Mouri Kogoro's "young" mind suffered a critical blow of 10,000 points. He was holding the piano with some injuries, but unexpectedly found a tape recorder inside the piano.

He quickly picked up the recorder and said seriously: "Everyone, please look! The sound was not made by the 'cursed piano', but by this recorder."

With that said, Kogoro Mouri stopped the recorder and turned off the BGM "Moonlight".

At this time, Mouri Kogoro's eyes caught Asai Narumi in the crowd.

"Dr. Narumi, please take Mr. Kawashima down to have a rest first."

"Oh well."

Asai Narumi walked towards Kawashima Hideo, passing by Conan who was thinking.

Conan, who had extremely sensitive senses of smell and hearing, immediately heard an unusual subtle sound.

Paji, paji...

This sound is a bit like treading water.

Conan followed the sound and immediately looked at Asai Narumi's feet.

The black silk on the heel is a little crystal clear under the reflection of light, as if...

Take it with a grain of salt!

Of course, Conan would not think that Dr. Sung-shi's feet were salty and that's why the salt particles appeared on them.

The salt particles are left behind after the seawater evaporates, and the sound of treading water should be due to the fact that the seawater on the toes is covered by slippers and has not completely evaporated.

She just went to the beach!

"Dr. Chengshi, there are grains of salt on your socks. You have just been to the beach, right?"

Conan's words immediately alerted Mouri Kogoro next to him.

Even if Kogoro Mori didn't survey the scene carefully, he could still see traces of water dragging on the ground.

And the water marks dragged all the way to the back door of the piano room, which led to the seaside.

Therefore, the movement trajectory of the prisoner taking the unconscious Hideo Kawashima should be toilet → piano room → seaside → piano room.

Thus...

"Dr. Chengshi, what did you do at the beach just now?"

Mouri Kogoro looked at Asai Narumi with great momentum, as if everything had been revealed.

But at this moment, an unexpected person stood up.

"I'm sorry, Miss Cheng Shi was walking on the beach with me just now, so her shoes got wet."

The person who spoke was none other than Qin Zhibo.

As for Qin Zhibo's testimony, both Mouri Kogoro and Conan were a little surprised, but they could not doubt it.

Because no matter how hard they racked their brains, they would never have thought that a detective who came to Moon Shadow Island from Tokyo because of today's temporary plan would give false testimony to the female doctor they met for the first time.

And what's more important is Xiaolan's next speech.

I saw Xiaolan looking at Qin Zhibo and Asai Narumi with a gossipy face, and said in surprise: "Mr. Qin should have invited Miss Narumi after seeing her in the public hall, right?"

In fact, when Qin Zhibo was about to leave the team, Mao Lilan saw Qin staring at Asai Narumi.

Coupled with Qin Zhibo's chatting behavior in the morning, Mao Lilan, who also has some love brain, naturally thought of this causal relationship.

In this way, Mao Lilan created a reasonable motive for Qin Zhibo and Asai Chengmi's "beach date".

Strike up a conversation in the morning, invite for a walk in the evening...

There is nothing wrong with Qin Zhibo and Asai Narishi!

So Mouri Kogoro regarded the two as witnesses, "Ahem, did you two see any suspicious people when you were walking on the beach?"

"No."

"No."

Both men shook their heads, putting the investigation into the attack case of Hideo Kawashima into a bottleneck.

So next, Mouri Kogoro announced the existence of the murder notice letter to everyone. Although no one died in this attack, it must still attract enough attention.

If any of the villagers find any suspicious person, they should report it to him, Kogoro Mori immediately.

In addition, it was just an assault case. If not even the wallet was lost, the case was not big enough to alarm Mr. Megure who was far away in Tokyo.

In addition, the murder notice letter was a riddle and did not indicate the exact time, place, or person.

Therefore, the only police officer on the island was an old uncle who was over sixty years old.

...

As soon as the old policeman arrived at the piano room, he recognized Mouri Kogoro based on his name.

"Ah! Is it the famous space pilot?"

Mouri Kogoro was ashamed again and could only directly introduce the circumstances of the attack to the old policeman.

Conan next to him rolled his eyes at the unreliable old policeman and didn't take the policeman's role seriously at all.

The biggest role of this elderly man is to record that such a case happened on Yueying Island.

The thing that confuses Conan the most now is why the prisoner stopped committing crimes.

He took Hideo Kawashima to the beach in a daze, and combined with the contents of the murder notice letter, he probably wanted to drown him.

According to criminal psychology, criminals who warn of murder in advance are planned crimes.

It is basically impossible for this kind of criminal to regret the murder and then stop.

Therefore, what caused the crime to be suspended must be some unexpected situation that caused the murder plan to be interrupted.

For example, someone suddenly appeared nearby?

Thinking of this, Conan looked up at Qin Zhibo and Asai Narumi again, and asked with childlike innocence and high emotional intelligence: "Brother Qin, sister Narumi, did you really not encounter any suspicious people when you were walking on the beach?"

"No..."

Asai Narumi's single ponytail swayed, causing Conan to fall into new thoughts again.

Could there be other witnesses?

Qin Zhibo looked at Conan who was thinking, knowing that Conan would not easily give up looking for the prisoner who attacked Hideo Kawashima.

However, under the guidance of Qin Zhibo, Aso has tried his best to erase any evidence that may be left at the scene.

He and Aso's footprints could be wiped away with Kawashima Hideo's body like mopping the floor, and then they could go out through the woods next to the public hall.

As for why Aso was not asked to deal with the salt particles on his socks, he also wanted Conan to discover this in time and raise questions.

Through his own testimony, he can naturally rule out the suspicion of Aso.

In this way, even if Mouri Kogoro is very serious and invites Megure to come to the scene in person, he will not interrogate someone who already has a sufficient alibi.

Then we won't find out that Aso is actually a transvestite.

But the only thing Qin Zhibo is worried about now is that someone on the island knows that Keiji Aso had a son who had been receiving treatment in Tokyo due to frailty.

Once his son's clues are exposed, Conan can at least get a general direction of reasoning.

...

After explaining everything to the old policeman, it was already getting late and it was time to rest.

Since what happened this time was not a murder, and there was no absolute connection between the case and the piano, the Maori family decided to rest at a hotel on Moon Shadow Island.

When they reached the fork in the village, Qin Zhibo waved to the Maori family.

"Then let's say goodbye here and see you tomorrow."

Looking at Qin Zhibo who was lagging behind, Mao Lilan asked puzzledly: "Mr. Qin, why don't you go to the hotel to rest?"

"I'm going to stay at Miss Chengmi's house tonight." Qin Zhibo glanced at Aso Minoru, who had a reddish face next to him.

"Her family is quite big..."

After Qin Zhibo finished speaking, the Maori family all showed their classic beady eyes.

Mouri Kogoro: I am also an uncle, why have I never encountered such good things when traveling before?

Mao Lilan: Mr. Qin is really surprisingly capable of "doing"...

CONAN: Is this the adult world?

Qin Zhibo and Asai Narimi walked on another village road, their backs gradually drifting away, leaving the Maori family with endless reverie.

But despite his reverie, Conan still doubted Qin Zhibo's testimony just now.

If Qin Zhibo and Asai Narimi establish a relationship as boyfriend and girlfriend, will the testimony just now be invalidated?

As we all know, the testimony of two people who are closely related is not legally binding.

But in just one day, it is difficult to tell whether a relationship between a boyfriend and a girlfriend is established. It is possible to have a one-night stand or simply fall in love at first sight.

Also, with Qin Zhibo's ability, if he wanted to help Asai Narumi, he would definitely remind Asai that there were salt particles on her socks and ask her to get rid of the salt particles.
