"Although it is from the Li family in Longxi, the red flowers and green leaves are all a family.

Therefore, I still have some understanding of the family affairs of the Li family of Zhao County.

This time to send their son and family, obviously their preparations are also in a hurry,

Liang Guo Li's branch did not have a woman of appropriate age to have a baby. ”

The little dragon king snorted coldly,

"I'm afraid that Li Tianci is no longer useful!"

"Emperor Xianwen also gave Li Tianci a marriage, and chose a woman of appropriate age in the eldest grandson of the Xianbei nobles and the Dugu family.

This marriage standard is also on par with the royal family.

So officially, Li Tianci also has three heirs of the Li family.

The youngest one is still in infancy, which shows that he is still in the prime of life! ”

Qingyun's brain circuit is naturally relatively simple, so he also asked curiously,

"I'm afraid that those descendants of Daja have given up the throne, right?"

Li Shenjun naturally scoffed at this,

"Give up? In fact, if the heir born in the emperor's family is completely disconnected from the Li family, there will be no evidence left.

In order to avoid suspicion, we can't see each other again in this life.

But if this unspoken rule is a royal scandal after all,

Once the time comes when someone decides to erase it, I'm afraid that there will be no one left behind.

So for those who escaped into the Li family,

Only when you see your direct bloodline ascending to the throne will you feel at ease.

It's a matter of life and death, the survival of the family, how can they give up? ”

The little dragon king sighed,

"The main purpose of our coming today is not for that Li Tianci, it's best not to see it.

Since such a big man came, he would be arranged to meet guests in the main hall if he wanted to come.

Second brother, you are familiar here, is there a way to take us around the main hall?

Thinking that those Nanqi people would not be involved in such pickled matters, we went directly to them. ”

Li Shenjun was also overjoyed when he heard this,

"I'm going with you!"

"Oh? Didn't you come here to inquire about the Li family's affinity? What are you doing with us? ”

"How can I insert the kind of pomp and circumstance in the main hall at this time?

Yesterday there was such a big battle in the Hurry Army, and I wanted to see if any old friends had arrived. ”

Qingyun thought of something similarly, and nodded at Li Shenjun,

"The Ren Shentong you mentioned that day did appear in the Tai Chamber."

"Oh? Is he here too? ”

Xiao Yan was also slightly moved.

In the past, it was green, and the palace of the king of Jingling, the eight friends drank and sang, and the world was uneven,

Thinking about it at this moment, it still feels like yesterday.

It's just that now this supernatural power is stepping on which boat, even his old friend can't see clearly.

Seeing the shape of the moment, he stopped talking nonsense, and stretched out his right hand to everyone.

"Come with me, everyone!"

The mountain path is secluded, an ancient road with sheep intestines, and it is difficult to accommodate two people side by side when it is narrow.

Sometimes I need to cross the stream with a single tree, and sometimes I need to climb the wall with mountain vines,

After walking for about half an hour, I saw another courtyard.

Here Qingyun naturally knows, it is the place where the day of the dawn of Maitreya is the mirror of the light,

It's just that at that time, I walked all the Yangguan Road, where did I know that there were such strange paths that were not found in the secluded forest?

Push open the chai door, and there is a courtyard.

There are some simple rainproof sheds,

A large tree trunk stretched out in the middle, covering almost half of the space.

There is also a slightly thinner one next to it, with a straight trunk and dark color, and the strange fragrance emitted is refreshing.

It was apparently temporarily designated as a storage warehouse for Yizhou timber.

When he heard the voices of people coming from the courtyard inside, he was very relieved, and it seemed that the construction of the flying kite had not been delayed by the presence of distinguished guests, so he hurriedly attracted people inside.

The courtyard is obviously more spacious, filled with processed timber of various sizes.

The body and wings of the flying kite are clearly formed.

However, what surprised me was not the progress of the carpentry, but the kite admirers in the courtyard at this time.

The room has long been abandoned, and there are only four people left.

Kanundo Naga and Hojo are naturally familiar with each other,

But the thin old man behind him and the middle-aged Taoist priest with a red face didn't know each other.

At this time, the identity of the guests who need to be accompanied by the head of Guanyun is really not difficult to guess.

It's just that it's a little embarrassing to meet in this form,

I wanted to dodge but didn't dodge, I just bumped into my arms.

When the thin old man saw so many people popping out of the backyard at once, he couldn't help but smile and greet everyone slightly.

didn't wait for the introduction of the head of Guanyun Dao, but he opened his mouth first,

"Yes! This is Tao Tongming's high apprentice, right?

Quite a teacher's style, full of cleverness.

Kindness! Not bad!

Ay? Tyre is here,

Come on, come on, it's been a long time, come and let the ancestor see! ”

Tao Tongming is the expression of Mr. Huayang Tao Hongjing, and the person who calls him so is an elder.

Ti'er is Li Shenjun's nickname, and if he can call out this name, he must be very familiar with the Li family in Longxi.

As soon as these words came out, who among the people present couldn't guess the origin of this person?

This old Taoist is naturally the old man of the Li family in Longxi, the master of Xuandu Temple, and Li Xuandu.

Li Shenjun could only move obediently to a chick, and lowered his head to let his thin palm caress the top.

"These young friends are so tight!

Why didn't Ti'er introduce him to the ancestor? ”

An old monster like Li Xuandu can't be judged by seniority.

Therefore, when he spoke, even the Daoist of Guanyun did not dare to interject.

Li Shenjun carefully introduced the people who came with him one by one,

Li Xuandu nodded when he heard it, and he didn't forget to praise two sentences, most of them were praised by the elders,

For example, Tuoba Zhong Kui was famous in the past,

Qing Chen Erxia was sharp back then,

Xiao Shun's hand blade Xue Suo'er's past,

Taishi is a famous family for generations......

If a person lives for a long time, it is just a book, and there are so many stories that I can't tell enough.

When Li Shenjun finished his introduction, the old Taoist stroked the skeleton of the flying kite with his hand, and said with a smile to Zu Yuzhi,

"I heard you want to use this thing to fly across the two peaks?"

Hurriedly answered.

"It's almost hot!

Young people are always neither light nor heavy.

This flying kite can only swoop, not rise,

Rushing to the opposite cliff, you can only scatter a puddle of broken wood, what can you do? ”

Yu Zhi and Qing Yun looked at each other, although they knew that what the other party said was a bit too harsh, after all, as long as the flying kite was piloted properly, they were still sure of their self-preservation.

But they also know that the success rate of this program is not very high.

Coupled with the fact that the seniority of the old Taoist priest is there, where do they dare to talk back?

Only Nono can say yes.

"Phew, what is it!

I'm old, but I'm not confused!

The most supreme of you is that you are not convinced,

Think I can't see it? ”

Yu Zhi and the others couldn't touch this old man's temper at all, so they didn't dare to speak.

Fortunately, the old man didn't have the intention to embarrass the juniors, and glanced at Qingyun,

"I heard that the Dangong Master is out of the ghost valley, I don't know if it's true?"

Qingyun bowed to be.

In fact, he also heard about the past of Tan Palace from Caiting, Seke, and the vague places.

The great god in front of him was not easy to coax, he only picked out some brief and conclusive inheritance relationships, which roughly explained the bonds between the Guigu Tan Palace.

The old Taoist priest stroked his beard and nodded secretly,

"Well, the little guy has a good heart.

Pragmatic and true, what is said is conclusive evidence, and there is no light quotation of legends and exaggeration. Very good! ”

So saying, he took out a booklet from his sleeve,

"In recent years, the old Tao has refined the Taoist collection of three thousand,

I dare to be interested in all kinds of scattered solitary books.

I recently got a book.,It has a lot to do with your Tan Palace.。

I came here all the way from Fenxi, and I was bored on the road, so I happened to copy a copy, so I'll give it to you! ”

Qingyun hurriedly thanked and took it, only to see that the cover book had the words "捭阖策" , and said secretly in his heart,

"Isn't this a copy of "Guiguzi"?

Although it has something to do with the Tan Palace, there are many copies of this book, and ordinary bookstores sell it, what's so unusual? ”

He was muttering in his heart, the old way was like a roundworm in his stomach,

"What? You are thinking in your heart, what is so unusual about an ordinary "Guiguzi", yes or no? ”

Qingyun hurriedly said that he didn't dare.

The old Taoist priest snorted coldly,

"Have you read this book?"

Qingyun should be.

"Then test your eyesight first, and see what difference you have in this copy of the manuscript?"

Qingyun's heart sank, and he hurriedly opened the scroll in his hand and looked through it.

At that time, the hand-copied books were naturally not like today, where the table of contents was marked first, and it was clear at a glance.

It is really not easy to check the addition or subtraction of this content.

Fortunately, "Guiguzi" is also a must-read book in the main gate of the Tan Palace, Qingyun took a look at it, and really got a glimpse of the mysteries.

"Guiguzi", which is divided into three articles.

The first twelve volumes, written about the art of scheming and scheming, are the most complete and most famous part of the world.

The novella is said to be divided into two volumes, the upper volume is turned into pills, and the lower volume is chaotic, and the Qin period has been lost.

In the next part of the spell, only the outline remains, and the content is incomplete.

Among them, the gods are sheng, the ambition is raised, the circle is turned, and the heart is taken (see the chapter of the "Zhongjing"), but there are only a few words left, and it is difficult to see the whole leopard.

However, the manuscript in Qingyun's hand was titled Zhuan Pill and chaotic for dozens of pages.

As for the second part of the spell, although it is not complete, it is much more detailed than the ordinary manuscript, and the principles of each law are briefly analyzed.

Zu Yuzhi on the side has actually been looking at this book with his eyes.

The ordinary version of "Guiguzi", he is naturally familiar with it, so he also quickly discovered the peculiarities of the manuscript in front of him.

He took advantage of Qingyun's time to turn back and see the novella and examine it carefully, and grabbed the latter with his shoulder.

Qingyun immediately understood, slowed down, and flipped through carefully.

The two articles of this Zhuan Pill are neither conspiracy nor magic, but some discussions on the principles of nature.

The Zhuan Pill chapter believes that heaven and earth are divided into yin and yang, and yin and yang are mutually reborn to maintain the balance of the world.

Day and night, cold and heat, alternately turning circles,

There are male and female beasts, male and female men, and lightning thunderbolts.

Qi has turbidity, or chemical or combined, mutual checks and balances.

The chaos is even more profound,

The opening is clear, the one who is the one who is born, the place where the wings are born, the wings are opened, and the ancient sages can't ask for it;

Troublemakers, reason.

(The Kangxi Dictionary cites the Jade Chapter, which is a dictionary of the Northern and Southern Dynasties, and its explanatory teachings originate from ancient Chinese.) ）

Those who are incurable want to be cured (out of the "Saying"),

Those who do not understand must discern their reasoning.

Those who are in turmoil, those who are brave open their wings to discern their reason,

It may be possible or not, and if you don't bow to it, it is difficult to distinguish in the end.

This text makes the hairs stand on end,

It turns out that this chaotic article is some settings and assumptions for flying technology.

Although the article says that these theories are still in the exploration stage, after all, they are great wisdom beyond the times.

For a tech nerd like him, the attraction is naturally overwhelming.

He couldn't help but snatch the manuscript from Qingyun's hand and look through it carefully.

Li Xuan on the side saw it in his eyes, just smiling.

Of course, he is the oldest here, and he doesn't speak, so everyone follows and watches the play, without saying much.

It is said in the chaos chapter that the ancient sages have long tried to fly to the sky, which can be traced back to the period of Emperor Taiyi of Shangzu.

At that time, the Yin Shang tribe was still headed by the Xia Hou clan,

Among the Yin tribe, there is a king who is divided into slaughtering land-Wang Tu, who is a supporter of the flying arts.

At that time, he made a gossip chair, hidden in the eight doors, with the number of forty-eight,

Take yourself as the Jiazi Shengmen, and place the remaining forty-seven bamboo tubes to fill the Yang Yuan.

He then set himself up on a high platform and ordered forty-seven servants to detonate Yang Yuan at the same time.

The gossip chair went straight to the sky, and future generations did not know its trace.

In Guiguzi's opinion, this Wang Tu's flying weapon is at least half successful.

But the entire fuselage only took into account take-off, without taking into account control and landing, and was a failed design.

He then began to comment on various ways to improve these shortcomings, including the male flying kite.

He thinks that the flying kite solves the control and fall, and the yang yuan tube solves the lift.

The combination of the two makes for a perfect flight.

When Zu Yuzhi saw this, his voice trembled a little with excitement,

"Dao, Dao Chief, what is this Yang Yuan?"

"Oh, you can take a look at the previous pill transfer chapter."

Zu Yu hurriedly flipped forward,

The two volumes are next to each other, and I didn't turn a few pages before I found the method of making Yang Yuan:

Yin is the ultimate yang, and yang is the ultimate yin.

The salt pond of the West Sea, the morning dew in the rainy season, the yin and yang of heaven and earth, and the sex is extremely violent.

A hundred-foot well, a place of extreme shade, with filthy water,

Wait for the air to dry and the water will dry up, and take its condensation frost, which is the yang yuan.

When Yang Yuan is exposed, it explodes, affecting a hundred zhang square circle.

Plugging it with a cylinder, leading to an open fire, it can reverse the sky, break the clouds and run through the sun, and this is also a god.

Only refining is not easy, and storage is especially difficult, be careful!

"This!"

When Zu Xuanzhi read this, he was quite disappointed in his heart.

It seems that the materials used in this Yangyuan are extremely exquisite, and they must be made of the morning dew of the rainy season in the salt pond of the West Sea as raw materials, and there must be a dry deep well in the Gobi to prepare, and Guiguzi also sighs that its preparation is not easy.

At this time, where can I get enough raw materials to improve the flying kite?

Li Xuandu was not surprised when he saw this, and asked with a twist of his beard in his old eyes,

"Ancestral children.

According to this book, if there is Yang Yuan to help,

Do you think it can help the flying kite to soar on the ground? ”

Zu Xuanzhi thought about it, and took out a thing from his bosom,

"This is the day before yesterday I took a few corners and built a wooden magpie.

The proportions of this wooden magpie are secretly in line with the flying kite, and I have tried to fly many times when I am bored.

There has been a rough study of the force points required to maintain its flight.

I also have some less powerful Yehu powder here that can simulate Yang Yuan for power tests.

I think the forty-seven points taken by Wang Tu are too mysterious and not practical.

Using the improvement of the test results, it should be possible to provide lift for the flying kite more reasonably. ”

"Oh! Then count yourself brat lucky.

I did bring some homemade yang yuan here,

Originally, I was waiting for your master to come and verify the technique of "Ghost Valley" with him.

Now that your flying kite has been completed, if you can use it to transform the wind and fire flying kite, it will naturally be even more wonderful.

It's just that this treasure is really difficult to make, and I have been poor for ten years, and I only get a bottle.

And all of them must be balanced with saltpeter water to prevent the container from overheating.

Such a decade of saltpeter consumption,

Hey, if it weren't for the Li family in Longxi, it might be a poor country, and it might not have such technology and resource support.

With such precious materials and ten years of savings, I don't want to be ruined by you kid! ”

"No, it won't! I will try again and again, take the safest way, and let the flying kite take off! ”

"Hmmm! Seeing you kid is like seeing your master back then.

It's not in vain for a bad old man of my age, hiding in the Northwest Wilderness, poor and poor, sorting out "Daozang". ”

Xiao Yan is a young man who is listed among the eight friends of Jingling, with a romantic literary style, talking about scriptures and classics, when did he ever descend?

Hearing this, I can't help but interject,

"This Taoist chief, eavesdropping on the world's poetry and books,

It is better than "Sutra", "Poem", "Son" and "Collection".

This so-called "Daozang", but the Taoist princes say, can there be geometry in the world? ”

When Li Xuandu heard this, his eyes were quite displeased.

He turned his face to look at Xiao Yan, only to see that the other party's eyes were clear, full of curiosity, and he didn't seem to be deliberately teasing, so he was relieved and patiently explained,

"It's a good way, it's a very good way.

Taoism has never been a single word, but the law of the operation of all things in heaven and earth.

Confucian Legalism emphasizes reason, Taoist Yin and Yang emphasize Taoism,

We don't study the so-called 'small words', but only the laws of the world.

Of course, there are also a few who go mad, drum up mysteries, and fall into the evil way.

However, the so-called evil does not prevail over the good, and the doctrine of the right way must be sorted out by someone in the end.

My Chinese characters have survived for thousands of years,

For thousands of years, there have been countless books outside the "Sutra" and "History".

However, if you don't follow Confucianism, you won't list the scriptures, what a pity?

Fortunately, there are always characters like Wang Guigu, Zhang Pingzi, Ge Baopu, Lu Jianlone, Kou Fuzhen, and Tao Huayang to maintain the justice of the avenue.

Mr. Xi Jianshan met with him, and first mentioned the classification of the three-hole method, and rearranged the thousands of books collected.

The so-called three-hole method is based on this "Guiguzi".

The first part of "Guiguzi" is close to the Confucian princes, writing science, applying the name, and explaining the basic views.

The middle part puts forward some ideas about the law of the avenue, records some well-documented designs, and adds its own annotated comments.

The next part is some hearsay, with the secret techniques that cannot be explained at present, for future generations to verify and refine.

All these three kinds are classified into three holes, which are cave mysteries, cave truths, and cave gods.

Metaphysical doctrine, the art of pure talk is the cave mystery;

Explain the truth and seek the truth, and say that there are things that are true;

Chasing the gods is different, and the sea is well-known as the god of the cave.

Those who think that having read a few "scriptures", "poems", "sons" and "collections" are rotten Confucians who have read all the books in the world,

It is useless, insufficient and conspiracy. ”

Li Xuandu completely refuted Xiao Yan's views, which seemed to be-for-tat, but Xiao Yan was not angry at all.

Today, he saw with his own eyes the separate volume of "Ghost Valley" contained in "Daozang", and the essence of the addition and supplementation of the dead and the deficiency in it is the essence.

And the first part of the world is well preserved,

I'm afraid it has something to do with the old Li Zuoxiang and Dong Ram's failure to suppress the dethronement of the hundred schools.

If you don't read the "Classics" and "Classics", you don't know the truth of China;

Only reading the "scriptures" and "classics", it is difficult to understand the millennium road.

Erudite but not pedantic true countrymen, how many people have been there throughout the ages?

Li Xuandu dragged his old voice and continued,

"The avenue is vast, how can you be poor with pen and ink.

With the thousand-year accumulation of the Li family in Longxi in Daomen, although Lao Dao was able to collect many scattered fragments, he still did not see the way of the Dao.

Compared with Tao Tongming's junior, he thinks he is much worse.

Many expounding subtle words require a sensitive person like Mr. Tongming to be able to peek through the cave and follow the cave to return to its truth. ”

Li Xuandu squinted around, and saw that it had become his own hall of words at this time,

Everyone was submissive and lost interest.

So he turned his head to look at the chief of the cloud-watching road,

"Today's children are too restrained,

Guanyun, why don't you borrow a place here and let's sit down and talk?

Are you here, should you not ban bars? ”

Kou Guanyun hurriedly smiled,

"Ah, it's forbidden to drink alcohol in normal times.

But there are also some water and wine that the believers worship for sacrifice.

I think it's also close to dinner, why don't you ask the old fairy to move to the inner hall and talk about it? ”

The vegetarian fasting in the inner sanctum has long been ready to stop,

Although there are a few more uninvited guests, it is just a matter of adding a few bowls of chopsticks.

It is rare that this old fairy is in good spirits, and naturally no one wants to spoil his interest.

Li Xuandu, the old man who does not cultivate, must be a drinker on weekdays, and the first thing he does when he sits down is to raise a glass.

I didn't invite anyone to drink together, but I just made a bowl of wine first to try the strength of the wine.

According to his qualifications, the seat he sat was the chief priest at the wine station.

The first cup of sacrificial wine at the beginning of the feast should have been for him to toast and toast,

It's just that such a booze is not an ordinary rule.

His first bowl of wine was obviously not very happy, and he rolled a pair of white eyebrows into a snake shape, and scolded angrily,

"What kind of, fade out of a bird.

Compared with Fenxi's white wine, it is really not as good as water. ”

This talked about wine, and finally someone dared to talk,

The little dragon king also held the bowl and said with a smile,

"Bai Fall's wine is in Luoyang, it's worth 10,000 gold.

At present, only Liu's Distillery sells it, and the annual production is very limited.

It is said that it is necessary to make the deer in the spring, expose the urn in the summer, and leave a hole to lead it with a reed pipe.

Take its white fall, and then seal the mud cellar.

Even if the weather is good and there are few rainy days, only a few bottles can be produced.

If you're unlucky, in a rainy year, you won't be able to fall out of half a bottle! ”

The old Taoist priest listened to it all his hair,

"Rubbish! Rubbish!

That, that kid from the ancestral family,

The next time you go to Luoyang, take a look at this Liu's winery,

Teach these wastes.

I have thousands of magic weapons in my "Daozang",

Why is it that the people of this world have abandoned it because of those corrupt and mean words? ”

Zu Yuzhi also responded with a smile,

"According to the Little Dragon King, this white fallen liquor should have used the distillation method to increase the mellow of the liquor.

The use of the distillation method was established by the Dan family as early as the Han Dynasty.

If the distilled fruit can be made into a good wine, this is indeed not a difficult task. ”

Li Xuandu smiled with satisfaction and teased Xiao Yan,

"Look, what are my Taoist methods?

To the south of the Tao Tongming belly in the warp and weft,

thought that Xiang Zai was also at ease. ”

Xiao Yan also raised his glass and drank it all,

"Then inherit the auspicious words of the old gods.

If Xiao can one day step on the Dan Majesty,

I will recommend Mr. Huayang as the prime minister. ”

The old Taoist priest waved his hand,

"Hey, no hurry, no hurry.

There will come a day,

Your position will be a little higher than your current expectations. ”

Xiao Yan is quite ambitious,

Single-mindedly set things right for the Southern Qi Dynasty, and led the dynasty to enter the phase.

At this time, Li Xuandu said that his future achievements would be a little higher than his expectations.

How? Can you still defeat Emperor Qi?

At this time, Xiao Yan naturally did not have this awareness, but just regarded it as a joke, bowed his head and laughed without saying a word.

Seeing that the atmosphere has been set off well at this time,

The chatterbox of the crowd is gradually opening under the influence of alcohol, and it is not as restrained as when they first met.

Li Xuandu looked around with his old eyes, knowing that the time was almost up, and it was time to start chatting about some dry goods, so he dropped the wine bowl heavily.

There was a "pop", and the audience fell silent.

》》》》》 time to knock on the blackboard《《《《《

We will talk about the history of Chinese distilled spirits later, and we must be reasonable, well-founded, and put forward ironclad facts to explain how the birth era of Chinese distilled spirits was seriously underestimated.

In this section, we will focus on two points:

The first is the legend of "Ten Thousand Households Flying to the Sky". This legend may be more widespread abroad than at home, that is, the first person to make the flight attempt was made by a Chinese official named Wan Hu, who was lit by forty-seven servants and ascended to heaven by flying chairs.

This record is now often referred to as a pseudo-canon, because the legend originated in foreign scientific magazines, and there is no corresponding original canon in Chinese canons. This story first appeared in Scientific American magazine in 1909, and has been widely cited and refurbished in various books and newspapers, and finally brought back to China by Professor Qian Xuesen.

The main reason why this original text cannot correspond may be the restoration of the phonetic translation. Attempts such as flying to the sky were basically Taoist studies in ancient China, and Confucianism did not play this. So it's hard to find in the main scriptures. In most versions, this Wan Hu is from the Ming Dynasty, presumably because it is a confirmation that gunpowder has been born. But in fact, in the original version in 1909, this version says that a nobleman named Wang Tu made an attempt in 2000 BC to try to fly into the sky using kites, seats, and forty-seven rockets. In 2000 BC, on the occasion of the Xia Shang dynasty, if this original text really exists, it must have come from a certain pre-Qin son.

In the pre-Qin attempt to fly, we can see that there are already flying kites and magpies introduced above. Among the pre-Qin technology houses, Guiguzi may be second only to Gongyizi and Mozi. And the book "Guiguzi" does have a story about "Chaos", which is often mentioned in historical biographies. There is nothing wrong with interpreting it as an inquiry, based on various interpretive literatures.

The so-called slaughter of the country is indeed a sub-surname tribe that existed in Qilu (the area of activity of the Yin Shang tribe before the establishment of the country) during the Yin Shang period. Therefore, this article uses "Guiguzi" to restore Wanhu/Wang Tu Feitian, although it is not a historical fact with conclusive evidence, but there is no logical error in the setting.

In fact, many of China's books have not really died. Most of the Taoist collections, led by the Dunhuang collection, as well as the unearthed slips, were looted by foreign scholars who did not have the ability to really decipher them. Among them, there are a large number of non-obscure texts that have not been passed on. Nowadays, Tsinghua University and Peking University are only the tip of the iceberg of these cultural relics, but only this corner contains many records about the Xia Dynasty, the early Shang dynasty, the secrets of the first emperor, as well as the medical books and Danfang, and the military genealogy. Earlier, we mentioned that German scientists cited the example of the book "Pinglong Zhi", with the status of "Scientific American" magazine back then, it is expected that it will not be groundless.

The second point that needs to be explained is naturally about the record of Yang Yuan. We often see some mystical records in ancient Chinese Taoist treasures, Danfangs, and medical prescriptions, with many harsh conditions attached, such as where and when something is needed, which seems quite unreasonable. But we need to take into account that "scientific research" at that time was in a state of theoretical scarcity. The whole world was in the same state in the Middle Ages and even before, and we will analyze the impact of such theoretical barriers later. Now, in short, research at that time was mainly in a state of "learning from failures and very few success stories". So there are a lot of qualifications that seem ridiculous, because most of the experience comes from the summary of successful cases, and you don't know why it is, and you can't filter the necessity of some conditions.

However, the author emphasizes here that in the vast majority of cases, these experience summaries are still based on and reasonable, and those who cannot see through them naturally feel ridiculous. For example, the setting of yang yuan in this book actually simulates the preparation of perchlorate. Perchlorate can be generated in nature under certain extreme circumstances, and according to the results of modern scientific research, aerosols with higher salinity can produce perchlorate such as sodium perchlorate in the state of lightning strike. Therefore, the rainy season frost in the salt pond of the West Sea is the natural substance that is most in line with this setting. The filthy water contains ammonia, and the crystals precipitated by air-drying with perchlorate in the dry Gobi Kar well, with sodium perchlorate, ammonia and other components. What can these components be used for? To date, perchlorate, a solid fuel for rockets, is a commonly used initiator and oxidizer, and they react violently when exposed to heat, decomposing and releasing a large amount of gas, producing a strong thrust.

The storage of perchlorate needs to be protected from light and high temperatures, but fortunately, the technology of saltpeter cooling has long been mastered by Taoists. Of course, such a technology does not have mass production and can only become a plaything of the Dan family. In fact, the basic research of Taoism in chemistry could prepare many chemical compounds, but under the conditions at that time, there was a lack of mass production basis, so it was out of public life. Because it was not understood, it was questioned, and over time, it precipitated with those tricks and tricks, and buried together with the light.

Although Yang Yuan and Wang Tu Feitian are a kind of reverse fitting based on foreign scientific sketches, they are not supported by published ancient documents. However, in the back of this article, many misreadings of ancient science will be deciphered, whether they are true or false, they will be truthfully noted.
