Tiantang Splendid

chapter 2006

How is mercury nitrate obtained?
Fang Jun didn't know, but although most of his chemistry knowledge had been returned to his chemistry teacher, it didn't mean he didn't understand the meaning of the chemical name. Since it was "mercury 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 alchemy for thousands of years, and this thing is a must-have thing at home... As for nitric acid, he can only remember the earliest Nitric acid is obtained by dry distillation of saltpeter. Saltpeter is very common. Now there are glass containers, and it can be done with a leather pump to clean the air. The conditions for dry distillation are met. As for the rest, we have to rely on craftsmen like Datang We went to experiment slowly.

If technology is a tree, as long as we grasp the trunk, we can reach the peak all the way.

However, this tree is invisible, and no one can see it before grasping it. In the history of mankind, people have grasped this tree countless times, but some people clung to the branches, took a fork in the road, entered a dead end, and some Others have grasped the backbone, all the way up, become sages, achieved extraordinary achievements, and are called great men.

In front of Fang Jun, a time traveler, this tree is really visible and tangible. He is not a scientist, but he knows how to climb this towering tree without climbing branches or going astray.

He found a room, ordered Liu Shi to drive everyone out, and wrote down how to make nitric acid, and then use nitric acid to react with mercury, and a white crystal would be obtained, with a special warning that this thing is It is highly poisonous and extremely flammable...

Give this "recipe" to Liu Shi, and order him to keep it strictly confidential. When recruiting craftsmen to prepare it, they must be divided into batches and no leaks are allowed.

Liu Xun wiped the sweat from his palms, and took the papers over tremblingly, feeling heavy in his heart.

This is a very heavy trust, but he is not very happy, because looking at Fang Jun's solemn expression, he knows that once he leaks this "secret recipe", with Fang Jun's temper, he will be regarded as the emperor. I can't keep myself, unless I change my name and surname and wander around the world...

As the next patriarch of the Hedong Liu family, is he willing to give up his family business for a secret recipe?

The answer is naturally no, so even if he dies, he must not reveal this secret recipe.

Just glanced at the words above, especially those words such as saltpeter, mercury, etc., and was a little confused, Qi Qi Ai asked: "Master Hou, what kind of pill is this...refined?"

"What kind of alchemy?" Fang Jun was also at a loss: "Who said alchemy? Take a closer look. What does it have to do with alchemy if you want to get a white crystal powder in the end?"

Liu Xun said: "Your Majesty ordered the monks from Tianzhu to concoct alchemy outside Jin Biao's Gate. There are also many Taoist priests in Zhongnan Mountain who concocted alchemy. The officials have all seen it. The raw materials used are various, but there seem to be some of them. Mercury and saltpeter are also very common... Are you really 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, such as the medicine of plants and trees, "it will rot when boiled, and it will rot when buried", for example, "cinnabar is burnt into mercury, and accumulated and transformed into cinnabar".That is to say, it is not acceptable to use Chinese herbal medicines to make alchemy, because they are perishable.And cinnabar can be turned into mercury and sulfur after heating, and in turn, mercury and sulfur can synthesize cinnabar.Therefore, taking the elixir made of cinnabar, one's life can be cycled back and forth, just like the transformation between cinnabar and mercury, and the life is endless and youthful.

This is the reason why cinnabar is inseparable from refining the elixir of life. Even some elixir formulas handed down in the Han Dynasty contained cinnabar, saltpeter, sulfur and other raw materials.

That's right, it's infinitely close to gunpowder...

Fang Jun said angrily: "Pan that made a fart!"

Although arsenic can also be used as medicine, there are many prescriptions in traditional Chinese medicine that use poison to fight poison, but taking cinnabar, mercury, and saltpeter all year round, do you still want to live forever?
Too slow to die!
Not to mention anything else, the preservatives in food packaging bags are okay to eat a few bags, and see what your reaction is?
The original main ingredient of that thing was saltpeter, and later a chemical agent was invented, which was even more poisonous...

But after thinking about it, the Taoist priests of this era are the best chemists. Can you get some Taoist priests to study mercury nitrate?

Immediately dismissed the idea.

Today's Taoist priests are great. The royal family of Li and Tang respected Lao Tzu as their ancestors and admired Taoism.Especially those Taoist priests who know a little about alchemy are regarded as talents among talents, and they are treated no differently from the treatment of the two bombs and one star heroes in later generations.

The progress of science and technology cannot be achieved overnight, but should be done step by step, and there may be unexpected gains in the process of research and development of mercury nitrate.

*****
In the evening, Fang Jun rushed back to Lishan Farm and stayed alone in the study, recording the planting methods of corn, potatoes, sweet potatoes, peppers and other crops.The cultivation of seeds, the management of seedlings, even when to plant them, how to prepare ridges, how much fertilizer to apply, how much water is needed... everything is detailed, and they are recorded one by one with the help of memory.

This trip to Shuozhou, I am afraid it will be difficult to return in a short time. The people of Xue Yantuo dared to brave the heavy snow to press the border uncharacteristically. The ambition is definitely not small. I am afraid that the plan is not only as simple as forcing the Tang Dynasty to marry, but whether there is a shadow of Goguryeo , is also unknown.

The seasons wait for no one. This batch of seeds is of great significance. It must be grown vigorously to produce enough seeds for large-scale cultivation. After 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.

Before leaving, these must be arranged.

In fact, if it wasn't for His Majesty Li Er's imperial decree, Fang Jun would rather give up all his meritorious deeds, and stick to these seeds, and hold on to these hopes that will feed countless Han people...

Fortunately, although the bureaucrats in Sinong Temple are of low level, they are not not doing business. Yin Yue, Secretary of Agriculture, does not understand farming techniques at all, but he is placed in the right position, giving preferential treatment to the technical officials in the yamen Pay attention to these seeds cultivated in the Lishan greenhouse.

Although Datang's agricultural officials had limited knowledge of the times, they were all diligent and conscientious. As long as Fang Jun arranged properly, every link was not missed, and how to prevent and deal with situations in advance, there would probably not be any problems.

There were soft footsteps beside her, and a faint fragrance wafted into her nostrils.

Fang Jun raised his head, and saw Xiao Shu'er coming in lightly, holding a teacup in his hand, and seeing Fang Jun who woke up thinking, he showed a sweet smile, stepped forward to put the teacup on the table, and said softly Said: "It's late at night, you should go to bed earlier."

Fang Jun turned his head and looked out the window, only to realize that the sky 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 did not stop.

Embracing the soft and slender waist, she picked up the concubine and laid it horizontally on her lap, bowed her head and took a sniff between the crystal white neck, a scent like orchid and musk penetrated into her nostrils.

"As a newlywed, you are going to lead an army to go to war, but you have been wronged by telling the lady to leave her boudoir in the cold."

Fang Jun said softly.

"What did you say, Mr. Lang?"

Xiao Shu'er nestled her head in Fang Jun's arms, her face pressed against his broad chest, listening to the powerful heartbeat, her arms wrapped around her thick waist, and she said softly, "Which girl doesn't have a heroic dream? Once upon a time Shu'er also imagined that she would marry an upright hero in the future, and when her husband heard the chicken dancing, Shu'er would just use a spoon, and if the king led an army, Shu'er would sew armor with her own hands... Now that Shu'er really married an upright hero, But she found that her previous fantasies were all wrong, Shu'er would rather her husband is just a dude who can't do anything by fighting cocks and walking dogs, that way, at least she doesn't have to brave the wind and snow to go to the frontier, but fight to the death with the ferocious barbarian..."

Hot tears rolled down, wet the skirt of Fang Jun's chest.

Fang Jun embraced his gentle and delicate body in his arms, and said with a light smile, "Young women in the boudoir don't know how to worry, and go to the Emerald Building with makeup on in winter. Suddenly seeing the color of willows on the street, I regret teaching my husband and son-in-law to seek a title...just for my husband's body Bearing the holy family, being kind to Youlong, and a man of the Tang Dynasty, how can he stay out of the sidelines of the Hu barbarians now, enjoy the joy at home, and embrace the beautiful thrush? Gold and iron horses, resisting foreign aggression are the true qualities of our generation of men, righteousness The location is also. Besides, as a husband and commander in chief, he should stand in the middle of the army, and there are warriors in robes on the left and right, so he is safe and sound, and the lady can rest assured."

"The young woman in the boudoir doesn't know how to worry. She puts on her makeup and goes to the emerald building in winter. Suddenly she sees the color of willows on the street, and regrets teaching her husband and son-in-law to seek a title..."

Xiao Shu'er murmured this poem, as if a picture scroll appeared in front of her eyes, a young woman in the boudoir always dreamed of marrying a great hero, and when her husband went out to fight in winter, he walked alone on the embroidery field. Suddenly, there was a willow green at the end of the path in the yard, but the husband who went to the expedition still hadn't returned...

Lonely and desolate, regretting and missing.

Regretful teaching husband-in-law looking for a Marquis...

What kind of a man is this? He has both masculinity and masculinity, but also has delicate and euphemistic words. How many blessings he cultivated in his previous life, can he be able to accompany you in this life?
Xiao Shu'er raised her head, her eyes were full of love, she wrapped her arms around Ailang's neck, her fragrant lips moved together, and she murmured: "Erlang, take me..."
