There were many ordinary guests in the library who heard the news, and there were even people who tried to break open the wooden box with brute force like the uncle, and in the end, they all had their fingers stabbed in the end.

It seems to be the idea of the owner of the box, and except for those Kidd fanatics, ordinary people can come in and visit.

"As you can see," Jiroyoshi explained, "the box is placed directly on the table, there are no special guards, and anyone is free to touch it as long as they are in this library." ”

"And what if someone escapes with the box?" Xiaolan wondered.

"Don't worry, just turn on the mechanism and the weight sensor buried in the floor under the table will activate," Jirangyoshi demonstrated, "even if the weight that comes in is only a gram lighter than when it goes out......

Bang dang!

Jiro Yoshichi stepped out of the floor and was enveloped by the iron cage falling from above, and it took him to press the button again to make the iron cage rise.

It looks like a bluff, but it's an old trick, and I've never managed to catch Kidd before......

Gao Cheng was thinking crankily in the back.

What happens if someone farts when they leave?

"Haha," said the old man Jiroyoshi proudly, "how's that?" Even if there is a way to escape from this iron cage, you can't escape the library, all the entrances here are equipped with iron gates, which will be triggered along with the iron cage.

Even if Kidd secretly opens the box and takes the gems, he will soon be found! ”

"There is no way to open this box secretly," the old lady shook her head, "when you open the box, the music box inside will automatically play the melody, I heard the sound of the music box in the middle of the night several times, and then I found out that it was my husband who opened the box in the study......"

Xiaolan asked curiously, "What kind of melody is it?" ”

"This," sighed the old lady, "it has been more than ten years since my husband last opened this box, and I don't remember, it seems to be a very famous nursery rhyme. ”

Conan looked at the wooden box and thought about it, and whispered to Gao Cheng: "Let's not talk about the others, it seems that I want to open this box no matter what, even with the help of the ability of the monster thief Kidd...... Do you think that guy has already infiltrated it? After all, the security is so lax, there is no reason why that guy should not step on it. ”

"it."

Gao Cheng's eyes widened and he looked at the trap box.

He doesn't care what Kidd does, unlike Conan, he doesn't have the feeling of a rivalry at all, and he only has a few labels in his head: "tool man" and "fat sheep".

There's no way, I know Kidd's true identity from the beginning, there's no mystery at all, that guy is a funny women's clothing boss.

And then......

Gao Cheng's afterglow swept over Xiaolan.

I don't really care about it, but it's impossible to turn a blind eye.

He felt it from just now, Xiaolan in front of him was not the right height, if nothing else, it was Kidd's guy.

Unlike his camouflage card, no matter how superb his camouflage ability is, it is impossible to be absolutely perfect, although Kidd is a top-notch woman in clothing, but this time Xiaolan did not wear high heels, and her clothes were relatively thin, no matter how hard she tried, her height could not match.

Obviously, there are so many people who can be disguised, this guy actually chose Xiaolan, is it floating?

"Didn't you say there was a piece of paper with the method of opening the trap box?" Gao Cheng turned to the old lady and asked, "In this case, it should be possible to open it according to the instructions, right?" ”

"Yes, yes, but I don't know where."

The old lady said quietly.

"In the middle of the night, after my husband closed the box, he sandwiched a diagram of the box with arrows and numbers in a book.

Two days later, I went to the study to look for the paper, and wanted to know which book it was with, but when my husband saw it, he said that I couldn't find it, and I really haven't found it until now. ”

"What about the books?" Uncle Maori asked.

He's not so hard to find......

"It's all given to me," Old man Jiroyoshi led the group into a separate library next to it, "I'll leave them all here." ”

The library is not large, but it is surrounded by towering bookshelves full of books, and the highest part requires two scaffolding indoors to get it, which is comparable to the Kudo family's study.

"Are they all these?"

The group was completely stunned.

"At a cursory glance, there must be about 10,000 books, right? When was it found like this? ”

"Mr. Mori," Jiroyoshi asked, turning back to his uncle, "how do you think it's better to start looking?" ”

"I have no choice but to find ...... one by one"

"I mobilized all my staff and searched here for a whole day, but I couldn't find the piece of paper."

"Ugh."

The uncle froze, feeling a little faceless, but the words came out of his mouth, and there was no better way.

"Of course, after all, there are tens of thousands of books, and it is impossible to turn every page, so I can quickly turn through them," Jiroyoshi said in a deep voice, "but if you have a piece of paper in the book, you should be able to see that page at once when you turn the book." ”

"Well," the uncle felt a little difficult, "that's true...... Could it be that they were hidden somewhere else after that? ”

"No," denied the old lady, "my husband died in a traffic accident the other day, and he could not have foreseen this.

And, every time I came back from the house, he would say, 'It looks like that box hasn't been opened yet, because the paper is still in the old place...... Is it really too hard for you? But if you really want to read it, I can tell you which book that paper is in it......

He said so, but it was so unwilling, as if I could never find it, so I didn't ask him, and kept trying to find out for myself. ”

Gao Cheng half-collapsed eyelids.

This old couple really has a set.

"It's strange, if it's really moonstone in the box, is it necessary for your husband to hide it like this for fear that you will find it?"

"My husband is shy, maybe there is a ...... in it"

"And?"

"I—I don't know, that's why I want to open it and take a look." The old lady said.

Gao Cheng didn't ask, anyway, it was probably the couple's personal belongings.

The important thing now is to find the instruction manual of the trap box among the tens of thousands of books in this library, anyway, it is impossible for him to crack the trap box, and the entry-level trap is too far behind.

The key clue is that the old lady can't find ......

"I said," said Uncle Maori, who rushed forward to the old lady, "that piece of paper must be tucked between those books that you don't usually read, Madame, right?" ”

"Probably," the old lady recalled, "books I don't read, reasoning that would kill people, and fantastical ...... of all sorts of terrible monsters."

Gao Cheng looked at the uncle from behind.

Well, reasoning and fantasy exclusion.

If the old lady did not know the secret of the explanatory paper, it was of course very likely that it would be sandwiched in these books, but it would not be possible after the old lady knew about it.

Since the old gentleman was sure that the old lady could not find it, it meant that the paper would be sandwiched in the book that the old lady would not find.

For books that I don't usually read, the old lady will look through them as soon as possible, after all, she is just looking for notes, and she doesn't need to read the contents.

The safest places are the most dangerous......

If you think about it this way, the old lady should be familiar with that book, but she won't look for it.

Uncle Maori and Conan went to the bathroom, and the few people who stayed in the library didn't have the idea of helping to find it, but looked at their favorite books.

Gao Cheng's gaze swept over "Xiaolan".

This guy is very self-aware, and he didn't accompany the garden to the toilet, but the appearance of looking for a book in this way is very eye-catching, that is, Conan is not there, otherwise he will see through it immediately.

Shaking his head, Gao Cheng continued to ask the old lady, "What book are you most familiar with?" ”

"The most familiar book?" The old lady was stunned, "I don't actually read much, but my husband did buy a lot of cookbooks for me, who likes to cook." ”

Old man Jiroji looked at Gao Cheng in surprise, and even "Xiaolan" stopped what he was doing.

"Is there anything wrong with the cookbook?"

"Tens of thousands of books are too many books and need to be narrowed down."

Gao Cheng held a bunch of cooking books and put them on the table, but he didn't flip through them immediately, just smiled and said.

"First of all, it can be determined that if you look through it, even if you read all the books, you can't find the instruction manual note in the folder, which means that the paper needs to be found page by page.

But if you can find it page by page, the old gentleman will not be so sure that the lady can't find it,

There is only one reason, and that is that the books that are hidden in the Madame are easy to ignore when she is rummaging, and the more familiar the book, the less Madame thinks that it will be the place where the old gentleman hides the note. ”

The old lady looked a little confused: "However, I usually read all these cookbooks word for word......

"Do you really read every page?" Gao Cheng asked rhetorically.

"This ......," the old lady hesitated.

Of course, some of the dishes that can be cooked will not be specially seen.

"Let's put it this way," Gao Cheng picked up a cookbook, "which of these cookbooks are some of the dishes that your husband was very good at before he hid the note, and you won't read it in the future?" ”

"Probably," thought the old lady, "my favorite dish is potato stew, and because he likes to eat it, my mother-in-law herself taught me how to make it." ”

"Let's look at the potato stew on the side."

Gao Cheng flipped through the cooking books one by one.

He didn't know exactly what he couldn't find at a cursory glance, but it wasn't impossible to do it.

It's just a little magic.

The principle is that if the edges of the paper are uneven, if the edges of several pages are cut off, when you turn the book with your fingers, the shortened pages will automatically turn over, forming a hidden effect.

This is a way to do this, or just glue two pages together.

"There it is, potato stew."

Old man Jiroyoshi was pleasantly surprised to hold a cookbook and unfold one of the pages, and sure enough, there was an instruction manual for the trap box.

"It's amazing, it's really here! Haha, it's still a good detective in the city! ”

"Smack!"

The lights in the room suddenly went out, and for a moment it fell into darkness.

"Huh? Blackout? ”

"It's Kidd, right?"

Conan and Uncle Maori just returned, and there was some confusion in the dark.

"What's going on? Have you found that manual? The uncle heard the old man Jiroji praising Gao Cheng outside, and his face was ugly, so he went to the bathroom, which was too much.

"Now is not the time to talk about this," old man Jiroyoshi yelled at his men, "Hey, what are you guys doing?" Hurry up and restore the lights! ”

In the dark hall of the library, a pleasant music box melody was heard to attract everyone's attention, and then there was the sound of the anti-theft iron cage falling.

Conan and Uncle hurriedly rushed back to the hall again, but Gao Cheng didn't follow, just turned on the watch flashlight, and sure enough, there was no trace of "Xiaolan".

He didn't think Kidd had actually opened the box.

Because the music box melody in the dark is obviously wrong, the tune is "The Old Bell" composed by the American Henry Walker in 1876, and it only came to Japan in 1940, and Misui Yoshiemon at the end of the shogunate never heard it at all.

Kidd doesn't seem to know enough about music.

What's more strange is why you chose to shoot at this time, obviously the machine box manual has just been found.

"I have taken the contents of the box...... Kidd the Thief! ”

The lighting in the hall was restored, and the uncles who rushed to the hall first exclaimed, and the old man Jiroyoshi was directly stunned.

"Did it take only so little time in the darkness to open the trap box of Misui Yoshiemon?"

"How is that possible?"

Gao Cheng looked at the Kidd card on the trap box and said speechlessly.

"That guy just can't afford to lose."

"Huh?"
