The promenade is flanked by stained glass depicting solemn patterns with religious implications, the ornate curtains are rolled up, the gray stone pillars stand on both sides, and the ceiling, also a long scroll, seems to depict the goddess's creation of the world, and the floor of the corridor is a black and white pattern composed of obsidian and marble, which looks like a chessboard.

The corridor was long, shrouded in a faint white fog that grew thicker and thicker in the distance, with no end in sight.

"Looks like this is another kind of space?"

Rosen asked, he didn't know much about the mage's strange things, but he had a vague sense that the corridor seemed to be somewhat different from the previous ones.

"I don't know, I can't feel the traces of magic power, if it's really some weird space, then the mage who arranges this is at least above the level of the silver peak. ”

Karen shook her head, indicating that she didn't know.

"But almost all mages have one thing in common. ”

"What is it?"

Rosen was curious about what all these mages had in common, he didn't have many mages, but each one was full of personality, which really didn't allow him to have an intuitive understanding of this group.

"That's self-confidence to the point of conceit. ”

Karin smiled, not thinking it was a derogatory remark.

"Since the other party has laid this trap, it means that as long as we can break this trap, we will not encounter other spell attacks that are beyond the norm, and the mechanism here should only consider the power here. ”

She pointed to her head, which represented the most revered power of the mages, the power of wisdom.

Indeed, Rosen had encountered a similar trap at the mage observation post in the desert capital of Ishtar, and if he could find a way to break it, it would be very simple, on the contrary, if he had no clue, it would be difficult to break through it with brute force.

"Anyway, let's go ahead and give it a try. ”

Lawson said that there was no other way at the moment, even if they knew that there was a trap ahead, they could only move forward.

However, after walking for a while, Lawson and the others did not encounter any extraordinary events.

There were no other monsters attacking them, and the three were not separated.

The only difference is that when you look back, the door between the quiet has long been submerged in the fog and disappeared.

The front was still shrouded in fog, and their perception could only touch a dozen yards around them, although they didn't encounter any crisis for a while, everyone still maintained a high level of tension and didn't dare to relax in any way.

But all that was left for them was silence.

The thick fog is as if even the sound is absorbed, and the surroundings are silent, and I don't know how long I have walked, but there is still no end in sight.

"Wait, something doesn't seem right. ”

Rosen stopped.

"I found out too. ”

Karen looked at the ceiling and continued.

"This corridor looks like there's no end to it. ”

"What?"

Langton had been gone for so long, although he secretly had some guesses, but after Karen's confirmation, he was also a little surprised.

"The Infinite Corridor Again?"

"Well, if the previous corridor was infinite in horizontal space, now this corridor is infinite in the vertical sense, with no end in sight and no beginning. ”

Karene said thoughtfully, looking at Lawson.

"What do you think?"

"Let's make a mark and keep looking. ”

Rosen said that this is the easiest way, if they are in a loop, then they will always go back to the original place, and conversely, if they don't go back to the same place, then the space is debatable.

As Rosen meant, they made different markings on the walls along the way, but continued to walk for about two quarters of an hour, and there were no markings around the hallway.

"Interesting. ”

Karen did not show panic, but said meaningfully, and it could be seen that her competitive spirit had been aroused by this unknown trapper.

She raised her hand and magically depicted something in mid-air, and at a cursory glance, Lawson looked like some kind of calculus.

After a quarter of an hour, marked by Kalian's long sigh of relief, the movement of her hands finally stopped.

"I already know the secrets here. ”

Rosen remained silent, but waited quietly for Karen's answer.

"It's actually quite simple, we can't get out of here because we haven't made a single change to this corridor. ”

"Change?"

Langton seemed to think of something, but didn't say anything.

"That's right, if this corridor is a piece of music and our goal is to play it to the end, then we haven't even walked a note before, actually. ”

Karen, explaining, also depicts a string of notes in the air, seemingly the melody of an unknown piece of music.

"Wait, you mean, Siegel transform?"

Reacting immediately, Karene nodded as Langton said his conjecture.

"Well, yes, actually, this hallway, the moment we stepped in, was quietly transformed by Siegel. ”

Karen drew a coordinate axis in mid-air where the crosses intersected, with a wavy line on it.

"It's the regular corridor, continuous, and you can go to the end. ”

Then she waved her hand, and the wavy lines turned into vertical segments, lined up in a row, and shortened in turn.

"This is a corridor transformed by Siegel, the continuity in space no longer exists, only the discreteness in frequency remains, in fact, the real corridor is composed of this corridor in countless frequencies, and it is in this frequency that we walk. ”

Rosen listened to it for a long time, and only then did he suddenly wake up, isn't this the Fourier transformation, he had hung up the high number in college once in his last life, so he was impressed.

This method of linking the two domains through functions has indeed given Rosen a closer understanding of the world, and of course, a deeper understanding of the difficulty of the retake.

"So, how do we get out of here. ”

He wasn't interested in listening to the headache of math again, and instead asked directly about the end result.

"Now that you know the composition, it's very simple, just do one more Siegel inverse transformation of space. ”

With that, Karen immediately weaved several magic circles, and Lawson only felt that there seemed to be a buzzing sound in the air, and the surrounding fog immediately dissipated, and the strange feeling was no longer there, and the door between the silences was behind them.

"As I said, mages are self-confident people, and I'm no exception, and puzzles of this caliber are just a piece of cake for me. ”

Karen said with some pride, and looked ahead.

Indeed, a quaint gate stands in front of it, waiting to be opened.

But at the same time, between the three of them and the gate, there is another person.

His dark brown hair was tied into a ponytail at the back of his head, his shriveled face wore a pair of torn glasses, and his body was a plain and shabby robe, except for a thick book hanging from his waist.

His eyes were hollow, glowing with deep flames, and his face was expressionless, as if he was waiting for Rosen and the others to act.

"Charles Collins......

Of course, Rosen will not forget the name of the man who fought alongside him just a moment ago.

This is Vivien's Heroic Spirit, the existence of the Bard rank.
