"Huh? Short on time? Because the brain received too much information in a short period of time, Kiriko didn't react for a while, but the next moment she understood the meaning of what Xue Feng said, "Could it be that here...... After holding on for so long, I finally can't hold on anymore!? ”

“…… I don't remember which of the two of us would have the title and potential of the Emperor of Tragedy, right? After a moment of silence, Xue Feng complained expressionlessly. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Well, it looks like Kiriko hasn't reacted until now. Anyway, when Kiriko asked questions before, from the action to the expression, she was already a complete girl, and if she changed back to a boy now, it would probably be more troublesome, for example, being called weak by others, a pseudo-mother or something.

"Ahaha......" Kiriko, who seemed to react to what she had said, touched her long black hair and laughed embarrassedly.

"It's coming to an end soon, but it's not because it's almost time to die." Xue Feng didn't say anything, but directly began to popularize science for Kiriko. (Science popularization is abbreviated as popular science, what is the abbreviation of mystery popularization?) Shenpu? I feel that this abbreviation is actually the popularization of theology. Sure enough, should it be the abbreviation of Mipu? ）

"To be more accurate and simple, the existence of this space, or the countdown, begins when we open the door." Yukikaze first answered Kiriko's question before giving the relevant explanation.

"Kiriko, now as a god, you should be more aware than before, the difficulty of fixing a stable space between the front and back of the world." Yukikaze asked.

"Hmm." For this, Kiriko nodded without the slightest hesitation. Even now that she has become a god, even if she can use all the magic and divine powers, Kiriko is not sure that she can fix a piece of space in the cracks. If it's only temporary, it's okay, and the permanent type is estimated that Tongzi may not be able to do it in this life.

Although there are also reasons for the innate limitations of the gods (the abilities that the gods are proficient in vary depending on the priesthood), it is enough to explain the difficulty of this matter.

"Unless this technique is obtained by adventure, or because of racial talent, it is almost impossible for mortal civilization to fully master it." Xue Feng continued, "Even if it seems to have mastered it, it is only a little bit of a superficial mastery, and it is only a trick to achieve this. ”

"That's right, the construction of this space was done by tricks." Without waiting for Kiriko to comprehend what she meant, Yukikaze directly announced, "This tower in the center of the city was built precisely so that this room can be located between the front and back. ”

"But even then, the entire civilization can only build such a single building." Xue Feng calmly told the truth, "Because what they use is the difference coordinate construction method." ”

Differential Coordinate Construction? Kiriko was confused.

"As the name suggests, this construction method refers to the same building built in different dimensions, with specially arranged differences in coordinates." Knowing that Kiriko didn't have any concept of this term, Yukikaze explained directly.

"First of all, Kiriko, you should also see it, but what I want to explain here is that this civilization is a civilization that is more inclined to the mysterious side. Compared with the technology side, the mysterious side is in architecture, and there will be a variety of magical buildings and corresponding construction methods in the early stage. ”

"The construction of two buildings with the same equalization in different dimensions to achieve various functions is a very common construction method on the mysterious side, and we generally call it the allergic construction method. Generally, it can already involve the mysterious side civilization of another dimension, and this kind of popular construction method will be used, and the representative buildings of this construction method are: twin towers, positive and negative fortresses, and so on. ”

Then, the upgraded version of the isostatic construction method is the multi-dimensional construction method, that is, the construction method of building different spaces of the same building in different dimensions, so that the whole building has the same or even more functions as the isometric construction method. This is a kind of construction method that can only be used by mysterious side civilizations that have a considerable understanding of space and dimensions, and the representative buildings of this construction method are: multiple fortresses, endless fortresses, etc. (generally all rooms belong to buildings in different spaces, all belong to this construction method). ”

"Finally, an upgraded version of the multidimensional construction method is the construction method used in the tower where we are today: the differential coordinate construction method. This is a construction method that is impossible for a single person (not a supernova genius) to do, and the precise calculation of coordinates that need to be fine-tuned must already rely on the efforts of a civilization. As for the other requirements, they are also quite harsh, so even if a very small number of mortal civilizations have mastered this construction method, they will not necessarily be able to build this kind of building in the glory days. As a result, such structures are generally in the hands of at least otherworldly civilizations. ”

"If you explain it briefly, you may be a little troublesome for Kiriko, so I'll give a field explanation directly based on this tower."

After thinking for a moment, Yukikaze seemed to say this for Kiriko's basic knowledge and comprehension, but even though Kiriko knew about it clearly, she still had an urge to be sad.

"Kiriko, did you feel the transformation of space when you walked up?"

“…… It feels like it's something or nothing, it's not obvious, and it's not certain. After recalling it carefully, Kiriko replied.

"You're not wrong, the space changes every time we go up a floor." Xue Feng nodded and said, "You don't have to worry about the transformation of space that can't be clearly perceived. The almost imperceptible spatial transformation is the distinguishing feature of multi-dimensional architecture after maturity. If you're not a god or a law class, you probably won't be aware of it at all. ”

"However, that's not what we're going to talk about now, so I'll just go through it. Kiriko, since you can perceive the spatial shift, I don't need to explain anything. ”

"However, compared to other multi-dimensional buildings, this tower does not divide the space within the building into different spaces, because it involves only three spaces from beginning to end."

"They are, between the cracks we are in now, the front of the world, and the opposite side of the world."

Hearing this, Kiriko's mind flashed with inspiration, as if she had found some answer, but Kiriko was not able to catch this flash, but some uncertain vague predictions began to emerge from her heart.

With his knowledge of the magic he had deciphered this civilization, in the center of the room was a table (table?) with various textures all over the room. Yukikaze, who was operating on it, did not notice Kiriko's flashing aura and the subsequent painstaking meditation, but continued to explain himself.

When did Yukikaze crack that knowledge, you ask? Well, you have to know that in order to stabilize the space between different dimensions, each layer of space transformation must use a magic array. Although they covered it up, the other party did not completely hide these magic arrays, and the various lines and paintings on the walls of the stairs were all corners of the magic array. And with Xue Feng's knowledge and talent for the mysterious side, after climbing one or two hundred floors, he will naturally be able to crack the magic knowledge of a civilization.

You must know that as a mystical civilization, from the very beginning, it has been studied, developed and popularized from the most mysterious place on the surface of the world, that is, the law. Therefore, as long as you can master a certain amount of knowledge of the law, it is very easy to crack the knowledge of the mysterious side (unless the other party is on the wrong path...... ）。 And because of the similarity of the world, a lot of magical knowledge is almost identical except for a different name. Therefore, just like the earth on the technology side to crack the alien spaceship on the same technology side, although the speed is not fast (referring to the fact that there are no geniuses above the geek level to join the crack), it will definitely not be helpless.

As for the text or something...... You must know that for an archmage, words and words are never an obstacle!

That's the end of this digression, so let's turn our attention to Yukikaze's explanation.

As explained earlier, the differential coordinate construction method refers to the deliberate calculation and fine-tuning of the coordinates of the building space located in different dimensions for a certain goal. It should be noted that the coordinates mentioned here are not the spatial coordinates in the conventional concept, but the dimensional coordinates, or the spatial concept coordinates. If you had to give a simple example...... Kiriko, do you know the shadow plane that completely covers the plane of reality, almost exactly equal to the plane of reality? ”

Without waiting for Kiriko to answer anything, Yukikaze continued to explain.

"In the case of the twin towers, in the absence of other accidents, the coordinates of the two towers of the twin towers are always equal, or even identical. However, in the case of differential coordinate construction, there will be subtle differences in the coordinates of the two towers without affecting the links and other functions at all, such as moving one meter to the north. ”

"The difference in the coordinates of this tower is that with each floor you go up, the space you are in will be a little closer to the gap."

Yukikaze casually told the tower's ultimate secret. By the way, this is also the key reason why the aura of "sin" will continue to diminish as the floor rises, in addition to the constant change of space on the front and back of the world, approaching the gap also makes it difficult to infect the aura of "sin".

"I see." Kiriko seemed to finally remember the flash of her own burst, and nodded abruptly. However, then Kiriko asked suspiciously, "Huh? Isn't that supposed to be a pretty solid space? Why is there not much time left to exist? ”

If you understand it according to common sense, Kiriko's doubts are very normal, just like a high-rise building needs a thick enough foundation, this tall tower has built one or two hundred floors in order to allow the top floor room to enter the cracks!

"Don't bring the common sense of the technology side into the mystery side!" Xue Feng covered his face with his hands and said, "In the mysterious side, many low-level technology side common sense is wrong!" ”

Feeling the feeling of doubt coming from behind, Xue Feng helplessly explained: "Maybe for ordinary buildings and most special buildings, the thicker the foundation, the more stable the whole. But between the front and back of the world, there is no ordinary space or dimension, and the common sense you have is almost completely invalid there. ”

"And as I've said before, the tower's approach to the technology of holding the space between the front and back is nothing more than a trick. As a price to pay, this space naturally can't be so stable! ”

"In order to be able to stabilize between the cracks for a long time, this room is sealed with a seal that is almost as if it were standing still in time, so that the space can do this. And our previous act of opening the gate is equivalent to breaking this seal. ”

"So, although the entire space can not last long in the cracks, our entry has pushed this space directly into the countdown to destruction!"

"So, what we did...... This space ......" After hearing Yukikaze's explanation, the kind-hearted Kiriko suddenly panicked.

"Don't worry, even if we don't come, it won't be long before this space will still be destroyed, don't forget that at this moment, the aura of 'sin' is still infecting this tower." Yukiko comforted Kiriko and said, "And, Kiriko, why do you think this room is sealed between the front and back of the world?" ”

"Why?" Accompanied by Xuefeng's question, Kiriko, whose mind has been following Xuefeng's explanation, calmed down and thought about it this time, "In this dangerous place, it costs a lot of money, just to stabilize one"
