Alchemy in History

A special technique in ancient China. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info is also known as golden pill, alchemy, alchemy, yellow and white art. The content is very complex, and the central goal is to make people "immortal" by artificial methods, and to use the golden elixir to ignite ordinary metals such as copper and iron to transform them into gold and silver. Since there was a saying of "becoming an immortal" in ancient China, alchemy was first born in China. Alchemists believe that the human body can attain immortality with the help of some kind of miraculous medicine. "Dan" originally referred to dansa (i.e., mercury sulfide), and later came to refer to various drugs that were considered to be "elixirs" or "gold medicines".

When the feudal society developed to a certain stage, the productive forces were greatly improved, and the ruling class's demand for material enjoyment became higher and higher. Emperors and nobles naturally had two kinds of luxuries: first, a desire to possess more wealth for their pleasure; The second hope is immortality, so that their reign will be forever and for all.

Chinese alchemy originated in the 3rd century B.C., and in the Eastern Han Dynasty, the immortal ideas of the monks developed into Taoism, and the atmosphere of alchemy became deeply rooted in the people. The Eastern Han Dynasty Wei Boyang's "Zhou Yi Shen Tong Deed" is the world's earliest existing theoretical work on alchemy, and it is mentioned in the book that there were 600 pieces of "Fire Records" by alchemists at that time, which shows that fire alchemy at that time had accumulated a lot of empirical knowledge. The Jin Dynasty alchemist Ge Hong's "Baopuzi Inner Chapter" has made a detailed record and summary of alchemy since the Han and Jin dynasties, and his alchemy is divided into three interrelated parts:

1. Refining the panacea elixir, thinking that it is "the extreme of the fairy road".

2. Collect and process to make elixirs. These drugs include mineral, animal, and plant-based medicines, which are believed to play a role in "prolonging life", "nourishing" and "curing diseases".

3 points of gold and silver. Ordinary metals such as copper and iron are dotted into gold and silver, and various alloys similar to gold and silver are actually made using chemical methods.

In addition to the development of alchemy in China, in the 8th century, alchemy called al-kimiya (which is believed to have evolved from the ancient pronunciation of the Chinese word "golden liquid"), also appeared in Arabia, pursuing a panacea called al-ixir, hoping to use it to make people live longer, and other contents include alchemy and medicine. Around the 12th century, Arab alchemy spread to Europe with the influence of Islam.

The guiding ideology of the alchemists is idealistic, and as a result, their original purpose has not been achieved at all. However, after all, the practice of alchemy exposed the alchemists to various natural phenomena, thus improving their understanding of the natural world, for example, they worked in the laboratory day and night, accumulating a wealth of practical experience, thus putting forward a valuable idea: "Matter can be transformed into each other by artificial methods", and the gunpowder that appeared in the last years of the Tang Dynasty was the product of the practice of alchemy. Eventually, alchemy became the basis for the emergence and development of modern chemistry in Europe, and thus evolved from terms such as alchemy and alchimia to chemie (German), chimie (French) and chemistry (English) for chemistry. ---introduction

…………

Two crystal nuclei were placed in front of him, and Black Reef was completely dumbfounded.

Mu Ne's expression, his eyes looked at the wind incredulously, his thinking seemed to be unable to change, and his voice trembled a little when he spoke, "Crystal nucleus, you, where did you get it?" ”

There were two crystal nuclei, and one was the crystal nucleus of a sixth-order demonic beast, the shock caused to him was too powerful to be believed.

At the beginning, their thirteen brothers chased and killed for half a month, and twelve of them died, but the violent King Kong still didn't kill him, and if it wasn't for the appearance of the wind, he would definitely not have survived.

He had a deep understanding of the horror of a fifth-order demonic beast, how difficult it was to hunt a fifth-order demonic beast?

Now there is not only a fifth-order demonic beast crystal nucleus, but also a super-powerful sixth-order demonic beast crystal nucleus, how can he believe this?

Feng's talent and potential are the best he has ever seen, and it is not an exaggeration to evaluate him as a genius that he has not met in a hundred years, but he is just in the Void Breaking Realm, and he has just broken through, if the Void Breaking Realm can kill the Great Perfection Sixth-Order Demonic Beast, he will not die a dozen brothers.

Shocked, excited, and full of incredulity.

Feng scratched his head and smiled, and said, "Luckily, I just caught up with the two demonic beasts fighting to the death, and I became a fisherman." ”

It was very easy to say, but Black Reef was shocked to hear it.

The battle between the two high-level demonic beasts, the scene was extremely terrifying, the power to destroy the world was raging, and the wind was light, but he was thrilled in his heart, there is no such good thing in the world, no matter how good his luck is, if he has no strength, he will not be the opponent of the sixth-order demonic beasts of the Great Perfection.

"Big Brother Black, this sixth-order crystal nucleus is a gift from me to you."

As he spoke, the wind handed the crystal nucleus to Hei Jiao's hand, Hei Jiao shook slightly, and his hand subconsciously shrank back, and said: "The value of the sixth-order crystal nucleus surpasses that of ordinary gold exercises, refining it will get supreme benefits, and the cultivation will even break through continuously, I dare not accept such a valuable gift." ”

"Big brother, when I left the crystal nucleus of the Violent King Kong that day, I made up my mind to compensate you for a crystal nucleus, please be sure to accept it, otherwise I will be indebted."

Without the help of the crystal nucleus of the violent King Kong, the so-called amethyst's catastrophe and amethyst, the wind couldn't kill the blood-eyed mane lion at all, let alone win the two crystal nuclei.

And Black Reef treats him as a brother.

These winds are all in my heart, and I have been looking for opportunities to repay my kindness.

Although he is not a good person, he is a person who will repay his kindness.

Being able to enter the Yingyanquan Mountain Range, breaking through so quickly in the past half a year, it is all because Black Reef has been helping him, helping him without regrets, for Black Reef, entering the Yingyanquan Mountain Range is not much of a help to his cultivation, but he sacrificed his time to accompany the wind into the Yingyanquan Mountain Range, which is a great favor for the wind.

Not to mention compensating for a sixth-order crystal nucleus, even if the Black Reef wanted two crystal nuclei, he would not hesitate to give it to him.

Moreover, he could understand the feeling of cultivating hard without being able to break through, for Black Reef, this crystal nucleus was very important, related to his future cultivation path, and even more related to his path after joining the Liuyun Sect.

So, no matter what, the wind must make Black Reef take the crystal nucleus.

Looking at the sincere eyes of the wind, Heijiao choked for a while, and his heart was moved, the crystal nucleus is very precious to anyone, but he did not hesitate to give it to himself.

He remembered this affection in his heart.

At that moment, Black Reef didn't twist, picked up the fifth-order demonic beast crystal nucleus on the ground, and said, "Thank you." ”

Thank you, the two words are very heavy.

Black Reef felt it, he had stayed at the Ninth Order of Perfection for a long time, but he had been unable to break through after cultivating hard, and the crystal nucleus was very important to him at this time.

But the crystal nucleus is also important to the wind that has been transformed by the light purple crystal nucleus, and the growth of the wind has exceeded his imagination, and it will definitely shock the entire time and space in time, and resound through the sky.

Feng also wanted to argue and let Black Reef leave a sixth-order crystal nucleus, but Black Reef waved his hand to tell him not to say any more.

In the end, the wind said no more.
