"You say let's find an object that has only one face?"

The nine great sages looked at each other.

"How is this possible?" said an old man with a quick temper who shook his head categorically.

Yuling "ruthless" added: "It is not possible to draw it, there must be a physical object." ”

The old man looked skeptical, "Are you sure you really know the answer?"

Mo Ling said softly: "Sezia, 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 will really be such a wonderful structure." ”

Yu Ling couldn't help but feel a sudden feeling in his heart, it was only a few seconds, could it be that this Mo Ling Great Sage came up with it? In order to increase the difficulty, he didn't even dare to mention the paper tape and the curved surface, for fear that a few people would come up with a three-dimensional two-dimensional method in minutes.

Although on Earth, teenage middle school students know the structure of Möbius belts, if it were not for the German mathematician who first proposed it, let alone middle school students, I am afraid that college students may not have been able to come up with this magical structure with only one side of the curved surface.

After all, knowing and creating are two different things.

Fortunately, Mo Ling hadn't figured out his thoughts yet, but just discussed softly with the other great sages, and Nian Yubai even tugged at Yuling's sleeve and whispered, "Ah Ling, you really don't have any nonsense, right?"

"Nope. ”

"Are you serious? How could such a thing be there, it's anti-human. ”

"If only you knew you were the Great Sage of the Yago Clan. ”

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

"Other people's ideas and creations are just used by me. ”

While the two were talking, the great sages of the Yago tribe on the other side had already begun to operate, and a fierce argument broke out during the period. Yu Ling couldn't help but feel a slight chill in his heart when he saw that they had studied from various cubes all the way to the plane.

Did he underestimate these great sages? I thought they were just pure philosophers, but I didn't expect that this rhythm was going to run towards omnipotence?

"I don't think there's a structure like that on the plane!" said a great sage flatly.

"It's a bit hopeful to turn two faces into one, but aren't those multi-faceted cubes even more impossible?" someone retorted.

"But the multi-faceted cube still has angular changes between each face, and the plane structure is the yin side and the yang side are diametrically opposed, and the two cannot be integrated at all!"

"Speaking of angles...... If the plane is bent...... Mo Ling thought thoughtfully.

Nian Yubai inexplicably had a bad premonition, and hurriedly jumped out and said, "That, that, it's been five minutes!"

"So fast?" several great sages looked surprised.

One person looked at the time engraved watch hanging high on the wall of the tower, and said with some regret and frustration: "It has indeed arrived, and it has exceeded several seconds." ”

An old man scratched his hair and said, "You have passed this question, but I have to think of it, it's just a little bit close, you guys wait by the side for a while!"

Nian Yubai could only be speechless, this group of people was completely addicted to research and couldn't extricate themselves, 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 said must be on a curved surface to be possible, is it possible to twist a plane by one hundred and eighty degrees to realize the docking of the yin and yang sides?"

At this moment, Yuling suddenly felt a little lucky, fortunately that Mo Ling "did his own evil" to give himself a five-minute time limit, and fortunately, these people were willing to gamble and lose.

Yuling nodded, casually wrapped a paper tape around the Möbius belt, and said softly: "That's true." ”

"It's a very interesting structure, if you build a formation based on this, I'm afraid it will be an endless and endless magic array, which can only be forcibly broken by violent means. Mo Ling said with emotion.

When it came to the formation, Nian Yubai came to the spirit: "Great sage, you also know the formation?"

Mo Ling smiled slightly: "To be precise, the origin of the formation was researched together with the Terran cultivators, and my Terran friend proposed the node theory, and since then the formation construction has become orderly and followable, greatly reducing the existence of chance." ”

When Nian Yu Bai Deng, he had a sense of confusion when he saw a historical figure.

"If you are interested in the formation, it is better to analyze this magical surface structure into a formation, which should be a big breakthrough in the phantom formation. Mo Ling thought about it.

"Uh, I'll try to ...... as much as I can," Nian Yubai picked up the tape and looked at it, and could only say weakly without confidence.

"What's next?" asked an old man impatiently, a little excited to see how he looked.

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

However, Yuling already had a sense of crisis that could not move, so he could only stubbornly continue: "A mink fell into a five-meter-deep hole, and it ended up in a second, so what color is this mink?"

Although this question was originally supposed to be about polar bears, the last time he looked at the geography, he found that there were no bears at the north and south poles of the planet, so he had to use the ice silver marten to fill the number. Fortunately, the gravity of the two worlds is not very different, and some principles are similar, otherwise many problems would not apply.

Speaking of this question, it is actually very simple, it is just a little inexplicable at first glance, but the knowledge involved is not difficult, but in this world, it is really a little difficult to let a few great sages in front of him figure out the gravity formula within five minutes.

Several great sages didn't dare to delay for a moment this time and turned on the discussion mode, several people were arguing and arguing, and Nian Yubai hurriedly pulled the end of winter away from the war zone.

"Ah Ling, didn't I say, why did you have a strange problem?" Nian Yubai whispered.

Yu Ling said lightly: "I don't deliberately embarrass people, we are going to be embarrassed by Enrica." ”

Nian Yubai said with a strange expression: "Sometimes I really want to dig out your head to see what is inside." ”

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

Nian Yubai seemed to have struggled to squeeze out this question with great effort, but Yu Ling was not surprised and said, "You can endure until now to ask, but you are really patient." ”

Nian Yubai smiled bitterly, the crisis was turbulent during that time, and it was not time to get to the bottom of it at all, in fact, he had never dared to ask, for fear of getting an unbelievable result.

But now he suddenly figured it out, there are some things that Yu Ling is willing to say is the same thing, but if he doesn't ask, it will always be a knot in his heart that cannot be untied. After all, there can be secrets between brothers, but there shouldn't be such a thorn.

"All I can say is that the me you know has always been me, but before that, I wasn't Yuling. ”

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

"Do you want to hear the truth or a lie?"

"Nonsense, of course it's true!"

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

“...... Ah Ling, even if you are, can you make a draft first, this is the first time I have seen someone who is so serious that I almost believe it is true. Nian Yubai tugged at the corners of his mouth, as if he couldn't help but want to laugh.

Yuling didn't speak again.

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'm deliberately hiding it, in fact, it's not a secret to tell, but this kind of thing is not only meaningless, but it will be regarded as a psychopath, and even you are still half-skeptical now. ”

Nian Yubai didn't shake his head or nod, just exhaled a long breath in silence, and smiled slightly: "Forget it, you're right, it doesn't make sense, as long as the person I know is always you, and the rest doesn't matter." No matter who you are, you are the best brother of my Nian Yubai!"
