Yu Dong also looked at Caitlin in surprise, suddenly smiled, and then waved to the staff next to him, "Go and get this lady a set of collector's edition books."

"Really?" Caitlin exclaimed in surprise, "Did you just give it to me?"

Yu Dong smiled and nodded, "Well, it belongs to you."

Soon, the staff delivered a set of collector's edition books.

Caitlin struggled to take the set of books and thanked Yu Dong repeatedly: "Thank you, YU, thank you very much."

In fact, Caitlin is still confused. She has no idea why YU gave her a set of collector's edition books. Is it because she asked for it?

This shouldn't be possible...

Hathaway also thought this was impossible, but when it was her turn, she couldn't help but cautiously said to Yu Dong, "YU, I want a set of collector's edition books."

After finishing speaking, Hathaway looked at Yu Dong expectantly, hoping that she could be as lucky as her cousin.

But the goddess of luck did not come. Yu Dong shook his head with a smile and said, "Sorry, this symbol is no longer valid."

Yu Dong's words aroused discussion among subsequent readers.

Judging from what this means, Caitlin was able to obtain a set of collector's edition books because she triggered a certain symbol, but this symbol seemed to be able to be triggered only once, and it would be ineffective after being triggered.

Someone ran to Caitlin and asked, "What symbol did you find?"

But Caitlin just shook her head blankly, "I don't know."

…

Glancing at Caitlin who was surrounded by readers, Yu Dong smiled. In fact, when he set up this symbol, he had thought that it might be accidentally triggered by someone.

This symbol is very simple. In "The Da Vinci Code", one chapter mentions an "hourglass" symbol, followed by a sentence called "The best way to find the answer to a question is to ask the person who asked the question."

, and the collar of the clothes Yu Dong wore today was in the shape of an hourglass.

As long as someone asks Yu Dong for clues in person, or directly asks for a collector's edition book, this symbol will be triggered and a set of books will be obtained.

But this symbol can only be used once, and it will not work if someone finds it later.

There are many symbols in "The Da Vinci Code", some of which appear directly, and some of which are hidden in the text by Yu Dong. Some of these symbols represent a set of books, and some represent several sets of books. As long as the readers understand these new

information and find where the symbols are, you can hopefully get a set of collector's edition books.

Yu Dong did not hide these symbols in the book just for this activity. It was just that after he finished writing, he found a lot of things hidden, so he suddenly had a whim and decided to create such an activity to stimulate readers' interest in studying the book.
