"What is a field?"

On the podium, the gray-haired martial arts theory teacher was taking a class called "Field Theory".

After speaking, he pointed at Yan Ying and said, "This classmate, you answer." ”

This old sect's cultivation is not high, only Wu Zong's cultivation, but his own research in the field of "field" belongs to a relatively new field in Shengguo, and this person can be said to be the only "expert" in this field.

Although the cultivation of the class such as Li Wuxian and Yan Ying was higher than him, no one despised his class, because several of the students of this old sect were all Great Martial Sects, and even his ancestors had two demigods. It's just that I don't know why the family was lonely in the end.

Yan Ying stood up and said, "Teacher Hui, field is a form of material existence, a kind of domain collection of the basic characteristics of matter. ”

"Well, that's right, student Yan Ying, sit down. ”

The old teacher nodded gently and said, "You can understand the original concept to this extent, which is very good for a freshman, but it is not so much a domain set as a set with domain characteristics. Although it is one word missing, the meaning is not the same. ”

"Squeak", his Yuzhu charcoal pen drew two circular structures on the black lecture board, and said:

"Suppose this is a Shenwu particle, the field of Shenwu particles—"

He drew a circle of dotted lines with a starting end and a closing end around the two models of Shenwu particles, "What do you find them look like?"

One student said, "Magnetic field, electric field." ”

Jiao Xi was very pleased: "That's right, the field of Shenwu particles is very similar to the magnetic field and the electric field, they both have a range, in this range, their action gradually becomes weaker according to the change of spatial distance. ”

"And what we're talking about today isn't this, we need to know, what is the field of Shenwu particles?"

"It's a unique energy that can pass through the boundary wall, just as electric and magnetic fields can pass through wooden planks, and the field of Shenwu particles can pass through most of the matter you know, and that makes it able to travel through space. ”

Next, the teacher talked eloquently......

Li Wuxian listened to the lecture carefully, he had practical experience in martial arts, but Lieutenant General Shenwu Xing studied martial arts very thoroughly and put forward various model theories, which benefited him a lot.

At present, this class of "Field Theory" is about the problem he is concerned about - the field.

Of course, this teaching himself is only a martial artist, and he can't even understand the essence of the realm at all, but Li Wuxian discovered the relationship between Shenwu particles and fields from the field theory he studied.

"Field, Space...... It seems that there is some connection between the two!" Li Wuxian thought for a moment, under the table, his little finger turned into a point of light for a while, and then gathered into a little finger, it was he who was testing the Shenwu particles.

He even vaguely felt that his grasp of the field had reached a new level, and this teaching did not realize how practical the field he was studying.

After a class, the teacher coughed a few times, bowed to everyone, and left with his textbook.

Li Wuxian had a little doubt about a few knowledge points, he had also gone to the library of the school palace to check before, but he didn't find the answer, it just so happened that this teacher seemed to be very researched about this area, so he followed, ready to ask clearly.

That old teacher is obviously not small everywhere, he looks like he is eighty or ninety years old, although he is a martial arts sect, it is undeniable that he is going downhill, and because he is biased towards theoretical research, his martial arts combat effectiveness is not high.

Li Wuxian even followed him all the time, and he didn't notice it.

After passing through a oleander forest with fiery red petals, Li Wuxian took a flash step and moved to a few hundred meters in front of the teaching, ready to pretend to meet by chance and discuss a few words with the teaching.

Unexpectedly, at this time, a middle-aged man from the realm of the Great Martial Sect stopped the teaching.

"Ahh......h Hello, the famous Zheng Jiaoxi of the Empire? ”

"Ah," the teacher was stunned for a moment, and then a trace of panic flashed on his face, he looked left and right, and then fixed his mind, "Mr. Huang, it's just an academic dispute, why be aggressive?"

"Academic battles, of course, I know. The one who was called Mr. Huang said: "However, the martial arts theory you published was rejected by the research society, so you lost the previous bet, I remember it seems to be 100,000 star coins! I don't know how you are going to pay it back, if you can't afford it, then your daughter's side, I am ready to ask her for some interest." ”

Zheng Jiaoxi's face was red and white, paused, and said, "I'll pay you back as soon as possible." ”

Mr. Huang said: "In addition, you have to publish an apology, saying that your field theory is a mess, and the field of Shenwu particles is just its gravitational force itself, and has nothing to do with Jiebi!"

"How is that possible, if the Shenwu particles have nothing to do with the realm, then the demon clan ......" Zheng Jiaoxi seemed to want to refute something at the moment, but Mr. Huang just looked at him with a smile.

"Think twice, Zheng Jiaoxi, stubbornness will not end well. You don't want to be so mixed up that you can't even teach!" Mr. Huang sarcastically said.

Zheng Jiaoxi seemed to be deflated, and said, "I will apologize!" As he spoke, he lowered his head and left in a gloomy manner.

encountered such a thing, Li Wuxian did not show up for a while.

A few days later, he asked others about Zheng Jiaoxi's affairs in the hall, and found that Zheng Jiaoxi was originally teaching in the State School Palace, because he was not good at making contacts, and his qualifications were not high, so he was gradually squeezed out by others and fell to the Fuxue Palace.

Even, because he insisted on his own field theory, he offended many people, because it is now popular to say that the field of Shenwu particles is only its gravitational force with fusion characteristics, not the field of electric and magnetic fields.

And the martial artist surnamed Huang who was embarrassed by Zheng Jiaoxi, Li Wuxian also inquired, this person is not

"The divergence between the mainstream and the emerging theories," Li Wuxian said in his heart, but according to his practical experience, he felt that Zheng Jiaoxi's theory was likely to be correct.

In the next few days, Li Wuxian took some courses in a row, such as "The Theory of Killing", "The Relationship between the Profession and Attributes of Martial Artists", "The General History of Shenwu Xing", "The Origin of Demons and Demons", etc., but the gains were not big, except for the theory of killing that allowed him to consolidate what he had learned before, the rest were lackluster.

Finally, it was time for the "Field Theory" class that he was interested in, but this time, Zheng Jiaoxi did not come.

Li Wuxian went back to his residence sullenly, and after meditating for a while, he felt uneasy, and asked someone to ask where Zheng Jiaoxi lived.

After arriving at the residence, he was told that Zheng Jiaoxi had resigned and should not teach.

Li Wuxian felt that it was a pity, and not long after learning that Zheng Jiaoxi had just left his residence, Li Wuxian thought about it and flew over along the path to the Cangshan School Palace.

In Li Wuxian's opinion, this person may have taken refuge, so it is impossible to take the big road.

Sure enough, after spending a cup of tea, Li Wuxian, after Qihua, flew to the vicinity of a small mountain peak, but saw Zheng Jiaoxi being pinched by the neck and leaning against the mountain wall.

And at the feet of Zheng Jiaoxi, a poor little girl, only twelve or thirteen years old, was kneeling on the ground and begging.

"Please, let my daddy go. ”

Her voice was hoarse, and she had obviously been pleading for a long time.

Li Wuxian didn't expect that the former teacher of the Academy Palace could be treated like this, and there was no guard on the side of the Academy Palace to take care of this matter.

Mr. Huang, who I saw that day, and the two burly martial arts masters, were "following the temptation" and said: "Zheng Jiaoxi, I think you can't afford to pay back this money, why don't you let your daughter go with us, don't worry, we won't treat her ...... badly."

"I'm a teacher from the Imperial Academy, you can't do this to me!" Zheng Jiaoxi's old face turned red and said.

Mr. Huang laughed: "What is a third-order teaching in the Cangshan Academy Palace, not to mention that the Academy Palace has already dismissed you, right?"

When Li Wuxian heard this, his mind moved, and the Shenwu particles immediately converged and became a human form, and his body appeared in front of everyone with a buzz, and the figures of those people were shaken away.

Several people were shocked, and when they saw that Li Wuxian's cultivation was nothing more than a "Great Martial Sect", they calmed down again.

Mr. Huang scolded: "Where did you come from? We are doing things for the Lei family, get out of here if you know each other!"

Li Wuxian didn't hear the shouts of these people at all, but smiled at Zheng Jiaoxi, hugged his fists and said:

"Student Li Wuxian, have you seen the teaching! Do you want the student to help the teacher kill someone?"
