Linda looked at the note that Gu Chen took out, and the numbers on it were clearly written: 7, 8, 9, 10, 11.

Thinking back to the relevant passwords at home, there was no arrangement of the numbers that Gu Chen said.

"Officer, it's not some home password. ”

"Are you sure?"

"I ...... I'm sure, it's definitely not the relevant password at home, and I can't make out the numbers. ”

Linda didn't know what was so special about the order of numbers given by Gu Chen, but Gu Chen looked very serious.

"Gu Chen, I just said that the numbers were written casually, it doesn't mean much, and you don't have to think too complicated about the problem. ”

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

I'm most afraid of being slapped in the face on the spot, but now it seems that it's just like that.

"That's good. Gu Chen breathed a sigh of relief and said with relief: "It's not the best password, so I don't have to guess in this regard." ”

"Senior Brother Gu, do you think that numbers have something to do with the desk calendar?" Lu Weiwei saw Gu Chen repeatedly calculating early this morning, but he was deleting, deleting, modifying, and modifying, and she also knew that Gu Chen had doubts in this regard.

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

"Yes, I think the numbers on the desk calendar have something to do with the hints that Mr. James left behind. Gu Chen walked to the center of the living room, faced Linda and said:

"I have checked the relevant academic background of Mr. James, he is a top student at the University of England, and he is also a more cautious person in the business field, there is no reason to leave some tandem numbers in the desk calendar for no reason. ”

"Senior brother, will this James want to use numbers to associate with the content on the desk calendar?"

Wei Junzhi, who had been standing on the side and had been a passerby, suddenly thought of something according to Gu Chen's prompt.

"You're right. Gu Chen put the desk calendar book he had taken away last night back on the table from his bag, and took it out of the evidence bag: "Let's take a look at these numbers." ”

Everyone gathered around, one by one, not knowing why.

"I think it's very likely that these numbers were 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 numeric passwords, one of which is letter replacement. ”

"Letter replacement?" Linda wondered, "this ...... What does this mean?"

What Senior Brother Gu means is that this is the simplest password, that is, 1 represents A, 2 represents B, and so on, using numbers to encrypt English letters or Hanyu Pinyin. ”

Wei Junzhi, who was originally standing in the corner, once again said Gu Chen's thoughts, and everyone was confused.

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 scene.

"That's right, Wei Junzhi is right. Gu Chen nodded, expressing his approval of Wei Junzhi.

Officer Wang pouted and said, "What a 1A2B, is this the answer?"

Gu Chen shook his head: "It would be nice if it could be so 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 keep up with Gu Chen's train of thought for a while.

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

"I know that. Officer Wang, who has always been involved in passwords, also couldn't help but say: "There are seven days in a week, and the corresponding English words are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday, and we can use M, T1, W, T2, F, S1, and S2 to represent the seven days of the week." ”

Looking at Lu Weiwei's slightly sluggish appearance, Officer Wang continued to point to the desk calendar on the table and said:

"There are 4 rows on the calendar, for example, M2 represents the Monday of the first row, and then find out the corresponding date, which is known to encrypt the month, and then use 1~26 numbers to represent 26 letters, and carry out the corresponding conversion, you can get the password represented by letters. ”

"Senior Brother Wang said it very well. Gu Chen also agreed at the first time.

Lu Weiwei sighed and said, "What you said is very good, but I don't understand it after all." ”

"If you can understand, it's not you, Lu Weiwei. Officer Wang was also quite proud: "The letter replacement that Wei Junzhi explained 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 password categories on the note: "What we just talked about is letter replacement and calendar passwords, in fact, there are many similar passwords, all of which are recommended by the crypto enthusiast club, including mobile phone passwords and keyboard passwords. ”

The more Lu Weiwei listened, the more confused she became, and she was stunned: "What the hell is this mobile phone password and keyboard password? “

Gu Chen smiled and said: "Actually, it's very simple, the mobile phone password is encrypted by using the mobile phone keyboard, such as 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 to encrypt the letters in the order of typewriters, mobile phone keyboards, computer keypads, telephone keypads, etc. ”

"Gu Chen is right, these are several simple numeric passwords. Officer Wang also had the right to speak: "But if it is what I said before, complex passwords such as Caesar passwords, fence passwords, etc., it will be even more difficult to master." ”

"So these numbers that Gu Chen said are really the numerical passwords corresponding to the desk calendar?" Lu Weiwei was dumbfounded.

It's as if there are more colorful things in my cognitive worldview.

Gu Chen shook his head: "I have done repeated calculations today, and I have not gotten answers from these forms of passwords, but I think Mr. James is also a highly educated person, and he will not even know these basic passwords, I think he must have used a simpler way to directly tell us who the person who kidnapped him was." ”

"Officer. When Linda heard this, she hurriedly stepped forward and said, "Please help me figure it out, my husband James can't be fine." ”

Gu Chen looked at the table without saying a word, and used master-level reasoning to perform the final calculation after the elimination method,

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, and suddenly his eyes lit up: "Could it be a derivative of the calendar password?"

"What do you mean?" asked Linda.

"That's the month, the month that the numbers represent. Gu Chen smashed his right fist into the palm of his left palm, and said excitedly: "I almost forgot this." ”

"You mean...... What does the number represent the month?" asked Lu Weiwei with a beautiful look in her eyes.

"Give it a try. ”

Gu Chen took out the sticky notes again and listed the English words from January to December in turn: "If 1 corresponds to January, then 2 is February, and so on." ”

"So, the numbers you found 7, 8, 9, 10, 11 correspond to July, August, September, October, and November?"

Lu Weiwei looked at Gu Chen's English and couldn't help blurting out.

"Exactly. Gu Chen also took the opportunity to outline these English words first, and said: "If you guess correctly, the answer that Mr. James wants to tell us first may be in a few English words." ”

The hall suddenly fell silent......

Everyone held their breath and felt like they were going to get infinitely closer.

"Gu ...... Officer Gu. Linda swallowed a mouthful of saliva and said, "That...... 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 moment, he reached out and drew the first letter of each English word in a circle with a pen.

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

This was followed by a circled "A" from "August".

From "September", "October" and "November", the "S", "O" and "N" are circled, respectively.

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

"Yes...... Is it Jason?" Linda covered her mouth and took two steps back, incredulous, "How could it be him......?" How is this possible?"

Gu Chen, Lu Weiwei, Officer Wang and Wei Junzhi, the four of them looked at each other, and they seemed to be able to see that the "Jason" in Linda's mouth was obviously known to both her and James.

"It's this person. Wei Junzhi suddenly pointed to the list given by Linda, and exclaimed: "Senior brother, look, it's this person, there is a guy named 'Jason' in the list." ”

"Jason?" Officer Wang was stunned for a moment, and then quickly asked, "Your husband is very familiar with this person?"

Linda nodded, feeling confused.

She may have imagined that it would be someone else, but she didn't expect it to be Jason, which made Linda unacceptable for a while, and the whole person leaned against the wall at a loss, her eyes stunned.

"Impossible, how is this possible?" Linda said to herself anxiously, with a slight trilling voice in her voice, causing 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?"

Linda, who had been entangled for a while, nodded and agreed after calming down:

"Jason, it's true that I'm good friends with my husband James, and they're also co-founders of the trading company, and my husband owns 60 percent of the company, he used to have 40 percent, and then Jason sold his own shares to somebody else, and he's only 5 percent of the shares now. ”

The corners of Officer Wang's mouth immediately bloomed, and he hurriedly said: "Since you know who it is, it's easy to do, as long as you find Jason and send someone to target him, I don't believe that this guy can play new tricks?"

Lu Weiwei also said: "This Jason must not be let go, fortunately, before Mr. James was kidnapped, we left this series of numbers, otherwise we really have no way to start, which is a lot of harm to Senior Brother Gu." ”

"We just had good luck. Gu Chen was still quite modest and did not be greedy: "If Mr. James just has a fluke mentality, or there is no hope at all, then this string of numbers will be meaningless." ”

"Yes, Officer Gu. Linda was also grateful: "It's really troublesome for you this time, but I didn't expect that one of our family was good to Jason, and he would kidnap my husband, which seems a little unbelievable, I just hope this is a misunderstanding, and my husband won't be harmed." ”

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

Gu Chen had already taken out his notebook, ready to record the useful information that followed.

He wasn't sure what the numbers meant, and even failed to do it 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 did not think in a complicated direction, but used the simplest correlation between numbers and the station to find out this guy named Jason.

The next mission 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 stunned again and looked up at Gu Chen.

"Who is it?" asked Gu Chen.

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

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

"Good...... Okay!" Linda's flaccid nerves suddenly tensed up again and pressed the hands-free button.

At this time, on the phone, a man with voice processing said, "How do you think about the money I want?"

"I ...... I don't have that much money, really. Linda said.

"You're kidding me?"

"No, it's not to fool 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 ask Linda, who answered the phone, to read it along.

After going back and forth, the other party didn't seem to take any advantage, but he just didn't promise Linda to let her talk to her husband.

"How much money can you come up with at 7 p.m.?" asked.

"Is 250,000 okay?" Linda directly cut the previous ransom amount in half.

The other party seemed to be a little enraged, and under the effect of the voice changer, he scolded and scolded: "Is your husband's life worth 250,000? Can you take out 500,000?"

"Big brother, I really can't do this, I don't have so much money in my hand, I can only make up 250,000 yuan. After Linda finished speaking, she continued to wait for Gu Chen to read out the other paragraph that she had written: "If you agree, I can send the money over now." ”

There was silence again......

It didn't take long for the other party to finally compromise: "Okay, you prepare the two hundred and fifty thousand first, and I will contact you again." ”

After that, the phone was cut off.

"This kidnapper is very amateurish!" Lu Weiwei couldn't help but complain and muttered, "It's the first time I've met such a stupid kidnapper." ”

"This may have something to do with the kidnappers' familiarity with James, or it may be Jason's first time doing this, so he is a little inexperienced, right?" Officer Wang also objectively analyzed.

In everyone's opinion, the other party seems to be inexperienced, and it can be seen that he does not look like a repeat offender.

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

Officer Wang let out an "um" and asked, "Can you make up twenty-five?"

"That's fine. Linda replied crisply.

"That's okay, I'll let Wei Junzhi go with you to raise money, and in addition, I'll go to the vicinity of Jason's house with Gu Chen and Lu Weiwei, and we'll go to the vicinity of Jason's house to see what new things this guy has done. ”

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

It wasn't long before Officer Wang's cell phone rang.

After connecting the phone, Comrade Wang said "uh-huh" several times, said thank you and hung up the phone.

"The area where I just called has been locked, just near Lao Cai. Officer Wang said.

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

At this time, Officer Wang has already asked the technical department to lock the mobile phone call address.

"Then we'll go now. Gu Chen said.

Ten minutes later......

According to the address provided by the colleagues in the technical department, when Officer Wang, Lu Weiwei and Gu Chen rushed to the location of the call just now, except for a few old men who picked up garbage, there was no trace of anyone else around.

"Jason must still be nearby, everyone pay attention to find cover and don't be discovered by the other party. Officer Wang didn't say anything according to the previous instructions, and explained to him in turn.

"Lao Wang, don't worry, as long as Jason dares to appear, we will not let him go. Lu Weiwei is also quite excited about the arrest operation.

After a short exchange, they dispersed and went to several drink shops with floor-to-ceiling windows at the intersection and sat down.

There are several windows in the bubble tea shop, and you can see various situations at the intersection......

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

However, time passed minute by minute, and at three o'clock in the afternoon, several people switched their eyes on the storefront, but there was still no trace of Jason.

Lu Weiwei first set up a temporary WeChat group, and pulled 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: "Lao Wang, I don't have anything abnormal here, what about you?"

Officer Wang: "I don't have it either, everything is normal, Jason's photo has been sent to you, pay attention, by the way, where are you Gu Chen?"

Gu Chen: "None." ”

Officer Wang: "......"

Lu Weiwei: "......"

Sure enough, it is the attribute of a provincial brother.

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 he didn't find Jason's haunt, and he couldn't help but be alert to this guy.

At this time, Linda, who had nothing to say for a day, finally sent a message.

Linda: "Jason asked me to bring the money to the Jasmine Milk Tea Shop to trade, I'm already on the road now, do any of you have anyone in the Jasmine Milk Tea Shop? ”

Officer Wang: "Who's in the Jasmine Milk Tea Shop?"

Lu Weiwei: "I'm not here. ”

Wei Junzhi: "I'm not here either, I'm with Linda." ”

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

......
