Just when a few people were hiding behind the wall to peek at Director Jinchuan, a dark figure stood there in a place where they couldn't see, quietly watching their every move.

"Those police officers are idiots too," Director Tsukawa looked at the things in his hands and let out bursts of creepy laughter. "They must have never imagined that Tamada is sleeping quietly in this library!"

"Huh?" Curator Jinchuan suddenly counted the things in his hand in confusion, "Why is there one book missing?"

"Click!"

"Who!" Director Jinchuan suddenly turned around and stared at the glass door behind him. He walked over quickly, but there was no one there.

"Huh." Director Jinchuan snorted, slowly walked to the other side of the corridor, and stopped in front of a toilet cubicle door.

"Come out!" Director Jinchuan pushed open the door of the toilet cubicle.

"..." Looking at the empty toilet, Director Jinchuan exhaled, coughed slightly, turned and left.

"..." Behind the door, Conan and the other four people huddled together. They were so stiff that they didn't dare to express their anger. The cold sweat on their backs had already soaked their clothes...

"We... are still... for the time being." Conan twitched the corner of his mouth.

"...Don't go out to be safer..."

The night is getting deeper.

"I'm so hungry!" Yuantai said dissatisfiedly, hiding behind the door of the elevator compartment.

"Shh!" Conan covered Yuantai's mouth, "Don't talk!"

The bodies of Ayumen, Tai Mitsuhiko and others returned to stiffness in an instant, and the look of panic that had just faded appeared again.

In the distance, a crow chirped lowly in the dark night.

Conan frowned and looked at the suddenly dimmed lights in the library, "It looks like he's leaving." Conan murmured to himself.

Sure enough, after a while, the figure of Director Jinchuan slowly emerged in the darkness, his gloomy face expressionless, still holding a large box. He pressed the elevator button, walked into the elevator and went downstairs.

Conan jumped up, "Now, start the investigation!" He turned his head and said to the three people behind him.

"Yeah!" The children's nature made them instantly forget the fear of being trapped in the darkness.

"Then, let's go to the children's reading area first!" Conan took the lead, and the trio nodded and followed closely.

Children's Reading Room.

"Yuta, Ayumi," Conan pushed open the glass door that Ayumi had just touched and made a sound, "What you have to do now is to move all the books on the bookshelf!"

"Okay!" by Ayumi and Yuanta

"Okay, let's add..." Conan just turned his head and said to Mitsuhiko, when suddenly his eyes lit up, and the whole room suddenly became bright.

"Idiot!" Conan was shocked, "Why turn on the light!!"

"But..." Ayumi turned around slightly aggrieved, "It's so dark here, you can't see anything without turning on the lights!"

"What if the curator finds out?!" Conan said sharply.

"Ah!" Yuantai was so frightened that he clicked the button, and suddenly the room became dark again.

"..."

Conan resisted the urge to hit someone and glared at Yuantai. Yuantai also realized his mistake and shrank his neck guiltily.

Conan quickly walked to the window, looked at the deserted street, and breathed a sigh of relief. "It seems like he has really left."

In an unknown corner, there is a pair of eyes looking at the light that was instantly extinguished after regaining sight, with an eerie light shining in the pupils.

Half a ring.

"I'm exhausted." Mitsuhiko sat down on a thick pile of books and looked at Conan while panting.

"However, we finally moved all the books on our brand." Conan wiped the sweat from his forehead and shook his bangs.

"But Genta and the others are really slow!" Mitsuhiko said dissatisfiedly as he looked at the layers of books on the opposite side of his bookshelf.

"Maybe it's because Ayumi is a girl!" Conan said and walked to the other side of the bookshelf.

As soon as Conan walked out of the bookshelf, he heard Genta's dissatisfied shout. "Conan! Mitsuhiko! What are you doing! Quickly move the books over there!"

"...?" Conan heard this inexplicably, "You obviously didn't move down there, right?" When Conan quickly walked to the other side, he was shocked to see Ayumi and Yuan Taizheng sitting in a pile, panting.

In the book.

"This?!" Conan's eyes suddenly widened, "How is this possible?!"

No, Conan looked at a large pile of books and looked at the number of books that Yuanta moved out. Judging from the number of books that Yuanta moved out, they did move out all the books on the bookshelf, and it is even more impossible for us to put it this way!

"Come here!" Conan jumped down from the pile of books and pulled out a book on the other side.

"Sure enough." As Yuantai and others gathered around, Conan looked at the gap on the other side, "Another row of books was stuffed between the two rows of books." The book in Conan's hand was the English book that Qian Yu had pulled out during the day.

Original book.

"Conan!" Yuantai pointed at the books in Conan's hand and said with a hint of horror, "These books don't have back covers!"

"There's no back cover?" Conan was surprised and looked down.

"That's it!" A bright light flashed in Conan's eyes, "No wonder, Yuantai and I both saw that there was a book on the opposite side that had not been put down. It turned out to be something without a back cover! Ha!" A strange color flashed in Conan's eyes.

.

"Seal it inside upside down..." Conan pondered for a while, then suddenly tore open the packaging bag of the book, and then broke it hard.

This kind of thing cannot be a book at all! Conan thought, the original items imported from abroad are either pistols or...

"Drugs!"

Looking at the packet of white powder in his hand, Conan took a slight sniff and frowned.

"It's really..." Yuantai and others immediately opened the "books" in their hands, and sure enough, they were all wrapped in bags of white powder.

I see. It seems that Mr. Tamada was the one who discovered Director Tsugawa’s behavior and was silenced by him. Conan held his chin and looked at the thing in his hand in concentration.

"Hey, Conan!" Mitsuhiko's voice interrupted Conan's train of thought, "Look at the bookshelf over there!"

"Huh?" Conan looked up and saw the three rows of strange bookshelves at a glance.

These three rows of bookshelves are tightly attached to the wall, each with a rotating handle connected to a bearing.

"Could it be that?!" Conan was startled, jumped up to the top of the bookshelf, and pulled the handle hard.

With a clicking sound, dust flew down and the two bookshelves suddenly separated.

"Eh..." Conan looked at the empty bookshelf in shock, "Empty?"

Ayumi and Mitsuhiko also worked together to open a bookshelf, but still found nothing.

"Conan!" Suddenly Genta's voice came, sounding very laborious, and Conan quickly raised his head.
