The people in the hall dispersed one after another. When Toru Amuro, who was the last to leave, reached the second floor, a dull sound was heard in the hall, and then all the bright lights went out. The first floor fell into darkness, and no one saw that the tables corresponding to the seats where they had just sat were lit up with a faint blue glow one by one, with the name of each of their corresponding goddesses written on them.

Among the smooth and beautiful cursive characters, the name Hecate is the only one missing.

The twelve names glowed dimly for a while. Perhaps the fluorescent powder or liquid gradually lost its effectiveness, and the characters on the desktop gradually disappeared. But for some reason, the names seemed to disappear in some order, and the next name would disappear after one name disappeared.

The first name to disappear was Aglaia, the goddess of light, in front of the beauty pageant champion Miss Mori Nana.

In less than ten seconds, most of the names on the desktop had disappeared.

Perhaps the fluorescent agent applied on the last few names could not hold on for long. Almost at the same time, the remaining names all disappeared from the table. Instead, a golden light slowly lit up on the main seat's table, and beautiful cursive characters gradually revealed their appearance - "Hecarte".

Goddess of the underworld, Hecate.

The ladies didn't like each other and had already chosen comfortable rooms with closed doors. Fortunately, there were many guest rooms on the second floor, so even if no one chose a room, there would be enough room for everyone. However, to ensure safety, Jinpei Matsuda found the largest room and took the two children, Gen Sugawa and Conan Haibara, to rest in it.

Although it is a rich man's villa, it is not one's own home after all. Living in such a room, Jinpei Matsuda is really worried about the privacy and security issues here.

Matsuda Jinpei was carefully checking the safety of the room from the outside to the inside. Sugawa Gen glanced at the clock hanging beside the bed and suddenly said, "I suddenly found a problem."

"What's wrong?"

"The woman didn't specify the duration of the game."

Matsuda Jinpei paused and threw the pillow on the bed. "It is indeed a problem."

"However, he pushed the man down on the sofa and said, "Don't think about it. We will know it eventually, right? Let's take a rest first. It looks like there will be a fierce battle tomorrow."

However, despite saying this, he could not help but feel a little worried. But as the oldest person here, he could not show his anxiety in front of these children. He rubbed Qichuan's head, lifted the sofa cushion, and checked along the sofa seam bit by bit.

"Hey, what is this?"

The two looked over and saw Conan squatting by the wall, carefully examining a dark brown spot on the wall. The wall was made of wooden boards, with a translucent brown hue, and the strange color block was not obvious on it. But Conan was the best at finding such subtle differences.

Conan pointed to the brown color on the wall and said, "The color of this place is so strange."

The brown color was a little black, and Matsuda Jinpei frowned. He lifted Conan away and bent down to identify the color block.

"How is it?", Sugawa Gen came up to him, his eyes stopped when they met the wall. Although a long time had passed, it seemed that this place had been cleaned up. But people who had come into contact with it could recognize what it was at a glance.

The two of them looked at each other at the same time, their expressions becoming serious. "It's blood."

At this time, Sugawa Gen recalled what happened at the art exhibition and understood what was going on: "Is this the massacre that Ms. Tanaka Takayama mentioned?"

This turned out to be not groundless. This villa really did hide some unknown secrets.

Conan tugged at the corner of Matsuda Jinpei's clothes, looked up and asked, "Hey, Officer Matsuda, can you tell us what happened here? We are really curious."

"It seems like you would have known it even if I didn't tell you," Matsuda Jinpei pressed his sore eyes and sighed helplessly, "Now that things have come to this, I'll tell you. You should also pay attention and never touch anything I emphasize."

He looked down at Conan and then at Sugawa Gen, and said meaningfully, "Do you understand?"

In fact, Gen Saikawa's curiosity is not that strong. The main reason is that every time Conan does something, he will involve Gen Saikawa. Over time, Gen Saikawa's impression in Matsuda Jinpei's eyes has plummeted, and he has become as troublesome as a child.

Seeing the two of them nodding busily, Matsuda Jinpei laid out the sofa cushions and sat down casually.

"In fact, this matter is no longer a secret among the police..."

Seven years ago, the Metropolitan Police Department suddenly received a strange phone call. A woman asked the police for help in a panic. Through the microphone, there were bursts of screams, children's crying and bursts of strange musical instruments.

The woman who called the police seemed to have been extremely threatened. Her mental state sounded very abnormal. She spoke incoherently and vaguely, and it took her a long time to spell out a complete sentence.

But through her sporadic use of ominous words such as "life-saving murderer", the police concluded that she was in danger.

After a series of shrill and terrifying screams, there was no sound on the other end of the phone. Fortunately, the call was not hung up, and the police quickly located the origin of the call through the signal.

However, to their surprise, they finally located themselves at the Huanghun Villa, a villa where an important exchange party was being held. This party was an exchange dinner held by the upper class of society, and those attending the party included business leaders and important politicians.

Realizing the seriousness of the problem, the police immediately mobilized a team. However, this place was built in a forest in the suburbs. The road was long and confusing, and it was impossible to tell the direction of the forest in the dark. In the end, when they arrived here, everyone in the villa was dead, corpses were everywhere, and blood was flowing.

The dead cannot be resurrected. This tragedy should have been made public and the whole of Japan should have observed a moment of silence.

But this incident is too serious. If any one person here makes it public, it will cause a lot of unrest in society, let alone dozens of people.

In order to avoid causing unrest, the higher-ups decided to suppress the matter and secretly investigate the cause of the incident.

It's a pity that seven years have passed and they haven't even seen a single person here, let alone any case.

Over time, the case was encrypted and put into the bottom of the file room. No one mentioned it again until recently when Matsuda Jinpei heard the name of Huanghun Annex again. His first reaction was that the tragedy would happen again. Therefore, he was very worried about Sugawa Gen coming here. When he first saw the waiter here, Matsuda Jinpei's first reaction was surprise.

Unfortunately, by the time he wanted to contact the police, it was too late. From the villa to the winding mountain road, the signals in these places were almost all interfered with.

"The piano room on the second floor and the painting studio on the third floor, these two places must not be visited."

Matsuda Jinpei stressed: "The test results at that time were true. These two places were the main crime scenes. I don't know what's strange inside, but you must not go there."

He glanced at the thoughtful kid and threatened him in a deep voice: "You know what will happen if I find out that you sneaked in -"

Conan was suddenly called out, and he gave a dry laugh: "Hey hey! I definitely won't go over there!"

Sugawa Gen chuckled, but quickly stopped laughing, a little confused, "But Takahashi Sakai and his friends came here to participate in the exhibition, and nothing happened."

"Well, Matsuda Jinpei knocked on the handrail, "It's a bit strange to say, although no one has appeared in this villa in these years..."

He paused and corrected himself, "Although the police have not found anyone in this villa over the years, there are regular art exhibitions here every year, and the champions of competitions from all over the country are invited to exhibit here, and these people have never had any accidents."

"So we often suspect that the massacre seven years ago was a horrible nightmare. We even wanted to let our guard down for a while, but the death list in the archives kept reminding us that things were not that simple here."

"We guess he's targeting a certain group of people and will let them off, like painters."

Conan shook his head. "But Mr. Hashiki Yu is also a painter, and those maids attacked him directly without showing any mercy. I don't think this is the reason."

After sitting quietly and listening, Huihara Ai said calmly: "No matter what, the incident happened at night. If there is something, there will be some clues tonight."

"It's useless for us to sit here and talk. So, take a rest and get enough energy to better face the fierce battle tomorrow."

Although she has the body of a child, she also needs beauty sleep.

Qichuan Yuan somehow understood what she meant, and smiled and spread his hands: "Okay, okay, it's time to go to sleep. I'll sleep on the sofa."

"However, Conan raised his head, and a cold white light flashed across his lens. "Those things happened at night, are you sure we can really sleep?"

Just as he finished speaking, there was a sudden eerie sound of piano outside the door, and the sound of some running footsteps. Gradually, bursts of dense conversations filled the corridor.

The people in the room tensed up, looked at each other warily, and tiptoed towards the door. The moment Jinpei Matsuda put his hand on the door handle, all the sounds in the corridor stopped abruptly.

It was as if someone was staring at them. A cool breeze blew through the gap in the door and into their sleeves, making their scalps tingle and giving them goose bumps all over their bodies.

They stood stiffly at the door. There was no sound in the corridor or the room. It was so quiet that only their light breathing could be heard.

There was a brief silence, and then a scream completely broke the silence.

“Oh no!”

Several people broke out and followed the sound. They came to the piano room at the end of the corridor. The door was wide open, and inside was a red-haired woman who was squatting on the ground with her back to them and covering her face.

People on the second floor kept rushing here. Matsuda Jinpei frowned and wanted to go forward to help this person up.

As if she heard his footsteps, Mori Nana screamed, "Don't come over here!"

Matsuda paused and asked hesitantly, "Ms. Mori, are you okay?"

Mori Nana lowered her head and covered her face in silence, without responding for a long time.

After a while, she loosened her hand, and drops of red blood dripped onto the carpet as she moved. She stood up staggeringly and turned her head expressionlessly, with a dead silence and suppressed madness in her eyes.

Everyone present couldn't help but gasp and feel nauseous.

The face that was so beautiful just now was now a bloody mess, the smooth skin was torn and the white bones could be vaguely seen under the flesh.

The messy scar clearly formed a few characters - つみ.
