Last time, it was said that Lu Ya'er's real yàn room recruited some staff, which caused the students of the magic department of the Creation School Park to sign up enthusiastically, and even some students from other departments were eager to try.

"In today's lesson, we're going to talk about redox reactions. As we all know, combustion is a typical oxidation reaction, and generally speaking, the substances in this reaction are composed of combustible substances and oxygen. However, there are special cases where oxygen is not required for combustion. For example, the strong reaction of hydrogen in chlorine is a typical combustion phenomenon. In a huge classroom, Lu Ya'er explained her new theory to a large group of students.

"Here I want to redefine the meaning of oxidation reaction. In the previous chapter, we learned about the valency of an element and understood that the valency of an element will inevitably change in the process of a chemical reaction. The so-called redox reaction refers to a type of reaction in which the valency of an element changes before and after a chemical reaction. All elements with reduced valency are called reducing agents. On the other hand, all elements with elevated valency are called oxidants..."

While the students carefully recorded the lecture notes on the blackboard, a group of older professors in the middle of the front row stood out. After seeing Professor Lolita's lecture notes through various channels, all the professors of the Department of Magic couldn't sit still, believing that Professor Lolita's "The Molecular Basis of Magical Elements" broke through the shackles of existing magical research, was incomparably forward-looking and breakthrough, and could become an epoch-making theory. In order to fully and thoroughly understand Professor Lolita's theory, the professors gathered in Professor Lolita's class.

After talking all morning and completely explaining her theory of redox reaction, Lu Ya'er closed the handout and hugged Xiao Mingyue to prepare to return to her small villa to rest, and by the way, she taught some new magical knowledge to the two personal disciples, Enleko and Bertina.

"Professor Lolita, may I ask you a few questions?" A handsome middle-aged uncle with a beard led a group of professors to stand up and prepare to ask questions, which stopped the students who were about to leave.

"Dear Professor Lorenz, you are an expert in elemental magic and a great alchemist, and you can ask me at any time if you have any questions. I will know everything, and I will say everything. Lu Ya'er replied modestly.

"You're so kind, Professor Lolita. I have just listened to your wonderful lecture, and I have benefited a lot, and at the same time, I have thought a lot about it. From ancient times to the present, magicians have extracted a variety of about tens of thousands of different substances in the real yàn room, and studied the properties of these substances in detail. Now you've reclassified these substances. It is divided into compounds and elementals. The compounds are made up of various elements, and their properties are very different from those of the material. Now what I want to know most is how you came up with the idea to define so many compounds in this very epoch-making way? Professor Lorenz asked sincerely, a charming smile on his face.

"The question is very interesting, it reminds me of a dream I had when I was a child. In my hometown, boys and girls don't usually play together. When they were separated, the boys were very aggressive. Loves to play some wild games. Girls, on the other hand, would rather waste their time on things like embroidery and painting than go out of the room to unleash their youthful energy. Once, when I was dreaming, I dreamed that the boys and girls grew up and formed their own families. Then the men and women who are family units take on a different look from their childhood. At that time, I was so young that I couldn't imagine how people would change when they grew up. At that time, I simply thought that a man and a woman with a single attribute would change their own attributes when they were combined with each other..."

At the same time, Yang Liu, who was far away from time and space, was sitting on the bus returning to the team with Long Yu. Prior to this, Yang Liu used the holiday to record his new album, which sparked another round of fans after it was released. Because the songs selected by Yang Liu are all before the era of intercolonization of the blue mother star. The classic songs after the unification of the Chinese nation into the world, full of retro tunes and modern elements, are very in line with the appetite of contemporary young people, and the sales volume has reached a new high, and at the same time, the popularity of Yang Liu has been pushed to the ranks of first-class singers.

"Liu Liu, did you say that the superiors hastily recalled us back to China this time, because of a series of victories we have achieved in Russia?" Long Yu guessed.

"That's certainly one of the reasons, but it's certainly not the point. After all, our role in remaining in Russia is much greater. This time, my superiors summoned us back, and I think there must be a more important task for us. Yang Liu analyzes all kinds of possibilities.

"The more important task, unless it's a fight with the Americans. What other country in the world could be more powerful than Russia's air force? Long Yu was developed by Yang Liu's speculation, and his mind was opened.

"Little junior sister, you have a point. But we are now one of the largest countries in the world. I am afraid that competing with others in such a small field will lose the bearing of a great country. Besides, as everyone knows, our country's air force has a certain gap with the United States in terms of weaponry and personnel training level, and temporary victories are often regarded by other countries as occasional flukes. Therefore, it is not very likely that the higher authorities will give us such a task. Yang Liu continued to analyze.

"Since we weren't asked to slap the Americans in the face, I guess it's probably because the top of us both took a fancy to the physique. You want to catch us as astronauts? After all, I am afraid that it will not be the two of us to fly a reconnaissance plane to the skies over US territory to provoke such a mission. If it weren't for the last time we overheard the conversation between the chiefs, we wouldn't know how to use the storage zài of such a group of mysterious guys! Long Yu sighed. Last time, Long Yu and Yang Liu secretly flew out of the air base and wandered around, and accidentally learned that our country was also conducting strategic reconnaissance in the skies over the United States. The difference is that our country has always carried out similar tasks in a low-key manner, and the ordinary indignant youth can neither understand nor taste the indescribable pleasure from it.

"In fact, the military temptations between countries have never stopped. It's just that ordinary people don't know. In fact, it is not good for the people to know too much, and it is not easy for the country to grasp the direction of public opinion. Yang Liu expressed his opinion.

"Liuliu, you are talking more and more like a national leader now. It seems that you never worried that our country would be completely contained by the West? Long Yu asked curiously.

"Little junior sister, don't you think that Chinese are generally smarter than foreigners?" Yang Liu asked rhetorically with interest.

"Is it smarter than a foreign country? Why didn't I feel it? Among the foreigners we come into contact with, there are many smart ones! Long Yuhu asked suspiciously.

"That's because the foreigners you're dealing with are all mermaid school students. All of them were born in the upper class of the United States, and they were all so-called elites in the future? If such people are not smart, I am afraid that the United States will be doomed within a hundred years. Yang Liu said disapprovingly.

"Then Liuliu, who are you comparing to? Are they the workers and peasants, who make up the largest proportion of the population of society? Long Yu asked curiously.

"That's right," Yang Liu nodded in agreement, "If you find an ordinary person on the street in China and the United States for an interview, if you ask him his opinion on the price of oil oil, the Chinese, whether the answer is correct or not, will always give a large number of answers." Most Americans, on the other hand, can't say why. ”

"This scenario is possible. Americans tend not to care about politics, they are usually only interested in basketball games, football games and soap operas, and the biggest political issue they usually care about is the election of the president. But that doesn't mean that Americans are dumber than Chinese, right? As the counterparty, Long Yu tried his best to express doubts.

"It's not that Americans aren't interested in politics, it's that they have barriers to accessing relevant information. For example, the names of countries and places in many countries are a long list of incomprehensible letters, and they read international news full of new words, preferring to watch soap operas. Yang Liu gave an example.

"Then the Chinese don't have this obstacle? Let me think about it, Liu Liu, you must want to say that it is the reason for the Chinese characters, right? Ordinary Chinese have no obstacle to reading thousands of Chinese characters. In addition, Chinese characters can be used to make sense of the text, and ordinary unfamiliar words generally do not become an obstacle to the reading of ordinary people. I roughly understand what you mean. But this can only say that the Chinese have a certain advantage in reading. If this advantage is erased, I believe that the Americans will be as smart as the Chinese. Long Yu continued to mess around. Similar debates between the two have occurred from time to time. No matter who is the opposite, always try their best to find loopholes in the other side's point of view.

"It's impossible to wipe out this assumption of superiority, unless Americans also learn Chinese. In fact, due to the progress of science and technology, various professional vocabulary continues to emerge, and English, an alphabet-based language, is increasingly unable to carry a large number of new vocabulary, so that experts from all walks of life are always busy reciting professional English words, otherwise they will not be able to gain a foothold in the industry... You know, the history of the blue parent star has proven my point..."

"Report!" "Please come in."

Yang Liu and Long Yu walked into the commander's office with neat steps.

"Welcome back to the team, Comrade Yang Liu, Comrade Long Yu. In view of your excellent performance in Russia, I present it to you on behalf of my superiors..."The commander and political commissar gave Yang Liu and Long Yu a warm praise and self-praise, as if the two of them single-handedly killed Lao Maozi's entire air force flying regiment.

Finally, the commander pointed to the middle-aged soldier who had been sitting next to him and smiled silently, and introduced: "This is from the Space Agency..." )
