"Rii saved my life once!"
Not long ago, when Tsubasa Masuda introduced Rii Hino to Mōri Kogoro, he was so proud and boastful.
At that time, Rii Hino was a little shy, so she quickly changed the topic.
A month ago, Tsubasa Masuda went to a mountain alone because of work.
There was a strange scientist living in that mountain.
He investigated for a long time before finding out the news.
Their newspaper had wanted to interview this person for a long time.
The mountain was more difficult than he thought.
Tsubasa Masuda was a person who usually focused on writing articles. Occasionally, he would gather with his friends. He belonged to the big city.
This place was very difficult for him.
When he was walking across a pontoon bridge, he accidentally fell from the top.
The river was very wide and deep, and the water was very fast.
He drank a few mouthfuls of water.
He struggled desperately.
However, he was not very good at swimming.
Soon, he couldn't hold on anymore.
Just when he was feeling afraid, a woman suddenly jumped down from above.
The beautiful woman was very good at swimming.
Even when he was unconscious and was still dragging her down, she still managed to bring him safely to the shore.
Tsubasa Masuda didn't know what happened after that.
He only knew that he was in the hospital when he woke up.
He just drank some water and it was nothing serious.
After he woke up, the hospital agreed to let him be discharged.
The woman didn't appear from the beginning to the end.
This made Tsubasa Masuda a little depressed.
She saved his life.
No matter what, he had to thank her in person.
When Tsubasa Masuda was hospitalized, the woman left her contact information with the hospital.
In the end, Tsubasa Masuda finally got in touch with his savior.
When the woman received his call, she was obviously stunned.
Then, she asked about his situation.
Just like that, they met.
The beautiful woman was called Rii Hino.
She was a member of a detective club.
The reason for her appearance here was very simple.
In their opinion, this kind of place where even the police didn't come often, it was easy for a murder to happen.
They had been to many places like this.
Some places were even more difficult than here.
Occasionally, they would borrow a place to stay.
However, after so much effort, they still didn't even encounter a simple case.
Tsubasa Masuda was an editor.
In their newspaper office, he had also edited the manuscripts of some novelists.
In this way, it was easy for them to get along with each other.
Gradually, they had a good impression of each other.
After a few days, they had the idea of getting married.
Rii Hino's and Tsubasa Masuda's friends were very surprised.
The good friend of a certain detective, he had a nostalgic look.
Until now, he could still recall the amused expressions on those people's faces when they told him the news.
She was was gone.
His wife, who was about to get married, was killed just like that.
Tsubasa Masuda couldn't accept this fact.
He looked, he was very.
And just like him, Rii Hino's three best friends were also very sad.
They had lost two friends in three months.
Two?
A certain primary school detective asked in a very young and naive voice.
The person who just asked this question, Ayaka Yanagita, looked at Conan Edogawa and said it naturally.
There were originally five people in their detective club.
Three women and two men.
Ayaka Yanagita carefully introduced Conan to them.
The other girl was only seventeen years old.
Her name was Wei Uesaka.
She was the smartest person in their club.
She was also very physically strong.
Even the two men had to be taken care of by her.
Wei Uesaka's death was an accident.
They fell into a large river.
The river was faster than any other time they had encountered it.
Even they didn't manage to return to the shore.
Only Wei Uesaka.
One by one, she safely landed the four of them on the shore.
She still remembered that the place where Rii fell was the furthest from the shore.
When Wei Uesaka saved her, she had almost no strength left.
In the end, she couldn't save Rii.
She also sank to the bottom of the river.
Then, she never floated up again.
Rii Hino couldn't hold on anymore.
Just as she was sinking, one of the people who lived nearby finally heard their loud cries.
That person saved Rii Hino.
When Wei Uesaka came up, she was already a corpse.
Their lives were saved by Xiao Wei.
Using her own life.
Saying this, Ayaka Yanagita revealed a bitter smile.
So when they saw Tsukasuke Masuda fall into the water, they were all stunned.
The water reminded them of what had happened back then.
They couldn't move at all.
Rika Hino was the worst swimmer of them all.
It was simply inconceivable for her to save a person from such a river.
So when she jumped into the water, they were even more stunned.
She was simply too reckless.
They thought.
She had actually managed to rescue him.
When she put the drowning person on the ground, she showed them a big and bright smile.
Murase Masaki helped with some simple first aid measures.
They were already very familiar with these things.
Something flashed in the eyes of a certain primary school detective.
He thanked Yanagida Kaori and then left.
Only Ayaka Yanagita was left with a puzzled expression.
That person's motive for murder.
He thought he already knew.
Conan Edogawa's face was full of confidence and certainty.
Officer Mugo sent people to search all the nearby trash cans.
The residue that was smeared with poison must have been thrown around here.
At this moment, those people had already returned.
But the answer they brought back was disappointing.
They searched everywhere but couldn't find it.
In this way, those things should still be on the murderer's body?
Officer Mugo revealed his half-moon eyes and looked at the suspects.
At this time, a certain primary school detective suddenly made a sound.
He attracted everyone's attention.
That handkerchief was so strange!
A certain primary school detective pointed at the handkerchief and said with a very innocent look.
Dapingkuang casually stuffed it into his pocket, when he took it out again, it was also messy.
But the dried water stains on the top …
What happened to the water?
A certain muddle-headed detective naturally wanted to smash the head of a troublemaker.
However, he was careless and allowed Conan to dodge it.
Mōri Kogoro missed.
From the looks of it, he didn't seem to care about this matter at all.
Officer Mugo carefully looked at the handkerchief, he didn't think there was a problem with it.
At this time, a certain primary school detective found another handkerchief of similar size and material.
He did what they had just said.
Every step had to be done in order.
The handkerchief was drying at an accelerated rate.
A certain primary school detective handed the handkerchief to Officer Mugo.
His face showed an expression of "That's it."
You should have guessed it, right?
Officer Mu Mu carefully compared the two handkerchiefs with each other.
The problem with the water stains.
Officer Mugo remembered the problem that Conan -kun had mentioned before.
After he carefully compared them, he found that these water stains were indeed very different.
The one that Mr. Dapingkuang gave them was neat.
And Conan's was a little messy.
It didn't seem to have any pattern at all.
Because it was folded and placed after it was wet.
This way, the water stains on it would be trapped in a small space.
Just like that, a certain primary school detective revealed a somewhat sharp smile.
Is that so?
Mr. Dapingkuang.
He exposed this fact at once.
Dapingkuang didn't say anything.
A certain primary school detective didn't seem to be in a hurry at all.
He said that he thought that the handkerchief with the real poison should be in his pocket.
Was it convenient for them to take a look now?
The police immediately walked to his side.
No need.
Dapingkuang revealed a bitter smile.
He took out the same handkerchief from the other pocket of his clothes.
He looked at the primary school student. He said that he had already known that doing this would reveal something.
But he couldn't let his clothes get wet in advance.
"Why did you do this?" The first person to say this was Murase Masaki.
Riki Hino was their friend.
She had been their best friend for so many years.
Why did he kill her?
This was something that he couldn't understand no matter what.
"It's because of Miss Uesaka who passed away three months ago, right?" Dapingkuang didn't say anything!
A certain primary school detective said the answer for him.
His tone was very certain.
This made Dapingkuang a little surprised.
"How do you know?" He blurted out.
"In less than three months, she went from being a poor swimmer to being able to save a struggling man from a rushing river." Conan Edogawa spoke slowly and maturely.
In the end, he deliberately acted like a child again.
