Outside the window of the library is a small artificial lake, which is overgrown with fine bushes, and the annoying sound of insects never sleeps, day and night.

Lintor raised his chin to admire the depressed lake, wanting to peek through the barrier of green algae to peek into the secrets of the bottom of the lake.

"Why was it that the disappearance of many years ago was discovered through a drawing of a person? Is this just a coincidence? He asked.

Figley threw out the long-prepared answer: "It is definitely no coincidence, that wetland park is a free leisure place open to the public, and for so long, no one has thrown such a large piece of drawing paper into the water." ”

He added that the person who threw the paper was most likely the person who had been the victim of the disappearance, which was undoubtedly a provocation to the police officers.

"It's been so long, and the murderer still misses the remains?"

"He may also be in the know."

A few people walked into the reading room, and the air suddenly fell silent. Linto's eyes were fixed on the writing, and Figley also tacitly chose not to speak.

Just a few minutes ago, Lin Yin, who had not been seen for a long time, brought good news and bad news at the same time, she said that Marianne's ability to see the soul has a certain relationship with the temperature of the human body. Because her own body temperature is low, she can sense individuals with a higher body temperature than herself.

However, this ability is fading, and they find some marks of abrasions and burns on Marianne's body, and once her ability is completely gone, her life will be exposed.

There was no reason for them to restrict Marianne's movements, allowing her to move around as she pleased, but she needed to be accompanied by medical staff.

Even in this case, during the free time after breakfast at eight o'clock today, Marianne was lost, and she could not be found in the whole campus, I am afraid that she was outside the school.

Lin Yin's words made Figley and Linto worry that there might be some important reason for her departure.

They hurried to the gate of the university campus, where Lin Yin, who was wearing an overcoat, was already waiting. Marianne had any electronic devices on her body that could communicate, which meant that it could only be found by human power for now.

They decided that one of them would go in one direction, start along the outer wall, and finally meet at the back door. Linto entered the campus alone and searched aimlessly, thinking that the school was so big that Marianne's grandmother should not be able to go that far.

There was also a doorman at the school gate, and he could guarantee that the students at the school must have seen this blind old woman, and of course, this must be accompanied by the premise that she had been to the campus.

Linto asked three students he met on the road, and the answers were unsatisfactory. Maybe she really didn't come to campus today, but she must have been there before.

The campus is separated from the science laboratory by an iron railing, and there is an access control system on the front, so students are only allowed to enter during classes and visits. Linto was a special case, and he had to work hard to see his father.

Today was a bit of a special situation, as Lintor bypassed the parking lot on the right and walked along the winding greenway towards the eight-story building in front of him, the huge solar panel above him shining brightly.

He lit up the call panel on the door, and Professor Lin's clear voice was electronically controlled to reach his ears.

"What's the matter?"

"Dad, has Granny Marianne ever been to you?"

"I've been here, I've been with her for a while, what's wrong?"

"Do you know where she is now?"

"I don't know, she didn't say anything when she left." Professor Lin was slightly silent, "About an hour ago, a researcher told me that she had lost it. ”

"yes, but what did you say?"

"Oh, she complained to me that Old Deng treated her like a guinea pig, so I comforted her a few words, and that's it."

"You should pay more attention in the future, she has depression."

"Okay, I'll pay attention, I'm really afraid that she will do something dangerous."

Linto was shocked: "You say, again? ”

"Because she can't see with her eyes and doesn't know what others think of her, maybe she is a weirdo in the eyes of others. Such an old man lives alone in an empty house, with no friends or relatives, and no one will be surprised if he suddenly leaves one day. ”

Linto shouted in his heart, how can you say that?

You are wrong, people do not necessarily have people to rely on to survive, and you can't see her enthusiasm for life at all. We are all her friends, and we would like to be her loved ones if we can.

Linto had no grandmother, who died when he was very young. In the past, my grandmother used to hold him in bed at night before school and tell him many stories, such as the evil ghosts in the mountains and the howling werewolves, and he still remembers them to this day.

So, when he saw Marianne, he thought of his grandmother again, and the gentle smile she had on the wooden chair.

"See you later." He resolutely cut the connection.

The so-called estrangement will slowly grow with age, and it is the first time he feels this pressure.

If you think about it, could it be that Dad's comfort didn't work, and Marianne still wanted to avoid it? But listening to Lin Yin, Professor Deng didn't treat her as an experimental pig, and Marianne did what he said from beginning to end, in the final analysis, she was the only one who felt this way.

There is a waste storage area at the back of the laboratory building, which is used to store those scrapped chemicals and damaged laboratory equipment, etc., and they have a special conveyor belt to transport the packaged foam cartons out of the building, and then the relevant manufacturers will recycle.

The yellow warning sign was particularly eye-catching, and Linto didn't know there was such a place, it was like a low little black house, with a large gate more than three meters high facing the road. There's a lifeless smell to it, like the abandoned back garden of a hospital, with weeds taking over the former lawn.

He looked at the electronic door on the side, huh? Strangely, it may be the negligence of the custodian, the door is not locked.

Linto walked over and looked through the lookout window, and was immediately frightened by the scene before him.

By the light of the fluorescent lamp, he saw two people inside, one of whom was standing with his head down, unable to see his outfit clearly. Another of them fell right in front of him, a bright knife stuck in his left abdomen......
