[Chapter 41, Prime Number Labyrinth 03]

According to Jiang Pingce's instructions, the three of Yue Xingwen continued to collect the twin prime cards on this floor. As new rooms were opened, the interference path of this floor was gradually and completely displayed on the maze map in Jiang Pingce's hands.

It was not until all the rooms were searched that Jiang Pingce looked carefully at the labyrinth map——

There are 48 rooms drawn on the drawing. The main road is arranged like a "cross", and there are many fork roads around. There are four elevators in the rooms at the four ends of the upper, lower, left and right. Access to other floors.

There are a total of 192 digital cards in this layer, and all the twin prime numbers have been circled by Jiang Pingce? There are 48 sets of 96 twin prime number cards collected so far. That is, each room has a pair of twin primes.

Among them, the road that Xingwen took had many forks, and 16 pairs were collected; the direction Ke Shaobin and Liu Zhaoqing were walking frequently encountered dead ends, and 8 pairs were collected each; Jiang Pingce collected 16 pairs.

Assuming that this three-dimensional maze is a three-story building with the same structure of the upper, middle and lower floors, Jiang Pingce's reasoning will become much simpler. But in case it is not the same as the floor structure, the path of the maze will be more complicated.

3 hours and 40 minutes left in the countdown. That is to say, after checking all 48 rooms on this floor and calculating 192 numbers, Jiang Pingce only spent 20 minutes.

Since Jiang Pingce did not give any instructions, the three stopped to wait for news from the research group.

After a while, Jiang Pingce said, "Brother Liu goes back 5 rooms in a straight line, finds the door 11073, and takes the elevator downstairs." "Young Master Ke goes out from the door 13011 and walks 4 rooms straight to the right. Take the elevator downstairs."

The two immediately followed Jiang Pingce's instructions and quickly found a room.

Liu Zhaoqing had been in the maze for 20 minutes, and he had already lost his head. He couldn't tell the direction, let alone remember which room had an elevator. But he followed Jiang Pingce's advice and walked straight back 5 rooms. Sure enough, he saw the number 11073 was posted on the door on the right. He pushed the door open - it was the elevator room!

They rammed like headless flies in the labyrinth, but Jiang Pingce seemed to be standing in the perspective of God, who could clearly see their moving paths and make the most accurate instructions.

Liu Zhaoqing was so impressed that he couldn't bear to live in the research group channel and type: "Fantastic, I'm going downstairs!"

Ke Shaobin also went downstairs as suggested by Jiang Pingce.

Yue Xingwen asked, "What about me?"

Jiang Pingce said: "Xingwen went in through gate 12077, walked straight ahead for five rooms, and took the elevator upstairs."

Yue Xingwen was stunned: "I'm going upstairs, not going downstairs?"

Jiang Pingce explained: "Save time. You go upstairs with me, Senior Brother and Ke Shao go downstairs."

The labyrinth on the third floor, the middle floor has been searched, Jiang Pingce arranged for Liu Zhaoqing and Ke Shaobin to go to the lower floor, he and Yue Xingwen go to the upper floor, and the upper and lower floors can be investigated at the same time.

This way, no, but four people, four paths, still on two different planes!

If it's not spatial imagination and solid geometry, it's going to be a complete mess. The three teammates were obviously very confident in Jiang Pingce and did not raise any questions.

Jiang Pingce separated two pieces of paper and began to draw the map of the lower and upper floors. While typing quickly on the research group channel, he said, "It's still the old rule. After entering the room, count the number clockwise."

Liu Zhaoqing quickly reported four numbers: "101277, 101279, 101281, 101283."

Yue Xingwen couldn't help but feel dizzy when he looked at these numbers. Judging by his mathematical common sense, the numbers with the mantissa 0, 2, 4, 6, and 8 are definitely not prime numbers, because they are divisible by 2. The mantissa is 5, which is usually divisible by 5. It is for this reason that the cards in the maze rarely have the simple question of "it's not a prime number at first sight", and at the end, all of them end with 1, 3, 7, and 9.

The four numbers listed by Liu Zhaoqing all look like prime numbers, and the difference between the two is 2, which meets the conditions of "twin prime numbers". Which two should I choose?

In order to save time, Jiang Pingce directly reported the mantissa: "Choose 79, 81, and enter the door of 81."

Liu Zhaoqing feels that his IQ has been crushed!

Ask him to calculate these four numbers. He must try ÷7, ÷3, ÷11, etc. one by one. For a six-digit number like 101277, it will take at least one minute to calculate the answer. But doesn't Jiang Pingce know what method to use? How can the six-digit answer be reported instantly?

This is simply the strongest brain comparable to a computer, right? !

Ke Shaobin also encountered six figures: "107507, 107509, 107511, 107513."

Jiang Pingce said: "Take 07 and 09, and go to door 09."

Ke Shaobin stretched out his hand and took the twin prime number card on the door - also a science student, Jiang Pingce was really ashamed that he could count so fast.

Yue Xingwen has completely given up thinking. After entering the room, he lost the numbers on the research group channel: "111117, 111119, 111121, 111123."

Jiang Pingce answered quickly: "Take the tail numbers 19 and 21, and go to gate 21."

The exploration of the upper and lower layers officially began.

The research group channel kept flashing information - all three people were reporting the number, and Jiang Pingce was reporting the answer.

The surroundings were extremely quiet, and the channel of the research group was swiped by a large number of numbers, which made people dazzled.

But Jiang Pingce's instructions were always clear and concise. He would tell his teammates which two twin prime cards to take and which door to open. Even if the three teammates are elementary school students, under his precise instructions, they will not make mistakes.

After walking through several rooms in a row, the difficulty increases again.

Yuexingwen reported four numbers: "147677, 147679, 147681, 147683"

He thought that Jiang Pingce would let him win a pair of twin prime cards as before. However, to his surprise, Jiang Pingce suddenly said: "There are no twin prime cards here, go through the door ending in 77."

Yue Xingwen walked into the door and found that the two cards in the room had been removed.

If two cards are removed, it means that he has come to this room? Yue Xingwen immediately told Jiang Pingce what he found: "Two cards were taken."

Jiang Pingce: "Go back and go to Gate 79."

Yue Xingwen: "There are still two cards that have been taken."

Jiang Pingce suddenly fell into deep thought.

Yue Xingwen was a little worried - the complexity of this maze was beyond his imagination. He obviously did not turn back, but he was walking, how did he come to the room he just went to? Like a "ghost hitting the wall" and going back to the origin?

Yue Xingwen was puzzled: "What is the structure of this maze, I seem to have been to the rooms around this room?"

Downstairs, Liu Zhaoqing and Ke Shaobin saw that Yue Xingwen was in trouble, and stopped at the same time to give Jiang Pingce some time to digest the information and clarify his thoughts.

The three were waiting for Jiang Pingce's response.

After a while, Jiang Pingce said: "The rooms on the upper floor are arranged in countless "field" shapes, and the rooms are connected to each other. The room that Xingwen just discovered without twin prime numbers should be the center of the entire floor."

He paused and said, "Xingwen, don't move, I'll come to find you. Senior brother and Master Ke wait a moment."

The three stood obediently in the room and did not move. After about half a minute, a door on the right side of Yue Xingwen was suddenly pushed open.

Jiang Pingce walked in quickly?

The boy was tall, wearing simple and clean black trousers and a white shirt, with a belt around his waist, which set off his long, straight legs. The surrounding walls are like a deep starry sky, and the walls are full of stars. When he pushed the door in from the side, it was as if he was walking from the starry sky.

Yue Xingwen turned his head, met him? With his calm eyes, he suddenly felt very at ease.

This labyrinth, no matter how complicated it is, with Ah Ce there, what's there to worry about?

Yue Xingwen greeted him with a bright smile and went forward: "In such a chaotic maze, how could you find me in 1 minute?"

Jiang Pingce's lips curved slightly, and his gaze towards Yue Xingwen was very gentle: "It seems? My inference is correct, this floor should be a 'Tian' type of 49 rooms with horizontal seven and vertical seven. The maze structure, the room we are in now, is the most central room of the 7x7 huge square maze."

Yue Xingwen seemed to understand, but patted Jiang Pingce's shoulder lightly: "Amazing! My brain has become a mess, how did you analyze it?" He looked down at Jiang Pingce The map in hand...

It's so scary!

The three sheets of paper represent the maps of the upper, middle, and lower floors, respectively. The asterisks represent the elevators. The densely packed square rooms are connected together and marked with numerous numbers and directional arrows.

Yue Xingwen found that he couldn't even read the map? He understood...

Jiang Pingce said: "It's more complicated to explain. Let's find the prime numbers first, hurry up and finish the test, and I'll analyze it for you after we go out."

Yue Xingwen agreed: "Yes! The clearance time of the labyrinth must be linked to the test score. I don't think I can understand it if you explain it now. What should I do next?"

Jiang Pingce pointed to the middle of the map and said, "Our current position is the center of the upper labyrinth. If you look for the way in the opposite direction from the center, you won't miss any room. You go through the door on the right. , I'll go to the left."

Yue Xingwen nodded, and Jiang Pingce continued: "After entering the door on the right, walk three rooms in a row, turn left, and report the number to me."

Yue Xingwen turned around and walked over, separating from Jiang Pingce.

Jiang Pingce said on the research group channel: "Ke Shao and senior brother continue."

The two people on the lower floor continued to investigate, and soon, Liu Zhaoqing also met a room, and there appeared four numbers that looked like prime numbers, but were actually not prime numbers at all.

Jiang Pingce said: "Senior brother's room does not have a twin prime number either, it should be the center of the lower floor. Master Ke, go out through the door directly in front of your current room, walk three rooms in a row, then turn left to see if you can ? Can meet with senior brother."

Ke Shaobin did as he did.

After a while, the two really typed on the research group channel: "Meeting!"

Liu Zhaoqing: "...Fantastic, how did you make us meet in the labyrinth?"

Jiang Pingce didn't have time to explain, so he simply said: "The upper and lower structures are the same. Now start to find the way as fast as possible. Senior brother goes to the door at 171083, Ke Shao goes to 171081, and each person walks straight forward three rooms, reporting the number along the way. ."

After the two of them walked through three rooms, Jiang Pingce continued, "Senior brother turn left, Ke Shao turns right, and report the number."

"Senior brother took 192191 and 192193, and walked straight to the right for seven rooms."

"Young Master Ke turned to the left and went straight forward seven rooms..."

The three almost became "card-finding tools", and Jiang Pingce could even accurately grasp their orientation!

Liu Zhaoqing walked 7 rooms in a straight line and found that the road ahead was a dead end. The same was true for Ke Shaobin and Yue Xingwen. Don't you know how Jiang Pingce figured it out? The end of the 7 rooms is a dead road?

If there is a camera from the perspective of God at this time, you can find that the huge three-dimensional labyrinth is like a three-story structure full of square rooms. Under the command of Jiang Pingce, they make S-shaped shapes in four directions exercise?……

Such a search will not miss a single room.

After a while, Yue Xingwen suddenly said: "I saw a room with an elevator in it, and I can only go up."

Jiang Pingce said: "Xingwen, what you found is the export."

Yue Xingwen: "..."

Find an exit, at least pass this class. He glanced at the countdown in the upper right corner. They only spent 1 hour and 20 minutes of the 4 hours of exam time.

Jiang Pingce said: "Senior brother, go three rooms forward, turn left and go two rooms, take the elevator to go up two floors, go forward five, and then turn right." "Ke Shao, right three, straight four, take the elevator? Two floors, go forward four times and turn left."

He said that these are like tongue twisters. It can be seen that Jiang Pingce already has a complete three-dimensional labyrinth map in his hand, so that he can accurately indicate his teammates' actions and routes.

After a while, Jiang Pingce came again to the room where Yue Xingwen was.

It didn't take long for Liu Zhaoqing and Ke Shaobin to come accurately too? They arrived in this room to meet.

The three looked at each other, shocked in their hearts, not knowing what to say for a while.

Yue Xingwen asked, "How many pairs of twin primes did you collect in total?"

Don't Jiang Pingce need to count the cards in his teammates' hands and report the number directly: "144 pairs, all together. Let's go."

He pressed the shutter button, and the three followed him into the elevator. This elevator can only go up. There was a sound of "ding" soon, and the moment the elevator stopped, a mechanical voice sounded in the ears of the four of them at the same time: "Congratulations to the c-183 research group for successfully leaving the prime number maze. It took 1 hour and 30 minutes to collect the twin prime numbers. 288. The exam is over, the points are being settled..."

Remember the night before? Yue Xingwen also joked with Jiang Pingce: "If there is Pingce, just get full marks."

I didn't expect it? didn't expect this joke to come true——

Jiang Pingce really single-handedly took three teammates to get the amazing result of clearing the customs with full marks! w, please keep in mind:,
