"Before I left here, I thought all the world was like this." Dongmen Youfu said with a smile: "I didn't expect that the outside world is an infinitely open world.

"On the outer planets, people live on the surface of the planets, but the inner world is like a hollow ball, we all live inside the big ball, with our heads facing the center of the circle and our feet facing outward, which is really amazing.

"To be honest, when I first went out three years ago, I was also shocked for several days, and everything outside felt extremely fresh."

Qin Guan: "It's about the same as my current mood?" ”

Dongmen Youfu: "Almost." ”

Qin Guan smiled, looked up and down, left and right, and suddenly thought that the modeling of the Caolu world was really too perfunctory, and it didn't reflect the whole picture and essence of the inner world at all.

The Moon Shadow City in the Caolu World is really only one city, about two or three miles outside the city, and further out, there is the air wall.

The sky overhead is plain blue, like a semicircular lid.

And the real inner world, there is a forest above the head! And meadows!

At this time, he really wanted to complain about the modeling of the Caolu World Moon Cinema with Dongmen Youfu, but because Grandmaster Liu and others were beside him, he didn't dare to speak casually, so he had to swallow the words he wanted to complain about, and only looked at everything in front of him in a daze.

Dongmen Youfu put his arm on Qin Guan's shoulder and said with a smile: "Actually, there is no difference between the top and bottom of the world, you stand on the other side of the forest and look up, and there is a town above your head; If you stand in the farmland on the left and look up, there are medicine fields and flower beds above your head, all the same. ”

"You have lived in such a small world since you were a child, don't you feel depressed?" Qin Guan asked casually.

"I never thought it before, because I was born here, I got used to it when I was young. Now that I've been out for a long time, I feel different when I come back. ”

……

At the entrance of the world, there is a middle-aged man in a blue plain robe, sitting on a rattan chair, holding a small pot in his hand, drinking tea leisurely, and on his shoulder, a group of orange cats is napping.

Seeing Liu Tufeng and a few people coming in, the man hurriedly stood up: "Senior Liu, you're back." ”

Qin was puzzled, this man looked more than ten years older than Liu Tufeng, and he actually called Liu Tufeng a senior?

But he quickly figured out that Liu Tufeng's realm level was higher than this man's, and his actual age was also older than this man.

Liu Tufeng smiled: "Ah Long, how are you doing lately?" ”

"It's all right, Senior Liu, are you injured?"

"It's okay, don't worry, don't tell anyone."

The middle-aged man in the blue robe nodded: "I understand, the stability of people's hearts is the most important, senior, don't worry, I won't talk nonsense." ”

Liu Tufeng took out a tablet with a packaging box from the storage space and handed it over: "A small gift for you, this is a technology product from the outside world three years ago, I asked for a few, there are a lot of small games in it, learn to play, and one person can pass the time." ”

The man happily took it: "Thank you, senior Liu." ”

Liu Tufeng turned his head again and said to Qin Guan: "By the way, let me introduce you, this is Wang Dalong, who is responsible for guarding the entrance and exit between the two worlds.

"Ah Long, this is Qin Guan, he will be our honored guest in the future, he can come and go freely at any time, you don't have to stop it.

"Qin Guan Xiaoyou may join us in the future, but in the end, it depends on Xiaoyou's own wishes."

Wang Dalong put down the computer packaging box, hugged his fist at Qin Guan and said, "Hello Qin Guan Xiaoyou, it's a pleasure to meet you." ”

Qin Guan also hugged his fist awkwardly: "Ah, fortunately, I will be lucky." ”

Wang Dalong turned his head and asked Liu Tufeng softly: "Senior, why can't I see the realm of Qinguan Xiaoyou?" ”

Liu Tufeng smiled: "We can't see his realm, he claims to be the fourth level now, but he can shuttle through space and come and go at will." ”

Wang Dalong immediately glanced at Qin Guangao and exclaimed, "Could it be that this is the legendary Tianzhong Wizard?" No wonder Senior Liu wants to respect you as a distinguished guest! ”

Qin Guan scratched his head and said modestly: "I have won the award......

To be honest, I can't stand this kind of polite conversation.

How embarrassing it is to be!

Fortunately, Liu Tufeng said: "We still have something to do, so we won't delay." ”

Wang Dalong: "Okay, senior, you are busy. ”

He turned and sat down, eagerly unpacking his tablet and studying it.

Boot......

"The technology of the outside world is really new and interesting!"

……

Qin Guan followed Liu Tufeng and walked forward, and continued to ask curiously: "In this world, there is land up and down, left and right, and there are no stars, where does the light come from?" ”

Liu Tufeng explained simply: "It is the light of the outside world that penetrates and illuminates the world. ”

"The light from the outside is coming in? Through that whirlpool passage behind you? ”

"It can be understood that way."

Qin Guan felt even more incredible.

Dongmen Youfu hurriedly said: "Let me explain this matter!" I've been in the science department for a while, and according to the orthodox scientific theories outside, let me explain this to you! ”

Qin Guan: "Can it be explained by science?" ”

"Of course!" Dongmen Youfu said: "First of all, the world we live in is a three-dimensional world in a high-dimensional world, and you must be able to understand this.

"Then the cosmic space we live in is likely to be made up of a membrane curling in a higher dimensional space."

"Membrane Universe?" Qin Guan thought for a moment and nodded, remembering that he had read such a theory before.

Dongmen Youfu: "From the perspective of the high-dimensional world, our space world is curly, imagine it, just like the small intestine of a person, folded into layers and layers, circle by circle, there are countless folds on the intestinal wall.

"According to scientific theory, between these folded folded membranes, a space world is formed.

"There are some substances that can move between spaces through folded membranes, and some substances that cannot.

"According to those scientists, gravity can travel between dimensions; Light, as well as various particles and energy, can penetrate the film of space. ”

Qin Guan nodded: "Mm-hmm, so the light emitted by the stars in the outside world can shine through." ”

"Yes. Therefore, we have the alternation of morning and dusk here, and there is time, which is synchronized with the outside world. Dongmen Youfu continued: "These things, you must understand them from the height of dimensional space, not intuitively from visual space."

"If you want to understand the concept of the dimensional world, you must forget the perception of visual space, because the human eye can only see the three-dimensional world, but the mind can perceive a higher level of existence!"

Qin Guan: "Well, I almost understand, for example, there is a two-dimensional world on a piece of paper, and the light from the three-dimensional world can naturally illuminate the whole paper, but the creatures of the two-dimensional world on the paper can't see the light source. ”

Dongmen Youfu: "Yes! That's pretty much what it means. Qin Guan, you are very smart, I listened to those scientists several times at that time, and I almost understood it~~"

Qin said that our nine-year compulsory education is not for nothing......

Liu Tufeng was confused when he heard it, and said in confusion: "Ah Fu, what you said is really too abstract, when did you learn this knowledge?" ”
