Li Bing was overjoyed and carefully took the laptop handed by the criminal policeman. In the conversation with the technician, Li Bing learned that when the technician tested the computer, he not only found a large number of computer viruses, but also found a Trojan horse program in the computer.

After sending off the technician, Li Bing carefully opened the laptop. Since the criminal police team had cracked the boot code, Li was not asked to say any operation, and the computer smoothly displayed the desktop status that could be used normally after a while.

Li Bing had no doubt about what the criminal police and Team Song said. He no longer carefully checked what was in the computer, first, the time was pressing, and he was left with less than 24 hours, and secondly, because the technicians of the criminal police team were naturally not mixed food, and if there were any clues, they should have found out a long time ago.

What Li Bing desperately hopes for at the moment is that he can be on Xiao Keyi's QQ, so that he can find clues from her chat records. He also knows that Tencent's technical strength is strong, and it changes the encryption method from time to time, and it is pure nonsense to crack the password in a short time.

The only way to know Xiao Keyi's QQ password is to ask the criminal police team to apply to Tencent for investigation, but there is a complete set of legal procedures, and Li Bing has no time to wait.

His only hope now is to pin his hopes on the guessing method of cracking the code. Most people use computers on the Internet, especially people like Xiao Keyi who don't even have antivirus software and firewalls installed, and their security awareness is indifferent.

Looking at Xiao Keyi's personal identity information sent by Team Song to the criminal police along with the computer, Li Bing began to try to crack the password after silently praying to the sky.

To his great surprise, when he just typed in Xiao Keyi's birthday and hit the enter key heavily, Xiao Keyi's QQ avatar began to rotate, and after a while, it began to flicker non-stop, making a non-stop 'drip, drip' sound.

The surprise had not disappeared, and Li Bing was suddenly surprised again. Because a prompt pops up at the tray in the lower right corner, QQ may be insecure, and the last login location was in Baoji.

How is this possible? Xiao Keyi has not been at home and has not gone out, how can it happen that QQ has landed in Baoji? Li Bing hurriedly dialed Team Song's phone and unexpectedly learned from Team Song that before Xiao Keyi's accident, her husband Shen Kai's business trip was in Baoji.

It was Shen Kai who logged in to Xiao Keyi's QQ! An inexplicable excitement surged in Li Bing's mind.

From what Xi Keying told everyone, everyone learned that Xiao Keyi was lonely and lonely because he had been at home alone for a long time, and often logged in to the local city group for QQ chats. And in the process of chatting, I had an ambiguous relationship with an insurance company manager named Tao Ziwen.

Since this is the case, Xiao Keyi will never be stupid enough to let her husband log in to her QQ and expose her privacy. In other words, Shen Kai quietly logged in to Xiao Keyi's QQ number without Xiao Keyi's knowledge.

How could Shen Kai crack Xiao Keyi's password? Li Bing himself is a computer major, and he knows that it is almost impossible. Therefore, the only reason is that Shen Kai quietly installed a Trojan horse in Xiao Keyi's laptop to steal Xiao Keyi's QQ password when Xiao Keyi's QQ was not logged in but the computer was turned on when he was at home.

Such an analysis also matched the number with the Trojan program found by the technicians of the criminal police team in Xiao Keyi's laptop.

Shen Kai was lying, and Li Bing's heart immediately brightened. It seems that his own assumptions about Shen Kai are not unreasonable.

On the night of Xiao Keyi's first 'ghost', that is, the day Xiao Keyi was ready to attend a party in the same city, Xiao Keyi did go offline at 7:20 at night and left the house. As for the later suspicion that Xiao Keyi was hallucinating, that is, Xiao Keyi's QQ was still chatting with group friends online at ten o'clock, which is basically certain not Xiao Keyi herself, but the person who knew her QQ password, that is, her husband Shen Kai.

Today is August 29th, Xiao Keyi found out that the victim was on August 20th, so why did QQ show the last login, not only in Baoji, but also on the night of August 19th?

This proves that on the night Xiao Keyi was killed, there were still people on her QQ. Of course, that person can now be sure that it is her husband Shen Kai.

From this, Li Bing judged that on the night Xiao Keyi was killed, Shen Kai was indeed not present, he was really in Baoji. Then, the one who can kill Xiao Keyi is naturally her personal psychiatrist Xi Mengying.

The question arises again, since Shen Kai and Xi Mengying murdered his wife Xiao Keyi to death, why didn't he do it himself on the night of August 19th? Is it just to find an alibi for yourself?

Even if it was for this reason, why did he secretly go to Xiao Keyi's QQ again? Li Bingleng was stunned for a long time, and reluctantly found two far-fetched reasons for himself, that is, Shen Kai wanted to borrow the slap of QQ to test whether Xiao Keyi was asleep, so as to give Xi Mengying a hands-on command, or he wanted to see what his wife revealed on the Internet in order to prevent any flaws from being exposed after committing the crime.

Thinking of this, Li Bing's eyes couldn't help but light up, and he immediately checked the settings of Xiao Keyi's QQ number. Sure enough, Xiao Keyi's QQ number was set to local message roaming. In this way, Li Bing basically confirmed that Shen Kai's purpose of secretly going to Xiao Keyi's QQ was to be afraid that Xiao Keyi would realize something and reveal content that was unfavorable to him on the Internet.

A flashing blue avatar caught Li Bing's attention, and when he clicked on it, it turned out to be Tao Ziwen, a netizen with an ambiguous relationship that Xiao Keyi had revealed to Xi Mengying.

Tao Ziwen's message is very simple, only one sentence: "Keyi, why are you?" I was scared to death, and when I heard rumors that there was a throat-slitting murder in your villa, I thought it was you. Damn it, I should have smacked myself in the mouth for such a cranky idea. ”

Li Bing was stunned for a while, and he called up the conversation record between Tao Ziwen and Xiao Keyi. From the long record, Li Bing saw that Xi Mengying did not talk nonsense, Xiao Keyi did have an ambiguous online romance with Tao Ziwen, but the two had never met, and even Tao Ziwen had never seen a photo of Xiao Keyi.

Li Bing thought for a long time, and pressed a line to reply: "Tao Ziwen, tomorrow is Sunday, you should rest, right?" Don't tell anyone about it, we'll meet at 9 o'clock in the morning at the Blue Rose Teahouse. Here's my phone number, you wrote it down, and give me your phone number at the same time. ”

On the other side of the computer, Tao Ziwen was obviously overjoyed, and quickly exchanged mobile phone numbers, looking forward to the first appointment with the lover of his dreams tomorrow.
