"Can you see the introduction and information about this object?"

Sima Qiqi looked at Xie Junjie and asked.

Xie Junjie had already re-lit a cigarette at this time, turned his head to look at Sima Qiqi, Xie Junjie clicked the mouse, got out of the way and said: "The details of this thing, I know that lawyer Sima You will definitely say so, I investigated all the relevant information by the way when I just investigated the source of this thing, please take a look!" ”

The three of them hurriedly came to the computer screen and read out the information. "The Micro Health Monitor, created by C&A, aims to help everyone monitor their physical condition and avoid inaccurate treatment due to unclear explanations when seeking medical attention. Doctors can use this device to supervise patients, just wear it on their ears, and the data will be updated in real time and uploaded to their mobile phones. Data such as blood oxygen content, blood flow rate, blood pressure, etc. can be checked by the micro health monitor. ”

After reading the promotional materials of the miniature health monitor, he looked at Sima Qiqi and said, "These seven are all elderly, and it is not surprising that they have such a device." ”

Sima Qiqi looked at Xie Junjie and asked respectfully: "Mr. Xie, you are an expert in computers, I would like to ask, can this miniature health monitor be hacked by hackers?" ”

Xie Junjie was leaning against the wall smoking a cigarette at this time, hearing Sima Qiqi ask, there was no trace of expression change on his face, Xie Junjie thought about it, flicked the cigarette ash and said slowly: "If this monitor wants to update the data in real time, and the user can view it with a mobile phone, it will definitely be hacked, but the hacker is not this monitor, but the computer behind the monitor, the data detected by these monitors will be returned to the running computer, and the running computer will then send back the data sent back by each instrument back to the user's mobile phone corresponding to each instrument." Therefore, by invading the relevant computer, the purpose of controlling the monitor can be achieved. ”

"Qiqi, you asked this because you suspected that Yuan Ruixue was invading the monitors of these seven people before she went to the café with her notebook, so she could go directly to her own home."

looked at Sima Qiqi with a puzzled look and asked.

"Well, I think I know."

Xie Junjie took a deep breath of cigarette, slowly exhaled it, and said unconsciously: "If the woman you suspect is really a computer genius, then she uses the network of the café outside to surf the Internet, and she can use the network of the café to re-encrypt her IP address, so that even if she invades the relevant computer and leaves traces, she will not find her head." In addition, in order to retain customers, the network used by the café can ensure the speed of the Internet, which I think is the reason why the subject of your suspicion chooses the café. ”

Hearing Xie Junjie say this, he gasped, it seems that this seemingly harmless Yuan Ruixue has a deep scheming beyond ordinary people, what ordinary people can see is the side that Yuan Ruixue shows and wants others to see, and his real face seems to be covered by the black fog, you can't see the real situation behind the black fog at all, maybe a monster is opening its mouth with a bloody basin, waiting for the opportunity to swallow the prey in one bite.

Thinking of this, he couldn't help but shudder, Sima Qiqi heard Xie Junjie's explanation and strengthened the guess in his heart, the reason why Yuan Ruixue appeared in the café with a laptop when all seven of the dead died unexpectedly should be because he used his unknown computer talent to achieve an impossible murder.

Sha Yu said with a blank face: "I understand what you say, even if these seven people are wearing health monitors, then how did that woman kill people, even if she invades the background system, she can only see the relevant data, how to kill people, do you still make those monitors become murderous weapons and explode?" ”

Sima Qiqi thought for a while and said: "I want to be similar to the situation that Mr. Xie said before, it is like having a problem with the computer decompressor, when the file is decompressed, the voltage is too high, causing the battery to explode. I think Yuan Ruixue should have used some method to make this monitor her killing tool. Can you help me look it up? ”

Sima Qiqi looked back at Xie Junjie and asked.

Xie Junjie shrugged his shoulders and said: "In principle, there is no problem, but the actual operation is difficult, first of all, I don't know what program you suspect the person has modified, then I want to investigate only two ways, one is more stupid, that is, to enter the background computer of this company to view all the programs and compare them with the previous programs." The impossibility of this method is that the other company will definitely not give me the programming raw data, so I don't know what to look up when I go in. The second is relatively simple, you give me the suspect's laptop, and I use my computer to check the suspect's computer and find the relevant footprints. ”

"Stop, don't think about what you said, neither of these methods can be done, that's it."

"Isn't that another dead end, can you find someone to steal Yuan Ruixue's laptop?"

"There's a lawyer standing here, sir, can you say something reliable!"

After asking and answering with Sha Yu, Xie Junjie shrugged his shoulders when he heard the conversation between the two and said, "So I said, there is no problem with this in theory, but it is difficult to operate in practice, because there is no option to meet the conditions." ”

Before Xie Junjie's words fell, Sima Qiqi suddenly said: "It's not that there is no way, we can not have background data and Yuan Ruixue's computer, but we can find relevant people to take the monitor worn by the deceased before his death to check the inside, although I don't know what method Yuan Ruixue used, but there must be some changes inside this instrument." ”

When Xie Junjie heard Sima Qiqi say this, he said unhappily: "Check the instrument, I won't do such a low thing." ”

"Eh, great god, you are definitely not suitable for this kind of work that Qi Qi said, we have to find Zeng Dian and find it, this is his strength."

When Xie Junjie heard this, he seemed to be saying that Zeng Dian was more useful than him, Xie Junjie took a heavy puff of cigarette, spit the smoke out of his mouth, and looked at it indifferently

......

In the new week, he used his connections to get the health monitors of three of the deceased.

and Sima Qiqi took Sha Yu's car to Zeng Dian's house. Sha Yu held his thigh last night and begged bitterly, this has to decipher what method Yuan Ruixue used to carry out this mysterious killing, if Sha Yu is not brought, then Sha Yu's future magazine will not have first-hand information on deciphering this content, so Sha Yu does not want to be forced to beg shamelessly, so he has to agree to Sha Yu's plea.

As soon as he came to Zeng Dian's home, Zeng Dian looked at it excitedly, and said with a smile: "You kid, you haven't looked for me for a long time, what is the matter with coming to me this time, I have been watched again, and there are still other fun things that need to be asked for my help." ”

Sha Yu said impatiently: "Eh, buddy, I asked you to help analyze whether there are any changes in these instruments, can you do it?" ”

Zeng Dian saw Sha Yu take out three black square things and put them on the table, Zeng Dian picked up one of them and looked at it, and said calmly: "Oh, the latest health monitor produced by C&A, why are you interested in this?" ”

Hearing Zeng Dian say this, he hurriedly smiled and said: "Ouch, it seems that you will definitely be able to answer the questions in our hearts, we just don't know what is different from normal in these things, so we came to ask you to answer your questions." This is a problem that even Xie Junjie can't explain, and it can only be up to you. ”

Zeng Dian heard that Xie Junjie couldn't answer it, so he showed a smug smile, patted his chest and said: "That's natural, Xie Junjie can only program on the computer, how can he understand these electronic components." ”

Zeng Dian looked at Sha Yu and blurted out, "Yo, fat man, come and help!" ”

"Fatty?"

Sha Yu heard Zeng Dian also call himself fat, and looked at Zeng Dian with wide eyes, Zeng Dian looked at Sha Yu in surprise and said, "What is your figure not fat, do you call you thin?" ”

Sha Yu was angry when he heard Zeng Dian's words, and thought: "This Zeng Dian is comparable to Xie Junjie in terms of communication with people. ”

Zeng Dian was busy for half an hour to completely disassemble the three monitors, looking for the internal changes he didn't know what he was looking for. With no direction, Zeng Dian had to resort to the most clumsy comparison method, checking three monitors at the same time to try to find different places.

Zeng Dian was so busy that he was sweating profusely, and suddenly said excitedly and loudly: "Found it, find it, come and see." ”

With Sima Qiqi hearing Zeng Dian's shouts in the room, the two hurriedly came to Zeng Dian's room, Zeng Dian magnified the internal structure of the three instruments through a microscope and put the pictures on the computer, Zeng Dian pointed to the computer screen and said.

"This should be what you are looking for, there is basically no damage to the inside of these three instruments, but there has been a short circuit in the power supply and the transmitter."

"What happens to a short circuit?"

Sima Qiqi looked at Zeng Dian with a puzzled expression and asked.

Zeng Dian said very proudly: "A short circuit will increase the current instantaneously, although this instrument uses microelectricity, but once the short circuit current will increase dozens of times, but it will not cause damage to the human body." ”

Everyone sighed when they heard Zeng Dian say this, Sima Qiqi looked at the pictures on the computer with a disappointed face, suddenly thought of a key point, and hurriedly said: "Who said that it can't cause damage, it can cause damage." ”

Zeng Dian said with a disgusted face: "That electricity is not dead, why do you still doubt my professional level?" ”

Hurriedly piled up a smile and said: "No misunderstanding, I didn't question your professional level, what you said is that the current passes through the human body from the outside, but now this instrument is worn on the ear, if its current instantly increases more than ten times, then the enhanced current can temporarily destroy the central nervous system." A brief downtime of the central nervous system is enough to cause a person's death. ”
