Chapter 3153: Boundless Bottle
The black-haired witch said as she hurriedly pulled Shade's sleeve and continued to walk inside. After passing through a dizzying array of goods, they found a trap door embedded in the ground at the corner at the end of the store:
"A little bit of knowledge. Because Willendel City served as a battle fortress during the Carsenrick Unification War, almost every house in most of the city, including the current Upper Town, has a basement. Some houses have a basement area that is larger than the ground area."
She motioned for Shade to enter the basement, which was much more plain than the luxurious decoration on the ground floor. It looked like a store's warehouse, but there were also several tailoring tables and sewing machines placed near the entrance.
Xia De was about to comment on this place, then turned around and found that Sylvia was standing on the ground and did not come down.
"That's the problem. Recently, the girls found that after the trapdoor was closed, it could not be opened from underground, but it could be opened normally from the ground. This situation only occurs when there is only one person underground and stays alone for more than ten minutes. I also checked it, but found no problem, so I want you to help take a look."
Sylvia stood above and explained, and Shade nodded to show that he understood:
"Well, close the door. If I don't come out in twenty minutes, you can help open the door from the top."
The witch smiled and made a gesture that it was all right, then she really closed the door leading to the basement, and then Shade heard the sound of the lock being locked.
"Ok?"
Xia De blinked and shouted upwards:
"Sylvia, did you lock it?"
"Of course not, and it's not a problem for you to be locked, is it?"
The girl on the ground laughed, so Shade stopped asking questions.
At this moment, he felt around and found that there was indeed no trace of any element. He touched the wall again, and then checked the ceiling and floor of the basement, and there was no problem either.
"Strong spatial perception."
Everything around him was ordinary, so Xia De had no choice but to wait for ten minutes to pass. Although he didn't like to rummage through other people's things, he still used the remaining time to wander around the basement.
Not only fabrics and cloths, the warehouse also has some art paintings and decorations that are probably spare.
Shade even saw a strange pencil sketch at the back of the warehouse.
There is a hole at the bottom of a bottle, and the neck of the bottle extends and then twists into the inside of the bottle and finally connects with the hole at the bottom of the bottle.
This is not a real object. The "bottle" has no "edges" and the surface does not end. A fly can fly directly from the inside to the outside of the bottle without passing through the surface. In other words, there is no distinction between inside and outside.
Perhaps to most people in this world, this is just an artistic and eccentric painting, but outsiders recognize it for what it is:
“Klein bottle.”
This is the name given to this kind of existence by the strangers’ hometown. Simply put, this is an object in four-dimensional space, and its structure and properties cannot be fully realized in three-dimensional space, so it cannot be truly created in the material world.
A piece of paper strip twisted and connected to each other can create a "Mobius strip", where there is no front and back. But this three-dimensional twisting in front of us cannot be reproduced in reality, and can only be simply summarized as the bottle has no inside and outside.
This painting was created by Sylvia, because the witch's cursive signature is on the lower right corner of the sketch. Shade felt that Sylvia had deliberately put it here for him to see. The witch was just about to make the painting glow to remind Shade that this was an important item.
However, this painting was also an ordinary item, of which Shade was very sure.
After ten minutes, nothing strange happened in the basement. Xia De walked up the stairs and took the initiative to open the basement door. After finding that it was locked, he knocked on it:
"The key to the door."
With a click, the outer lock fell off automatically. Now that he had been promoted to a higher level, he could even use this magic just by touching the door, without having to touch the lock directly.
Curious about what happened here, Xia De opened the door upwards, and then saw that outside was not the "Gorgeous Cloth Workshop", but a dirt passage sloping upwards.
"This is powerful spatial perception."
After using the magic, he frowned suddenly. The magic was successful, but he could not understand the meaning of the spatial structure he saw. What he detected was not a complex maze or a long passage with unknown boundaries. He saw it but could not understand it:
"It turns out that spatial perception abilities have this kind of nemesis."
After a little exploration, Shade entered the dirt passage in front of him. After a short journey, the faint light of the silver moon illuminated a red brick wall at the end of the curved passage. After Shade used fossils to turn mud to open the brick wall, he saw the back of a huge painting board.
After pushing the drawing board and leaving the passage, they returned to the basement of the store. The painting standing on the wall was, of course, Sylvia's handmade sketch.
The clues were so obvious that Xia De didn't even need to leave marks repeatedly to test them before he understood the principle of "space cycle".
The general spatial cycle is to distort the position of space to achieve a "end-to-end connection" like a ring. Although what we encountered this time looks the same, it should actually be the "Klein bottle" left by Sylvia.
Of course, its name in this world, Xia De, is not clear.
"So how do we crack it?"
Because it is impossible to understand the spatial structure of the outside world, "Raglai's Jump" cannot jump out of here; and since this is not a lock, but just a special spatial phenomenon, the "Key to the Door" naturally does not work.
"Space Stabilization Aura!"
I put my right foot on the ground, but nothing happened around me.
Xia De continued to think. In fact, he didn’t know much about the so-called "Klein bottle". He had only read some theoretical knowledge.
The "Klein bottle" involves the concept of "borderlessness". If this is really a space constructed according to this concept, then in the superficial understanding of outsiders, the key to breaking this space lies in understanding the fluidity, continuity and interaction of dimensions of space.
In theory, this requires building a countermeasure through several key mathematical and topological concepts. But in fact, the simplest way to do it is:
“Cut the boundless space, flip it, twist it, and then piece it back together” or “Although the space as a whole has a complex structure, it still looks like a normal space when viewed locally, so the boundless flowing space can be transformed into a space with boundaries and orientation by folding the space and performing local mapping transformation.”
Of course, although Shade knew the theory, he couldn't perform such a complicated operation.
The sound of the flute sounded, and the red butterflies emerged from the void. The butterflies flew around Shade for a circle before landing on the ground and transforming into two sisters holding hands:
"Sir, you really thought of us. A little tip - the witch said in advance that you can only ask us for help once tonight!"
Grace said with a smile, not at all surprised to be summoned, and the power of the chosen one of space could obviously penetrate the special space where Shad was now at will.
Helen, who was wearing a black dress, held Shade's hand and asked with a smile:
"Sir, do you need us to help you escape from here?"
Xia De shook his head, but he already knew that this incident was indeed Sylvia's own work and not a "trouble":
"No need to take me out directly. Can you cut the space, twist it and reshape it?"
He pointed to the sketch behind him and explained the current space environment in detail to the two sisters. Grace and Helen listened with a smile, then nodded quickly and said together:
"You pass!"
Grace took out a box from somewhere and handed it to Shade, then pointed in the direction of the basement door:
"The space has been restored, sir, you can leave now, have fun tonight!"
Then they turned into a group of butterflies again and circled around Shade before disappearing. Shade opened the box in his hand and found a piece of silk cloth inside. On the silk cloth was written a complex and unique ritual in black ink:
[Spatial Ritual·Unbounded Bottle: Construct a unique looping space. If you don’t understand the structure of the looping space, you can’t leave the loop by the usual method of breaking the looping space.]
The silk cloth was densely packed with all the details of the ritual, as well as the design ideas and thoughts. It looked like Sylvia had created the ritual herself. If she were given more time, she might be able to turn the ritual into her own magic, and eventually construct a unique space maze lock:
"It's really amazing."
The piece of silk cloth in Xia De's hand could be considered the product of Sylvia's hard work. This kind of precious knowledge could only be passed on to apprentices after being tested, but Sylvia gave it to Xia De so easily:
“Is this considered a reward for completing a level?”
After he put away the silk cloth, he successfully returned to the ground part of "Gorgeous Cloth Workshop" from the basement entrance.
Although the lights in the store were still on, Sylvia was no longer there. However, some of the goods had been cleared out. In the back half of the store, which sold intimate fabrics, stood a dressing doll wearing a gorgeous lady's dress.
As soon as Xia De showed up, the black ball in the puppet's hand hit Xia De. Xia De instinctively raised his hand to block it, and then felt that he had blocked a ball, and the force was not strong.
After the ball touched his palm, it immediately bounced back to the wax figure. After a shield with complex golden spiral lines flashed in front of the wax figure, the "ball" was bounced back to Shade again. This time he still chose to block it with his hand, and then he clearly felt that the power of the ball had increased a lot.
The "ball" bounced back towards the wax figure again, and after it hit the golden spiral shield that flashed in front of the wax figure for the second time, the force of the "ball" that bounced for the third time was so great that even Xia De felt a little pain.
