Rook's voice fell. Outside the door, footsteps sounded, and a tall man walked into the conference room with three of his men.

Liu Fei hurriedly led everyone to greet him.

After a period of greetings, Liu Fei learned that the one who came to lead the team this time was a deputy director of the Technical Investigation Department, that is, the tall man, named Zhang Tianzuo, is a doctorate expert official, Zhang Tianzuo did not stay for a day after he came, and directly asked to enter the scene to check it out, Liu Fei and the others naturally couldn't ask for it, and immediately took Zhang Tianzuo and others to the scene of the crime.

After entering the scene of the crime, Zhang Tianzuo carefully checked the situation at the scene, and then took a miniature tester from the hands of several subordinates, turned on the switch, and after a while, after that, when the tester showed a series of English letters, Zhang Tianzuo was taken aback, nodded vigorously and said: "Amazing, amazing, it is actually the latest toxin of phenylcyclic ether, and it is also a synthetic version on the spot, master, master!" ”

Liu Zan also heard a little about this toxin, and hurriedly asked: "Director Zhang, you said that this toxin is actually a synthetic version on the spot, what is going on?" ”

Zhang Tianzuo stood up, pointed to the two pots of violets in the room with his hand and said, "Do you see those violet flowers?" ”

Everyone nodded, and Zhang Tianzuo continued: "Those two pots of flowers usually look beautiful and charming, and the aroma is compelling, but when they encounter a colorless, odorless and non-toxic gas called benzenic ring ether, the pot of flowers will become a deadly killer, and after the fragrance of the flowers and the phenylcyclic ether are encountered, it will quickly produce a deadly poisonous gas similar to sarin gas phenylcyclic ether, which is also colorless and odorless, but it can destroy people's central nervous system in an instant, making people die unconsciously, Did you see how those people died? The expression before death is still on the face, which is the unique effect of phenylcyclic ether! This combination was discovered by a scientific research institute in the United States in August last year, and it caused a strong international shock as soon as it was announced, and then there were two homicide cases that used this combination one after another, so Interpol and the Internet search engine company cooperated to quickly delete the news, so not many people knew this information. I really didn't expect that there would be such a master who knew about this in this place in Dongning City, which was really not simple. ”

Liu Zan asked: "Director Zhang, since phenylcyclic ether can be fatal in an instant, how did the murderer escape?" Could it be that he just plugged his nose and would be fine? ”

Zhang Tianzuo shook his head lightly and said: "That's not good, phenylcyclic ether can directly enter the body from the pores of the human body and spread rapidly, unless the murderer is wearing a biochemical protective suit, it is difficult to leave calmly, but there is a simpler and more practical way to ensure that the murderer is not poisoned, that is, when the murderer committed the crime, he had a piece of violet rhizome in his mouth, and after going back, he used this rhizome to soak in a glass of water to drink, basically there was no problem!" ”

"Ah, so amazing?" Everyone was taken aback, although the people from the Provincial Public Security Department had rich experience in handling cases, it was the first time they had heard of such an unbelievable murder method.

Liu Fei immediately said to Liu Zhan: "Liu Zhan, you immediately take someone to search Jiang Biao's office, and carefully separate all communication tools and suspicious physical evidence!" ”

Liu Zan said with some concern: "Secretary Liu, this is ...... Is this good? ”

Liu Fei waved his hand and said, "Don't worry, I can be sure that Jiang Biao is the murderer!" All we lack now is evidence! ”

Seeing Liu Fei's affirmation, Liu Biao did not hesitate to wave at ** and others, and rushed to Jiang Biao's office, and at this moment, Jiang Biao has been detained at the scene because he is a key suspect, and he followed everyone with him, and after hearing Liu Fei's order, his face immediately turned blue, but he quickly calmed down again.

From beginning to end, the corner of Liu Fei's eyes never left Jiang Biao's face, and after seeing the change in his face, Liu Fei's mouth couldn't help but show a sneer.

After more than 20 minutes, Liu Zan rushed over with a group of subordinates, his expression was a little ugly, and when he walked to Liu Fei's side, he just had an extra PDA handheld computer in his hand, but nothing else!

"Secretary Liu, only such a device was found at the scene, and there was nothing suspicious about the others." Liu Zan said with a frown.

Liu Fei smiled and patted Liu Zan on the shoulder and said, "Don't worry, give me the PDA!" ”

After speaking, Liu Fei took the PDA, connected it with the laptop with a data cable, and the keyboard in his hand snapped, and soon, all kinds of data and logs on the PDA quickly fell out! After Liu Fei finished operating everything, he let the various logs be printed, Liu Fei's sharp gaze fell on Jiang Biao's face and said coldly: "Director Jiang, you are really a hacker master!" Silently invaded the database of the server of the monitoring center of the city bureau, and deleted nearly 20 seconds of video recording, all of which was done seamlessly! ”

After listening to Liu Fei's words, Jiang Biao's face was a little embarrassed, and he said with an indifferent expression: "Secretary Liu, where did your words come from, how could I hack into the database of the monitoring center!" Do you have any proof? ”

Liu Fei said coldly: "The evidence is here, see for yourself!" After speaking, Liu Fei snapped the stack of log records printed out by ** and fell down in front of Jiang Biao and said, "Jiang Biao, take a look for yourself!" Don't think you're the only one who's a master hacker! Actually, you're still tender! ”

When Jiang Biao picked up the log records that Liu Fei threw over, his face was pale and pale, and his hands trembled, and when he raised his head to look at Liu Fei, his hands were already trembling, and his voice was a little hoarse and said, "Liu Fei, how did you call up these logs?" I've erased all of these records! ”

When Jiang Biao asked this sentence, everyone basically knew that the real murderer was in front of him, but how did Liu Fei find out? You know, Liu Fei is a layman! Therefore, everyone's eyes fell on Liu Fei.

Liu Fei glanced at Jiang Biao with disdain and sighed and said: "Jiang Biao, originally with your technical level, not to mention in Dongning City, even in the entire Baiyun Province, you can be regarded as one of the best, but it's a pity that you met me!" Even if you're 10 times more skilled, you can't! The reason why I was able to judge that you were the murderer was because after watching the video surveillance footage, when you went to the scene of the crime, I carefully studied the video footage and found that the video surveillance video was missing about 20 seconds of data. I found that there was once an IP address of 192.136.1.132 computer has invaded the monitoring center server host, I called the information center network management to ask, confirm that this IP address is your computer, and at this time, it happens that your computer is open, so I followed the network into your computer, after a search found that you are a very shrewd person, your computer did not leave any operation records, but by a PDA remote control through your computer into the monitoring center server, I believe, you must have found a lot of reasons to explain why your computer is shut down, but I can tell you plainly that it was all in vain. ”

After Jiang Biao listened, he said with a wry smile: "Then how can you be sure that I am the murderer?" You know, I was in the cinema! Deputy Director Wu can testify for me. ”

Liu Fei sneered: "Hmph, maybe you once entered the cinema with Deputy Director Wu, but I asked Deputy Director Wu before, in the middle of the movie, he remembered something and wanted to ask you for instructions, but found that you were not in the cinema, he was a very responsible comrade, and even looked for the toilet of the movie, but he didn't find you!" Although you later went back at the end of the movie, you forgot that although you remotely mastered the spherical camera inside the city bureau and turned away when you went over the wall, you forgot that the city security bureau is very close to the intersection, and the intersection also happens to have a spherical camera rotating regularly for monitoring, and the place you want to climb over the wall is exactly the monitoring range of that camera! After I found out that the data was erased, I immediately asked someone from the traffic police to send me the surveillance video footage of the intersection near the intersection for 30 minutes during that time! See for yourself! As he spoke, Liu Fei took the laptop, clicked on a video, and dragged a video forward, and soon flashed the scene of a short and fat man climbing over the wall in the video screen, although the picture is not clear because of the distance, but the body shape is very similar to Jiang Biao!

Jiang Biao said coldly: "Liu Fei, you should know that there are no footprints of mine at the scene of the crime, why do you say that I have been to the scene of the crime?" ”

Liu Fei sneered: "Liu Zhan, are the people from the anti-smuggling team here?" ”

Liu Zan nodded and said, "I already called them just now." ”

Liu Fei smiled: "Let them in!" ”

Soon, ten members of the anti-smuggling team walked in with ten German black shell police dogs and reported to Liu Zan and Liu Fei.

Liu Fei asked the members of the anti-smuggling team to command the police dog to smell the smell of Jiang Biao's body, and then asked the members of the anti-smuggling team to take the police dog to search for a pair of shoes with Jiang Biao's body odor! Half an hour later, a member of the anti-smuggling team returned to the scene with his police dog holding a pair of shoes and placed them in front of Jiang Biao.

At this moment, Jiang Biao's face turned completely white, and his legs began to tremble.

As soon as the experts from the Provincial Department of Aircraft Investigation looked at the shoes, they immediately said loudly: "That's right, what didn't find the owner was the shoe prints of the shoes." ”

Liu Fei's gaze shot at Jiang Biao, and said coldly: "Jiang Biao, what else do you have to say, now you can explain, who is the instigator to plan this matter!" ”
