"No matter how the gangster used the tape recorder to monitor Mr. Maori or issue orders. But as long as it is unlimited communication, whether it is broadcast, mobile phone signal, satellite signal, or other electromagnetic signal, All must be through electromagnetic waves!”
Very confidently, Gao Yuan explained:
"Immediately contact Dr. Agasa and ask him to monitor all the electromagnetic waves emitted around Kudo's house, and then find the signal of the so-called radio that Mr. Mori carries with him... However, Dr. Agasa must be careful not to let anyone discover it. Got it!"
"If we use Dr. Ali's equipment, it should be possible to monitor the signal. However, even if we can monitor the electromagnetic signal, if it is not a broadcast signal, we cannot demodulate and decipher the content, right?"
Xiao Ai asked doubtfully.
"It's okay, deciphering encrypted signals is something I often do!"
Seriously, Gao Yuan explained:
"As long as we can continue to monitor and collect enough data samples, general deciphering is still very simple!"
"All right."
Seeing Gao Yuan speaking so confidently, Xiao Ai waved her hands helplessly, and started to dial Dr. A Li's phone number, telling Dr. A Li the current situation and what she hoped Dr. A Li would do.
Immediately, after hearing Xiao Ai's explanation, Dr. Agasa, who had not yet fully woken up, immediately agreed, especially when he learned that he would help find the murderer who framed Mouri Kogoro. Dr. Agasa on the other end of the phone was filming Chest promised that the matter of monitoring signals would be taken care of by him.
In this regard, after finishing this, Xiao Ai hung up the phone, looked at Gao Yuan and said simply:
"alright."
Gao Yuan nodded and looked at this scene, then thought about it and said to Xiao Ai:
"So... Haiyuan, could you please get me a laptop?"
Hearing this, as if he had expected it, Xiao Ai sighed and took out his backpack, took out a laptop and said:
"I thought you might need it...here, take it."
As he said that, he saw Xiao Ai trying to hand the laptop to Gao Yuan, but seeing that Gao Yuan was still dripping with blood, Xiao Ai couldn't help but say:
"But, is it okay for you to be like this?"
"Um……"
Looking at Xiao Ai's gaze, Gao Yuan also looked at his current situation, and then said:
"It's nothing serious. It doesn't matter. Just connect to the main computer and let Dr. Ali transmit the data he monitored. The specific operation is not difficult... If you are really worried, you can do it yourself and see if it is dealt with. If you can’t find a place, just give it to me.”
In this regard, after listening to Gao Yuan's statement, Xiao Ai first opened the laptop and helped Gao Yuan complete the link to the main computer and the connection with Dr. A Li's data. Relying on his own ability, Xiao Ai tried Then began the analysis of those data——
"Huh? Among these signals, there are actually positioning signals..."
And soon, after trying to analyze the signals sent by Dr. Ali, Xiao Ai first eliminated those signals that could be distinguished and were obviously not abnormal, and then found the positioning in the remaining signal data. signal exists.
Xiao Ai couldn't help but said in surprise.
"Location signal?"
Hearing this, Gao Yuan couldn't help but think thoughtfully when Xiao Ai mentioned this:
"In other words, the gangster specially installed a positioning device on the radio that Mr. Maori carried with him? That means..."
"It means that the gangster has always been in control of Mr. Maori's whereabouts and knows where he will go?"
Xiao Ai analyzed this.
"No……"
After thinking for a moment, Gao Yuan couldn't help but analyze:
"Perhaps the so-called monitoring is not simply monitoring the actions of Detective Maori through the function on the radio, but the gangster may have been following Mr. Maori and directly observing him like this?
"Because I have thought about it before, just sound monitoring has obvious disadvantages, and even if you use a camera to shoot secretly, there will be blind spots due to the angle, so instead of restricting Mr. Mori's actions through this surveillance method, it is better to directly track Watching Mr. Maori, and then monitoring Mr. Maori in the dark, this may be the most perfect monitoring method! The purpose of installing the positioning device is to prevent yourself from chasing Mr. Maori while maintaining the tracking distance."
With that said, Gao Yuan thought for a moment, and then asked:
"Try to track where the gangster chose to receive the signal?"
After saying that, Xiao Ai put his hands on the keyboard of the laptop. He was stunned for a while without any operation. Then he raised his head in confusion, looked at Gao Yuan and asked:
"How... how to track this? This is just a spreading source signal. How can I know where its receiver is through this signal source? I haven't deciphered the other signals yet!"
After thinking seriously for a moment, Xiao Ai couldn't think of a way to solve this problem.
"Didn't I say that? The gangster located Mr. Maori most likely to be able to directly track Mr. Maori and observe him near him. So if that's the case, now that Mr. Maori is hiding in Kudo's house, then the gangster's current location may also be nearby. ...Then, let’s try to look around Kudo’s house. Is there anything suspicious at the moment?”
Gao Yuan said:
"As for deciphering the signal, it is not difficult. It is nothing more than converting the electrical signal into an analog signal, finding out the encoding rules of the analog signal and the communication protocol used, and reverse deciphering. Generally speaking, no one will use personal encoding rules and The communication protocols are all ready-made, so it can be easily cracked by comparing a few."
