A small, faint candle was carefully placed in the flask.

Almost at the same time, the candle burned violently. The wick crackled, scattering a bright light through the transparent glass.

One person was pleasantly surprised, "Oxygen!" ”

One person was excited, "Oxygen!! ”

One person was steady, "Don't worry, you have to prove it." ”

The gas collected by the same receiving device is loaded into a new flask.

The slender medicine spoon threw the black iron powder into it, teased it with fire, and it burned with a sneer.

"Oxygen!"

"Oxygen!"

“……”

Another flask that had collected the gas, and the charcoal with the spark was thrown into it, and in an instant, it turned into a ball of flames.

Plugging the cork, the charcoal quickly burned clean, poured the clarified lime water into the flask, shook it slightly, and the transparent wall of the bottle immediately turned cloudy milky white.

A hand held the cloudy flask alof, "It's oxygen!" ”

In the hall, where there were more than 100 people sitting and standing, no one denied this assertion.

Charcoal gas - charcoal, charcoal, oil, paper, wood, as long as it is a carbonaceous material, the gas that will be produced after combustion - through guò clarified lime water, will produce lime. This is a well-known fact among the members of the Nature Society.

The preacher, who is also the demonstrator of the real yàn, uses the three real yàns to clearly prove that the gas collected from the real yàn device is determined to be oxygen.

The old man sitting at the front was the first to stand up and applaud, and then led all the participants in the hall to stand up one after another.

Hydrogen combustion produces water, which was confirmed very early on, and many people present have done this.

But conversely, no one has succeeded in splitting water into oxygen and hydrogen.

To this day, a scholar with a test device of his own design has proved it to everyone present.

Batteries, a sub-project of electricity at the forefront of research, are used to electrify water and then collect the resulting gases through a special glass tube.

One of the electrodes produces oxygen, and the other produces hydrogen—before oxygen is real, the preacher has proved that it is hydrogen with the same three reals.

Splitting water and proving that water is not elemental is one of the more than 20 unanswered questions that have been publicly solicited for proof within the Nature Society.

Now, someone has finally proved that water is not an elemental element, but a combination of oxygen and hydrogen, and the ratio of the combination is one to two, that is, one part oxygen and two parts hydrogen can produce one part water. So the molecular formula of the water molecule can also be determined.

This truth directly overturns the judgment of the ancients, which is enough to glorify a lifetime.

has always been a calm preacher, and at this time, he couldn't help but feel agitated in his heart, and tears appeared in the corners of his eyes

Applause. The old man in the front row walked up to the podium and came to the side of the speaker, and the audience fell silent.

That old man is the head of the Great Song Dynasty ministers, Su Song of Pingzhang's military affairs.

Walking up to the preacher, who was already too excited to speak, Su Song patted him on the shoulder, then turned around and faced everyone.

"Eleven years ago, we discovered hydrogen."

Su Song's voice was full of anger.

"Eight years ago, we confirmed that hydrogen combustion produces water."

Everyone in the audience nodded, and many of them made real things with their own hands, subverting the opinions of those around them.

"Three years ago, we confirmed that hydrogen and oxygen are burned and only water is produced, and that hydrogen is a component of water."

Yes, many members are on this reality and understand why the conclusion must be rigorous.

This real yàn is an extension of the previous real yàn, but the previous real yàn cannot replace this real yàn.

"And today! …… Xia Xingyan's new real yàn from Chen Liu's design proves that water is composed of hydrogen and oxygen in the opposite direction, and it can be completely confirmed that this ratio is two to one! ”

Again, applause rang out, for Su Song's speech, for Xia Xingyan's discovery, and for this breakthrough reality.

Coming out of the shaded room, the sun was scorching overhead, but no one cared about this little thing.

All the members who listened to the report were discussing the preaching that had just ended.

In particular, the brand-new practical means have attracted everyone's attention.

Water can be electrolyzed, but what about other liquids? Oil, alcohol, vinegar, salt water, or sulfuric acid, nitric acid, there are certainly more interesting discoveries.

The battery used in this project is a rudimentary structure, and if a better battery can be made to provide more power, would the electrolysis of water produce more interesting results?

Zhang Hui designs a plan for himself in his mind, which is his field of expertise.

Two years ago, he discovered the element of ytterium, which was isolated from cupronickel, confirmed the chemical properties, and confirmed the spectrum of the new element using a beamsplitter.

When Zhang Hui saw his name on "Nature", he only felt that this was the most glorious moment of his life.

But in the time that followed, Zhang Hui found himself not only having to delve into new elements named after his own surname, identify compounds, communicate with other peers, participate in local chapter activities, and constantly study his heart papers to ensure that he could keep up with the trends.

But in the midst of his busyness, he suddenly found that his research on matter had fallen into a bottleneck, and he could never see a new result. And electrolysis, a new practical means, may be able to bring something new to itself.

Zhang Hui pondered, and it wasn't until the courtyard where he stayed that he came to his senses.

He asked his companion beside him, "Li Jiu, do you have anything to do in the afternoon?" ”

"I'm going to take a look at the exhibition in the West 13th Hall."

Zhang Hui flipped through the pamphlet in his hand and had an impression, "Hedong Military Hospital?!" I've heard it's scary. ”

The medical officers and medical students from Hedong are well-known among the people. The best surgery in the world, but also the protagonist of a horror story that dissects the living and the dead.

But as far as members of the Nature Society such as Zhang Hui are concerned, they are the main force of the paper of the Nature Medical Department, and the organs of the human body are dismantled one by one like parts of a dismantling machine, and then their function is confirmed one by one.

In the past, people in the world only knew that there were five internal organs, and there was a lot of speculation about the role of these internal organs. Through the efforts of the medical officers of the Hedong Military Hospital, the source has been gradually cleared up.

But in any case, at this conference, the human skeleton specimens and the specimens of the internal organs were brought for display, and Zhang Hui was still a little hairy.

Li Ying didn't care, "The bones grow in your body, but they are separated by a layer of flesh and skin, what is there to be afraid of?" Do you want to go along? He invited Zhang back.

Zhang thought about it and shook his head, "I want to try what effect salt water electrolysis can have." There should be a real device here, but it really can't be done, and it's too late to make it. ”

"Okay then." Li Ying didn't say much, and smiled.

There are so many interesting things here that you can't afford to delay for a moment.

Zhang Hui returned to the room and began to design his own real yàn.

It's been two days now.

For the environment here, Zhang Hui couldn't be more satisfied.

No matter food, clothing, housing and transportation, the arrangements are even better than imagined.

More importantly, they are all like-minded people who pursue the truth of nature.

The so-called talk and laughter have a great Confucianism, and there is no vain exchange. Zhang Hui couldn't talk much about Hongru, and when he was in the township, there weren't many like-minded companions.

But his neighbors here, his companions, all of them are devoted to learning from things.

When it comes to astronomy, I will not talk about the Tai Sui into the three walls, and the world will be in chaos, but will talk about the rings of Saturn, the craters of the moon, the sunspots, and how to better polish the lenses of telescopes.

Speaking of geography, we will not say that the back mountains and mountains have good feng shui and can produce noble people, but we will talk about the sediment deposits of the Yellow River, and we will talk about latitude, and we will discuss launching an expedition to the southern hemisphere.

When it comes to chemistry, no one will make a fuss about dissolved iron flakes with sulfuric acid, and when it comes to physics, no one will fail to explain the principle of rod scales.

For Zhang Hui, this is a paradise.

In the two days since he arrived in Beijing, he didn't even think to visit the famous seventy-two stores, take a look at the spring of Fanlou, and take a look at the state bridge.

How can there be that free time.

Don't see that? All the members who came to participate in this conference were in one exhibition hall after another, one after another, and in the discussions, they left the opulence and prosperity of Tokyo behind.

Although when they came to Beijing, they were entrusted with various purchase tasks by their families, relatives and friends in the village, and many people, after getting on the train, still wanted to visit Tokyo City in addition to the meeting, and now they have no time to think about those things.

Although he couldn't live with a few fellow villagers in Yanzhou - Zhang Hui had made an appointment with them to set off together, and even bought the ticket, but he had to postpone it for a few days because of a sudden incident at home - but it also made him meet Wei Pu and Li Ying.

Although Li Ying was born in a wealthy family, he did not have the arrogance of a rich child, and he was like-minded with Zhang Hui. And Wei Pu is an old friend of the privy council Shen Kuo, although he is still white, he can speak in front of Pingzhang.

Li Ying is good at mathematics, so he also pulled Zhang Hui to ask Wei Pu for advice in the past two days. Although he didn't have the heart to cling, he was able to get to know Su Pingzhang, Han Xianggong, and Shen Shumi, who were the objects he admired, and Zhang Hui couldn't help but feel excited.

But...... Zhang Hui suddenly discovered.

Among the three Zaifu and the four councilors of the Liege Society, only Prime Minister Han Gang has not yet come.

I heard that he was busy preparing for the Great Council, and he didn't know when he would be free.

However, as the prime minister who deals with the world's major policies, it is natural to be busy.

……………………

"Yukun, aren't you busy?"

Han Gang was closing his eyes to recuperate, and when he heard Zhang Dian's voice, he had to open his eyes.

"Brother Zihou, I don't know what's going on?"

"Lu Jifu has something, I don't know if you have heard of Yukun?"

"What's the matter?"

Zhang Dian is like a middle-aged woman, talking about other people's gossip, maybe there is some element of schadenfreude, "Yu Zhong and the daughter of Lu Huiqing's family are reconciled and separated." ”

Han Gang blinked, "Really?" ”

Yu Zhong is the champion of Han Gang's department, but his character is not taken by Han Gang. It's not that he's bad, it's just that he's not a journeyman.

Since the top student in high school, Yu Zhong married Lu Huiqing's daughter.

Speaking of which, in the sixth year of Xining, although Lu Huiqing was not yet in a high position, he was already the core of the hot new party. Investing in him, in the eyes of many people at that time, was a good deal with a lot of profits, if it weren't for Yu Zhong's top student, he wouldn't have gotten this opportunity.

It's a pity that Lu Huiqing's scenery has only been for a few years, especially after he has been in power backwards, Lu Huiqing has no chance to get ahead, and has been pressed outside the capital by the Zaifu.

It is not only Lu Huiqing himself who has been suppressed. His brothers, his kinsmen, and his henchmen were similarly suppressed visibly and invisibly. With Lu Shengqing's qualifications, he could have already been promoted to the ranks of politics, but who made him Lu Huiqing's brother.

Yu Zhong is Lu Huiqing's son-in-law, although he is the top of the list, but he can only sigh obediently, in this subject of Xining's six years, among the first-class and second-class jinshi, Yu Zhong's progress speed is very low, Han Gang can't compare, but the five, six, seven, and eight in the same year can't be compared, so it can't be said.

A top leader, as soon as he enters the official, he is a Beijing official, no more than other people in the same column, but also to enter the curtain first, and then after two terms and four transfers, three terms and six transfers, before he has the opportunity to become an official. It is equivalent to the beginning of Shi Brown's entry into the official, Zhuang Yuanlang has five to ten years less grinding than ordinary Jinshi, and in the process of promotion, Zhuang Yuanlang has taken a different route from ordinary Jinshi, with faster speed and more classes.

Xining three years Gengxu Branch has two politicians, the champion Ye Zuqia is one of them, after Xining six years out of Han Gang, although there is no politics, but there are several of them, and it is only one step away from the politics. The Jinshi in the ninth year of Xining and the Yuanfeng period also caught up behind, among which Zong Ze, who was regarded as a new star, was promoted to politics only in three years.

Yu Zhonghui thinks that he has been implicated by Lu Huiqing, which is also reasonable. But Yu Zhonghui chose to break with Lu Huiqing in this way, which is quite unexpected.

Zhang Dian glanced at Han Gang and asked, "Yukun, you shouldn't like Yu Zhong's approach, right?" ”

Han Gang shook his head, he really didn't like it, even when he was fighting with Wang Anshi internally and externally and tossing the court, he didn't say that he would go home and be angry with Wang Yi.

It's okay to put the blame on Lu Huiqing. In the eyes of Han Gang and Zhang Dan, Yu Zhong is the backbone of the Lu Party, and of course he has to press the local government to the death.

But using divorce as a solution to the problem has no ability, and it has no taste. Yu Zhong didn't nod his head at the beginning, could Lu Huiqing still marry his daughter? Make your own decisions, and you should bear the consequences.

"In the past, there were people who killed their wives and asked for generals, and now there are people who abandon their wives and ask for their faces." Han Gang smiled slightly, "We can't afford to use this person." ”

"Then let's change places for him." Zhang Dian said, "By the way, help Lu Jifu vent his anger." ”

Fight with Lu Huiqing, but Zhang Dian has always regarded Lu Huiqing as an equal opponent, which is not something that juniors like Yu Zhong can bully.

"Where?"

"Just go to that military state in Jiangnan, don't rely on the sea or waterway."

Frontier lands, ports, or transportation arteries are all places where you can make a difference. If you want to abolish a person and directly get a quiet Shangzhou, this is the easiest and most uncriticizable way.

Han Gang nodded, "Let's see if there is anything missing in two days." ”

"Still out of town?"

"Don't worry." Han Gang said with a smile.
