The interrogation of Shi Xiaoyu is still ongoing.

However, whether it was Lin Jia outside the interrogation room, or Zhang Chunhe and Cui Luyi, who were interrogating Shi Xiaoyu, there was a question in their hearts at this time.

Although the technology of using electromagnetic waves for transmission has long been eliminated, the basic common sense is that as national security personnel, they are very clear. It is almost impossible to make a person who has never been exposed to telecommunication technology and has not undergone any training suddenly send electromagnetic wave information at a certain frequency. However, after preliminary investigation and Yang Yuting's confession, it was found that Shi Xiaoyu accurately sent out the words "58 version of "Romance of the Three Kingdoms" for the first time.

Is this possible?

So, Cui Luyi asked: "After you rushed to the University of Science and Technology, when you sent those six sets of numbers, did you succeed at one time, or did you go through many attempts?"

"Just once. ”

"How did you do that?"

You may not believe it. Shi Xiaoyu's expression was somewhat embarrassed and said: "When I was in prison before, because I was good at gambling, I couldn't find an ideal tool that could be used for gambling and not be discovered by the prison guards, so I thought of a method - guessing the time. ”

"What's the guess?"

"For example, the number of participants is limited to one minute, and the number of participants at a time is limited to two, and another person is counting at the watch, and the two people estimate the time at the same time. Whoever feels that the minute is up will say it. Finally, compare who guesses the closest minute and who wins. The winner sits in the bank, the loser replaces, and so on and so on. At that time, there were more than 20 people in the entire cell, and none of them could win against me. ”

"How did you do that?"

"Whenever I have free time, I look at the watch on the wall of my cell and tap my fingers with a regular pattern of secret. Within a few days, I managed to fix the frequency of tapping my fingers at about 350 times per minute, and the difference between up and down would not exceed ....... ”

Speaking of this, Shi Xiaoyu suddenly stopped. Because he seemed to understand something at this time, he looked at Zhang Chunhe in a daze for a long time before he asked tentatively: "Could it be that person knows some of my habits when I was serving my sentence in prison?"

"You've been in prison twice, guess which time gambling happened?"

"The second time. ”

Regarding Shi Xiaoyu's experience of serving two prison sentences, it is very clearly recorded in his archives, so there is no need to continue around this issue.

For a long time, two suspicious points that occurred at the scene of Zhou Wei's car accident have been bothering everyone, one is how the person who sent the signal to Wu Jian to attack Zhou Wei calculated the time so accurately, and the other is that after repeated investigations, it was found that there was nothing suspicious about the female driver of the car that caused the accident, that is, she was not an accomplice in Zhou Wei's car accident. But why did the mobile phone on the dashboard fall at the corner of the corner, so as to attract the driver to lower his head to pick it up, which eventually led to the accident in which Zhou Wei was hit and killed. If it's just a coincidence, it's too bizarre.

So Zhang Chunhe changed the topic and asked: "Let's tell me in detail about the second time I sent the electromagnetic wave signal." ”

"I remember very well that it was the early morning of June 15th, and like the first time, when I returned to the rental house around 2 o'clock, I accidentally found a note on the floor, and when I picked it up, I found that there was a phone card in it. ”

"The contents of the note?"

"Let me rush to Pinghe City the next morning and evening, change into the phone card I just got, and keep my phone on all the time. And before 5 o'clock in the morning of the 17th, he arrived at the turn of the last traffic light in the east of the city, and chose a secret place to hide.

I arrived at Pinghe City at six o'clock in the afternoon on the 16th, and after changing my mobile phone card, I went to the last traffic light in the east of the city in advance to look at the terrain and choose a hiding place in advance. He then returned to the city and found a small hotel to stay in, and did not get up at half past four in the morning to leave the hotel, and arrived at the pre-selected hiding place before five o'clock. ”

"No, you didn't go to the village south of the traffic light?"

"What am I going to do there? No. ”

"No, didn't you steal the electric car of the family at the entrance of the village?"

Although he asked like this, in fact, Zhang Chunhe knew it in his heart, he just wanted to trick Shi Xiaoyu into seeing if he knew it. Because Jia Wei and Zhao Zengyuan had brought back from the local police station to steal the electric car, the few fingerprints left on the door of that house were not compared in the fingerprint database, which means that the person has no criminal record. And Shi Xiaoyu, who has been imprisoned twice, must have fingerprints in the fingerprint database, if it was really stolen by him, it is impossible to compare.

"I didn't do it. Stealing an electric car is worth a few bucks, and taking that much risk? I never do anything like that. ”

"And then, what about later?"

"At five o'clock on time, I received a phone call, and the other party just said, 'From now on, you are not allowed to hang up, and after receiving the instruction, turn on and off the transmitter every second at intervals, and turn it on and off three times in a row to complete the task'. ”

"Is it a man or a woman, can you hear the approximate age of the other party?"

"It's a man, and I feel like I'm supposed to be forty or fifty years old. Shi Xiaoyu looked at Zhang Chunhe and said, "I have a phone recording." ”

This is what Zhang Chunhe and Cui Luyi, including Lin Jia outside the interrogation room, did not expect. not only tried to save the instructions given to him by the people behind the scenes, but even recorded the call between the two, which shows that Shi Xiaoyu is not a mindless person. Of course, I can understand Shi Xiaoyu's purpose in doing this, which is nothing more than to meet the extremely poor, so as to blackmail the people behind the scenes. In addition, you can also leave a way back for yourself after the East Window incident in the future.

"Where is the phone call recording now?"

"I was saved in an email address registered with a mobile phone number that I had stopped using before. ”

"E-mail address?"

“132*****819@。 ”

"Moving on to the situation on the morning of June 17. ”

"It should be around 5:40, and suddenly there was a 'send it immediately' command from the mobile phone, and I immediately followed what I had said in advance, and then quietly slipped away after turning on and off the transmitter three times in a row. ”

"Can you see the scene of the crash?"

"Nope. I just heard a 'bang', which was supposed to be the sound of a car hitting someone. ”

"What about the phone card that the person used to contact you?"

"I kept it with those letters. ”

Regardless of asking, it can be seen that the scene of Zhou Wei's car accident is not only three people as the serious crime team and the National Security Bureau have always believed - Wu Jian, Duan Chuyu, an assistant police officer who helped forge the scene, and Shi Xiaoyu, who sent a signal to Wu Jian, but four. The other one who sent instructions to Shi Xiaoyu was the most critical person.

Moreover, it is very likely that this fourth person is the person who formulated the car accident plan that killed Zhou Wei, and it is also very likely that he sneaked into Du Xiaowei's dormitory in the spring to steal her clothes, and even entered the bank to deposit money in the safe rented in the name of Zeng Cheng.

Lin Jia, who originally thought that Shi Xiaoyu was a big fish, was slightly disappointed when she heard this, but she faintly felt that it was not far from finding the fourth person who appeared at the scene of Zhou Wei's car accident, or that it was not far from solving the mystery of the car accident that happened to Zhou Wei - who was the person who was determined to kill Zhou Wei, what was the motive, how his bank card flowed out and went to the hands of the unknown person A, and the ownership of the line behind Mu Qixiong, including the "Old Buddha Club" and other issues can even be easily solved.

Quickly summarized the clues previously mastered in his heart, combined with the information revealed in Shi Xiaoyu's confession, it was found that the fourth person who appeared at the scene of Zhou Wei's car accident showed the following three characteristics:

First, this person knows Shi Xiaoyu's life and economic situation very well, including Shi Xiaoyu's situation when he was serving his sentence in prison.

Second, this person should be the one who tampered with Yang Yuting's watch and the radio of the retired female teacher who appeared in Labor Park. In other words, this person is very well versed in the working principle of electromagnetic transmitters.

Third, this person is the one who made a detailed plan to bribe and direct Zeng Cheng to fake the scene of the car accident and put Zhou Wei to death. Moreover, the iron powder core that Zeng Cheng used to tattoo Wu Jian must also come from this person.

Fourth, this person is meticulous and has a strong sense and ability to conduct anti-reconnaissance.

Coupled with the two important clues that have been mastered, one is the phone recording kept by Shi Xiaoyu, and the other is the fingerprints that appeared at the scene of the loss of the electric car and Du Xiaowei's dormitory, and successfully compared, Lin Jia immediately had the direction and focus of the next step in his heart.
