Coroner Coroner

"I... I don't have any evidence."

Where should I find evidence?

The scene was silent, and everyone was lost in thought.

"Speaking of which, Granny Qianjian was indeed a little abnormal before."

Motegi Haruki suddenly said thoughtfully:

"When she saw each of us, she would deliberately emphasize that she had a headache, cough, and was not feeling well today, and she couldn't smell the smell of smoke at all."

"I thought she just didn't like us smoking in front of her."

"But thinking about it now, she did it because she painted potassium cyanide on the outside of all the teacups."

"If anyone of us touches a cigarette butt while smoking, he may be poisoned to death by potassium cyanide before Dashang Zhushan, destroying her plan to kill Dashang Zhushan."

Motegi Haruki carefully analyzed the strange performance of Qianjian Jiangdai before.

The famous detectives also nodded secretly.

This made Qianjian's expression a bit subtle:

It turns out that everyone has noticed these strange things about her for a long time.

This means that even if Lin Xinyi didn't come forward to stop her, her well-designed killing methods would be quickly seen through by these famous detectives.

It seems that her decision this time was really wrong...

Qianjian Jiangdai couldn't help feeling a trace of regret in his heart.

But on the surface, she still maintained that stubborn composure to the end:

"That's a good reasoning."

"But don't forget, Mogi, this reasoning is just reasoning, not evidence."

"I do have some headaches and coughs today, so I simply don't want to smell the smoke, isn't that okay?"

"..." Mogi Haruki was also asked to turn off the fire.

No way... Without evidence, no matter how brilliant the reasoning is, it's useless.

Now Ogami Zhushan and Mogi Haruki, the two famous detectives are defeated in front of Qianjian Jiangdai.

Everyone seemed to have nothing to do with her.

And in this silence, only gun Tian Yumei looked over quietly:

"Detective Qianjian, you are right."

"I have also carefully observed it as a doctor. Your headache and cough symptoms today are all real."

"So, here comes the problem..."

Gun Tian Yumi unleashed her ultimate move.

This trick is not the trick of a famous detective, but a trick from a forensic doctor that makes Lin Xinyi quite affectionate:

"Detective Qianjian, since when did you start to have a headache and cough?"

"Was it yesterday, today, or...after the potassium cyanide was applied to the teacup?"

"Huh?" Qianjian Jiangdai frowned slightly, and a trace of surprise flashed in his eyes: "Miss Guntian, what do you want to say?"

"Don't get excited, I'm just going to tell you some simple science:"

Although Gunta Ikumi has not been a forensic doctor for many years, those knowledge reserves are still there:

"It has been raining in Tottori Prefecture today, and the air humidity is high."

"And potassium cyanide will deliquesce in humid air and react with water and carbon dioxide to release a trace amount of hydrogen cyanide gas."

"This hydrogen cyanide gas is also a highly toxic substance. It was used by the Germans as a murder gas in the gas chambers during World War II."

"And it... is actually what we usually smell in the mouth of people with cyanide poisoning, the so-called 'bitter almond' smell."

Detectives like to smell the bitter almonds directly.

In fact, it is smelling poisonous gas.

It's okay to smell it for a while, but after a long time, it's going to be on the head.

"It would not take too long to coat so many teacups with potassium cyanide powder."

"I think Detective Qianjian, when you smeared potassium cyanide powder on the teacup, you probably didn't strictly abide by the laboratory safety protection regulations and wear an isolation respirator, right?"

"If not, then..."

Guntian Yumi stared at her with burning eyes:

"Breathing the hydrogen cyanide gas produced by the deterioration of potassium cyanide in humid air, you may even inhale the potassium cyanide dust..."

"Should have been mild cyanide poisoning."

"Respiratory mucosal irritation, coughing, increased nasal mucus, and headache are all symptoms of mild cyanide poisoning!"

"In that case..."

Guntian Ikumi turned to look at Lin Xinyi again:

"Mr. Lin, I suggest you open the forensic investigation box right now, and take the blood samples of Qianjian detectives back to Kesouyan for toxicological analysis."

"If her blood cyanide concentration is obviously higher than that of us, it can explain some problems."

Everyone was dipped in potassium cyanide powder.

But she was the only one who developed symptoms of cyanide poisoning, and this symptom occurred before everyone was exposed to potassium cyanide.

This can indeed indirectly prove that Qianjian Xiadai was exposed to cyanide earlier and longer than other people present.

Guntian Ikumi's thinking is correct.

Lin Xinyi also secretly wondered what this senior forensic doctor thought.

but…

"Miss Guntian, you are not being strict when you say that."

Qianjian Jiangdai was only a little flustered, and then quickly regained his composure:

"I only coughed and had a headache because of a cold and a cold, not because of any prior exposure to cyanide, which led to mild cyanide poisoning."

"As for the fact that my blood cyanide levels may be higher than other people's..."

"Don't forget, people's physiques cannot be generalized."

"And I just drank a few sips of tea. When I drank the tea, I couldn't breathe well due to a cold, and I inhaled harder—maybe it was at this time that I inhaled more potassium cyanide dust than others?"

"So even though my blood cyanide levels are higher than everyone else's, it's normal."

"You..." Guntian Yumi was stunned speechless.

She knew that the other party was mostly quibbling.

But after thinking about it carefully, I have to admit that the loophole found by the other party is almost unsolvable.

In the final analysis, her reasoning process was not rigorous enough to rule out the possibility proposed by Qianjian Jiangdai.

The air froze again.

All three detectives were defeated.

Accomplice confession, detective reasoning, and forensic examination techniques were all used, and the opponent was still so impeccable.

"Let me try."

Lin Xinyi finally stood up.

"Oh?" Qianjian Jiangdai looked at him with some concern:

The forensic trick has already been used by Guntian Ikumi.

What new ideas can Lin Xinyi come up with?

Although he knew that the other party was chasing him, as a famous detective, Qianjian Jiangdai couldn't help but feel a little curious.

Conan and the others also looked over expectantly.

At this time, I saw Lin Xinyi pulling out the chair and slowly sitting opposite Qianjian Jiangdai.

But the first question he asked was not Qian Jian's generation, but Da Shang's wish.

"Mr. Osami."

"Are you the first to arrive at the Twilight Pavilion today?"

"Yes." Dashang Zhushan honestly confessed: "I arrived at the Twilight Pavilion ahead of time at 4 p.m. to prepare for the night's action."

"Then when you came, were the teacups on the table already arranged?"

"Uh...this..."

Da Shang Zhu Shan frowned slightly:

"Because I was busy preparing explosives, I didn't pay attention to the situation in the restaurant."

"I just saw the teacups and cutlery on the dining table, and I thought they were arranged by the maid I hired."

As he spoke, he looked at the maid lady thoughtfully.

And the maid lady was still immersed in today's shocking experience, until she was reminded by Lin Xinyi, she answered dumbly:

"No, I didn't arrange the tea set."

"When I came, the dishes on the table had already been set."

"Understood." Lin Xin nodded:

The poisonous teacup was arranged in advance.

And because after four o'clock in the afternoon, it is always inconvenient for people to move in the Twilight Pavilion, so the time for the murderer to arrange the poisoned tea cup can only be before four o'clock in the afternoon.

"Then, Thousand Detectives..."

"Before 4 o'clock today, where were you and what were you doing, can someone prove it to you?"

"At that time, did you come to the Pavilion of Twilight?"
