Nanlin Guiyi ordered Butler to control the security monitoring system of the Kasai Police Department.

Otherwise, this morning, how dare Nan Lin Guiyi put the envelope directly on Kato Fukuda's desk? But you should know that the police office area of ​​the police station has full coverage of security surveillance cameras.

If Butler did not control the security monitoring system, even if no one noticed Nanlin Guiyi's movements, the security monitoring camera would definitely be captured.

Now, Butler reminded Nanlin Guiyi that Kato Fukuda had checked the contents of the USB flash drive, and Nanlin Guiyi checked the time point and called Fukuda Kato.

"New discovery? What new discovery?" Fukuda Kato asked quickly, thus temporarily neglecting the issue of thinking about the source of the USB drive.

Nan Lin Guiyi smiled and said, "If I had no mistake in judgment, it should be the fingerprint left by the murderer!"

"What? The murderer's fingerprint? Really?" Fukuda Kato said excitedly. He had just found the suspect from the USB flash drive, but there was no evidence.

If Nan Lin Guiyi discovers the murderer's fingerprint and compares it with the suspect's fingerprint, as long as it is confirmed that it matches it, the suspect is the murderer!

"It should be no big problem. However, Officer Futian has only half a fingerprint. I am carrying out the collection work. Do you want to come and take a look?" Nan Lin Guiyi explained.

Fukuda Kato said affirmatively, "Well, I'll come here immediately, wait for me for a while!" After that, Fukuda Kato hung up the phone directly and then pulled out the USB flash drive.

However, Kato Fukuda didn't know that in addition to the photos of Kazuma Imai, there was also a hidden Trojan program in this USB drive. When he inserted the USB drive into the computer's USB interface, the hidden Trojan program began to run and was automatically integrated into the police system of the Kasai Police Department.

Although the police system of the Kasai Police Department is not an internal closed system, it is very troublesome to invade from the outside. Even though Nanlin Guiyi has the technology of world-class hackers, Nanlin Guiyi does not control many advanced server broilers. It is of course a troublesome to break the defense of the Kasai Police Department.

Furthermore, the police system of the Kasai Police Department is connected with the police system of the Tokyo Metropolitan Police Department, and Nanlin Guiyi eventually wants to invade the police system of the Tokyo Metropolitan Police Department.

If the computer equipment controlled is insufficient in computing power, it will rashly invade the police system of the Tokyo Metropolitan Police from the outside and will only be ruthlessly blocked.

Now it's good. Kato Fukuda took the initiative to release the Trojan program from within, providing convenience for the Trojan program. Butler easily entered the police system of the Kasai Police Department through the Trojan program.

As for the police system of the Tokyo Metropolitan Police Department, there is no hurry for the time being!

Another point is that even if this incident is exposed in the future and traced to the root cause, Kato Fukuda is unlucky and has no relationship with Nan Lin Guiyi.

Because the entry point of the Trojan program is Kato Fukuda's computer, not Nanlin Guiyi's computer!

Nanlin Guiyi was waiting at the scene of the crime, and at the same time, he checked for the missing and set up a perfect illusion, making it natural to find out the murderer's fingerprint.

After waiting for about fifteen minutes, Kato Fukuda arrived at the crime scene. Guiyi Nanlin was waiting at the door. Before Kato Fukuda spoke, Guiyi Nanlin reminded: "Officer Fukuda, please change your work clothes before entering the crime scene. In addition, wear sterile gloves, head covers and shoe covers."

Fukuda Kato suppressed his anxious mood and changed his clothes according to Nan Lin Guiyi's request, then asked: "Where is the murderer's fingerprint?"

Nan Linguiyi walked into the door with Kato Fukuda and pointed at the shoe cabinet close to the upper part, "Here! Officer Fukuda, have you seen it? Only half of the fingerprints."

Kato Fukuda frowned, "Why is it judged that it was the murderer's fingerprint?"

Nan Lin Guiyi responded, "First, the location of the fingerprint. Officer Futian, please pay attention to your feet and see the location of the fingerprint. Is it at the No. 4 physical evidence point, above the suspect's shoe print? Let's imagine a scene where the murderer is preparing to wear shoes when entering or leaving, holding the shoe cabinet with one hand and wearing shoes with the other hand. Does this half of the fingerprint just fit the location of the scene?"

In fact, how could it not be consistent?

The location of half a fingerprint is carefully selected by Nanlin Guiyi, which must meet the scenario set by Nanlin Guiyi.

Kato Fukuda thought about it and nodded, "Well. Are there any other reasons?"

"Yes!" Nan Lin Guiyi said affirmatively, "The surface of the shoe cabinet is made of glass. Officer Kato, please observe carefully. Is the lower half of the fingerprint gone?"

Kato Fukuda looked carefully and it was indeed the case.

"Although the fingerprints in the lower half are gone, Officer Fukuda, please observe whether there are some blurry traces in the position of the fingerprints in the lower half?" Nan Lin Guiyi reminded Kato Fukuda.

Before Fukuda Kato responded, Nanlin Guiyi continued, "This is because the murderer was cleaning his fingerprints. However, under normal circumstances, the fingerprints are not visible, and the fingerprint cleaning work is not thorough. Officer Fukuda, think about it, if it is not the murderer, why should you clean the fingerprints?"

Kato Fukuda thought about it and it seemed that this is indeed the case. If it weren't for the murderer, why should I clean up my fingerprints?

"But..." Kato Fukuda wanted to ask something, but was interrupted by Guiyi Nanlin.

"We have half a fingerprint, and we can match it in the criminal database, right?" Nan Lin Guiyi reminded that the so-called criminal database is a database of all arrested criminals, including fingerprints, photos, height, age, name and other information.

Fukuda Kato smiled mysteriously and said, "No! I have already obtained the suspect's photo. As long as I use facial recognition in the store, I can get the answer."

"What? Officer Fukuda, why did you get the photo of the suspect?" Nan Lin Guiyi's acting skills were very good, and he showed a look of surprise just right.

Kato Fukuda pretended to be a profound response, "One of my informants has provided me with information. Officer Nanlin, you have made a meritorious service this time. As long as this half of the fingerprint matches the suspect, the suspect will be the murderer!"

Nan Lin Guiyi responded modestly, "No, no, it should be the credit of Officer Fukuda. If there were no photos of the suspect obtained by Officer Fukuda, only this half of the fingerprint would be of no use."

Kato Fukuda was very satisfied with Guiyi's modest attitude. He smiled and said, "Guiyi, with the credit this time, as long as you pass the Inspection Minister's promotion examination next year, you will definitely become the Inspection Minister. Regarding the Inspection Minister's promotion examination, if you don't understand anything, come and ask me any time." Kato Fukuda changed his name to Guiyi and deliberately brought the relationship between the two sides closer.

Naturally, Guiyi of Nanlin would not reject Fukuda Kato's kindness, Kato Fukuda was Nanlin Guiyi's next chess piece...
