He's in Detective Conan, and he's the mastermind behind everything.

Ying Sheng was speechless: "Didn't you say it was in the textbook? You're a top student, don't you even remember this?"

"...The book doesn't mention much about it, and it doesn't seem to explain the differences between organic mercury..." Xiaolan felt inexplicably unsure, and she couldn't remember if it was mentioned in the book. "Anyway, the teacher just mentioned it briefly and said it wasn't important."

"Alright, anyway, you know that this stuff seeps into our lives every day from various places, so it's not a big deal. The concentration at the winery research institute is just a bit higher, which can be detected quickly with PXRF."

PXRF, Portable X-ray Fluorescence Spectrometer.

It is widely used in environmental monitoring, mining exploration, metal recycling and other fields, and is suitable for detecting heavy metals such as lead, cadmium and mercury.

Moreover, private individuals can buy them freely.

"All right……"

Xiaolan felt her academic excellence had been challenged and muttered, "Shuiyue-kun really knows a lot."

Ying Sheng laughed: "Miao Yin knows everything. Even if I ask her about logical paradoxes and the ultimate answer to the universe, she will use a language I can understand to deduce it for me step by step, leading me to the conclusion or to lose interest on my own."

I have only been slightly influenced by the light of her wisdom.

Xiao Lan remained silent.

Does Shuiyue Jun mean that he is self-taught in everything?

Ah, he's an absolute genius...

Beep—

Beep—!

Suddenly, a police siren sounded in the distance. Xiao Lan's heart tightened, and she instinctively gripped Uzi.

Ying Sheng was stunned by this, and shook his head with a laugh: "I say, you don't have to be so guilty. Even if you just surrendered, it would be better than violently resisting arrest. Besides, they're not after us. My Santana isn't even that much over the speed limit."

Xiaolan quickly released the gun, and said indignantly, "I was just a little nervous. If you hadn't said that so quickly, I would have already released it."

"I'm very sorry, I repent. Listen carefully to the source and direction of the siren. Don't you think this might be another matter that concerns us?"

"Relevant to us?"

Ran listened intently for two seconds: "The police car should be on the street adjacent to ours, and it's currently traveling parallel to us... Wait! Could it be that Miss Aida guessed she was in danger and called the police?!"

"That's most likely the case. The siren came out suddenly, which means it came from a road perpendicular to this one and turned here. Judging from the location of the Metropolitan Police Department, the target is quite clear. It's unlikely that there was another murder in this direction."

Ying Sheng had already floored the accelerator, and with a thought, he added a touch of killing intent to increase the speed by three times.

"If it was indeed Ms. Aida who called the police, then she is in danger. She must have a listening device installed by the brewery on her, which will only hasten her being silenced."

Hotaru estimated the distance from the Metropolitan Police Department to the police car's current location, and how long it would take at their speed. He assumed that Aida Masayo left the research institute immediately after hanging up the phone and called the police as soon as he came out...

She likely fled in the direction of the Metropolitan Police Department, but given her premonition of danger, her choice of route...

Could it be a deliberate departure from the intended path?

The brewery found a bugging device on Hotaru on her, so there's no reason why Aida Masayo wouldn't suspect that the brewery would also install one on her.

Is Masayo Aida an idiot?

Wouldn't the people at the brewery think of these things immediately?

Ying Sheng turned the steering wheel. How could there possibly be any real idiots in this world?!

Half a minute later, smoke began to rise from the front hood of the Santana, and the faint sound of the sirens that had been audible earlier had disappeared.

A minute later, the white smoke was tinged with black.

Ying Sheng discovered a problem: Doesn't [Berserk] have diminishing marginal returns?

Is there an exception for machines?

Or perhaps the current power output is still within the engine's maximum limit, but the cooling system is simply not keeping up?

Chi chi chi——! ! !

Arriving at the foot of the tallest building in the vicinity, Ying Sheng executed a drift to park, got out of the car, picked up a bag from the back door, and walked towards the lobby on the first floor:

"Xiaolan, you continue towards the research institute. I'll go up to a higher point to find the person. Remember to wear a mask when you rescue them. I don't want to use a sniper rifle in the city unless absolutely necessary. It's too arrogant and will have a negative impact on Miss Aida."

Xiao Lan nodded, got out of the car, glanced at the hood, guessed it wouldn't catch fire, and then sped away.

Ying Sheng entered the hall.

Through the earphones, Kiyoko spoke softly:

"I never expected that Hotaru-kun would become a positive character."

Chapter 206 Is Kiyoko's love for Hotaru genuine?

"On the surface, Shuiyue Yingsheng has always been a good person, right? Qingzi, thank you for your hard work," Yingsheng said.

"Ugh……"

Kiyoko sighed softly, "Who was it that told me to relax? And then they sent me to such a disgusting place! Do you know how much psychological damage that did to me? I'll have to take at least ten showers tonight!"

"I'm so sorry, you've really been a great help. To be honest, I was worried about who to ask for help, but you actually agreed to come. I'm so grateful to you."

"It's all because of me. I don't want more people to know my identity."

Kiyoko's tone was mournful, but it immediately rose again: "Hotaru-kun mentioned the voice changer before, is that what you wanted to use to cover up my existence?"

"Yes, Akemi Miyano has seen you, but she can no longer contact the distillery. Gin and Vodka have only heard your voice and don't even know if you're a human or a ghost. I guess they themselves are more inclined to believe it's a voice changer."

"So, if we demonstrate our voice-changing ability later, we can roughly solve this problem, right?"

"There's no need to deliberately show it off. If they can detect it, they will; if they can't detect the voice change, they certainly won't be able to detect you."

"Hmm, that sounds impressive. So, who does Hotaru-kun plan to send to visit Professor Agasa?"

"You don't really want to go, do you? He's Kudo's neighbor. What if you bump into him? Besides, if the voice changer passes through your hands, Ran will know who you are."

"It's not that I want to go, I just want that person to help me ask if Professor Agasa has any medicine that can remove birthmarks."

"A birthmark? Aoyagi-san?"

Ying Sheng was quite puzzled: "Aren't you worried that after she gets rid of her birthmark, she'll become more confident and change her hairstyle? If that happens, it will be even more troublesome for you to replace her."

"That kind of thing is still a long way off. Right now, if I want to be friends with her, I have to be genuinely good to her first, and besides..."

"Hmm, is it because of the environment before? I feel like throwing up just thinking about that face now. I guess I should get a little makeover."

"I'm sorry to trouble you, I'll have someone ask around, but even if such a thing exists, it can only be given to her by someone else. Also, why don't you just take her to get plastic surgery?"

"Her family's financial situation is not very good. If I give her money... then even in class, she would probably show more affection to me, to the other me."

"That's really a problem. I'm sorry, Kiyoko, it's all my fault. Things didn't go as planned, and we'll have to figure out how to use the disguise skill later."

Ding dong——!

The elevator reached the top floor. Ying Sheng turned into the fire escape. The door to the rooftop was locked. He reached out, grabbed the lock, ripped it off, and stepped onto the rooftop. A gentle night breeze was blowing. It was already 7:45 PM. The sky was dim, but the city lights were already twinkling.

Ying Sheng walked to the edge of the rooftop, took out a monocular scope, and while adjusting the knob, looked around below to guess where he was going.

"Qingzi, actually, I've already sent that human skin mask to the testing center for analysis, and we've basically figured out its composition and such."

While it's impossible to restore it immediately, it's not entirely hopeless, especially since computer programs can be used to exhaustively search through the material proportions.

"Huh? Does that mean I can actually learn the art of disguise on my own? That makes sense. Come to think of it, while the Six-Eared Macaque's seventy-two transformations are amazing, facial changes are basically just a human skin mask plus makeup..."

"Well, I'm actually quite good at the latter."

"Oh? Haven't you always been using your natural talent to pretend to be innocent and pitiful?"

"There are many types of innocence, you know. Mr. Liuying couldn't possibly be unaware of that, could he?" Qingzi smiled gently. "I'll continue practicing makeup, but speaking of which, shouldn't I perhaps learn sculpting or clay modeling?"

"These must be components of the art of disguise. I will hire a teacher for you to come to my home and teach you individually. Don't be lazy."

"Hehehe, if you saw the terrible state I'm in right now, you'd know I'm the most hardworking woman in the world."

"Thank you. If I were here with you, I would definitely give you a hug."

"Then I'll wait for you here."

"There's a possibility of a firefight there later, and to avoid getting caught in the crossfire, you should leave as soon as possible. Besides, I've been with Xiaolan the whole time, and it wouldn't be right to tell her that there are actually two of you in the world."

"Alas, my life is so bitter. I'm just a tool after all. Alas, I've met the wrong person and encountered a heartless man. Alas..."

"Stop!"

Ying Sheng was speechless: "Just say what you want, don't keep sighing here."

"Actually, I just have some questions for Ying Sheng-kun. When did you take that notebook? And what happened with the fire in my house?"

Kiyoko said, "You only discovered the true identity of the Six-Eared Macaque after I met Miyano Akemi, and devised the plan to ambush Gin and the subsequent events, but those two things happened before that."

"Ha, I thought you wouldn't ask about the process as long as the result was good."

Ying Sheng sighed softly: "Of course I found the notebook when you moved. How should I put it, I was the one who contacted those people. You were a bit too careless."

As for the reason, it is, of course, the drug modification mentioned by the winery.

You said it was true last Monday night, but twenty-three days ago, in the early morning when I first returned home from Kabukicho, I searched the house thoroughly and found nothing.

Interestingly, the distillery actually found some things in my house last Monday night.

"Qingzi, this contradiction is too obvious! If you're not the one causing trouble, then who is?"

Kiyoko readily admitted, "I'm sorry, because you left without even cleaning up the scene after the murder that day, I thought you had given up on yourself. The research qualifications of the Mizuki couple involved me, so I had to take them away."

"After the distillery came to search my house, you secretly gave them some information so that they would focus all their attention on me?"

"Yes, just like another reason you sent the notebook to the winery's research institute."

"Then we really are on the same wavelength."

Hotaru smiled. "Back to the fire at your house, I burned it down just to get Vermouth to stay at the Kudo's house. Later, after I found out her true identity, I took advantage of it and set up other traps. As for that safe..."

At a fire scene, a bomb disposal officer in a full-body bomb suit stared at the screen of the instrument in his hand for two seconds, stunned.

He looked up at the safe on the side and paused for two seconds.

There's a... inside.

A clown doll with a red nose?

Are you kidding me?!
