Pan Lei came to the window, but only saw houses, trees, flowers, and rivers, but there was no other trace.

"Captain Xiao, what are you looking at? Watch so fascinating? Pan Lei couldn't help but ask.

"Don't you think the scenery is beautiful?" Xiao Yong replied.

"I don't think so!" Zhang Wei was behind and said leisurely.

Then, he took out another small bottle and began to fill it with air, and when he was done, he put the label back on.

After completing a series of actions, he looked at the windowsill and said, "Something is wrong......"

Xiao Yong asked very cooperatively, "What's wrong?" ”

"See any traces here?" Zhang Wei pointed to a place on the tiled window sill that was no different from the other places and said, "Here, there is a very different trace, the color is 5% darker than the surrounding area." It means that there was something here that blocked the sun, which caused the place to be unevenly sunburned. ”

Pan Lei and Xiao Yong lay down and looked at it, and vaguely noticed the difference.

Then he looked at the sun again and said, "The position of the head is darker, about 7%, and the end of this will be lighter, about 3%, and then calculate the angle between the head and tail and the sun...... There must be something 13 to 15 centimeters tall here, I speculate a plant. ”

Pan Lei shrugged his shoulders and said, "You are amazing, you are right in everything." ”

The young policeman was surprised and said, "You have observed this with the naked eye?" ”

"Of course...... Is there any instrument here? ”

"Uh, it's amazing......" the policeman exclaimed,

"Could it be that someone came here again after the crime and took the plant away? Does it also mean that this plant is the culprit that caused his death? ”

"Very likely!" Zhang Wei nodded and said, "Go to the top of the building and take a look, if you can find something else." ”

They went up to the top of the building not to find nothing, but to find too many!

There are clothes, there are cupboards, there are toiletries, there are chairs......

"These things seem to be daily necessities, and they are very new!" Pan Lei flipped it casually and said.

"And it's a woman's daily necessities." Zhang Wei added.

"There! Something seems to be in the place where it is blocked by clothes? The young policeman said as he walked over.

"Be careful!" The older policeman hurriedly followed.

But there is no danger, just a portrait of a woman.

The woman on the picture, smiling, does not give people much glamorous feeling, but is indescribably gentle and moving.

In the lower right corner of the portrait is a line of text: "Self-portrait of Chaoping on April 10, 2009 Chen Keke"

"Chen Keke, that's right, it's Gu Chaoping's ex-girlfriend and the crush of Professor Smith." Pan Lei said.

"Are these things all this Chen Keke's? Gu Chaoping was also ruthless, even if he broke up, he threw away all her things. Xiao Yong shook his head and said.

"Maybe there are other hidden secrets......" Pan Lei only said half of the words.

turned his head, but saw Zhang Wei lying on the edge of a roof.

"Zhang Wei, did you find anything?" Pan Lei followed.

"Of course, look at this!" Zhang Wei pulled on the ground for a long time, and finally found a withered plant, "This should be directly above Gu Chaoping's window." Do you know this plant? ”

"It's a lot like a clover, but it's bigger than the leaves of a clover." The older policeman said with some uncertainty.

The young policeman added: "It's quite common on the road, and sometimes purple trumpet flowers bloom. I just don't know what it's called. ”

"You're only half right. This is indeed a type of clover, this is indeed a weed. But he has a name - sorrel. I just don't know what the specific breed is. After saying that, Zhang Wei took out two small bottles from Baolin, one for collecting this kind of air, and the other for this withered sorrel.

"Alright, there's nothing new to discover here, let's go, let's go to the next location, the mental hospital. Thank you for your cooperation! Pan Lei shook hands with the two policemen again.

"I'm sorry, it didn't help much." The elder police officer.

"Expert Pan, when the case is over, let's go eat roast duck together, I'll have a treat!" The young policeman said.

"Good! When the case is over, we'll make another appointment. ”

After just ten minutes of driving, the three of them arrived at the mental hospital.

The receptionist was a director, but after hearing that the person we were looking for was Chen Keke, he shook his head.

"She's dead, isn't she?" Xiao Yong asked.

"Of course not. She has a strong desire and fear of attack, and has been locked up in the basement by us. Don't get me wrong, it's not a restriction on personal freedom, but her situation is really special, come with me! ”

Following the director, they came to a small square bungalow. There are more than a dozen monitors showing the conditions of different mentally ill people in the basement of the prison.

Pan Lei glanced at it and felt a little uncomfortable.

Some were tied to the bed, and their faces were extremely hideous. Some of them kept hitting the elastic wall with their bodies, but they didn't know if they wanted to break it or let themselves die. Some use paintbrushes to constantly draw strange patterns on the wall. Some of them are just wandering around, like ghosts.

And the last one ......

"The last one is Chen Keke."

The three of them huddled in front of the display screen and began to look at Chen Guoguo's situation.

She seemed to be just walking aimlessly around the room, and there was nothing out of the ordinary.

"Look at the walls!" Zhang Weidao.

The two men stared at the walls.

I saw that there were many dark red paintings on the walls. If you look closely, you will find that there are faces with the same eyes and huge eyes!

"She's just looking for a blank space on the wall to paint." said the director.

Sure enough, she noticed a relatively empty corner on the side of the wall, so she stopped, opened her mouth, bit her finger, and continued to draw there with blood.

After drawing another big-eyed man, she stood up satisfied, then suddenly turned around and stared at the camera.

Pan Lei: They were all taken aback.

I saw that her face was miserable white, but her eyes were twice as big as ordinary people! His mouth was wide open, dripping with saliva......

If you think about the self-portrait of her, it looks like two extremes.

"When she sent it, she became like this?" Xiao Yong asked incredulously.

"yes, it's been over a quarter. All she did every day was to paint this big-eyed horrible face repeatedly. But we didn't dare ask. ”

"These big-eyed people of hers seem to be quite round...... Director, do you know what these big-eyed people mean? Pan Lei asked.

"I don't know." The director shook his head.

"Is it impossible to communicate?" Zhang Wei asked with some regret.

"Yes, there is no more information." The director said with some embarrassment.

Thinking back to the self-portrait, and then looking at Chen Keke, who was judged to be two people in front of him, no one was a ghost or a ghost, the mood of the three people unconsciously fell.

"Can we go and try communicating?" Pan Lei said.

"Are you sure?" said the director.

"Don't let go of all clues." Zhang Wei said.

"Okay, I'll arrange it."

Ten minutes later, Chen Keke was sent to the communication room with his whole body tied.

Her face was angry at one moment, horrified at another, smiling at another, and crying at another......

"Your name is Chen Keke, right?"

Xiao Yong asked this three times.

Chen Keke, who was on the other side, suddenly raised his head and said, "I'm a ghost!" I'm a ghost ......."
