Chapter 568: Solving the case depends on science and science fiction

"I see."

All the famous detectives here finally understood the secret of Lin Xinyi’s ability to uncover the murderer’s conspiracy ahead of his peers:

"It turns out it's because of your special physique, Mr. Lin."

"I am naturally sensitive to potassium cyanide!"

Lin Xinyi: "I"

Do I have a special constitution? ?

He subconsciously wanted to say something.

But think about it and forget it——

If he is the only normal person in the world, then he is not normal.

"As expected of a man who can lift a car." Motegi Haruhi suddenly sighed: "Is it because of years of practicing martial arts that your perception has become sharper than normal people?"

"Hey? Is that so?" Mao Lilan looked over cutely: "Mr. Lin."

"It turns out that you have already reached a state that I can't understand at all!"

"." Now Lin Xinyi was speechless.

Well, he seems to be abnormal to begin with.

Does a guy who can lift a car have the right to complain about other people's ruthless iron hands?

"Yes, I just have a special physique."

Lin Xinyi explained the past vaguely.

Seeing everyone washing their fingers with mineral water, he tried to bring the topic back to the main topic with the complicated emotions that had not yet calmed down:

"Grandma Qianjian, it's time to talk about your situation."

"Detective Ogami accuses you of conspiring with him, suspected of illegal possession of explosives, illegal detention, explosion crimes, and additionally suspected of releasing dangerous substances to endanger the lives of many people, and attempted intentional homicide."

"Do you have anything to say about these accusations?"

With so many crimes put together, if they are all brought to light

Qian Jian's mother-in-law will probably run into a community to cook barley for the rest of her life, and live a good life with free medical care, free housing, and state-funded retirement care.

This welfare package is so reliable that it makes people want to go to prison just by looking at it.

But Qianjian Jiangdai chose to refuse:

"I've said everything that needs to be said."

"I had no prior knowledge of Mr. Ogami's sinister accusations."

"As for the poisoning, who can guarantee that it was not Mr. Zhu Shan's own handiwork?"

Qianjian Jiangdai took the blame for poisoning and killing Dashang Zhushan back on Dashang Zhushan himself:

"Maybe he originally wanted to use the potassium cyanide against us detectives."

"But because Mr. Lin, you just exposed his conspiracy, which made him temporarily turbulent and despairing, so he was so excited that he wanted to bite his nails and kill himself."

"After being unexpectedly stopped by Mr. Lin, he instantly lost the courage to commit suicide. When he heard that Mr. Lin speculated that 'he has an accomplice,' he had an idea and used the opportunity to drag me down -"

"Just think about it"

"As long as he can have one more 'accomplice' like me and put the most serious charges of poisoning and murder on my head, his own sentence can be reduced a lot."

"That makes perfect sense in terms of motivation, doesn't it?"

Qianjian Shengdai's subjective but logical explanation actually put the blame on himself.

"You?!" Senior Zhu Shan's fat face twitched with anger:

He didn't expect that his accomplice was even thicker-skinned than him.

He, the main culprit, personally came forward to accuse him, yet the other party dared to make up such a nonsense reason!

"Absurd! Ridiculous!"

"I have never seen such shamelessness"

Zhu Shanzheng, the superior, yelled and cursed angrily, but Qianjian Jiandai interrupted his chanting unhurriedly:

"It's not up to you or me to judge whether it's ridiculous or not."

"That's the judge's job."

"If you can't produce reliable evidence, then wait until you go to court and talk to my lawyer!"

The elder Zhu Shan choked hard at these words.

Lin Xinyi also felt bad:

Indeed, although the speculation given by Qian Jianjiangdai that "the great leader Zhu Shan put part of the blame on others in order to alleviate his own crimes" is obviously outrageous.

But without enough reliable evidence, there is no way to falsify her statement or prove that she committed a crime.

This is somewhat of a forced quibble.

If an ordinary person were to face the strong accusations made by the main culprit, Dashang Zhushan, such sophistry would not have much effect.

But the worst thing is that Qian Jian's words also revealed that she has the capital to quibble——

She is not a poor ghost like Da Shang Zhu Shan.

She still has money, very rich, and enough money to hire the best lawyers in Japan to defend her.

"Now we're in trouble"

Lin Xinyi frowned slightly.

He thought for a while, turned to his superior Zhu Shan and asked:

"Mr. Ogami, you said Senjian Yudai is your accomplice, so don't you have any evidence that she conspired with you to commit the crime?"

"I", the great leader Zhu Shan, was speechless for a moment:

He indeed conspired with Senjian Yudai to plan many things.

However, when they discussed their criminal plans, they did not leave meeting minutes. They also contacted each other through phone calls and did not leave any text messages, such as text messages or emails, that could be traced.

In addition, he is the principal criminal, and Senjian Yudai is just an accomplice who assists him.

He was responsible for purchasing real estate, preparing bombs, sending invitations, and even detonating the bomb just now.

Now think about it carefully.

Senjian Yoyo completely removed himself from this incident, leaving no trace behind.

In the end, Dashang Zhushan could only give such a helpless answer:

"I don't have any evidence."

So where to find evidence?

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

"Speaking of which, Granny Qianjian did have some abnormalities before."

Motegi Harushi suddenly said thoughtfully:

"When she sees each of us, she will deliberately emphasize that she has a headache, a cough, and feels unwell today, and she cannot smell the smoke at all."

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

"But now that I think about it, she did it because she put potassium cyanide on the outside of all the teacups."

"If any of us touches the cigarette butt with his finger while smoking, he may be poisoned by potassium cyanide before Da Shang Zhu Shan, ruining her plan to kill Da Shang Zhu Shan."

Motegi Haruka carefully analyzed the strange behavior of Senjian before he was demoted.

The famous detectives all nodded secretly.

This makes Qianjian’s downgraded expression somewhat subtle:

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

This means that even if Lin Xinyi does not come forward to stop her, her carefully designed murder method will soon be seen through by these famous detectives.

It seems that her decision this time was really wrong.

Qianjian Jiandao couldn't help but feel a trace of regret in his heart.

But on the surface, she still maintained her stubborn composure:

"What a good reasoning."

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

"I do have a headache and cough today, so I simply don't want to smell the smoke. Isn't that okay?"

"." Motegi Haruhi also turned off his fire when asked.

There is no way. Without evidence, no matter how wonderful the reasoning is, it is useless.

Now, both Ojoshu Zen and Motegi Haruka, two famous detectives, have been defeated by Senjian Shidai.

No one seemed to be able to do anything to her.

And in this silence, I saw Gunda Ikumi looking over quietly:

"Detective Senjian, you are right."

"I have also observed carefully as a doctor. The headache and cough you have today are all real."

"So, here's the problem"

Gunda Ikumi unleashed her ultimate move.

This trick is not a trick from a famous detective, but a trick from a forensic doctor that Lin Xinyi feels very close to:

"Detective Senjian, when did you start having headaches and coughing?"

"Is it yesterday, today, or after applying potassium cyanide on the tea cup?"

"Huh?" Senjian Jiashiro frowned slightly, a trace of surprise flashed in his eyes: "Miss Gunda, what do you want to say?"

"Don't get excited, I just want to tell you some simple scientific knowledge:"

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

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

"Potassium cyanide will deliquesce in humid air and react with water and carbon dioxide to release trace amounts of hydrogen cyanide gas."

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

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

Detectives like to smell the bitter almond smell directly.

In fact, you are smelling poisonous gas.

It's okay if you smell it for a while, but if you smell it for a long time, it will make you sick.

"It would take a lot of time to coat so many teacups with potassium cyanide powder."

"I think Detective Qianjian, when you applied potassium cyanide powder to the tea cup, you probably didn't strictly abide by the laboratory safety regulations and wear an isolation respirator, right?"

"If not, then."

Gunda Ikumi stared over with burning eyes:

"You are breathing in the hydrogen cyanide gas generated by the deterioration of potassium cyanide in humid air, or you may even inhale potassium cyanide dust."

"It must have been mild cyanide poisoning."

"Respiratory mucosal irritation, increased nasal discharge, cough, dizziness, and headache are all symptoms of mild cyanide poisoning!"

"In that case."

Gunda Ikumi turned to look at Lin Xinyi again:

"Mr. Lin, I suggest you open the forensic investigation box now, take the blood sample of Detective Qianjian and bring it back to the Department of Science and Technology for toxicology analysis."

"If her blood cyanide concentration is significantly higher than ours, that would explain some problems."

Everyone was dipped in potassium cyanide powder.

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

This indeed indirectly proves that Senma Yoyo was exposed to cyanide earlier and for a longer period of time than anyone else present.

Gunada Ikumi's idea is correct.

Lin Xinyi also secretly praised the senior forensic doctor's idea.

But

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

Senjian Shidai was only slightly flustered, and then quickly regained his composure:

"I only had a cough and headache because of a cold. It was not because of any prior exposure to cyanide that led to mild cyanide poisoning."

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

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

"And I just drank several sips of tea. When I drank the tea, I had difficulty breathing due to a cold, so I inhaled harder. Maybe it was at this time that I inhaled more potassium cyanide dust than others?"

"So even if my blood cyanide concentration is higher than everyone else, it's normal."

"You" Gunda Ikumi was speechless.

She knew that the other party was probably making excuses.

But when I think about it carefully, I have to admit that there is almost no solution to the loophole that the other party found.

In the final analysis, her reasoning process was not rigorous enough to rule out the possibility raised by Senjian Fengdai.

The air became stagnant again.

All three detectives were defeated.

The tricks of friend confession, detective reasoning, and forensic examination were also used, and the opponent's defense was still so impeccable.

"Let me try."

Lin Xinyi finally stood up.

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

The forensic doctor's tricks have already been used by Gunda Ikumi.

What new ideas can Lin Xinyi come up with?

Although he knew that the other party was hunting him, as a famous detective, Senjian Fangshi couldn't help but feel a little curious.

Conan and others also looked over expectantly.

At this time, Lin Xinyi pulled out his chair and slowly sat across from Senjian Yoyo.

But the first question he asked was not Qianjian Descendant, but Dashang Zhushan.

"Mr. Ogami."

"Are you the first one to arrive at the Dusk Pavilion today?"

"Yes." Dashang Zhushan explained honestly: "I arrived at the Dusk Pavilion in advance at 4 o'clock in the afternoon to prepare for the evening operation."

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

"Uh this"

The superior 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 tableware on the dining table. I just thought they were arranged by the maid I hired."

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

The maid was still immersed in today's shocking experience. It was not until she was reminded by Lin Xinyi that she answered calmly:

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

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

"I understand." Lin Xin nodded:

The teacup stained with poison had been arranged in advance.

And because after four o'clock in the afternoon, there were always people in the Twilight Hall who were unable to move around, so the murderer could only arrange the poisonous tea cup before four o'clock in the afternoon.

"So, Detective Senjian"

"Before 4 o'clock this afternoon, where were you and what were you doing? Can anyone prove it to you?"

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

Lin Xinyi asked several questions in a row, and his momentum was quite scary.

But Senjian Fangdai laughed easily:

It turns out that this is Lin Xinyi's strategy.

Forensic methods didn't work, so the police resorted to stupid methods.

It is nothing more than constantly asking the suspect to answer questions through interrogation, describe in detail his experience during the time of the crime, and then try to find loopholes in the details.

If the suspect is the real murderer, then the experiences described in his testimony can only be fabricated.

Since it was fabricated, it is theoretically possible for the police to discover flaws in his testimony.

If there is a contradiction between the testimony and the facts and it is determined to be a forged testimony, then this can become a powerful criminal evidence in court.

"It's a good idea."

"But... is it really that easy to find loopholes in my testimony?"

If such a stupid method can be used everywhere, why would a detective be needed?

Qianjian Jiandao smiled helplessly in his heart.

Then he organized his words again and answered carefully:

"Mr. Lin, you don't know when I came to the Dusk Pavilion."

"It was around 6 p.m., and you drove me here when the car broke down halfway, right?"

There is only one way to the Dusk Pavilion.

The first one to arrive was Ogami Shuzen, followed by the maid lady, Gunda Ikumi, and Motegi Haruka.

Motegi Haruka didn't encounter Senma Yoyo, whose car broke down on the way here.

The Senjian demotion could only be driven on this mountain road after Motegi Haruka and before Lin Xinyi arrived, that is, around 6 p.m.

This was an established fact and she couldn't change it.

Therefore, Qianjian’s descent can only be explained according to this situation:

"I drove to this mountainous area around 6 p.m."

"As a result, the car broke down halfway before reaching the Twilight Pavilion."

"As for before 4 p.m."

"I should still be at home."

Qianjian Shengdai explained unhurriedly:

"I have a villa in the countryside of Tottori Prefecture, about forty minutes' drive from here."

"Because the drive was so short, I didn't go to a store, a gas station, or anyone else saw me along the way."

"And I usually live alone, so no one can prove it during the time I was at home."

No one can prove that she was at home at that time.

That is, no one can prove that she was not at home at that time.

The experience fabricated by Senjian Yudai seems vague and suspicious, but in fact it is the most troublesome for the police.

There was no one else in this whole story except her, and Lin Xinyi couldn't find out even if he wanted to.

And the roads in this world are unsafe and monitored.

She walked along sparsely populated rural roads throughout the journey.

No one knows at all when she drove away from home and when she arrived in the mountainous area where the Twilight Pavilion is located.

Senjian Yushiro felt that he was very stable.

That's what she was thinking.

But suddenly I heard Lin Xinyi ask:

"Detective Qianjian, when you came here early in the afternoon to apply poison on the teacup, did you have your mobile phone with you?"

"Huh?" Qianjian Fangdai was slightly startled.

"Is your phone on?"

"." Qian Jianjiangdai had a bad premonition in his heart.

"Looks like it's turned on."

Lin Xinyi smiled:

"The Twilight Pavilion is indeed outside the coverage of mobile phone signals."

"But the only mountain road that comes here from the outside world, there is still a section of the road that has signal coverage."

"If you turn on your mobile phone and drive here, your mobile phone number will automatically make a handshake connection with the local base station."

"There will be a registration record of your mobile phone number on the local base station."

"This record includes the time you appeared in this mountainous area."

"Do you understand, Detective Senjian?"

The mobile phone number can be used to check the historical movement trajectory. This is something that everyone who has experienced epidemic prevention and control knows.

Senjian Yuishi said that she was still at home at 4 o'clock in the afternoon.

But as long as she checked the mobile phone number registration record of the base station, she would know which base station she was within the range at that time.

"I recorded everything I just said."

Lin Xinyi took out the voice recorder hidden in his pocket and said with a smile:

"All the detectives here can also be witnesses."

"Grandma Qianjian, if the base station registration record shows that your location at that time is inconsistent with your testimony, then you will have nothing to explain."

"You" Qianjian Shengdai's face darkened:

"Stop joking, Mr. Lin."

"The communication system can only grasp the LAC location area code and base station number of the mobile phone in real time, and will not record historical information."

"As long as no calls are made, no text messages are sent, and no bill is generated, the operator will not record the user's historical movement track."

After all, she is also a famous detective living in the technological age.

Although he may not have studied in Hawaii, he can be said to be well-read.

If you use this bit of communication knowledge to fool people, who are you looking down on?

"Ha, it turns out you understand."

"No wonder you are so brave to make it up."

Faced with Qianjian's calmness, Lin Xin showed no sign of timidity.

So what if she understands modern science?

What he understands is future science fiction.

"Sorry, Detective Senjian."

"You are right, the base station can only be used for real-time positioning and will not save historical registration records."

"but."

However, operators can collect and store this real-time information through third-party systems.

Because in the future big data era, these user data are valuable treasures to be mined.

Although I don’t know if there is such a real-time data collection system now.

but.

"I do." Lin Xinyi spread his hands:

"After receiving the invitation from the Twilight Pavilion, that was two days ago."

"I asked a 'friend' to cooperate with the communication operator to secretly monitor all the signal base stations closest to the Dusk Pavilion."

The friend naturally refers to artificial intelligence Noah’s Ark.

As for the operator, this communication company is run by Suzuki Sonoko's family.

With such strong connections and such sci-fi technology, wouldn’t it be easy to collect real-time registration information of several base stations?

"That is to say."

"Who has been here in the past two days and when did they come."

"As long as he has his phone with him, I have a record on my hand."
