I am a super cop

Chapter 199 He is here

琳达看了一下顾晨拿出的纸条，上面的数字清晰的写着：7、8、9、10、11。

Thinking back about the relevant passwords at home, the number arrangement that Gu Chen mentioned did not appear.

"Officer, this is not a password at home."

"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 sorting of numbers given by Gu Chen, but Gu Chen looked very serious.

"Gu Chen, let me just say that the numbers are just written casually. They don't have much meaning. You don't have to think too complicatedly about the problem."

Officer Wang's tense nerves just now have been relieved...

I am most afraid of being slapped in the face on the spot, but now it seems that that is the case.

"That's good." Gu Chen breathed a sigh of relief, "It's not the best password, so I don't have to guess about it."

"Junior Brother Gu, do you think that the numbers are related to the desk calendar?" Lu Weiwei saw Gu Chen repeating calculations early this morning, but he was deleting, deleting, and modifying, and knew that Gu Chen had doubts about this.

The negative answer given by Linda just now helped Gu Chen eliminate most of his doubts.

"That's right, I think the numbers on the desk calendar have something to do with the hint left by Mr. James." Gu Chen walked to the center of the living room, faced Linda and said:
"I checked Mr. James's relevant academic background. He is a top student at the University of England. He is also a relatively cautious person in the business field. There is no reason to leave some serial numbers on the desk calendar for no reason."

"Brother, does this James want to use numbers to associate with the contents on the desk calendar?"

Wei Junzhi, who had always been a passerby, suddenly thought of something according to Gu Chen's prompt.

"You're right." Gu Chen put the desk calendar that he took away last night from his bag, put it back on the table, and took it out from the evidence collection bag: "Everyone, look at these numbers."

Everyone gathered around, not knowing why.

"I think these numbers are probably left by Mr. James before he was kidnapped." Looking up at Police Officer Wang and Lu Weiwei, Gu Chen continued: "We all know several simple digital passwords, one of which is letters replace."

"Alphabet replacement?" Linda asked suspiciously, "What... what does this mean?"

"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 uttered Gu Chen's thoughts, and everyone was stunned.

In fact, Wei Junzhi didn't know what was going on with him. Following Gu Chen's train of thought, he could easily tell some of the knowledge he knew before combined with the situation on the spot.

"That's right, Wei Junzhi is right." Gu Chen nodded, expressing his agreement with Wei Junzhi.

Officer Wang pursed his lips and said, "What a 1A2B, is this the answer?"

Gu Chen shook his head: "It would be great if it could be this simple. Combined with the calendar, I can 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 for a while.

"Junior Brother Gu, what's the matter with the calendar password?" Lu Weiwei asked.

"I know this." Officer Wang, who has been dabbling in passwords, said involuntarily: "There are seven days in a week, and the corresponding English words are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday. 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, Police Officer Wang continued to point to the calendar on the table and said:

"There are 4 lines on the calendar table, for example, M2 represents Monday in the first line, and then find out the corresponding date, which is used to encrypt the known month, and then use 1 letters represented by 26 to 26 numbers to perform corresponding conversion, you can get the password expressed in letters."

"Senior Brother Wang is very good." Gu Chen also agreed immediately.

Lu Weiwei let out an "ah" and said, "What you said is very good, but after all, I don't quite understand it."

"If you can understand it, then it's not you, Lu Weiwei." Officer Wang said quite proudly, "The letter replacement explained by Wei Junzhi just now is the simplest password, and the calendar password I explained will be correspondingly complicated."

"Yes, Senior Brother Wang is right." Gu Chen wrote down the two types of passwords just now on the note: "We just talked about letter replacement 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."

The more Lu Weiwei listened, the more confused she became, she said in a daze, "What the hell is this mobile phone password and keyboard password? These password enthusiast clubs really love to toss about."

Gu Chen smiled and said: "It's actually 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."

"The keyboard password is a way of encrypting using letters arranged in sequence on typewriters, mobile phone keyboards, computer keypads, and telephone keyboards as password tables."

"Gu Chen is right. These are several simple digital passwords." Police Officer Wang also had the right to speak: "But if it is what I said before, such as Caesar password, fence password and other complex passwords, then it is even more difficult. It's hard to grasp."

"So the numbers that Gu Chen mentioned really correspond to the digital codes of the desk calendar?" Lu Weiwei was dumbfounded.

It seems that there are more colorful things in my cognitive worldview.

Gu Chen shook his head: "I have performed repeated calculations today, but I still haven't gotten an answer from these forms of codes, but I think that Mr. James is also a highly educated person, and he won't even know these basic codes. I think he must have used a simpler way to tell us directly who the person who kidnapped him is."

"Police officer." When Linda heard this, she hurried forward and said, "Please help me find a way. My husband James is fine."

Gu Chen looked at Tai Liben without saying a word, and used master-level reasonable reasoning to perform the final calculation after the elimination method,
It is not as complicated and cumbersome as before. Gu Chen eliminated all the complicated parts, and finally thought that the month has not been calculated yet, and his eyes lit up: "Could it be a derivative of the calendar password?"

"What do you mean?" Linda asked.

"That's the month, the month represented by the number." Gu Chen smashed his right fist into the heart of his left palm, and said excitedly, "I almost forgot about that."

"You mean... the number represents the month?" Lu Weiwei asked with her beautiful eyes.

"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 but blurt out.

"Totally correct." Gu Chen took advantage of the situation and took the lead in drawing out these English words, saying: "If the guess is correct, the answer Mr. James wants to tell us may be in a few English words."

In the hall, it suddenly became quiet...

Everyone held their breath, feeling as if they were going to be infinitely closer.

"Gu...Officer Gu." Linda swallowed, and said, "Then...then have you found 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 circled the first letter of each English word with a pen.

Gu Chen first circled the "J" from "July".

The "A" was then circled from "August".

From "September", "October" and "November", circle "S", "O" and "N" respectively.

Soon, at the bottom, Gu Chen reconstructed all the circled letters into a new word: Jason.

"It's... Jason?" Linda covered her mouth, took two steps back, and said in disbelief, "How could it be him? This...how is this possible?"

Gu Chen, Lu Weiwei, Police Officer Wang, and Wei Junzhi looked at each other, and it seemed that they could tell that the "Jason" Linda was talking about, obviously, she and James both knew each other.

"It's this person." Wei Junzhi suddenly pointed to the list given by Linda, and said in surprise: "Brother, look quickly, it's this person. There is a guy named 'Jason' in the list."

"Jason?" Officer Wang was taken aback for a moment, and then quickly asked, "Does your husband know this person very well?"

Linda nodded, feeling completely dazed.

She might have imagined it was someone else, but she didn't think it was Jason, which made it difficult for Linda to accept for a while. She leaned against the wall at a loss, her eyes staring blankly.

"Impossible, how is this possible?" Linda said anxiously to herself, with a slight trill in her speech, which caused everyone to look at each other.

Gu Chen frowned, stepped forward and asked, "Ms. Linda, are you okay? Who is this Jason? Can you tell me his details?"

After struggling for a while, Linda nodded and agreed after calming down:
"Jason, indeed, my husband James is a good friend, and they are also the co-founders of the trading company. My husband holds 60.00% of the shares in the company. He previously held 40.00%. Later, Jason sold his shares to other people. , his current shareholding is only 5.00%.”

The corners of Police Officer Wang's mouth immediately burst into 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 someone to follow him, I don't believe this guy can play 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 to start. This is all thanks to Junior Brother Gu."

"We just had good luck." Gu Chen was still quite modest, not greedy for credit: "If Mr. James just had a fluke mentality, or if he didn't give hope at all, then this string of numbers would be meaningless."

"Yes, Officer Gu." Linda also said gratefully: "This time I really trouble you, but I didn't expect that our family is good to Jason, and he would kidnap my husband. It seems unbelievable. I just hope It was a misunderstanding and my husband will do no harm."

Gu Chen just nodded and said: "We will solve the specific situation as soon as possible, and at the same time try our best to ensure the safety of Mr. James, so now you must tell me Jason's address."

Gu Chen has already taken out his notebook, ready to record the next useful information.

He was not sure about the meaning of these numbers before, and even failed to calculate many times in the early morning.

After all, if the direction is wrong, the investigation will fall into a bottomless pit.

Fortunately, the method was correct. Gu Chen didn't think in a complicated direction, but used the simplest relationship between numbers and desk calendars to find out this guy named Jason.

The next task is equally important, to 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 taken aback again, and looked up at Gu Chen.

"Who is it?" Gu Chen asked.

"It's my husband James' phone number," Linda said.

Officer Wang behind him immediately said: "You answer the phone first, hold him steady, and see what else he wants?"

"Okay...Okay!" Linda's relaxed nerves suddenly tensed up again, and she pressed the hands-free button.

At this time, on the phone, a man with voice processing 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 playing tricks on you. I really don't have any money. Can you let me see my husband first." Linda's reply attitude has been following Gu Chen's prompts.

Every time the man on the other side said a word, Gu Chen would immediately write a paragraph on the manuscript paper, and then asked Linda who answered the phone to read along.

After coming and going, the other party didn't seem to be able to take advantage of it, but Linda just didn't agree to let her talk to her husband.

"7 o'clock in the evening, how much money can you come up with?" the other party asked.

"Is 25 okay?" Linda directly cut the previous ransom amount in half.

The other party seemed a little irritated. Under the effect of the voice changer, he cursed: "Is your husband's life worth 25 yuan? Can you give 50 yuan?"

"Brother, I really can't do this. I don't have so much money in my hand, so I can only scrape together 25 yuan." After Linda finished speaking, she continued to wait for Gu Chen to read out another sentence: "If you Promise, I can send the money over now."

Another moment of silence...

Not long after, the other party finally compromised and said, "That's fine, you prepare the 25 first, and I will contact you again."

After speaking, the call was cut off.

"This kidnapper is an 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 kidnapper's familiarity with James, or it may be Jason's first time doing this, so he has little experience?" Police Officer Wang also analyzed objectively.

From everyone's point of view, the other party seemed to be inexperienced, and he didn't look like a habitual offender.

Linda stepped forward and asked, "Officer, what should I do? I'm going to raise money now, right?"

Police officer Wang said "hmm" and asked, "Can you make up 25 yuan?"

"That's no problem." Linda answered simply.

"Alright, I'll ask Wei Junzhi to raise money with you. Besides, Gu Chen, Lu Weiwei and I will go to Jason's house to see what's new with this guy."

"Thank you officer, thank you very much." Linda also bowed frequently.

Not long after, Officer Wang's cell phone rang.

After answering the phone, Comrade Wang said "hmm" several times, said thank you, and hung up the phone.

"The area where I called just now has been locked, it's near the old street." Officer Wang said.

When Gu Chen cooperated with Linda just now, he tried his best to hold the time.

And at this moment, Police Officer Wang has asked the technical department to lock the address of the mobile phone.

"Then let's go there now." Gu Chen said.

Ten minutes later...

According to the address provided by colleagues in the technical department, when Police Officer Wang, Lu Weiwei and Gu Chen rushed to the place where they had just called, there was no sign of anyone else around except for a few old men picking up trash.

"Jason must be still nearby. Everyone, take cover and don't be discovered by the other party." Officer Wang did not say anything according to the previous instructions, and explained to him one by one.

"Old Wang, don't worry, as long as Jason dares to show up, we won't 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, and sat down.

By the windows of the milk tea shop, you can see various situations at the intersection...

Playing with mobile phones, drinking milk tea, and observing every move on the roadside, everyone's mood remained high.

However, the time passed by every minute and every second, and at three o'clock in the afternoon, several people followed the store in turn, but still found no trace of Jason.

Lu Weiwei first set up a temporary WeChat group, and pulled Police Officer Wang, Gu Chen, Wei Junzhi and Linda into the group, and she also took the lead in sending messages in the group.

Lu Weiwei: "Old Wang, there is nothing abnormal here, what about yours? Is there anything wrong?"

Police Officer Wang: "I don't have either. Everything is normal. Jason's photo has been sent to you. Pay attention. By the way, where is Gu Chen?"

Gu Chen: "None."

Officer Wang: "..."

Lu Weiwei: "..."

Sure enough, it is the attribute of the first brother who saves words.

A long time passed, until seven o'clock in the evening, and the sky gradually dimmed. Police officer Wang drank milk tea and went to the toilet five times, but he didn't find Jason's presence, so he couldn't help but become alert to this guy.

At this time, Linda, who had been speechless all day, finally sent a message.

Linda: "Jason asked me to take the money and come to the Jasmine Milk Tea Shop to trade. I'm on my way now. Is any of you at the Jasmine Milk Tea Shop? Can someone come to meet me? I'm afraid."

Officer Wang: "Who is at the Jasmine Milk Tea Shop?"

Lu Weiwei: "I'm not here."

Wei Junzhi: "I'm not here either."

After a few seconds, Gu Chen sent a message: "He is here, sitting next to me."
