I'm trapped in a cube

"The last one..."

When he put the last book back, he found that the surroundings were eerily quiet.

"Is the transformation over?" He turned to look outside the door, only to find that the door that was there had disappeared without a trace, and was replaced by a densely packed bookshelf.

He rubbed his eyes and turned his head back, only to realize that the suitcase he had just been placing was actually a bookshelf filled with books.

He was sitting on the wooden floor, and the sound of metal friction and squeezing was no longer heard around him.

"this……"

This sudden change made him completely confused. He stood up in confusion, only to find that he had unknowingly arrived in a huge library, surrounded by bookshelves that could not see the top. In the center of the library were placed A reading table, covered in dust.

"Where is this?"

He walked around the library several times in confusion, but couldn't find the exit.

"Can't get out..."

He thought he would be safe after escaping from room 0122, but now he came to this strange library. He didn't know what happened for a while, and sat at the reading table for a long time.

The bright lights in the library shone on his body, and he noticed that his body had turned into a black shadow.

"When did it change?"

He recalled his previous experience and thought quickly.

"While I'm reading?"

It seemed that while reading the book "Cong Ying", his body became like this. Therefore, after waking up from the book, he did not feel any hunger or thirst.

The lights in the living area were too dim, and he had never noticed it before.

"What happened?"

The experiences during this period were completely beyond his cognition, and his thoughts became chaotic. The fantasies that appeared while reading and the current situation made it difficult for him to distinguish reality from fiction.

Martial arts novels, old-timers, a body like a shadow... what happened was too magical. His brain was completely shut down at this time, and he didn't know what to do.

In this way, he sat at the table for a long time. The lights in the library were always on and it was quiet. The huge bookshelf seemed to stand there forever. The densely packed books concealed countless mysteries, waiting to be explored.

He thought of the ever-changing "Shadow Sword Technique" again, and countless figures overlapped with him.

He turned into an old man for a while, the strange doctor for a while, his superior for a while, and a vague black shadow for a while.

"Who am I?"

A vague memory came to mind. He seemed to be in room 0123, flipping through the books on the bookshelf. His hands were already covered with wrinkles, and he looked like an old man.

In the blink of an eye, he arrived at the center of the fortress again, and issued an order to his former self to go to Residential Area Zero and persuade the people there to move out as soon as possible.

The people in Residential Area Zero suddenly turned into flickering shadows, sometimes appearing and sometimes disappearing. The pipes were squeezed, and the sparks from metal friction ignited a burst of fire. The flames rose higher and higher until they turned into a wall of fire that towered into the sky. .

The wall of fire wrapped around him and burned him to a crisp, but his body kept recovering. The pain and itching of his flesh and blood caused by healing kept tormenting him, and he could only keep running away...

"The patrol was wiped out, but why is he still alive?"

"The function of the relic...and besides, he is not human."

"What is he?"

"Shadow, he just pretended to be human..."

"What does he want to do? Does he want to replace us?"

"No, he himself doesn't know what he wants to do. He just imitates others. After learning one thing, he goes to learn another. He keeps imitating others. How can he know who he is? Even if he knows, he will forget it quickly. Born from shadows, there is no good end..."

A vague sound reached his ears, and he didn't know whether it was his own memory or the sound transformed from the words in the book "Cong Ying".

I couldn't tell who the voice belonged to. It sounded like an old man chanting beside him, or like a few strangers...

"Alas... Who is it? Is it so important?"

…

He woke up from his reading table in a daze.

It turned out that he had fallen asleep on the table because he was too tired.

The things I just dreamed about became blurry.

True or false, I completely forgot all about it, I only remember having a dream.

That's how dreams are, you don't remember what you should remember, but you remember clearly what you shouldn't remember.

He shook his head and slowly accepted the current situation.

"At least... you're alive, right?"

Although the library is closed and the body has become this weird, it will not die after all.

The worst thing is, stay in this library until someone comes to save you...

…

However, I don’t know how many years have passed since this time.

The books on the bookshelf were read one after another.

He also gradually got used to his body.

He wiped the reading table clean and picked a few books to read in his spare time. It was a very relaxed life, but his concept of time became increasingly blurred.

The library always looks the same. There is no change of sun and moon, and he has no way of keeping time.

Just like this, year after year, day after day, until Mo Ling arrives...

"I am familiar with everything in the library. Although the light of the mirror is very obscure, I noticed it immediately after it shone on me..."

"Can you tell me now? What are you? Are you sent by humans to save me?"

The black shadow asked Mo Ling anxiously, as if he had grabbed a life-saving straw.

But this is understandable. He has been lonely for too long and has been trapped in this unchanging library for so long. He finally met a "kind" who can communicate in human language. He must be very anxious.

But Mo Ling was still on guard. He thought about it and wrote a few words on the electronic screen:

"I am from the Pipeline Fortress."

"I came to you because I saw the prompt message you wrote on the donated relics, but I don't know how to get out now."

"Can you tell me where this is?"

In order to dispel the black shadow's suspicion, Mo Ling temporarily hid his identity and took this opportunity to ask the black shadow.

The black shadow once again caught the electronic screen that was transmitted in front of him and carefully read the content on it.

He didn't have much doubt. After thinking for a moment, he began to explain:

"This is still a pipeline fortress, but it is a pipeline fortress outside of perception. The library is a kind of concrete aggregate of knowledge."

"Take the pipeline fortress as the remains of the shell, and the library is like the remaining soul of the creature, which is full of the knowledge collected by the dead creature."

"But the structure of knowledge is very complex. The library is just an entrance. Through this entrance, you can enter deeper knowledge, that is, every book. These interrelated books will spontaneously materialize into a world for loading knowledge."

"Now we are in the world of Tianjin Mountain. The creatures, plants, natural environment, physical laws, etc. here are all the materialization of a certain book. They are combined into one here, balanced with each other, and combined into a "world" that can operate independently."

At this point, the black shadow suddenly changed the subject and pointed to the vines in the red mist.

"But, that thing is not..."
