Chen Feng didn't expect that his application would come down so quickly. It seems that the name Wang Qi seems to have an extraordinary meaning at the top www.biquge.info.

Since the above requirements cannot be divulged, he prepared the content of the interview a day in advance and submitted it for review.

This time, the above reply was very fast, and the review was directly passed. Soon, he used Xue Bufan's large calculator to connect to the Ten Thousand Immortals Fantasy Realm.

"Yo man, how did you remember to give me a newsletter. A flirtatious and careless voice appeared, accompanied by some rustling sounds, as if something was being written on the other side.

Chen Feng said: "Wang Qi, do me a favor." I have a couple of things that I would like you to help me illustrate with arithmetic. ”

"Okay, okay. The pen over there paused for a moment, and then changed a piece of paper, and it could be heard that Wang Qi was indeed very busy now, "Hurry up, I'm really in a hurry now." ”

Tatsukaze sent over the image that had been prepared in the morning. This spirit rhino was obviously too big, and it was transmitted for several seconds.

Those were seven knots, all of which Boso had only figured out in the last few days. It could be seen that he was imitating the creatures that Ai Qinglan had carved out of the Essence molecules.

And it's actually a living essentia molecule as well.

After forming the first one, Bosso felt like he had an epiphany, and he became more and more comfortable with the virtual images. Ai Qinglan changed to some longer chains, but it didn't bother him.

This poet of the Wu nationality seems to have really found some abstract law.

And Chen Feng and Ai Qinglan believe that this is the hidden secret. If they can connect this complex knot with the Wu knotted rope notation method, and construct a new "language" based on the existing grammar of the Wu people, they can summarize a set of methods that can be used.

"Grammar" is the rules of language, and it is something that can be quantified.

Who knows, Wang Qi made a hesitant voice: "Why are you asking this?"

"These knots are the key parts of a large magic circle, this magic circle is very peculiar, all the parts are completed with knots, and the complex structure of the knots is knotted into a law seal, and the spiritual power flows. It's the equivalent of a strange sigil. However, I can conclude that the vast majority of runic knots are derived from these seven knots. Help me break it down, it would be nice if I could deduce the solution of other knots. In addition, there is a technique for tying knots......"

A few seconds later, Wang Qi's reply came. Due to the long distance, the delay of communication is now more than two seconds.

Wang Qi's frivolous tone finally brought a hint of solemnity: "What are you doing with people?

"It's not desperate. This is a Jigu mission. Tatsukaze replied quickly.

At this time, Wang Qi's tone showed a hint of helplessness: "Then you are looking for the wrong person." ”

"What ......" Chen Feng was very stunned. Wang Qi has always been arrogant [at least that's how he sees it], don't say that he understands a little, even if he really doesn't understand, he will hold on and not speak, and then go home and learn it himself and then pretend to be forced. Directly say something you don't understand like this...... It's the first time in my memory. He wondered, "It's just a knot......

Do you know what kind of research this is? If I can study knotting thoroughly, then I'll just get away with it. Do you think knotting is easy?" Wang Qi's tone was full of a sense of intellectual superiority.

Chen Feng had to shake his head honestly: "I don't know." At this time, Chen Feng received a communication from the Fantasy Realm - that is, he completely infiltrated the Fantasy Realm of Ten Thousand Immortals and communicated face-to-face.

Chen Feng glanced at his interface weakly. He wasn't sure if he had applied for permission to use the Phantom Realm Communications. However, when he clicked the consent option, he actually felt that his consciousness was detached from his senses and entered a new interface.

Wang Qi sat in front of him.

Wang Qi gestured with his hand, and a transparent curtain wall immediately appeared between the two - that is, a simple two-dimensional plane.

"There is a sub-discipline of arithmetic that specializes in knotting, called knotting. Wang Qi said: "From the perspective of topology, this is essentially the study of how to embed several rings into the three-phase real universe, and the kink cannot be formed in the plane of the two-phase ......."

With Wang Qi's narration, a line appears on the plane. The thread is constantly bending, changing its shape. However, it just can't form a ring without intersecting with itself.

- 2D is not complex enough.

"In a four-phase or higher space, any knot can be easily untied. ”

Suddenly, the line in front of Chen Feng changed, becoming like a scaffolding, intricate, and normal people couldn't see it clearly.

Chen Feng said loudly: "Hey...... What the hell are you doing?"

Wang Qi said: "Four phases." Considering that the average person can only know and understand the three-phase geometry, I used the three-phase projection of the four-phase geometry – it's a knot. Under the condition of three phases, this is a dead knot. ”

As he spoke, Wang Qi pushed and pulled the geometry with both hands, and then the entire geometry was divided into two halves.

- The fourth dimension is too open.

Chen Feng was dumbfounded: "Isn't it a dead knot?"

"This is the four phases. Wang Qi waved his hand and said, "I said, in the four-phase or higher-level space, any knot can be easily untied. Therefore, only three-phase topology will study this problem......"

At this time, Wang Qi finally noticed the abnormal delay in the communication. He frowned and said, "Where the hell are you, why is the Spirit Rhino Flow so small?"

"The secret location, and the connection with the Ten Thousand Immortals Fantasy Realm is very weak. Chen Feng replied casually, and then asked, "Let's talk about the problem." ”

"Have you ever heard of the Ponzi conjecture of the counter?"

Chen Feng nodded: "It is said to be one of the most difficult arithmetic problems. ”

In fact, a considerable part of this conjecture has been proven. One-phase, two-phase, high-phase. However, the three-phase and four-phase are not proven. Wang Qi replied: "The higher phase is more open, the lower phase is simple, and there is only a three-phase change, which is complex and closed, and lacks freedom." Your problem happens to be a three-phase one. ”

Chen Feng blinked: "It's difficult?"

"If all you ask is how to untie the knot, I'll give it to you in minutes. But it looks like this knot also has a spell effect...... Well, this should be looked at separately......"

"The rule between the knots, that's very important. Chenfeng reiterated again.

Wang Qi asked, "Can you give me the complete formation diagram?" With only seven cores, I can't tell you much. ”

Chen Feng thought for a moment: "Try to break it down into those simple twisted links on the kink table......"

"Yo, do you still know the kink table?" Wang Qi said, "However, that's impossible." This 'knot' is very complex, not just the kink, but also the structure of the chain link itself. If I don't know the actual meaning of the spell, if I don't know its foundation, there's nothing I can do. ”

Chen Feng was shocked. This guy actually directly said Bosso's judgment.

- Because the rope book should be basically straight, so as to ensure that the reading is smooth and does not cause confusion. However, your knots are different...... It is the whole rope coiled into an intricate knot, and such a knot clearly does not exist for people to read.

Could it be that arithmetic is really the "wisdom" that is universal to the whole universe?

"Hey, what do you want?" Wang Qi asked.

"I'll apply to the above. Now some of these things can't be passed on to the outside world. Chen Feng said: "But I still hope that you can give some analysis from the perspective of arithmetic." ”

"Oh. Wang Qi agreed, but he seemed careless, obviously thinking about other things. It took him a few seconds before he said, "I still have my own things to do, and I can't wholeheartedly help you do the analysis." ”

Chen Feng nodded: "Also, I would like to ask you to write a ...... A beginner's guide to algebraic topology. ”

Wang Qi's face was strange: "What, if I don't help you, you are ready to go on it yourself?"

Chen Feng smiled bitterly: "Lest I can't understand what you write in the end, right......?" I'm also going to do research on my side. ”

"Yes, yes. The analysis of the seven knots, and the introductory guide to algebraic topology, right?"

Chen Feng always felt that Wang Qi seemed to be very perfunctory.

..............................................................................................................................................................................................................................

On the second day, after the first arithmetic seminar of the famous "Foundation Building School" and today's "Foundation School" was over, Wang Qi greeted everyone: "Since it is called 'class', it must have the appearance of a 'class'. I assign a homework that everyone has to complete after class. ”

Everyone immediately sat upright.

Their hearts are still in a state of extreme shock. For Wang Qi's self-created arithmetic tool, and it is also the kind of arithmetic tool of great significance, they are already a five-body caster. Now each of them is in an abnormal euphoria.

Wang Qi said: "Since we are algebraic topology...... So be it, there is a small branch of algebraic topology called knot theory, and here I am, there are seven complex knots......" As he spoke, he waved his hands and conjured up seven extremely complex knots.

"You can choose any of these seven knots, study the commonalities of any of them, and use the knowledge of algebraic topology and the ideas I have given you to analyze their properties. Three days...... Forget it, ten days, a small essay. ”

Zhao Qingtan raised his hand and asked eagerly, "Do you need to use the idea of 'layer'?"

He really thought that Wang Qi wanted to improve everyone's level in this way.

Wang Qi pretended to be deep and muttered for a moment: "Feel free." ”

The most elite group of disciples from the Ten Thousand Methods Sect gasped and looked at those figures, eager to eat them whole. (To be continued.) )
