Yang Su asked in a low voice: Does the lead red really have a miraculous effect?

Wang Yuanzhi felt a chill, and only said four words: filth.

Listen to Zhao Jingzhi again: This matter is very important, and Huoyuntang does not dare to make his own opinions. Just spying on them, they not only arrested young girls, but also children under the age of one. I heard that the dragon and phoenix pills that were recently dedicated to the emperor are all made from the bone marrow of young girls and young children.

Wang Yuanzhi said angrily: "It's extremely hateful! If you kill and kill people and get immortality, what is the reason of heaven!

Who knew that at this juncture, Yang Su asked in a low voice: Is it really useless to tonify the Dragon Dan Phoenix Pill?

Wang Yuanzhi held back his anger and replied: Entering the abdomen and dissolving feces is no different from cow marrow and pig marrow!

Yang Suruo lost his way: There is no need to talk about anything else, it is so hurtful, killing him 10,000 times is enough.

In fact, what Yang Su hated the most was that many magistrates bought Pan Wei and spoke in front of the emperor. Yang Su cut off Pan Sao's wings in many ways, and eight or nine out of ten of them have been removed. Of course, Pan Yi will not sit idly by, and spread rumors in many ways, saying that Yang Su wants to rebel!

In the end, Yang Su ended breakfast with six words: Demon removal Dao, Qingjun side!

Next, the major events of the Qingyun Gang were reported by the hall masters. They are wind forest volcanoes, autumn water and long days, flying clouds and cranes. A total of 12 churches. When talking about Feiyun Hall, Ziyi and Tsing Yi looked at each other. Tsing Yi stood up and talked about the big things in the hall, such as how many small gangs were accepted and the business situation in Kansai. The recent conflict with the Lee clan in the state of Merge is also mentioned.

Yang Sudao: Li Yuan already knew that Feiyuntang was the old man's person. He will never be in trouble with you. Presumably it's really ignorance.

As he spoke, he changed his mind: Li Yuan has some skills, and this time he will be on the road. Don't touch him yet, let him guard and annex the state, resist the Turks, and there will be a lot less trouble.

Tsing Yi Dao: But the disciples are worried that Li Yuan is sitting big, his sons are all shrewd and capable, and the shogunate has been opened, and talents from all over the world are competing to go there......

Yang Su was silent, and said in his heart: The old man still has a few years to live, ten or twenty years later...... Let's see first!

Since the snow valley, it can be said that there is no day of leisure. At this moment, I am in the Mansion of Chu State, accompanied by beautiful women, and my lover is with me. Wang Yuanzhi was relaxed, and he really lived a few days of leisure. Li Jing and Yang Hongyi (real name Zhang Chuchen) also had news, and the two went to Chang'an County to take office. Ask someone to bring a letter of humility. Yang Su threw it away without looking at it. As long as the old man lives, you don't want to be promoted in your life!

The news that the Dao Sect was about to enter Beijing had been issued, and the Daomen of the world were shaken. rushed to the eastern capital, Pan Yi was really angry. It's a pity that time is pressing, but I'm afraid that most of them won't be able to make it. Who made the Taoist priests always love to live in the mountains, and they received the news too late, and some of them didn't know yet.

Yang Su asked Wang Yuanzhi for a plan for this matter, and Wang Yuanzhi looked confident. I don't take Pan Yi in my eyes. Yang Su knew that the monks were grotesque, and he was not surprised. But it is better to prepare in advance in the DPRK, just in case. In fact, Wang Yuanzhi also made some preparations for the Huashan faction and the beggar gang, and the other preparations were the production of big killing weapons and powerful magic weapons.

Opening a Dan house in Yang's Mansion is just a gesture, and Yang Su directly divided two into the courtyard, and he can do whatever he wants. After the Danfang is built, the first step is, of course, the fire dragon scatter. With the fire dragon scattered, there is a scattered wealth boy and a scattered flower fairy. Now everyone knows that one nitrate, two sulfon, three wood charcoal. Can you make fire with this word? Everyone has it except charcoal. What is nitrate, where does it come from, what is sulfur, and where does it come from? I'm afraid few people know. Don't go to the chemical store to buy it.

Sulphur is easier to find, as many hot springs produce natural sulphur. It has been mined in ancient times. Saltpeter is also natural, but it is mainly artificially made. Before the liberation, the transportation was inconvenient, and most of the poor people in Weihui, Henan Province, their hometown, ate "small salt", which tasted bitter. It's really people who don't understand, it's "nitrate".

Ziyang Zhenren opened the sermon:

Methods of making * from nitrate:

【Principle】*Commonly known as fire nitrate or earth nitrate. It is an important raw material for black fire yao and compound chemical fertilizers. * Nitrate soil and plant ash can be used as raw materials. After the organic matter in the soil decays, nitric acid is formed by the action of nitrite bacteria and nitric acid bacteria. Nitrate combines with potassium, sodium, magnesium and other ions in the soil to form nitrate. That's how the nitrates in nitrate come from. Nitrate soil is generally found in toilets, pig and cattle pen houses, old walls in courtyards, cliff edges, caves, and ground that is not easily washed by rainwater. The nitrate soil is moist, not easy to dry, and turns slightly purple-red after being exposed to the sun. A good nitrate will spark when placed on red-hot charcoal.

The main principle of extracting * from nitrate is to use potassium ions in plant ash to replace sodium ions in nitrate soil, so as to generate*. In addition, the carbonate ions and sulfate ions in the plant ash combine with the calcium and magnesium ions in the nitrate to form insoluble salts and precipitate, thereby removing impurities such as calcium and magnesium. The main reaction formula is:

Ca(NO3)2+K2SO4=2KNO3+CaSO4↓

Ca(NO3)2+K2CO3=2KNO3+CaCO3↓

Mg(NO3)2+K2CO3=2KNO3+MgCO3↓

Li Yuanba: Damn, it's really crossing!

Ziyang Zhenren wept and said: "Apprentice, being a teacher is also involuntarily! When you grow up, don't offend the author, that is the work of the creator god."

Li Yuanba: Hehe, I'm happy to slaughter the gods!

Ziyang Zhenren: There is a kind!

Author: Don't bother, Ziyang made a frame and held the whip, Li Yuanba put his hands on his cheeks, Yuan Tiangang opened the notebook, Li Chunfeng stretched his stinky feet to the podium, and occasionally continued to read the text. Lights are ready to shoot!

Reader: Is there any mistake! Lao Tzu went here for chemistry class!!!!!!

The creator God said: Protest is invalid!

The nitrate itself also contains *, and finally the difference in the solubility of various salts is used to control the temperature and concentration to crystallize * from the mixture.

[Operation]

(1) Grind the nitrate soil and plant ash separately and crush them. Weigh the raw materials according to the mass ratio of 8:1 of nitrate and plant ash (the ratio of raw materials varies due to different sources), mix and put in a large beaker, and add hot water at about 75 °C until the mixture is immersed.

(2) Stir continuously with a glass rod for about 15 minutes, and then carry out suction filtration. The slag is placed in a beaker again, an appropriate amount of hot water is added and stirred for 15 minutes, and the filtrate is filtered again, and the filtrate of the two times is combined together (when there are more raw materials, it can also be filtered only once), and the filtrate obtained is often called nitrate.

(3) Pour the nitrate water into a large evaporation dish, heat and evaporate (this step is called boiling nitrate), and stir constantly when heating to prevent sticking to the bottom and splashing.

(4) Stop heating when 2/3~3/4 volume of water is evaporated. At this time, the solution is viscous, and a small amount of solids have been precipitated from the bottom of the evaporation dish. Take a drop of solution with a glass rod and drop it on the paper, if the solution immediately condenses into a clump, it means that the requirements have been met, and immediately filter while hot. At this time, the temperature is very high, and the solubility of * is large and will not precipitate, while sodium chloride, potassium chloride, etc. will precipitate due to the low solubility.

(5) Let the filtrate naturally cool to 30 °C, at this time, the solubility of * is affected by the temperature and changes the most, and the solubility drops sharply and a large amount is precipitated. The solubility of salts such as sodium chloride changes little and basically no longer precipitates. Filtration is repeated to obtain * crystals. If further purification is to be desired, it can be recrystallized.

【Description】

(1) The ash obtained from the burning of buckwheat stalks, cotton husks, cotton stalks, broad bean stalks, rapeseed stalks, tomato stalks, sorghum stalks, corn stalks and other plants is the best, and their potassium content can reach 10~15%. Of course, other plant ashes can also be used.

(2) The above principles are also applicable to the production of soil nitrate by soil method.

Taoist priests have been engaged in physical chemistry for thousands of years in the era of Wang Yuanzhi. Legend has it that the Yellow Emperor did this. As with Chinese medicine, the method is correct, the effect is obvious, the results are great, the theory is wrong, the development is slow, and the future is no. It's all the accumulation of experience from generation to generation.

Wang Yuanzhizai carefully passed on the craft of making nitrate to the three apprentices, and asked them to swear a heavy oath that the formula of Huolongsan could not be given even to their own father, this is the magic weapon of the Daomen to eat mixed rice! With three free laborers, Wang Yuanzhi is like a beast in a prestigious university. The results are coming out. I really have medicine in my hands, and I don't panic. In two days, hundreds of catties of fire were made. What kind of bullshit great master, Lao Tzu will kill you! When you take out the stone essence, you have to sprinkle it all on yourself.

Under the full supervision of the teacher, the three apprentices each made a small cannon. Fill the medicine with the thinnest bamboo, light the sandalwood and run. Boom, boom, the three cannon charges are different, and the sound is different. The three of Yuanba, Tiangang, and Chunfeng were excited. This is the Dao Technique! The real Dao Technique! With this, the rivers and lakes go sideways. In fact, not to mention the rivers and lakes, thousands of troops and horses are walking sideways, which is the secret of Li Yuanba's fame.

The four masters and apprentices were happy here, except for the purple-clothed sleeping baby in the entire Yang Mansion, and the others, including Yang Su, might be frightened. Ziyang Zhenren Niu B coaxed: Immeasurable Tianzun, just poor Taoist children have a little spell, don't make a fuss.

Blindfold a group of people like big-headed mosquitoes.

After finishing the fire yao, it's time to refine some serious things. The purple bamboo salt that promised the purple clothes has not been found. At this time, the Dan furnace was started, and there were helpers, so the project was launched.

Cut the bamboo into sections and pour sun-dried salt into the bamboo tube. The fuel for calcining bamboo tubes is pine wood, and the kiln used for calcining must be made of loess——— only then the calcined bamboo salt can appear purple.

Just this earthen kiln, it is hard to make nine dragons outside the name of the Nine Dragons Ding! Ziyang Zhenren taught the three migratory brothers: Appearance is very important, and it is the first element of B. If you pretend to be B, you will give birth to B. Don't say it's really B. This is what later generations called packaging.

Loading B wasted a day, and the fire was fired early the next morning!

About five hours later, the first calcined bamboo salt came out. When the bamboo is burned, the water seeps into the salt, and the salt becomes a salt stick. Yuan Tiangang saw it and sighed: It's so rough!

Ziyang Zhenren scolded: Nonsense! Next time you use a thin bamboo, you don't have to feel inferior.

The bamboo salt that has been calcined for the first time is crushed and then burned in the bamboo. This process is repeated 8 times, and by the 9th time, the pine resin is sprinkled into the fire and the temperature is adjusted to the highest limit, at which point the solid salt becomes liquid.

After 9 times of calcination, the bamboo salt will perform its best effect. No more, no less, it must be 9 times. Only after calcination at 1350°C to 1500°C will it turn into a bamboo salt ———purple bamboo salt.

In fact, our ancestors had a strong interest in roasting salt a long time ago.

The ancient medical books "Shennong's Materia Medica" and "Compendium of Materia Medica" have discussed roasted salt.

As early as 5,000 years ago, before medicine was developed, our ancestors used to stir-fry salt, or roast it in a bamboo tube several times, and use it as a digestive agent when they were stagnant or indigestible in the future. It is used as a hemostatic or anti-inflammatory agent when injured, and it is also used instead of toothpaste for brushing teeth, as an eye drop for eye wash, and so on.

Three days and three nights, three apprentices and three class guides, finally succeeded in the first furnace, a total of 200 catties of bamboo salt. Yang Su also finally ruled the secret. Calculate the time, tomorrow is the Shangyuan Festival, Yang Mansion began to live, not to make a Lantern Festival, but to the eastern capital Luoyang to smash the field!
