"Is this dog the wrong person?"

"I am Sayuri's husband, and today is my wedding with her. How could I poison and kill my own wife at my own wedding?"

"Everyone here knows me and Sayuri... You should all know that I have always had a very good relationship with her!"

His self-defense made the surprise in everyone's eyes turn into doubt again.

Even Matsumoto, who was already furious, couldn't help being stunned:

"That's right... Takasugi, you have no reason to kill Sayuri at all."

"Is it really a mistake?"

Police Matsumoto turned his head and looked at Caesar in confusion.

Dogs certainly couldn't answer his questions.

It just stared at Takasugi Toshihiko, barking barkingly.

"The accuracy of smell source identification is indeed not [-]%."

"But at least it gives us a direction to investigate."

"Matsumoto police officer, let's not be preconceived and give up suspicion so quickly."

Lin Xinyi said calmly.

"This..." Police Matsumoto's expression froze.

He is also an old policeman, and he has also investigated and handled many cases where husband and wife turned against each other.

Those cases and experiences told him that many couples who look loving in the eyes of others may have developed to the point of incompatibility behind their backs.

Therefore, we should not simply give up suspicion just because we have found out that the suspect and the victim are "loving" and cannot find the motive for the time being.

but…

"But this is my daughter...I know my daughter."

"She said she loved Takasugi and said she wanted to be Takasugi's wife."

Recalling his daughter's happy appearance in her wedding dress, Matsumoto's expression was a little dazed:

"The look in her eyes when she talks can't be fooled."

"I know Sayuri is very happy... I know Takasugi must be very kind to her."

"That's why I'm willing to marry my daughter to him."

"So... Takasugi, you can't kill Sayuri, right?"

"Mmm...mm." Takasugi Toshihiko nodded hastily, but there was an imperceptible trace of guilt in his eyes.

Lin Xinyi did not capture such subtle emotions.

But he is different from Matsumoto who is in the bureau, he will not give up his suspicion easily because of this so-called emotion.

Therefore, no matter how loving the groom claims to be with the victim, Lin Xinyi will continue to investigate step by step:

"Mr. Takasugi Toshihiko, have you been to this dressing room?"

"I..." Takasugi Toshihiko thought for a while, and said, "I came to the dressing room and chatted with Sayuri alone for a while."

"But that was about 3 minutes before Sayuri was poisoned and fell down."

"Except for that one time, I have been entertaining guests outside for half an hour, and everyone can see that."

"And that capsule... yeah, didn't you find a mostly half-melted capsule in your lemon tea?"

As if he had found some key evidence, his voice gained confidence:

"Isn't the poison contained in this capsule?"

"That capsule has to dissolve most of it, 3 minutes must not be enough?"

"In this case, I, who only came to the dressing room 3 minutes before the incident, must not be the murderer!"

Takasugi Toshihiko was ingenious and used the melting time of the capsule to rule out his suspicion.

Upon hearing this, Mumu Police Department and others felt that what he said was very reasonable.

But Lin Xinyi's expression became weird instead:

"I see, why did the murderer put a capsule in it?"

"Co-authorship is used to create an alibi for yourself."

When he said this, Mr. Takasugi's expression suddenly changed.

And Lin Xinyi just continued:

"Although incompletely dissolved capsules were found in the drink, this does not mean that the poison must have been contained in the capsules."

"There are indeed medicinal sodium hydroxide capsules for sale on the market. Maybe the murderer just wants us to think that he used this capsule-style sodium hydroxide to poison."

"If we really believe it, the time it takes for the capsule to dissolve can help rule him out."

"but…"

"The murderer's level of knowledge is too urgent."

Lin Xinyi sighed helplessly:

"While poisoning, he only put a disguised capsule in the drink."

"The capacity of this can of lemon tea is 350ml. From what we saw after the incident, the amount of tea left in the can and spilled on the floor was at least 200ml by visual inspection."

"And the amount of medicine contained in a medicinal capsule is about 0.5g..."

"0.5g of sodium hydroxide is put into at least 200g of lemon tea."

"The citric acid in lemon tea alone is probably enough to neutralize such a little sodium hydroxide."

Lin Xinyi shook his head, looking at Takasugi Toshihiko as if looking at a fool:

"A sodium hydroxide solution of this concentration..."

"Hmm...if there was any sodium hydroxide left in that solution that wasn't neutralized by the citric acid, it could be called a 'sodium hydroxide solution'..."

"Don't say it can burn the respiratory tract, it's okay to drink it as water."

Chapter 218 The question of the soul

The sodium hydroxide solution does burn the throat.

But that also depends on concentration.

The concentration is low, let alone poisoning people...

Let's just say that the kind of body lubricant used in certain sensitive parts contains sodium hydroxide to thicken and lubricate.

This ultra-low concentration sodium hydroxide solution is completely harmless and cannot burn human mucous membranes at all.

And under Lin Xinyi's simple explanation...

You don't need to have studied junior high school chemistry or primary school mathematics, all the guests present will know how unreliable this trick used to create an alibi is.

"That is to say..." Everyone responded.

Especially Matsumoto Police Officer, his gaze at his son-in-law quietly became fierce:

"The dissolution time of the capsule means nothing at all, and Takasugi's alibi is completely invalid?"

"That's right..."

Lin Xin nodded and added:

"If I'm not mistaken, the murderer must have put the half-dissolved capsule and a large amount of sodium hydroxide into the can of lemon tea."

"According to his thinking, when we saw the capsule, we would subconsciously think that he was poisoning with capsule-style sodium hydroxide."

"Theoretically, this method can play a certain role, but..."

Speaking of this, Lin Xinyi himself felt a little embarrassed.

He just thought for a full 10 minutes, but he didn't think why the murderer put such a capsule in the lemon tea.

I didn't expect it, I really didn't expect it...

The murderer put such a capsule because he was stupid.

"If you want to use capsules to confuse the public and mislead the investigation, you should put more capsules!"

"There's only one capsule, just this bit of sodium hydroxide. Is this intended to treat people with hyperacidity?"

Hearing this mocking exclamation, the groom's official Takasugi Toshihiko's face turned red and then turned pale.

It looked not only guilty, but also extremely funny.

"Mr. Gao Sugi, you said that you came to the dressing room 3 minutes before the incident?" Lin Xinyi asked calmly.

"Hmm..." Takasugi Toshihiko nodded stiffly.

"That's right."

Lin Xinyi's gaze suddenly became sharp:

"When Miss Maori and I rushed over to investigate, the can of lemon tea was still hot!"

"And when I saw Miss Sayuri drinking lemon tea, it was obviously cold."

"Her lemon tea is obviously warm because the murderer put too much sodium hydroxide in it. Sodium hydroxide dissolves in water and releases a lot of heat!"

"And this warm lemon tea didn't even have time to cool down, Miss Sayuri collapsed from shock."

"This shows that when the murderer poisoned her, it was just a few minutes before she drank the poisoned drink."

"Mr. Takasugi Toshihiko—"

"You, who only visited the dressing room three minutes before the incident, are undoubtedly the biggest suspect in this case."

"I...I..." Takasugi Toshihiko became a little incoherent.

He was no longer as calm as before, and panic was written on his face.
