Dansha, which has been used by both European alchemists and Chinese Taoists for a long time, is actually a mercury-containing mixture formed by some primitive primary processing of mercury ore. The www.biquge.info contains a large amount of mercury oxide, which is heated to a certain temperature to separate oxygen and liquid mercury.

The preparation of hydrogen is simpler, that is, the activity of iron atoms rises at high temperatures, and when water is added, the oxygen atoms in the water molecules will combine with the iron atoms, thereby replacing the hydrogen in the water.

Hydrogen and oxygen are also one of the earliest elements discovered by human beings, they are very distinct and common, and water is composed of these two elements.

Wang Mai's hydrogen and oxygen experiments today are unforgettable, and if he were a god, perhaps he would have created a religion at this time, and there would already be thousands of followers under his command. But he immediately announced the preparation method of these two gases, in order to dispel the uneasiness in people's hearts and pave the way for the elemental theory. These two preparation experiments are very simple, and I believe that everyone present will be eager to verify them after they go back, and after trying them in person, they will never forget them. If some of them are curious, they will explore the mysteries and discover more of the mysteries of the elemental world to be solved.

In the process of the formation of the modern scientific system, chemistry is different from physics, and it can even be said that it takes the opposite path. Physics is mostly a hypothesis-to-verification process, such as heliocentrism, Kepler proposed the hypothesis, Galileo provided the prerequisites for the hypothesis that could be proved, and Newton was the master. Chemistry is often the opposite, and the emergence of new elements in history is basically discovered in experiments, and the credit for this is inseparable from the alchemists who want to turn straw into gold.

The Chinese alchemists were among these Taoists, they were among the earliest pioneers of the chemical world, and it is interesting to note that their contribution to society was not the elixir they were proud of, but the by-product of alchemy. Gunpowder is one of them, and its role is needless to say; Tofu is said to have been obtained by accident when Liu An, the king of Huainan, burned medicine and alchemy, and Wang Mai remembered that a very popular diet documentary commented that it "supplemented the protein that the farming people urgently needed".

The theory of elements and Newton's theory of the movement of celestial bodies are the two pillars that make up the modern scientific worldview, one explaining the composition of the microscopic world and the other explaining the rules of the macrocosm, and the two complement each other.

Seeing Yuan Shoucheng's arrival, Wang Mai was not surprised at all, what he wanted was this kind of vibration effect, which could arouse people's desire to re-understand the world.

The old Taoist priest pushed away the tea and said straight to the point: "I don't know what the purpose of Assistant Teacher Wang's words and deeds today is? Please speak up. ”

Wang Mai smiled: "The Taoist chief said that he was joking, this is just some grandstanding gadgets, what purpose is there." ”

"You make a price." Yuan Shoucheng's first thought was to spend money to solve it.

Last time, Daomen spent a sky-high price to buy the manufacturing method of the astronomical telescope, but he did not expect to fall into an internal dispute, with the help of the astronomical telescope, Daomen has been believing in the Hun Tian theory for hundreds of years, and now someone has questioned it, fortunately, it was found in time, the telescope has been banned from use, which is considered to temporarily suppress the matter. But unexpectedly, a wave of unevenness rose again, and today's two experiments of Wang Mai directly pointed to the Yuanqi Theory, which undoubtedly shook the foundation of the Daomen. I don't know what this king wheat means, and everything must be against the Taomen.

"I guess the Taoist chief has heard of it, and there is no shortage of money in the next place." Wang Mai said calmly.

"Assistant Teacher Wang Tao Zhugong's skills have heard of it, since Your Excellency is not for wealth, why do you want to come to my Daomen for everything?"

"No, what you are doing is not intended to be aimed at the Daomen."

"Boy, don't be cowardly, what is wrong with my Daomen to offend you?" Li Zhongqing, who was next to him, couldn't hold back and asked.

"Why do you need to spend the belly of a villain with the heart of a gentleman?" Wang Mai laughed at himself, "This matter is beneficial and harmless to the Daomen and several Dao Masters, so why bother to force me to be an unknown little official?" ”

"That's nonsense!"

Li Zhongqing wanted to say more, but was stopped by Yuan Tiangang: "I'm going to listen to Assistant Teacher Wang's high arguments, what is the benefit of this matter to my Daomen?" ”

Wang Mai sighed leisurely: "Everyone, please come with me." ”

Several people followed Wang Mai's figure to the courtyard to see that two teenagers were busy sweating profusely. Yuan Shoucheng looked at it for a while, and he didn't see what the two were fiddling with. I only heard Yuan Tiangang next to him say: "Could it be that this is the method of making hydrogen that Assistant Professor Wang said today?" ”

"That's right," Wang Mai nodded, "the iron pipe in the middle is now red from charcoal, and now you can start now." ”

I saw Wang February's ladle of water slowly poured on one end of the iron pipe, and the leather tube connected to the other end of the iron pipe was soaked in a large bucket, and after a while, there were bubbles rising at the outlet of the leather pipe, Liang San held a glass bottle upside down on the outlet, and as time passed, the water in the glass bottle was gradually emptied, and Liang San quickly blocked the bottle mouth with a glass plate to prevent gas from leaking out.

Wang Mai quickly threw a lit wooden stick into the glass bottle that had just been opened, and everyone only saw a blazing light shining from the bottle, and at the same time heard a cracking sound, like a muffled thunder.

Yuan Tiangang and others have seen the hydrogen ignition experiment during the day, and now they have a closer look, and they have a more feeling. Yuan Shoucheng saw this situation for the first time, and he was immediately shocked.

"The theory of meta-energy is too coarse, and the real world is much more complicated. Several Taoist masters are all masters of the Dao Sect, and they must have been deeply touched. Wang Mai said.

"What do you want to say, you might as well say it." Yuan Shoucheng asked with a frown.

"Quite simply, the world needs a finer theory to support the existence of all things."

"Your Excellency, do you want us Daomen to overthrow the Theory of Yuan Qi?"

"Not bad."

"What a big breath." The three of them looked at Wang Mai as if they were looking at fools, and they turned around and were about to leave.

"If you don't make this decision today, you will regret it in the future." The voice behind them stopped the three of them again.

"Your Excellency, are you threatening us?" Yuan Shoucheng's smile made people shudder.

"How dare you?" Wang Mai arched his hand, "Yuanqi is not the words of the Daomen family, but the Daomen has benefited the most, such as the big tree in the storm, if there is anything in the future, it must be the first to bear the brunt." ”

The three of them lowered their heads, all thinking about the meaning of Wang Mai's words.

"If the Daomen can first innovate itself in the midst of changes, then you will benefit the most in the future." Wang Mai handed Yuan Shoucheng a thin booklet, "This is a detailed record of some of my summarized views, and I will give it to Daomen today, and after reading it, I will ask the three of you to decide." ”

Yuan Shoucheng turned the first page, three words came into view - elemental theory, and then turned back is the first article "gas", the first two are hydrogen and oxygen that I have just seen today, which not only writes the preparation process, but also summarizes the characteristics, which is very detailed. The second article is "Liquid...... and the third article is "Solid......

The booklet summarizes the composition of all things into small particles that are difficult to see with the naked eye, called elements, and lists dozens of common elements, such as copper, iron, mercury, charcoal, and so on.

Several people quickly took turns reading the booklet, and the expressions on their faces were very complicated.

"Why?" Li Zhongqing couldn't help but ask.

"If the three of them must have an explanation for the motive of this matter," Wang Mai thought for a moment, "it can be boiled down to the word "profit." ”

"Leigh? I wonder what your interests are in this matter? ”

"For me, it's natural to exchange it for friendship. For Daomen, the benefits are even greater. ”

"I want to hear about it."

"First, if the Daomen can perfect this theory in the future, then they will truly grasp the origin of all things. Second, this study was despised by Confucianism, and Taoism will be successful in the future, and it will surely leave a name in history......"

"Regardless of the truth or falsity of this elemental theory, but speaking of which, these are the words of your family, although the old Tao is not talented, he also knows the allusion of painting bread to satisfy hunger."

"Don't worry, there is a third point," Wang Mai stretched out three fingers, "This benefit is immediate, there are many unknown smelting knowledge summarized in the booklet, and based on this alone, the Dao Sect will be the richest sect in the world in the future." These are all given away for free under the next, and they don't take a penny, how about the three of them? ”

"To put it lightly, if this elemental theory is really popular in the future, the world will only think that it is my Dao Sect that has achieved it with the help of Assistant Teacher Wang. Your Excellency is cunning, and if it succeeds in this matter, it will have its own reputation; If it fails, it will only cost a few thousand words of pen and ink in this booklet, and in the end, I don't know how much benefit my Daomen will get, but Your Excellency will sit back and enjoy it. Yuan Shoucheng finally understood the reason why Wang Mai took so much pains, this Wang Mai was young, and he played with the two doors of Buddhism and Taoism between applause, which was really not simple. I heard that Buddhism has postponed the debate because of the mystery of the microscope, and now I want to harm the Taoist sect, and Confucianism is so blessed that there is such a powerful figure.

Yuan Tiangang and Li Zhongqing also suddenly realized when they heard this, and they both looked at Wang Mai with unkind faces.

"Ha......" Wang Mai couldn't help it, and laughed out loud.

"Why is Your Excellency laughing?"

"I smiled and looked suspicious, and the Daomen were all cowardly."

"You ......"

"When did you say you wanted to have it all to yourself?" Wang Mai pointed to the booklet in Yuan Shoucheng's hand, "After today, I have nothing to do with this "Theory of Elements", and no matter what the results of the Daomen have in the future, it has nothing to do with Zaixia." ”

The three of them left the Guozijian with a lot of trouble, and as soon as they returned to the house where they were staying and sat down, they couldn't wait to discuss the matter.

"I still don't think this king wheat will be as simple as he said." Li Zhongqing said.

"But now that I think about it, I can't tell what his motives are?" Yuan Tiangang frowned, "If he really wants to be unfavorable to our Daomen, there is no need to give this book to me." ”

"Everything is like a fog now," Yuan Shoucheng shook his head, "Many of the secrets in this booklet are indeed unheard of, so let's verify the truth first." ”

"What about this king wheat?"

"He offended the old monk Huicheng, do you think Buddhism will stop there?" Yuan Shoucheng stroked his beard and sneered.
