Chapter 5160: Follow the law

Hao Lian became more proud after pulling out the bottom book.
"This is the ninth book, it's done!"
Ling Luoyu looked sideways: "Done?"
From visual inspection, it seems that there is no change.
Hao Lian also noticed that the bookcase was not moving, his smile slowly stiffened, "This..."
At this time, isn't the bookcase moving theoretically?
Why is there no movement at all? !
Ling Luoyu put down the book in his hand and glanced at Hao Lian sideways: "Is it something wrong?"
Hao Lian's face instantly turned red: "No... shouldn't it?!"
If it was really wrong, it would be a "slap" slap.
He was no longer joking, and quickly checked on the bookcase.
After a while, his movements suddenly stiffened, slowly turning his head to look at Ling Luoyu, his eyes moved.
Ling Luoyu saw the clue: "found it?"
"There is one... I don't know if it is..."
He moved a little away and pointed to a bump on the back of the bookcase.
"This may be the button to turn on..."
As he said, he raised his hand to click.
"Don't move!" Ling Luoyu quickly pressed his hand: "This button is on the second layer, as long as you are not careless, you can easily see it... If this is the case, then make so many nine digits. what?"
Expose this button directly, let people find it all at once!
Hao Lian also realized that something was wrong, and quickly withdrew his hands: "This is a blindfold... it is the hub of the agency that activates the backlash formation!"
"This is the easiest and the most low way to conceal your eyes. As long as you are a little calmer, you won't make such a mistake!"
"...What do you mean?"
"This hub should not be aimed at people like us, but the siren facing the prince and princess...As long as they enter here and press that hub, they will immediately trigger the alarm and attract the guards outside!"
As long as the prince and princess are a little curious, they will not miss this book pavilion!
Once they broke in and touched the button, they would attract guards instead of receiving fearless damage.
Hao Lian is inexplicably sweating
Isn't this just saying that he is overwhelmed and can't hold his breath?
From visual inspection, it is really so!
"Then... Miss Ling, do you know which way to open it?"
"The mechanism, it should be in the book you pulled out... Maybe something is wrong..."
Ling Luoyu knelt on the ground and took a close look at the bottom row of books, his eyes sinking: "In theory, the changes in these numbers can be changed with the changes in people's hearts, right?"
"of course……"
The mechanism is designed by people, and the deduction of this number is naturally free to do whatever one wants.
Just follow the rules!
Ling Luoyu raised his hand decisively and pulled out another book in the bottom row.
"Crack!"
The secret button sound of the agency suddenly sounded.
Hao Lian was half kneeling on the ground, and when he heard the movement, he jumped up instantly, raised his fists as if he was facing an enemy, and faced the direction of the door.
Ling Luoyu: "..."
Why are you so nervous?
Hao Lian raised his fist, seeing that there was no guard coming in the direction of the door, and he was a little bit astonished for a moment—
He misunderstood!
With the sudden change just now, he thought that the patrol outside had found an unusual sound inside, and the sound of rushing in!
Slowly lowered his head, facing the gaze that Ling Luoyu was looking up, he suddenly twitched his mouth.
"I...I'm doing a good job of guarding you!"
