"The dimensions of the universe as we know them are extremely limited. Hewen said.

Kelly nodded:

"Hmm. ”

Hervin spread out a huge map on the table.

This is not a concrete geographical map, but an abstract concept map, and the content that the map wants to express cannot be depicted with lines and color blocks.

The professor asked:

"Again, what do you call that ability. ”

Kelly looked a little nervous, perhaps because it was the first time she had talked to someone about her most important secret:

"Behind-the-scenes vision, this ability is innate, I was able to recognize Professor Herwin in disguise before, because I had used this vision to see your disguised image, and your behind-the-scenes image has appeared many times in my eyes of different types. ”

Hewen nodded:

"Behind the scenes is a really accurate word, maybe some kind of supernatural intuition made you name your abilities by this word, but you said you saw other images of me?"

Kelly nodded and explained:

"That's right, the first time I met you, you were a man with six spider arms, a hollow in his chest, and a skin overflowing with madness and monsters.

"Honestly, your anatomy has a beauty that I can't describe exactly, but on the whole, the monster-like evil madness still has the upper hand, and at first I just thought you had suffered some kind of heartache, and there was a repressive madness under the polite surface. ”

Hewen nodded:

"Are there multiple images? Is this common in your field of vision?"

Kelly shook her head:

"To be sure, there are only two people who have multiple images, one is to teach you, and the other is a beautiful woman with a strange and free personality. ”

Kelly hesitated, but still did not say that Hola had also changed, that it was not strictly a multiple image, but an unfixed image.

As far as Hewen knows, all creatures have a fixed image when they go behind the scenes, and this image depends on many reasons, and the behind-the-scenes images of different life forms can be made up of different factors.

As long as a small number of biological individuals will appear differently behind the scenes, a small number of people with multiple personality disorder and polychic disorder may have this condition.

As for the reason why he has two images?

There were more than two images of him, and what Kelly saw was the appearance he had decided to adopt when he had gone behind the scenes.

That's right, behind-the-scenes vision is not some kind of spiritual vision that can interpret everything in the world, but can really see another world.

Now Hewen has basically determined that this vision is not a coincidence:

"You also mentioned a curved approach?"

Kelly adds:

"Curve or polyline. ”

Herwin asked:

"What's that like?"

Kelly grimaced, as if it was difficult to explain this strange way of moving in Anglo-Ransian.

"Well, I can probably see some basic laws of physics that I can't usually see, of course, I don't know whether this rule is in line with physics or not, in short, a law that humans have not mastered and known for the time being is spreading out in front of my eyes in a way that can be realized.

"Actually, I don't know how movement works, but I can barely follow the visual route. ”

Herwin pointed his finger on the table:

"In other words, although you think that this is a very advanced cosmic law, you are not unaware of its principle, but you just follow your instinct and use this law?"

Kelly agreed:

"That's about it. ”

Hewen first pointed to the map on the table.

Nine massive spheres are arranged in a mathematical manner.

"Astronomers and modern physicists are curious about the world beyond the atmosphere, trying with all their might to fill in our partial understanding of the universe. ”

Hewen points to the sphere in the middle:

"Midgard, Atrium, or Orlens, the planet beneath our feet.

"But while Midgard means the whole of Orens, it's more about the continent beneath our feet, and neither usage is problematic. ”

Kelly looked at the other planets:

"So is this a planet near us?"

Hewen paused:

"Yes and no, you can't build a flying machine and just fly out of the atmosphere to eight other worlds, they don't revolve around the sun in the material universe, but on the world tree. ”

"The World Tree Yggdrasil is in a dimension very close to our universe, and the nine worlds are pinned on it at the same time, and so is Midgard.

"The human world is a special case among the nine worlds, Midgard exists here and above the World Tree and our universe at the same time, and the World Tree dimension can be said to be a dimension that is placed on the main material universe through Ollens.

However, it is more correct to say that the Nine Great Worlds were originally part of the main material universe, but after a certain ancient war, they broke away from the main universe and existed in a more detached and convenient form. ”

This is why Odin once led the gods and giants to form an alliance against the great enemy above the stars, because the atrium is the most important part of the World Tree, the part that connects with reality.

If the Atrium falls, the Eight Worlds are likely to be out of safety and back within the range of the enemies of the real universe.

Hervin says:

"This is one dimension, and it is the closest dimension to us, and what you see behind the scenes is actually another dimension, which we call the dimension of the world behind the scenes. ”

Kelly asked:

"Behind the scenes. ”

Hewen pointed to another area on the map, parallel to the World Tree system formed by the Nine Worlds, which was filled with a large number of blurry colors and distorted graphics.

"The world behind the scenes, so called because this world is only separated from our universe by a curtain.

"It stands to reason that although this world is very similar to our universe, the living forms in the main universe do not exist behind the scenes at the same time, that is, if you see the real behind-the-scenes universe, there should be no human projections.

"So what you see isn't exactly what you see behind the scenes, it's what the things in front of you would have if they were behind the scenes.

"After all, the image of most people who go behind the scenes will be completely different from the original, and through your description of my image, I can roughly confirm that this is the case. ”

Kelly muttered to herself:

"Another world? The illusion I've been seeing turns out to be this kind of thing, so what is the real behind-the-scenes universe?"

Hewen could detect a strong desire for knowledge and exploration from this sentence.

He took out a long-prepared glove from the drawer and put it on, then gently pinched a corner of reality, tearing open the fragile curtain, and letting the world hidden behind it reveal to the two of them.
