words are too..."

Before he could utter the four words of unreasonable words, he was interrupted by Lu Xun's light cough.

Sun Shangxiang is so clever, she rolled her round eyes, looked at Gu Shao's serious face and cautious eyes, and knew that she must have offended Sun Quan, so she tentatively took the step of reconciliation.

Although she was pampered and brought up, she was not a selfish child. Knowing that the two had had quarrels, she ignored her petty temper and graciously gave her second brother a step up. Down.

She hesitated for a moment, then answered the words just now, "...that makes sense too, brother, this time it's my younger sister who is wrong, we'll go find Gongjin after school and apologize to him, okay?"

She is usually a violent chestnut who explodes when fried, and it is rare to show the delicateness of her youngest daughter. Sun Quan spoiled her in his heart, and even the coldest piece of ice melted the frost on the surface.

He frowned, looking at Gu Shao unintentionally, his face was still as cold as usual: "Of course, Gong Jin is well-read and knowledgeable, since Gu Shao and Ah Yan have a dispute, why not go to him together consult."

Gu Shao was waiting for these words, seeing him mentioning that he and Lu Xun were no different from usual, so he felt relieved

Feeling uneasy, he turned his face to the side and silently mouthed to Sun Shangxiang: "Thank you."

Lu Xun rarely looked away from the letter, and looked far away at the high and far sky outside the window.

The warm sun in April sent away the bleak wind and cold rain during the Ching Ming season, the blue sky was wiped clean by the water mist that lasted for many days, and the cotton-like clouds wiped away the last water stains, and Lujiang City returned to its former glory. sunny.

It's night, Zhou Mansion.

It was Zhou's mistress who greeted the guests, and she did not neglect the visitors because of their age.Her half-aged face can vaguely distinguish the national beauty of the past. Although the loose skin cannot retain the lost youth, the charm between the eyebrows and eyes still remains.

She touched Sun Shangxiang's cheek affectionately, her non-housework fingers were as soft as a girl's: "Just for such a trivial matter, I made a special trip to apologize to Gong Jin, you children are becoming more and more polite, it seems that Gong Jin is not in vain I hurt you."

Sun Quan has always respected Mrs. Zhou: "My brother always takes care of me, and Quan never forgets it. Why is my brother not at home when I only see my wife?"

There was a hint of helplessness in Mother Zhou's soft expression.

"I heard that there are ghosts in Nanshan, so he also went to see them."
