After the person who came in spoke, everyone realized that the old hag-like figure who appeared was the longevity woman they were looking for.

It has to be said that when Guangyou saw this face, he immediately thought that the makeup was truly amazing. The old woman without makeup really looked like an old witch, with a face full of wrinkles and her features all seemed to be squeezed together. Her short stature was indeed startling.

Conan hesitated for a moment, then asked, "Grandma, I'd like to ask how you decided on the numbers for the Dugong Arrow draw?"

Grandma Changshou seemed not to hear Conan's question, standing there calmly with her cane supporting her. Conan initially thought it was because she was old and her hearing wasn't very good, but just as he was feeling discouraged, Grandma Changshou answered, "It depends. Sometimes I also use the numbers I draw when choosing horses."

She then laughed at herself, revealing that she had only a few teeth left. Guangyou couldn't help but adjust his glasses, which were about to fall off but didn't actually exist: "You're a kindred spirit with Uncle Mori. It's rare to see someone this old still betting on horses."

Heiji also asked the question that had been on his mind: "I'd like to ask why you don't sell more Dugong Arrows?"

The old woman answered quickly this time, tugging at her hair and saying, "That's impossible. I have very little hair left to use to bind those arrows."

"Great-grandmother, I've prepared your bathwater."

Junhui's voice came from afar, and Granny Changshou turned around and said to everyone in the room, "Excuse me, if you don't have anything important to say, I'm going to take a bath and go to bed."

Conan was about to ask his next question when the old woman ignored him and said to Kazuha inside, "By the way, that little girl with her hair tied up, the Dugong Arrow was originally a precious arrow that could exorcise demons and ward off evil. Once you let go of it, demons will build their nests on you. If it's a man, he will be buried and become a heartless ghost."

"If it were a woman, she would enter the water and become a mermaid who cannot speak, so I advise you to keep it with you at all times."

After saying that, he turned and left without looking back, leaning on his cane.

Leaving behind those nonsensical words, Kazuha was also somewhat worried, guessing that among the people present, she was the one who believed the most in these superstitious things.

After Heiji offered a few words of comfort, Kazuha felt much better. After a few hours of rest, the group set off for Kotobuki's memorial service.

Fortunately, Heiji and Kazuha brought their school uniforms with them this time. Although the occasion seemed a bit inappropriate, they were still more suitable than the clothes the group was wearing.

After changing into dark clothes, the group went to Sumi's house. Although they were not familiar with the deceased, they could take this opportunity to learn about the island.

When everyone arrived at the mourning hall, Junhui was already there. Uncle Mori looked at Benzo kneeling there and asked quietly, "That Mr. Monkyo didn't go back last night, right?"

Junhui nodded in agreement, "I heard he spent the whole night drinking with tourists at a tavern."

"Speaking of which, where is Miss Naoko? I clearly saw her name on the roster." Uncle Mori looked around but couldn't find Naoko.

Ran and Kazuha were about to go out to look for Naoko when a sudden clap of thunder rang out, illuminating the night sky. It came fiercely and went away quickly.

In that instant, Xiaolan seemed to see something terrifying and froze on the spot. Seeing Xiaolan's stunned expression, He Ye thought she was afraid of thunder and joked, "Xiaolan, you're not afraid of thunder, are you?"

Ran didn't react to Kazuha's joke. She raised her hand and pointed in the direction of the door: "There seems to be someone over there."

Another clap of thunder sounded, and this time Kazuha also saw a figure outside the door. However, it was only for a moment, and neither Kazuha nor Ran could see the figure's face clearly.

Heiji, drawn out by the commotion, asked, "What's wrong?"

"It looks like there's someone there."

Guangyou, who also poked his head out, narrowed his eyes slightly. The figure was slumped on the ground, his hands seemingly caught in a net. He then shook his head: "Tsk, another 'dead mermaid'."

Two more thunderclaps followed in quick succession. This time, everyone could see the figure's face clearly. Naoko, who had disappeared, had somehow appeared online, her head bowed, her mouth wide open. The two girls also screamed in perfect unison.

Another person has died, so the vigil can no longer continue. All the guests are watching from the corridor, and only Uncle Mori, who can be considered a professional, quickly borrows a camera to take pictures of the scene.

Heiji and Conan were also observing the deceased's condition and searching for clues at the scene. A row of footprints caught their attention, and when they picked up the shiny object next to the footprints, they found it was fish scales.

Just as the group was brainstorming, the police in charge of the island finally arrived at the scene. Fukui was a small place, and Uncle Mori wasn't that famous yet.

The lead officer noticed several people nearby and shouted, "Who are you? What are you doing?"

"We are investigating this case."

"This is none of your business. This is the work of the Fukui Prefectural Police," the lead officer said, slightly agitated.

Seeing the reaction, Guangyou felt that the police officer was going to be in trouble. He was excited, but at the same time, he found it a little funny that Uncle Mori's usually invincible face recognition skills had failed him.

Back in the corridor, after Ran and Kazuha heard that the footprints disappeared at the beach and that there were fish scales next to them, Kazuha, who had been brainwashed by mermaids all day, covered her mouth and exclaimed, "Could the culprit this time be a mermaid?!"

“How could that be?” Heiji couldn’t help but laugh. “How could a mermaid wear thigh-high boots? She probably doesn’t even know how to wear shoes.”

Heiji explained, "The murderer may have simply walked along the coastline, come to this fishing net, and then walked back along the coastline."

After inquiring about the situation, it was discovered that everyone said they had never seen Naoko. Although the culprit could not be identified, it was known that Naoko's dugong arrow had been taken.

Junhui stroked her chin, saying with some worry, "It seems that Saori also disappeared after the Dugong Arrow went missing. Could she also...?"

At this moment, an older woman nearby interjected, "Are you talking about Saori? I saw her near Mermaid Falls yesterday morning."

After this woman, an older man also said that he had seen Saori in the forest near the waterfall from afar.

To Kōyū’s surprise, Benzō’s attitude was that he was still drinking while his daughter’s life was in danger. It was hard to tell whether he was indifferent or simply didn’t care about his daughter.

When faced with Uncle Mori's question, Benzou calmly replied, "I just hope she doesn't turn into a mermaid like that girl who died."

Kōyū scratched his head, puzzled. "What's with the mermaid? What does it have to do with Naoko?"
