Feng Yan simply sat cross-legged on the ground, holding his chin with his left hand, and still tapping the outside of his thigh with his right index finger, and began to think, while also inadvertently starting to talk to himself.
"Then reorganize all the tips that Clem just gave and extract some information about turning or turning back from these tips. Hmm... I thought of it. When I was about to set off, he was afraid that I would forget some questions I wanted to ask. , I came back to look for him and lost my way. I was told not to look back after entering the rainbow door. When the rainbow door is opened, I will be randomly transported to the outside of a long corridor. If I turn around and go back through the door I just came out of, I will not be able to look back. You can't go back to the corridor you just came out of, but you'll be teleported randomly..."
Feng Yan fell silent when he said this. He stared at the colors, numbers and U-turn marks and thought for a few seconds, then secretly said: "I understand, so that's what it means."
Feng Yan stood up, took out the white paper with the graffiti on it from the desk card, and put it into his pocket. Although he hadn't understood this reminder yet, it was definitely useful information. He chose to carry it with him first, and then He straightened his collar, came to Harlan Sanders' seat, looked around the conference table, and imagined in his mind the many audiences sitting on the chairs waiting for him to decipher the secret.
"Ahem, I know everyone must be waiting anxiously, so I will start explaining directly. Some students may not be able to keep up, so it's best to take notes."
This scene is also quite scary. A long-haired man wearing a hospital gown and a cloak on his shoulders speaks to an empty conference room. Thinking about it gives me goosebumps.
Feng Yan enthusiastically acted out and said happily: "The reasoning~ begins!!!"
“First of all, the clear prompt given by the system is to sort the four buckle pads in numerical order, and the final order of opening the door is purple, blue, cyan, and green. I emphasize here that this prompt is correct, but Just a hint. This puzzle is a bit difficult and convoluted. Then the second hint is about the U-turn mark. This is for sure, but it is difficult to combine the U-turn mark with colors and numbers. But after combining After Climb’s prompts, by connecting these three, everything can be easily solved. We will talk about this later.
First, we mark the seven colors of the rainbow as seven numbers from 1 to 7, which is: 1 red, 2 orange, 3 yellow, 4 green, 5 cyan, 6 blue, and 7 purple.
However, the colors and numbers in the plastic buckle pad we got do not match this mark. They are: 1 purple, 2 blue, 3 cyan, 4 green. Only the green number 4 matches it.
Then the combination of the two verifies the above statement, that is: the system prompts us to open the door of the corresponding color according to the numerical order inside the button pad, instead of asking us to open the door according to the order of the seven colors of the rainbow. If the system To open the door in the order of the seven colors of the rainbow, the numbers inside the button pad should match the numbers of the seven colors of the rainbow.
In fact, the system can also do this, but in this case, the puzzle will be simpler, and of course, there will no longer be a U-turn mark.
Next, let's review the three doors I just passed through. The colors of the three doors I opened were 'red, yellow, and green'. But after entering the door, I turned around and looked, and the color of the door I came out of was different. It didn’t match the color of the door I came in from, and even its position had changed. At first I thought it was also random, but after passing three doors, I figured out that the internal space of the door entering and exiting might be random, but the door’s The color and position are not random, but traceable.
I entered the red door in the upper left corner of the corridor. When I turned around, I saw the purple door. The position changed to the lower right corner of the corridor. The yellow door corresponded to the cyan door. The position was also changed. Only the green door corresponded. is green and its position remains unchanged.
Then let's simply do a connecting question. Red is the number 1, purple is the number 7, and the sum together is 8. Yellow represents the number 3, cyan represents the number 5, which when added together is still 8, and green represents 4, and when the same green is added, it is 4+4, which is still 8.
Based on this piece of information, it is not difficult to determine that the color of the entrance door and the color of the exit door are constant.
So let's go back to the prompts of the four buckle pads again. Please allow me to repeat them. The prompts of the buckle pads are: 1 purple, 2 blue, 3 cyan, 4 green.
So what should be the corresponding color on the other side of the purple door? Purple should correspond to red. The connection question above has already been explained, and it is calculated based on the color of the entrance and exit doors. The number representing red is '1'. Guess what, the number in the purple button pad is actually '1', blue corresponds to orange, and the number representing orange is '2'. Hey, it actually matches the number in the blue button pad. The numbers match up. Cyan corresponds to yellow, and the number representing yellow is 3. I checked it and it matched again. Green corresponds to green, and the number representing green is exactly 4. They all match up. This is how the numbers in the button pads match the colors.
Do you understand now? The U-turn sign means that after entering a door, we immediately turn around and open the door behind us. After entering the purple door, we turn around and enter the door we just came out of. At this time, it becomes a red door. After entering, we will find Strictly in the corridor. The second door in the sense is the blue door. After entering, immediately turn back and open the yellow door, and so on.
The U-turn mark gives us an unsteady hypothesis. Of course it is correct to use it forcefully, but it is just a little panicky. The connection results inferred from the corresponding colors of the numbers are an important basis to support this hypothesis and make it a fact. When you come to this conclusion, you don't have to panic, and you can open the door boldly and logically.
In fact, we have to open a total of 8 doors, but this is not contradictory or repetitive, because Clem has already reminded you before that after opening a door, if you go back through the door you just came out from behind, you will not go back to the door you just entered. That space, but randomly entered another space. In other words, based on one entry and exit, we actually only passed through the Rainbow Gate 4 times, but due to the random space mechanism of entry and exit, we entered 8 spaces. . "
Feng Yan took a deep breath and felt that the pores all over his body were opening. His cerebral cortex was very itchy while thinking and explaining just now. This was a sign of overthinking, but this kind of itch was very satisfying, making Feng Yan unable to stop.
Feng Yan looked around and said, "Now the students should know what to do next, right? get out of class is over!"
He kicked Harlan Sanders' seat down, then strode towards the purple door, then opened the purple door, and stepped in with one step. The white light flashed, and the door behind him immediately closed. He recovered After seeing it, he turned around without hesitation and said with his eyes closed: "Red!"
As soon as he opened his eyes, the door that had just automatically closed was indeed red. At the same time, his position also changed to looking down at the upper left corner. Feng Yan smiled proudly, snapped his fingers and immediately opened the red door, entered another corridor, and went straight to Blue door, after opening the blue door and stepping in, the white light was still dazzling. The door behind him closed automatically with a bang. Feng Yan turned around and made an emoticon gesture of "I'm optimistic about you", pointed at the door behind him and said: "Orange .”
The door behind him was orange. Feng Yan smiled proudly and said: "Although the puzzle is difficult, there is always a way to solve it. As long as it is a puzzle that can be solved, no matter how difficult it is, it is only a matter of time for me."
After opening the orange door, Feng Yan went straight to the green door and followed the example. After he entered and turned around, he guessed the color of the door again. Of course it was yellow. After entering the last green door, he turned around and paused slightly. The color was still correct, and the doors to enter and exit were both green, but when he opened it this time, the corridor inside was probably the butcher's territory, so he didn't rush to open it immediately, but was thinking about something.
