Chapter 334 Illustrated Book of Materia Medica

Su Song laughed loudly and refused to answer the question at all. He said, "I don't accept gifts. Why did you bring them and how did you bring them back?"

Su You put the jar on the table: "This is not for you. Do you have a tea stove?"

"Oh?" Su Song asked, "Water?"

Su You said: "From Kuizhou to Jingzhao Chang'an, it's only two thousand two hundred miles away from the same good thing."

Su Song slapped the table: "Iron gate, frozen spring water!"

Su You chuckled and said: "So we can have tea together. If you want me to give it to you, even if you are a clan brother, there is no way."

Su Song began to set up the table and set the tea sets: "Come, come, let's chat while we cook."

He took a black iron stove and added bamboo charcoal. Su Song also took a small machine, a small blower made of brass.

Shake the handle and the carbon stove will soon be on fire.

Su You looked at the small blower: "Brother Zong also has research on this?"

Su Song said: "Ah, I understand a little bit."

Su You touched his nose, I should have used these words when I was showing off.

Su Song put the water on the boil: "Are you bringing Emei snow bud or bird's tongue?"

Su You was dumbfounded and took out two bamboo tubes from his arms: "Can you smell this?"

Su Song smiled and said, "It's reasonable."

Su You began to have some admiration for this clan brother. He heard that librarians who had been born for ten years were all great. Well, maybe this one is too...

But Su Song talked about another thing: "I heard that there is also dodder in Sichuan?"

Su You said: "There are so many of these things. Wherever there are beans, there are these things."

Su Song was surprised and said: "Really? This thing has been sent as tribute from Goryeo and is expensive. Is it really available everywhere in Sichuan?"

Uh... Only then did Su You realize that he had spilled the beans. He was talking about Sichuan in later generations, and quickly made up for it: "Yes, this used to be expensive in central Sichuan, but Yujuguan's research found that it is a parasitic plant. As long as the seeds are

Sprinkle it next to beans and they will grow vigorously. So as long as you plant them properly, it's not surprising."

Su Song took out a pen and paper: "Wait, I'll write it down first."

After he finished writing, Su Song said: "It still needs to be verified."

Su You said: "It has already been proven in Sichuan, but there is no harm in proving it again in Bianjing."

Su Song added: "I heard that Kuizhou also produces cinnabar?"

Su You was a little puzzled. This brother's thinking was quite out of the ordinary: "Yes, in addition to cinnabar, there are also gold and silver."

Su Song went to the table and pulled out a book: "Here, take a look at this article. Is there anything wrong with it?"

Su You looked at it and saw that it was a paragraph of text.

"Cinnabarum grows in the Fuling Valley. Nowadays, there are Chenzhou, Yizhou, and Jiezhou, and Chenzhou is the best, so it is called cinnabar. It grows among the rock cliffs in the deep mountains, and the natives collect it. The seedlings can only be seen in the holes dozens of feet away.

, is a white stone ear, which is called a cinnabar bed. On the sand and stones, the big ones are like chicken eggs, and the small ones are like pomegranate seeds... and they are like mica flakes that can be analyzed, which is true cinnabar, and the ones without stones are better. All the people here are digging for earth and stones.

Those who get it are not born on a stone bed."

Su You said: "No problem, but it lacks many properties. This thing is a compound of mercury and sulfur..."

Su Song was shocked: "How to prove it?"

Su You said: "Because they can generate each other, the cinnabar can be reduced to metallic mercury after burning. This is a proof."

"The preparation of cinnabar is divided into wet and dry methods. The wet method is to pass a gas called hydrogen sulfide into a mercury salt solution; the dry method is to put an excess of about 20% of sulfur powder and mercury in a sealed container at a certain temperature.

Obtained by melting reaction."

"But the mercury sulfide obtained in this way is black, called black mercury, also called black cinnabar. It needs to be isolated from the air and continued to be heated to get the cinnabar you wrote about."

Su Song waved his hand: "Wait a minute, I have to write this down too. Where did you learn about this?"

Su You said: "Yu Juguan has been studying chemistry for more than ten years, and there is still a lot of progress. Uh, brother, water is enough..."

Su Songwen wrote vigorously without adding anything: "You do it, you do it, this Meishan knowledge is really remarkable now. By the way, you are an expert in steel. Read this paragraph after making tea."

Su You took the bird's tongue out of the bamboo tube and soaked it in it, then read a book. There was another paragraph of text on it.

"The iron that is first smelted and demineralized and used to cast utensils is called pig iron; the iron that is repeatedly sold and beaten to be used to make pottery is called galvanized iron, which is also called wrought iron; the iron that is mixed with raw and soft materials is used to make the edge of swords.

For steel.”

Su You nodded: "This is the method, not the essence, but it is generally correct. As for the essence..."

After finishing speaking, he pushed the booklet back: "This is a technology that even the Xixia Khitan has not yet mastered. It is a military secret and there is no comment."

Su Song smiled: "It seems that the calligraphy that Emperor Daxing left for you is really a compliment. So I feel relieved."

Damn! This can be used as a cliché. This brother is not a nerd at all!

I really don’t know where I got the temperament to sit on the bench for so long! I can only explain it with true love.

While sipping tea, the two chatted all over the place, from cuttlefish to species, from species to genetics, from genetics to breeding, from breeding to agriculture, from agriculture to water conservancy, from water conservancy to geography, from geography.

To astronomy, from astronomy to mathematics...

Neither of them could believe that there was another person so close to them in the world, and they were also relatives!

The two of them suddenly felt like confidants, and Su Song no longer kept things secret. He talked about everything he knew and even took some of his works to discuss them with Su You.

Su You had already admired this brother so much that he fell in love with him.

Why is Shen Kuo more famous than this one? That's because Shen Kuo's "Mengxi Bi Tan" can be regarded as a popular science book for the general public.

And this person’s works are basically monographs!

Therefore, in later generations, many people knew about Shen Kuo, but did not know about Su Song!

Su You couldn't sit still: "No, I met an expert and I have to show you our science and engineering stuff. I'll get it for you right now..."

Su Song smiled and pulled him to sit down: "Don't rush, don't rush, you won't finish the conversation once you look at it, and you will forget to talk about the important things."

When Su You saw the sky, it was getting dark before he knew it. He stood up and cupped his hands and said, "It's so late, so it's not good to disturb brother Zong's rest. Mingrun can come visit again tomorrow."

Su Song grabbed him and said, "Bye bye, bye bye. It's rare for me to meet someone we can talk to on weekdays. I always thought you were good at literature, but who would have thought you were a grocer! We've been talking for a whole day, and there's still nothing."

Let’s talk about the serious matters of “Illustrations and Materia Medica”…”

Su You was also embarrassed: "Actually, I came here to ask about the process of returning to Beijing to report on my work, and whether I should attend the meeting..."

After saying this, both of them felt it was funny and couldn't help laughing together.

Su Song directly greeted his old disciple and asked him to order takeout, and then went to Yiqiumen to tell his elder brother Su Xun that Run would stay with him for a few days.

It was only when he talked about this book in detail that Su You truly understood how powerful this elder brother was.

This book was edited and supplemented by Su Song when he was the director of Jixian University, together with contemporary pharmacologists Zhang Yuxi, Lin Yi and others, "Jiayou's Supplementary Notes on Materia Medica", and was revised and published as "Ji Bei Qian Jin" When I was working on "Prescriptions" and "Shen Nong's Materia Medica", I took advantage of my work and independently compiled it in my spare time!

There is one volume of table of contents and twenty volumes of content!

It is the culmination of pharmacological works of the past dynasties and the Chinese Drug Survey. It is the most complete and scientific medical book to date.

In addition to inheriting the ancient medical heritage of China for thousands of years and citing more than 200 documents, the book also supplements his own research experiences and discoveries.

In addition to text descriptions, a large number of drug graphics are also drawn, accurately recording the origin, form, properties, uses, collection seasons, refining methods, identification methods and compatibility, contraindications, etc. of various drugs. The pictures and texts are both accurate and convenient to use.

The book records more than 300 medicinal plants and more than 70 medicinal animals or their by-products, as well as a large number of important chemical substances.

This includes the preparation of salt, steel, mercury, silver, mercury compounds, aluminum compounds and other chemical substances.

There are also records of animal fossils, explanations of tidal theory, and methods for drawing plant specimens!

All of this is just the tip of the iceberg of this clan brother’s knowledge.

Ten years of sitting on the bench, not a single day in vain!

Speaking of this, Su Song was also a little proud: "I have done nothing else in the library for ten years. I just came into contact with many books and copied two thousand words that I thought were important every day and brought them back..."

After speaking, he pointed to the three walls of the study: "This is just a small part, and I didn't spend a penny."

Su You looked at a room full of information and murmured with emotion: "It seems that Sitong Company should open a bookstore in Bianjing..."
