A private jet exploded and smoked, and security at McCarran International Airport was immediately activated. Parts of the area were cordoned off, and firefighters and security personnel were quickly dispatched. Lin Rui and the others were almost blocked in the airport, and finally managed to avoid airport security before they got out and returned to the safe house in Las Vegas.

"Damn, I almost caught that guy. Sergei said with some annoyance. "This Liszt is really a slippery head, and he escaped at a critical moment. And even those materials were taken away. ”

"Don't regret it. Shogishi whispered, "We may all have been fooled." ”

"What's wrong?" Lin Rui frowned.

"The information on Pandora's plan may not have been in the suitcase that Liszt had with him. Jiang Jian said in a low voice.

Lin Rui was a little surprised and said, "What's going on?, how do you know?!"

"I couldn't figure it out when I got back, so I asked Cobain to steal the surveillance footage from the airport's information center. They had checked the box when they went through security, and it contained only a few newspapers. Jiang Jian said in a low voice.

"How is this possible?" Sergey frowned, "Could that box of newspapers at the security check be just a cover for them to sneak in, and then change the real thing in through the bag?"

"It could be that, but it's also possible, it's just a temptation. If we catch Liszt, but we can't find the documents of Pandora's plan. There is no way to take him. The real documents must be hidden somewhere. Shogishi whispered, "I think it's very possible." With their shrewdness, they don't go around with things. ”

Lin Rui was also silent. He turned around and said, "Play their surveillance video a few more times, there must be something in it that we overlooked." ”

Shokishi nodded, repeating the video back and forth on the display.

Lin Rui watched it at least ten times, watching these people walk back and forth on the screen. He seemed to remember something, patted Jiang An's shoulder and said, "Can the picture still be enlarged?"

Shogishi nodded, "But magnifying the clarity may not be enough." After the picture was enlarged, Lin Rui saw a sudden whisper somewhere, "Stop, do you see that their mouths are moving, as if they are talking to themselves?"

"Definitely. Shogishi frowned. "In order to avoid acting at the same time to attract the attention of others, the time for them to enter the airport was nearly thirty minutes before and after. Perhaps they were communicating with each other, otherwise they could not have acted in such a consistent manner. ”

"But, if you look at the screen, they're not wearing communicators, they're not wearing wireless headphones. Lin Rui said in a low voice.

"Maybe they wore it, but we didn't feel it. Shogan hesitated.

Crystal thought for a moment and immediately said, "I thought of something. ”

"What did you think of?" Lin Rui frowned.

"Their equipment. These men, including Liszt, had worked as spies in the intelligence services. Crystal thought for a moment, "Because of their special work, maybe their communication tools are very advanced and hidden. ”

"What do you want to say, is it possible that the Americans have reached such a point in technology? They have not only studied genetic technology, but also understood communication devices that can be invisible?" Sergei scoffed.

Crystal ignored his taunts and said slowly, "The CIA has a research department, and this department specializes in manufacturing special espionage equipment for them. The research department used to be a very important department within the CIA, and it used to provide a lot of wonderful spy equipment for cIa's agents. They even launched bionic drones for eavesdropping as early as the 7o years of the last century.

One of these technologies is called stealth communication technology, which can replace ordinary communicator technology by implanting a tiny chip in the jawbone. ”

"Implantation of a chip in the jawbone will allow communication?" Sergey said in amazement.

"Yes, it's called bone conduction. Strictly speaking, it's not a very new technology, it's just not easy to notice. Sound can be received not only through the eardrum, but also through the skull and jaw to the auditory nerve, causing hearing.

In science, this conduction of sound is called bone conduction. Some people who have lost their sense of hearing can use bone conduction to hear sounds. It is said that when the musician Beethoven became deaf, he bit one end of the stick with his teeth and put the other end on the piano to listen to the sound of his own music, so as to continue his creation.

Therefore, at that time, some people proposed a wireless communication design scheme designed with this idea in mind. Modern chip technology is already nanoscale, and it is effortless to make this happen. This stealth communication device allows spies under surveillance to communicate with others without anyone noticing. But as I recall, this scheme was not adopted. The man who proposed this plan was not reused and left the CIA. Crystal frowned.

"If you look at this surveillance video, they're muttering to themselves, they should be talking with this hidden spy communicator. Jiang Jian said in a low voice.

"Great, it looks like another cIa departing agent. Sergei shook his head.

"If they're really using that kind of technology, then there's a good chance that this person is also their backup, or at least provides them with the technical equipment. Lin Rui turned around and said, "Find out this person immediately." I want to know where this person is and what he's doing. ”

Crystal nodded, and turned away. It was about half an hour before she returned. "Rick, your guess should be right. This man was a radio amateur, and people who knew him called him Squirrel. And he's in Las Vegas at the moment, and he's settled here. Squirrel opened a thrift store in the city, buying and selling second-hand stereos and some second-hand communication equipment.

I looked into it and he had purchased some microchips and parts in recent months. In this way, it is very likely that the bone conduction communicator used by Liszt and them came from him. ”

Lin Rui paced back and forth, "Liszt has become a frightened bird at the moment, and he won't trust anyone else, so it's very likely that he is hiding in the gray squirrel." A thrift store should generally be visited by very few people. Should be a good hiding place. Moreover, even if Liszt was not there, the gray squirrel might have known information about Liszt. ”

"Liszt escaped with the documents of Pandora's plan, and if it drags on for longer, the more unfavorable it will be for us, so when will we start moving?"

Lin Rui looked at the team members and said, "Act immediately." We have to find this squirrel and be prepared, Liszt may be there. ”
