Aunt Stella's villa is luxurious enough.

Chen's mother cleaned up several rooms, and Jiang Bai and they were able to have a single room for each person!

In the room, Jiang Bai simply placed his luggage and looked out the window.

Due to the high enough height, you can look out from the mountain road.

The view of Kyoto is still in full view from this location.

Looking closer from the distant view of Kyoto, Eoha noticed that the lattices of these meadows were very regular.

From left to right, there are basically several field shapes, except for the color of the grass in the upper left corner of each field grid is slightly darker, and the color of the other grids is almost the same.

Think back to when you entered the door and when you opened it.

All have such signs.

Stella also repeatedly explained that this was not some family coat of arms, and that it was probably some hint.

"Jiang Bai, let's take a look together, maybe you can find something in the villa!"

He Dazhuang pushed open the door and said, he had already pulled Du Yiheng and Yan Xiyue, "We can't be looked down upon by that broken reporter!" ”

He has been provoked by Li Qiming, and now his enthusiasm for cracking the code is very high.

Jiang Bai had no intention of arguing with Li Qiming, he had nothing to do with him.

But the code of the letter really needs to be cracked, and Jiang Bai has no objection to everyone working together.

Afterwards, the group first learned about the villa under the introduction of Chen's mother.

The three-storey villa consists of a cellar.

Whether it is the hall or the study room on the first floor, including some mirror rooms used for fitness, they all look quite luxurious.

It can be seen that Stella's aunt should be a person who knows how to enjoy herself.

And the master bedroom on the second floor, including many guest rooms, can also be seen, she is very hospitable.

However, Jiang Bai noticed that some decorative vases and sculptures had the symbol of the shape of the field on the side.

The square in the upper left corner is blacked out, or the top left corner is left blank in all black.

"That should be a hint."

Du Yiheng said, "Stella said that if it is not a family crest, it should have other functions. ”

Not only did Jiang Bai find out, but under Du Yiheng's prompting, He Dazhuang and Yan Xiyue also began to think about the role of this sign.

"Could it be the location of any room?"

Yan Xiyue said, "I see that there will always be a secret door in a big villa like this in the TV series. ”

"It's a pity, Miss Yan, I've lived here for so long, and I haven't found any secret doors."

Chen's mother, who led the way, said, "But I don't know when these signs were put up." It should not have been before. ”

"What about the lawn?"

Jiang Bai asked, "The lawn should have been built very early." ”

"Huh? What about the lawn outside? ”

Chen's mother was stunned for a moment, "Yes, it was my wife who said that it was beautiful at the time, but it wasn't really done until my wife didn't see her not long ago." ”

She then explained, "The main thing is that dark grass seeds are particularly difficult to grow, and we have to change them several times to get them right. ”

Hearing this, Jiang Bai began to think about a possibility in his heart.

Assuming that the grass, including these signs, were clues related to passwords, then two years ago or even earlier, Stella's aunt had already begun to prepare these.

"Okay, then let's go to the third floor."

Chen's mother said that she was going to take everyone to the third floor to visit.

"Mother Chen, can I go to the study?"

Jiang Bai asked.

"Yes, Mademoiselle has already told me that her friends can come and go as they please."

Chen's mother nodded and said, "Jiang Bai, don't you want to visit the third floor?" ”

"Just go."

Jiang Bai said lightly, "Remember to observe carefully." ”

After that, Jiang Bai went straight downstairs and came to the study.

He felt that since Stella's aunt might be interested in passwords, she probably had some books on them.

According to the relevant password knowledge that Jiang Bai saw before, only if the person who knew the password learned what methods he had learned, it was possible to crack the password in a silent state.

The multiple passwords that Du Yiheng showed himself last time were actually incomplete.

The original case found by Jiang Bai on the Internet is a version with relevant tips.

Without hints, cracking is like exhaustive methods, try as many kinds as you want.

Just like brute-force cracking a combination lock, try everything from 1234 to ABCD.

But the human brain is not a computer after all, and it does not have such rapid computing power.

When he came to the study, the layout of the bookshelves also made him feel strange.

Each bookshelf is a large bookshelf in the shape of a field, with a cabinet underneath.

In the upper left corner of the Tianzi shape is a book with some dark covers.

Jiang Bai took a closer look at the collection of books, full of books studying passwords!

In addition to Morse code, there are also some books on binary, polygonal principles, and even the general theory of cryptography.

It seems that Stella's aunt is not only a crypto-loving person, but also a deep "expert".

Jiang Bai didn't have that much time to go through them all, but at least he could take pictures of them.

From large to small, various ways to compile passwords, in addition to the binary and polydecimal systems seen at a glance, Jiang Bai also found that there are the application of mobile phone nine keys in cryptography, the influence of ASCII code tables on password compilation, and the structural changes of numbers and alphabetical order.

He hadn't learned passwords systematically, so he didn't know whether these were basic or high-end.

But at least she had mastered a few of the methods that Stella's aunt was supposed to use.

On the desk, Jiang Bai saw a special board for books, which was still the familiar sign.

It was everywhere and seemed to be constantly reminding him of something.

Jiang Bai closed his eyes and thought about the location of the study, there were still many walls around it, but they were all relatively thick.

Having the experience of the old houses he encountered on the previous show, he felt that some of these walls might be hollow.

Perhaps there is a secret door in this huge villa.

And these signs are the way to open the secret door?

Thinking of this, he began to knock on the wall.

Listen to the sound, the middle of the wall is empty.

It's a pity that Jiang Bai didn't know the location of the organ.

From other angles, these walls should be thick enough for one person, or at least enough for one person to walk sideways.

He walked out of the wall of his study and began to experiment with various walls.

To his surprise, many of the walls felt empty when they were knocked on.

But after searching the first floor, he couldn't find any mechanism.

Except for the kitchen and other places that are basically impossible to go.

Back on the second floor, Jiang Bai saw that Chen's mother was taking them down.

"Jiang Bai's third floor thief is excited, it's a pity that you didn't go."

He Dazhuang said excitedly, it seemed that he had forgotten his previous ambitious things.

"It's actually some live-action simulation game."

Du Yiheng said, "Does Stella's aunt like to play games? ”

"No, these used to be what the master liked, and since the master left, the wife moved these upstairs."

Chen's mother sighed as she spoke.
