Siheyuan: I eat melons while doing scientific research

Chapter 1312 Showing off one's skills in front of Guan Yu (4k)

Those familiar with this type of work know that the most dangerous place is the safest place, and things like being under a bright light are mostly unrealistic. They require an extreme coincidence of environment and circumstances, or a last resort.

Normally, no one would willingly walk a tightrope to do this kind of thing.

Therefore, it's impossible for the signal to come from No. 95 Nanluoguxiang. Besides, there are quite a few people there. To hide it from them, the people and equipment would have to be invisible.

"Don't worry, according to the discoverer's estimate, this signal should have been triggered by equipment at No. 95 Nanluoguxiang, but the signal transmission point is not there," said a comrade on the work vehicle. As for the principle behind it, that's another matter, and there's no need to worry about that now.

“Hmm, let’s keep turning! The one transmitting the signal should be a directional antenna. In any case, it should be around here!” another comrade said.

The discoverer is truly remarkable! He predicted long ago that the excitation signal could be omnidirectional, misleading radio signal locating equipment. I wonder where this senior researcher came from; truly impressive!

He is a senior, but not old, and he's not in this line of work. After all, Gao Zhendong has been in the military for over ten years, so calling him their senior isn't an exaggeration.

The car continued to move forward, and at least one thing was encouraging: the frequency of the signal was being closely monitored. As soon as the other side changed its frequency, the equipment here immediately switched to the new frequency.

"We're here! Southwest! Stop the car!" An excited voice suddenly came from one of the cars.

If the other side has a directional antenna, then you can't go any further, or you might lose the signal.

"That's right, it's in this direction!" The comrade in the car looked at the direction finding results and confirmed that No. 95 Nanluoguxiang was indeed in this direction. This meant that the transmission point of the signal, the radio work vehicle, and No. 95 were roughly in a straight line. There was no doubt about it!
"I've got his direction! Walk another 100 meters. Yes, we'll use beamwidth to roughly pinpoint his location!"

Furthermore, directional antennas also have a limited beamwidth, which makes it possible to locate the two vehicles, unless they are using lasers. However, laser eavesdropping has long been cracked in China, and the adversary cannot possibly be unaware of this.

A minute later, the comrade in the work vehicle grabbed the radio microphone: "Found it, probably near No. XX, XX Alley!"

This time, they notified not one of their two work vehicles, but another team that was already prepared.

When the team arrived near the area located by the radio work vehicle, they scanned the surroundings and, without even using the signal strength display device, the team leader quickly pinpointed a spot: "That's it! Let's go, let's sneak over there!"

Although the colleague on the radio work vehicle said that there was some error in positioning, he didn't care about the error because he had work experience. Advanced equipment is good, but problems that advanced equipment can't solve may be solvable with work experience.

Relying on advanced technology and depending on advanced technology are two different things.

This place is located high up, with few lights, and even on hot days, the windows are tightly closed, making it seem so out of place with everything around it.

Normally, it might be that no one lives there or that the person has gone out, but under these special circumstances, the house is as obvious as a louse on a bald man's head.

The person inside the house was unaware of all this; he was simply diligently carrying out his work. The workload wasn't heavy; he just needed to keep the equipment running. Any data collected would be automatically recorded. His only job was to ensure the equipment was functioning properly.

If it weren't for the possibility of losing one's head, this could even be considered a cushy job, the kind where you can eat pickled vegetables and tofu while working and even have a couple of drinks.

For him, the time from when the target person gets off work until they leave home is his working time, which is like working the night shift.

He took a sip of wine with relish, as if trying to use the alcohol to suppress his fear of the mission.

Just then, something rolled in under the door with a clatter.

The man was so frightened that his soul almost left his body. He turned around and rolled to a corner behind the bed, grabbing a gun in his hand.

Regardless of what rolled in, he realized he would have to fight desperately soon, or he had another option: to surrender.

Should we vote or not?

However, reality did not give him a choice. Just as the thought crossed his mind, a loud bang and a bright flash engulfed him.

Flashbang grenades are incredibly useful against unsuspecting people!
He suddenly lost all consciousness. When he regained a little self-awareness amidst the dizzying sensation, he found himself covered in sweat and pinned to the floor.

"Caught!"

"Let's see if there are any other options nearby."

"there is none left!"

"Notify the comrades in the surrounding area not to let their guard down!"

"Yes!"

The man and all the items in the room were quickly loaded into the car and taken to where he was supposed to go.

Not long after, Gao Zhendong was taken to a subordinate unit of the National Defense Industry Committee. Beside him were comrades from the National Defense Industry Committee in charge of related work, as well as leaders from the National Defense Industry Committee who had just finished get off work and rushed back.

Before them was the wooden carving that someone else had given to Lou Xiao'e.

"Golden-lipped eavesdropping device... I didn't expect they were still using this trick, and they've even improved it!" A colleague from a relevant unit exclaimed as he looked at the device.

The Golden Lip Eavesdropping Device, a brilliant idea conceived during the conflict between the White Bear and the United States, was a major embarrassment for the Americans. Lubyanka had hidden it inside a wooden carving of the American coat of arms, and brazenly presented it as a gift from the Vanguard to the American embassy in the White Bear. The fact that it was a gift from the Vanguard was why Gao Zhendong suddenly remembered this incident after seeing the Banggeng siblings wearing red scarves.

The Citizens couldn't find anything wrong with it and happily hung it in the ambassador's office, where it remained for seven or eight years.

As for its discovery, there are rumors that it was found by Citibank's own Langley Center, while others say it was discovered by people on Westminster Avenue in John Bull's town. At the time, John Bull's people were eavesdropping on the White Bear's people and accidentally overheard the signal emitted by the bugging device.

However, why the people from John Bull would come to the vicinity of the Citizens' embassy in Washington to eavesdrop on Washington remains unknown. It's a matter of father and son, after all; it doesn't matter, nothing else matters.

At that moment, the comrade in charge of the relevant work was pointing to the spot where Gao Zhendong had noticed something amiss: the round, golden sun at the center of the wood carving.

This thing is empty! It's like a microphone; the metal diaphragm on the front vibrates as you speak.

This vibration causes a metal needle, symbolizing sunlight, to vibrate below, which acts as a primitive vibration signal amplifier.

The most ingenious part is that this thing does not need any power supply, because its energy comes from the excitation of electromagnetic waves injected from the outside. This vibration, amplified by the metal needle, will modulate the incident electromagnetic waves. Then, by using a receiving device outside to receive these modulated electromagnetic waves, the sound inside the room can be reproduced.

It is a brilliant idea, similar to laser eavesdropping, but unlike lasers, it does not require a vibrating surface or a line of sight to the target, because electromagnetic waves have much better penetrating power than lasers!

No wonder even such an important location as the Citibank Embassy was kept in the dark for seven or eight years, causing the Langley Center to lose face. This facility is indeed quite impressive.

And now, similar equipment has appeared before our comrades.

"I never expected them to do the opposite, directly embedding the device itself on the surface of the cover. Whoever did this has some psychological savvy! And the design is ingenious, making perfect use of the shape of the wood carving." Even our own comrades, let alone others, showed respect to such a clever opponent; at least they managed to get the device in despite the tight security!

I just didn't expect that the person being eavesdropped on would be identified so easily.

It's still uncertain where this thing was placed. Although Lubyanka was the founder of the Golden Lip Eavesdropping Device, once the technology was made public, anyone could make it. The device is just cleverly conceived, but it's not technically difficult.

Gao Zhendong laughed and said, "I only became suspicious because I noticed that although there were many metal needles representing sunlight in this sculpture, there was only one metal needle that was rigidly connected to the metal membrane box and could vibrate freely."

At the same time, there should not be too many vibrating metal needles, because the signals from different metal needles will interfere with each other.

The quacking of a single duck might evoke a sense of pastoral beauty, but the quacking of a flock of ducks together can only be irritating.

Gao Zhendong's words made the leaders present laugh, as if his opponent was showing off his skills in front of Guan Yu.

Who is Gao Zhendong? He is extremely knowledgeable about radio frequency equipment, and is also a master in encryption, eavesdropping, and other related work and technologies. He is also very sensitive; the last laser eavesdropping device was brought down by him.

You just blatantly put such an obvious eavesdropping device in front of him, aren't you just asking for trouble?

"Comrade Zhendong, it's still our fault for not doing our job well, which put you in danger." The comrades from the relevant units felt very guilty.

Gao Zhendong laughed: "That's not how it is. This thing is not dangerous, so I was able to get away with it. If I had to say, the most careless one would probably be my wife."

He was telling the truth. If it were truly dangerous, it would never have escaped the keen eyes of the relevant authorities. This thing was only able to sneak into the country through such open channels and eventually end up in Lou Xiao'e's hands because it was cleverly disguised and posed no danger whatsoever.

"This has nothing to do with Comrade Lou Xiao'e; it's because we haven't done our job well."

The leaders of the National Defense Commission laughed when they saw this: "Alright, alright, what's the big deal? It seems the other side still has some sense of propriety; they only want the eggs, not the hen that lays them..." In fact, everyone knew which side was responsible for this, their style was very clear, and they were quite restrained in their actions.

At this point, he remembered something important: "Have you investigated the person who sent this?"

"An investigation was conducted, and based on the results, it's unlikely she actively participated in this matter. According to her, the metal disc representing the sun in the center of the sculpture was originally solid, not a hollow membrane box like this. As a foreigner studying here, she has some friends who are also from abroad. Now, the investigation reveals that some of them have a connection to Lubyanka."

"How...how did the other party know that she was going to give a souvenir to Comrade Lou Xiao'e?" This is a problem. It is impossible for the other party to have foreseen the future and target this person at the right time.

"They mentioned it during their casual conversations. The notice about Comrade Lou Xiao'e's return to school for a lecture was released quite early by the Second Affiliated Hospital of Beijing Medical University. After hearing the notice, she had this idea and discussed it with other international students. The young girl really admires Comrade Xiao'e. Moreover, after that, she stayed in the hospital for a day because she was feeling unwell."

"Ha, Lubyanka's 'comrades,' your work is still so meticulous." The leader of the Defense Industry Committee laughed in exasperation upon hearing this.

"Furthermore, the tests conducted by comrades from the 17th Ministry of Machine Building showed that the material and wear of this pickup diaphragm and vibrating needle are different from the other needles. It is estimated that it is already difficult for them to make this set of equipment in such a short time. They do not have the ability to replace all the needles, and it would be easy to be discovered."

"Hmm...it seems that's the case."

"There's another situation. When we verified the information with this student, we learned that her gift had put Comrade Lou Xiao'e in danger. This student showed an extremely strong sense of guilt, and even... even a slight tendency toward suicide. Unless she's a seasoned veteran or a genius in this field, it's very difficult for a girl under twenty to fool us in this regard."

People from a tribe on a distant continent have different ideas from us, and we can't guess how they will react. But we can tell whether their reactions are genuine or not.

The leader of the Defense Committee nodded: "Hmm, it seems Comrade Xiao'e brought them a lot of things. Well, whether it's true or not, there's no point in dwelling on a young girl. Let's leave this line as it is." Besides, even in the worst-case scenario, what's exposed is much easier to deal with than what's hidden. It's just that she definitely won't have the chance to contact Lou Xiao'e again in the future.

Upon hearing this, Gao Zhendong laughed: "Comrade, could you please tell this young lady for me if you could get a real one?"

This left everyone else present speechless.
