Jin Yi listened to the voice, the drum beat in her heart began to speed up, and she walked upstairs with light steps.

Following the voice, she walked to the innermost room in the corridor, and every step she took in the empty corridor was a soft echo, as if someone was following her.

Holding his breath, he finally walked to the door of the sound source, and saw a woman with long black curly hair, a narrow face, and big red lips hitting the simulated limb with a crowbar in different directions.

In front of the woman were seven or eight mock limbs, and behind her were different weapons, clubs, knives, crowbars, shovels, and so on.

Jin Yi felt her scalp tighten, because every time the woman hit, she would show a very crazy and happy smile. At this time, the woman also noticed Jin Yi.

"Who are you? How did you get in? When she saw the woman who was not invited, she immediately sank her face and looked at Jin Yi with dark eyes.

"You are Sister Lu, I am Jin Yi, who is new today, and I will live here in the future."

"New here, come on, little girl, show you my sister's new discoveries." After saying that, Lu Na immediately showed a smile and beckoned Jin Yi over.

She said happily, "You don't know that the corpse that was dug out of the ice lake, they thought the murder weapon was a shovel, but in fact it was not at all, it was a crowbar." Because they found a bloody shovel near the scene, they thought it was a spade, and they didn't have to think about it, how could the murderer leave such a big clue if he handled the scene so cleanly. ”

Luna said, lighting a cigarette. To be honest, Jin Yi looked at her at this time, she didn't have a charm, after all, she looked pretty good, and her half-leaning posture of smoking on the table was even very charming, a little sad and a little charming, like a woman who had experienced the wind and dust.

At this time, she didn't look like a neurotic forensic doctor.

Immediately, she began to nibble on the filter cotton of the cigarette, and her crazy expression was displayed again, Jin Yi knew that Lu Na was abnormal, but the scene in front of her still made her feel uncomfortable.

"I'm right, but sometimes these people don't necessarily believe it, believe it or not, anyway, the limbs can speak, and the autopsy report has to be issued by me.

Do you know why they don't believe? Runa knocked her cigarette ash and looked at Jin Yi.

Jin Yi shook his head.

"Because if it is an injury caused by a crowbar, the prisoner cannot be found, there is nothing at the scene, and there are so many onlookers, it is difficult to solve the case. But the spade is different, because there are clues about other people on the spade. ”

"It's not ...... Could it be that the wrong person was caught? Jin Yi frowned and looked at Luna.

"Isn't that what you're talking about? But these calves, this kind of thing is not this time, I have done it before, damn, I get angry when I think about it. ”

"No, Sister Lu, who are you referring to? Is it someone from our bureau? ”

"You're still young, you don't understand, you'll find out later. We workers sometimes can't do anything. ”

"Sister Lu."

"Forget what you heard today, we will be neighbors in the future, neighbors of the Secret Case Bureau."

Lu Na's voice came, Jin Yi was surprised, and saw Lu Na look at the tea knife on the table again.

Jin Yi approached and asked softly, "This is the tool of the 'Rose' case?" She observed that the silver tea knife had a black pattern like water waves, which was unique to Damascus steel.

"Yes, the murderer is a ruthless man, with such a good guy. Do you know why he chose this knife? ”

"What is the psychological problem?" Jin Yi did not understand the particularity of this tea knife.

"I suspect that the murderer must have said something to the deceased before the killing, because the people who died under this tea knife were extremely frightened. Then when the deceased was most afraid, the murderer used this tea knife to kill with one sword.

You look at this pattern, forming microscopic sawtooth, so the weapons forged from Damascus steel are very sharp, and this is the king of cold weapons that is all the rage. It's just that the times have developed and buried its former glory.

If you want to come to 'Rose', you should be a more retro person. ”

"Yes, after all, this knife is much more expensive than a gun, I heard that the murderer is from the north, so the possibility of a gun should not be ruled out."

"But she really hasn't used a gun, and I heard that the cases in the north were also this kind of knife."

"Individuality, willfulness." Jin Yi sighed.

"Rich." Luna sighed.

As the two were talking, they heard the sound of something dragging in the hallway.

Luna shouted outside the door, "Lao Jing, what time is it, you still haven't slept yet?" ”

At this time, Liu Jing walked in the door, Jin Yi had seen her, the one in the reference room, but the scene was a little embarrassing at that time.

Liu Jing glanced at the things in front of them, and said slowly, "You can't finish knocking at night, how can you sleep." ”

Her voice is very special, a little low and hoarse, but her pronunciation makes people feel very pleasant and elegant, which surprises Jin Yi. Just looking at her sloppy appearance, it's really hard to associate with this kind of voice.

When she spoke, Jin Yi was reminded of the nobility of the upper class of Western Europe, that lazy and low feeling.

Immediately, Jin Yi looked at Liu Jing carefully for a while, and her heart was indescribably weird.

"In the past, the office was turned upside down, and I didn't see you delaying your sleep." Lu Na glanced at Jin Yi, and then looked at Liu Jing.

"Did you make any new discoveries?"

"The real murder weapon was found in the reservoir case, but it was not found at the scene."

"The murder weapon that was not found at the scene was not a murder weapon. If you can't catch a suspect, you're not the right suspect. Liu Jing smiled contemptuously, and in the blink of an eye, Jin Yi saw her wearing brown contact lenses. Immediately, she walked out and waved her hand with her back to the two, "Go to bed early, after all, you don't have my life to go to work and sleep." ”

"Why do you need to sleep for a long time before you die, you will sleep forever after you die." Runa snuffed out the cigarette butt with her fingers and smiled.

Liu Jing didn't speak anymore and disappeared from Jin Yi's sight.

Immediately, Jin Yi said goodbye to Lu Na and went back to the dormitory to rest.

Jin Yi's room has a bunk bed, the upper bunk is unoccupied, and there are a bunch of sporting goods. She really couldn't imagine what these things had to do with the Secret Bureau.

There was a desk next to the bed, and when I first came, the desktop had fallen a lot of dust, which had been wiped clean with the help of Qiao Jinyuan. There was a very ordinary eye-protecting lamp on the table, and there were two drawers under the desk, the first of which contained a leather paper drawer with a key in it.

Jin Yi studied it for a while, and it felt like the key to a cabinet, so he didn't care about it and threw it back.

In the drawer on the second floor, there was a book called "Good Angels in Human Nature".

Jin Yi opened the book, and it seemed that someone should have read it. She looked at the cover again, this was the first volume, and the subtitle was "Why Violence Decreases".

The author is Steven Pinker, a well-known cognitive psychologist who is a professor of psychology at Harvard University and a former professor of psychology at MIT.

Jin Yi flipped through the introduction on the book, and a subtle feeling struck. Why is there such a book here? Who lives here?

She flipped through the contents of the book, and it felt as if someone wanted to tell her something through such a book.

Just as she was thinking, there was a knock on the door, and Jin Yi opened the door, which turned out to be Luna.

"The five groups of guys are back, they bought a lot of food, do you want to have a supper?"

Jin Yi didn't have the habit of eating supper, but it was rare for a colleague to invite, so she happily went, and when the two of them went downstairs, the sound of Luna's slippers "clicked" echoed in the corridor, and she said as she walked, "Little girl, do you know?" Can the body speak? ”

"What do you mean, Sister Lu, do you mean that the clues are all on the body?"

"Of course, it's all on the limbs, and the traces on the limbs are the clues. It's just that some people don't like to believe it. Runa sighed.

Jin Yi could hear that there was something in her words. At this time, Jin Yi suddenly remembered the mysterious letter on the desk ten years ago.
