At half past nine in the evening, on the sea near the island of America.

The sound of water in the sea is bursting, and the bright moonlight shines on the blue water, and as the sea ripples, it glows with a silver scale.

Suddenly, there was a sound of "brushing" in the seawater, and then I saw a girl in a purple skirt riding a broomstick, flying out of the sea, flying in the air, staring at the sea below, frowning:

"The merfolk's grave isn't here either...... It's strange, I've searched the area within a two-nautical-mile radius of the American Island, but why haven't I found it yet? Could it be that the mermaid legend here is fake? However, the mermaid statue in the shrine should have been blessed by a real mermaid mage...... There should really be a mermaid here......"

Koizumi Hongzi thought in his heart, and flew twice in the air on a broomstick:

"Perhaps...... Isn't it because of my red magic ability that I can't sense it?Speaking of which, if you want to talk about a place like searching for graves, Yun-Wen-san might be better at it than me, right? Why don't you ask Yun-wen to help you?"

Koizumi Hongzi pondered, reached out and pulled out a mobile phone from inside her skirt, and frowned after glancing at it:

"Damn! There's no signal here! Looks like you'll have to go back to the island if you want to call......"

Thinking about this, Koizumi Hongzi stuffed her phone back into her skirt and flew towards the American island on a broomstick......

……

Rice flower town, inside the café.

Seeing Conan and Hattori Heiji leaning against the wall and walking into the bathroom together, Shu Yunwen put down the small plate in his hand speechlessly, and complained:

"I said, why did these two guys go in with the wall again? Did they really have a bad stomach? How do I feel that they met and got drugged......

Shu Yunwen's words fell, Loriai, who was eating cake, choked on the cake, "cough cough", Tsukamoto Shumei immediately took toilet paper to wipe the cream on Ashbara's mouth, and said with a smile: "Xiao Ai, you eat slowly, don't be in a hurry......"

"Well, thank you. Lori thanked Shumei, and at the same time, Shu Yunwen's mobile phone suddenly rang.

Shu Yunwen hurriedly took out his mobile phone from his pocket of his clothes, and was slightly stunned when he looked at the number-

Strange, isn't this the number of Koizumi Hongko?

In the middle of the night, what is she calling for?

Shu Yunwen was confused, glanced at his girlfriend sitting next to him, pressed the answer button and said, "Hey, hello, is it Koizumi?"

Next to Shu Yunwen, Shumi Tsukamoto stiffened when she heard the title "Koizumi-san", her eyes secretly aimed at Shu Yunwen, and she continued to wipe her mouth absentmindedly for Lori-

At this point in time, some people are planning to wash and sleep, right? Koizumi Hongzi, what is the matter with her phone call?

In other words, although Shu Yunwen has repeatedly stated that Koizumi Hongzi likes Black Feather Kuaito, Shumei is still a little worried that this witch will pry her corner and rob her boyfriend......

"That's right, it's me, hello Yunwen. Koizumi Hongzi's voice came from the phone, "Is there anything you have to do now?"

"Well, it's nothing, I'm having dinner with Shumi-chan!~"

Shu Yunwen spoke, his eyes looked at Tsukamoto Shumei who was peeking next to him, and took a look at Loriai, the corners of his mouth couldn't help twitching, he reached out and patted Shumei's arm, and stretched out his finger to point at Loriai.

Shumi Tsukamoto turned her head to take a look, only to realize that because she didn't look at Ash Yuan when she wiped her face just now, she actually smeared the cream on the paper on her face-

That look, at first glance, looks like applying a thick layer of inferior foundation!~

Tsukamoto Shumi was stunned for a moment, before she screamed "ah", and quickly pulled out a stack of toilet paper from the paper drawer next to her, and continued to wipe her face with an apologetic face:

"I'm sorry, Xiao Ai, I accidentally ...... just now"

MMP!

You accidentally can smear the cream on my face, ah, the soul is light~!~

You just didn't look at my foolishness!

Lori complained in her heart, took the tissue from Tsukamoto Shumi's hand, wiped it on her face a few times, and then got up and said, "I'll wash my face." ”

Lori got up to leave, and on the phone, Koizumi Hongzi asked again, "Is it time to have dinner now?"

"Well, something tricky today. Shu Yunwen didn't explain too much, and cut straight to the point, "Xiaoquan, do you have anything to do with me?"

On the other side of the phone, Koizumi Hongzi stood on the edge of a cliff and listened to the tsunami voice: "That's right, Yunwen-san, I have something I want to ask you for help...... You know the Mermaid Grave, right?"

"Mermaid Grave, of course I know!~" Shu Yunwen nodded-

The mermaid race, after being "created" by the people of the dark world, still retains many human habits, such as being buried in a grave after death, which is one of them.

However, because most of the mermaid's graves are in the sea, they are rarely found!~

Shu Yunwen was thinking about it, and Koizumi Hongzi spoke again: "It's easy to say if you know." Recently, when I was making a potion, I needed a long-lived grass......"

"Immortal grass?" Shu Yunwen was stunned for a moment when he heard this name, and after thinking for a while, he asked rhetorically, "You are talking about mermaid grass, right?"

In other words, Shu Yunwen remembered that it was mentioned in the family inheritance that mermaid grass is a strange medicine that grows next to the mermaid cemetery, and only one plant will appear next to a mermaid skeleton, and its whole body is composed of dark energy, and the shape is a water-blue mermaid, which is an auxiliary drug for refining longevity pills, so some people also call it longevity grass-

According to Shu Yunwen's speculation, the folklore says that you can live forever by eating mermaid meat, and nine times out of ten there are people in the dark world who told ordinary people about the fact that mermaid grass can refine longevity pills, coupled with the strange appearance of mermaid grass, and finally spread it like this......

"Well, yes, it does have that name. Koizumi immediately replied, "In order to find the longevity grass, I checked the handwriting at home, and found that the American island near Tokyo, Japan, has been active by mermaids for 200 years, and then I rushed here today to find the grave of the mermaid, but I have never found ......."

Shu Yunwen was stunned when he heard this: "Then you are calling me to ...... Looking for my help?"

"That's right!" Koizumi Hongzi responded, "Yunwen-san, you specialize in ghost and object spells, I think you should be better at finding cemeteries than me, so ......"

"That's the case!" Shu Yunwen nodded suddenly and agreed directly, "I'm really good at finding graves, but I'm not completely sure...... Well, you can tell me a time, I'll rush over and help you as soon as possible!"

"Okay, thank you so much!~" Koizumi Hongzi immediately said, "I'm on the island of the United States now, but it's getting late, you can just take the tourist boat here tomorrow." I remember that the passenger ships that came here sailed twice a day, and they went out to sea at about eight o'clock in the morning—"

"-yes, that's right. The scenery here on the American island is good, the seafood is delicious, you can bring your girlfriend with you by the way, it is a trip!~"

"Well, okay, no problem!~"

Shu Yunwen agreed, and after chatting with Koizumi Hongzi for a few more words, he hung up the phone.

As soon as the phone was hung up, Shu Yunwen immediately turned his head to look at Shumi-chan, who was eavesdropping with his ears pricked up, and explained with a smile: "It's Koizumi-chan's phone, she has asked me for help with something, asking me to go to the American island near Tokyo tomorrow." By the way, Koizumi-san, I also invited you to go with me, so it's a trip......"

"Oh, really?" Tsukamoto replied, pouting slightly, "She knew I was next to you, so she invited me, ......right?"

Yo he, our family is cute and cute, is this jealous?

Shu Yunwen looked at Shumei in his pouting mouth, couldn't help but reach out and pinch Tsukamoto Shumei's nose, turned back and forth, and said with a smile: "...... Shumei, you're so cute, even if you're not next to me now, I'll go with you!~"

"Hmm......" Tsukamoto Shumi was stunned for a moment, turned her head to look at Kana Kimishima, who was sitting opposite and eating dog food silently, and beat Shu Yunwen's chest with a small fist embarrassedly, and said coquettishly:

"I hate it, Yun Wenjun, don't pinch someone's nose......"

Tsukamoto's beautiful words fell, and Shu Yunwen leaned on the back of the seat "Duang", and the corners of his mouth twitched-

Why are you beating me in the chest again?

Other people's girlfriends are coquettish and ask for money, and you are coquettish with Shumei sauce......

Shu Yunwen stretched out his hand and touched his stuffy chest, and continued to discuss with Shumi Tsukamoto, and decided to go to American Island together tomorrow.

The two of them discussed, and Tsukamoto Shumi raised her hand to look at her watch, and then said "ah": "We have to get up early tomorrow to take a passenger ship...... It's 9:45 now, and we have to go back right now, pack our bags, and get some rest......"

"Well, that's right. Shu Yunwen also raised his hand and looked at his watch, and then said, "...... Then we'll wait for Gray Yuan to come back from the bathroom and leave!~"

Shu Yunwen's words fell, Tsukamoto Shumei nodded first, and then asked with some worry: "By the way, what should Conan and Hattori do? They have been having diarrhea, there will be no problem, right? Shall we wait for them to come out and take care of them?"

"No need!" Shu Yunwen shook his head, "They are not children, they will take care of themselves." ”

When Tsukamoto Shumei heard this, she said, "Ha": "...... But, Conan, he's a child!~"

"Uh......" Shu Yunwen concluded, and then defended, "I mean, Hattori is also a high school student, it's no problem to take care of the two of them, don't worry!"

Shu Yunwen chatted with Sumi Tsukamoto and Kana Kimishima for a while, and after Loriai came out of the bathroom, he got up directly and walked out of the store and took a taxi to leave.

Shu Yunwen and they didn't have long left, Conan and Hattori Heiji walked out of the bathroom together with the wall, and their eyes fell on the position where Shu Yunwen and they were sitting, and they were all stunned:

"Where's Shu Yunwen, gone?"

"Damn, this bastard, he's going to run fast, or I'll rush over and shit him right now!"

"Yes! him!"

"Look at it! The next time I meet him, I'll definitely give him a good look!"

“……”

Conan and Hattori Heiji were indignant and expressed their determination together, and suddenly their stomachs were "gurgling" again.

When the two detectives heard the voice, the corners of their mouths twitched twice, and after glancing at each other, they turned around again and walked into the bathroom with their hands on the wall......

……

Half past ten in the evening, Kakudo Town.

In one of the F.B.I. bases, Shuichi Akai wore headphones, listened to recordings, and stared at two sketches on the table in a daze.

Suddenly, Akai Shuichi felt that it was dark next to him, and then the headphones on one side were taken off, and then a female voice sounded: "Shuichi, what are you listening to?"

Akai Shuichi hurriedly pressed the stop button of the Walkman, then turned his head to look at the side, slightly stunned: "Judy? It's you, aren't you in the house in Rice Flower Town?"

"You haven't been seen for a few days, so I heard from my colleague that you were here, so I rushed over immediately. Judy replied with a smile, then looked at the two sketches on the table, a little distracted, "Is this Miss Akemi......'s sketch?

Judy looked at Chengshi's portrait, her brows suddenly furrowed, and she reached out and pinched her chin: "...... It's strange, this person feels so familiar to me, it seems that I have seen it somewhere!"

Akai Shui's eyes lit up when he heard this, and he asked urgently, "Judy, have you seen this woman?"

"Well, okay. Judy pinched her chin and pondered, and after about half a minute, Judy suddenly punched her fist and said, "I remember! I saw this person in the files of the Japanese police! Shuichi, do you remember Belmode sneaking into the Metropolitan Police Department and stealing the case files?"

"Of course I do!" Akai nodded, and Judy continued:

"The reason why Belmode stole all of the Māori detective's case files remains a mystery to this day. In order to investigate the matter, I asked my superiors to communicate with the Japanese police, and internally copied all the cases in which the Maori detectives were involved, and checked them one by one, and this person was very similar to the murderer in the case that happened on Moonshadow Island! I remember his name was ......"

“…… Narumi Asai?"

Akai Shuichi's expression suddenly became serious, and then he asked, "How is that murderer now......?" It's dead, isn't it?"

"Huh, how do you know?" Judy looked a little surprised, "The police file mentions that the murderer burned himself to death before he was caught, and he was playing moonlight on the piano when he died...... What? Are you interested in this person?"

"Yes, there is some interest. Akai Shu nodded, "You just said that you copied the case file of the Metropolitan Police Department, right! Can you please bring that Asai Narumi file and show it to me?"

"Okay, of course!"

Judy answered, turned to get the file, Akai Shuichi squinted, pinched his chin and thought-

In his opinion, Akemi and that Asai Narumi can "walk" together, there must be something in common!

All of this is very likely to be hidden in the dossier!
