Chapter 2007: Repenting from Teaching Husband-in-law and Looking for a Marquis
How is mercury nitrate obtained?
Fang Jun didn't know, but although most of the chemistry knowledge had been returned to the chemistry teacher, it didn't mean that he didn't understand the meaning of the chemical name. Since it is "mercuric nitrate", as the name suggests, it must contain nitric acid and mercury.
Mercury is very common, and ordinary people don't know what it is, but those Taoist priests have been refining elixirs and medicines for thousands of years, so this thing is a must-have at home... As for nitric acid, he can only remember about the earliest one in the world.
Nitric acid is obtained by retorting saltpeter. Saltpeter is very common. Nowadays, there are glass containers. You can also use a leather extractor to clean the air. The conditions for retorting are met. As for the rest, you have to rely on craftsmen like Datang.
Let's go and experiment slowly.
If technology is like a tree, then as long as you grasp the trunk, you can reach the top.
However, this tree is invisible. No one can see it before grabbing it. Countless times in human history, people have grabbed this tree. But some people clung to the branches, took a side road, and entered a dead end. Others
Those who hold on to the backbone, work their way up, become sages, achieve extraordinary achievements, and are called great men.
In front of Fang Jun, a traveler, this tree is tangible and tangible. He is not a scientist, but he knows how to climb this towering tree without climbing branches or taking detours.
He found a room, ordered Liu Shi to kick everyone out, and wrote down a rough guide on how to prepare nitric acid, and then reacted nitric acid with mercury to get a white crystal. He also gave a special warning that this thing was
It is highly toxic and extremely flammable...
He handed this "recipe" to Liu Shi and ordered him to keep it strictly confidential. When recruiting craftsmen to prepare it, it must be made in batches and no leakage is allowed.
Liu Shi wiped the sweat from his palms and took the pieces of paper gingerly, feeling heavy in his heart.
This was a very heavy trust, but he was not very happy, because looking at Fang Jun's solemn look, he knew that once he leaked this "secret recipe", with Fang Jun's temperament, even the emperor
You can't protect yourself unless you change your name and wander around the world...
As the next head of the Liu family in Hedong, is he willing to give up his family fortune for a secret recipe?
The answer is naturally no, so even if he dies, he must not reveal this secret recipe.
After just glancing at the words on it, especially the words saltpeter, mercury, etc., I was a little confused. Qiqi Aiai asked: "Master Hou, what kind of elixir is this...refined?"
"What kind of elixir is being made?" Fang Jun was also confused: "Who said refining an elixir? Look carefully, you will get a white crystal powder in the end. What does it have to do with elixir refining?"
Liu Shi said: "Your Majesty ordered the monks from Tianzhu to refine elixirs outside Jinbiao Gate. There are also many Taoist priests in Taoist temples in Zhongnan Mountain who refine elixirs. I have seen them before. The raw materials used are various, but they seem to have some.
Things like mercury and saltpeter are also very common... Are you really not making elixirs?"
The art of alchemy has been popular in ancient and modern times.
Although the raw materials for alchemy are ever-changing, they also have certain rules. For example, herbs and herbs "will rot when boiled and will rot when buried." For example, "cinnabar is burned into mercury and accumulated and transformed into cinnabar." That is to say, using
It is not possible to make elixirs from Chinese herbal medicines because they are prone to decay. When cinnabar is heated, it can turn into mercury and sulfur. In turn, mercury and sulfur can synthesize cinnabar. Therefore, taking elixirs refined from cinnabar can make people's lives just like cinnabar and mercury.
Like the mutual transformation, it can be cycled back and forth, endlessly reborn, and eternal youth.
This is the reason why cinnabar is indispensable for making the elixir of life. Even some elixir formulas circulated in the Han Dynasty included cinnabar, saltpeter, sulfur and other raw materials.
That's right, it's infinitely close to gunpowder...
Fang Jun said angrily: "Refining a damn pill!"
Although arsenic can also be used as medicine, and there are many prescriptions in Chinese medicine to fight poison with poison, but if you take cinnabar, mercury, and saltpeter all year round, do you still want to live forever?
It's too slow to die!
If nothing else, if you eat a few bags of preservatives in food packaging bags, how will you react?
The original main ingredient of that thing was saltpeter. Later, chemical preparations were invented, which were even more poisonous...
But then I thought about it, Taoist priests in this era are the best chemists. Can we get a few Taoist priests to study mercury nitrate?
He immediately gave up the idea.
Today's Taoist priests are amazing. The Li and Tang royal families respect Lao Tzu as their ancestor and admire Taoism. Taoist priests have their own halo, and no one dares to mess with them. Especially those Taoist priests who know a little bit about alchemy are regarded as talents among talents. It is simply
It’s no different from the treatment given to the two-bomb and one-star heroes in later generations. I can’t afford to offend someone with such a cool nose...
The progress of science and technology cannot be achieved overnight. It must be done step by step and steadily. Perhaps there will be unexpected gains in the process of developing mercury nitrate.
*****
In the evening, Fang Jun hurried back to Lishan Farm and stayed alone in the study, recording the methods of planting corn, potatoes, sweet potatoes, peppers and other crops. The cultivation of seeds, the management of seedlings, and even when to plant and how to prepare.
Ridges, how much fertilizer should be applied, how much water is needed... everything is recorded in detail, one by one based on memory.
This trip to Shuozhou may be difficult to return in a short time. The Xueyantuo people dared to brave the heavy snow and press the border uncharacteristically. Their ambitions are definitely not small. I am afraid that their intention is not only to force the Tang Dynasty to make a marriage, but also whether there is a shadow of Goguryeo in it.
, also unknown.
The season waits for no one, and this batch of seeds is of great significance. It must be allowed to grow vigorously before enough seeds can be bred for large-scale cultivation. In three to five years, it will be ensured that most of the land in Datang can be planted with high-yield corn and sweet potatoes.
,Potato.
These must be arranged before leaving.
In fact, if it weren't for His Majesty Li Er's imperial edict, Fang Jun would rather give up all his achievements and cling to these seeds and the hope that they will feed countless Han people...
Fortunately, although the bureaucrats in Sinong Temple are of low standard, they are not not doing their jobs. Sinong Qing Yin Yue does not understand farming technology at all, but he is placed in a right position and treats the technical officials in the yamen very favorably.
Pay attention to these seeds cultivated in the Lishan greenhouse.
Although the agricultural officials of the Tang Dynasty had limited knowledge due to the era, they were all diligent and good at their job. As long as Fang Jun arranged properly, no link was missed, and precautions were taken to deal with situations in advance, there would probably be no problems.
There was a soft sound of footsteps beside me, and a wisp of fragrance hit my nostrils.
Fang Jun looked up and saw Xiao Shu'er coming in quietly, holding a tea cup in her hand. Seeing Fang Jun who was awakened from thinking, he showed a sweet smile, stepped forward and put the tea cup on the table, saying softly
He said: "It's late at night, so you should go to bed early."
Fang Jun turned to look out the window and realized that it was completely dark, but the lantern hanging outside the window was swaying in the wind. The dim light illuminated the night sky, and the snowflakes never stopped.
Holding her soft and slender waist, she lifted the beautiful concubine and placed her crosswise on his lap. He bent his head and sniffed the crystal white neck, and a scent like orchid and musk penetrated his nose.
"You are newly married, and you are about to lead an army on an expedition. However, it is wrong for you to have your wife neglected in your boudoir."
Fang Jun said softly.
"What did Mr. Lang say?"
Xiao Shuer snuggled her head in Fang Jun's arms, pressed her face against his broad chest, listened to the strong heartbeat, wrapped her arms around his thick waist, and said in a soft and soft voice: "What girl doesn't have a heroic dream? Once upon a time , Shu'er also imagined that in the future, she would marry an indomitable hero. When her husband heard the chicken dance, Shu'er would take a spoon with her bare hands. If you led the army on an expedition, Shu'er would sew her armor with her own hands... Now Shu'er has really married an indomitable hero. But she found that her previous fantasies were wrong. Shu'er would rather her husband was just a playboy who accomplished nothing in fighting cocks and walking dogs. That way, at least he wouldn't have to brave the wind and snow to go to the frontier and fight to the death with the ferocious Huren..."
Hot tears rolled down and wetted the clothes on Fang Jun's chest.
Fang Jun held the soft and delicate body in his arms and said with a chuckle: "The young woman in the boudoir has no worries. She goes to the green building with makeup in winter. Suddenly she sees the color of willows on the street. She regrets teaching her husband to find a prince... It's just for her husband's sake. I am a man of the Holy Family, I met Youlong, and I am a man of the Tang Dynasty. Now I am surrounded by barbarians. How can I stay out of it, enjoy happiness at home, and have beautiful eyebrows? Fighting against foreign aggression is the true nature and righteousness of our men. That's where you are. Besides, as a husband and a commander in chief, he should stand in the middle of the army. There are warriors on his left and right, so he will be safe. My wife, you can rest assured."
"The young woman in her boudoir knows no worries, and goes up to the green building with makeup in winter. Suddenly she sees the color of willows on the street, and regrets teaching her husband to find a prince..."
Xiao Shuer murmured this poem in her mouth, as if a picture was unfolding in front of her eyes. A young lady in the boudoir who was young and in good condition always dreamed of marrying a great hero. When her husband went away to fight in the winter, she walked alone on the embroidery journey. Building, I suddenly found that there were faintly green willows at the end of the path in the yard, but my husband who went on an expedition still had not returned...
Lonely and miserable, regretful and longing.
I regret teaching my husband and son-in-law to seek a title...
What kind of man is this? He has both the heroic masculinity of a man and delicate and sad words. How many blessings have he cultivated in his previous life, so that he can be by your side in this life?
Xiao Shu'er raised her head, with wild love in her eyes. She put her arms around Ai Lang's neck, put her lips close to hers, and murmured: "Er Lang, want me..."
