After having a clear clue, Fang Zheng immediately activated the Umbrella Intelligence Department to start a carpet search. According to Fang Zheng's orders, these people will thoroughly check all the family crests in Japan to find the family with the Katahame family crest, and then they can investigate according to the family, and then... and then.

Fang Zheng had no other choice but to sit here and wait. He could only hope that Umbrella's men could be more reliable.

As for him, he still had three meals a day, shuttling between his company and the Metropolitan Police Department.

but……

"I don't mean to say that your uncle is really good at making trouble."

Fang Zheng was driving while talking on the phone to Yuanzi.

"What does it matter, Mr. Fang Zheng? Isn't Umbrella also involved?"

"Oh... I shouldn't have agreed to it..."

Hearing Sonoko's response, Fang Zheng sighed helplessly. This all started with Sonoko's uncle. The Suzuki Zaibatsu was just like Karasuma Renya, who had nothing to do after having a lot of money. Her uncle Jirokichi had everything he needed and was only thinking about arresting Kaito Kid.

For this, he was very generous. He took out a whole page of advertisement in the newspaper to declare war on Kaito Kidd, and even said that he would wait for him on the world's largest airship. He even took out a gem ring called "Lady of the Sky" as a bet...

Of course, if that was all, Fang Zheng would have nothing to say about him except that he was stupid and rich. However, Sonoko, the uncle, heard from somewhere that Fang Zheng had defeated Kidd and arrested Lupin III. Not only did he pay a large sum of money to hire him, he also ordered a set of security equipment from Umbrella...

This made Fang Zheng depressed.

Of course, there is no such thing as pushing customers away in this world, but this is also a thorny problem. If Umbrella's security facilities block Kaito Kidd, then its reputation will naturally rise. Apart from anything else, the "defense that even Kaito Kidd cannot break through" is the best advertisement. By then, Umbrella's orders will definitely be shipped here in truckloads.

But if it fails, then Umbrella's reputation will be ruined... Fang Zheng is not willing to use his own company as a stepping stone for that kid.

After all, what he lost was real money.

So Fang Zheng secretly made up his mind that if he caught Kidd this time, he would beat him to death without killing him. Even if he had to beat him to the point where he couldn't take care of himself, he would never let his family's reputation be damaged.

However, there are still a few days before the showdown with Kaito Kidd, and the main problem now is...

Looking at the Metropolitan Police Department in front of him, Fang Zheng sighed silently.

When Fang Zheng walked into the Metropolitan Police Department's Investigation Division 1, he saw that everyone, including Officer Megure and Chief Odagiri, were already there. Everyone had a serious expression, as if their father had died.

But Fang Zheng also knew why they were so nervous, because according to the information he received, a group of armed men who called themselves Red Siamese Cats attacked the National Institute of Microbiology in Tokyo last night, stole a deadly virus, and blew up the virus library. At the moment, the entire Metropolitan Police Department was also extremely nervous, fearing that they were carrying out some terrorist activities.

"Hey, good morning, everyone."

Fang Zheng greeted him and sat down on a chair beside the table. Seeing Fang Zheng coming, Director Odagiri nodded.

"You're here, Fang Zheng. Is everything okay over there?"

"It's okay. I've already ordered the TV station to criticize the security measures of the Tokyo National Institute of Microbiology... The warehouse storing such a dangerous virus was only equipped with two security guards, and there was no warning at all during the attack... If they are not investigated for dereliction of duty, the old man in the institute will just have to wait to be laid off and go home to farm and grow flowers."

"Well……"

Hearing Fang Zheng's blunt words, the police had complicated expressions, but they were secretly glad that Fang Zheng was also one of them and had a TV station under his command. Now that Fang Zheng was taking the lead in investigating the security issues of the National Institute of Microbiology, other media would probably follow suit, which would reduce the pressure on the police.

"So what clues have you found now?"

Fang Zheng let out a bunch of empty talk, and then turned around to ask questions. He had also received a report before, but the news was unclear, so he hurried over. Hearing Fang Zheng's question, Chief Odagiri winked at Officer Megure, and the latter coughed.

"Takagi-kun, please explain."

"Ah, yes."

Gao Mu stood up quickly and spoke to Fang Zheng.

"This terrorist organization calling itself the Red Siamese Cats was actually wiped out by our police more than a decade ago. So when they issued the notice today, we also hurriedly stepped up our efforts to question the former senior members of the Red Siamese Cats who are serving sentences in prison, but they all insisted that they knew nothing about it. We have already filmed the video..."

"I see. I'll go check it out later."

This is also one of Fang Zheng's jobs. After all, he is only one person and cannot be in two places at once. Therefore, the police usually take a videotape when interrogating a prisoner, and then give it to Fang Zheng for review. Fang Zheng only needs to glance at the prisoner's expression in the video to basically judge who is telling the truth and who is lying.

"Our only clue at the moment is this ampoule."

As he spoke, Officer Sato stood up and picked up a small bottle that looked like a reagent bottle.

"This is the ampoule we found in the parking lot of the institute. There is a Red Siamese cat logo on the bottle. We have checked all the ampoule manufacturers at home and abroad, but we have not found the same style. We speculate that it should be developed by Red Siamese cat itself."

"Oh huh? Let me see."

Hearing this, Fang Zheng raised his eyebrows, then took the ampoule handed over by Officer Sato and squinted his eyes to read it carefully. At the same time, Inspector Shiratori continued to speak.

"We think that based on this, it is very likely that the red Siamese cat brought multiple ampoules into the institute. Then, they put the bacteria from the institute's storage into those ampoules and took them away. Because it is very difficult and dangerous to replace the bacteria container, we think that there must be someone among the red Siamese cats who has a considerable degree of scientific knowledge..."

"puff."

However, before Gao Mu could finish his words, he heard Fang Zheng sneer and throw the ampoule in his hand onto the table.

"Any questions?"

Looking at Fang Zheng, Director Odagiri asked, and Fang Zheng just laughed.

"Sorry, sorry, because the joke Officer Takagi just told was so funny..."

"joke?"

"Yes, Officer Takagi believes that these people have a considerable level of scientific knowledge, but if you ask me, they are only slightly better than illiterates... probably only at the level of elementary school graduates."

"…What do you mean?"

Hearing this, Chief Odagiri, Inspector Megure and others also stared at Fang Zheng, who shrugged his shoulders.

"It's very simple. Officer Sato just said that this ampoule bottle has not been found in any domestic or foreign manufacturers, so it is inferred that it was made by the other party... If it is true, then I say that this thing cannot be used as a container at all."

"Eh? Is that so?"

"certainly."

Fang Zheng spread his hands.

"Dangerous bacteria are very deadly, so the requirements for containers are also quite high. You don't think that the containers for bacteria in the National Research Institute are all handmade by the manufacturers themselves. Sealing, hardness, and heat insulation, all of these need to be considered. It takes appropriate equipment to produce this kind of raw material and mold it. It's not that you can just take a test tube and put a rubber cap on it and call it sealing..."

Having said that, Fang Zheng pointed to the ampoule on the table.

"I just checked it carefully. This thing is just a showpiece. If these idiots really used it to store bacteria, they would probably be dead by now. We don't need to investigate the case anymore. We can just collect their bodies and cremate them."

Hearing this, the others also started to think, and Inspector Megure also looked at Fang Zheng.

"Then it is indeed strange to hear what you said. Why didn't they just use the containers from the National Laboratory, but instead replaced them themselves? And why did they blow up the National Institute's storage warehouse?"

“I think this question is quite simple to answer.”

"Yeah?"

"Um……"

Fang Zheng shrugged.

"Because after the warehouse was blown up, there is one question we will never know the answer to, that is - how many bottles of bacteria did they steal from the National Institute. And my guess is..."

Having said that, Fang Zheng stretched out a hand and clenched it.

"I guess they didn't steal any bottles."

"……Why?!"

Everyone was shocked to hear Fang Zheng's answer.

"You didn't steal any bottles?"

"Yes, this is the best explanation I can think of. If they really stole it, whether it's one, two, three, four, five, six, seven, or eight, the lethality would be enough to cause social panic. To be honest, let alone five or six bottles, given the lethality and spread of this bacteria, one bottle would be enough. After all, viruses can multiply and infect. If he finds the Tokyo Tower and throws himself down without even looking at it, the whole of Tokyo will probably be destroyed in a few days."

Hearing this, everyone's faces turned even paler, but Fang Zheng didn't care at all and continued talking.

"This thing is like a biological nuclear bomb. If you hold it in your hand, others will be afraid. But there is a prerequisite, that is, others must know that you really have this thing in your hand, rather than just using fireworks to fool people. So if the criminal gang has a normal IQ, then even if they take away a bottle at random, our Metropolitan Police Department will be scared to death right now."

“…”

Although this may not sound nice, everyone agreed that... it is indeed true.

"But either these people have abnormal IQs, or they have other motives, so they blew up the warehouse. In this case, we will definitely think that they definitely took the bacteria, and the only thing we don't know is how many bottles they took. But in fact, there is no evidence to prove that they really took the bacteria, it's just what we think."

"this……"

After hearing Fang Zheng's analysis, everyone remained silent, but soon Inspector Shiratori spoke again.

"But it's also possible that the criminals did take the bacteria, and they blew up the warehouse to prevent us from developing a targeted vaccine..."

"Of course, so I am just proposing a possibility. At least if you ask for my personal opinion, this is it."

As he spoke, Fang Zheng picked up the evidence bag.

"Why don't we send this thing to Umbrella's technical research department for testing? Then we'll know if it's a fake or not. If this thing is really just a fake, and those people are really stupid enough to use it to store bacteria, then Officer Megure can contact the crematorium and cemetery right now."

"Then I'll leave it to you."

At this moment, Officer Megure also nodded hurriedly. It must be said that this possibility does exist, but as police officers, they still have to think of the worst in everything and cannot give up just because of Fang Zheng's words. But no matter what, after listening to Fang Zheng's explanation, everyone couldn't help but breathe a sigh of relief.

If these guys who call themselves Red Siamese cats were really just bluffing and didn't actually steal a single bottle, then at least the harm to society could have been avoided.

As expected, Umbrella's research department passed the news in the afternoon - after analysis, the ampoule was just a showpiece, and it was not even qualified to be used in laboratory reagents. It would not even pass the test in primary and secondary school chemistry laboratories, and using it to store deadly bacteria would be a deadly act.

The only use of it is probably to collect some sand to play with at the beach.

Fang Zheng handed the analysis report to the Metropolitan Police Department, which immediately eased the tense atmosphere there. At least if the analysis of Umbrella's research department was correct, then the possibility that this group of people were deliberately making a fuss was higher - or they were really stupid enough to use this to contain bacteria, and then all of them died in some unknown corner.

The latter is even worse.

No matter what, the search must continue. After all, this incident has caused a sensation in the whole society. As long as the Metropolitan Police Department does not catch the person, the society will not have peace.

Of course, this is the job of a full-time police officer. As a consultant, Fang Zheng can retire after providing his opinions and technical support.

For him, compared to those stupid thieves, what bothered him more was the trouble with Kidd.

And there is the elementary school slayer in front of him.

“I hope no one dies today.”

Looking at Conan in front of him, Fang Zheng silently clasped his hands together, while the latter's face was as dark as Hattori Heiji.

"What nonsense are you talking about? But never mind...How is your investigation of the family crest going?"

"There are no clues yet. We can only hope that our subordinates will not slack off."

Fang Zheng spread his hands helplessly, then looked at the young detective team who were screaming and shouting at the blue sky and white clouds outside the porthole not far away.

"It's good to be a kid, carefree."

"What does it matter? You should enjoy yourself when you are a kid."

At this moment, Professor Agasa also walked over with a smile, and Ai followed him with her eyes half closed.

"Doctor, although I know you love your grandson very much, it is not good to spoil him too much."

"Forget it. Anyway, where is Kaito Kidd? Have you seen him?"

Conan glanced around and spoke in a low voice, while Fang Zheng shook his head.

"No, this guy probably doesn't dare to confront me. He's probably hiding somewhere disguised as a staff member of the airship."

Kidd knew that Fang Zheng had the ability to see through his disguise, so it was impossible for him to disguise himself as someone Fang Zheng knew and come here to seek death. It was very likely that he was disguised as an NPC character such as a chef or a maintenance worker and stayed in a corner. However, Fang Zheng was still very confident in the security measures he designed this time... It should be fine.

perhaps.

"Hey, little ones, do you want to go to the sky observatory together? You can also see the big gemstone."

Sure enough, at this time Suzuki Sonoko, Xiaolan and Mira also came over, and Sonoko greeted the members of the Junior Detective League with a smile.

"That's great, Gem!"

As expected, upon hearing the word gem, the little kids immediately raised their hands and ran towards the three girls, while Fang Zheng followed behind speechlessly - why did this old man have to show off, would he die if he didn't show off?

Soon, everyone got on the elevator, and the cabin crew began to introduce the airship to everyone. As for Fang Zheng, he leaned aside with a speechless look on his face, not wanting to talk.

"Fang Zheng, didn't you build that thing? Why don't you say something?"

At this moment, Mira also reached out her hand and nudged Fang Zheng, and spoke with a smile.

"Not interested."

Fang Zheng glanced at the eloquent cockpit commander and shook his head helplessly.

"The Art of War by Sun Tzu says, 'You can win every battle if you know both yourself and the enemy. If you know yourself but not the enemy, you will win every battle. If you know neither the enemy nor yourself, you will be in danger every battle..."

"What do you mean?"

"What I mean is..."

Fang Zheng silently glanced at the complacent Jirokichi.

"You've lost so many times, don't you have any idea of ​​yourself?"

At this moment, accompanied by a "ding" sound, the elevator door slowly opened.

We have arrived at the Sky Observation Deck.
