The Phantom Thief of Heart! But Conan.

"Yes, I was hired as a technician five years ago. I was previously an employee of Europol..."

Facing the police's questioning, Grace adjusted her hair and remained calm.

As for his professional background, he did not lie at all and had been living under this identity for more than five years, so he was not worried at all that any police officer would question his background based on his resume.

So he is not only cooperating with the investigation, he even has the energy to package his own character.

"To be honest, I actually discussed system security with Ms. Naomi in the early stages of the project. I believe the current level of protection is still insufficient, not to mention that we need to connect to the global network system, which means that the number of external interfaces we need will be extremely complex... However, I didn't expect something like this to happen in the early stages of operation, just after connecting to the second center."

He frowned slightly and sat in a very relaxed and gentle posture, looking like a non-aggressive intellectual figure.

"So, you think the root of the problem is that Miss Naomi's safety protection is not sufficient?" Megure Jusan asked directly.

"It's not her fault. She's just the developer of the algorithm. This isn't something she should be worrying about." He subtly pointed the finger at Makino Yosuke, feigning a familiarity with the victim as he angrily declared, "This kind of thing happened so soon after we launched. I really think we need to suspend the system. At the very least, we need to screen for vulnerabilities, remove backdoors, and conduct a new security assessment before we can put it online. We don't have the capabilities to use it yet."

"Impossible, absolutely impossible!"

Faced with the idea conveyed by the police, Makino Yosuke rejected it without thinking.

A security vulnerability has already occurred, but how to deal with it and whether to shut down the system for maintenance are not within his authority to decide.

"If the European part is shut down right now, not only will Interpol lose face, but our partners will also be extremely dissatisfied. Ultimately, the problem originates in Frankfurt..."

He didn't say it very clearly, but Megure Jusan still understood and gave him a look of pity.

There was a problem with the division of responsibilities, and because of this omission, the core engineer disappeared.

Things can easily turn into a dispute between the two sides. Makino Yosuke, who is caught in the middle, not only has to take responsibility, but also dares not make decisions easily, otherwise if any accident occurs, the responsibility will fall on him.

Makino Yosuke is now in a dilemma and can't even make his voice heard. His position as the person in charge is in name only.

"Why are you in charge of the investigation?!"

Unlike his previous two colleagues, Reinhardt had a completely different attitude.

Shiratori Renzaburo, already aware of his argumentative nature, remained unmoved: "When were you transferred to Interpol?"

"Our facilities are located on the high seas and have not entered your jurisdiction. You have no right to interrogate citizens of other countries!"

"Regarding the missing Ms. Naomi, how is your relationship? Are there any conflicts?"

"Lawyer, I need a lawyer. I won't say a word until my lawyer comes!"

After being scolded by Reinhardt's irrelevant words, Bai Niao felt a lot more friendly and kind, even when facing Ed, who obviously had little to say to tell the truth.

"Of course I won't agree to stop using it. This isn't something Director Makino can decide on his own."

Ed shrugged at their statement and didn't even bother to get up from his seat.

Deactivating the system requires the consent of more than half of the authorized engineers. Now, except Grace, no one cooperates, so the road to deactivation and investigation is blocked.

"I heard that you used to work in a world-class IT company. Why did you choose to work here?" Kuroda Heibei did not continue to ask about the content of the case, but instead asked about the background.

"The technical capabilities here are quite strong, and the work we do is interesting. Look, isn't this an exciting case?" Ed smiled, looking fearless.

Shiratori Renzaburo glanced at the records for a few seconds and said nothing.

In fact, the reason is not complicated. The main reason is that at Ed's age, as an Indian engineer, there is no room for advancement for him, and Pacific Buoy promised him a management position. In comparison, he finally chose this side.

He wasn't sincere, but considering his background, he certainly had no need to harm the system, and this was a rare job opportunity for him.

Shiratori then shook her head at Kuroda, and the two of them did not continue to argue. After a brief communication, they turned around and left.

Conan, who had been listening secretly all the way, fell into deep thought.

The information he received was different from that of the police. On the surface, these people really had no need to harm the Pacific Buoy. The problem was that if someone from the organization was mixed in, then the background that the police could find was just part of the disguise.

Whether the murderer is impersonating a non-existent person or replacing an existing person, the normal case investigation process will not lead to finding the murderer.

It’s getting late, what should I do next…

While Conan was thinking, Tang Ze, who had taken the time to go to the hall and open two locks for his teammates, had already turned into the corridor and blocked Grace who was walking towards the tea room saying she wanted a glass of water.

"You're the one helping with the coffee. What's up?"

Under the surveillance in the corridor, Binga could not reveal his true nature directly. Facing the young man who was looking at him with unpleasant eyes again, he could only try to keep smiling.

"No, I'm just thinking about something." Tang Ze tilted his head, a gentle and kind smile on his face, but the words he said were very heartbreaking, "I thought seriously about it, Miss Naomi disappeared in the bathroom, this is quite strange."

The flaws in this case are very obvious. If we have to blame it on the other two people, we can indeed say that the person who implanted the backdoor can open the sea entrance and naturally can also check the surveillance. It would be easy for him to confirm Naomi's movements. But no matter how you look at it, Grace, who was in the tea room with him and Naomi at the time, knew Naomi's movements best.

Using backdoor programs to muddy the waters can indeed blur the focus of the problem, but it cannot clear him of the biggest suspicion.

The only reason Conan didn't lock onto him directly was simply because he knew in advance that Binga was a male, so he had a preconceived notion.

"...Indeed, if Naomi hadn't gone to the bathroom, it wouldn't have been so easy for the intruder to succeed." Binga pushed his glasses up, remaining calm and giving a somewhat apologetic smile. "It's my fault. I should have gone with her or waited for her."

Tang Ze widened the curve of his lips, but didn't say whether he believed it or not.

He looked around and sighed, "It's quite surprising that a personal threat would appear in such a heavily guarded place. It's a pity that it's getting late. We should almost leave here. I'm really worried about Miss Naomi."

"Oh? Are you leaving? I thought the people the director invited would also cooperate with the investigation. We have empty rooms for visitors..."

When Binga heard Tang Ze say that he was leaving, he blinked quickly and said words to keep him, but he was secretly suspicious in his heart.

By leaving immediately, does this person really have no other thoughts about the case and the system? Or has he actually become suspicious of himself and is planning to report the problem after leaving?

"Yeah. I'm still very curious about the system, and I also want to know Miss Naomi's whereabouts, but I have other plans tonight, so I can't wait any longer." Tang Ze sighed regretfully, "There's nothing I can do. Time is money."

Binga's pupils suddenly shrank.

"See you next time, Grace...さん."

"さん" is a commonly used honorific in Japanese, regardless of gender or age.

However, his subtle pause made Binga subconsciously feel a pang in his heart, as if the pronoun the other party was going to use after the name was not this one.

After Tang Ze finished speaking, he walked past him and headed towards the main control room. Binga took a deep breath, adjusted his mood, and continued to move forward.

After walking a few steps, he saw the tea room at the corner of the corridor. He suddenly felt that this room was particularly dazzling and walked in with a stern face.

Since he said he wanted to pour water, he couldn't go back empty-handed, so he could only pick up the kettle and pour it into the paper cup.

However, just as he picked up the full kettle, he found a line of letters written in water stains on the metal table below the kettle.

【Greetings.KMR.】

Is this what the guy just left behind? KMR, what are you referring to?

His expression couldn't help but darken. Binga stared at the words for two seconds, then pulled a piece of cloth on one side and wiped it off.

Whether it is true or not, I have to speed up, this place is not safe enough.

On the other side, Tang Ze in the corridor was talking to himself in a low voice.

"He doesn't know about Kumail's existence. No problem, just brute force will do. Don't worry about hidden routes. Don't worry about the means, Noah, just control the system. I need you to use the algorithm to generate something..."

----

"Judy, Judy?"

"Oh, sorry." Judy looked away and gave an apologetic smile to her colleague. "I feel a little uneasy when I think about Nina's situation."

They are here to contact Europol, and they can't let them down at this time.

"They haven't found her body yet. No news is the best news." James comforted.

Having just dealt with the mess in Japan, they shouldn't have so much spare time to care about things elsewhere. However, at the moment, Nina's situation is likely to be related to the organization.

The main reason they were able to determine this was due to the information provided by Rena Mizunashi.

After Shuichi Akai's death, Rena Mizunashi returned to the organization and was their only guarantee to continue working. Now that she has been found, it is necessary to find out what happened.

When the three people walked out of Frankfurt Airport, they saw a car parked at the arrival exit and someone coming to pick them up.

"Hello, I'm Hans from Europol. Thank you for your willingness to assist at this time."

The man who came up to shake their hands spoke English with an accent, but judging by the strength of his handshake, he seemed quite sincere.

Europol does not have its own police force. When such a serious criminal case occurs, it is useless to rely solely on the assistance of the local police.

"I'm sorry that you have to face this situation. Have you found any clues about Nina now?" Judy took the initiative to shake hands with him and got straight to the point.

"We followed the traces at the crime scene and found some bloodstains she left behind, but the trail ended at the riverbank." Hans sighed heavily, looking pessimistic. "We've already searched the coast and... we've also hired a search and rescue team to establish a search area. Before I came here, I heard you mention it, Miss Judy, did you know Nina?"

It is impossible for a living person to disappear out of thin air, and the probability of Nina surviving after discovering the intruder's crime scene is extremely low.

They have already prepared themselves for the possibility that they may not find anyone simply because the body may have sunk to the bottom. They say they have not given up the search, but in fact they are preparing to salvage the body.

Judy lowered her eyes, her expression gloomy. "Yes. A few years ago, I came here to assist with an investigation and worked on a case together, and I had some contact with her. We got along very well and quickly became friends."

"Oh, I'm so sorry..."

"No need to be polite. The only way we can find her now is to find the criminal." Judy put away her expression and said solemnly, "Take us to the crime scene. I heard that's a data center that was recently built a few years ago?"

"Yes. It's not just here, it's connected to surveillance cameras from almost every member country. Now, besides Nina's disappearance, we also have to figure out what the intruders did." Hans led them towards the car and asked, "You guys came from Japan. Do you have any good police connections there?"

"Yes, there is. But why are you asking this..." Judy couldn't help but frown.

She knew there was something fishy going on, but why was it related to Japan...

"Oh, if possible, I hope you can help us communicate with them. We received a notice..."

"...Naomi Argento, was kidnapped?"

Akai Shuichi paused while wiping the accessories, stood up, looked again at the other side of the house which was pitch black and seemed to be unoccupied, pulled the curtains again, and frowned.

Tang Ze not only went there himself, but also dragged a whole room of people over.

He had reason to believe that Tang Ze would not stand idly by and watch the organization's actions, but Binga still succeeded. Does that mean that Tang Ze was the assistant who helped Binga in the past?

That's even more impossible. The organization sends a carefully disguised undercover agent A to assist another carefully disguised undercover agent B. If something goes wrong, won't both parties be in trouble? Even if their boss is insane, he can't make such an outrageous mission request...

"The best case scenario right now is that she's been kidnapped." Conan leaned on the windowsill. "If they really value this system, they wouldn't kill her so easily. That would be like drying up the pond to catch fish."

"Kidnapping, threats, and seizing the technology... these are indeed their common tactics." As if remembering something, Akai Shuichi's voice was cold. "Since you can contact the police and the participants in that system now, investigate the interpersonal situation of this engineer. If something happens to them tomorrow or the day after tomorrow, it means her chances of survival are very high."
