The waiter saw Sima Qiqi's surprised look, and he didn't know what to say for a while, and nodded stiffly.

Seeing the waitress nodding his head, he asked with a questioning expression: "Are you sure you read that right, the woman surnamed Yuan was programming that night, right?" ”

The waiter saw that he doubted himself, and said angrily: "This is natural, there were only a few customers after eleven o'clock that night, Miss Yuan was one of them, I refilled her a few times, I was also curious that Miss Yuan had been staring at the notebook that night, I also looked at her screen and found that she was programming, so I didn't bother her." ”

"How do you know she's programming?"

looked at the waiter with a surprised face, it seemed that what the waiter said made the others unbelievable, after all, Yuan Ruixue is just a person who studies psychology, and he is completely interdisciplinary with computers.

"Even though I'm a waiter in a café, I also have my own hobby, which is programming, and I also enrolled in a programming course."

Sima Qiqi saw the waiter's angry face, and hurriedly smiled and said, "No, we are not questioning you, we just think that Yuan Ruixue is still programming so late, and it seems that she has encountered a big problem at work." Do you know what program she was editing at the time? ”

"I don't know, although Miss Yuan didn't stop me from watching, but her program on it is too complicated, I'm just getting started, as if it's some kind of execution password modification or something, I saw that Miss Yuan was staring at the computer screen intently, and she didn't even drink the coffee when it was cold."

Sima Qiqi couldn't help but gasp when she heard the waiter's description, if Yuan Ruixue is really like what the waiter said, then it is Yuan Ruixue who hides one of her identities, which can only show that Yuan Ruixue's second identity hides some secrets, such as the secret of Yuan Ruixue's murder.

Sima Qiqi thought of this, looked at the waiter with a smile and asked, "You said that Yuan Ruixue stayed late that day, so how long did she leave, do you still know this?" ”

The waiter shook his head and said, "I don't know, I went into the warehouse to sort out the goods, but when I came out, Miss Yuan had already left, and it was already 12 o'clock when I came out." ”

"I know when Miss Yuan left that night, she left around 11:56, when I used my mobile phone to chat with my boyfriend, my boyfriend told me that it was 11:56 and hadn't gotten off work yet, then I saw Miss Yuan suddenly stretch and look relaxed, drank the coffee in the cup, got up to pay the bill and left the café."

"I guess the programming work is done, right?"

The waiter looked at the short-haired waiter and asked, the short-haired waiter shrugged his shoulders and said, "I don't know about this, but looking at her relaxed face, it should probably be what you said, I passed by Miss Yuan before and saw Miss Yuan frowning, as if she really had a big problem." ”

Sima Qiqi smiled slightly and said to the two: "Thank you, since my good friend is staying with you so late, it means that your environment must be very relaxing, and I will come to you next time if I work overtime at night." ”

"Welcome, welcome!"

The male and female waitresses said in unison.

The three of them left the café, Sha Yu carried a bag of coffee beans, Sha Yu told the two that this was a gift for becoming an annual card member of the café, looking at the corners of Sima Qiqi's mouth, patted Sima Qiqi's shoulder and asked, "Qiqi, why are you laughing, what have you found?" ”

"I found that the connection between Yuan Ruixue and the death of the deceased, although it is still very weak, but I know that this must be a breakthrough in these seven cases."

Hearing Sima Qiqi say this, Sima Qiqi took out his mobile phone and turned out the information on the death of the horse, pointed to the mobile phone and said: "At that time, the deceased's female companion was investigated by the police, and you can see when the deceased died." ”

"11:55 p.m.?"

Seeing the time and feeling weird, Sima Qiqi put the phone back in her bag and looked at it and said to Sha Yu: "Yuan Ruixue left the café at 11:56, which means that her programming work has been done before this, if she was not doing ordinary programming at that time, but writing a killing program, and when the program is completed, it is the moment when the deceased dies, of course she will look relaxed." ”

"Murder program, even if Yuan Ruixue is a computer genius, it is impossible to use a program to kill people, and it is not a science fiction movie."

looked at Sima Qiqi with a questioning look and said.

Sima Qiqi looked at Sha Yu, both of them had expressions of disbelief on their faces, Sima Qiqi said slowly: "Hey, yesterday you said, one said that the laptop is a book of life and death, and the other said that the computer is used to modify the radio waves to reach the frequency of killing, so the killing program is also possible!" ”

"How does the program kill people?"

Still asking Sima Qiqi, Sima Qiqi shrugged and said blankly: "How do I know this, hey, I'm a liberal arts student, not a science and engineering major, how do I know what strange technology can kill people thousands of miles away." Just like yesterday Xie Junjie also said that someone can make someone else's computer decompression system malfunction, if it is used to decompress files, the voltage can be increased instantaneously to achieve a killing effect. Maybe the program written by Yuan Ruixue can cause mobile phones or other electronic products to become murder weapons, what's so strange? ”

"I'm sorry to interrupt the reasoning of the two, you have been talking for a long time, you may not have found a key point, this point is that this man died of a stroke, he should be naked at that time, where does he have any electronics, does he control the pacemaker?"

Sha Yu said calmly.

Sima Qiqi didn't know how to answer Sha Yu's question for a while, and then saw Sima Qiqi's silence, not only did she not comfort Sima Qiqi, but then Sha Yu's question asked: "Yes, Qiqi, you still have to think of something, even if Yuan Ruixue can write any killing program, then how does Yuan Ruixue know when it is most natural for the other party to die?" ”

Sima Qiqi heard the tricky questions raised by Sha Yu and the two, shook his breath and said: "If I can guess that these seven murders will not be treated as accidental cases, it seems that I have really met an opponent, but what I want to know most now is whether Yuan Ruixue has computer-related skills." ”

The three of them returned to Xie Junjie's house, Sha Yu was holding a notebook at this time and burying his head in writing the clues of these days, Sha Yu said with a smile: "It's just strange, this will definitely be able to catch the reader's eyeballs, kill people with high IQ, leave no trace, well, when the time comes, I will divide it into several installments, announce a little every day, and announce a little every day, I have seen a lot of banknotes fall in front of me, hahaha." ”

Sha Yu was dreaming of using Yuan Ruixue to make his magazine make a lot of money, but in Xie Junjie's computer room, he looked at Xie Junjie with a complaining expression and said: "Great god, you are a great god, let you find Yuan Ruixue's information, you can't be so perfunctory to me, you have to find all the details, you will give me a psychology graduate, why didn't you give me the information related to her computer skills?" ”

Xie Junjie looked at him in surprise and said: "Ah, computer skills, you said that woman also has computer-related skills, impossible, I have already hacked the relevant computer to obtain the information, and there is no relevant computer skills on the data, did you hear it wrong?" ”

Sima Qiqi saw that he and Xie Junjie were about to quarrel, so he hurriedly pulled him aside, looked at Xie Junjie with a smile and said: "That's the case, let's go to the café today to investigate why Yuan Ruixue carried a laptop with him when the seven people died, and it turned out to be such a coincidence, there was a waiter in the café who also learned programming, and he said that Yuan Ruixue was sitting in the café on the night when one of the victims died, and was concentrating on writing a program." And the time when the program was written was exactly the time when the deceased died, so we came to ask you to see if we could find relevant information about Yuan Ruixue's computer skills for our reference. ”

Xie Junjie heard Sima Qiqi say this, his mouth was half open, the cigarette stuck to Xie Junjie's lips because of saliva, Xie Junjie heard Sima Qiqi say this, and it took a long time to react, and said to himself: "This is impossible, I use a system that I invented myself, anyone who wants to hide their whereabouts or other things will be dug up by my system, if this woman really has computer skills, my system should be able to retrieve, no, according to what you just said, This woman doesn't just have computer skills, she's supposed to be a genius, no one knows computers better than me, no one ......"

Xie Junjie snuffed out the cigarette in the ashtray, stared at the computer screen with wide eyes, and quickly operated on the keyboard with both hands, but every time he looked for Yuan Ruixue's information, Xie Junjie did not find relevant information about Yuan Ruixue's computer skills.

Xie Junjie grabbed his hair with both hands and shouted in pain, seeing Xie Junjie like this, he hurriedly comforted Xie Junjie. But it didn't work at all, Xie Junjie looked at it with a dejected look on his face and said.

"I didn't find it, why didn't I find it, is what you said true, is it true, this woman has computer talent, why did I hack so many computers, and I didn't find the footprints of her computer skills, not at all, you lied to me, right?"

Xie Junjie was like a crazy leopard at this time, suddenly Xie Junjie fainted on the ground, saw Sima Qiqi standing behind Xie Junjie, and said calmly: "He is too excited, I knocked him unconscious, let him rest." ”

After the two helped Xie Junjie to the bedroom to rest, they returned to the computer room, Sima Qiqi saw Yuan Ruixue's educational experience written on the screen, Sima Qiqi looked at it and said, "Do you have any impression of this school?" ”
