After all, this is the most meaningful conjecture. If this is not the standard answer, then what is the standard answer?
Ling Zhi didn't dare to try again, fearing that if he tried too many times, the lock screen mechanism would be triggered. He stood up slowly, thoughtfully.
"Um, isn't it?"
Zhao Shiyan was a little unwilling and immediately stepped forward to try again. Ling Zhi thought about it and didn't stop her. At worst, he would have to wait another 10 minutes.
Zhao Shiyan put 0 in a different position, or tried again in reverse order, but none of them succeeded. Soon, the 10 minutes for the second lock screen came.
"Oh, this broken lock is really annoying!"
Zhao Shiyan said angrily. After getting up, he couldn't help but kick the door hard twice.
Well, this girl is really stubborn.
But don't call her stubborn, Ling Zhi himself was in a mess. Ling Zhi suggested searching for clues in the house carefully to see if there would be any new discoveries.
So their figures were left on the wall, in the food pile, inside the toilet seat, and under the bed. However, they still couldn't find the fourth fluorescent number.
So they began a long period of speculation.
Two computers, the last number is 2?
Pile of food. Yes, count how many bottles of water there are and how many compressed biscuits there are.
There are 4 barrels of bottled water and many compressed biscuits, but they are all distributed in 6 boxes.
The two again added 4 and 6 to the decoding army, and tried over and over again, without exception, without success.
The two also thought about whether to add up the three digits of 127, which would be 10. If 10 was split into 3 and 4 digits, then the password would most likely be 3, 1, 1, 0. However, they did not succeed.
.
In the end, the two of them sat on the bed in Ling Zhi's room, leaning against the wall, helplessly thinking about all the possibilities.
They have been trying for a long time, splitting numbers, splitting digits, adding, subtracting, multiplying and dividing, everything. However, there is no movement at all from that damn door.
The two of them have gone crazy, and they are not going to let go of any clues related to numbers.
Lexus always felt that something was missing. Yes, in all the attempts just now, the negative sign was not used. However, the number that can be selected is only 0-9, and negative numbers cannot be selected. What is the meaning of the existence of the negative sign?
?
Ling Zhi had no idea for a while.
The computer in front of me is still on, and the chat box in front of me has not changed much.
"Lingzhi, how about we count how many buttons there are on the keyboard."
Ling Zhi suddenly couldn't laugh or cry:
"Then forget it, there's no need to go to this extent."
"Oh, yes."
Zhao Shiyan pouted, feeling very depressed.
Although he thinks this proposal is ridiculous, Ling Zhi also understands it very well. After all, when people are desperate, they want to grab any life-saving straw.
But what about the keyboard?
Ling Zhi looked at the computer in front of him, and his heart moved. He sat in front of the table, typed on the keyboard with his hand and said:
"We have given up. How to get out? Please tell us the password."
After all, it's an escape room. If I can't escape, I'll just give up.
Of course, this computer does not have an input method, so Lexus sent it in Pinyin.
After sending it, there was no response for a while.
After Zhao Shiyan saw Ling Zhi's actions, he also went to his room and sent it again, but of course there was no response.
It shouldn't be.
Since it's an escape room, there must be an emergency mechanism to prevent escape. Could it be that if we can't escape, you will lock us up here for the rest of our lives?
That's obviously impossible.
Although there is a bathroom here, as well as food and drink, there will always be a time when they finish eating. If no one comes to replenish the food, won't the two of them starve to death?
There were too many questions to answer. But fortunately, sending messages on the computer now should not have any bad effects, so he started an awkward chat with the imaginary person:
"Hello, how can we let us out?"
"Hello, let's make some conditions. We are willing to negotiate on any conditions."
"How much does it cost? I have my mobile phone with you. I will tell you the unlock code and you can withdraw the money yourself."
Lexus sent a lot of messages on his own, of course, all in Pinyin. After a long time, Lexus felt that the other party might look impatient, so he even used English:
"areyoukiddingme?"
However, no matter how hard he tried, the other party refused to spare a word.
Ling Zhi leaned back on the chair helplessly, his eyebrows tingling in pain. He stood up and walked towards Zhao Shiyan's room to see what she was doing.
Zhao Shiyan was also imitating Ling Zhi and chatting with the other party. Ling Zhi looked at the pinyin sent by Zhao Shiyan and couldn't help but feel a little heavy.
"Hello, you can let Ling Zhi go out, let me stay, and let him come back with the ransom. Then you will feel relieved..."
Words like this.
Ling Zhi felt his eyes were a little moist. He quickly put away his emotions, wiped his eyes, silently pressed Zhao Shiyan's shoulder and said:
"Forget it, it's probably useless. Let's rest for a while."
Ling Zhi sat on the edge of the bed behind him, thinking about the meaning of the three numbers on the wall.
"negative number."
"A positive number."
“What is the difference between negative numbers and positive numbers?”
Ling Zhi kept thinking in his mind.
"Oh, Lexus, I'm so annoyed. It would be great if this computer could access the Internet. I could also search for any similar cases."
"Uh, Ling Zhi, what's wrong with you? Why don't you speak?"
Zhao Shiyan waved his hand in front of Ling Zhi.
Ling Zhi's eyes suddenly lit up, he stood up suddenly, hugged Zhao Shiyan and spun around and said:
"Awesome! Shi Yan! You are simply a genius!"
Forehead.
Zhao Shiyan was a little confused.
Ling Zhi just stood up suddenly, startling her.
He picked her up again, and she felt like her ears were about to turn red with embarrassment.
But she was not disgusted. Seeing Ling Zhi like this, she knew he must have thought of something. After Ling Zhi put her down, she asked without hesitation:
"Ling Zhi, you are so excited, have you thought of any clues?"
"Of course, thanks to you, otherwise I wouldn't have discovered the meaning of the negative sign."
"You are really a genius girl!"
Zhao Shiyan was a little embarrassed. But she knew that this was not the point, so she immediately focused on the clues:
"Then tell me, what did you think of?"
Ling Zhi sat on the chair and said to Zhao Shiyan:
"It's actually very simple. I have been thinking about the difference between negative numbers and positive numbers for a long time, but I have no clue. Just now you mentioned computers, and I just thought that there is a difference between negative numbers and positive numbers in the computer binary encoding process.
.”
"Ah? What's the difference?"
Although Ling Zhi wanted to go to the door and try it the moment he guessed the clue, he calmed down at this time. After all, he didn't know what was going on outside the door, so he might as well think about it clearly before opening the door.
Ling Zhi used the chat box in front of him to explain to Zhao Shiyan:
"You see, 8 is represented by 00001000 in binary, which is 2 raised to the third power."
"And -8 is the binary representation of positive 8 with the complement of 11110111 followed by 1, which is the complement of 11111000."
"And -2 is 11111110."
"-127 is 10000001."
Seeing this, Zhao Shiyan suddenly realized. He grabbed Ling Zhi's arm and shook it excitedly:
"Haha! I understand. In this case, we just count the number of sticks, right?"
Um, wooden sticks? That's right. Judging from the binary representation, there are several wooden sticks in it, so it's probably the password.
Seeing that Zhao Shiyan was about to run out, Ling Zhi quickly stopped her and added:
"Hey, Shi Yan, don't be impatient for now. Let's think it through and then decide."
Zhao Shiyan was a little confused and asked:
"Oh? Is there anything else that needs to be clarified?"
Lexus explained:
"There are two things. We will think about it carefully before we open the lock."
"1. The first three digits are probably 5, 7, and 2. The fourth digit is still unclear, but let's calculate it based on 0 first."
Zhao Shiyan nodded and agreed. Ling Zhi continued:
"2. What will we do after we get out?"
"What should we do? Yes, if there is someone outside, we have to find someone skilled to defend ourselves."
After that, she started looking around the house. Of course, there was nothing else in the house except the computer, so she planned to run to the living room to see if there was anything she could use.
Ling Zhi didn't know whether to laugh or cry, so he followed her out and said:
"We have searched the hall many times, but we haven't seen anyone taking advantage of it. How about getting a chair? If there is an unexpected situation, hitting it with a chair may still have some effect."
Zhao Shiyan's eyes lit up, he ran back to his room and moved the chair out.
"Well, I'll try 5720. If it succeeds, I'll open the door a little and take a look at what's going on outside. If there are too many people, I'll open the door right away and you can throw the chair out, okay?"
Zhao Shiyan nodded firmly.
So, Ling Zhi squatted on the ground and opened the lock, and Zhao Shiyan was carrying a chair behind him. This style of painting... was a bit uncoordinated.
"drop……"
The combination lock rang.
Ling Zhi felt happy. The moment he opened the door, thoughts flashed through his mind:
"I didn't expect it to be related to binary. I should have thought of it earlier."
"Although the previous game theory originated from economics, it has been closely integrated with computers in recent years, forming a discipline called game learning."
"Game theory, binary system, the person who designed this secret room is a computer major? Who could he be?"
"Except for my roommates and lab classmates, I don't know anyone else who studies computer science, right?"
"Is it Bai Ming and the tattooed man? Neither of them look like people who understand binary. Who did I offend?"
Ling Zhi had more and more doubts in his heart, but as the door was about to open, he had to suppress his doubts. No matter what, he should escape from here first.
Ling Zhi opened a crack in the door and looked outside. There was no one in sight, but he saw a Chinese table.
"Is there a billiards room outside? But the environment doesn't look like a billiards shot. Is it in someone's home? This possibility cannot be ruled out."
Ling Zhi boldly opened the door a little wider and stuck his head out.
There are two sofa seats next to the ball table. There is a person sitting on one of the seats, his head lowered, and there is no movement.
"Is there only one person? That's easy to solve. You don't need a chair. It's impossible for two people to work together. But, why does that person's figure look familiar?"
Ling Zhi breathed a sigh of relief, and was about to tell Zhao Shiyan that there was only one person and that he should go out to see the situation first, when the man raised his head.
Ling Zhi glanced at the man's face, suddenly retracted his head and slammed the door, gasping for air, sweating on his body, and fell to the ground, his eyes filled with disbelief.
If we rule out the possibility that he was mistaken, the person on the sofa seat is the seven-time British Billiards World Championship winner:
