Seeing the serious faces of Da Zhao and Zhou Ning, Xiao Qu was a little embarrassed, it seemed that her thoughts were dirty, so she quickly put away the remaining embarrassment and amplified her voice.

Zhou Ning frowned slightly and waved his hand.

"The video is played on the big screen, and the sound is adjusted to the maximum. Listen carefully to see what sounds are there. Don't reduce the noise, and the original sound will be played from the beginning."

Xiao Qu quickly followed suit, and now Peng Shinian, who was studying those bottles and cans, also pushed his glasses and came over, looked at the big screen, folded his arms and didn't say much.

The video was played again, and the ambiguous emotions of Da Zhao and the others dissipated, and they all stared at the women's reactions carefully. The ten-minute video was played to the end. At this time, there was a ticking sound from the door of the laboratory, and Zhou Ning turned around. By then, Xiao Qu had already paused the video.

Xu Dayuan, Xia Momo and Liu Yongxin walked in quickly. Xu Dayuan took a glance, his eyes fell directly on the big screen, he stopped, and looked directly at Da Zhao.

"Stinky boy, what are you doing?"

Da Zhao had a constipated expression, and spread his hands with a look of grievance.

"I said leader, there are a lot of people in this room, why are you staring at me and yelling at me? I just don't pay attention, and it's impossible to bring these people to watch AV movies together in the laboratory, right?"

Xu Dayuan coughed, Xiao Qu hurriedly minimized the video, Xia Momo didn't say anything, walked directly to Zhou Ning, saw a strange face, and glanced at Peng Shinian.

"This is the double doctor?"

Zhou Ning stood up and introduced Xu Dayuan and the others.

"Peng Shinian is also a student of my teacher, Professor Li Chengbin, with a Ph.D. in biology and entomology. Da Zhao nicknamed him Poet, and I liked him quite a bit.

This is Xu Dayuan, the deputy director. I introduced it to you before, and my master Liu Yongxin. This is my girlfriend Momo Xia, who is also one of the project leaders of the Qin University R&D Center. You can call him Teacher Xia. "

Peng Shinian hurried forward, stretched out both hands, made a gesture, and put away his left hand. Xu Dayuan smiled and held Peng Shinian's hand vigorously.

"Welcome to join A Poet!"

Liu Yongxin and Xia Momo also came over to express their welcome. After some introductions, Peng Shinian took a few steps back. He knew what happened in the video just now. still necessary.

Zhou Ning glanced at Xia Momo, walked over, rubbed his nose and said:

"How about you go to my office to take a rest, drink some water and lie down for a while, let's study this case, I don't want you to see this man hehehehe."

Xia Momo nodded, she didn't talk nonsense, took Zhou Ning's key and went out directly.

As the door closed, Da Zhao let out a long breath, and quickly told the whole story without any exaggeration. After speaking, several people looked at Zhou Ning. Zhou Ning took Xiao Qu's mouse and found a section of the woman's face. Press Pause at the position of the internal feature, the little song is clear, quickly take a screenshot, and then quickly zoom in on the picture.

Liu Yongxin walked to the big screen, stared at the picture for a long time, turned his head and said in surprise:
"The girl is dead!"

Zhou Ning nodded, pointed to the picture and said:

"The video was played twice, and the original sound was played directly without noise reduction processing. There were only male voices in it. There was no response from the female, and there was no breathing sound. Most of the deceased's face was covered by hair. This shot was the most exposed. Only part of the left face can be seen.

Looking at this position, there are indentations on the cheekbones of the deceased, and faint corpse spots can be seen on the side of the neck. In addition, it seems that the skin on the mouth and nose is light in color, and there are ecchymotic bleeding spots around the lower eyelids. In the previous picture, the male pinched When a woman’s lower jaw is closed, her mouth is slightly opened, revealing the gums, and there are rose teeth on the neck of the teeth【1】.

So this woman has died, within 48 hours of death, the deceased's limbs were not obvious, and it felt that the rigor was deliberately destroyed. The cause of death is suspected to be suffocation caused by covering the mouth and nose. "

Liu Yongxin kept nodding at the side, obviously agreeing with Zhou Ning's judgment, but he still sighed.

"Unfortunately, the light in this picture is too dark, and many details cannot be judged. There is only such a part of the face of the deceased, and it is impossible to search with software, right?"

Xiaoqu sighed.

"I have already intercepted the picture, and adjusted the female's face to a horizontal state according to the proportion, and simulated the other side according to the same proportion, but her eyes are closed, which lacks 50% of the comparison points. Search The result was as high as more than 7."

Xu Dayuan rubbed his nose, stared at the screen and waved his hands.

"I contacted Liang Hong just here. They must have more information about the website than you. As for the video, you should study it carefully. It can't reduce noise, analyze the man's accent, and other characteristics. Especially this room, it doesn't seem to be like a hotel.

In addition, there must be a reason for these people to upload these videos to this website. Is it because posting videos can give money, or what?If it is settled, can I inquire through the bank payment information? "

Xiaoqu sighed.

"This is what makes people puzzled. This website is not for profit, and the registration information is only an email address. It is a sharing platform, and there is no current account query. Now the uploader's information is only Tom's email address, and his name is Stoll. .”

Xu Dayuan dialed Liang Honggang's phone number, told about the discovery here, and hung up the phone after a while.

Zhou Ning gestured to Xiaoqu, and played the video again. This time, everyone wanted to hold up the magnifying glass to observe. When it was playing for 7 minutes, Da Zhao took a picture of Xiaoqu, and Xiaoqu quickly paused.

He pointed to a promotional poster on the exposed corner above the wall. Below it was only a skull and a line of ONE PIECE, followed by an akimbo hand, and part of the red dress. Next to it was a woman's waist, and said:

"One Piece, this is the promotional poster of One Piece 2012. Don't worry, I'll look for it. I seem to have this one. It was not easy to find at that time."

As he said that, Da Zhao opened the phone album, searched for a long time, and held up the phone to show Xu Dayuan and Zhou Ning. Sure enough, the corners were exactly the same, and it was indeed a promotional poster of One Piece.

However, such a poster can't explain anything. After all, the circulation is impossible to estimate. It can only prove that the owner of the room likes One Piece.

Zhou Ning looked at the big screen. The lights in this room were not on. It seemed that only a wall lamp was on on the right side of the bed. A control panel was made on the wall next to the bedside table under the lamp. There were light switches and track sockets. It was comparable to that of a five-star hotel. that kind of design.

At this time, the camera is in the paused state facing the left side. This bed looks 2*2.4 meters, very large, and the white sheets have dark vertical stripes. The brocade sheets are of very good quality. There are two white pillows of the same style.

The head of the bed is a classical European-style bed, and the video is on the left side, and you can see a part of the window. There is a bedside table between this bed and the window. The two layers of curtains are not fully closed. The curtains cover most of the windows, and the light outside the windows is dim.

But it wasn't night, it was just dark.

Outside the window, the silhouette of a part of the shadow looks like a pointed building, and the edge of the gauze curtain seems to be blown by the wind because the window is open, and you can see leaves shaking outside the window.

After careful identification, it seemed that he did not see the tree trunk. Zhou Ning paused, and quickly turned his head to look at Peng Shinian, who was watching the excitement.

"Poet, can you tell what kind of tree it is by looking at the leaves?"

Peng Shinian came closer and let Xiaoqu rewind the video, almost playing it frame by frame, and then Peng Shinian stood up directly.

"This is not a tree!"

Zhou Ning paused, and Da Zhao also looked surprised. In the video, the leaves trembled violently, as if they were blown by the wind. After all, the window screens also fluctuated.

"It's not a tree, what is that?"

Peng Shinian pushed his glasses and said seriously:

"This is ivy, which is native to Europe, Asia and North Africa. It is a small shrub plant of the Araliaceae Hedera genus. The leaves are generally triangular-oval and differentiated into entire or three-lobed. This one is three-lobed."

Peng Shinian stared at the shadows of the swaying leaves, introduced them endlessly, straightened up after speaking, and found that Zhou Ning and the others were all staring at him. For a few seconds, his mind was a little blank. There was no problem, but such an action still made him a little puzzled.

"how?"

Da Zhao coughed, put his arms around Peng Shinian's shoulders, and said earnestly:

"I said poet, I know that you are a double doctor and have real talents, but you have to think about it. The people who listened to your explanation, the highest level of understanding of plant knowledge is in the category of pistil and stamen. What are you doing? What is the Three Cracks, can you tell us whether we understand it or not, which is the favorite sentence of our leaders, is it okay to speak human language?"

Peng Shinian laughed, talking about people's words, when chatting in the morning, Da Zhao just told him the reason, he instantly understood Da Zhao's meaning, put his hands together quickly, and then said quickly:
"It's very simple. This plant is found in many places in Qindao, especially those century-old ancient villas by the sea, or some old houses with less human interference. Many of their exterior walls are covered with green vines. These are ivy."

Zhou Ning narrowed his eyes.

"Old house? Villa?"

As if thinking of something, Zhou Ning put his hand on Xiaoqu's shoulder.

"Process the screenshot. The pointed building in the distance outside the window seems familiar to me. You can adjust it. I want the contrast to be stronger. See if you can deny it. Where is it?"

As soon as I heard Xiaoqu, I was invigorated, and I quickly clicked on the operation. The color of the screenshot was constantly changing. With the adjustment, the sharp black building outside the window became clearer and became a completely black comparison picture.

It is no longer necessary for Zhou Ning to adjust to such a degree. Da Zhao leaned over and widened his eyes in surprise.

"I'll go, adjust it to this level, I don't need to look at it, I know it's the Customs House, with a pointed roof, I thought it was St. is flat and cannot be seen from such an angle."

Having said that, Da Zhao frowned and glanced at Zhou Ning.

"I said, it's irrelevant to find the three points now. In Quanqin Island, there are many houses that can see the Customs Building. As for the wall-climbing tiger, as long as the old communities by the sea basically have this thing, after all, this thing If the shoveling is not clean, it can still take root and sprout by itself in the second year, so there is nothing to say about the One Piece poster, right?"

Zhou Ning shook his fingers.

"Each one is very ordinary, but the three together are not ordinary, at least point us in a direction."

Xu Dayuan's eyes lit up, as if he had thought of something.

Rose teeth are the stained teeth of the suffocated deceased due to bleeding from capillaries in the gums and mucosa caused by hypoxia during the suffocation process. Rose or light brown red can appear on the surface of the neck of the teeth.
