Xin Pet drove Ye Shichao home, her home is in a high-end community near the office, thirteen floors are finely decorated, and the standard single aristocratic apartment.

The door lock has a double guarantee of fingerprints and voiceprints, which seems to be very rigorous, but the door opening instruction turned out to be "open the door with sesame seeds", which is really a bit naïve, so that she was very weak when she unlocked the lock, her voice was fluttering, and the voice-controlled lock was very dedicated to saying "the voice does not match" three times, and finally she was angry and yelled "open the sesame door", and the door was opened.

Xin Pet pushed the door open, and looked back at Ye Shichao very nervously, but fortunately, Ye Shichao didn't seem to be interested in these little things, and still looked indifferent and followed her into the door.

"What do you want me to do at your house?" Ye Shichao looked around her living room, the living room was decorated, obviously a good designer was hired, and the soft decoration also tried its best to create a warm atmosphere, white gray curtains, warm brown carpets, white sofas and green cushions, the texture is very good. It's just a little messy, the ornaments are not in their original position at all, and there are even a bunch of washed and unfolded clothes on the sofa.

Seeing Ye Shichao's eyes fall on her pile of clothes, Xin Pet hurriedly rushed over to pick up the clothes, threw them into the bedroom, closed the bedroom door, and closed the side bed by the way, and then said, "I've been too busy lately...... Usually I still love to tidy up. Ahem...... Come with me to the study. ”

Xin Pet's study is not big, there is no trace of elite strong woman atmosphere at all, whether it is a bay window that can be used as a bed to sleep on, a lazy sofa that can lie down, or a white mobile desk, it is completely for lazy people, she has given up struggling, her face does not change, she walked to the desk, opened a folder in the computer, and pushed the screen over to Ye Shichao to see.

"When I was taking the criminal psychology course, my junior and I once collaborated on writing a paper on this case, and I collected a lot of information related to the case for the paper, I hope it will be helpful to you. ”

Ye Shichao walked over and looked at the computer screen, it was indeed the detailed information of this case, the clues of the case announced by the police, even including the news in newspapers and magazines, and the gossip that the reporters who wrote the hunting report did not know where they heard it, it was very detailed.

But most of them are known to Ye Shichao, after all, after so many years, he has not only bothered to save the crime scene every day, but also tried his best to investigate it well.

There is one piece of information that the police did not mention, that is, he is actually the first person to find the body of "Beisen".

Even after so much time, he still remembers the events of that day clearly, as if carved into his soul.

It was a different evening than today......

Yes, that day, it was dark early in the morning, the dark clouds were densely pressed from afar, obscuring the last bit of light of the sun, the sporadic light of the street lamps was scattered on the long street, the light was faint and a little pitiful, and the pedestrians on the street hurried home, for fear that they would walk slowly, and be drenched in soup by the heavy rain that would fall at some point.

Ye Shichao mixed in the crowd, hunched his waist, protected the things in his arms, from being seen, lowered his head and went into the alley, he was ten years old, he was still a child, wearing the uniform of the nearby elementary school, like all the primary school students, thin and long, he didn't look very inconspicuous, so no one noticed him. He walked down the alley with his head down, turning around and coming to a room with a wooden sign that read "Violinist's Workshop".

It was a very ordinary house, with vermilion old brick walls, a stone staircase at the doorway, and a vermilion gate with a toothy and clawed door god on it. It's almost like the one next to it, and then the one next to the house, and then in front of the house, which is almost like a copy-and-paste level.

Ye Shichao has been here many times, ran up the steps with a familiar way, knocked on the door, and took a breath before shouting: "Mom, I'm here with fireflies." ”

This is the house that her mother rented, and she usually makes violin here, and when she sees a guest who makes a violin, she never brings her work home, and she never sees her at home, she smiles very gently, but when she hears that it is very serious and eccentric here.

The door was quiet, no one answered, Ye Shichao looked down at the glass bottle he had been holding in his arms for a long time, and lifted the corner of the black cloth covering the bottle, revealing a little fluorescence inside, which looked particularly beautiful in the dark alley.

He laughed and knocked on the door again, this time with a little hurry, and with great strength, the door squeaked and opened by itself.

I didn't lock the door, this really doesn't look like my mother's style, my mother is very precious to the tools and materials here, very cautious, every day the door of the studio is locked tightly.

He frowned and looked in, the lights in the makeshift bedroom and living room were turned off, except for a small light in the direction of the production room. He walked in with the bottle in his hand and called tentatively, "Mommy." ”

Still no one answered.

Did you fall asleep in the production room?

Thinking wildly, he had already walked to the door of the studio, the door was hidden, and the dim light showed inside, and the fragrance of wood, he liked the smell very much, and thought about what kind of surprised expression his mother would have when she saw the fireflies he raised, so he laughed, sniffed and pushed the door open, and was greeted by the nightmare that haunted him all his life.

The workshop was full of wood, and on the walls hung the violins that had already been made, and the ones that were painted for drying were supposed to be placed in the window, but they fell to the ground, apparently from falling down, and the fall was so hard that wood chips jumped everywhere.

It was a picture he was all too familiar with, except for the head floating under the beams.

It's Mommy's head.

His face was swollen and bruised, his eyes were protruding, and his neck seemed to have been cut by a sharp blade, and even dripping blood.

Underneath her head was her body, a headless body, lying quietly on the ground covered with sawdust, blood splashing all over the ground, and bloody air rushed to her face.

Ye Shichao was so frightened that his whole body froze, he couldn't shout, the glass bottle in his arms fell to the ground, and he fled in a panic in the fireflies that had been suffocated for a night, and a few of them fell on Beisen's hair.

Her long hair was braided into her favorite braid, with fluorescent dots on it, hanging in the air, and the picture was eerie and beautiful. He was not afraid, and the ghost walked in and looked up at her open eyes.

"Mom. He seemed to be talking, and he didn't seem to make any sound, "What's wrong with you......?" he wanted to step forward, to hug his mother and shake her awake, but he didn't know whether to hold his head, or lose his head?

I don't know if the head hanging above his head heard his cry and shook it, and the fireflies were startled, and a dead butterfly spun and fell from the top of her head.

He picked up the dead butterfly and placed it in the palm of his trembling hand.

He has been recognized as a weird child since he was a child, he doesn't like toys, he likes to study all kinds of insects, and the habits of various insects are like a few treasures, although he is not familiar with this kind of butterfly, but he has seen it in books.

Half of the wings are beautiful faces, and the other half are skeletons. This is the famous "Kashin Ghost Beauty Butterfly".

A very rare poisonous butterfly, as rare as a gemstone, but with a very strange legend. Legend has it that anyone who catches this butterfly will be cursed and die a mysterious death, and the death will be tragic.

He looked at the beautiful face on the butterfly's wings, there was a wind blowing outside the window, the butterfly seemed to move, and the beautiful skeleton moved together, and pounced on him with a cruel smile......
