Mingzhu City National Security Bureau.

In the technology center, Shu Huimin and Li Shuangkui are doing intense analysis work. Gao Ge and Lu Wei followed Yamamoto around the clock with the National Security Action Team. The four of them take turns to combine and participate in various actions. Li Shuangkui's logical analysis ability is strong, so he eased up and partnered with Shu Huimin for data analysis.

Yamamoto paid the fine, called a local businessman to vouch for it, and was released on bail that night. Subsequently, the task force carried out the following actions according to the plan and carried out all-weather tracking and monitoring of him.

At present, the work of Shu Huimin and Li Shuangkui is the most important work of the entire task force at present, and there are several national security technicians working with them.

The main object of analysis is the destroyed mobile phone.

Figuring out what messages are being sent from the phone at the last minute and where it is being sent is the most important clue. Therefore, the eyes of the entire task force were on Shu Huimin and them.

With the confessions of Zhang Lei and Sally, Yamamoto can be arrested, but the evidence is still insufficient. Only by finding accurate evidence of Yamamoto's espionage activities can he be completely controlled. What's more, the above wants to catch more big fish through Yamamoto.

The power of the self-destruct device is not small, and the mobile phone is basically out of shape. It took three days for the technicians to put it together, and then another three days to make a full repair before it reached the standard that could be detected and analyzed.

The structure of the phone is not complicated, but because of the severe damage, it is difficult to find any clues unless you go back in time.

Shu Huimin is in charge of this seemingly impossible job.

Li Shuangkui was faced with an even larger workload - he had to analyze a large number of wireless signals sent from the hotel at that time of the day. He was helped by a telecommunications technician from Guoan, who was responsible for communicating and coordinating with local telecommunications companies at all times.

Specific to the wireless signal sent out within the hotel, it seems that the range is not large, but you must know that the area where the hotel is located is the most prosperous area, and it is the most frequent time period of radio wave activity at night, and in addition to the civilian category, other special frequencies must also be investigated.

The key is that Li Shuangkui's only basis is only one - the specific time when Yamamoto's mobile phone sent out the signal.

At this point in time, he found a total of more than 10,130 signals. One by one, he had to check where the signals ended up being transmitted to eliminate them. Because it is in the past tense, there is no way to decipher the signal.

This work is definitely not easier than Shu Huimin's.

After working continuously for another three days and three nights, in the early morning of the fourth day, Shu Huimin slowly stood up from her position. The monitor she uses stays on one page, and she stares at it.

"Da Kui, come and take a look. ”

Li Shuangkui hurriedly came over when he heard this, and looked at it fixedly, "Completely different signal characteristics, you wait!"

As if he had been suddenly injected with hormones, he quickly returned to his position, and his fingers tapped on the keyboard. Shu Huimin walked over and stood behind her and stared.

Breakthrough progress.

Shu Huimin found a clue from her mobile phone - the characteristics of the signal sent out during that time period.

In other words, her discovery provided an important filter for Li Shuangkui!

A few minutes later, Li Shuangkui hit the enter key heavily, and the data on the screen flowed quickly and then stopped.

"Found it!" Li Shuangkui said in surprise.

Everyone else gathered around, very excited. After nearly ten days and ten nights of continuous rotation, all the masters in the bureau have been concentrated, and they finally have eyebrows.

"Now start tracking along the trajectory. As long as I can determine which signal it is at the time, I can find out its final destination. Radio waves are not untraceable, even if much longer has passed. Because radio waves cannot move on their own, they need various carriers and transceivers. ”

Li Shuangkui explained to everyone in a deep voice while being busy quickly, but subconsciously, who is not a master of these people around him, how can he not understand these simple truths.

"Found it. A few minutes later, Li Shuangkui stopped.

It is not easy to do this, and it requires the mobilization of a lot of resources and the support of strong information analysis capabilities.

Shu Huimin glanced at it, frowned, and said, "Guangzhou, the destination will be this place?"

"Is there any problem?" said Li Shuangkui.

Shu Huimin shook her head and said, "I don't think it's that simple. Check it out and see if Guangzhou is playing a role as a relay. ”

Frowning and jumping, Li Shuangkui moved quickly, and it was soon clear.

"It's cunning, it's a relay point. Li Shuangkui drew inferences from one another and continued to move, "Let me see how many circles you have to go around." ”

To their surprise, after almost an hour of busyness, Li Shuangkui followed the signal all the way, first to Hong Kong, then to Singapore, and finally from Singapore to Riyadh.

Everyone looked at each other, and they couldn't imagine that a small signal sent by Yamamoto's mobile phone was actually transferred to the Middle East after several relays!

It's not at all expected, and it's very illogical.

How could a foreign spy who was a Japanese businessman have connections across a third of the globe to the Middle East?

In fact, the clues of the case have gone far beyond the responsibility of the Jinling Provincial Bureau.

Shu Huimin was very calm, she actually said to Li Shuangkui, "Continue to check, you must determine where the terminal where the signal is finally received!"

She actually suspected that Riyadh was not the final destination either!

Li Shuangkui cheered up, sweat began to appear on his forehead, and continued to investigate.

After almost an hour passed, Li Shuangkui knocked down the keyboard with some weakness, and said in a tone that he couldn't believe himself, "South of Damascus, I took a peek and took a look, it is the area controlled by the DIS forces. ”

Shu Huimin fell into deep thought.

At first, they judged that there were two possibilities for the information sent by Yamamoto before his arrest, either it was important information, or it was a notification to go online or evacuate. The entire espionage activity, no matter how much imagination is used, cannot be related to the withdrawal of DIS forces thousands of kilometers away.

The facts are in front of us, and these young people are helpless.

At the moment, Yamamoto does not know that the police have arranged his arrest by the security services, and he is still active. This shows that the message sent is not a notification to the upline or downline to evacuate, because he doesn't think he's been exposed. Then there was only one possibility left - important information, and in the case of uncertainty about whether he was exposed, Yamamoto took the safest way - to send the information out first.

"Can you decipher the content of the message?" Shu Huimin asked, and after asking, she knew that she had asked more.

Li Shuangkui shook his head, "There is no way." The information is specially encoded, and unless we ask Yamamoto to tell the pattern and meaning, we can't do anything about it. ”

Taking a deep breath, Shu Huimin said, "After summarizing the clues, report to the top, the development of the case has exceeded our understanding." ”

The crowd began to get busy, sorting out all the clues, and then putting them together.
