Conan: Chief of Rice Flower's Science Points

Chapter 350 Night Baron
After learning about this, Shiraishi called Nanyang University directly, obtained Professor Hirota's address in the name of a police officer, and made an appointment to visit him that evening.

"You want to go too?" Shiraishi frowned and looked at Ai.

"Of course! I know what that floppy disk looks like, and what if he asks about your sister?" Xiao Ai said as a matter of course.

Bai Shi shook his head and said, "I will ask him, not him... If you are worried, I will bring a hidden intercom."

Shiraishi didn't want to bring Ai to the house, in case they were discovered by the "Black Organization", it would only add to suspicion.

As for Professor Hirota, Shiraishi did not intend to visit him as "Miyano Akemi's friend."

But...

"Hello, you must be the famous Director Mika, right? You are as tall as the rumors say..." Professor Hirota said in surprise when he saw Shiraishi after opening the door.

"Hello, Professor Hirota. You already know the reason why I came to see you today, right?" Bai Shi looked at the old professor with white hair and beard in front of him with a stern face.

"Eh? This... I really don't know. The school just said that you seem to have something wrong..." When Guangtian just received the news from the university, he was still a little complaining in his heart - why did the police come to me? If I don't explain it clearly, there might be bad rumors in the school later!

However, now seeing that Shiraishi had a really stern face, the old professor also became a little scared.

Fortunately, Guangtian had not done anything too bad. At least he felt that there was nothing worthy of police investigation, so nothing was cheated out of him.

He just invited Bai Shi into the house and asked his wife to make some tea, as if he wanted to have a detailed discussion.

"You know that a bank robbery happened in Haido Town a month ago?" Shiraishi asked.

"Bank robbery... I heard the case has been solved, right?" Professor Hirota nodded.

"It's not a solved case, because the last robber also shot himself before being arrested by the police." Shiraishi said, taking out a photo of Miyano Akemi and placing it directly in front of Professor Hirota: "Professor Hirota should know this robber, right?"

"Eh? How could I know him... Ah! This... How is it possible? Isn't this... Miyano-san? Could we be mistaken? Miyano-san is usually very kind, even a little indecisive..." Professor Hirota was puzzled at first, and then shocked.

"Miyano? As expected... according to the police investigation, she had a fake identity and her name was Hirota Masami." Shiraishi frowned and stared down at Hirota Masami physically.

Although he was in his own home, Hirota Masami felt as if he was being interrogated in a small dark room!
Professor Hirota was sweating at this time - after all, "your student robbed a bank and used a name that sounds the same as yours", Professor Hirota himself felt that he was a little suspicious...

"Miyano-san doesn't have much of an opinion of her own. Could someone be instructing her to do this?" Shiraishi asked, staring at him.

Guangtian was still a little drunk because he had a drink at dinner. After being frightened by Shiraishi, he was completely sober...

"No, no, no, Officer Shiraishi, this really has nothing to do with me... I... am just Miyano-san's club instructor... She must have just given him the name casually!" Hirota hurriedly explained.

"Professor Hirota, of course I believe you, but... when was the last time you met Miyano-san? What did you talk about then?" Shiraishi asked with a smile.

"We... that was probably a year after we graduated. We didn't meet privately then, it was a club gathering." Hirota Masami was so scared that he quickly confessed the truth.

"Is that so..." Shiraishi looked at Professor Hirota with scrutiny, and then said, "We have verified your reputation in the school before, and we are willing to trust you, but you'd better think about it again. Is there anything else related to Miyano-san?"

"This... yes! There is a floppy disk! I usually help students in the club to copy photos. Among the floppy disks that everyone gave me before, there is a very strange photo. It might be Miyano-san's!" Professor Hirota said quickly.

Seeing that he had taken the initiative to think of the floppy disk, Bai Shi was delighted, but he remained calm on the surface and said, "Floppy disk? Is that all? If we issue a search warrant later and find something..."

"How about... can you help me take a look first? There shouldn't be anything else related to Miyano-san." Hirota said uncertainly.

Bai Shi didn't hesitate to take out the white gloves...

Of course, Bai Shi was not trying to find out anything, but to help him check whether his home had been targeted by the "Black Organization" and whether there were any wiretap or surveillance devices left at his home.

After Bai Shi checked, he didn't find anything and just took the floppy disk away.

Before leaving, Shiraishi also reminded Professor Hirota: "This case has a very bad impact. If Professor Hirota remembers or discovers anything, please contact me in time." As he said this, Shiraishi handed his business card to Hirota.

Afterwards, Shiraishi left with Hirota's gratitude...

After all, in Guangtian's opinion, he was almost implicated, fortunately Director Mika was very observant!

Shiraishi then drove around Hirota's house and left only after making sure that there were no surveillance personnel.

The reason why he scared the old man was certainly not because Bai Shi had any bad taste.

On the one hand, it was to get the upper hand and avoid being suspected of "how do you know Miyano?" Now Professor Hirota himself must have thought that Shiraishi came to him because of the pseudonym and because he found out that Miyano Akemi was once his student.

This reason is very useful!
In the future, whether someone within the police force discovered that Shiraishi had investigated Hirota, or the "Black Organization" discovered that Shiraishi had visited Hirota Masami, there would be reason to believe that Shiraishi had indeed investigated here on his own, rather than having an insider "point the way".

On the other hand, Shiraishi is also doing this to protect Hirota!

The "Black Organization" has not reacted yet. Once they know who "Hirota Masami" is, they will definitely come to silence him.

Shiraishi came to his house first and even searched his house, so the motivation for the "Black Organization" to silence him was much smaller...

After all, even if he really knew something, Bai Shi must have already gotten there first. There would be little point in silencing an uninformed person at this time.

Although the reason for Hirota's gratitude towards Shiraishi is not right, the direction is correct!

Especially after this incident, Guangtian felt that being too close to his students might lead to some unknown consequences, so he sent back all the students' belongings that were stored with him...

In this way, we inadvertently avoided a disaster, which is cause for celebration.

……

After Shiraishi got the floppy disk, he returned to the apartment. Ai could not wait to look at him.

"Professor Hirota said that this floppy disk cannot be read at all?" Shiraishi said, handing the floppy disk to Xiao Ai. "Of course, the storage of the organization has encryption settings. If you read it normally, you can't read it, or you can only see false content. You need to use special methods to access the encrypted data inside!" Xiao Ai said as a matter of course.

Then Xiao Ai inserted the floppy disk into the reading device, opened the hidden launcher, entered the password, and then...

I saw a figure wearing black clothes and a black mask appeared on the screen, posing for a while, and then the computer became inoperable!
Seeing this, Xiao Ai panicked and said, "Oh no! There is the Dark Night Baron virus in the floppy disk..."

Before Xiao Ai could finish her words, Shiraishi realized that something was wrong with the computer and immediately unplugged the power cord and removed the battery...

Although we don’t know what happened, we must prevent the damage from further expansion and keep it physically intact, so that the possibility of recovery in the future will be greater.

"What's going on?" Shiraishi asked Xiaoai after he finished.

Xiao Ai said with a serious expression: "It should be because I didn't use the computer authorized by the organization... I have never tried to use an outside computer before..."

It seems that the data stored by the "Black Organization" is doubly insured - if you don't know the special startup method and password, you can't see the content. Even if you know these, if you don't use a computer certified by the organization to open it, it will trigger the virus!
"Dark Night Baron Virus?" Bai Shi felt that the name sounded familiar.

Upon hearing this, Xiao Ai thought that Shiraishi was confused, so she explained, "Well, it's a virus whose inventor is unknown. It appeared several years ago. Once infected, it will quickly delete all data in the system and all related systems. The inventor used it to blackmail many large groups, and then suddenly disappeared... I didn't expect that he was recruited by the 'Crow Legion'!"

The "Dark Night Baron Virus" does not have the ability to spread autonomously. It is a targeted invasion and is not open source. After all, the inventor uses it to extort money. If the entire network is full of viruses, who will extort money from him?
The "Dark Night Baron Virus" in this floppy disk can be hidden so secretly and so perfectly, most likely with the assistance of its inventor.

"Wait for me to make a phone call and ask." Bai Shi looked at the laptop in his hand that had been unplugged. He didn't dare to open it again. Instead, he made a phone call...

Of course, there is only one person Bai Shi can ask in this regard.

"Hello, Director, why are you calling me at a time when minors are not allowed to work?" Yuto started complaining after answering the phone.

This kid has become more and more cheerful recently!

Bai Shi looked at the time and it was just past ten o'clock in the evening...

"Don't be anxious. I'm not asking you to do it now. I just want to confirm whether you can do it." Bai Shi asked calmly.

As expected, upon hearing the "question", Youdou immediately became alert: "Whose system do you want to crack? As long as the director dares to take responsibility, even if it's the public security..."

"I'm not responsible! I just want to ask you... Have you heard of the Dark Night Baron virus?" Bai Shi interrupted his bragging.

"Dark Night Baron? Of course I've heard of it... but never encountered it. That thing will delete itself, and there is no sample found on the Internet." Yuto's tone was still a little strange, as if there was something he hadn't said.

After all, Yuto is only 17 years old, and the "Dark Night Baron Virus" ravaged major groups several years ago, so it is normal that he has not seen it.

"I have a computer and accidentally copied a floppy disk containing 'Dark Night Baron'. The power went out within one second after it was started. Can you restore it?" Bai Shi asked directly.

"Restore... do you mean the computer or the floppy disk?" Yuto confirmed.

"The computer is not important." Bai Shitou was not hurt by the deletion of the original things in the computer.

"I can try, but don't connect it to the power source again." Yuto didn't dare to make any promises at this time.

Although he had never seen it, he at least knew... that many large groups back then were either blackmailed or suffered heavy losses. This virus must be extraordinary!
"Come to the police station tomorrow morning and go directly to my office." Shiraishi could only try his luck.

As for Ai, Shiraishi put down the phone and asked, "Did you forget... that you promised Ayako that you would go to the amusement park tomorrow?"

"No, that's to accompany you to the amusement park...you and Ayako can go, and don't call Ayako's name behind her back!" Shiraishi rolled his eyes.

Amusement Park...

In a place like that, even Bai Shi isn't allowed to ride on the carousel!
……

Saturday, April 3.

Chief Mika was so crazy that she even came to "supervise" the training of arrest techniques on the day when the Metropolitan Police Department's police station competition just ended!

For a while, the police officers who thought they had been able to relax their training a little recently were in despair.

Of course, it’s just a side note to see how everyone’s “arresting training” is going.

Shiraishi came to hand over the notebook to Yuto, who had an appointment yesterday, and specifically reminded him: "Do it in my office... Remember, you just need to try your best to prevent the loss of files in the floppy disk. Don't look at the specific contents of the files even if they are repaired.

"Also, the network card of this laptop has been removed. If you want to connect with your own computer, you must remove the network card first. After that, do not take away any equipment you have used here. You will be reimbursed directly through the office's accounts. If you need to back up anything, you can do it now."

In order to prevent Yuto from being implicated, Shiraishi made all the necessary preparations. In short, he did not give this thing a chance to leave anything on Yuto's computer.

"Why is it that our police station has more secrets than the Public Security Bureau..." Yuto complained.

However, despite all his complaints, Yuto still remembered what Shiraishi had told him.

After Shiraishi conducted two arrest training sessions in the morning and afternoon, Yuto also gained something...

"We have only managed to save so much of the contents on the floppy disk. Some of them have been completely formatted." Yuto paused and said smugly, "He is just a Dark Night Baron, nothing more than that!"

Bai Shi did not interrupt his expansion, but...

Shiraishi estimated that part of the reason for the success was that the "Dark Night Baron Virus" in the floppy disk was several years behind the latest version and was not the latest one at all!

After all, this floppy disk was sent out by "Shirley" three years ago, and it has not been updated with the version...

But what Yuto said afterwards made Shiraishi concerned.

"It seems that this mysterious journey to Izu is not very interesting..."
