Doomsday female supporting role

Xia Qing held the wolf eye flashlight with one hand and pointed at the blood on the wall bricks with the other hand, saying, "Look at this bloody handprint." She didn't speak loudly, but all the C-National C team members heard it and gathered together.

Lu Shaoyan stood behind Xia Qing and looked carefully. The bloody handprint was about one meter away from the ground. The blood stain looked very fresh, and it should have been left not long ago. The handprint should be only half a piece. The handprint on the palm looked a circle smaller than that of an adult man. It should be a woman's handprint, and it is very likely that it was Gao Tong's.

He didn't see anything special, so he said, "Isn't it just half a bloody handprint? What's the good thing about it?"

Xia Qing patiently pointed to the section of the finger print again.

The green fox on the side said, "What do you mean is that there is only half of this handprint, and there should be another half. Where is the other half?"

Xia Qing walked forward while counting the bricks on the wall. Everyone made way for her until Xia Qing counted to ten points and she heard it.

When she shone with the spotlight, everyone saw the other half's handprint, which were five fingers. It was very consistent with the other half's handprint at the broken mouth.

Lu Shaoyan couldn't help but say, "How come this half of the handprint is here?"

Yes, why are you here?

"This shows that these two wall bricks should have been together, and the bricks on this wall can be moved. Therefore, the place where the mechanism is opened should be on this wall."

When everyone found the suspicious point, they had a direction. 16 people conducted a carpet-style search on the wall. Sure enough, they found several suspicious places and left marks on the wall tiles.

The bricks on the wall are arranged horizontally, and each brick is a rectangle of 300x500 in size. There is a dot on some bricks on this wall. The dot is just a shallow mark, which is difficult to identify with the naked eye and can only be felt with your hands. Moreover, the dots have different positions on the bricks, some are in the upper left corner, some are in the lower right corner, and some are in the middle of the rectangle.

Lu Shaoyan muttered in Xia Qing's ear, "Is this Braille?"

Xia Qing shook her head. She already had an idea in her mind, but she didn't know what to say.

At this time, Qinghu said, "This should be a password. Let me think about it, what is this called?" He frowned, as if he was trying to recall.

At this time, Ye Xicheng, who was beside him, spoke "Bird Cage Code."

The green fox slapped his hands and said, "That's right, it's a bird cage. Rectangular bricks are bird cages, and dots are birds. The birds jump around in the cage, but no matter what, they cannot leave their cage. This password is very ancient, and it is impossible to find out who invented it. The dots on the bricks represent different symbols at different positions, and each symbol represents different numbers or letters."

Xia Qing nodded. It turned out that in this world, this set of passwords is called the bird cage password. In her original world, this password is called the pigpen password, and there is a very high similarity between the two passwords.

Qinghu continued to introduce, "This set of passwords needs to be used in conjunction with the field grid or the nine-grid grid. There are three different positions in the middle of each grid." Here, Qinghu used a paratrooper knife to draw a field grid on an unmarked wall brick. The hardness of the surface of the wall brick was very high, leaving only two shallow traces.

Then, he poked three diagonally arranged dots in the grid in the upper left corner of the character Tian, ​​and if the three dots are connected, they happen to be an underline.

There were no stupid people standing here. Everyone understood the meaning of Qinghu at a glance. Even if Qinghu deliberately explained this set of passwords in Chinese, in fact, this set of passwords first came from the West. People in C may not have heard of it, but there should be many people who have heard of it in China and Ru.

So, there were two of them who were already writing and drawing while writing and starting to calculate.

Qinghu talked, and now he became more and more impressed. Several team members from other countries, who could understand C Mandarin, continued to surround him. He said more and more vigorously, "We have found a total of nine wall tiles marked with dots, so it is more likely to represent numbers. This wall is very likely to be a password wall of more than two digits.

Just looking at the position of the dots, we cannot tell whether this password is in line with the nine-cup grid or the Tian-cup grid.

But among the nine wall bricks we found, there are three groups of bricks, and the dots on them are the same, and the dots are in the upper left corner and the middle. Only one wall brick has a different position than the other eight pieces, and the dots are located in the lower right corner of the brick. Therefore, this set of passwords must be Tian Zige.

Next, what we need to determine is where the nine bricks are located on the square grid."

Qinghu said, and occasionally carved the brick with the word "Graphic" and calculated the password.

Xia Qing, Lin Fei and Lu Shaoyan stood aside and did not join the team of calculations.

Xia Qing was still staring at the bloody handprints on the wall in a daze. Lu Shaoyan, who was standing on her left, saw her wandering around the sky, couldn't help but say, "Little devil, you can't calculate the password on the wall in your mind, right?" After that, a pair of evil eyes stared at Xia Qing, with his eyes as if he was looking at a monster.

Xia Qing didn't look at him, shook her head and said, "No, I'm thinking about another thing."

"What are you thinking?" As soon as Xia Qing finished speaking, Ye Xicheng behind her asked.

He and Amber also stood aside, and participated in the calculation, and Qinghu alone was enough. Although he was considered a good writer, he was not as good as Qinghu in terms of reasoning and verification, so he didn't need to bother with it, and Amber thought so too.

Just now, when he was paying attention to Qinghu's calculations, he suddenly heard the conversation between Xia Qing and Lu Shaoyan. He knew that Xia Qing was quick-witted and not inferior to Qinghu, so he couldn't help asking.

Xia Qing said, "If the captain and the others were in the secret room now, I was wondering, under what circumstances did they open the secret room mechanism?

On this floor we did not find the body of the three-headed dog, so there are two situations: either it has left, or it and the captain and the others are in the secret room.

If it is the former situation, there are two possibilities. One is that the three-headed dog has not been killed. The other possibility is that during the fight, the captain and the others accidentally opened the mechanism. The captain and the others entered the secret room, and the three-headed dog was seriously injured and had no target, so they left here.

If it is the first possibility, the captain and the others do have time to crack the password wall. However, the three of them may not know the knowledge point of bird cage passwords. If they don’t know, the three of them will not be able to unlock the password anyway.

And the second possibility, or the situation where the captain and the three-headed dog are in the secret room, they have no time to crack the password.

Therefore, it is very likely to accidentally open the secret room mechanism.

Is there such a possibility? At the beginning, the three people fought with the three-headed dog. The crazy three-headed dog was amazing in combat. The three people lost. At this moment, Chi Li, who was covered in blood, quickly pressed her left hand on two wall bricks, and the door of the secret room opened."

After hearing Xia Qing's narrative, the four of them agreed with each other, but after all, it was just a hypothesis, and they believed that seeing was true.

Seeing the four people silent, Xia Qing continued, "I wonder if you have noticed that the location of these nine wall bricks is very high. Three of them are very above. Even the highest person in the team must jump up if he wants to touch these three bricks. In this way, those who want to enter the secret room must also bring a ladder.

Look at the two wall bricks with bloody handprints, now they are very far apart, more than the length of one person's arms stretching, and one person cannot touch these two bricks and stones at the same time.

If my assumption is true, the bird cage password is just a smoke bomb, and when you open this wall, you only need to press two bricks and stones at the same time. Then the remaining wall tiles that are convenient and accessible at the same time are only two pairs, respectively at the upper left and the lower right. The distance between these two pairs of wall tiles is more than the length of the arm span of ordinary people. So you can only choose one of two.

To add, when designing a password wall, designers will pay attention to its secrets, but at the same time they will also consider the practicality and rationality of use."

According to Xia Qing's assumption, three of the nine wall bricks are difficult to touch on the top, which is unreasonable and unpractical and can be ruled out.

The two wall tiles with bloody handprints, that is, the two that Gao Tong had contacted, moved after use, and the password changed. Now, these two wall tiles are very far apart, and there is a certain distance between them and other wall tiles.

In other words, bricks that cannot be pressed at the same time when a person enters the secret room are also eliminated.

In the end, there are only four wall tiles left, paired in pairs, with a certain distance between the two pairs, so the mechanism to open the password wall is among these two pairs of wall tiles.
