"Don't talk about this for now."

Shen Jiaze waved his hand and told Li Yu not to speak. He looked at the USB flash drive from front to back, left and right, then inserted it into the USB flash drive of a computer, then opened a program and typing on the keyboard. Li Yu only saw a bunch of symbols scrolling on the screen, and then, the beating pointer on an instrument placed next to Shen Jiaze suddenly fell silent.

"Okay, I've turned off the signal."

Shen Jiaze sighed and said. After seeing the appearance of the USB flash drive just now, he determined that the signal transmitter in the USB flash drive must be controlled through the data interface. He is in this line of work, and it is easy to crack the control command. Now the signal in the USB flash drive has been turned off. If someone uses a tracker to track the location of the USB flash drive, he will definitely have lost his target at this time.

"Now we can talk about your classmate. What are your classmate doing? Does he have any conflicts with you?" Shen Jiaze asked.

Li Yu said: "She is the girl who serves dishes in a restaurant. Not only does she have no conflicts with me, she is also a friend. Just the day before yesterday, I saved her life from the criminal. By the way, this USB flash drive was discovered after she went back the day before yesterday."

"Badman, what kind of gangster?" Shen Jiaze asked.

Li Yu briefly explained what happened the day before yesterday, but he couldn't tell what happened to the criminal. However, after this statement, he suddenly had a guess that this USB flash drive might have something to do with the criminal.

"Is that gangster took advantage of the chaos to put the USB flash drive into your classmate's schoolbag?" Shen Jiaze also thought of this. "This USB flash drive may be some evidence of criminality. He was afraid that it would fall into the hands of the police, so he used the hostage to stuff it into your classmate's schoolbag. Because there is a tracker in the USB flash drive, he, or his accomplices, can find your classmate according to the instructions of the tracker and then take the USB flash drive away."

"This is the most likely reason." Li Yu nodded and said.

"If this is the case, then this USB drive..." Shen Jiaze pointed at the USB drive with his finger, feeling panic like holding a bomb.

A USB drive that can be protected by kidnapping hostages, and it is a USB drive with its own tracker. Can there be only some ordinary content? Shen Jiaze himself has just developed a pet tracker, and he knows the difficulty of this technology. The other party can integrate a transmitter with more power in such a large space as the USB drive, and its technical level is much higher than that of him. This technology is not something that a private institution can have. It may be that there is national level power behind it.

"Brother Shen, can you see what's in it?" Li Yu said.

"You can see it... But Li Yu, the things in it may not be what we should see." Shen Jiaze reminded.

Li Yu didn't have that much fear. Besides, this happened to him. If he didn't understand the background, he wouldn't know what the reason for his head fell out. He said, "Brother Shen, let's take a look first. I can't be stared at in a daze. If there is nothing wrong with this USB flash drive, then we're guessing it wrong?"

"Okay, let's see what's going on."

Shen Jiaze agreed, and he clicked on the resource manager and began to observe the contents of the USB drive. But what made him feel strange was that the storage of this USB drive was just a Win7 system, and there were no other files other than that. Shen Jiaze opened a software to scan the USB drive thoroughly, but found nothing unusual.

"It's strange, is a Win7 system worth so sneaking?" Shen Jiaze said to himself.

Li Yu reminded: "Brother Shen, I heard from Senior Brother Ge that he has some action movies that he doesn't want Xu Yingying to know, so he uses some hidden files to store them on the hard drive, so that others can't see them. Is there such hidden files on this USB drive?"

Shen Jiaze shook his head and said, "I thought of this too. Look, I have scanned the entire USB drive space just now and found no hidden content. The same is true for space. This USB drive is 16G, and now the remaining space is 12G. The files in the Win7 system directory are exactly 3.9G, which adds up... huh, 3.9G?"

"What, Brother Shen, is there anything wrong?" Li Yu asked sensitively.

"It's wrong." Shen Jiaze said. He opened the drawer and found a CD from somewhere. He inserted it into the CD-ROM drive and read it. Then he sneered: "I just said something was wrong. The genuine Win7 system is 3.3G, and there is 3.9G on this USB flash drive. The mystery must be in the extra 600M file."

Li Yu couldn't understand what Shen Jiaze meant. His understanding of computers was still in a very early stage, so it would be good to know the size of the space. Shen Jiaze didn't explain it to him. He opened two resource manager windows and compared them. Sure enough, he found two files that did not belong to the Win7 system in the USB flash drive. The names of these two files are very similar to those on the installation disk. At first glance, they could not have imagined that they were two fake files.

"It's these two files. This USB drive is to pass these two files." Shen Jiaze pointed at the names of the two files and said to Li Yu.

"What's in it?" Li Yu asked.

Shen Jiaze shook his head and said, "I can't crack it. These two files should be encrypted and compressed in a special way. Unless you find the corresponding compression software and you also need to know the decompression password, it is impossible to open it. In addition, I think since the other party has spent so much effort to hide these two files and also added a tracker to the USB flash drive, the content of the file must be extraordinary. If we read it, it may cause trouble. Don't you know a truth? The more you know, the more dangerous it is."

Li Yu nodded. Shen Jiaze's words made some sense. He was now able to confirm that there must be something wrong with this USB flash drive, and it might involve a shocking case. He had nothing to do with this case, but now he accidentally brought it in. The USB flash drive is in his hands and there are two followers outside the door. These are problems he needs to solve. If these problems are not solved, trouble will continue to occur.

"Brother Shen, what do you think should be dealt with this USB drive?" Li Yu asked.

Shen Jiaze thought for a while and said, "There are two solutions. One is to completely destroy the USB drive and pretend that we have never seen this USB drive. The advantage of doing this is to be done once and for all, but the disadvantage is that if others know about this, we can't explain it clearly."

"What about the second plan?" Li Yu said.

"The second solution is to hand over the USB drive to the public security department and explain to them that we have not read the contents of the USB drive. However, it is hard to say whether they believe it or not, and it may be very troublesome."

Li Yu said: "What if I hand it over to them secretly?"

"Secretly?" Shen Jiaze thought for a moment, nodded, "This is also a solution, it is better than giving it to them directly."

"I think so too, so let's do it." Li Yu immediately made up his mind.

Shen Jiaze's first plan does sound more safer. Once the USB drive is destroyed, the public security department will not be able to find out how to investigate them. They can solve this problem once and for all. But Li Yu always feels that there is something wrong with this plan, because there are some clues to solving the case in the USB drive, and the police may be waiting for these clues to solve the case. If they destroy the USB drive, then a major case will become a headless case.

Li Yu didn't think he was very enlightened, but he still chose to stand on the side of the police. The owner of this USB flash drive should be the criminal who hijacked Zhou Zijun. How could Li Yu let him get away with it?

"There is another problem, which is the person who is following you. What are you going to do with it?" Shen Jiaze reminded.

Li Yu smiled and said, "This is very simple, I'll solve it."

Outside the gate of Jin Fortune Center, two men were hiding behind the bushes, staring at the gate without blinking, waiting for the people they were following to come out.

These two people, one named Miao Yucai and the other named Gu Rongxiang, were both Bi Jinan's accomplices. The day before yesterday, they received a notice from Bi Jinan and agreed to pick up the goods in the old place. As a result, the time passed, but Bi Jinan did not show up, so they knew that something was wrong with Bi Jinan.

According to the plan they agreed upon, once Bi Jinan is targeted by the police, he will discard the USB drive he received, which will not only avoid the secret leakage, but also make it impossible for the police to determine Bi Jinan's identity. On the USB drive, there is a long delay signal generator that can send a pulse signal every few seconds, and can be located with a special receiver.

Miao Yucai and Gu Rongxiang waited for a day, and then went out with the signal receiver to look for the USB flash drive. After several twists and turns, they finally determined that the USB flash drive was located in the migrant workers' cram school on the edge of the city.

The two of them did not dare to rush into the school to grab the USB flash drive, but waited outside the school, ready to wait for the rabbit. After Li Yu came out, the two of them targeted him and followed him, but could not find a chance to start. Seeing Li Yu entering the Jin Fortune Center, the two of them were afraid of exposing their Xingzang, so they could only hide outside the door as usual and wait for Li Yu to come out.

After Li Yu entered the door, the signal from the tracker still spread out intermittently, but after a while, the signal suddenly stopped. Miao Yucai and Gu Rongxiang were not surprised that this pulse signal was also a radio wave and could be blocked by some metal appliances. Just like if you put your phone in a metal storage closet, the signal could not be transmitted.

"Old Gu, why has this kid been in for so long and hasn't come out yet?" Miao Yucai lowered his voice and asked Gu Rongxiang beside him.

"How could I know!" Gu Rongxiang said angrily, "At first I said I would stop him. You must say that there is someone next to me, so it's hard to do it. If this kid goes to sleep in this building, wouldn't we have to wait for a night?"

"No, am I out now?"
