Thorns and bumps, but there is no hesitation.

"Cut, what's the big deal." Murong Feng said.

"Why do you think I'm here, but what about you? And why are you here, and it's not just you, it's every single one of you. Everyone knows that there are many dangers in the ancient labyrinth, but you have not given up, and I think you all have your own reasons to go on. Isn't it? Ouyang Yu looked at Murong Feng and then at everyone.

This sentence spoke to everyone's heart, and everyone did not speak.

"In that case, we all have the same purpose, and we just need to know what it is, isn't it?" Ouyang Yu asked rhetorically.

"Don't be so surprised, what is my purpose, I just want to see what the ancient labyrinth looks like." Murong Feng replied, "Okay, since you don't want to say it, forget it." ”

In fact, everyone here has their own ideas, since their purpose is the same, the rest is not important, the most important thing now is to find a way to get out of here quickly.

"If you're in the mood to chat here, you might as well think about how we're going to get out of here now." Ink Rou said.

"yes, Changkong, how are you reading your book? Is there a way to do it? Tang Xin deliberately opened the topic.

"Come on, I think it's in these chapters." Sky replied.

Murong Feng walked away and continued to look for new clues, while Ouyang Yu still took the few dustless books and studied them carefully.

After an argument, everyone began to busily search for clues, and the door to the reference room was still closed.

Changkong suddenly found the answer he wanted for Zhao: "Mirror Array..."

When he laughed, he got lost in the strange array, and everyone else walked out smoothly, only he stayed in it alone, Changkong felt the same no matter how he walked, just when he was at a loss, he suddenly remembered the birthday gift his grandfather gave him, and soon he found the answer, the so-called mirror array is that the person who created the maze created two identical mazes in front of the person, and these two identical mazes are connected in only one place, but there is only one exit from the maze, in this case, When entering the labyrinth, Changkong took out a pen and paper again, drew the path he had traveled on it, and sure enough, he got two almost identical labyrinths.

And the only difference is the exit from the labyrinth, when Changkong came out, it was already dark, everyone had already dispersed, only Grandpa was waiting for Xiao Changkong. “

"How's it going, isn't the maze hard?" Grandpa asked.

"It's not difficult, I'll definitely build a maze even more powerful than this." Changkong said with a smile.

If it were someone else, he would definitely sneer: "I can't help myself." But Grandpa didn't laugh at Changkong, but said very seriously: "I think you must be able to." ”

"Really?" Sky was overjoyed.

Changkong stood up and said, "I've found the answer!! ”

"Really? How the hell can we get out? Tang Xin asked curiously.

"It's a mirror array!" Changkong's words are not understood by everyone.

"What is a mirror array?" Ink Rou asked.

"It's actually very simple, it's that the place where we are is a symmetrical place, and you look at every row of bookshelves here, one left and one right."

"Perfect symmetry? But these bookshelves aren't symmetrical, right? On the contrary, the two sides have different directions. Tang Xin looked at the bookshelf and said.

Tang Xin is not wrong, these bookshelves are not aligned left and right, a little to the left, some to the left, some to the oblique, in short, they are different.

"I see!" Mo Rongfeng suddenly understood something. He walked to the side of the bookshelf and said, "You see, I found it earlier, and these bookshelves have obvious traces of pulling, so I think before this, these bookshelves should be completely symmetrical as Changkong said." ”

"In that case, let's move the position of this bookshelf so that we can get out of here?" Ink Rou asked.

"That's probably it." After Murong Feng finished speaking, he began to move the position of the bookshelf.

Soon, with everyone's efforts, the bookshelves on both sides were soon symmetrical.

"Okay, but why didn't there be any reaction? What the hell is going on? Ink asked softly.

"That's right, isn't there?" Changkong flipped through the book in his hand and said, "That's what the book says." ”

Obviously, the method that Changkong said did not have any effect, and the bookshelves on both sides were neatly arranged, but the door of the reference room still did not open.

"Maybe it's not aligned there...," Changkong said as he checked the position of the bookshelves.

"I think it's just that the method you said is not right at all, what kind of mirror array, even if these bookshelves are aligned, it will be useless, and it will be useless." Seeing that there was no hope, Ink Rou said angrily.

"Don't talk about Changkong like that, he's also trying to find a way to get out of here, if you're so powerful, can you find a way to help us get out of here?" Tang Xin asked rhetorically.

Mo Rou couldn't help everyone get out of here, so she had to stop talking.

"Don't make a noise, everyone!!" At this time, Ouyang Yu on the side finally spoke.

Everyone fell silent. Looking at Ouyang Yu.

"Maybe what Changkong said is not wrong, but we are wrong." Ouyang Yu said.

"Are we wrong? Are we really wrong? Aren't these bookshelves neatly arranged? Ink asked.

"The so-called mirror array, it is worth that the two sides should be exactly the same, not just the position of the bookshelf." Ouyang Yu said and walked to the front of the bookshelf: "You don't know if you have noticed one thing, the order of the bookshelves on the left and right sides is actually exactly the same. ”

"Really! You don't say that we didn't pay attention at all. ”

But it's no wonder that there is no light here, and everyone is looking for clues in a dark place, so it is inevitable that there will be some omissions.

"If the books on the shelves are in the same order, why hasn't the door to the library been opened?" Ink Rou continued to ask.

"The answer is actually quite simple." Ouyang Yu said and put the dustless books just now in front of him and continued: "The position of these books is asymmetrical. ”

"I've only found half of these books, so how can they be symmetrical? If you want to match, you need at least two copies, right? ”
