Together with the Matt student named Pisa, Su Qingxing left the study room and walked into the hall, and then found that the students who had been reading and studying on the first floor of the library had really disappeared without a trace.

Apart from Su Qingxing, the whole library does not seem to have any breath of living people anymore. the whole library has suddenly become a deserted and empty city. the originally comfortable air-conditioning air-conditioning is also a bit chilly at the moment.

"We have to go back to where we started." Su Qingxing actually hated the teaching building he had been to before, but when the three people walked out of the library and faced the same thick fog around them, Su Qingxing found the gloomy teaching building with a weird mirror even more sense of security.

"I'll call my brother!" Bai Hua remembered that Su Qingxing seemed to be on the phone with the owner of the bookstore, so now she took out her cell phone and dialed the number of the teacher Bai without saying a word.

"Hello? Birch, where are you now? The teacher said that you and Su Qingxing were already late for half the class. "

Half a class?

The birch who connected to the phone did not think too much, but immediately asked for help with a moved face and said, "Brother!" We are still in the library, but I don't know why we can't find a way out! There was fog all around, and even the tree-lined path disappeared! "

"what are you talking about?" The teacher Bai on the other end of the phone didn't seem to understand what his brother said, and the phone in Betula's hand immediately set up a hands-free function, so that people around him could hear what the teacher Bai said.

"are you in the library now? How is that possible? " The incredible tone of Mr. Bai came from the other end of the phone. "hasn't the school library been renovated since Saturday?" Now that even the gate is blocked, how do you get in? "

Su Qingxing and the three of them looked at each other in surprise.

"how is that possible?!" Birch obviously didn't believe it. "there are so many in the library." People. " Bai Hua stopped in the middle of her words, because he knew very well that the people who were originally studying in the library had disappeared.

"to be late is to be late. Don't make any other excuses!" Mr. Bai seemed to think that his brother was lying, and then he said a lot of words, but the signal around the library seemed to be not good, and the intermittent shrill electric current on the phone made it impossible for them to hear what Mr. Bai said later.

"Brother, we are really trapped in front of the library! There is fog all around. Come and save us! " After birch shouted, a hang-up interface appeared on the phone screen.

When he tried to dial the phone again, there was a large busy tone, and no one came to get through to him for a long time.

"I seem to have heard of the renovation of the library. There seems to be such a notice on the bulletin board at the door." The smoky make-up killer Matt Pisa swallowed nervously, "but I don't usually come to this place, this time I just made an appointment to meet here, and then saw the door open and subconsciously came over!"

"if there is really a notice of renovation. If the door of the library is really blocked. So where on earth are we now? " Su Qingxing looked up at the four-story building in front of him, and the three golden characters of the "library" above were still reflected, but in Su Xingxing's eyes, the building, which was supposed to be full of books, seemed to have devoured the demon fortress of mankind.

With the help of the darker and darker sky and the lights at the door, the glass of the library gate looks like a black mirror reflecting the three of Su Qingxing.

Mirror?

"is there a mirror in the library?" Su Qingxing suddenly had a flash of inspiration, and some hurriedly asked, "any mirror will do!"

"I remember there was a mirror around the corner on the second floor." The birch frowned and recalled, "it looks like the one in the teaching building, but can the mirror take us out of this inexplicable place at such a time?"

"We can't get in touch with other people right now, can't we?" Su Qingxing's mobile phone has already appeared on the sign that there is no signal, so now the stand said, "maybe we can only use some special ways to find other 'people'."

If you can't get in touch with other people, and the original students in the library have become unknown, then Su Qingxing can think of it. It was the man in the mirror who had appeared in front of him several times, and the little girl holding the bear doll.

At this point, Su Qingxing was also a little confused about whether she was standing in the corner or in the decorative mirror behind the window when she first met the little girl.

But at least the person who looks no different from Mr. Bai did appear in the mirror several times.

Since they really can't find anyone else, they might as well try to find someone in the mirror!

Although they didn't know why Su Qingxing was looking for a mirror, the three men walked as fast as they could through the first floor of the library, where there was no one, and then came to the corner of the corridor on the second floor.

There is indeed a square mirror, the frame looks like old wood, and the signature given by the class of so-and-so is written in the lower right corner.

"Qingxing, can this mirror really help us find someone?" Even under such circumstances, Birch's expression seemed to think that Su Qingxing was going crazy.

"is this little brother a descendant of some metaphysical school?" Matt, a killer named Pisa, looked up and down at Su Qingxing. "my pizza likes talent best. If the little brother can find a way to get us out of here, then you will be the one covered by my pizza!"

"actually, I don't know if I can." Su Qingxing himself felt a little absurd. He was an ordinary student a few hours ago, but after a night that he didn't even know, it was as if he had come to a different dimensional space and encountered all kinds of things that seemed very strange.

After taking a deep breath, Su Qingxing pressed his right hand directly on the mirror.

A little closer to the mirror, the distance between Su Qingxing and the mirror soon became smaller, as if Su Qingxing was going to stick to the mirror the next second. But even so, Su Qingxing did not see anything other than the three of them in the mirror.

"what exactly are you looking for?"

Su Qingxing heard the confusion behind him, in fact, he did not know what he wanted to find in the mirror. If there was something else in the mirror, could they really escape from here?

Why did they walk into the blocked library?

Why is there fog all around?

Where on earth did the others go?

"is anyone in there?" Su Qingxing knew it was stupid, but he knocked on the mirror a few times.

Just when Su Qingxing thought his behavior was stupid, he saw a teddy bear flashing past on the edge of the mirror!

"I see it. Are you right in there?" Su Qingxing put his hands on the mirror and said, "tell us, is there any way to get out of here?"

"."

As soon as Su Qingxing's voice fell, a figure in a long white coat appeared there, which was not in line with the summer dress, but it was indeed the one that Mr. Bai had worn before.

"Su Qingxing, what on earth did you see?" It was as if the birch could not see the change in the mirror at all, and even took a step back because of what Su Qingxing said.

In Su Qingxing's eyes, the "white teacher" in the mirror held the little girl's hand and stood right in front of Su Qingxing. The "white teacher" said a lot of words, but because he spoke too fast or for other reasons, Su Qingxing could not tell what he was talking about, so he shook his head doubtfully.

"Mr. Bai" sighed, finally stretched out his finger and scratched an English word with his finger on the other side of the mirror.

Su Qingxing doesn't know.

Perhaps thinking of this key, Mr. Bai wiped it with the palm of his hand and wrote two words again on the mirror

All clear.

"safe?" Su Qingxing did not quite understand these two words, but teacher Bai wrote too many words with his fingers, and Su Qingxing failed to understand again.

Obviously Su Qingxing read the string of words very seriously, but I don't know if it was because of the opposite direction that Su Qingxing could not memorize a word at all.

"be careful outside." After writing it several times, Su Qingxing understood the four shortest words that Mr. Bai wrote later.

Watch out, okay?

Safe?

"you mean the fog outside is dangerous, so you want to stay in the library?" Su Qingxing tried to understand.

But the "white teacher" in the mirror still shook his head.

"Qingxing, who on earth are you talking to?" Standing at the back, birch and pizza are in a bit of a hurry. In their view, Su Qingxing was just talking to himself in the mirror, as if he had suddenly developed symptoms of schizophrenia.

"in the mirror." Su Qingxing was about to explain when he saw the "white teacher" in the mirror shaking his head.

After that, the "white teacher" suddenly pointed his finger at himself and tried to say two words with his lips.

DANGER.

Point to yourself and say dangerous?

Is it that the "white teacher" in the mirror is dangerous, or the white teacher outside the fog is dangerous?

Su Qingxing suddenly opened his eyes wide, as if thinking of something, and asked seriously, "do you mean that the place we are now is safe, but we will encounter danger after leaving the fog?"

"Mr. Bai" nodded.

"and the source of the danger is." Su Qingxing did not say the name, but the "white teacher" who looked at the mirror like this.

The "Mr. Bai", who tried to convey some messages, smiled with relief.

His message has been accepted by Su Qingxing, and if what the people in the mirror say is true, then the "white teacher" seems to hope that Su Qingxing can stay in the library, because what is really dangerous is the world outside the fog!

And that teacher Bai is also a dangerous person! Su Qingxing did not forget that when he was in the office, the man in the mirror once told himself not to eat, referring to the local products given to him by teacher Bai.

Such a message seems to be completely different from what Su Qingxing guessed just now.

Is the library safe?

It's dangerous out there?

"but I can't stay here." Su Qingxing finally shook his head with a twinkle in his eyes. On their way to the library, Su Qingxing received a message from his mother, who seemed to have begun to prepare lunch and asked him what he would like to eat.

Thinking of his mother Su Ye's smile, Su Qingxing still wants to leave here.

"I promise I won't go near the danger. Tell me how to get out of here."

After hearing Su Qingxing's questioning, a large and a small one in the mirror showed a helpless expression, and then disappeared from the mirror hand in hand.

At the moment when the man in the mirror disappeared, the sky outside the window seemed to brighten up a little.

"Su Ching Xing! White birch! Where are you? " At this moment, a familiar voice suddenly came from outside the library, and the appearance of that sound made the birch jump with delight, which wanted to knock Su Qingxing out.

"it's my brother! Brother came to find us! " The birch rushed downstairs and saw Mr. Bai who was rushing in through the door.
