"Those droplets are... Tears? ”

Unconsciously, Gray Yuan finally became a little curious about Conan's reasoning.

"This reasoning is indeed very interesting."

"But I always feel that the imagination of your reasoning is a little too rich, Detective..."

"From the lies that Mr. Zhang Tian told in the text message, I came to the conclusion that he was secretly crying at that time, relying on pure imagination."

She unceremoniously pointed out Conan's minor problem of making up too much of his subjective brain.

Then he showed a playful smile at him:

"However, if you can confirm that the droplet is tears, it will support your reasoning even more."

"Uh... What do you mean? ”

Conan vaguely felt that something was wrong.

He felt that Gray Yuan was looking at him at this moment, like looking at a weak and helpless guinea pig.

And Gray Yuan Wai just replied lightly:

"It's too cumbersome to extract those droplets and test them."

"Why don't you go and lick it with your tongue."

"If those droplets are salty, we can immediately confirm that they are Mr. Zhang Tian's tears and not ordinary water."

"......" Conan's little face darkened: "Don't." ”

He decisively rejected the somewhat disgusting offer.

But the curiosity aroused by him was not so easy to stop:

"What are you afraid of... It's just to know the truth as soon as possible. ”

"For the sake of pharmacy research, Sherlock Holmes once asked his friends to taste the taste of plant alkaloids directly with their mouths."

"You should also learn from your idol, Conan."

Gray Plains lamented the scriptures and encouraged Conan to dedicate himself to reasoning.

"No—"

Conan refused with a dark face:

"I have a better way to make sure it's tears than to taste it with my tongue."

"What's the solution?"

Gray Plains was a little curious:

"Do you want to use the flame color reaction to quickly confirm the presence of sodium salts in the water droplets?"

"No, it's not that easy..."

She tried to come up with a solution, but then shook her head and denied herself:

"The flame color reaction test of sodium ions is very troublesome to operate."

"The flame color of sodium is yellow, which can easily coincide with the color of the flame itself, making it difficult to distinguish."

"It is necessary to use a pure and pollution-free blue flame alcohol lamp with a clean wick to ensure the accuracy of the test results."

"If you have the kung fu to go to the laboratory, it is better to directly extract the 'water droplets', use professional methods for laboratory testing, and determine the ingredients."

"What's more, the sodium chloride content in tears is not high, and it is difficult to say whether there can be a visible change in the color of the flame with a few tears."

As he spoke, Gray Plains looked at Conan with a subtle gaze.

As if urging him, quickly lick it with his tongue.

"Don't!"

Conan replied with a tingling scalp:

"I'm not talking about a flame reaction."

"In fact, the method is very simple, just a little reasoning, plus the knowledge of trace analysis."

"First of all, let's say that Mr. Zhang Tian was not crying and answering the phone at that time, but after washing his hands, he stood there ready to commit suicide."

"Then our previous experiments proved that he had to stay still in that position for more than 2 minutes before those few droplets formed."

"And for such a long period of time, under normal circumstances, our hands will maintain a more natural hanging posture with less effort."

"Instead of struggling to raise your hands and hold still for 2 minutes—"

"Even if you keep your hand up, the water droplets will not fall directly from your hand, but will slide down your arm, making it difficult to fall to the ground."

"In this case, there will be a clear difference between the 'height' of water dripping from the hands and the 'height' of tears dripping from the cheeks."

Keep your hands in a natural downward position, about 1 meter above the ground.

For example, if Mr. Zhang Tian maintains a standing posture, the position of his cheek and chin is about 1.5 meters above the ground.

There is a long way between the two.

"Analogy the knowledge of bloodstain trace analysis to water droplets, you can know:"

"The dripping water droplets formed by the same amount of liquid, the height increases, and the larger the diameter of the water droplets, the more protrusions."

"There is a good linear relationship between the size of the droplets and the height of the droplets."

"In this way, we can roughly guess from what height the droplets fell from through imitation experiments."

Conan gave such a solution.

He said firmly and confidently:

"We can do experiments now to see if the 'droplets' are dripping from our hands or from our faces."

"If it's the latter, then those droplets are likely to be tears."

There was silence.

I only heard Gray Yuan say quietly.

"What if Mr. Zhang Tian had washed his face at that time?"

"It's easier to lick with your tongue..."

"And you can't go wrong."

Conan: "........"

................................

Soon after.

Based on a quick and accurate verification, Conan finally confirmed that those few drops of "water" were tears.

"Goo-goo.... Bah!! ”

Conan spat out the mouthwash fiercely and firmly gave the final conclusion:

"That's right... It's salty. ”

"And it's unlikely to be sweat – every room in the theater is air-conditioned, so it's not so hot that it drips to the ground."

"So we can confirm that Mr. Zhang Tian was crying at that time."

"Connect with the bizarre lies he made in the text message."

"It's not hard to imagine that he was charging his phone in the break room while crying alone."

Later, Mr. Zhang Tian's daughter called him out of the blue.

He answered the phone while letting it continue to charge, but he didn't dare to say anything.

Then he hung up the phone and secretly cried while pretending to be in a normal mood and texting his daughter to communicate.

In the process, Mr. Zhang Tian's tears fell to the ground.

"He probably wiped his tears with his hands, which also stained his palms with water – which greatly increased his risk of electrocution."

"So after texting and about to unplug the charging plug, he was electrocuted."

Conan paused slightly, and his tone became deep:

"After recovering from the electrocution, he went back to the screening room to watch the movie."

"I was a little strange, since he was unwell after the electrocution, why didn't he just sit in the lounge to rest, but went back to the screening room."

"Now that I've read those text messages, I know..."

"Perhaps, Mr. Zhang Tian, he really wanted to rush to see Gomera at that time, right?"

Mr. Zhang Tian mentioned in the text message that he would go back to talk to his daughter about the plot of "Gomera" in the evening.

During the conversation, he was still in front of his daughter and showed that he was interested in the Gomera series.

But actually...

"With his age, identity and experience, I'm afraid he won't like to watch this kind of special effects drama, right?"

"He rushed back to the screening room to watch the movie, probably because he only now learned that his daughter also likes to watch Gomera."

"Therefore, he wants to finish the movie and fulfill his promise of 'going back to talk about the plot with his daughter at night'."

Conan made a conclusion with emotion.

And in everyone's mind, such a picture can't help but emerge.

Mr. Zhang Tian broke free from the electrocution.

He staggered to his feet, leaned against the wall, and took a moment's heel.

Because of the damage to the cranial nerves caused by the electric current, as well as the lack of oxygen in the brain caused by heart dysfunction, his brain has begun to feel a little dizzy.

He poured cold water on his head to stimulate him to wake up, and then thought of the promise he had made to his daughter in the text message.

So, instead of sitting on the spot to rest, he leaned against the wall, bent over, and slowly moved back to the screening hall.

By this time, his consciousness was completely blurred.

In the end, he watched the movie his daughter liked to watch and died suddenly in a daze.

"Nice story."

"But..."

Gray Yuan was silent for a while, and asked:

"Is there still a possibility:"

"It was Mr. Zhang Tian who was planning to commit suicide, and before committing suicide, he cried with grief."

While he was crying, he suddenly received a call from his daughter.

"He didn't tell his daughter the truth, because he couldn't bear to let her realize that he was going to a dead end."

"Second, leaving such a text message conversation and making a promise of 'going back to accompany my daughter at night' can also make his electrocution look more like an accident than a suicide."

"This—" Conan was speechless for a moment:

Actually, he can think of it.

According to the speculation put forward by Gray Yuanai, it can be completely explained.

But...

"But I still don't want to believe it."

"As a father, would he really cheat on his daughter and make false promises?"

"He said he was going home, but he only sent back a corpse."

"To do this... It's cruel. ”

Conan sighed deeply, his expression a little depressed.

After all, he still couldn't find strong enough evidence.

His reasoning may have been futile in its entirety.

"No, Conan, you're doing a good job."

Lin Xinyi shook his head and said approvingly:

"What you restored was the last moment before Mr. Zhang Tian's accident."

"At least you know, he's crying, and he's made a promise to his daughter to come home."

As a forensic doctor, while completing the criminal investigation work, he will also unconsciously do some "useless reasoning".

He imagines the details of the deceased's experience, imagining the environment, sounds, gestures, movements of that moment.

Try to experience the other person's mood and feel the other person's pain.

Doing so, of course, will not help solve the case.

But if you don't do these useless things, don't feel the feelings of the dead... As you slowly see more death at work, you will gradually lose your sense of humanity and even your sense of responsibility as a police officer.

"Alas..."Lin Xinyi also sighed lightly:

"At the end of the day, if there is no evidence in this case, there is no truth."

"Was it a malicious suicide deception, or was it a tragic accidental electrocution?"

"Legally, there is no doubt about the guilt, and the standard answer is the latter."

"And from our hearts..."

"The truth can only be the one we want to believe."

Conan had chosen an answer he believed more.

"What about you?"

Gray Yuan Wai looked at Lin Xinyi with some curiosity:

"Do you also prefer to believe that Mr. Zhang Tian is a good father who died unexpectedly?"

"I..." Lin Xinyi substituted himself and thought about it seriously.

"Yes, I'd rather believe the latter."

Although it is not as good as Mao Lilan, Lin Xinyi's empathy ability is also very strong.

He unconsciously substituted himself into the desperate situation that Mr. Zhang Tian was in, and then muttered to himself:

"If it were me, even if I really wanted to commit suicide, I suddenly received a phone call from my daughter full of concern..."

"I'm afraid I'm going to become nostalgic for the world, right?"

Lin Xinyi was very emotional, as if he was really like Mr. Zhang Tian and had a lovely daughter.

As he spoke, he involuntarily stretched out his hand.

I want to touch the head of Gray Plains.

Gray Plains: "......"

"Damn, don't put me in the role of a daughter..."

She gritted her little tiger teeth and squeaked, as if she wanted to swallow Lin Xinyi's fingers in one gulp.

But Lin Xinyi still touched her soft tea hair:

"Listening to the voice of the person you love, how can you bear to leave this world?"
