[Smart Library-06]
From the dormitory corridor to the dormitory management center, everyone teleported back and forth a total of 12 times, and only then did they find all four teammates. Ke Shaobin's laptop recorded the coordinate data of each space. Jiang Pingce looked at the data on the screen and said, "Build a three-dimensional coordinate system model and see."
Ke Shaobin is very familiar with modeling, and soon he simulated a three-dimensional coordinate system in the computer, and placed the space he had visited before in this three-dimensional coordinate system according to the corresponding coordinate range.
Everyone was surprised to find that these spaces are like square boxes, suspended on the same level, and the arrangement seems to be irregular.
The "box" at the very center, they haven't found at all.
Jiang Pingce pointed to the three-dimensional modeling graphics on the screen: "Look, the spaces of these dormitory management centers are not adjacent. Each one exists independently, but the distance between them is fixed."
Ke Shaobin also discovered this rule. He quickly numbered all the spaces and said, "There is a 3-meter missing coordinate data between space 1 and space 2, and the same is true for other spaces."
Jiang Pingce thought about it and said, "The missing 3x3 meter area should be the elevator shaft that was bombed."
This is what he calculated based on the distance. Before the library did not activate the emergency system to blow up the elevator shaft, they could usually take the elevator directly to the dormitory management center. The position of the elevator shaft just matched the missing area in the model. Whether this is the case or not, let Xiaotu test the elevator shaft near the dormitory management center.
Ke Shaobin excitedly said: "Let's go and verify it!" He turned back and swept the eight corridors outside the dormitory management center and asked, "Which portal to go to?"
Yue Xingwen said: "I guess one, go to c to try."
Anyway, it's luck, with a one-eighth probability, any one will do.
Everyone followed Ke Shaobin into door C, then turned around and entered the dormitory management center through another exit of the corridor. Sure enough, they were teleported to a new space, and the robot sensed their presence and immediately launched an attack. Lin Manluo reacted very quickly, the vine in her hand was instantly thrown out, and the two robots were thrown out!
At the same time, Ke Shaobin took the time to take a small picture to the vicinity of the bombed elevator shaft, and detected the precise coordinates here. And enter the new data into the modeling graphics on the laptop.
Ke Shaobin's eyes lit up: "Sure enough, the missing coordinate is the elevator shaft!"
He glanced at Jiang Pingce, who said in a low voice, "It seems that there is a dormitory center in front, back, left, and right of each elevator shaft."
Ke Shaobin said excitedly: "So, the structure of the -3rd floor dormitory area is really like an unfolding flower. The dormitory management center is the 'flower area'. There are elevator shafts between the stamens and the stamens. Each elevator can go to four Open the door in the direction and send students to different spaces. The student dormitory area is the outer 'petal', and there is also an elevator shaft at the end of the petal area, which can send students directly to the dormitory corridor, and can also lead to other floors."
Jiang Pingce nodded and said: "Well, the petals and the stamens can be reached through the portal. Every time you pass the portal, the space will change. It can be understood that the stamen area and the petal area are separate systems, each according to certain rules. Rotation. For example, the No. 1 stamen originally corresponds to corridor a, but after rotation, it may correspond to corridor c, which is why the spatial coordinates of the dormitory area will change after each teleportation."
After Ke Shaobin and Jiang Pingce's sorting and analysis, everyone finally had a clear understanding of the structure of the -3rd floor dormitory area!
Xu Yishen concluded: "I see, it's like a blooming sunflower. The disc in the middle and the petals on the periphery are rotating according to different rules. What we need to do now is to find the center of the whole flower?"
Jiang Pingce nodded: "That's right."
Since the correspondence between the central area and the peripheral area is constantly changing, if they try to find the middle point through luck and continuous transmission, the probability of hitting it will be very low.
But with accurate data analysis, it's easy to look again.
Jiang Pingce quickly calculated the data: "The coordinates of this elevator shaft are (10, -50, -3). From the elevator shaft here, 10 meters forward and 50 meters to the right, you can reach (0, 0, -3). 3) the central space.”
-3 represents the floor, the data is fixed. The first two numbers are the coordinates of the x-axis and y-axis.
Jiang Pingce said: "Because the space in the central area and the dormitory area has been changing, it is impossible to transfer directly. However, the location of the elevator shaft is fixed, and we can directly change positions from the elevator shaft."
The elevator shaft has been blown up and there is no place for them. But they have Zhang Xiaonian.
Yue Xingwen looked back at Zhang Xiaonian and said, "Junior brother, build a concrete floor at the position of the elevator shaft, everyone will hurry up and get Qin Lu to change positions."
Zhang Xiaonian immediately stepped forward, raised his right hand, and created a concrete floor in the blasted elevator shaft.
The crowd walked over quickly. Since the elevator shaft had just been blown up and the smoke inside had not dissipated, everyone was so choked that they couldn't help coughing and covered their mouths and noses.
The next moment, Qin Lu took out the globe, quickly entered data on it, and said in a low voice, "10 meters ahead, 50 meters to the right, and the plates are reversed!"
With a sudden flash in front of them, they switched positions to another space.
This is still a square area, and the area is exactly the same as those of the dormitory management centers just now. However, the place looked empty at first glance, there was no dormitory robot, and there was no tablet computer service area used by other dormitory centers for dormitory registration.
They seemed to come to a closed empty box.
Everyone looked at each other.
Jiang Pingce frowned and said to Ke Shaobin, "Check if the coordinates are correct."
Ke Shaobin immediately turned on Xiaotu's monitoring skills, and a row of data quickly appeared on Xiaotu's screen. At this time, the coordinates of the 12 of them all became (0, 0, -3) - they finally came to the most central position of the -3 floor dormitory floor.
But as the small graph reported the data, the familiar mechanical sound sounded the alarm: "Library powerhouse, no entry!"
This crisp children's voice clearly comes from the small picture.
Ke Shaobin looked down and found that Xiaotu's screen and indicator light turned off at the same time, as if it was turned off. He tried to press Xiaotu's head, but there was no response when restarting.
Ke Shaobin scratched his head in confusion: "What do you mean by the center of the library? The small pictures can't be turned on."
Yue Xingwen thought about it carefully, and suddenly his eyes lit up: "Could we have entered the fire escape of the library building by mistake?! General high-rise buildings will leave a fire escape, which is usually not used, and can escape at critical moments."
Jiang Pingce looked at him and said in agreement, "If that's the case, we've probably found the right way to leave the library, which is the stairwell."
When everyone heard this, their faces showed joy.
All the elevator shafts were completely blown up. They rely on gravity, coordinate system and other skills, and the method of artificially controlling the elevator lift is no longer feasible. However, there is another way to escape—stairs!
In the event of an accident in a high-rise building, it is usually not possible to take the elevator, but to escape through the stairs.
However, when everyone first met, they couldn't find where the stairs were. Usually, they use the elevator to go in and out of various floors of the library, and they have never seen the stairwell.
Perhaps, the stairwell is hidden in this most central hidden location
Thinking of this, Yue Xingwen immediately said: "Let's look around to see if there is a hidden secret door!"
The 12 immediately dispersed, looking around the "box", banging against the walls.
After a while, Qin Lu's excited voice came from behind: "There is a secret door on this wall, painted the same color as the wall."
The next moment, Liu Zhaoqing on the right also said, "There is a door on this wall."
Zhang Xiaonian said: "I found it here too!"
Zhuo Feng looked at the secret door in front of him: "So, there are secret doors on the four walls in the center?"
Jiang Pingce said, "Push it away and take a look."
The four of them pushed open the door in front of them at the same time—behind the door, there was an identical stairwell with the words "fire exit" written on it.
Ke Shaobin adjusted his glasses and quickly changed the three-dimensional model in his laptop, saying, "The center of this library building is actually a huge patio. The east, west, south, and north directions of the patio are four The stairwell can lead to different floors. Usually, this patio is closed, so we have been in the library for more than two months and have never seen the stairs.”
Xin Yan walked to his side, looked at the model in the computer, and said, "According to common sense, it is possible to escape the building through the stairwell. But, on which floor is the exit of the library building?"
Zhang Xiaonian thought for a moment and said, "Usually, the exit of a high-rise building is on the ground level on the first floor, but the structure of this library building is more complicated, with 6 floors underground and 13 floors above ground. The building goes to the academy on the twelfth floor, so I personally think that the exit is likely to be on the top floor."
Since coming to the library, they have gone from the medical school on the first floor to the School of Humanities on the 12th floor, and the last floor is the School of Computer Science on the 13th floor.
The possibility of the exit on the thirteenth floor is indeed very high, but it does not rule out that the first floor is a simple version of the exit.
Yue Xingwen and Jiang Pingce looked at each other and said, "I suggest climbing to the first floor to have a look. If there is no exit, just keep going up to the top floor."
Jiang Pingce nodded: "Well. Team, or together?"
After all, there are four elevators in the east, south, west, and north. According to the library's temperament, the four cannot be exactly the same, and there must be pits in them.
Yue Xingwen looked at his teammates: "What do you think?"
Liu Zhaoqing said: "I suggest a team. Of the four elevators, only one is correct. The other three are very likely to be pits left by the library for intruders."
Brother Liu has always firmly believed in the principle of "libraries do not teach martial arts".
Zhuo Feng also agreed: "It's too crowded for 12 people to walk together, and the stairs are narrow. If you are surrounded by front and rear, it will be troublesome to escape. It is more appropriate to divide into 2 teams. There is a 50-50 chance of hitting the right road. If it doesn't work, try again."
Four exits into four teams is the fastest, but the risk is also the greatest. After all, their escape skills are limited, and some teams may not have the ability to protect themselves in case of danger.
Thinking of this, Yue Xingwen simply said: "I, Pingce, Senior Brother Zhuo, Senior Sister Lin, Senior Sister Lan, Xiaonian First Team, Pingce will lead the team. Ke Shaobin, Xin Yan, Qin Lu, Qin Miao, Xu Senior Brother Liu The senior team is led by Ke Shaobin. We go left, you go right, and the LAN channel can be contacted at any time!"
The crowd was simply divided into two groups, and after saying goodbye to each other, they quickly entered the stairwell and climbed up quickly.
