Xiaoya and the others quickly walked out of Yu Jing's study, then carefully closed the door and followed Wan Lin to the side room where Xiaoya and the others were resting.
Wan Lin walked into the room, closed the door and whispered: "Did you see that black spot? That should be the anomaly that Xiaobai discovered last night. No one approached the back of the building last night, but that little thing just now
Suddenly it flew and stuck to the glass. Xiaobai must have heard a strange noise at that time, so he quickly got up and ran out to check."
Xiaoya and the two also suddenly realized at this time, Wan Lin continued: "That thing should be a miniature eavesdropping device. Doesn't Mr. Yu have the habit of working at night?"
Xiaoya immediately replied: "Yes, Mr. Yu sometimes works late in the study. He also uses his evening time to contact some famous international physicists to discuss some research issues together, all in foreign languages.
of."
Wan Lin nodded and said, "That's right. That bug should be used to listen to Mr. Yu's voice at work and to obtain some information from it."
Xiaoya opened her eyes wide in surprise and whispered: "That bug can detect the sounds inside the house outside the glass?"
Lingling stared out the window and replied: "That is an eavesdropping device that uses the principle of sound wave vibration. When we talk in the house, the sound waves emitted will definitely cause the window glass to vibrate, and the other party uses this vibration principle.
, using extremely sensitive remote monitoring equipment outside, the frequency of the glass vibration sent back by the bug is received, and then restored to the sound of our voices."
After Lingling finished speaking, she bent down and took out a telescope from her backpack and walked to the window. She raised it and carefully observed the tall building outside the courtyard wall. She pondered for a while and said: "It seems that the other party should be in the building opposite."
This eavesdropping device was launched from the building. But this place is at least more than a thousand meters away from that building. How did they launch it?"
Wan Lin raised his eyes to look at the tall building opposite, a cold light suddenly appeared in his eyes, and whispered: "The military compound is heavily guarded, and there are many surveillance cameras on the outer wall. It is impossible for the other party to get close to the military compound.
It is an important military area. Therefore, their only option is to use the tall building outside the compound and monitor the movements here from a high position."
As he spoke, he raised his hand to take the telescope from Lingling, carefully observed the building in the distance, then raised his hand to point to the rows of windows on the opposite building and said: "Judging from the strict security situation in the military compound, it is impossible for the other party to
Get close to here and place this bug. It seems that the opponent has a skilled sniper."
As he spoke, he raised his right hand and extended his thumb, gestured towards the window in the distance, and continued with a gloomy face: "It seems that the other party used a long-range sniper rifle to shoot the bug at the window of Mr. Yu's study.
The opponent's sniper bullets must have been modified. Not only was the eavesdropping device mounted on the warhead using special materials, but the amount of gunpowder in the cartridge case was also controlled very accurately. The eavesdropping device exhausted its kinetic energy just as it landed on the window.
It won't break the glass, and it won't make too much noise. From this, it seems that the other party is indeed an expert with guns."
When Xiaoya and Lingling heard Wan Lin's analysis, their faces became a little nervous. Xiaoya said in a low voice: "Fortunately, the other party is not plotting to assassinate Mr. Yu, otherwise it would be really difficult to deal with such a gunman among his opponents."
Wan Lin and Lingling looked at the tall buildings in the distance and nodded. Now the other party is in the dark. If the purpose of the other party is to assassinate Yu Jing, this kind of sniper who can snipe at ultra-long distances is indeed very powerful.
Difficult to prevent.
Lingling pondered for a moment, stared out the window and whispered: "The other party uses such a small eavesdropper. The signal transmission range of the eavesdropper must be limited. The other party must have a receiving point in the high-rise building opposite. I use electronic countermeasures
Use the box to determine the opponent's position." She is a master in electronic countermeasures, so she naturally knows the operating mechanism of this small listening device.
As she spoke, she turned and walked to a single bed next to her, bent over and pulled out her electronic countermeasures box from under the bed, and then placed the countermeasures box on the small table next to the window.
Xiaoya asked worriedly: "If you determine the opponent's position now, will it alert the opponent?" Lingling opened the cover of the confrontation box and replied in a low voice: "No, I will not interfere with the opponent's transmission frequency, so they
You won’t notice.”
Lingling's eyes were fixed on the screen on the electronic countermeasures box, and she slowly twisted a knob with her right hand. A layer of frost had already appeared on her pretty face. As she stared at the curve on the screen, she sneered: "
You are playing with electronic gadgets with us, and you are seeking death!"
Xiaoya and Wan Lin looked at each other, with smiles on their faces. Indeed, conducting surveillance under the nose of Lingling, an expert in electronic countermeasures, is indeed asking for death.
Soon, Lingling put on the earphones, pointed the electronic countermeasures box at the high-rise building in the distance, and quickly pressed a shooting button. She then called up the picture of the building and quickly superimposed it onto an image showing the electronic curve.
From the back, she stared at the screen intently for a while, then raised her head and looked at Wan Lin and said, "I'm sure, the receiving source of the monitoring signal is in the room with the sixteenth window on the sixteenth floor."
Wan Lin and Xiaoya looked up and stared at the window in the distance. Xiaoya whispered worriedly, "The other party won't see us, right?" Lingling smiled.
He replied: "No, the house is dark during the day, the other party can't see us, and we can't see what's going on inside their house either."
After Lingling finished speaking, a murderous look suddenly appeared in her eyes, and she whispered to Wan Lin: "Baotou, should we go over and kill these people now?"
Wan Lin shook his head thoughtfully, and then said: "We must be cautious about this matter. Let's go back to Li Tou to discuss this clue. This clue must be discussed with Deputy Director Wang Molin and others before we can formulate an action plan. Since the other party is for monitoring, temporarily
We won’t leave yet, let’s not act without authorization.”
After he finished speaking, he looked at Lingling and asked: "Technically, can you block the other party's listening signal without arousing the opponent's suspicion?"
Lingling hesitated and replied: "Shielding is very simple, but once it is blocked, the other party will not be able to receive the radio signal from the eavesdropper, so they must be alert. Therefore, we cannot block the other party's signal unless it is absolutely necessary."
Wan Lin nodded and said: "Let's go, let's go to the Operation Department to report to Li Tou first, and let him discuss with Deputy Director Wang before making a decision. When you see Mr. Yu, remind her that she must speak at home.
