Seeing that there was nothing else that could attract attention in the room, Ling Zhi turned his attention back to the short-haired girl again and asked the question he had been wondering about for a long time:
"Well, Shi Yan, tell me, how did you find me at that time? How did you know that I was playing 'One Billiards'?"
The short-haired girl's face was obviously flustered. She turned her head, not daring to look at Ling Zhi, and said to the other wall:
"Uh, um, I... I knew it from Brother Feng. I entered 'Youth No. 8' and saw that you were not there. I recognized your two roommates. They told me that you were next door, so I came over.
ah."
"Oh, that's how it is."
It makes sense. The short-haired girl is not familiar with the two Feng brothers. If she comes, there is no reason to wait for him at "Youth No. 8".
"Sigh, but speaking of it, if you could have called Brother Feng and the others over at that time and there were more people, maybe the situation would have been different. It would have been too reckless for you to just rush in."
Seeing that the girl with short hair wanted to argue immediately, Ling Zhi immediately answered:
"Uh, but I'm still very happy that you can... you can find me as soon as possible. Your action of kicking the door open was so cool, did you know..."
"Hahaha, of course. When I saw you inside, how could I resist looking for you? I didn't think much about it at all."
"Hmm, thank you, thank you for doing this. But it's okay. Calling Brother Feng and the others here will probably inevitably lead to a fierce battle. Now they may be able to think of other ways outside, so as not to implicate them."
"Too."
Ling Zhi repeated his analysis of the past hour and the current situation of the two of them. Zhao Shiyan felt that it was right. At the end, she asked again:
"But speaking of which, why did those people set up this game?"
As he spoke, he pointed at the computer.
Ling Zhi thought about it and said tentatively:
"I have an idea, but it may not be right. Please listen and see if it makes sense."
"It's okay, Ling Zhi, just tell me."
"That's right. It is said that there is a game theory in economics, which mentions a model called the prisoner's dilemma."
"The prisoner's dilemma is about putting two prisoners and accomplices in two cells, and each person cannot communicate with the other person."
"In this case, everyone has two choices: confess or remain silent."
"If both men confess and expose each other, then the police have sufficient evidence and each will be imprisoned for 5 years."
"If one person confesses and the other person remains silent, then the person who confessed will get merit and be released on the spot, while the person who kept silent will be imprisoned for 20 years."
"If both of them remain silent, then the police will have no evidence and each will be released after one year in prison."
Zhao Shiyan nodded thoughtfully and responded:
"I understand, Ling Zhi, you mean that we are like two prisoners, right? I understand this. If we choose b at the same time, it is equivalent to being silent at the same time. If we choose other options..."
"If we didn't all choose b, I don't know what would have happened. I just relied on the clue that we would be released after one hour and thought of this scene in game theory."
"If we all choose A, we don't necessarily have to be locked up for 5 hours. However, with the bad taste of those people, I'm afraid if we all choose A, the ending will not be better than if we all choose B."
The short-haired girl immediately shook her head and continued:
"That's impossible. We can't all choose A, because I will definitely choose B. In this case, if you choose A, you will be able to come out immediately. You will definitely find a way to save me by then.
hey-hey!"
Ling Zhi was a little surprised. Doesn't this girl care that he chose the self-interested option? However, according to Ling Zhi's own temperament, he would not choose the self-interested option, but this did not prevent him from feeling grateful for the short-haired girl's trust in him.
move.
"Haha, thank you for trusting me so much. You think too highly of me. Even if I come out, with the strength of this door, I may not be able to do anything. But I will definitely find a way and do everything possible to save you!"
The short-haired girl smiled sweetly. She had no doubts about Ling Zhi's statement.
"Speaking of it, the best solution to the prisoner's dilemma is for both people to release goodwill at the same time. Even if one of them chooses a self-interested option, it will be detrimental to the overall situation."
"Economists put forward this theory to remind people not to just consider immediate benefits when making choices, otherwise it will still be detrimental to themselves in the long run."
"Just like now, to put it another way, even if I come out first, it might not be easy for me to escape from this hall by myself. And we don't know how many people are waiting for us outside.
I have a better chance of winning if I'm with you, haha!"
"Yeah, that's right. If we work together, nothing can stop us, right?"
"that is……"
The boy and girl looked at each other and smiled, and the laughter resounded in the silent hall.
Although the two are still in trouble, they believe that as long as their hearts stick together tightly, they can solve all problems.
…
After the two talked, they both agreed that no matter what happened, they still had to find a way to save themselves.
The two of them walked out of the house, came to the hall, and began to carefully look at the furnishings in the hall.
The lobby still has no windows and is not very big. It is 40 square meters. There is a small bathroom taking up about 2 square meters. The rest of the hall is very empty.
There were some things piled up in the corner. The two of them walked over and took a look. They were all simple foods such as bottled water and compressed biscuits.
There was a door at the end of the hall. Ling Zhi walked over and pushed it. As expected, it couldn't be opened.
However, when he looked closely at the door lock, he discovered that it was actually a combination lock!
The password lock has 4 digits, and each digit can enter 10 numbers from 0-9.
"What the hell is this! These people arrested two people here just to escape from the room?"
Ling Zhi once again had a new understanding of the bad taste of those people.
Zhao Shiyan also went over to observe and complained:
"It's just, it's so boring!"
However, complaints are complaints, and the two of them cannot sit still and wait for death. As for the purpose of those people doing this, they will naturally have their own concerns after they go out.
If you want to open the door, based on your experience in the house, there should be clues nearby.
Ling Zhi looked around the hall again, trying to find if he had missed any clues.
Zhao Shiyan was rummaging through the food to see if there was anything hidden.
This hall is also illuminated by an incandescent lamp. The walls are the same as in the house, without a single scratch, and are shockingly clean.
But thanks to the clean walls, Ling Zhi soon found faint fluorescent traces on the wall next to the door. He got closer and looked carefully, and found three numbers arranged from top to bottom:
"-8"
"-2"
"-127"
Huh? Although Lexus has never played an escape room, there are digital clues, which are of course important clues.
But... is there any relationship between these three numbers? And why are they negative?
Furthermore, the 4-digit password lock only has 3 numbers. Is there another one that I haven’t discovered yet?
Lexus looked around the hall again, but saw no similar traces of fluorescence.
"Forget it, we can only analyze these three numbers first."
As Ling Zhi thought about it, he called Zhao Shiyan over and asked her to help him come up with ideas. "-8, -2, -127. Uh, that's weird. I don't understand the relationship between these three numbers at all."
Zhao Shiyan was a little confused and tried to suggest:
"Is it the single digit of each number?"
Ling Zhi shook his head silently and said:
"Probably not. Otherwise, the negative sign would be meaningless. But you can give it a try. You just need to try a few more times."
After Zhao Shiyan heard this, he nodded and chose 8, 2, and 7 in order. The last one was a little hesitant.
"If you don't know the fourth number, just fill in 0."
Ling Zhi suggested. Zhao Shiyan chose 0 as the last one, and then...nothing happened.
Surely it's not the right choice?
"By the way, can't we try it one by one from beginning to end? Even if we don't know the clues?"
"Try them one by one? Oh, you mean from 0000 to 9999."
"right."
Violent solution is not impossible, but each person has 10 choices, 4 digits, and if they are arranged and combined, there are 10,000 choices. Doesn't this make your hands swollen?
"It's too troublesome to solve it through violence. However, I don't have any ideas for the time being. Can you try it for me? Maybe the first few will solve it?"
"okay!"
Zhao Shiyan began to try diligently. Ling Zhi looked at the three numbers on the wall, thoughtfully.
After a while, Zhao Shiyan suddenly said "Ah", and Ling Zhi hurriedly asked:
"What's wrong? Shi Yan?"
Zhao Shiyan turned around awkwardly and said to Ling Zhi:
"Well, come and take a look, Ling Zhi."
Ling Zhi looked at the password lock and saw that the electronic screen displaying the password no longer displayed numbers, but was replaced by a few small characters:
"Lock screen for 10 minutes"
Ling Zhi suddenly had a black line coming out.
It's not fun, it's not fun at all!
What a joke!
When I get out, I will definitely let out a bad breath!
Ling Zhi said to Zhao Shiyan:
"It seems that brute force solutions are no longer possible. We still have to use our brains."
"Yeah, Lingzhi, do you have any ideas?"
"Well... I did find something, but... it doesn't follow the rules."
"Oh? What is it? Come and hear it."
"It's actually very simple. People who study mathematics should be very sensitive to these three numbers."
"8 is 2 raised to the third power."
"2 is 2 raised to the power of 1."
"And 127...Although 127 is not a multiple of 2, 128, which is similar to it, is 2 raised to the seventh power."
Zhao Shiyan's eyes suddenly lit up and he praised:
"Isn't this a rule? Lingzhi, if you can think of this, I think you are very close to the answer!"
"I also think there might be something to do with it, but even if I enter 3, 1, and 7, what about the fourth digit? Is it possible that it's still 0?"
"It's possible! And 127 is not a multiple of 2, so it might be 2 raised to the power 7 and needs to be subtracted by 1 in the end. In this way, the fourth number might be -1, and 1 is 2 raised to the power 0, of course 0
possible."
Lexus suddenly became excited.
"It makes sense, as expected of you!"
The two waited anxiously for 10 minutes. Although there was no watch and the mobile phone was taken away, after waiting for about the same time, Lexus must have passed 10 minutes, so they tried 3, 1, 7, 0 themselves.
Nothing happened. I pushed and pulled the door but it wouldn't open.
