Stay away from Conan.

"No matter how the criminals used that tape recorder to monitor Mr. Maori or give orders. But as long as it is unlimited communication, whether it is radio, mobile phone signals, satellite signals, or other electromagnetic signals, Everything must be through electromagnetic waves!"

Very firmly, Gao Yuan explained:
"Contact Dr. Ali right away and ask him to monitor all the electromagnetic waves from around Kudo's house, and then find the signal of the so-called radio that Mr. Mori is carrying with him... But, let Dr. Ali pay attention, don't let people find out Already!"

"If Dr. Ali's equipment is used, it should be possible to monitor the signal. However, even if the electromagnetic signal can be monitored, if it is not for the broadcast signal, we will not be able to demodulate and decipher the content?"

Xiao Ai asked suspiciously.

"It's okay, deciphering encrypted signals is something I often do!"

Seriously, Gao Yuan explained:
"As long as you can continue to monitor and collect enough data samples, general deciphering is still very simple!"

"Ok."

Seeing Gao Yuan say so confidently, Xiao Ai waved his hands helplessly, and started calling Dr. A Li, and told Dr. A Li about the current situation and what he hoped Dr. A Li would do.

Immediately, after hearing Xiao Ai's explanation, Dr. Ali, who was not fully awake, immediately agreed, especially when he learned that he would help find the murderer who framed Kogoro Mori, Dr. Ali on the other end of the phone patted Chest guarantees that such things as monitoring signals are covered by him.

In this regard, after finishing all this, after hanging up the phone, Xiao Ai looked at Gao Yuan and said simply:

"All right."

Nodding his head, watching this scene, Gao Yuan thought for a while, and said to Xiao Ai:

"Then... Huiyuan, can I trouble you to get me a laptop?"

Hearing this, she seemed to have expected it a long time ago. With a sigh, Xiao Ai took out her backpack, took out a laptop computer and said:
"I expected that you might need it...Here, take it."

As he said that, Xiao Ai Jiang wanted to hand over the laptop to Gao Yuan, but seeing that Gao Yuan still had drips on his body, Xiao Ai couldn't help saying:
"However, can you look 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... Don't worry, you can operate it yourself and wait for it to be dealt with If you can’t find it, give it to me.”

In this regard, after hearing what Gao Yuan said, Xiao Ai first opened the laptop computer, and helped Gao Yuan complete the link to the main computer and the data connection with Dr. Ali, relying on her own ability, Xiao Ai tried Then began the analysis of those data——

"Hey? Among these signals, there is actually a positioning signal..."

And soon, after trying to analyze the signals sent by Dr. A Li, Xiao Ai first ruled out those signals that could be distinguished and were obviously not abnormal, and found the location in the remaining signal data. the presence of the signal.

Xiao Ai said in surprise.

"Location signal?"

Hearing this, when Xiao Ai mentioned this, Gao Yuan couldn't help thinking:
"That is to say, in the radio that Mr. Maori is carrying, the gangster also specially installed a positioning device? That means..."

"It means that the gangster has been controlling the whereabouts of Mr. Mao Li, and knows where he will go?"

Xiao Ai analyzed this in this way.

"Do not……"

After thinking for a while, Gao Yuan couldn't help but analyze:
"Perhaps the so-called monitoring does not simply monitor the actions of the Maori detective through the function on that radio, but that the gangsters may have been following Mr. Maori all the time, directly observing him like this?
"Because I also thought about it before, but the monitoring of the sound is obviously disadvantageous, and even if the camera is used to shoot secretly, there will be dead spots due to the angle, so compared with this monitoring method to limit Mr. Maori's actions, direct tracking Watching Mr. Maori, and then spying on Mr. Maori in the dark, this may be the most perfect monitoring method! And installing a positioning device is to prevent yourself from chasing Mr. Maori while maintaining the tracking distance."

With that said, Gao Yuan thought for a moment, then asked:

"Try to track where the gangster chose to receive the signal?"

After finishing speaking, Xiao Ai put both hands on the keyboard of the laptop, and was stunned for a while without any operation, then raised his head in doubt, looked at Gao Yuan and asked:

"This... how to track it? This is just a signal from the source that spreads out. How can I know where its receiver is through this source? I haven't deciphered the other signals yet!"

After thinking about it for a while, Xiao Ai couldn't think of a way to solve this problem.

"Didn't you say that? The gangster located Mr. Maori most likely to be able to directly track Mr. Maori and observe him near him. If so, now that Mr. Maori is hiding in Kudo's house, the gangster's current location may also be near there." ...Then, let's try to look around Kudo's house, is there anything suspicious right now?"

Gao Yuan said:
"As for deciphering the signal, it is not difficult. It is nothing more than finding out the coding rules of the analog signal and the communication protocol used to decipher the analog signal after the electrical signal is converted into an analog signal. Generally speaking, no one will use their own coding rules and The communication protocols are all ready-made, so it is easy to crack them by comparing a few."

In this regard, listening to Gao Yuan's words, Xiao Ai tried to operate, and then said first:

"On the nearby monitoring screen, no other suspicious figures were found..."

After speaking, Xiao Ai continued to operate, and then seemed to have made obvious progress, and said in surprise:
"Hey? It's really that simple? Can it be deciphered like this? Then..."

Muttering to himself, it seems that there is no need for Gao Yuan to say anything. With the current situation, Xiao Ai contacted Dr. A Li, and began to try to connect to the other party's communication——

"The other party is using a mobile phone to communicate, and is listening to the voice of Maori Detective in real time! In this case, it is easy to track the other side's position in reverse..."

After finding the most critical signal, Xiao Ai quickly traced back to the source of the target signal, and then couldn't help saying:

"Found it! It's not far from Maori Detective...but the signal source is moving!"

"Moving signal source? The gangster has been moving?"

Hearing the result of Xiao Ai's inquiry, Gao Yuan thought silently——

If the gangster is moving, where should Feiyingli's whereabouts be?Could it be that he was also being moved by the gangsters?Or was he locked up somewhere alone? (end of this chapter)
