But just because the helicopter is invisible, time regression has no use, which is very embarrassing.

The so-called time review is to replay the scene at that time in Mu Yuan's mind, but it does not really put Mu Yuan in the environment at that time.

In other words, what he saw was only an image and did not actually exist.

Therefore, when the helicopter was directly out of sight, Xiaomao was unable to do anything despite all his abilities.

Although there is still sound when the helicopter is flying, how can it be intuitive to the naked eye to use the strength of the sound to identify the location of the helicopter?

Without knowing how far the helicopter would fly, Mu Yuan didn't want to waste too much chivalry points.

He planned to think of a solution first.

The data analysis and collection instrument is now Mu Yuan's main reliance.

He speculated that no matter how powerful the group behind the scenes was, as long as they were still people on Earth, they would be unlikely to develop a global communications system.

Well, Mu Yuan admitted that this organization might have its own communication system and just put a few satellites into the sky. It would not be difficult for some big chaebols.

But even if the organization has such a communication system, it is impossible for people in the organization to only use this communication system.

In the final analysis, this organization is definitely only a small-scale organization, and the people inside cannot be disconnected from society and must be connected.

To communicate with people outside, it is impossible to use communication tools.

This is the breakthrough.

It was also based on this that he asked Lars to retrieve the data before.

It's just that he asked Lars to adjust the data to deceive others. The data that the other party could obtain was definitely not as comprehensive as what he had found.

The key is that once the data is obtained, it is very troublesome to analyze it.

"Query all communication data, location XXX, time point is August 21 last year..."

Mu Yuan named more than seventy times and places in succession, including the dumping points and estimated times of all cases.

If you go to the local communications company to check this data, you have to go from store to store, and it may not even be fully covered, such as satellite phones.

But Mu Yuan's use of data analysis and collection equipment is completely like Juehu.com, not even letting go of any clues.

The data queried in this way is massive!

Although Mu Yuan was mentally prepared for this, he was still shocked when the data was actually put in front of him.

Nearly 100 million pieces of data!

Calculated on average, the data involved in each case is in the millions.

This is actually normal, after all, Mu Yuancha's time span and location range are slightly wider.

"Compare those with common feature values ​​and screen for targets that appear in two or more locations."

The next second, the results appeared, more than 150,000.

"Aren't these guys so good at running away? Are you going to die if you don't travel around for a day?"

Although this number is significantly higher than nearly 100 million, 150,000 is still an amount of data that cannot be analyzed and judged manually.

"Screen for targets that appear in three or more locations."

This time the data feedback is much simpler, with only more than 3,000 pieces left.

This amount of data can be used for some analysis, at least for Mu Yuan.

He tried to click on it and looked at it. The more than 3,000 items listed basically belonged to countries where many similar cases had occurred.

"Fortunately, it seems that there are still a small number of people traveling across borders."

Mu Yuan didn't plan to read them all...

"Screen for targets that appear in four or more locations."

"Group thirty-five?"

Mu Yuan was overjoyed. If his previous inferences were correct, then the answer should be in these thirty-five pieces of data.

However, Mu Yuan did not dare to rule out that those people did not use other communication tools when moving. In this case, no matter how much he screened, it would not work.

Opening these thirty-five sets of data, Mu Yuan looked at them one by one.
Chapter completed!
