"Do you know what this place is?"

"Yes, NSA. ”

"Do you know why I arrested you?"

"Does it have something to do with me sending Morse code with electromagnetic waves?"

Watching the interrogation of Shi Xiaoyu by Zhang Chunhe and Cui Luyi in the interrogation room through the surveillance, Lin Jia didn't expect Shi Xiaoyu to be so cooperative. Before Zhang Chunhe pointed it out, Shi Xiaoyu had already admitted it.

"How many times have you sent Morse code, and to whom have you sent Morse code?"

"Four times. But it is not known who the recipient is. ”

"Is it possible?"

"That's exactly what happened. Someone asked me to send Morse code at a designated time and place, but never told me who it was sent to. I didn't know exactly what the code stood for, and I didn't even know it was Morse code at first. ”

"Who told you to do it?"

"I don't know. ”

Hearing this, Lin Jia's heart tightened outside, and he couldn't help but secretly doubt in his heart: Could it be that his speculation was wrong again, Shi Xiaoyu was not a big fish as he imagined, but just a small fish secretly manipulated by someone?

"Shi Xiaoyu, do you still need me to remind you what the National Security Bureau is? Do you think you can fool the past if you don't admit it?"

"I know, so I'm not going to hide it. As long as I know it, I will definitely confess truthfully without being reminded by you. ”

"Tell me in detail who instructed you to send Morse code using the principle of electromagnetic waves. Also, who taught you how to send Morse code? ”

"I think you've searched my quarters. Looking up at Zhang Chunhe, seeing Zhang Chunhe nodding, Shi Xiaoyu continued: "Then did you find a few pieces of printing paper in my residence?"

"What's on paper?"

Because Zhang Chunhe did not answer his question directly, Shi Xiaoyu didn't know for a while whether Zhang Chunhe was testing him or had another purpose. However, he replied honestly: "Although I don't know what the purpose of the man asked me to do that, I guess from the other party's behavior of giving me a reward ranging from 5,000 to 10,000 yuan every time, it must not be a good thing." So I kept the instructions that the man gave each time, and the techniques used to teach me how to send Morse code. ”

"Let's start with the time and content of the first order you received. ”

"The first time was on May 14th, and I remember it was Thursday. When I returned to the rental house in the evening, I somehow found an envelope in my room, and opened it to see that there was a piece of writing paper in it. ”

Lin Jia, who was outside the interrogation room, was taken aback when she heard this, because she had been present during the search of Shi Xiaoyu's residence. It's just a one-bedroom unit with only very simple daily necessities, and there are no things such as writing paper that Shi Xiaoyu said. Lin Jia didn't believe that he had missed anything during the search. This is also the reason why Zhang Chunhe in the interrogation room quietly asked Shi Xiaoyu about the content of the printing paper.

The content of the paper is not long, and it roughly says something like this: Tomorrow night at 8 o'clock on time to the Guangming Road Dorsett Bathing Center, the waiter will give you the key to the No. 174 cabinet. It contained $5,000 and a note. If you want the $5,000, just follow the note.

Although I also wondered if it was a prank made by a buddy, I happened to lose only a few dozen yuan that day, and it was time to pay the rent in ten or so days, so I still went to the Emgrand bathing center on time with a fluke mentality the next day. What I didn't expect was that when I got the key to the cabinet handed to me by the waiter, I knew it wasn't a prank when I saw that it was number 174. ”

"What's the content of that note?"

"At a rate of six times per second, the intervals are as uniform as possible. For example, in the group of numbers 8467, the first number 8 is pressed 8 times in a row at a frequency of six times per second, and then pauses for half a second, and then pressed 4 times in a row to form the number 4, and then pauses again for half a second. 6 and 7 below and so on. ”

Seeing that Shi Xiaoyu stopped at this point, Cui Luyi, who felt that she had no head or tail, couldn't help but ask: "Is there anything else?"

"No more. These words were written on the note, and I was very confused at the time, not knowing what it was. ”

"What about the five thousand dollars?"

"Inside a brown paper envelope. ”

"And then, what did you do?"

"At that time, I was almost crazy poor, and as long as I had money, I didn't care about anything else, so I went to take a bath. When I came out after more than an hour, I changed into a bathrobe and planned to go upstairs to the lounge area for a massage, and when I opened the cabinet to get the cigarettes in my clothes pocket, I found that there was one more thing inside. ”

"Is it the device under the bed in your apartment that emits Morse code?"

"Yes. Plus, there's a note pressed underneath the thing. ”

"Contents. ”

It begins with the following paragraph: After ten o'clock, I rushed to the faculty dormitory on the west side of the campus of the University of Science and Technology, and sent out the following six sets of numbers according to the method described in the previous note. Here are six sets of numbers. ”

"What exactly is the number?"

"I only remember that the first set of numbers was 58, and the next five groups were all made up of four Arabic numerals, and I can't remember. Shi Xiaoyu paused and said, "The note is under the mattress on the bed in my room, and it is placed together with other writing paper." ”

Zhang Chunhe did not continue to ask Shi Xiaoyu about his next trip to the University of Science and Technology, but instead asked: "Is the waiter who gave you the key to the cabinet male or female, how old is he, what are his characteristics, did you know him before?"

"Twenty years old and less than thirty years old, a woman, very beautiful. He is more than 1.6 meters tall, has long hair in a shawl, has a very slender figure, and his skin is quite white. I didn't know her before. ”

"If you see her again, will you still recognize her?"

"It should be. ”

"Did you see her again at the Emgrand Bathing Center later?"

"Nope. ”

"How long has it been since you went to the Emgrand Bathing Center again?"

"A week. ”

"Didn't you inquire about the waitress's whereabouts?"

"No, I didn't dare. ”

Lin Jia outside the interrogation room was not calm at this time.

First of all, when searching Shi Xiaoyu's residence, let alone under the mattress on the bed, even if it was under the bed, it was carefully inspected, and no words and paper that Shi Xiaoyu said were found at all.

It can be seen that it doesn't look like Shi Xiaoyu is lying. That is to say, before the National Security Bureau searched Shi Xiaoyu's residence, someone took the first step to destroy all the incriminating evidence left by Shi Xiaoyu.

Who could it be? Who would be so well-informed?

After all, Zhang Chunhe and Cui Luyi have always been very careful when investigating Shi Xiaoyu. Including the arrest of Shi Xiaoyu, the police station in the jurisdiction took him away first in the name of arresting gambling, and then the National Security Bureau quietly escorted Shi Xiaoyu back.

Secondly, why did the person who manipulated Shi Xiaoyu behind the scenes choose to instruct Shi Xiaoyu to act on the same night that Yang Yuting went to the Emgrand Bathing Center.

As for why the other party chose to hand over the electromagnetic wave transmitter and pay Shi Xiaoyu in the bathing center, Lin Jia understood the intention after a little thought.

After all, the bathing center is a public place, and appearing in the changing area as a waiter naturally does not attract anyone's attention. Therefore, it is not only convenient to do things to the watch in Yang Yuting's cabinet, but also to put the 5,000 yuan reward and the piece of paper that ordinary people can't see the clue in it, just to see Shi Xiaoyu's reaction. If Shi Xiaoyu showed that he had taken the money, but ignored the meaning of the paper, then the person hiding in the shadows could take the money and the paper again while Shi Xiaoyu was taking a bath. And Shi Xiaoyu's reaction is exactly what the people behind the scenes want to see, so he can move on to the next step.

Obviously, the people behind the scenes have fully understood Shi Xiaoyu's habit of seeing money and his financial situation. Even the details of Shi Xiaoyu's loss of money are well understood. So he basically concluded that Shi Xiaoyu would not let him down, so he made such a careful arrangement.

This is very much in line with the style of the person who single-handedly designed the illusion of the car accident scene that caused Zhou Wei's death.

Lin Jia knew very well that it was impossible to find the waiter who handed over the key to Shi Xiaoyu's No. 174 cabinet in the bathing center, but he immediately ordered the action team to divide into two routes, all the way to the Emgrand bathing center, investigate the waiter on duty on May 15, and call up all the information of the waiter on duty that night, and screen them one by one.

The other went to Shi Xiaoyu's rental house again to retrieve the nearby surveillance data to see if he could find the person who entered it before them and destroyed the evidence that Shi Xiaoyu had kept.
