When Chen Youjia returned home, the room was only slightly lit. www.biquge.info She thought that Wang Qi was not there—the teacher's accommodation was much better than that of exchange students, so she would naturally choose to live here, and she pushed the door straight.

Then, she was blocked by a fine net.

If you look closely, this is a three-dimensional web, each node is a small sphere, and there are many small black lines connected to each other between the nodes. These black wires are taut and form a delicate structural part. These structures are still changing.

And in the center of this fine three-dimensional net, Wang Qi was happily flipping through the book, he turned a few pages, his fingers waved twice in the air, and then, the structure of the black grid also changed.

The faint aura he had in his hand illuminated the room. This light was even weaker than the faint polar sunlight outside the house, so Chen Youjia thought that there was no one in the house.

"What are you doing?" Chen Youjia furrowed his good-looking eyebrows and took a half step back.

If this net is the arithmetic problem that Wang Qi is doing, she will not be able to touch it.

Only then did Wang Qi realize that Chen Youjia had come. He commanded, "Jarvis, storage structure." A few seconds later, the black network collapsed, and then turned into a fluid, converging into several finger-thick black streams of water, which merged into Wang Qi's clothes.

"Today I met a monk from the Burning Gold Valley who was willing to cooperate. Wang Qi was very happy: "Although the cooperation will not be too long, I can definitely complete the initial content." ”

"That Grandmaster is also pitiful, and he actually invited such a scourge to you. Chen Youjia said very seriously: "Don't develop any strange poisons." ”

The last time Wang Qi joined the Empirical Department was in Shenjing, at the invitation of Tatsukaze. At that time, Chen Feng wanted to prove that "being a good person is good", and when it was implemented, he set his sights on the unfamiliar direction of "Shinto", and Wang Qi made a physical demon curse on the basis of Chen Feng's research, which is a physical thing that destroys human nature. Now that I think about it, this is a bolt from the blue for Chenfeng.

If Wang Qi had invested in the Empirical Department of the Burning Gold Valley, he might have developed something that would be a strange poison.

"Metal, crystal. Wang Qi said dissatisfiedly: "Why do you think this field is related to the development of poisons?"

"Metal ** is a strange poison, and poisons can also crystallize. ”

"You have a good and reasonable point...... Wang Qi sighed deeply: "I am moved......"

Chen Youjia rolled his eyes, ignoring his tricks, and asked instead, "Is there any progress?"

"Well, it's amazing. Talking about this, Wang Qi immediately became interested: "About the molecular structure...... You know what determines the nature of molecules, right?"

The chemical form of a molecule is determined by the structure of the molecule itself. Simple small molecules, with only a few atoms, can change in a limited range, and can't play too many tricks. But macromolecules are different.

For example, many of the famous flowers of the Rosaceae order have an attractive fragrance from a substance called "citronellol", which comes from the geometry of the substance with ten carbon atoms as the skeleton, hydrogen and oxygen as flesh and blood, and the chemical bonds between the atoms. However, the difference between the left-handed and right-handed carbon atoms causes a difference of more than 100 degrees Celsius between the boiling point of L-citronellol and D-citronellol.

Crystals are no exception. The strange order of a crystal comes from the orderly arrangement of the molecules inside it. A set of basis vectors corresponding to three-dimensional periodicity and unit cells can always be found in any crystal. Each unit cell is like a regular lattice, forming an orderly whole with its other units in six directions, up, down, left, right, front and back. If each unit cell is reduced to a particle, then the strange network of particles should be a tight grid.

-- Yes.

"I thought that if it was a crystal, it must be long-range orderly. As long as it is long-term orderly, it will inevitably be able to be dealt with by group theory. Wang Qi said: "But now it seems that I think more simply. ”

Long-range ordering is a concept relative to short-range ordering. This is said to be a single crystal, where all the molecules are ordered, periodic, and all arranged together in a tight form. Short-range ordering, on the other hand, does not have this characteristic. For quasicrystals or amorphous molecules with "short-range ordering", some molecules may exhibit a high degree of order locally, but this order will only stay in one locality.

This is on Earth. In China, it's a little more complicated. In the aura environment, there are more forms of physical bonds between atoms, which can contain more and even changing internal energy. And the crystal structure is also, some structures can only appear under the support of strong spiritual power, and the molecular structure of these spiritual power will disintegrate if it is extracted. There are also structures that are constantly changing in cycles.

This makes the study of crystals a mess.

Chen Youjia didn't understand the truth for a while: "Long-term orderly...... Group Theory ......"

"Periodicity means symmetry. Changing the sky. Wang Qi explained: "Long-range orderedness means that there is always complex periodicity inside the crystal, which means that there is symmetry. Group theory is the study of 'symmetrical' changes. ”

Chen Youjia asked unceremoniously: "It doesn't seem that this is a particularly difficult thing, why didn't anyone think of it before?"

"It's strange that no one thinks of something so obvious. Wang Qi grinned: "It's just that the arithmetic level of the people who invested in this field before is far inferior to me!"

With Wang Qi's daily hard study and research, his arithmetic level has also risen. Now not to mention the arithmetic logic that he was originally good at, even if it is topology and group theory, he can be called a first-class grandmaster.

When he said this, he really didn't need to blush.

"But you don't look like that stinky. Chen Youjia pointed out the core point: "You should have encountered a problem." ”

"I still need some time to continue to do a little empirical evidence and deepen my accumulation. Wang Qi sighed: "I can make some things, but that can't be called 'progress'." ”

Now the reason why Burning Gold Valley laments that crystals are difficult to make is because the mathematical tools are not developed enough, and the tools for seeking the Tao are not sharp enough.

It's fine to depict simple crystals according to the conventional group theory, but once it comes to heaven and earth, the periodicity of crystals will become extremely complex, and many monks in the Burning Gold Valley have found that this thing is not intuitive at all, it is difficult for people to form intuitive imagination, and it is full of all kinds of changes, so complex that it takes a lot of effort just to understand.

For the monks of the Burning Gold Valley, this is tantamount to losing the first step, losing at the starting line. When you understand the theory, it takes a lot of effort to construct the intuitive impression of that crystal in your head, so how do you think about it?

Like the Unification Alliance, the Burning Gold Valley is also eager for collaborators with a high level of arithmetic.

Chen Youjia sat down beside Wang Qi: "Oh. ”

"However, it is precisely because of this that this question is valuable!" Wang Qi said excitedly: "If it is a simple problem that can be solved by any cat or dog as long as it is an idea, then what is the meaning?"

"Oh. Chen Youjia leaned on Wang Qi. For Wang Qi's look, she has long been surprised. Even when Wang Qi said that she wanted to study the way of physical nature, she saw this scene.

It's as if you've received a revelation from the future.

"Looks like you're tired......" Wang Qi hugged Chen Youjia.

"I'm tired. Chen Youjia sighed: "I can't beat the demon clan to get angry......"

Except for Wang Qi's group, the strength of the other classes, the demon clan instructor and the human race instructor are much higher than the students. The minimum standard of the lecturer is "just enough to suppress the joint attack of all the students". But in this case, the teachers themselves are embarrassed to fight with the students - except for Wang Qi.

"What are you angry about? Which demon clan?" Wang Qi pondered: "It just so happens that I have some new ideas for studying the demon clan's Shinto cultivation method, and I want to give it a try......

"Come on, I can't beat you, but I can crush twenty or thirty strong people I have teamed up with, and they are definitely stronger than you. Chen Youjia rubbed on Wang Qi's shoulder, and at the same time held a notebook in his hand: "Today's notes, copy ......"

Like Chen Feng, Chen Youjia also followed the update demon clan to learn the knowledge of Shinto - in the Shenjing incident back then, she was an accomplice, and she was a big sinner who helped Qi to abuse, and in the eyes of the high-level of the Immortal League, she was also a good hand at Shinto.

In fact, it was precisely because of this that Wang Qi asked Chen Youjia to take notes. Many of Chen Youjia's concepts in the way of the gods come from Chen Feng and Ai Qinglan. At this point, it is considered "in the same vein" as Wang Qi. And Chen Youjia's arithmetic thinking was also deeply influenced by Wang Qi. For Wang Qi, Chen Youjia's notes have high research value.

"Well, that's pretty much it. Wang Qi nodded: "I'll go back to Shenjing in a few days to verify a little something." That's enough. ”

Chen Youjia sighed lightly: "You have studied enough things recently...... Demon Shinto Method, Beast Mechanism Control Method, Crystal, and Arithmetic of Your Own Job...... Can you keep up?"

"I don't feel like I'm being distracted at all. Wang Qi said: "This is a matter of the same field." ”

All of Wang Qi's research is run through by a core. Whether it is the control of the beast mechanism, or the crystal, or the demon clan Shinto method, it is all extended by this core.

"By the way, I'm going to go back to Wanfa Gate by the way to see the progress of Wei Cang's research-will you go back with me?"

- Wanfa Gate......

Chen Youjia suddenly felt weak for no reason, and shook his head like a rabbit. (To be continued.) )
