"There is no one on the first floor."

"There is no one on the second floor."

"There is no one on the third floor."

Drones rush to the front line, and special forces follow in real time, searching every room.

If there is a locked room, the key is used to unlock it.

The keys came from the library's administrators to prevent all the doors from being physically broken.

The special forces quickly cleared the door to the sixth floor, and no missing security guards were found on the five floors.

In the process of investigation, the technical investigators found that the library's surveillance video had been cleared and all surveillance video had been lost.

The four of Kemeng came to the door of the sixth floor with Tang Yuan, and felt an obvious strange feeling.

Among them, Kemeng is the most, Kemeng smells the smell that has dissipated, and if it is not for synaesthesia, it is difficult to smell the smell that has been retained.

The smell of printing paper in the air was still there, and it was a cover-up, but Kemon could smell it, it was the smell of rotten books, the smell of mold.

The musty smell was not ordinary, and Kemon took a step inside, feeling more and more intense.

Luo Yuan also stepped inside, and took out a paper talisman in his hand, which was one of his attack props.

When the special forces saw it, they immediately asked if they could enter, and Dr. Liang said: "Don't go on too many people, one person, just protect the investigators, too many people will destroy the synaesthesia conditions at the scene." ”

The cluttered scene is inconvenient for investigators to synaesthesia, and the fewer people the better.

Of course, sometimes it is not always better to have fewer people, depending on the situation.

After Kemon stepped inside, he looked around, his nose moving, looking for the musty spot.

Luo Yuan and Cheng Le also saw some stains through their glasses, and the route was exactly the direction Kemeng walked towards.

The rice balls rolled in the back, and the golden hair was extremely clean and out of place in the environment.

The special forces are holding submachine guns, and their nerves are tense all the time, and once there is a change, the first priority is to protect the lives of the investigators.

Fifteen steps later, Kemon stopped at a row of corners in the east corner, his gaze resting on the second empty space on the left on the third floor of the bookshelf.

Kemon had a gut feeling that there should have been a very moldy book in this empty space.

But where will the book go if it's gone?

"Can you call the curator, or call the administrator of the sixth floor, I need what books have been placed in this vacant space." Kemon pointed to the empty seat.

"Yes!" The special forces turned on the intercom button and told Kemon what he wanted.

"Understood, delivered in a minute." A calm male voice came over the intercom.

Kemon looked around, his brow furrowed, and walked along the library floor, taking in the strange sensation of the room.

In addition to the smell, there is also a strange feeling.

I couldn't tell what it was, as if something was holding Kemon back from perceiving.

What's missing?

A flash of light flashed, and Kemon remembered.

It's a figure by the window!

Kemon once looked up from the sixth floor downstairs and saw a black skinless figure looking down against the window.

Why did you enter the sixth floor but no human synaesthesia appeared, this is unreasonable.

Kemeng told the captain the question in his heart, Luo Yuan frowned, and thought quickly: "The door here has been blasted, destroying the best synaesthesia environment, so some information can't be obtained." ”

Kemon stood at the unclosed window, looking down through the window, and saw a group of soldiers.

What was the figure looking at?

Kemon frowned, unable to figure it out.

At this time, the administrator and the curator of the sixth floor both entered the sixth floor, they were both old, and it was the special forces who carried the two of them upstairs all the way, otherwise they would not have arrived in a minute.

"Report, the man has arrived!"

"Hello comrade, I'm Jin Qiwen, where did you say that vacant seat is, I'll take a look." The old curator wiped the sweat from his head, a little anxious.

When the director first learned of the accident in the library, he rushed over, but he couldn't get in, and it wasn't until half a minute ago that someone told the non-commissioned officer that he needed to go upstairs to cooperate with the investigation.

"Hello, hello, I'm Chang Chengwen, the administrator of this layer." Another fifty-year-old apologized.

Luo Yuan shook hands and led the two to the bookshelf in the east corner.

The curator frowned, looking like he was meditating, obviously he was old, and he hadn't been to the sixth floor for a long time, so he had forgotten a little.

But the current administrator still remembers what books are placed here, and besides, even if he forgets that he has a paper record, don't panic.

"I remember that the book placed here is "Whale County Travel News", which is an old book published 80 years ago, and the collection of books is recorded here." The administrator found the catalogue and pointed out that the book in the empty shelf was "Whale County Travel News".

Kemon looked at the catalogue file and matched it with the bookshelf, but the book was not here.

"Do you need us to look them all?" The soldier leading the team asked in a low voice.

"Let's look for it first, and besides, we need to install a new door, preferably to restore the original environmental scene." Luo Yuan said.

"Yes!"

The special forces turned on the walkie-talkie and said the request.

The walkie-talkie paused for only three seconds, and immediately replied, "Give us half an hour." ”

The official forces are operating behind the scenes, and an order goes down, and immediately finds a factory that makes steel doors to quickly customize them, copy them according to the original style, and then transport them by helicopter to ensure that they are fast.

The debris from the site was cleaned up piece by piece, and the fallen books were put back in their place.

Synaesthesia requires a good environment.

There is some hidden information that is too subtle to know what happened before without the original environment.

Now the investigators are waiting for the environment to be restored, and then the four investigators will have synaesthesia to capture that feeling.

Half an hour later, the helicopter came, bringing in half of the steel doors and professional installers.

The blast only blows open half of the door, as long as the other half of the door is installed, it will not have much impact.

Installers quickly went upstairs to install the steel doors.

The steel door was originally brand new, but the Investigation Bureau sent an investigator to bring a special item for the old treatment, which can make the door age to a certain extent and adapt to the original door.

The investigator held a magnifying glass and examined the door.

The area that is viewed by the magnifying glass will show a certain amount of aging.

The longer you look at it, the more aging you age.

As for the side effects...... The investigator put down the magnifying glass, his eyes were tearing, tears were pouring and flowing, and the time of tears was equal to the time of fixation.

100% restoration can't be done, at least with the existing technology, like seventy or eighty percent is already very powerful, you must know that it is only half an hour, which also includes the time to rush.

After a while, the soldiers closed the door, leaving the four investigators alone in the sixth floor secret room, and the rice balls were put into a scarf, because its image did not fit in with the environment, so that Luo Yuan and Cheng Le could not concentrate on synesthesia, and they were always interrupted.

After closing the door, the light dimmed by four minutes, and the room became a little drowsy.

The curtain was only open on one side, and the light was severely insufficient, making the place where the light could not shine slightly darker, as if something was standing there.

Kemon cleared his mind and felt the truth that might be hidden in the sixth layer.

He stood at the place where the musty smell was the most strong, and walked slowly in the direction of the musty smell.

After a dozen steps, Kemon stopped in front of the window where the curtains had been opened.

Leaning down to look below, a group of people.

No, it's not about people.

Kemon shook his head, and then thought of something, his right hand was clenched, and his thumb and four fingers were left in gap, just enough to hold a book.

It was this small detail that gave me a strange feeling in my heart.

Someone once took "Whale County Travel News", stood in front of the window and looked down, he was completely black, with the appearance of a person, but no human skin, and a black background behind him.
