Chapter 2006: Repenting from teaching husband-in-law and looking for a title
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 was "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. It can also be done by using a leather extractor to clean the air. The conditions for retorting are met. As for the rest, we 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. Some people 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 time 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 drive everyone out, and wrote down a summary of how to prepare nitric acid and react it 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 Xi 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 above, 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 they were making elixirs? Look carefully, you will get a white crystal powder in the end. What does it have to do with alchemy?"
Liu Shi said: "Your Majesty ordered the Tianzhu monks to refine elixirs outside Jinbiao Gate. There are also many Taoist priests in Taoist temples in Zhongnan Mountain who have refined elixirs. I have all seen them. The raw materials used are various, but there seems to be some of them. Mercury and saltpeter are also very common... Are you really not making alchemy?"
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 rot when buried." This means that it is not possible to use Chinese herbal medicine to make elixirs because they are perishable. When cinnabar is heated, it can turn into mercury and sulfur, and conversely, mercury and sulfur can synthesize cinnabar. Therefore, by taking the elixir refined from cinnabar, human life can be cycled back and forth just like cinnabar and mercury can change each other, with endless life and eternal youth.
This is why cinnabar is indispensable for making the elixir of life. Some of the elixir formulas circulated in the Han Dynasty even contained 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, the 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 offend them easily. Especially those Taoist priests who know a little bit about alchemy are regarded as talents among talents. They are almost the same as the treatment of the two-bomb and one-star heroes in later generations. Such outstanding noses cannot be offended...
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 rushed back to Lishan Farm and stayed alone in his study, recording the methods of planting corn, potatoes, sweet potatoes, peppers and other crops. Cultivation of seeds, management of seedlings, even when to plant, how to prepare ridges, how much fertilizer to apply, how much water is needed... Everything is recorded down one by one with the help of memory.
On this trip to Shuozhou, I am afraid that it will 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-yielding 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 handling matters. 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 him, and a wisp of fragrance hit his 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 Said: "It's late at night, so you should go to bed early."
Fang Jun turned to look out the window, and then he 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 still never stopped.
Holding her soft and slender waist, he picked up the beautiful concubine and placed her crosswise on his lap. He bent his head and smelled 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. It's a shame to have my wife neglect you in the boudoir."
Fang Jun said softly.
"What did Mr. Lang say?"
Xiao Shu'er 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 voice: "What girl doesn't have a heroic dream? Once upon a time , Shu'er has also imagined that she will marry an upright hero in the future. When her husband hears the chicken and dances, Shu'er will take the spoon with bare hands, just like you. When she led the army on an expedition, Shu'er sewed her armor with her own hands... Now Shu'er really married an upright hero, but 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 Son, at least you don’t have to brave the wind and snow to rush to the frontier, but fight to the death with the ferocious Hu people..."
Hot tears rolled down and wet 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 up to the green building with makeup in winter. Suddenly she saw the color of willows on the street, and she regretted teaching her husband to find a prince... It was just for her husband's sake. He was favored by the Holy Family, met Youlong kindly, and was a man of the Tang Dynasty. Now that the Hu Yi invaders are on the border, how can he stay out of it? Enjoying happiness at home, with beautiful thrushes? Fighting with iron horses and resisting foreign aggression is the true nature of our men, and the righteousness lies in it. Besides, as a husband and a commander, he should stand in the middle of the army, with warriors in robes on his left and right, so it is safe and natural. No worries, Madam, 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 willow color on the street, and she 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 woman 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 looking for 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 Shuer raised her head, with wild love in her eyes. She put her arms around Ai Lang's neck, her lips came close to hers, and murmured: "Er Lang, want me..." (End of Chapter)
