"So it's suspicious?"

Listening to Conan's words, Shu Yunwen and Koizumi Hongzi glanced at each other, and then a solemn smile appeared on their faces: "...... That's not necessarily!~"

Shu Yunwen's words fell, and Koizumi Hongzi turned around and walked towards the fishing net where the corpse was hung. Seeing this, Tsukamoto Shumei, Loriai, and Kimishima Kana also hurriedly followed, and as for Koshisui Nanatsuki, she also followed after a slight hesitation.

Watching Shu Yunwen and them walk away, Conan, Xiaolan, and Hattori Pingji were all surprised, and then Hattori Pingji asked strangely: "What does Yunwen mean? What is 'not necessarily'? Could it be that he still wants to say that these fishtail traces are all left by real mermaids?"

"Okay, leave that guy alone! Brother Yunwen is always so mysterious......" Conan pursed his lips with a look of disdain, Xiaolan snorted twice, and then his white hand gently grabbed Conan's ear:

"You're right, Yunwen-san really doesn't need you to take care of it! It's you, Conan, you really don't change your teachings! When you get home, you just wait to copy the school rules!"

Conan listened to Xiaolan's words, looked confused after a "ahhh

"No, Sister Xiaolan, I really didn't have ...... just now"

MMP! We have enough handles in Xiaolan's hands now, if Xiaolan thinks that we are a pervert with a disgusting hobby, then won't we be miserable in the future?

Before Conan finished speaking, Hattori Heiji had already coughed lightly twice to interrupt Conan's words, and then stroked Conan's dog head and said with a smile: "Xiaolan, Conan's education problem should be talked about later! After going back, it doesn't matter how many times you ask him to copy the school rules, the most important thing now is the case!"

Hattori Heiji said, then turned his head to look at Uncle Maori and said, "Mr. Maori, I guess you have also thought of it, right? The case on the island is inseparable from the Dugong Arrow, and now Miss Shoumi, Miss Naoko, who has been killed one after another, and Miss Saori, whose whereabouts are unknown and may be hiding from someone, all believe that Changshou Po has eaten mermaid flesh and is immortal, and she has mana...... Now, Miss Naoko was killed, but the dugong arrow was taken by the murderer, and it is obvious that the murderer took the dugong arrow for a purpose, and the murderer must have a certain relationship with the dugong celebration......"

Hattori's words fell, and Conan also pinched his chin, squinted his eyes and muttered, "It's a pity! We don't know the number of the person who bought the dugong celebration number plate yesterday, maybe there will be some clues on it......"

Conan was muttering when Kimie Shimabukuro, who was next to him, suddenly spoke, "Do you mean numbered plates? If you want to know who bought what numbered tickets, it's very simple." I have all the names on the roster for every number, just look at it to know ...... Well, are you going to go and look at the roster now?"

"Really? That's great!"

Conan and Hattori Heiji's eyes lit up, and Shimabukuro Kimihui smiled slightly: "You're welcome, it's just a trivial matter...... However, now that the police are investigating, we may have to wait a while before we can leave. ”

"That's just as well. Conan and Hattori nodded.

Immediately after, Shimabukuro Junhui suddenly asked, "By the way, what does your friend named Shu Yunwen do......?" I seem to believe that there are mermaids......"

"Brother Yunwen?" Conan turned his head to glance at Shu Yunwen, then pursed his lips and complained, "We seem to have said yesterday, he is a soul eliminator! That guy is obviously a very powerful detective, but he doesn't admit it, and he still claims to be a soul slayer...... If you want me to say, he's just a swagger!"

"-Miss Shoumei, who was killed yesterday, seems to have been deceived by him very badly......"

"Removing the Spirit...... Shimabukuro, Kimie nodded, clenching her fists vigorously......

......

In front of the quarantine fishing net of Ebihara's house.

The rain was falling in the sky, and the uncles of Fukui Prefecture were surrounding the corpses, surveying the scene, while Shu Yunwen, Tsukamoto Shumi, and Koizumi Hongko drilled through the fishing nets beside them, observed the fishtail marks left on the sand, walked to the wave line, and looked up at the endless sea:

"Yunwen-san, do you feel the residual energy?"

"Nope. Shu Yunwen shook his head, then bent down and squatted on the ground, looked at the marks on the ground, and asked, "What about you?"

"Neither did I. Koizumi Hongzi also shook her head, and then squatted on the ground, gently grabbed a piece of fish scales on the beach, and suddenly recited a spell in her mouth.

Next to Shu Yunwen and them, Sumi Tsukamoto and Nanatsuki Koshisui listened to the conversation between the two, and they were all a little strange, and then Nanatsuki hurriedly asked, "Yunwen-san, what are you talking about? Also, the murderer of Miss Naoko, could it really be ......?"

Before Koshisui Nanatsuki finished speaking, Koizumi Hongzi suddenly spoke: "...... That's right, the murderer is indeed a mermaid!"

When everyone heard Koizumi Hongzi's words, they looked over together, only to see that the fish scales in Koizumi Hongzi's hand were wrapped in a small pinch of blue flames, and with the flames burning, the fish scales finally turned into a ball of foam, and then disappeared.

Shumi Tsukamoto looked at this scene, couldn't help but let out an "ah", and said in surprise: "This, this is ......"

"This is the characteristic of all body tissues in the mermaid. The mermaid's body, when eroded by the energy of the dark world, will slowly turn into foam until it disappears, just like the mermaid in the fairy tale who was enchanted by a witch. Shu Yunwen opened his mouth to explain, and then looked down at the fish scales on the ground, his eyes were a little incredulous, "These fish scales should have fallen from the mermaid's body, so they also have the same characteristics......

“...... However, I didn't expect that there would be mermaids here!"

How does this have anything to do with fairy tales?

Tsukamoto Shumei and the others were a little confused, and Loriai reached out curiously and grabbed a few fish scales, frowned and asked, "...... How did so many fish fall off here? Could it be that mermaids lose their scales when they come ashore?"

Lori's words fell, and Koizumi Hongzi immediately replied: "As far as I know, it is difficult for mermaids to walk after they come ashore, and when they move greatly, it is normal to lose a few unstable scales just like ordinary people lose a few hairs." But...... I've never heard of fish scales falling like this......"

"Is that merfolk sick?"

"Do mermaids lose their scales when they're sick?" Nanatsuki asked—

In other words, fish lose their scales when they are sick, she knows it, is it the same for mermaids?

"Yes!" Shu Yunwen nodded in response and continued to explain, "The mermaid is an alien creature that has the common characteristics of humans and fish, and if it has a fish-like 'skin disease', or if the tail part of the fish is injured or inflamed, even if the wound is not big, it will fall off the scales of the fish......

“...... I don't know what kind of problem this mermaid 'murderer' belongs to......"
