The next day, in the palace, Yuwen Wen slept until noon before getting up, yesterday's experience was too exciting, consuming a lot of his energy, so it was rare to sleep lazy, of course, in order to avoid extraneous branches, the things that should be done have been arranged in advance. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

First of all, he has to 'report safety' to the palace and the Prime Minister's Mansion, the movement he made in the prison of the Qiuguan Mansion is not small, it is impossible for the Prime Minister Chi Yu not to know, and the little emperor in the palace must know sooner or later, so he has to take the initiative to avoid unnecessary misunderstandings.

Then there was the arrangement for someone to investigate the mastermind behind the scenes, and he was almost privately proposed to be tortured in the cell, so a group of jailers needed to go to 'greet', and all those involved had to be caught in the net.

Then it is to place the alchemy master and apprentice, that Liu Yang Dao accidentally caused a big explosion when he was alchemy, in order to avoid someone with a heart from probing the secret, it is said that he has to take care of it, which was originally Yu Wenwen's father-in-law Wei Chi Shun was responsible, but Yu Wenwen had an 'adventure', so he volunteered to take this job.

Liu Yang tossed out the alchemy technique, and then accidentally came up with the spectroscopy, although this spectroscopy is very primitive, it may be barely qualitative (to determine whether there is a certain metal in the sample), and it is unlikely to be quantified (how much content), but it is also commendable.

This kind of strange character Yuwen Wen will not let go, he not only has to guard it strictly, but also 'pack' the other party back to Bazhou.

was eating lunch, Zhang Yu entered, he saw that Yuwen Wen was still eating lunch, hesitated for a moment before saying that Liu Daochang was outside to ask to see, and he had been waiting outside the hospital since the morning, asking from time to time, "Is Yuwen Langjun free?"

"Let him in."

"Yes."

Zhang Yu exited the room, Yu Wenwen couldn't help but shake his head when he remembered yesterday's scene, when Liu Daochang hugged his leg and cried "Lang Jun, I want to learn chemistry", and at that moment he remembered another classic line: "Coach, I want to play basketball." ”

Since you sincerely want to learn, then I will teach it reluctantly, and God knows what results you will achieve.

Footsteps sounded, from far to near, and then the door was pushed open, and Liu Yang, who was wearing clean clothes, ran in, and saw that Yuwenwen was eating after the dining table, so he slowed down and sat down: "Lang Jun, can you start now?" ”

The master didn't let him sit down, so he sat down directly, and it was really unrestrained. Yu Wenwen was a little helpless, this Liu Daochang really didn't understand much about the world, similar to a nerd who was not good at communicating with people when he read books.

Seeing the other party's expression full of expectation, Yu Wenwen was not in a hurry, he asked questions while eating, first asking Liu Yang and his apprentice how they ate, lived and dressed in the embassy last night, and then asked if they had lunch today, and after making sure that everything was normal, he turned to the topic.

This alchemist, who has been 'in the industry' for more than 30 years, wants to learn chemistry, and the first thing to bear the brunt of is those erroneous knowledge, just like writing something on a piece of paper full of words, it is impossible, so he wants to let the other party's head 'empty' and leave those inexplicable alchemy knowledge behind.

If you want to have a good effect, you must drink it as a stick, so Yu Wenwen decided to 'lure the snake out of the hole' and let Liu Yang introduce the principle of alchemy, and then he 'hit seven inches' again, directly hit the key point, and refute the most basic alchemy theory one by one.

Speaking of alchemy, Liu Yang is still full of energy, although he has learned that there is a magic method of 'chemistry', but after all, he has been refining the pill for decades, and the 'feeling' does not mean that there is no one.

Listening to Liu Yang's eloquent talk, Yu Wenwen didn't understand the various terms in it at all, he nodded and pretended to be listening, while thinking about the core idea of the alchemy experience.

The alchemists of the Central Plains pursued the elixir of immortal energy, and then became immortal after taking it, because of immortality, they were obsessed with gold that had not decayed for thousands of years, and the longing for immortals led alchemy astray.

Alchemists believe that immortals are complete with heaven and earth, and with the sun and moon; Sit and see thousands of miles, and serve ghosts and gods; The whole family rises to the void, flies without wings, rides the clouds and drives the dragon, the top and bottom are too clear, between the missing moments, and travels around the eight poles.

In other words, the biggest characteristic of immortals is that they fly and travel in the void, so people always associate immortality with feather ascension.

Therefore, those substances that are easy to fly when they see fire and are lightened (easy to sublimate) are a kind of supernatural things in the eyes of alchemists.

According to this theory, in addition to gold, alchemists like dansha and mercury the most, which is a panacea in their minds, because "dansha burns into mercury, and accumulates and changes into dansha".

Dansha and mercury are converted to each other, "fine and ruddy, the longer the accumulation, the more wonderful the change, can fly energy powder, can refine snow, can resist fire, can turn water, can sell it without consumption, buried it can not be bad", it is really wonderful.

Then there are various appearances, such as after eating dansha, "the fog is dispersed like a storm, and the fumigation reaches the limbs", and some people say that "the mud pill is overflowing, the dantian is abundant, the three gods are happy, and the clouds are like a dream".

As soon as he thought of the elixir with a serious mercury content exceeding the standard, he just ate it in his stomach, Yu Wenwen couldn't help but feel chills all over his body, he looked at Liu Yang, and saw that it happened to be an 'intermission', so he began to 'fight back'.

"I wonder if the Venerable Master is taking the pill he has refined?"

"This is natural, the ancestor has been alchemy for decades, so it is natural to take the pill."

"Well, I have a question, of course, I don't mean to disrespect the teacher." Yu Wenwen was considering the choice of words, he and Liu Daochang used the self-proclaimed 'I' in the conversation, Yu Wenwen felt that this seemed to be a little 'stupid and cute', but he didn't know what his feelings for the master were, in order to avoid irritating the other party, he specially stated it before asking questions.

Seeing that Liu Yang nodded to indicate that it was okay, Yuwen Wen coughed dryly and asked, "Before the Venerable Master drove the crane west, was he extremely excited, or moody and irritable?" ”

"Well, there are some."

"Did Venerable Master tremble in his limbs, couldn't hold chopsticks steadily, his clothes and walking were affected, and even his speech pronunciation was a little strange?"

"Yes, the ancestor was no longer able to dress himself at that time, and his daily life was taken care of by the poor."

"So, in the mouth of the Venerable Master, in the mucosa under the gingivals, is there a short blue-black line?"

"How did Lang Jun know?" Liu Yang was quite surprised when he heard this, the symptoms that Yu Wenwen said were the same as those of his master before his death, "When he was driving the crane, Poor Dao fed the ancestor with a decoction, but his teeth were closed and could not be opened, and at that time, Poor Dao saw that a short blue-black line appeared in the mucosa under the gums. ”

Yuwenwen wanted to get away with it, and asked Liu Yang if he wanted to know how he guessed this symptom, Liu Yang naturally asked why, and Yuwenwen then said the answer: This is a typical symptom of chronic mercury poisoning.

Dansha, according to the chemical term, is mercury sulfide, when heated, the reduction reaction occurs, sulfur and mercury are separated, and the sulfur disappears into a gaseous state, leaving a silvery-white liquid mercury, so the elixir refined from dansha has a high mercury content.

Lao Liu Daochang has been taking this pill for a long time, so he gradually became mercury poisoning, and when he became seriously ill in the later stage, he would have the above symptoms.

"It's... It's impossible! Liu Yang had an expression of disbelief.

"It's mercury poisoning, mercury enters the human body, it can't be eliminated, it accumulates more and more over time, it will cause people's nervous confusion, and the place of convergence is near the gums, so there will be blue-black short lines!" Yuwen Wen said categorically, his tone was unquestionable.

Liu Yang was dumbfounded when he heard this, he wanted to say something but couldn't say anything, since he came into contact with alchemy, the master taught Chunchun how the dansha is rich in immortal energy, and how wonderful its effect is.

Now Yu Wenwen said that this was poison, and Liu Yang's brain could hardly be turned around, just like a person who had eaten corn for decades, and suddenly someone said that it was poison that would kill people, where would anyone believe this statement.

But he didn't believe it, the other party said that his master's symptoms before his death, other limbs trembling, moody, speech pronunciation is wrong, many ordinary old men also behaved like this, but the blue-black short lines that appeared under the gum mucosa have never heard of a similar situation in the mouth of any old man.

"This, could it be that sooner or later you will be poisoned with mercury by taking the alchemy pill made by Dansha?" Liu Yang asked with difficulty, he thought that he also took pills when he was alchemizing, so sooner or later he would follow in the footsteps of his master and finally die of poison.

"That's right, it's not too late to make amends, mercury poisoning doesn't happen in a day, and the Taoist chief doesn't have to take that pill from today on."

Liu Yang Muran nodded, he hadn't recovered from the shock yet, but Yu Wenwen's unquestionable tone made him inexplicably feel a sense of trust, and there was no doubt in his heart.

"Daochang Liu, let's talk about the technical system of this alchemy."

"Technical system? What is a technology system? ”

"Well, it's just a mix of yin and yang."

"Oh, then the poor way is ugly..."

Yu Wenwen continued to listen to Liu Yang explain the theory of alchemy, and the alchemists took a fancy to gold and dansha, and called the "gold preparation" of artificial cultivation as gold liquid, and the dansha that has been refined several times as Shendan, and the two together are called Jindan.

How to combine the gold liquid with the elixir and various miraculous medicines, the alchemists continued to study, and the result of the research was the "change of yin and yang", and the theory of yin and yang was applied to specific alchemy, specifically, the drugs used in alchemy were divided into yang medicine and yin medicine.

Wei Boyang, a famous alchemist in the Eastern Han Dynasty, wrote a purely theoretical work on alchemy, "Zhou Yi Shen Tong Qi", using the yin and yang theory of "Zhou Yi" to explain alchemy.

There are a large number of "sun and moon" and "men and women" in the book, all of which use metaphors to illustrate that the basis of alchemy is the combination of yin and yang, and when the sympathy is conventional, the cultivation of Jindan will be successful.

"Yin and Yang are combined, this brain can be supplemented enough..."Yu Wenwen sighed in his heart, in order to pursue immortality, the ancient alchemists in pursuit of immortality, all kinds of whimsical ideas emerged one after another, but the starting point was wrong, then the result was naturally wrong.

"Lang Jun seems to be disapproving with the 'harmony of yin and yang'?" Liu Yang asked, when it comes to alchemy, his feelings are still very sensitive, and seeing Yu Wenwen's face showing disdain, he stopped explaining and prepared to 'argue with reason'.

"Uh, Dao Chief, please continue, continue..." )
