In Conan, people have a brain option system

"Sister Yoko, do you know something about my mother's murderer?"

Akikawa Kyousuke looked at Okino Yoko and asked directly.

"I don't know."

Then Akikawa Kyousuke saw a confused look on Okino Yoko's pretty cheeks and shook his head towards him.

"Then why doesn't my sister want me to be an artist?"

"Because I know that the artist industry is very deep, and everyone is just maintaining a harmonious relationship on the surface."

Okino Yoko replied.

"Just like when we were at the Imperial Theater before, Xiaokong, maybe you feel that you didn't do anything to Mr. Saihara, but you were jealous and resentful by Mr. Saihara."

"Including when I was an idol in the Earth Lady team, I have been in the Japanese entertainment industry for seven years."

"There are countless intrigues and intrigues encountered during this period, so I don't want Xiao Kongyou to experience these things."

Okino Yoko has a sincere expression and sincere tone.

The words are also very convincing.

However, Akikawa Kousuke knew that Okino Yoko was not telling the truth.

This is not because Akikawa Kyusuke noticed the clues from Okino Yoko's micro-expression.

It was simply because he was certain that Okino Yoko knew the inside story of the car accident through Okino Yoko's absence from the filming last year and her persuasion not to become an artist today.

'This woman...'

Akikawa Kyusuke just grabbed Okino Yoko's hand, not just because he wanted to judge her inner emotions at the moment by feeling the temperature of Okino Yoko's palm.

He also has another purpose, which is to detect lies.

Although Okino Yoko is holding Akikawa Kyusuke's hand with both hands at this moment.

But what Okino Yoko didn't notice was that Akikawa Kyusuke's middle finger was always placed on her radial artery.

This is the most common location for measuring your pulse, located on the inside of your wrist near your thumb.

Compared with lie detectors that rely on detecting changes in physiological indicators such as target heart rate, blood pressure, respiratory rate, and galvanic skin response to detect lies,

Using pulse to detect lies is not that reliable.

However, in the current crude environment, this is one of the few means Akikawa Kongsuke can rely on.

The human body's pulse beat can reflect the target's psychological changes in real time.

When a person lies, he or she may feel nervous or anxious.

This can cause the heart rate to increase, causing the pulse to become irregular or briefly accelerated.

Some people may feel uneasy when lying, causing slight tremors in the body, which can also affect the stability of the pulse.

However, when Kyusuke Akikawa was surprised, Yoko Okino's pulse beat did not show any disorder at all when she said what she just said.

This shows that Okino Yoko can lie without blushing or heartbeat.

Although in the eyes of most people, people like idols and entertainers are a collection of countless lies.

But there are very few artists who can avoid physiological reactions.

In addition, Akikawa Kyusuke is not sure whether it is a coincidence.

Okino Yoko's answer to her question is exactly in line with the "half-truth strategy" in counter-reconnaissance techniques.

A method of admitting the truth to some extent in order to remain physiologically stable and avoid polygraph detection.

This is much more clever than Toda Kyouji and others directly lying to deceive themselves.

Whether Okino Yoko did it deliberately or was able to achieve this level unconsciously,

It all means that this woman is not simple.

'She is deliberately hiding the car accident case from me. It seems that simply asking her will not tell me the truth. ’

Although Akikawa Kyusuke was not able to get information about the real culprit of the car accident from Okino Yoko.

But Akikawa Kyusuke is not completely without gains.

At least Akikawa Kongsuke is sure.

Okino Yoko has absolutely no connection with the original owner and the original owner's mother, as investigated by the Metropolitan Police Department.

‘Yoko Okino’s concern for me is not false, so she shouldn’t be the murderer either. ’

'If she was trying to save "me" from "mother", she shouldn't have left such obvious clues that would make "me" a suspect. ’

'At least she probably didn't know that "I" had prepared sleeping pills in advance. ’

At this moment, the possibility that Okino Yoko was the murderer or the person behind the scenes was also ruled out.

But because of this, new questions arose in Akikawa Kongsuke's mind.

That is, what was the murderer’s motive for killing Ryoko Akikawa?

‘According to the current information, the only benefits that Ryoko Akikawa can provide after her death, apart from allowing me to regain my freedom, are the two life insurances and the self-indemnity insurance. ’

‘But until now, I haven’t seen anyone coveting this insurance money. ’

The beneficiary of Akikawa Ryoko's insurance is himself, and the beneficiary of his own insurance is Akikawa Ryoko.

The original owner's father had already passed away.

Akikawa Kyousuke also ruled out the possibility that the original owner killed his mother.

The final beneficiary is Okino Yoko.

But the key point is that Okino Yoko, as the most top star in Japan today, does not lack the insurance money of a mere 100 million yen.

Then the possibility of the murderer killing for insurance money is also blocked.

‘So, Akikawa Ryoko had made enemies with someone in the past, and she took her son to move around and change her residence frequently, just to avoid her enemies…’

Akikawa Sosuke felt a little headache because of the lack of information.

If Akikawa Ryoko really had made enemies with someone in the past, then the difficulty of investigating would increase exponentially without the original owner's memory.

Due to Okino Yoko's concealment, Akikawa Sosuke felt that the truth behind the car accident was a little unusual.

‘Speaking of which, is Okino Yoko's judgment necessarily accurate? ’

‘As long as you don't become an artist, you can avoid danger? ’

With all kinds of doubts, Akikawa Sosuke pulled his hand out of Okino Yoko's hand.

“Sorry, Sister Yoko, I still think that my life now is much more interesting than before.”

Akikawa Sosuke saw that after hearing what he said, Okino Yoko showed an extremely tangled expression again.

After a moment, Okino Yoko nodded as if she had made up her mind.

‘It seems that it has little to do with the identity of an “entertainer.” ’

Akikawa Sosuke thought to himself, and then thanked Okino Yoko:

“Thank you.”

Hearing Akikawa Sosuke’s thanks, Okino Yoko also showed a slightly helpless smile.

This look is like a mother who couldn’t resist her child, and finally agreed to her child’s willful request after a huge psychological struggle.

“Come to think of it, why didn’t I see Miss Itakura?”

“In the morning, it was me who asked her to go to see your stage activities, Sister Yoko.”

Akikawa Sosuke said with a confused look on his face.

After hearing Akikawa Sosuke’s words, Okino Yoko showed an extremely embarrassed expression and looked away for a moment.
