Real-time synthetic images.

Although this is the only explanation, the male police officer clearly still doesn't believe it.

"But does this technology really exist? I have never heard of it."

In response, the girl only replied indifferently.

"It's normal for you not to have heard of it, after all, this technology hasn't been developed yet, it's just a hypothesis."

Upon hearing this, the male police officer couldn't help but widen his eyes.

"But there are eight surveillance cameras on the seventh floor. If it's just one, it's understandable, because that kind of technology should already be at its limit when used on one image."

"Well, although it may sound simple, it's actually very difficult to control the characters in real-time and make them look natural enough to not be detected as synthesized. Even if multiple people control it at the same time, it's still very challenging. Once there's a slight mistake, it's easy to be discovered."

"Then it should be possible to achieve it using computers."

"Even if computers can achieve it, there's no guarantee that it will be foolproof. After all, no one can predict what kind of results it will produce. It's hard to achieve the expected effect, and computers can only do things that follow certain rules."

The male police officer candidly admitted to the girl's deduction.

"Indeed, the movements just now were quite natural, without any stiffness. It's difficult for a computer to achieve that."

"Yes, not only is it difficult, but even if a computer is used, there needs to be some anticipation in order to make it execute. For this type of spontaneous image, there's no way to achieve it with a computer."

"But in fact, the images from these eight cameras look very natural, without any strange parts. Is the culprit really using some other method? Like some kind of superpower or magic."

The male police officer tried to propose other possibilities.

"While it is possible to achieve that effect from that aspect, such as illusions, the abilities in that area can only affect human senses at most, and ultimately cannot deceive machines."

"But the camera on the eighth floor also didn't capture the culprit's figure."

"That is only natural, right? Since they can do that, it's not difficult for them to find a way to prevent the cameras from capturing them."

After ruling out other possibilities, the male police officer now had to face the possibility he least wanted to face.

"Then..."

"Yes, to make all eight cameras monitoring the seventh floor have that effect from different angles, although we don't know how they achieved it, it's obvious that it was done by a person, and it was done by one person. After all, as I mentioned earlier, it's very easy for the images to appear unnatural if multiple people collaborate and there is inconsistency. Moreover, even if one person can accomplish this, it is almost impossible, let alone multiple people. In other words..."

The girl paused slightly as she spoke.

"One person simultaneously controlling eight cameras in different directions at the same time, ensuring that there are no flaws in the images displayed by the eight cameras at any given moment, and achieving the effect of them filming the same thing as if they were one... Doing such an almost impossible thing that nobody can do right now... In any case, this is far beyond the abilities of an ordinary person, and..."

The girl fell silent for the first time, appearing somewhat unusual.

"And?"

"Since they can do this, I believe the security system of the vault should be a piece of cake for them, even if it is a national-level security device..."

"So, does that mean the culprit has already opened the vault?"

"Yes, and now that they have achieved their objective, the culprit should try to escape."

"But in the current situation where they are already surrounded..."

"That's correct, just like you said, since they are already surrounded, the culprit will definitely try to escape to the rooftop. Although we don't know how they plan to get away, they will definitely try to do so."

"Then I will immediately inform them to surround the rooftop."

Saying that, the male police officer immediately picked up the walkie-talkie.

At this moment, the girl walked alone towards the door. Seeing this, the male police officer quickly called out to her.

"Miss Katsuragi, where are you going?"

"Of course, to catch the culprit."

"Catch the culprit? But others have already gone to do that, right?"

"Since they can do this, it means there is at least one more person involved. Furthermore, based on the current situation, the other person shouldn't have much physical strength besides exceptional strategy and this terrifying computer technology. I am also very interested in that person, so I am only going to catch the remaining one."Without looking back, the young girl left after saying that. Although the male police officer was surprised by Miss Katsuragi's statement, "I'm very interested in that person," he didn't just stand there stupidly. Instead, he quickly chased after her, knowing that if something was wrong with the girl, he wouldn't just let her walk away.
