Princess Against the World

Pulling out a book from the bottom, Hao Lian became even more proud.

"This is the ninth book, done!"

Ling Luoyu glanced sideways: "Done?"

From a visual inspection, there seems to be no change.

Hao Lian also noticed that the bookcase was motionless, and his smile slowly stiffened: "This..."

At this time, isn't it a theoretical bookcase move?

Why is there no movement at all? !

Ling Luoyu put down the book in his hand and glanced sideways at Hao Lian: "Did I make a mistake?"

Hao Lian's face turned red instantly: "No... shouldn't be right?!"

If you really make a mistake, it will be a slap in the face.

He lost his sense of humor and hurriedly checked on the bookcase.

After a moment, his movements suddenly froze, and he slowly turned his head to look at Ling Luoyu, his eyes moving strangely.

Ling Luoyu saw the clue: "Found it?"

"There is one... I don't know if it is..."

He moved away a little and pointed to a bump at the back of the bookcase.

"This may be the button to turn it on..."

With that said, he raised his hand and was about to click it.

"Don't move!" Ling Luoyu quickly pressed his hand: "This button is on the second floor. Anyone who is not careless can easily see it... If this is the case, then there are so many nine-digit numbers. What?"

Just expose this button so people can find it at once!

Hao Lian also realized something was wrong and quickly withdrew his hand: "This is a deception... it is the hub of the mechanism that activates the counterattack formation!"

"This is the simplest and lowest deceptive method. No one who is calm enough will make such a mistake!"

"……What's the meaning?"

"This hub should not be aimed at people like us, but an alarm for princes and princesses... As long as they enter here and press the hub, the alarm will be triggered immediately, attracting the guards outside!"

As long as the prince or princess is a little curious, they will not miss this bookstore!

Once they break in and hit the button, they'll attract guards instead of taking no damage.

Hao Lian was inexplicably sweating——

Doesn't this mean that he is getting carried away and can't keep his temper?

Visual inspection shows that this is indeed the case!

"Then...Miss Ling, do you know any way to open it?"

"The mechanism should be in the book you pulled out... maybe there is something wrong..."

Ling Luoyu half-knelt on the ground and looked around carefully at the books in the bottom row, his eyes darkening: "Theoretically, the changes in these numbers can change with the change of people's hearts, right?"

"certainly……"

The mechanism is designed by humans, so the deduction of these numbers can naturally be done as one wishes.

Just follow the rules!

Ling Luoyu raised his hand and decisively pulled out another book from the bottom row.

"Click!"

The sound of a secret button suddenly sounded.

Hao Lian was half-kneeling on the ground. When he heard the movement, he jumped up instantly, raised his fists as if facing a formidable enemy, and pointed in the direction of the door.

Ling Luoyu: "..."

What are you so nervous about?

Hao Lian raised his fist, and when he saw that there was no guard coming from the direction of the door, he suddenly felt a little confused——

He misunderstood!

With that strange sound just now, he thought that the patrol outside had noticed something unusual inside and rushed in!

Slowly lowering his head, he met Ling Luoyu's gaze looking up at him, and immediately twitched his mouth.

"I...I am doing a good job as a sentinel for you!"
