Although there were no warning signs on the inside of the wardrobe, the innermost cabinet against the wall felt significantly thinner than the others.
Generally speaking, in order to save materials, the wood used for the innermost cabinets is very thin.
That makes sense.
Qin Yuanyao tapped the cabinet again with her fingers.
When you knock on the innermost cabinet, the sound is much hollower than when you knock on the other cabinets, which sound deeper and more solid.
Qin Yuanyao was puzzled when she suddenly heard Chi Baiyi's voice.
"Come and take a look, is this the area the girl is pointing in with her left hand?"
Qin Yuanyao and Chi Naozhi didn't find any useful clues in the cabinet, but when they heard Chi Baiyi say that, their attention was drawn to it.
Qin Yuanyao went to Chi Baiyi's side and used her eyes to measure the direction the girl's left hand was pointing; it was indeed towards the bookshelf.
"Is she pointing to a book?" Qin Yuanyao asked, puzzled.
Using the same method, she traced an empty straight line with her finger in the direction the girl's left hand was pointing.
Finally, her finger, which was drawing a straight line, touched the book "Admonitions for Women".
Qin Yuanyao looked surprised and confused. "Is she referring to this book?"
Chi Baiyi's gaze deepened. "Let's take a look first."
The book was brand new, with no markings or signs that it had been seen by anyone else.
Qin Yuanyao flipped through the book from beginning to end but found no clues whatsoever.
“There are no clues.” Qin Yuanyao said to Chi Baiyi, “Could she be referring to other books?”
"Let's look at all the books nearby," Chi Baiyi said.
Qin Yuanyao and Chi Baiyi took out all the books around "Admonitions for Women" and flipped through them.
Chi Cheese helped them flip it over.
They read through nine or ten books from beginning to end, but still found no clues.
"Could she be referring to the bookshelves behind?" Qin Yuanyao wondered again.
“We’ve already searched through both bookshelves, but we haven’t found any clues,” Chi Baiyi said.
"Is it possible that we didn't look at it carefully enough and missed something?" Qin Yuanyao asked.
Since the girl's finger was pointing in this direction, it must have a purpose.
Qin Yuanyao could only think that perhaps they hadn't searched carefully enough and missed something, which was why they hadn't found any clues.
Chi Baiyi understood what Qin Yuanyao was thinking.
He nodded. "Let's flip through it again."
They first searched through the books on the back shelf in the direction the girl pointed, but found nothing, so they expanded their search area.
By the end, they had basically gone through all the books on both bookshelves again.
[This is too difficult! It's too difficult! Seeing Yao Yao and the others flipping through so many books from beginning to end makes me feel like it's so hard!]
Are the clues really in these books? Could they have looked in the wrong place?
Sigh, who knows? Until the password is cracked, no place can be overlooked; there might be clues anywhere.
I noticed the other four groups of guests weren't having much luck either.
[The production team must have pulled out all the stops this time. They probably don't want them to come out easily and are deliberately delaying them.]
“No clues…” Qin Yuanyao sat down on the bench, feeling a little tired.
Chi Nai nodded her fluffy little head, her face serious. "Yes, it's so difficult!"
Chi Baiyi re-examined the painting and the calendar.
“The drawing and the calendar should be clues, especially those four strings of numbers…” Chi Baiyi pondered, “What could be the connection between the direction the girl is pointing, the calendar, and the numbers?”
Qin Yuanyao also looked at the painting and the calendar.
The girl pointed to the wardrobe with one hand, which was empty. She pointed to the bookshelf with the other, which contained the books… What could those four strings of numbers have to do with the books?
Chi Baiyi continued, "The four strings of numbers have the same structure, and the first four numbers are also the same. Is there some kind of pattern?"
Chi Nai's soft little hands supported her cheeks, her face full of worry.
She asked in a grown-up manner, "Is there any pattern?"
All three of them fell silent.
Chi Nao felt that if her parents couldn't figure it out, then she, a little kid, would be even less likely to be able to.
She was tired from resting her chin on her hand, so she put it down and was about to sit up straight when her gaze swept over the books on the table.
There is a book with its back facing up.
Chi Nia's gaze swept over the string of numbers in the bottom right corner of the book, and she froze.
She stared at the string of numbers several times, then slid off the chair, ran to the calendar, and silently compared the four strings of numbers on it in her mind.
After comparing them, Chi Nao exclaimed happily, "Sister Qin! Dad! These four strings of numbers look just like the numbers on the back of the book!"
Qin Yuanyao and Chi Baiyi were both taken aback.
They grabbed the nearest book and turned to the back.
Sure enough, there was a string of numbers in the bottom right corner of the book.
Qin Yuanyao compared the numbers on the back of the book with the four strings of numbers on the calendar and immediately understood.
"Book number! The numbers in front are the book number!"
【Huh?? What's the ISBN??】
When this book editor saw those four strings of numbers, they looked strangely familiar (facepalm). They really were ISBNs! (facepalm)
[For those who read this, a book number is a unique identifier assigned to each publishing house by the General Administration of Press and Publication. It's essential for publishing a book; without it, you can't set a price and sell it. The book number is usually on the back of the book—it's a string of numbers and a barcode.]
I picked up a book at random and looked at it; it really did have an ISBN!
[If you weren't in the publishing industry, you'd never guess it was an ISBN. Cheese is amazing!]
[Yes, even though I love buying books, I don't specifically look at the ISBN. Cheese's observation skills are truly amazing!]
“978-7-3356-1345-3, these are all book numbers up to this point, and we don’t know what the numbers after that are,” Qin Yuanyao said.
With Chi Cheese's prompting, Chi Baiyi had already realized that the numbers in front of them were book numbers.
"Let's find the four books that correspond to the book numbers first."
"Okay!" Qin Yuanyao and Chi Naoqi both responded.
They divided the work and quickly found the books corresponding to the four book numbers.
"But what are the numbers after the book number?" Chi Nao asked cutely, tilting her head.
Chi Baiyi and Qin Yuanyao were both lost in thought, neither of them speaking.
[Keep it up! You've guessed the book number and found the book, you must be very close to the answer!]
[The numbers that follow should be related to the corresponding books, right?]
I think there's probably a connection; otherwise, why would they go through all that trouble guessing the book number?
The other groups are still completely clueless, only Teacher Feng's family is slightly ahead, and they seem to be getting closer and closer to the code. Yao Yao's group, on the other hand, is almost seeing the light at the end of the tunnel!
Chi Baiyi's eyes flashed, and an idea suddenly came to her.
