The cross-dressing master in the world of Detective Conan

Undoubtedly, this poisoning occurred through ingestion. Moreover, potassium cyanide works very quickly, inhibiting the action of respiratory enzymes in the body, causing cells to suffocate and resulting in symptoms of difficulty breathing.

In general, ingesting 50 to 100 mg is fatal, and it can be transmitted through the air; skin contact with wounds can also lead to poisoning.

However, compared to oral administration, the onset time through the wound is still less severe.

Furthermore, potassium cyanide is hygroscopic and deteriorates in both air and aqueous solutions, making it difficult to store. Generally, it requires the addition of a desiccant.

Kaoru Kazama stood up and looked around the room, but did not find any similar containers.

That basically rules out the possibility of poisoning on the spot. Since poison enters through the mouth, there aren't many ways to administer it.

However, the black tea has been tested and no acidification-reduction reaction has occurred, making poisoning through black tea virtually impossible, since everyone's black tea was poured from the same teapot. Yet, only Da Shang Zhu Shan died.

What else has he touched with his mouth?

Kazama Kaoru observed carefully, and suddenly, he noticed Oogami Shuzen's fingers.

Unlike the other smooth and intact nails, the thumb nail is pitted and uneven, clearly indicating that it has been bitten.

Many people have a habit of biting their nails, especially when they are under a lot of stress, they are more likely to unconsciously bite their nails to relieve stress.

Fingernail crevices are a breeding ground for filth and all sorts of bacteria and viruses. If the other party was targeting Da Shang Zhu Shan with poison because of this habit, then it would indeed be possible to bypass the rest of them and kill Da Shang Zhu Shan.

Kazama Kaoru tightened her white gloves, raised Oogami Kissen's right hand, took a small glass of water from Miss Aki, and gently poured a drop onto Oogami Kissen's finger.

Then he reached into his pocket, ostensibly to rummage through it, but actually to retrieve a pH test strip from his system space.

"I didn't expect you to bring this along."

"Ms. Gunda, don't you also carry this luminol reagent with you at all times? We're pretty much the same."

Potassium cyanide is readily soluble in water, and the resulting solution is strongly alkaline.

This is the second testing method besides the bitter almond flavor, and it is also a relatively scientific and accurate one.

As Kaoru Kazama expected, the test strip quickly showed the color of a strongly alkaline solution.

If the area contaminated with potassium cyanide is the right thumb, then the location of the poisoning is immediately clear.

It's the handle of the teacup, right where the thumb touches. If the thumb gets contaminated with potassium cyanide, Da Shangzhu will unconsciously bite his thumb whenever he gets nervous, and then facing death is to be expected.

"As expected of a renowned detective from the Tokyo Metropolitan Police Department, he's got real skills."

Kaoru Kazama made a big show of himself in front of these famous detectives, and although he didn't say it, he was secretly quite pleased with himself.

"That murderer, isn't that the Phantom Thief Kid you've been talking about? But I've heard people say that Phantom Thief Kid never kills anyone, right?"

Ran asked curiously, without a doubt, she had heard it from Sonoko.

"To be honest, as far as I know, this is the first time something like this has happened."

Hakuba Saguru then said, "They say the person who knows you best is your opponent. Hakuba Saguru, who has been dedicated to fighting Kaito Kid to the death, undoubtedly knows this person quite well. Moreover, he has actually found out Kaito Kid's true identity. How could a high school student, no matter how mature his mind is, kill someone so casually, especially someone who is completely unrelated to him?"

Da Shang Zhu Shan is known as a food detective. He spends half of the year traveling around the world to sample delicious food, and he combines his foodie journey with the entertainment of solving cases.

To become a famous detective, one must first possess the physique of a grim reaper, capable of stumbling upon cases by chance. The more cases one encounters, the higher the chance of becoming famous.

Therefore, according to this logic, the fact that Conan was able to make Kogoro Mouri famous in such a short time is enough to prove that his death god buff far exceeds that of the others present.

As expected of a child chosen by Death, its power is terrifying.

Why are you looking at me? Is there something on my face?

Conan, who was crouching down to examine Ogami Shuzen's body, felt Kazama Kaoru's unusual gaze and couldn't help but look up and ask a question.

"It's nothing, I was just curious. Please continue."

Conan, having received a perfunctory answer, did not pursue the matter further. In his view, Kazama Kaoru was simply a woman with a terrible personality.

"Well, there's no point in saying all this now. I wonder if anyone's interested in checking if the car we're listening to outside is really destroyed!"

This time, Harufumi Mogi finally revealed his true colors. Despite his calm and cool demeanor just now, his heart was actually bleeding.

“I agree. If we’re lucky, we might be able to find one or two more cars, and then we can drive away from here.”

So, everyone decided to go out and check on the car.

Going down the stairs to the second floor, I could already hear crackling sounds outside the door before I even reached the front door, so the fire was still burning.

"Ah, it's the car I rented."

When Kidd's character, Uncle Mori, saw the car completely engulfed in flames, he quickened his pace, then accidentally fell flat on his backside.

He portrayed the character of an older man perfectly, and his acting skills far surpass those of young, handsome actors of the same age. He could probably win an Oscar right away.

"Looks like my Ferrari won't escape this fate either."

Compared to the older man, Ikumi Gunda was much calmer. Despite her luxury car being blown up, she showed no sign of distress. Could she be described as an unfathomable female tycoon?

The woman who was also Harufumi Mogi's wife, and the Alfa Romeo that was "defiled" by Uncle Mori, suffered the same fate.

However, when everyone inquired about the ownership of the car, an extra Bentley was mentioned, and it didn't belong to any of the people present.

Finally, the maid, Aki, said that she had seen the car parked in front of the villa when she arrived in the morning, so it seemed that it was most likely the car of the mastermind.

That's really ruthless; to prevent them from escaping, they were even willing to damage their own car.

Tsk tsk, if you don't want it, you can just give it to him to drive, why waste it like this?

"It seems that the car I parked by the back door was probably destroyed as well."

"What? You mean there's also a car?"

For a moment, everyone's attention was drawn to what the maid, Aki, had said.

Only Kaoru Kazama noticed that she also bit her thumb when she said those words.

Could this be a coincidence?

Chapter 230 The Secret Hidden for Many Years by the Tycoon Karasuma Renya

"What did you say? You said there are still cars at the back gate?"

Maid Aki was taken aback by the sudden excitement of the crowd, but she continued:

"Yes, the owner specifically instructed me to park the car at the back gate."

"Where is the shortcut to the back door?"

Conan rushed forward and loudly asked, startling the maid, who stammered, "

"Just go through the courtyard."

Then this huge group of people rushed over in a flurry.

Kaoru Kazama hung leisurely behind, completely puzzled by the maid's words.

The fact that the car was parked in the back was a special arrangement by the person in charge. If the intention was to leave them nowhere to escape, shouldn't all escape routes have been blocked? Why would they specifically leave a car for them?

Kaoru Kazama had a keen sense of smell. When she reached the courtyard, she already knew that nothing was burning at the back door, which meant that the car parked at the back door was most likely still there.

"Sister Xiaoxun, there really is a car! Quick, let's go over there."

Ran even ran back specifically to pull Kaoru Kazama, who was walking behind, to the back door.

It was a small sedan, a rather old-fashioned model, but it had escaped the wreckage of those luxury cars and was now the only means of transportation in this remote mountain villa.

Although the suspension bridge has been destroyed, having a vehicle is still much safer and more convenient than walking alone.

The detectives then planned to drive the car to check if the suspension bridge had really been destroyed, but a problem arose in the selection of personnel.

Hakuba Saguru, Mogi Harufumi, Gunta Ikumi, Uncle Mori, and Ms. Senma were all going, but the car only had four seats, so Conan took out five coins from his wallet.

The sound of the crashing things around made Kaoru Kazama feel a little sad. This great detective was really too poor. Was it because his living expenses had shrunk after his body shrank?

In island nations, paper money is relatively scarce; most of what circulates are coins, ranging in denomination from five to one thousand, which can be said to meet most of people's daily needs.

On the contrary, banknotes usually have larger denominations, such as 1,000 Natsume Soseki and 10,000 Fukuzawa Yukichi. Even with inflation in the island nation and the relatively low value of the currency, spending 10,000 yen at a time is still considered a luxury.

Kazama Kaoru actually wanted to explore the other parts of this Twilight Villa. Obviously, since the system had issued the mission to find clues about the Black Organization, it meant that there must be something here that was related to the Black Organization.

Even the wealthy Karasuma Renya from half a century ago was not unrelated to the Black Organization.

Before he transmigrated, there were indeed various speculations online about the boss of the dark organization.

There's also speculation about the drug aptx-4869. Logically, the Dark Organization wouldn't spend so much manpower and resources just to research a drug that causes natural death. Even if the Dark Organization double-crosses each other, they wouldn't poison people every time.

Putting everything else aside, what if our own people take it and there's no antidote? Then we might all be wiped out one day.

"Ai, come with me later."

What are you going to do?

Ai was watching the detectives guess heads or tails of a coin game with their arms crossed. They were taking this childish game so seriously; it was truly impressive how serious these detectives were.

"It's nothing, I just made a discovery and I'm planning to go and take a look."

"I'm going back to my room now. I'll wait for your good news."

After saying that, Kaoru Kazama pulled Ai back to their room, leaving the detectives behind. Their eyes darted around, each with a hint of something unsettling.

"What are you doing back here? Did you figure out the code?"

"Not yet, but let me change my clothes first, then I'll take you on an adventure."

Kazama Kaoru noticed the mission notification flashing when he walked through a room earlier, so he had been itching to take action himself.

To be honest, this Xianyu system is pretty good for me. Although it's not very reliable, it's still very convenient.

Just now, as I walked through a room, the main quest message suddenly started flashing in my mind, indicating that there were relevant clues there.

That's why he came back at this time. First, to find out the clue, and second, to change into a cosplay outfit and see what the code really meant.

After all, the purpose of this trip was to teach the detective a lesson, and if they just slack off the whole time, it wouldn't look good when they went back.

With that in mind, Kaoru Kazama took out Kyoko Kirigiri's outfit directly from the system space.

This beautiful young detective is known for her calm demeanor and strong information processing ability. Moreover, she was born into a family of detectives, meaning that her ancestors were detectives for generations. She even has a famous detective father, compared to her grandfather Kindaichi.

"Hey, look here."

The sound Ai made drew Kaoru Kazama's attention. He went over and saw that Ai was pointing at the piano.

Between two white piano keys, there was a piece of yellow paper.

However, only a pointed corner is visible, and since it's sandwiched inside the piano keys, you really can't notice it unless you look closely.
