It can be analyzed that this person roughly comes from the intelligence agency of that country.

There are even times when people from some organizations will find people locally to make local certificates. After all, Langley cannot have any template for this kind of thing. Only those who work in this industry in the local black market can make it.

The intelligence agency will also collect various samples collected over the years to create a database. If the fragments obtained during future operations can be pieced together and compared in detail, they will know where they were probably made.

Based on these clues, the person who made the certificate can be found.

People who can prepare documents well must have a certain reputation in the local area, and it is not difficult to find them.

From their mouths, we can learn who and what person produced the certificates, and what other certificates were produced in addition to these certificates.

All details are clues.

Li Zheng listened to and memorized Xue Bing's knowledge, but what interested him most was the picture pieced together from one of the fragments.

This picture is incomplete.

There's only about half of it, and the rest is missing. It looks like it's a mechanical production drawing. I can't tell what it is because it's only half a drawing.

Li Zheng simply showed it to Xue Bing.

"Old Xue, this picture looks very interesting to me. What do you think it is?"

Xue Bing glanced at it and said: "It seems to be some kind of machine..."

Li Zheng said: "Is there any way to restore it?"

Xue Bing said: "Yes, but are you sure this thing is valuable? It doesn't seem to have anything to do with identity tracking."

Li Zheng had an intuition about this thing. He found it very interesting and felt that this picture was not simple.

"Just think of it as my intuition. I think there is something in this."

Seeing his insistence, Xue Bing nodded and said: "Okay, it's easier to restore this kind of thing, just watch it."

After that, he brought another computer.

Then input the pictures that Li Zheng put together into the software, and then connect to the database to start the comparison.

"Now, as long as there are one-third of the pictures, it is easy to compare them. If it is for civilian use, you can definitely find a matching picture within ten minutes. If it is for unpopular or military use, it may take a little longer.

"

Li Zheng stared at the constantly changing and flashing patterns in the software. After looking for a while, he still couldn't find a matching picture.
