"By the way, I get it."

Yao Ruixue suddenly walked to the edge of the bed, counted the stones, then knocked on every two stones, and then went to the other side every three stones. Sure enough, he heard a click, leaning against the front of the table placed on the wall, and moved away a stone door again.

"So, the master has really told me the password."

Since the bedside was Shi Che, and the number of blocks was clear, Yao Ruixue remembered that she was about ten years old. Her master played a guessing game with her, and each time she hit it, it represented a number.

Therefore, after seeing the particularly exquisite mechanism lock behind the stone door, Yao Ruixue is easier to open.

The mechanism lock looks exquisite and tall, but does not require a key.

"Stone, lend me your saber, I know how to open this door."

Shi Hongfei handed her the knife and told her to be careful. Yao Ruixue actually wanted to use a saber to cut Lu Feng's fingers and wanted to use his blood to open the door, but she was a little hesitant at this moment.

The master once mentioned that some mechanism locks can only be opened by their own blood relatives.

If not, if the attempt fails twice, the lock and the unlocker will be destroyed.

The master didn't say how to destroy it.

What she hesitated was that if the result of her test today was as she had guessed, then her brother-sister relationship with Lu Feng would have come to an end.

If she doesn't try, she can only guess forever.

"What's wrong with the little girl?"

Lu Feng saw Yao Ruixue's hesitation, and even after she got the saber, her hands trembled a little, and the look at him was a little complicated.

Shi Hongfei also understood it and finally confirmed again that his Wanwan had really hidden a lot of things from him.

Otherwise, at this moment, she shouldn't hesitate.

After all, the results they guessed were the same. Opening this door should be the real way to the vault and the way to go out.

"Wanwan, do you want blood?"

Shi Hongfei grabbed Yao Ruixue's trembling hand and wanted to hug her and comfort her excessively swelling emotions, but Yao Ruixue avoided it.

Yao Ruixue opened her mouth and finally chose to use her own blood.

At this moment, whether Lu Feng was her own brother or not, she had already regarded Lu Feng as her brother who had only grown up for a few minutes.

So, whether he had his blood test or not was the same result.

"Well, the blood of the Qi family inheritor can be opened."

Therefore, after Yao Ruixue told Sun Jin about the location of the vault in his previous life, they had not found it for a long time. Before she got the more than 50,000 books, she was once again sucked a lot of blood.

She guessed it should be used to unlock this lock?

The result was wrong, because she cut her fingers without any fear of pain and dripped them directly into the three holes of the lock of the mechanism.

As soon as she dripped, her fingers were taken into her mouth by Shi Hongfei, and her eyes showed tenderness and care.

There was a loud roar, and the door locked on the machine automatically opened.

Looking around, I don’t know, but I thought I had entered a library of a university.

There are all study rooms, neatly arranged, one horizontal and four rows, one row of ten frames, and each bookcase has fifteen floors of bookcases, and each frame is full of books.

There are more than 50,000 books on it!

There are only 500,000 books!

She was cheated in her previous life!!!

"Wanwan, does it still hurt?"

Shi Hongfei didn't care what was inside it. He just wanted to know whether it hurts if his Wanwan put so much blood on her hands.

If he could, he was willing to bleed on her behalf.

"Is it uncomfortable somewhere?"
