"You said we should find an object with only one side?"

The nine great sages looked at each other.

"How is this possible?" An old man with a quick temper shook his head flatly.

Yu Ling added "cruelly": "It won't work if you draw it, you have to have something real."

The old man looked suspicious and said, "Are you sure you really know the answer?"

Mo Ling said softly: "Cezia, don't question the guest casually. I had never thought about this kind of question before he asked, but now that I think about it carefully, maybe there really is such a wonderful structure."

Yu Ling couldn't help but feel a sudden thought. It had only been a few seconds. Could it be that the great sage Mo Ling had figured it out? In order to increase the difficulty, he didn't even dare to mention paper tapes and curved surfaces. He was afraid that a few people would wait a minute.

Think of ways to make two dimensions three-dimensional.

Although on earth, teenage middle school students all know the structure of the Möbius strip, if the German mathematician had not first proposed it, then college students, let alone middle school students, might not be able to figure out this kind of structure with only one

The magic magical structure of one-sided curved surface.

After all, knowing and creating are two different things.

Fortunately, Mo Ling hadn't figured it out yet, so he just discussed it quietly with the other great sages. Nian Yubai even pulled Yu Ling's sleeve and whispered: "Aling, you really aren't talking nonsense, are you?"

"No."

"Are you serious? How can such a ghost exist? It's simply anti-human."

"If you knew, you would be the great sage of the Yago tribe."

"Then how did you know?" Nian Yubai was puzzled.

"I just use other people's ideas and creations."

While the two were talking, the great sages of the Yago clan across from them had already begun to operate, and a heated argument broke out during the process. Yu Ling couldn't help but feel a little shuddered when she saw that they had studied from various cubes to flat surfaces.

Did he underestimate these great sages? I thought they were just pure philosophers, but I didn’t expect that this pace was heading towards omnipotence?

"I think it is absolutely impossible for that kind of structure to exist on a flat surface!" A great sage said flatly.

"There is still some hope of converting two faces into one, wouldn't those multi-faceted cubes be even more impossible?" someone retorted.

"But in a multi-faceted cube, there are still angle changes between each face, but in a planar structure, the yin side and the yang side are completely opposite, and it is impossible for the two to be integrated!"

"Speaking of angles...is it an angle problem? If the plane is curved..." Mo Ling said thoughtfully.

Nian Yubai had a bad premonition inexplicably, and jumped out quickly: "That, that, five minutes are up!"

"So fast?" Several great sages looked surprised.

One person looked at the timetable hanging high on the wall of the tower, and said with some regret and frustration: "It has indeed arrived, and it is several seconds over."

An old man scratched his hair and said: "You have overcome this problem, but I have to figure it out. It's just a little bit away. You guys wait nearby for a while!"

Nian Yubai could only be speechless. These people were completely obsessed with research and couldn't extricate themselves. They were scared.

After a few more minutes, Mo Ling suddenly raised his head and looked at Yu Ling and said: "We thought about it, the structure you mentioned can only be realized on a curved surface. Is it possible to twist a plane by 180 degrees?

Realize the connection between the Yin side and the Yang side?”

At this moment, Yu Ling suddenly felt a little lucky. Fortunately, Mo Ling "made it his own fault" and gave himself a five-minute time limit. Fortunately, these people were willing to admit defeat.

Yu Ling nodded, casually wrapped a piece of paper tape around the Möbius strip, and said softly: "That's true."

"It's a very interesting structure. If a formation is built based on this, it will probably be an endless and brilliant illusion formation that can only be forcibly broken through violent means." Mo Ling sighed with emotion.

When the formation was mentioned, Yu Bai became more energetic: "Great Sage, do you also know the formation?"

Mo Ling smiled slightly and said: "To be precise, the original formation was studied by us and human cultivators. My human friend proposed the node theory. From then on, the construction of the formation became orderly and followable.

The magnitude reduces the presence of chance.”

Nian Yu Baideng immediately felt confused as if he had seen a historical figure.

"If you are interested in formations, why not analyze this magical surface structure into formations? It should be a major breakthrough in the field of magic formations." Mo Ling thought.

"Well, I'll try my best..." Nian Yubai picked up the paper tape and looked at it, but he could only say weakly without any confidence.

"Next question?" an old man asked impatiently, looking a little excited.

They had been bored for too long and finally met an interesting young man. Of course, they were full of expectations and wanted to dig out more interesting things from him.

However, Yu Ling already had a sense of crisis that could not be deceived, so she could only bite the bullet and continue: "A mink fell into a five-meter-deep hole, and it fell to the bottom in one second, so what color is this mink?

"

Although this question was originally supposed to be about polar bears, the last time he looked at geography, he found that there were no bears like bears in the north and south poles of the planet, so he had to use ice silver sables to fill in the question. Fortunately, the gravity of the two worlds is different.

Not big, some principles are similar, otherwise many problems will not apply.

This question is actually very simple. It is just a bit confusing at first glance, but the knowledge involved is not difficult. But in this world, let the few great sages in front of me figure out gravity in five minutes.

The formula is really a bit difficult.

This time, several great sages started the discussion mode without any delay. Several people were arguing and almost started fighting. Nian Yubai quickly pulled Dong Su away from the war zone.

"Aling, I'm not telling you, why do you have so many weird questions?" Nian Yubai whispered.

Yu Ling said calmly: "If I don't deliberately embarrass others, we will be embarrassed by Enrika."

Nian Yubai said with a weird look on his face: "Sometimes I really want to dig open your head to see what's inside."

He was silent for a moment and suddenly asked: "That time, when I first entered the dark abyss, the you I saw on that cliff... was it really you?"

Nian Yubai seemed to have spent a lot of effort to squeeze out the question, but Yu Ling said without surprise: "You are really patient if you can bear to ask until now."

Nian Yubai smiled bitterly and said nothing. During that period of crisis, it was not the time to get to the bottom of it. In fact, he had never dared to ask for fear of getting an incredible result.

But now he suddenly figured out that it was one thing whether Yu Ling was willing to tell some things, but if he didn't ask, it would always be an unsolvable knot. After all, brothers can have secrets, but they can't.

There should be such a thorn.

"I can only say that the me you know is always me, but before that, I was not Yuling."

Nian Yubai said blankly: "What do you mean?"

"Do you want to hear the truth or lies?"

"Nonsense, of course it's the truth!"

"Two years ago, I came to this world from another world. I still don't understand why."

"...Aling, even if you are talking nonsense, can you make a draft first before talking about it? This is the first time I have seen someone who is talking nonsense and talking so seriously that I almost believe it to be true." Nian Yubai twitched the corner of his mouth, as if he couldn't help but want to laugh.

.

Yu Ling said no more.

Nian Yubai's smile suddenly froze, and he said with some difficulty: "Is it really true?"

"..."

Nian Yubai was silent for a moment before saying, "I won't tell others."

"It's not that I deliberately concealed it. In fact, it's not an ulterior secret. But not only is there no point in telling this kind of thing, but it will be regarded as crazy. Even you are still doubtful about it now."

Nian Yubai did not shake his head or nod. He just exhaled a long breath in silence and smiled slightly: "Forget it, you are right, that is meaningless. As long as I know you, you will always be you, and the rest will be the same."
