Conan: The Man Behind the Romance

Chapter 205 Water Cycle! Mercury! Save!

"The city's tap water system is an integrated whole. Even if the winery research institute is an independent fortress, it has to be embedded in this system since it doesn't have its own wells. Once embedded, no matter how complicated they design the channel, water, being invisible, will find a way out on its own."

Yingsheng explained.

Xiaolan suddenly realized: "Mr. Shuiyue added something to the water pipeline of the research institute. During the time we are eating, that thing will flow into the sewer along with the water from the research institute. Then, we can search forward along that thing from the end and lead all the way to the winery!"

"good."

Yingsheng smiled and said, "After all, the people in the winery also need to eat. Even if they can eat outside on normal days, they wouldn't dare to do that this evening."

"So that's it!"

Xiaolan was quite excited: "Did Shuiyue-kun give them some kind of poison? Will it make them faint?"

"I would like to give them something like this, but there is none."

Yingsheng spread his hands and said that if Gin could give him the chronic poison at noon today, he could use it on the brewery himself in the afternoon.

"Also, considering the dilution of water flow, those people have different meal times, so even if there is a poison that can cause them to faint, we can't give it to them. Besides, we might as well alarm them and force them to move directly. Isn't it our goal to do this without anyone noticing?"

Xiaolan was a little disappointed: "Indeed, it is the best way to only use it to find the way and not be discovered by them. So, what is it?"

"Mercury, the one in the thermometer."

"Eh?!"

Xiaolan was shocked: "That's what caused Minamata disease, a major event in Kumamoto Prefecture in the 1950s, it's all in the textbooks. Oh no, we didn't do a big bad thing, to save one person, we hurt so many people."

"No, no, no, I can tell from the looks of it that you didn't pay attention in class and only have a vague understanding of the subject."

Yingsheng shook his head: "The one that causes Minamata disease is methylmercury, which is classified as organic mercury, and the safe dose is a few tenths of a milligram; the mercury in the mercury thermometer is elemental mercury, which is extremely difficult to be absorbed by the human body. As long as you don't ingest more than 1 gram at a time, you will usually be fine.

With the dilution of running water, it is impossible for people in the winery to be poisoned, let alone if it flows into the sewers and enters the sewage treatment plant, it will be impossible to harm anyone."

Xiaolan was stunned for two seconds: "Really?"

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

"... There's not much written in the book, and it doesn't seem to explain the differences between organic mercury and so on..." Xiaolan felt a little unsure for some reason. She couldn't remember whether it was mentioned in the book. "Anyway, the teacher just mentioned it briefly and said it's not important."

"Well, you just need to know that this stuff actually seeps into our lives from various places every day. It's not a big deal. The concentration at the winery research institute is just a little higher, and it can be quickly detected with PXRF."

PXRF, portable X-ray fluorescence spectrometer.

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

Moreover, private individuals can also buy it at will.

"All right……"

Xiaolan felt that her status as a top student had been hit, and she muttered, "Suiyue-kun really knows a lot."

Yingsheng smiled: "Miaoyin knows everything. Even if I ask her about logical paradoxes and the ultimate answer to the universe, she will deduce it for me step by step in a language I can understand, leading me to come to the conclusion or lose interest. I am just slightly immersed in the light of her wisdom."

Xiaolan was silent.

Shuiyuejun means that he is self-taught?
Ah, he is an absolute genius...

Diwu——

Beep——!
Suddenly, a siren sounded in the distance. Xiaolan's heart tightened and she subconsciously held the Uzi.

This made Yingsheng stunned. He shook his head and laughed, "I say, you don't have to be so guilty. It's better for you to surrender than resist arrest violently. Not to mention, they are not coming for us. I can't even exceed the speed limit in this Santana I'm driving."

Xiaolan quickly let go of the gun and said unconvincedly: "I'm just a little nervous. If you hadn't said this so quickly, I would have let go."

"I'm very sorry. I confess. Pay attention to the source and direction of the sirens. Don't you think this could be something related to us?"

"Related to us?"

Xiaolan listened carefully for two seconds: "The police car should be on the street next to us, and now it is heading parallel to us... Hey! Could it be that Miss Aida guessed that she would be in danger and called the police?!"

"That's most likely the case. The sirens appeared suddenly, which means they came from a vertical road and turned over here. Combined with the direction of the Metropolitan Police Department, the target is quite clear. It can't be that another murder happened in this direction."

Yingsheng had already stepped on the accelerator to the bottom, and at this moment, he added a little murderous intent to increase the speed by three points.

"If it was really Miss Aida who called the police, then she is in danger. She must have a bug installed by the winery, which will only speed up her silencing."

Yingsheng estimated the distance from the Metropolitan Police Department to the current location of the police car, and how long it would take according to their speed. Assuming that Aida Masayo left the institute immediately after hanging up the phone, and called the police as soon as he came out...

The direction she fled to should be the Metropolitan Police Department, but since she had sensed the danger, she chose a different route...

Would they deliberately go against the trend?

The brewery found Hotaru's bug on her, so there was no reason for Masayo Aida not to suspect that the brewery would also install one on her.

Is Masayo Aida a fool?
Wouldn't the people at the winery be able to think of this immediately?

Yingsheng turned the steering wheel and thought, how could there be real idiots in this world!
Half a minute later, smoke began to come out of the hood of the Santana, and the sirens that had been faintly audible before had long disappeared.

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

Yingsheng discovered a problem. Doesn’t [Frenzy] have a diminishing marginal effect?
Is there an exception for machines?

Or maybe the current power is still within the maximum limit of the engine, but the heat dissipation cannot keep up?
Chi chi chi——! ! !
Arriving at the foot of the tallest building nearby, Yingsheng parked the car with a tailspin, got out of the car, picked up his pockets, and walked to the lobby on the first floor:
"Xiaolan, you continue to rush towards the research institute. I'll go up to find someone. Remember to wear a mask when you rescue people. I don't want to use a sniper rifle in the city unless it is necessary. It's too arrogant and will have subsequent effects on Ms. Aida."

Xiaolan nodded, got out of the car and took a look at the hood. Assuming it wouldn't catch fire, she turned around and ran away.

Yingsheng walked into the hall.

In the headset, Qingzi spoke softly:
"I didn't expect that Hotaru-kun would become a positive character."
