That's why they left such a clue.

This time, the reason why Bai Qi didn't bring those people over was to see who this ghost was.

Since this book is so important to each other.

Then when they get the news of the book's address, the inner ghost will definitely try their best to inform the black side.

Therefore, it is very likely that the other party is already in this library.

Thinking so, Bai Qi looked up at the towering library.

The expression is unknown.

Su Tian's eyes flashed when he looked at Bai Qi's appearance.

"Let's go inside." Bai Qi retracted his gaze and said lightly.

After entering the library and having heating, Bai Qi let go of Su Tian's hand.

Before they came, they had already seen the structure of the library.

The first floor is a place to read and borrow books, and there is no study room.

And from the second floor, there are five study rooms on each floor, two large study rooms, and three small study rooms.

Other than that, it's where the books are kept.

Different floors are classified differently.

On the first floor are literary books.

On the second floor is a book on economics and management.

The third floor is devoted to Law and Sociology.

The fourth floor is history and fine arts.

The fifth floor is the other category.

According to the classification, this brief history of time is most likely on the first and fourth floors.

But obviously, Wang Rui could not have placed the book in a prominent place.

After all, the books in the library are taken care of every week, and if a book is misclassified, the administrator will put the book next to the same kind of book.

This makes it easy to find out.

So it must be an inconspicuous place that is easy to overlook.

"Boss, how to find this, so many books, so many layers, just the three of us, I'm afraid we may not be able to find it next year." Wu Hao frowned and said.

"Not so much." Su Tian said lightly, she looked around the library for a while, and then slowly said, "It should be on the first or fourth floor, literature and history." ”

"But even so, it's not easy." Wu Hao scratched his head and said.

"Well, you can have a student or a teacher help you." Bai Qi said lightly, "You are on the first floor, and Su and I will go to the fourth floor." ”

Wu Hao nodded helplessly, looking at the book collection room one by one with a bit of a blankness.

Here, Su Tian and Bai Qi were already walking towards the fifth floor.

Bai Qi firmly held Su Tian's hand and protected her in front of him, while looking around vigilantly.

Soon they reached the fourth floor, but instead of going to the fourth floor, they continued to go up.

I didn't stop until I got to the fifth floor.

Obviously, Bai Qi didn't fully believe in Wu Hao.

deliberately separated the three of them, and deliberately revealed the news on the fourth floor to Wu Hao.

Just to see if he is the mole.

"Why don't you doubt me." Su Tian whispered.

"Xu thinks that the girl who will heal Wang Cuiping's unbearable past, bring dinner to everyone who begs, and accompany me until the last moment when the bomb countdown must be a kind girl, in this case, how can she ignore the law and become an accomplice to the criminal." Bai Qi said with a smile.

"But..... It's probably all an illusion. Su Tian said in a low voice, "Why are you so sure." ”

"You girl, are you forcing me to say what is in your heart?" Bai Qi was helpless, "There's no reason, I just believe you." ”

Su was stunned, a little touched.

She could see the seriousness in Bai Qi's eyes, and she knew that what he said was true.

But because of this, she was at a loss.

After a pause, she looked at Bai Qi and said, "If it's not me, I will never betray you." ”

Bai Qi was stunned for a moment, smiled, and nodded.

Tightened Su Tian's hand.

The two of them didn't look at the other library, and went straight to the library at the end of the corridor.

The two soon found a book called "Time Knows" on a bookshelf in the last row, and when they opened it, it was "A Brief History of Time".

That's right, Wang Rui changed the costume for 3-11.

On the outside of the shell of "A Brief History of Time", there is another book cover.

If it weren't for Wang Rui's prompt, they wouldn't have been able to find the book even if they searched through the entire library.

Su Qian couldn't help but sigh at Wang Rui's intelligence.

Such a means.

Even if the other party turns the entire library upside down, it is impossible to find what they are looking for.

Who would have thought that this book, originally called "A Brief History of Time", would quietly become another one.

The two glanced at each other, Bai Qi put the book into his coat, and took a random book before going out of the library.

"Mom, ugly girl, did you find this book?" Xiao Tongzi's sudden sound startled Su Tian.

The corners of Su tilt's mouth twitched.

pressed it, and wanted domestic violence corporal punishment for the disobedient baby's feelings.

Only then did he slowly speak, "Naturally, I'm smart." ”

Xiao Tongzi: ........ Don't think he's still the same person he used to be, he's much smarter now than before, don't try to lie to him, huh.

Xiao Tongzi admitted that Su Qian was indeed very smart, but even if she could guess Wang Rui's technique, it was impossible for her to find this book that had been transformed so suddenly.

Su Qian snorted twice in his heart.

Stinky children are undereducated.

"Ugly girl Yin, you open your eyes and tell nonsense."

Hey, hey, and use colloquialisms.

Su Tian was a little surprised.

Ugh.

Baby, you're finally smart. Su Qian smiled and said, "Naturally, Wang Rui told me, and I am not a god, how could I guess this method at once." ”

"Do you still remember the brain map in her computer, it seems that there is only a simple case analysis on that brain map, and everyone will be shocked by the key to how many cases she really guessed."

"But I didn't, I knew from the beginning that she must have known that she was in danger, and that she knew what was causing danger, and that she would take certain measures."

"Since this is the case, then the other party will definitely put the information on it, and it can't be too obvious, obviously the other party will also come to check her computer."

"So not surprisingly, Xie Chen said that her browsing history was deleted twice, once she should have deleted it herself, one to prevent being discovered by the other party, and the other to tell the police that there is news here."

"But the other party obviously restored her records, but did not find the information she needed, so she deleted it twice, which is why her mobile phone was missing, but the computer was in the hands of the task force."

Because they need the task force to help them find the information, after all, the task force has "their own people." ””

"As for how to know the information, it's very simple, she uses a psychological hidden method."

"Deliberately putting key information in the blind spot of vision that humans will ignore, this means is impossible to see through unless you meet someone who understands psychology, so the other party doesn't see it."
