Since the formal experience activity did not start until 4 p.m., the group went back to their rooms for a rest after lunch.

Of course, the excited Qiao Erha didn't need any rest at all, but he was still frightened by Ji Jinyan's gaze, so he could only pull Xia Chengqi to complain, "I think Ji Shao is targeting me." ”

"We all slept too late yesterday and woke up very early today. He wants us to have a good rest, don't blame him. ”

Although Xia Chengqi's menstrual period was coming to an end, he was still a little tired physically, so he started taking a nap after a simple wash.

Qiao Shuyue breathed a sigh of relief, bored playing with her mobile phone.

In Ji Jinyan's room, private detective Du Qin is reporting on the follow-up of the case, "It is understood that the two suspects in the park shooting and the Ferris wheel shutdown incident were both tasked from the dark web, and after the fact, they got 4 and 2 bitcoins respectively. ”

"What? Dark Web? Ji Jinyan felt very familiar with this word, but he had no concept at all.

"It's the dark web that we can't usually see through retrieval and URL, and they are not regulated by the government, so the information in them is mixed, and there will be crime-related information released." Du Qin tried to talk about his understanding of the dark web.

"Wait a minute." After speaking, Ji Jinyan dialed the phone in Ji Shenxing's room, "Come to my room and call Cheng Yu." ”

After a while, Ji Shenxing, who was full of confusion, and Xia Chengyu, who was yawning, appeared in the room.

"Mr. Du will explain the specific situation, I think you two should know better than me what is going on." Ji Jinyan motioned to Du Qin to tell the progress of the investigation of the case.

Sure enough, Ji Shenxing and Xia Chengyu understood as soon as they heard it, and changed their previous relaxed looks to nervousness and anger.

"I'll go to my room and go to the computer." Xia Chengyu ran away.

"Do you have any previous order information?" Ji Shenxing began to dig more information points.

"At the moment, the transaction has been closed and there is no relevant information to retrieve." Du Qin shrugged, indicating that the previous case had no clue.

"Is the dark web hard to track?" Ji Jinyan finally spoke.

"It's not difficult, the information is easy to find, but the only thing that can prove the identity of both parties is the transaction payment path, but they use Bitcoin, which is currently the most secure, or the most uncrackable digital transaction." Ji Shenxing was also helpless.

"Can't crack?" Ji Jinyan has always believed that the information on the Internet is the most insecure, but he didn't expect that there is still unbreakable data.

"Yes, Bitcoin uses blockchain technology, which is the most advanced encryption algorithm at the moment, and even the creator of this technology is currently in a state of secrecy, because no one can find him through Internet technology." Ji Shenxing briefly introduced the difficulty of overcoming Bitcoin.

"Isn't that a way to deal with criminals?" Ji Jinyan frowned slightly, feeling fear of Internet technology for the first time.

"At present, the vast majority of countries do not recognize the legitimacy of electronic money, but only recognize blockchain technology. The Internet is a double-edged sword, and it depends on whose hands it is. Ji Shenxing is still very optimistic about blockchain technology, after all, the cooperation with the Beijing police has applied this technology.

Ji Jinyan snorted coldly, "At present, it seems that this knife is in the hands of the enemy in the dark. And we have nothing to fight back. ”
