Linda looked at the note Gu Chen took out. The numbers on it were clearly written: 7, 8, 9, 10, 11.
After recalling the relevant passwords at home, the numerical arrangement that Gu Chen mentioned did not appear.
"Officer, this is not a home password."
"are you sure?"
"I...I'm sure it's definitely not the relevant password at home. I can't understand these numbers."
Linda didn't know what was so special about the numerical order given by Gu Chen, but Gu Chen looked very serious.
"Gu Chen, I just said that the numbers were written casually, and they don't have much meaning. You don't need to make the problem too complicated."
Officer Wang's nerves, which were tense just now, are now relieved...
I was most afraid of being slapped in the face on the spot, but now it seems that that’s all.
"That's good." Gu Chen breathed a sigh of relief and said with relief: "It's better not to have a password, so I don't have to guess in this aspect."
"Junior Brother Gu, do you think the numbers have something to do with the desk calendar?" Lu Weiwei saw Gu Chen repeatedly calculating and deleting and modifying things early this morning, and she also knew that Gu Chen had doubts in this regard.
The negative answer Linda gave just now helped Gu Chen eliminate most of his doubts.
"Yes, I think the numbers on the desk calendar are related to the hints left by Mr. James." Gu Chen walked to the center of the living room, faced Linda and said:
"I checked the relevant academic background of Mr. James. He is a top student at the University of England. He is also a cautious person in the business world. There is no reason to leave some serial numbers on the desk calendar for no reason."
"Brother, does James want to use numbers to correlate with the contents on the desk calendar?"
Wei Junzhi, who was standing aside and looked like a passerby, suddenly thought of something based on Gu Chen's prompts.
"You're right." Gu Chen took the desk calendar he took away last night from his bag, put it back on the table, and took it out from the evidence bag: "Everyone, take a look at these numbers."
Everyone gathered around, not knowing what to do.
"I think these numbers are most likely left behind by Mr. James before he was kidnapped." Looking up at Officer Wang and Lu Weiwei, Gu Chen continued: "We all know several simple numerical passwords, one of which is letters.
replace."
"Letter substitution?" Linda asked doubtfully: "What...what does this mean?"
"Senior Brother Gu means that this is the simplest password, that is, 1 represents a, 2 represents b, and so on, using numbers to encrypt English letters or Chinese pinyin."
Wei Junzhi, who was originally standing in the corner, once again expressed Gu Chen's thoughts, leaving everyone confused.
In fact, Wei Junzhi didn't know what was going on with him. Following Gu Chen's train of thought, he could easily combine some of the knowledge he knew before and combine it with the situation at the scene.
"Yes, Wei Junzhi is right." Gu Chen nodded, expressing his agreement with Wei Junzhi.
Officer Wang curled his lips and said: "What a 1a2b, is this the answer?"
Gu Chen shook his head: "It would be great if it could be that simple. Combined with the calendar, I can also think of a calendar password."
"Calendar password?" Lu Weiwei had never heard of this before, so when Gu Chen said it, it was difficult to follow Gu Chen's train of thought.
"Junior Brother Gu, what's going on with the calendar password?" Lu Weiwei asked.
"I know this." Officer Wang, who has always been involved in passwords, couldn't help but said: "There are seven days in a week, and the corresponding English words are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday, and we distinguish these
You can use m, t1, w, t2, f, s1, s2 to represent the seven days of the week."
Seeing Lu Weiwei's slightly dull look, Officer Wang continued to point to the calendar on the table and said:
"There are 4 rows in the calendar. For example, m2 represents Monday in the first row. Then find the corresponding date and the known month used to encrypt it, and then use 26 letters represented by 1 to 26 numbers to perform the corresponding
By converting it, you can get the password represented by letters."
"Senior Brother Wang said it very well." Gu Chen also agreed immediately.
Lu Weiwei said "Oh" and said, "What you said is very good, but after all, I don't quite understand it."
"If you want to understand, it's not you, Lu Weiwei." Officer Wang said proudly: "The letter substitution explained by Wei Junzhi just now is the simplest password, but the calendar password I explained will be correspondingly complicated."
"Yes, Senior Brother Wang is right." Gu Chen wrote down the two password categories on the note: "What we just talked about were letter substitution and calendar passwords. In fact, there are many similar passwords, all of which are password hobbies.
Among them are mobile phone passwords and keyboard passwords that are highly recommended by the Reader’s Club.”
The more Lu Weiwei listened, the more confused she became, and she said blankly: "What the hell are these mobile phone passwords and keyboard passwords? These password enthusiast clubs really love to mess around."
Gu Chen smiled and said: "Actually, it's very simple. The mobile phone password is encrypted using the mobile phone keyboard. For example, the pinyin 9 key, 94 represents z, that is, the last pinyin letter of the number 9 is z."
"Keyboard passwords are a way of encrypting using letters arranged in sequence from typewriters, mobile phone keyboards, computer keypads, telephone keyboards, etc. as a password table."
"Gu Chen is right, these are several simple digital passwords." Officer Wang also had the right to speak: "But if it is what I said before, such as Caesar cipher, fence cipher and other complex passwords, then it will be even more complicated.
It’s hard to master.”
"So these numbers that Gu Chen mentioned really correspond to the digital codes of the calendar?" Lu Weiwei said in shock.
It's as if there are more dazzling things in my cognitive worldview.
Gu Chen shook his head: "I have done repeated calculations today, but I have not gotten the answer from these password forms, but I think Mr. James is also a highly educated person after all, and he will not even know these basic passwords.
I think he must have used a simpler way to tell us directly who kidnapped him."
"Officer." When Linda heard this, she hurriedly stepped forward and said, "Please help me find a way. Nothing will happen to my husband James."
Gu Chen looked at Tai Liben without saying a word, using a master's level of reasonable reasoning to perform the final calculation after elimination.
It was not as complicated and cumbersome as before. Gu Chen eliminated all the complicated parts and finally thought that the month had not been calculated yet. His eyes suddenly lit up: "Is it a derivative of the calendar password?"
"What do you mean?" Linda asked.
"That's the month, the month represented by the number." Gu Chen punched his right fist into the palm of his left hand and said excitedly: "I almost forgot about this."
"You mean...the numbers represent months?" Lu Weiwei asked with her beautiful eyes widened.
"Let's try it."
Gu Chen took out the sticky note again and listed the English words from January to December in order: "If 1 corresponds to January, then 2 is February, and so on."
"So, the numbers 7, 8, 9, 10, and 11 you found correspond to July, August, September, October, and November?"
Lu Weiwei looked at the English written by Gu Chen and couldn't help blurting out.
"Absolutely correct." Gu Chen also took the opportunity to outline these English words and said, "If I guess correctly, the answer Mr. James wants to tell us may be among a few English words."
In the hall, it suddenly became quiet...
Everyone held their breath, feeling as if they were infinitely close.
"Gu... Officer Gu." Linda swallowed a mouthful of saliva and said, "Then... did you find any clues left by my husband?"
Gu Chen didn't speak, but stared at the English letters in front of him...
After a while, he reached out and drew the first letter of each English word with a pen circle.
Gu Chen first circled the "j" from "july".
Then he circled the "a" from "august."
Then from "september", "october" and "november", circle "s", "o" and "n" respectively.
Soon, at the bottom, Gu Chen reorganized all the circled letters into a new word: Jason.
"Is it... is it Jason?" Linda covered her mouth, took two steps back, and said in disbelief: "How could it be him? How... how could this be possible?"
Gu Chen, Lu Weiwei, Officer Wang and Wei Junzhi looked at each other in confusion, and they seemed to be able to tell that the "jason" in Linda's mouth clearly meant that she and James knew each other.
"It's this person." Wei Junzhi suddenly pointed to the list given by Linda and said in surprise: "Brother, look, it's this person. There is a guy named 'Jason' on the list."
"Jason?" Officer Wang was stunned for a moment, then quickly asked: "Is your husband familiar with this person?"
Linda nodded, feeling completely confused.
She might have imagined that it was someone else, but she didn't expect it to be Jason. This made it difficult for Linda to accept it for a while. She leaned against the wall at a loss, her eyes blankly blank.
"Impossible, how is this possible?" Linda said anxiously to herself, with a slight trembling in her voice, which made everyone look at each other.
Gu Chen frowned and stepped forward and asked: "Ms. Linda, are you okay? Who is this Jason? Can you tell me his details?"
Linda, who had been struggling for a while, finally nodded and agreed after calming down:
"Jason is indeed a good friend of my husband James, and they are also co-founders of a trading company. My husband holds 60% of the company's shares. He previously held 40%. Later, Jason transferred his
The shares were sold to other people, and he currently only holds 5% of the shares."
Officer Wang's mouth immediately lit up with joy, and he hurriedly said: "Now that we know who it is, it's easy to handle. As long as we find Jason and send people to keep an eye on him, I don't believe this guy can do new tricks?
"
Lu Weiwei also said: "This Jason must not be let go. Fortunately, Mr. James left this series of numbers before he was kidnapped. Otherwise, we really have no way of starting. This is all thanks to Junior Brother Gu."
"We just got lucky." Gu Chen was still quite modest and did not want to take credit: "If Mr. James just has a lucky mentality, or has no hope at all, then these numbers will be meaningless."
"Yes, Officer Gu." Linda also said gratefully: "This time I really trouble you, but I didn't expect that our family has been very good to Jason, but he would kidnap my husband. This seems a bit unbelievable. I just hope
This was a misunderstanding and my husband will not be harmed."
Gu Chen just nodded and said: "We will solve the specific situation as soon as possible and try to ensure the safety of Mr. James. Now you must tell me Jason's address."
Gu Chen had already taken out his notebook, preparing to record the next useful information.
He was not sure about the meaning of these numbers before, and even calculated them many times in the early morning but failed.
After all, if the direction is wrong, the investigation will fall into a bottomless pit.
Fortunately, the method was correct. Gu Chen did not think in a complicated direction, but used the simplest correlation between numbers and calendars to find this guy named Jason.
The next task is equally important, find Jason's residence and rescue the trapped James.
Just as everyone was discussing how to rescue Mr. James, Linda's cell phone rang.
The moment she picked up the phone, Linda was stunned again and looked up at Gu Chen.
"Who is it?" Gu Chen asked.
"That's my husband James's phone number," Linda said.
Officer Wang behind him immediately said: "You answer the phone first, stabilize him, and see what else he wants?"
"Okay...ok!" Linda's relaxed nerves suddenly became tense again and she pressed the hands-free button.
At this time, on the phone, a man whose voice had been processed said: "What do you think about the money I want?"
"I...I don't have that much money, really." Linda said.
"You fool me?"
"No, I'm not kidding you. I really have no money. Can you let me see my husband first?" Linda's response was based on Gu Chen's prompts.
Every time the man on the other side said something, Gu Chen would immediately write a paragraph on the manuscript paper, and then ask Linda who answered the phone to read it after him.
After going back and forth, it seemed that the other party could not take any advantage, but he did not agree to let Linda talk to her husband.
"How much money can you take out at 7 o'clock in the evening?" the other party asked.
"Is 250,000 okay?" Linda directly cut the previous ransom amount in half.
The other party seemed a little irritated. Under the influence of the voice changer, he cursed: "Is your husband's life worth only 250,000? Can you afford 500,000?"
"Brother, we really can't do this. I don't have that much money, so I can only scrape together 250,000 yuan." After Linda finished speaking, she continued to wait for Gu Chen to read out another paragraph she had written: "
If you agree, I can send the money over now."
There was another moment of silence...
Not long after, the other party finally compromised and said: "Okay, you prepare the 250,000 first, and I will contact you again."
After saying that, the call was cut off.
"This kidnapper is so amateur!" Lu Weiwei couldn't help complaining and murmured: "This is the first time I have met such a stupid kidnapper."
"This may have something to do with the fact that the kidnapper is familiar with James. It may also be the first time Jason has done this, so he is a little inexperienced, right?" Officer Wang also analyzed objectively.
In everyone's opinion, the other party does seem to be inexperienced, and he doesn't look like a habitual offender.
Linda stepped forward and asked: "Officer, what should I do? Is it right for me to raise money now?"
Officer Wang said "hmm" and asked, "Can we get 250,000 together?"
"That's no problem." Linda answered simply.
"Okay, I'll ask Wei Junzhi to raise money with you. In addition, Gu Chen, Lu Weiwei, I, and we will go near Jason's house to see what new news this guy has."
"Thank you, officer, thank you very much." Linda also bowed frequently.
Not long after, Officer Wang's cell phone rang.
After answering the call, Comrade Lao Wang said "hmm" several times, said thank you and hung up the phone.
"We have locked the area where we just made the call, which is near the old street." Officer Wang said.
Just now, when Gu Chen and Linda were cooperating, they tried their best to save time.
At this moment, Officer Wang had already asked the technical department to lock the phone call address.
"Then let's go there now." Gu Chen said.
Ten minutes later...
According to the address provided by colleagues in the technical department, when Officer Wang, Lu Weiwei and Gu Chen arrived at the place where the call was just made, except for a few old men picking up garbage, there was no trace of anyone else around.
"Jason must still be nearby. Please take cover and avoid being discovered by the other party." Officer Wang followed the previous instructions and explained to Nan one after another.
"Lao Wang, don't worry, as long as Jason dares to show up, we will not let him go." Lu Weiwei was also quite excited about the arrest operation.
After a brief exchange, the few people dispersed and went to several drink shops with floor-to-ceiling windows at the intersection, where they sat down.
From several windows in the milk tea shop, you can see various situations at the intersection...
Playing with their mobile phones, drinking milk tea, and observing every move on the roadside, everyone's mood remained high.
However, time passed by, and at three o'clock in the afternoon, several people alternately followed the store, but still found no trace of Jason.
Lu Weiwei first established a temporary WeChat group and brought Officer Wang, Gu Chen, Wei Junzhi and Linda into the group. She also took the lead in sending messages to the group.
Lu Weiwei: "Old Wang, there is nothing abnormal here. What about your place? Is there anything wrong?"
Officer Wang: "I don't have this either. Everything is normal. Jason's photo has been sent to you. Please pay attention. By the way, where are you, Gu Chen?"
Gu Chen: "No."
Officer Wang: "..."
Lu Weiwei: "..."
As expected, he has the attribute of saving words.
A long time passed, until seven o'clock in the evening, the sky gradually darkened. Officer Wang drank milk tea and ran to the toilet five times, but did not find Jason anywhere, so he couldn't help but become wary of this guy.
At this time, Linda, who had been speechless all day, finally sent a message.
Linda: "Jason asked me to bring money to the Jasmine Milk Tea Shop for business. I'm on my way now. Are any of you at the Jasmine Milk Tea Shop? Can someone pick me up? I'm scared."
Police Officer Wang: "Who is at the Jasmine Milk Tea Shop?"
Lu Weiwei: "I'm not here."
Wei Junzhi: "I'm not here either, I'm staying with Linda."
After a few seconds, Gu Chen sent a message: "He's here and he's sitting next to me."
