last case

"noob."

Tang Xin came over in a hurry, he still had his glasses on, and when he saw Xie Ji Bai, he immediately said, "I seem to have discovered something here."

Xie Jibai said: "I also found out. But now I need to go out immediately."

Xie Jibai was going to pick up the courier, told Bi Chengyuan, and set off immediately.

Although Tang Xin didn't know where he was going, he seemed very anxious and ran out without asking.

Tang Xin drove the car, Xie Jibai showed him the way, and the two went to Chen Wanting's parents' house.

Xie Jibai's family used to live there, next to Chen Wanting's parents' house, and they were neighbors.After I moved away, I didn't go there very often.

Chen Wanting's parents were very kind to Xie Jibai, because they were neighbors, and they had a good relationship. Since Xie Jibai's parents passed away, they felt even more pitiful for him. They originally wanted Xie Jibai to live with them.But Xie Ji Bai didn't want to disturb other people's lives.

The road is not very far, but it is not too close. While in the car, Xie Jibai told Tang Xin about the delivery.

Tang Xin was very surprised. After all, no one thought that Chang Lao would send a courier to Xie Jibai's home.

What is in the express, they have no idea.

Xie Ji Bai is not sure whether this death of Chang Lao has anything to do with it.

"Xiaobai." Tang Xin said, "I also have something to tell you here."

"What?" Xie Jibai said, "Is there any result of the autopsy?"

Tang Xin nodded and said, "According to the results of our autopsy just now, Mr. Chang probably committed suicide and hanged himself."

"What?" Xie Jibai was taken aback, and said, "Suicide?"

Xie Jibai also seemed to find this possibility very inconceivable, why did Chang Lao suddenly commit suicide?What is the reason.

Tang Xin said: "Although it is unbelievable, this possibility is very high. Chang always hanged himself and suffocated to death. During the process, there was only a stress reaction, but there was no great struggle. If Chang always was strangled If he died of suffocation on the neck, then he should have signs of struggling, and all aspects of the body's reactions are wrong."

Xie Jibai said, "Is it possible that he died in a coma?"

After he finished speaking, he also felt that it was impossible. When Chang died of old age, his eyes were not closed, and there was an expression of forbearance and pain on his face.

Tang Xin said: "When Chang died of old age, he should be in a lucid state. There are no nerve paralyzing or hypnotic drugs in his body."

Xie Ji Bai didn't speak anymore, his mind was in a mess.Did Chang Lao really commit suicide?So before he died, he specially sent Xie Ji Bai a courier?

Xie Jibai felt that there must be something very important in that courier.

When Xie Jibai and Tang Xin arrived, it was an old community, but it seemed to be well taken care of.

They walked in, Tang Xin came here for the first time, and was a little curious about what the place Xie Jibai lived in was like.

Xie Jibai led him upstairs, then took the elevator, and soon reached the ninth floor.

There were only two households on the first floor, Xie Jibai knocked on the door of the one on the left, while Tang Xin looked at the anti-theft door of the one on the right.

Xie Jibai lived there before, but now it is impossible for him to go in and have a look, and he feels a bit regretful.

Tang Xin has never seen Xie Ji Bai when he was a child, and he has never seen a single photo.Xie Jibai resisted recalling the past, and would not put photos at home, so as not to bring back memories.

Soon the door opened, and there was a woman who looked older, but she was well-dressed and looked energetic. It was Chen Wanting's mother.

When Chen Wanting's mother saw that it was Xie Jibai, she immediately smiled and said, "Xiaobai, why are you here? Come in, come in, I haven't seen you for a long time, Wanting said that you are too busy with work, alas, you should pay attention to your body when you are so busy." , We always want to call you, just because we are afraid of disturbing your work."

Chen Wanting's mother was very enthusiastic, and she was also very happy to see Xie Ji Bai.

Xie Jibai smiled and said, "Auntie, I won't go in. I heard that a courier was delivered to me, so I rushed to get it. I'm still working overtime today, so I have to go back quickly."

"Oh yes." Mother Chen said quickly, "Then you wait, just leave it in the living room, and I'll get it for you right away. It was delivered this morning, and there is no sender. I don't know who sent it." You have moved here for many years, why are there still people sending couriers here. Fortunately, I am at home, and it is a coincidence that I heard the sound and came out to take a look. "

While talking, Mother Chen brought a courier package and handed it to Xie Jibai without opening it.

"Thank you, Auntie." Xie Ji Bai quickly took it.

Tang Xin stood beside him the whole time, and Chen's mother gave him a curious look.

Tang Xin smiled and said, "Hello, Auntie, I'm Xiaobai's...colleague."

"Hello, hello." Mother Chen greeted warmly and said, "Come over with Xiaobai when you have time."

"Okay, thank you." Tang Xin said.

Chen's mother obviously had a good first impression of the polite Tang Xin.

After Xie Jibai got the things, he went downstairs with Tang Xin, and when they returned to the car, they couldn't wait to open the package.

A cardboard box about forty centimeters in size, a little deflated.There is something rattling inside, and there is a sound when it is shaken, and it is not full.

Xie Jibai opened the cardboard box, and there were many transparent adhesive strips wrapped around the cardboard box, as if he was afraid that the express package would not be tight.

The carton was opened, Xie Jibai and Tang Xin had already eaten, there was only one thing inside, Chang Lao's notebook.

That day they went to the library and met Chang Lao. Chang Lao also had a notebook that was almost identical to Xie Jibai's, except that the color of the cover was different. This one was dark red.

Now, Chang Lao's notebook is lying in a cardboard box, and there is nothing else.

The notebook is worn and almost full of records, a thick one.

Chang Lao said that these are the library commemorative notebooks, and there are only eight of them.

Xie Jibai picked up the notebook and opened it. Sure enough, it was full of records, and there were not a few blank pages left.

With a "click", something fell out of the notebook.

Xie Jibai picked it up and found that it was a photo, probably from many years ago, and the photo paper was a bit yellowish.

This seems to be a group photo. There are many people in the photo. Everyone is standing together, covering them. It seems that the photo is not very clear.

Each person in the photo, holding a notebook in his hand, has a different primary color.

Xie Jibai and Tang Xin saw Chang Lao holding a dark red notebook at a glance.

At that time, Chang Lao's hair was not yet gray, and he looked quite young and energetic. If he hadn't held the dark red notebook in his hand, I'm afraid they wouldn't have recognized it at a glance.

There was another person with a brown notebook in his hand, that person was also very young, standing beside Chang Lao, it should be Peng Xuebo.

"Only seven people?" Xie Ji Bai counted carefully and couldn't help frowning.

Tang Xin said: "You forgot, there is also a person who takes pictures."

There are seven people in the photo, all holding notebooks from the library, one is missing.The one left was probably the one who took their picture.He hides behind the camera, completely missing his face.

The library is a private library, established many years ago by a few like-minded young people.In the beginning, there was only a small room of more than ten square meters.Later, they slowly built the library bigger and bigger.

They didn't want to build a big library at first, but just a private meeting place.These eight people are all highly educated, including psychologists, physicists, chemists, and so on.Chang Lao's main research direction is physical chemistry.

Although they have different design directions, they feel that they have a common language when they talk together, so they set up a library where everyone can exchange research.

They have a lot of strange ideas, sometimes very useless, sometimes very dangerous, but most of the time they can't study it in depth, after all, they need money as support.

They designed a logo icon for their library, with three lines forming a wing shape, implying their bright future.But sometimes, everyone will joke that the icon is more like a chicken paw.

After a few years, someone suddenly found them and was willing to fund their research projects. That person brought a very, very huge amount of money, and helped them run the library, which became what it is now.

But who this person is, they don't know, and no one has seen it.

But that was enough to change everything.

Chang Lao recorded in his notebook that from that day on, everything about them changed, because their crazy ideas had one day come true.

So many things happened after that, until one day, it finally reached the point of no return.

The library was broken, and because they didn't agree, a lot of people left.

Later, even police detectives stepped in and began investigating the case.Chang Lao wrote that things were more terrifying than he had imagined, and that person was no longer the partner they knew.

And the person Chang Lao mentioned was one of the eight people. He was holding a gray notebook in his hand, and he was the one who took pictures of everyone behind the camera.

He specializes in psychology and is very talented, but sometimes his thinking is too extreme, and others don't know what he is thinking. He often proposes some weird research directions, and the funder seems to appreciate him very much.

However, he almost died in an accidental car accident. Although he saved his life, he suffered from a strange disease called short-term memory loss.
