Le Zhengling is the first time to enter the family's study, you must know that this family study is now a cyst for her, and thanks to Ye Xi'en, she used the heir gold leaf to exchange the information left by the prophet, but with the prophet's Le Zheng's grandmother Le Zhengyin and Zhao Lingxi are no different from mortals in comparison, she has nothing to make up for her mistakes with existing resources, she thought for a while and said: "Boss, is there anything else I can do?"

Jiang Tianyi's mansion, the size of a bathroom is the size of the master bedroom of an affordable house, the double-cylinder sink is sprinkled with cherry blossom petals, and the faucet is made of 24K gold to ensure that the washing water that flows out is very active, she reached into the washbasin and turned around twice to adjust the water temperature, while saying: "Not for the time being." The Ye family's housekeepers are very careful, and besides, which 'Pandora's Magic Box' really can't be opened casually. There is absolutely no way that you will be able to find valid information from the prophet's study before you have given birth to an heir to their family.

Now that we have only found Zhou Muyun, the smoke and rain and the only parting are still missing, you can know how high Alberti's intelligence level is, it is simply looking down on all beings from the perspective of a god, and it is too difficult to surpass this artificial intelligence designed by Zhao Lingxi, I think, I still bet on the immortal. ”

"Okay............" Le Zhengling sighed and closed the video communication line.

Ye Xien was still napping on the sofa in the living room outside the prophet's study in the main house of the Le Zheng family, he thought that Le Zhengling would come out of the study soon, but he didn't expect that it would take her 2 hours as soon as she entered. The housekeeper of the Lezheng family didn't dare to alarm Young Master Ye Xien, and gently took a double-sided fluffy blanket and covered him.

The family rarely picks up this eldest lady in the real sense, and now when I see her coming out of the study, I am in a trance that the future of the Lezheng family has been firmly pinched in her hands, no matter how little she has taken over this study for less than 2 hours.

The Lezheng family dismantled the Alexander family's manor house piece by piece from Germany and reassembled it in Sui City, Nanyue Province. This kind of move is unprecedented in the antique world, but compared to the Alexander family's manor, it is really not enough to see.

The Lezheng family's collection of antiques is ten times that of the Alexander family, and when it came to cleaning up antiquities, more than 5,000 antique appraisers and offline technicians were used, which was sensational news 100 years ago.

In the corridor of the original house, there are photos of violin, piano, guzheng, and guqin making technicians of the Lezheng family for three centuries, some of which are oil paintings, some of which are taken with rifle cameras, and some of which are scroll paintings.

Le Zhengling lingered in the prophet's study, and he couldn't bear to leave. But she also knew that after such a long stop, Ye Dagongzi would definitely complain, so she set off to the hall of the entrance.

The main residence of the Lezheng family is called Linshui Zhaohuazhuang, which was built in the Daoguang period of the Qing Dynasty, with a combination of Chinese and Western styles, and the appearance is copied from a combination of green glazed canopy French houses in the Old Summer Palace.

It is said that the overall design drawings were obtained from the family of architects, so the idea was extremely exquisite, especially in the largest room of the main house, the Prophet's study, which has twelve consecutive Karakuri locks, and once destroyed, mercury fills the entire room.

Equipped with a 360 revolving door in the yin corner of the room, it can help the owner escape, it is really like the invisible door mechanism mentioned in the martial arts, its security ability is two-way, and no opponent has been found in the entire Nanyue Province.

The information registration and sorting method of Le Zhengjia is to follow the password method of Shanxi Qianzhuang, plaintext + ciphertext + note reverse cutting method, and its decipherment difficulty is tantamount to the world's first, which is more than 400 million changes in pronunciation rules than the English code password of the German legal name during World War II, and does not use any radio waves as an aid, so the plaintext is also considered a ciphertext.

In order to prevent any outsiders from finding out the rhythm of the music, the family will alternately use the rhythm ordering method of various classical instruments as the basis for the note pronunciation and cutting method every year, so it is not enough to be proficient in mathematics, but must have a good understanding of the pronunciation rules, vocal range and variation rules of all classical instruments in each stage of history.

For example, in 2026 AD, when the Le Zhengjia uses cello pronunciation, then the pronunciation rule chooses the counterpoint method, and the form of creation is a fugue, so the 3rd or 4th movement of a certain fugue of Bach is randomly selected as the basis for calculation.

The counterpoint method is to create the tone to the tone according to the rules, so the password is to combine different tunes at the same time after determining the tone to the tone, so that the music and the code can maintain the independence of each voice itself and the contrast and connection between each voice in the horizontal direction, and can constitute a harmonious effect in the vertical direction.

In short, the way to unlock the code is a piece of music. The specific method of reverse deduction is as follows: the first step is to determine the music composed in the current year, which is in plaintext, and the instruments used and pronunciation rules are matched by the plaintext. In the second step, after the plaintext is converted into ciphertext, you can use the ciphertext to understand the specific location of the content you want to find. The third step is to interpret what the content of the record says through the reverse cutting method.

And in the process of deciphering all this, we must think that if you see with the naked eye, touch it, and listen with your ears, if you hear a wrong note, all the subsequent deductions will be wrong.

This kind of information transmission method requires the decryptor to have an absolute sense of sound is only the foundation, and the listener must also maintain a high mental arithmetic ability, and must also listen to all the notes in a single time, and the calculation method is very close to the lightning algorithm form of double brain mental arithmetic.

Mental arithmetic is a method of synchronous calculation of both hands and brains obtained from the abacus, and the pronunciation law is similar to that of mental arithmetic.

Under the inheritance of hundreds of generations of the Lezheng family, the encrypted calculation method not only adds mental arithmetic, but also puts listening and musicality into it, especially the more classical the creation method, the more difficult it is to crack at will, because the more musical wisdom condensed in it.

Relatively speaking, Le Zhengjia has made the mathematical part of music to the extreme, so things such as electronic music that Le Zhengling fiddles with are just leftovers from the ancestors.

Le Zhengling entered the study of the house through his mental arithmetic ability, and only then did he really pass the assessment of the heir of the Le Zheng family.

In the space of two hours, she realized that all her previous efforts were like child's play in the eyes of her grandmother. Of course, being able to decipher the descendants who entered the Prophet's Study through her own abilities also fully proves her strength, and her performance in every link is extremely outstanding, so it doesn't matter if she has a family badge or not.

Le Zhengling came to a conclusion by carefully looking at the pronunciation rules of electronic sounds - the more modern it is, the simpler the structure. The Lezheng family appears to be a musical instrument dealer who manufactures classical music equipment, but in fact it is a screw for the ruling class to carry out information transmission and preservation services.

As an effective means of information transmission, music is very suitable for transmitting messages in public, and unlike radio waves, sound waves will be deviated due to the relationship between different mediums, so this kind of plaintext is also encrypted plaintext.

After the Second World War, the fact that the Ingma code was cracked by Turing became known to the world, and the ancient method of not pursuing efficiency and speed was reactivated. If you only preserve and continue the data on the premise of not fighting information warfare and speed warfare, this encryption method of the Lezheng family can basically be regarded as one of the strictest secrecy methods, but well, the world still has to pursue efficiency, so the frequency of use of the prophet's study is getting lower and lower.

In the Celestial Empire, there were only three prophets' studies, and the encryption methods of these three prophets' studies could not be interconnected, that is, they were independent of each other, and the information did not intersect. The first place is the basement of the Liansheng Courtyard in Xicheng, the Tiandu where Ye Xien's grandfather is located. The second place is in the west city of Sui City, Nanyue Province. The third is at the Annis Dora Castle in Yuhang, Zhejiang Province.

Among them, Annisdora Castle is the last to be built, the world's most rigorous encryption system, the most perverted difficulty of the study, its completely 3D printed building, less than 20 years old.

The name Annistora may sound unfamiliar, but Annistora's nickname is familiar to everyone, Pandora, and it is also a kind of counsel from the prophet to the world, saying that if the secrets stored in this castle are spread, they will bring disaster.

So the third prophet's study is also called Pandora's Box.

The structure of the third study is very special. Because it is a 3D printed house, there are no artificial construction workers involved in the construction process, that is, how it is constructed is a secret, and inside the magic box is a huge secret room.

The entire building of Annistola Castle has an above-ground construction area of 17,711 square meters, an underground construction area of 28,657 square meters, and a total area of 46,368 square meters, which is the perfect golden ratio and the first castle in the world that fully conforms to all beautiful mathematical proportions.

Annistola Castle is not very large, but it has only one exit from the inside out. There are a total of 377 rooms inside, each of which is a storage room, and each storage room is moved according to the track at regular intervals, and the movement of the entire interior space of the building is regarded as an encrypted form.

Every time an attacker arrives, the pantry is rearranged and combined, just like the real 9 squares, but more varied than the 9 squares, because 377 is the Fibonacci number, which can be changed according to the way plants and animals are bred in nature, multiplying a total of 377 times the existing mammals and plant breeding laws.

The Fibonacci number is also called the golden section number, although there are many variations, but it is very easy to calculate for today's electronic computers, and it can be cracked by finding out the law.

But if you want to get out of the prophet's study, it is always a combination of intelligence and physical fitness, the physical fitness required by the Lezheng family is hearing, and the physical fitness required by the Ye family is agility.

There's no way a nerd can't live to get what he wants from an unpredictable and super-fast-moving castle and get out of it quickly.

Annistola's Castle is worthy of the title of the magic box, with no water, no food, not even a restroom. Stupid waste wood will either die inside, or quickly surrender and wait for rescue. This is just the venue encryption, other encryption methods, such as the note reverse cutting method used by Le Zhengshi's family, are found in every room in this magic box.

As perverted as you want, you can be as perverted.

Annistola is a world-class castle that can be visited by mathematicians and decryption enthusiasts from all over the world. However, you have to bring your own drinks and are not allowed to defecate in the open, you have to sign various exemption clauses before you go in, and you have to experience the process of wrestling with supercomputers and physical fitness at the same time, so fewer and fewer people are involved.

After Le Zhengling came out of the prophet's study, she saw Ye Xien lying on the sofa and falling asleep, she walked to the entrance and stroked a grand piano in the entrance. This piano is a pure antique, and unlike the mass-produced Steinway, it is a product of the grand piano before its inception – a long piano that is so precious that it should be put on a museum.

This piano is already about 280 years old, not lacquered, so the texture of the wood is very clear, over time, the wood has become very compact, showing a dark red, with the embossed pattern, extremely beautiful.

Le Zhengling looked at the nameplate on the piano tripod, which recorded the top red acid branch wood mined in France in the origin of the wood, the piano legs and covers were all hand-carved, and the technician was Silberman.

Le Zhengling couldn't help but gasp, the value of all the antique instruments she had seen in her life was not as expensive as this piano. The ornate patterns and magnificent appearance are breathtaking. The piano has two lifelike angels carved directly above the keys, and two layers of lace are engraved on either side of the keys to show its former owner's status.

There is no doubt that this is a royal piano. The person who used this piano was either the emperor or his eldest princess. There are many characteristics of the piano used by the royal family, and its most obvious feature is the large number of decorations.

The royal piano is heavy on beauty and light sound quality, and the sound quality effect will be lighter than that of the modern Steinway & Sons, as a professional craftsman, it is very strange to put such a piano in the entrance hallway, after all, the preciousness of the piano cannot be used as a hallway furnishings, and it should be put in the study.

The style has nothing to do with the quaint furnishings of the whole house, and as a matter of history, they can find a piano with a better tone to assert their place in the musical empire.

Le Zhengling opened the lid of the piano, and the ivory keys came into view. The keys are old, and because they are made of animal bones, they have weathered a dense layer of rich dark yellow, and it is impossible for modern pianos to make keys made of ivory. One is for the purpose of protecting animals, not using animal bones to make keys, and the other is that the maintenance of ivory keys is really problematic, in a hot and rainy province like Nanyue Province, the impact of the climate on this bone piano is doubled in the moldy season.

Who made the ivory keys the absolute best in the hand? The ivory keys have a rough surface and a perfect coefficient of friction that does not stick to the fingers.

Le Zhengling looked at the piano, and then looked at the big butler of Le Zheng's family, a mysterious smile appeared on the corner of his mouth, and made a gesture of please. This means that the trial is not over, and this piano is also an exam question.
