As he spoke, all three walked in. Lin Yufei hurriedly got up. Today, Yun Huan and Zhang Zhongjian both changed into gray suits, with a brass compass in Yun Huan's hand, and two modern feng shui masters were alive, while Xinlan was still dressed as her, with a long sword diagonally behind her back. Lin Yufei was a little stunned, but Ye Fei laughed honestly and unceremoniously: "Senior brother, what kind of outfit are you and the teacher?"

"We are going to walk all over the street, and the junior sister refuses to change her outfits, so the two of us can hide it like this," Zhang Zhongjian said with a smile, "The teacher also started a feng shui master's business by the way." ”

"Did you find anything?" Lin Yufei asked on the side.

"There are two or three little demons, and the junior sister will solve it casually," Zhang Zhongjian said, "By the way, Senior Brother Lin, aren't there still people in your family, who came out again so soon?

"My sister is the only one in the family, and I went to school today. As for work," Lin Yufei smiled bitterly, "I was dismissed, just before I came." So now, I'm a vagrant. ”

"It doesn't matter if you don't have a job, I'll go back and say to my dad, come to my company to do it, anyway, it's not far for you to come to T City." Ye Fei interjected on the side, "Let's sit down first, I and the second senior brother just said that among these people, the two of us are still in a state of confusion." ”

"That's right," Yun Huan said, "Now that you senior brothers are here, we really need to let you have a handover of the situation of our group of people first." Sit down, Xinlan, it's important to get down to business. ”

Lin Yufei realized that from the moment he entered the door to the present, Xinlan's eyes had always been on him, and he looked eager to try. Lin Yufei was a little confused, it is said that this senior sister can be regarded as an outstanding beauty no matter how she looks at it, even if she looks at it a few more times, it is normal. But although he is quite tall, he looks really average, not as good as Ye Fei on the side, I don't know what the general appearance of the senior sister is. But I couldn't keep staring back, so I had to pretend to be blind and go down to sit down.

"People like us, both at home and abroad, have a long history," Yun also watched the crowd sit still, and said, "There are not many such people, but they exist in almost every era and place. It is called differently everywhere, but this branch in our country is called stargazers. ”

"Stargazers?" Lin Yufei subconsciously repeated.

"Yes. Legend has it that there was a secret book among stargazers, which once recorded such a legend: the first conceptual ability in history was obtained when looking up at the stars, so it was called. Who exactly this person is, and when he gained the power of concept, is recorded in the secret texts. Unfortunately, the Secret Book is said to have been lost more than 3,000 years ago, so we have no way of knowing, and many stargazers' predecessors speculated that this first person was probably the legendary Fuxi. ”

"Fu Xi's Clan, it's really famous," Ye Fei muttered, and then raised his hand: "Teacher, what is that conceptual ability?"

"Conceptual competence is the highest level of competence, also known as the ability of rules. Reaching this level of competence theoretically becomes a rule that cannot be changed as long as there is a basis to support its existence. In fact, there is no such thing as a truly complete conceptual capability, and we will take fire as an example. The concept of fire is burning, and when the concept of combustion breaks out in its entirety, it is equivalent to burning becoming an absolute rule, and as long as the basis of its existence, that is, the substance that can be used for combustion, exists, this concept will continue forever. The concept, or rules, will not disappear until the basis available for burning disappears. In other words, if the concept of a complete fire really breaks out on Earth, then the burning cannot be stopped, at least until the Earth burns out. ”

"I can't understand," Ye Fei raised his hand again, "There must be a lot of non-combustible objects on the earth, but if it's just the concept of combustion, how can it be completely burned out?"

"When the teacher said the rules, I guess I mean the laws of physics. Lin Yufei interjected, "The non-combustible object we talk about in our cognition should only be that we can't make it burn, not that the substance itself is not combustible." If it is really combustion that reaches the level of physical law, there really should be no such thing as non-combustible in theory. ”

That's what it means. Yun also nodded, and did not continue until Ye Fei showed an expression of understanding.

"In fact, in the circle of the capable, the understanding of the ability is also quite confusing, especially before the emergence of modern civilization. It was not until after the so-called first industrial revolution in the Western countries that a systematic analysis and classification of capabilities began. In China, the time for the real emergence of the system of conceptual capabilities is more than 100 years at most, and there are finally some explanations for the source of conceptual capabilities. The most basic one is that all abilities that can reach the sub-conceptual level are not born on Earth. ”

"Not on Earth?" Lin Yufei reacted quickly, "Could it be the universe?"

"Secondary concepts?" Ye Fei also interjected.

"That's not wrong. Yun also nodded, and at the same time stretched out his hand to signal Ye Fei to be calm, "Regarding the generation of conceptual abilities, the most accepted theory is that all abilities that can reach the conceptual level are generated during the period between before and after the Big Bang of Creation and before the birth of life. Therefore, the most widely accepted classification of ability also comes from this. ”

In this hierarchical system, competencies are divided into five levels: root concept, secondary concept, derivative concept, non-conceptual strong ability and weak ability. According to the origin of the concepts I just mentioned, the concepts that were associated with the Big Bang and that may have existed before the Big Bang are called root concepts, the concepts that occurred after the Big Bang and before the emergence of stars are called secondary concepts, and the concepts that arise before the birth of stars and before the emergence of life—note that I am talking about life in the grand sense, not humans or humanoid lifeforms—are called derivative concepts. ”

"As for non-conceptual and weak abilities, they are completely dependent on the abilities of living beings. Because living beings cannot interfere with the basic rules of the universe, the abilities that are born from living beings cannot be called concepts. The classification of the two is based on the degree of interference with external objects, and the ability to interfere with the existence of external objects is collectively referred to as strong ability, and vice versa is weak ability. ”

"But there are two abilities that need special attention. One is fire. It is easy to juxtapose water and fire in our concept, but fire appeared almost at the same time as the Big Bang, so it is called the highest level of sub-concept, and even some sects in Western countries directly classify it as the root concept, but water only appeared when the stars appeared after the universe cooled, so it is an orthodox derivative concept, and there is a big difference between the two. The second concept is called seeing. ”

"See?" Lin Yufei and Ye Fei were stunned at the same time.

"For a long time, it was classified as a non-conceptual powerhouse, but it has always been questioned. Because the strength of the capabilities of different categories of abilities varies greatly, the confrontation between capabilities of the same scale, a higher level, can form an absolute interference, or even make it completely impossible to play. But seeing this ability, even the lowest level of the record will not be interfered with by any concept, not even the root concept. So in recent decades, we've moved from the ability to classify what we see to the level of root concept. The reason is simple, the ability that even the root concept cannot interfere with should not be produced in living beings, or more precisely, in living beings within this universe. But at the time of the Big Bang, there would certainly be no observers in the universe, and the concept of seeing would not have been generated, so there was only one possibility: this concept might have come from outside the universe, or even from life beyond the universe. ”

"Outside the universe or something...... This statement is so cool," Ye Fei applauded, "I feel like I listened to a popular science lecture." ”

"Capable people are also receiving scientific knowledge, so it is normal for us to rely on science for most of our understanding and analysis of ability. Yun also smiled slightly, and was about to say something more, when he suddenly stopped. A few seconds later, the doorbell rang.

"The takeaway has arrived," Ye Fei got up to open the door, and a few minutes later, the coffee table in front of everyone was full of all kinds of barbecue, so much that it was almost impossible to put down.

"Let's eat first, and then we'll talk about it when we're done. Yun returned the road.

The meal was eaten quickly, especially for two young people. They are all anxious to understand what they have and what they will face. Just ten minutes later, the coffee table was already in a mess. Ye Fei burped: "I'll clean this up later, teacher, you can continue to talk about it." ”

"You're in a hurry. Yun also smiled, "What I just talked about is the grading of ability, and then what I want to talk about is the strength of ability." ”

"Isn't the grading of ability based on intensity?" Ye Fei raised his hand and asked again.

"Of course not. As I said just now, high-level capabilities can interfere with low-level capabilities, but I didn't say that the strength of high-level capabilities must be higher than that of low-level capabilities, which involves the issue of capability scale. ”

"Scale?"

"Remember what I said at the beginning about the explanation of the concept? The complete concept of fire can burn everything it touches, but there have been countless people with fire abilities since ancient times, many of them have reached the conceptual level, and I have even seen one whose ability is extremely close to the root concept level, but the earth is still intact, do you know why?"

"Why?" Lin Yufei asked.

"Because of the scale. It can be said that all the conceptual abilities that we have discovered so far and those who have not discovered them can only be called fragments of concepts, and the larger the fragments are stronger, and the smaller ones are weaker, and the scale I am talking about is not the scale of the scope or quantity of the effect of the ability, but the scale of the size of the fragment. The lowest conceptual capabilities can interfere with non-conceptual capabilities, but to what extent they can interfere depends on the size of the scale. ”

"For example, the ability of Fuyu belongs to the fragments of creation. Creation is the highest level of root concept, so there is basically no ability to interfere with his creation, but he cannot create something beyond the norm, and the creation exists for a short time, which is the result of the scale of the conceptual fragment being too small and the intensity too low. Another example is your ability, Jing Hong. Yun also turned to Ye Fei, "Your ability is growth, and the level belongs to the concept of derivation, but after years of summarizing, people have found that the lower the level of ability, the higher the degree of completeness it can achieve, so the degree of completion that your ability can achieve will definitely exceed that of your senior brother." So you're going to have to work harder. ”

"Does this rule also apply to non-conceptual abilities?" Lin Yufei asked, "Doesn't that mean that it is easier for people with weak abilities to reach a higher scale?"

"In fact, almost all weak abilities have basically reached 100% completion when they are developed, and even those with strong abilities can almost reach 100% completion through a short period of exercise. "But this also means that the growth of these abilities is very low, and there is almost no growth potential for weak abilities and the like." You must know that the level of ability is fixed at the beginning of acquisition, but in terms of scale, that is, the size of ability fragments, because of the limited bearing strength of the life form itself, almost all abilities will not be too strong when they are first obtained. As the strength of the body continues to increase under the refinement of ability, the completion of ability can continue to increase. ”

"Then what level of ability is the Dao technique we cultivate?" Ye Fei raised his hand again and asked.

"Dao techniques, as well as all the cultivation methods created by human beings throughout the ages, are strictly independent of the five types of abilities. Since it is a person's cultivation of his own physical potential, he can only be classified as a strong ability at most. However, after this cultivation method reaches a certain level, it can basically use the ability of the concept level, at least it is also a derivative concept, such as the wind, fire and thunder techniques you cultivate, and the alchemy of the West can even use the creation and destruction of the root level to a certain extent, which makes it difficult to define its scale and level. If I have to say, this is a kind of ingenuity of human beings, or intelligent life, a technology that invokes the power of concepts in a special way. ”

"Okay, let's talk about it to you first, you digest it slowly, and we'll talk about the rest tomorrow. Yun also stretched his waist for a long time, and a gleam flashed in his eyes, "Jing Hong, let's put the things to clean up first, we have guests here." ”
