Thorns and bumps, but there is no hesitation.

(Text)

After drawing these cracks on the paper, you can use them to compare or stitch them together, which is very helpful for solving puzzles. Adventurers usually carry a notebook with them to write down important clues or graphics, so that they can easily view them when they need them.

Tang Xin looked at the crack patterns drawn on the paper, pondered, and didn't know what these figures meant for a while.

Ouyang Yu looked at his drawings from the side, not saying a word. I don't know if he has thought of a way, or is looking for a way, while the others are constantly searching for new clues on the rocks of the labyrinth.

Although everyone noticed the difference in the rocks but did not find a way to get out of here, it seems that the hope that they had found with great difficulty was suddenly disappointed, which is a bit disappointing.

"The cracks in these rocks are not exactly the same, but they are not much different." Changkong said.

Ouyang Yu suddenly thought of something, walked to Tang Xin's side, looked at the drawings in her hand and said, "These cracks should be fracture marks. ”

"Fracture marks?" Changkong looked at it carefully again and said, "Yes, why didn't I find out!" ”

"What do you say, what fractures? I don't understand at all. "It's as if you're listening to a book from heaven.

"Oh, no wonder you don't understand, this fracture mark is the term for maze design, and generally cracks will contain some important information, so there are all kinds of cracks, and what we see now is one of them, called fracture marks." Changkong pointed to the rock on the wall and said, "You see, these cracks all extend from one end of the rock to the other end of the rock in a straight line. Cracks like this are called fracture marks. ”

Ink Rou listened to Changkong say a bunch of words, but she still didn't understand it, but she didn't care if the crack on the rock was a fracture mark or not, she only cared when she could leave here.

"Is there any special significance to that fracture mark?" Tang Xin asked.

"Fracture marks generally only serve as a point, that is, let us know where to go."

Tang Xin looked at the fracture marks on the rock and asked, "How can this be seen where to go?" "It's as if the crack is cut across the surface of the rock.

"If you put a straight line in front of you, no one will know the direction, but if you change it slightly, it's completely different." Ouyang Yu said and drew a straight line on the paper. Then another two-day short line was added at one end of the straight line.

"Arrows!" Tang Xin said.

"That's right, as long as it's an arrow, anyone will know where to go." Ouyang Yu explained.

Tang Xin looked at the crack on the rock again: "You're right, but this crack doesn't have an arrow?" How can we know the specific direction? ”

"The arrow indicates that the direction is just one form of road sign, and it is okay if it is changed to another form, like this." Ouyang Yu drew on the paper again. He connected the two broken lines of the arrow, so that it became a triangle.

"Triangles can indeed point directions, but there are no triangles on the rocks?" Tang Xin still didn't understand what Ouyang Yu meant.

Tang Xin is right, there is no triangular pattern on the rock.

Ouyang Yu guessed that Tang Xin would definitely ask him this, so he continued to draw on the paper: "If I stretch this triangle, it may be easier to understand. ”

Ouyang Yu stretched the triangle and made it very narrow and narrow.

"I see!" Sky was the first to discover the secret.

"Isn't that understandable now? The triangle is stretched and becomes very narrow, like a line segment, but this line segment has a distinct characteristic, deep and shallow, and the back end of the triangle is obviously very deep. Ouyang Yu said.

In this way, the shallow place represents the top of the triangle, so that you can find the direction as well.

"Then we can just follow the direction pointed on this rock to find the mechanism of the stone gate!" Changkong said happily.

So under the command of Ouyang Yu, everyone continued to walk in the direction indicated on the rock.

After walking for a while, they stopped, and the crack mark on the rock pointed to this rock.

"This must be the mechanism of the stone gate." Ink said with certainty.

Murong Feng stepped forward and pressed the rock, and sure enough, the rock was pressed. A stone door appeared in front of Ouyang Yu and them, and then slowly opened.

"Great!! That's great!!! I've finally found the right stone door!! Changkong shouted happily.

"Alright, let's get out of here quickly." Ouyang Yu and the others walked into the stone gate, and in this way they returned to the original corridor, so that they were getting closer and closer to leaving this labyrinth.

"We're back in the same hallway! Just use the old method and we'll be able to get out of here! Changkong said.

"It doesn't seem that simple." Ouyang Yu looked at the stone gate in front of him and said. His expression was very solemn, as if he had encountered some problem.

"What's the matter, didn't you discover this method? And we also used this method to go back to the original hallway, why are you not confident? "Ink Rou thought it was weird.

Ouyang Yu did not speak.

"What the hell is going on?"

"How so! How so! Changkong also shouted in shock.

"What's wrong? What the hell is wrong with you guys? Haven't they all found a way out of here? Tang Xin asked inexplicably.

"No, not at all." Changkong said to himself.

"Tell me what's going on?" Mo Rou asked anxiously on the side.

"The cracks in the rocks have all changed, they are not fractures at all, all the clues are broken, they are all broken...... "Changkong said in despair.

Ouyang Yu and the others found the mechanism of the stone gate through the crack in the rock of the corridor, but what they didn't expect was that when they returned to the previous corridor, they found that the crack on the rock was no longer the fracture mark they had seen before, so they could not find the location of the mechanism through the previous method. As Changkong said, all the clues were broken, Ouyang Yu's face was very solemn, he thought about something carefully, and did not speak.

Everyone didn't say a word, and in this way, the success that was originally close at hand was suddenly far away from the end of the world.
