"Now science has concluded that the universe has 11 dimensions, we live in three-dimensional space, but human beings can only perceive the existence of a little four-dimensional space, as for other dimensions, it may be that it is "hidden" by itself, and human beings can't find it, just like human beings know the existence of ultrasonic and infrared rays, but they can't hear or see, and things that can't be detected are not necessarily non-existent, and there are too many fog-like existences in the universe. Human beings can only perceive the three-dimensional space they are in, as well as the low-dimensional space, for example, for ants, for them, the accurate is only two-dimensional space, because they have no height, maybe human beings are the same, there is no time that can be changed coordinates, maybe in the eyes of higher-dimensional creatures, human beings may be the same as ants. ”

"The 6th century B.C. to the 3rd century B.C. is now recognized as the "Axial Age" of human civilization, the first awakening of mankind. The spiritual culture created by rational thinking determines the cultural trend of all subsequent nations. In the world at that time, Laozi, Zhuangzi, Shakyamuni, Confucius, Socrates, Mozi, Plato, Aristotle and other talents came out in large numbers, stunning the contemporary, and the most typical phenomenon in our country is that the sons stand side by side, and a hundred schools of thought contend. Why so many outstanding figures appeared at the same time, and since then, there have been no glorious achievements in the past, until today there are different opinions, there is no definite conclusion, this point is worthy of our in-depth study and discussion. After Professor Li finished speaking, he took another sip of tea and looked at Wu Lang who was stunned with a smile.

"Professor Li, can you tell me about the eleven dimensions of the universe?" Wu Lang looked at Professor Li seriously.

Yes, the world we live in is constructed by three "dimensions", namely "length, width, and height", and "time", which is widely recognized as another dimension, is actually a pseudo-concept, and time essentially refers to the movement of objects, and cannot be supplemented into "dimensions". We know that one dimension is a point, and two dimensions are a line, but is there life on a line, or even civilization? Actually, this is very possible, just like the four-dimensional and five-dimensional life does not think that there will be life in the low-level three-dimensional space, but do we exist? Of course there is. So we haven't been able to confirm it, so it's too impatient and arrogant to assert that the low-dimensional space is a dead domain?"

Wu Lang then nodded, agreeing with Professor Li's statement.

For example, ants are "flat creatures" that cannot perceive heights, they only have the concept of front, back, left, right, and left, so wherever they go, it is like being on paper. So, are ants two-dimensional life? The answer is no, ants exist in our three-dimensional space, and they are naturally three-dimensional life forms. ”

"A two-dimensional life can never perceive the existence of height, just like we draw a small person on paper, no matter how much it tries to do it, it still can't break through to three dimensions, even if you fold the paper in half, make a cube, make a circle, it can still only move on the drawing paper, it is still a two-dimensional life. Since two-dimensional life can only move in a plane, the one-dimensional, which does not even have the concept of width, can only jump sideways from side to side repeatedly. Maybe one day, a one-dimensional life will wonder what the universe will look like after breaking through this line? Just as we who live in three dimensions will also fantasize about what the fourth dimension will look like in addition to the length, width and height? However, the development of science is always unpredictable, and as long as we abandon arrogance and stagger, fantasy will one day shine into reality. After Professor Li finished speaking, he made another pot of tea and refilled a cup for Wu Lang.

Wu Lang hurriedly held the teacup in both hands and said thank you repeatedly.

"Human beings now speculate that there should be seven levels of civilization in the universe: the first level of civilization, that is, the planetary civilization. Humanity has not reached this level, but it has been working hard to achieve a round trip between the Earth and the Moon, and between the moon and the major planets. But the round-trip between Earth and other planets such as Venus and Mars is not yet complete. So we can't travel freely between planets. Second-level civilizations, i.e., stellar civilizations. In the solar system, we know that the largest star is the Sun. And in the vast cosmic space, there are many stars as big as the sun, this is not clear. If human beings reach a state where they can freely switch between stars and absorb the energy of the stars, they will reach the state of second-level civilization. ”

"Level 3 civilization, that is, galaxy civilization. It has the ability to roam freely through the universe, and its vitality is extremely strong and very long-lasting. Fourth-level civilization, that is, the civilization of the galaxy. Ability to wander between different galaxies, such as between the Nymphs and the Milky Way. And this movement is most likely to occur through wormholes. The fifth-level civilization is the multi-dimensional space transformation civilization. Ability to convert between planets, galaxies, or larger celestial bodies. In fact, it is the movement of the earth that produces electromagnetic waves, and each energy has its own density space. Sixth-level civilization, that is, parallel universe civilization. Able to adapt to two different parallel worlds, and switch freely. Seventh-level civilization, that is, god-level civilization. The existence of the eleventh-level dimension can be said to be the creation of everything else in this civilization, the existence of the ultimate peak of the universe, and the master of creation!"

After listening to Professor Li's story, Wu Lang didn't know what he thought, and his expression kept changing: one moment surprised, one moment frightened, and one moment smiling......

"Young man, what's wrong with you?" Professor Li said, grabbing Wu Lang's pulse.

"Huh"......

Professor Li then let out a soft exclamation, frowned slightly, and carefully gave Wu Lang a pulse, and after a long time, Professor Li looked at Wu Lang with a serious expression.

"Have you ever practiced something like the Ancient Mind Method, how can your pulse beat so slowly, no more than thirty times a minute. Professor Li looked at Wu Lang in amazement.

"I once got the ancient method of "five times and seven waits" by chance, and I practiced it for about five days. Wu Lang hurriedly said.

"It's amazing that you've been able to cultivate to the third time in five days, it's amazing! It seems that you and I are really very fated! Hahaha......" Professor Li was overjoyed and laughed incessantly.

After Wu Lang heard his words, he was stunned and looked at Professor Li inexplicably.

"The so-called five seasons and seven signs are the health preservation ideas of the six seasons and eight signs mentioned by the pre-Qin Taoists, which refers to the gradual stages of kung fu and the physical and mental effects of each stage when practicing qigong. The five times refer to the five stages of the mind from movement to stillness in the initial stage of cultivation. The Seven Candidates refer to the seven stages of the primary stage of cultivation from weak to strong, and the most detailed ones are recorded in the "Storing Spirits and Refining Qi Inscriptions". Among them, the sixth and eighth candidates, the technique is in the formula, not written in the text, passed on by word of mouth, this method is very subtle, so the first five hours and seven waiting books can only be used for hidden words in the text, fearing that the heavens will be leaked. In addition, you can also comprehend it by yourself in the columns, but if you are not a genius of the heavens, you will only know the literal meaning and cannot comprehend the true meaning of its inner meaning. Professor Li looked at Wu Lang with a smile and said.

Then Professor Li must have known the sixth and eighth signs of the six and eight signs, otherwise he would not have said that. Wu Lang said secretly in his heart.

"I understand what you are thinking, and after you truly comprehend the five hours and seven seasons, I will tell you about the sixth and eighth seasons, but that is only my own experience with reference to the experience of the ancients, and you still need to understand it yourself, do you understand what I mean?" Professor Li nodded frequently and said with a smile.

"Thank you, I understand, Professor Lee. Wu Lang hurriedly stood up and bowed to Professor Li.

"No need to do this, we are destined to do it first, it's not early, you go back first, and come to me tomorrow." Professor Li looked at Wu Lang with a look of love and appreciation on his face.

Wu Lang turned his head to look out the window, it was already pitch black, and hurriedly got up to say goodbye to Professor Li.

Sitting in the car, Wu Lang took out his mobile phone that was turned to silent mode, and there were more than 30 missed calls on it, all of which were from Yin Yuting, and then called back and told her that he would be back soon.

The black warrior drove on the silent road, Wu Lang smoked a cigarette, blowing the cool sea breeze, and carefully recalled every word, every sentence, every move, and every smile that Professor Li said today......
