[Quick Transmigration] The Truman Show

What are twin primes?

Mathematicians have given such a definition: from black hair to white hair, they are the closest prime numbers, but the distance between them is always 2, which is the twin prime number.

300 years later.

An unknown painting was auctioned for a sky-high price in the L province of the empire, setting a record for the highest price in the history of modern painters in the empire.

Initially, the painting did not attract people's attention.

It doesn't look amazing at first glance, and there is no signature, only a date in the lower right corner: March 191, X3.

Classic one-point perspective composition, the buildings on both sides of the path converge toward the middle of the invisible vanishing point, and there seem to be five blurred points near the end of the perspective vanishing point.

The entire oil painting is full of oppression, dark sky, dark and heavy, dark clouds, terrifying and gloomy.A straight path in the center of the picture is paved with a real mirror.Along this path, from near to far, there are row upon row of old houses on the left side, painted with inks of various dark colors in a mess, the houses are tall and short, but almost every one of them looks narrow and distorted. It looks like a screaming grimace, but also like a burning flame; while the wall formed by the vertical light and shadow distorted by time and space on the right side constitutes the only light source of the picture.Perhaps due to the existence of the light source, the small road made people feel hopeful. The sky reflected in the mirror on the ground was not dark, but unexpectedly bright and beautiful.If you look carefully, you will find that the mirror on the ground reflecting the evening clouds is actually a jigsaw puzzle with a few pieces missing.

It was such a weird, but not very amazing oil painting that caused a sensation throughout the empire.

The cause of the matter is Morse code.

Some people accidentally discovered that behind the lines that make up the windows, doors, and jigsaw puzzle outlines of ancient buildings, there is actually a complex Morse code hidden.

The point is, the cryptographers of the empire couldn't crack it.

Cryptographer, "The houses on the left side of the path are different in height and height, the lines representing doors and the windows representing points all have obvious fluctuations in length, and there are jigsaw pieces that are missing in the mirror on the ground. In this painting There are at least two sets of Morse codes. But, you know, spaces are also part of Morse code. Without spacers, we are using computer programs to try every possible way to divide..."

This discovery completely ignited the gossip of the melon-eaters in the empire and experts and scholars in various fields.

The first is the restoration of cultural relics, calligraphy and paintings of the empire.

Near the end of the vanishing point, what are those five fuzzy points?

They used state-of-the-art technology to improve clarity, and used real-scale 165D space modeling to restore the holographic image of the painting: there are a total of 1000 buildings on the left side of the road; five fuzzy points near the vanishing point are zoomed in [-] times, it turned out to be five exquisite and high-quality micro-paintings.

Each miniature painting is a clearly visible back view of two men.

Five groups of backs, five periods, from black hair to gray hair.

The cryptographers of the empire were a little frustrated, but the mathematicians of the empire were happy.

They taunted the cryptographer with joy: "We discovered an interesting fact. After the perspective angle is corrected, there is a prime number sequence whose first term is 3 in the width of the building complex on the left: 3, 5, 7, 11, 13 , 17, 19, 23, 29, 31, 37, 41, 43, ... 991. Each building is just located between two prime numbers. For example, the width of the first building is 2 (5-3), The first building has a width of 2 (7-5), the third is a width of 4 (11-7)..."

与浪漫不搭边的数学家，又傲娇地对公众宣布：“我们发现了油画里五组非常浪漫的数字——809和811；821和823；827和829；857和859；881和883。”

The people who eat melons are surprised: "Where is the romance of these five sets of numbers?"

Someone took the initiative to answer the question: "These are five sets of twin prime numbers."

The five miniature paintings, in the holographic image, are the backs of two men, always one in front and one behind.

In the first group of backs, both of them still have black hair, and the numbers corresponding to their positions happen to be 809.

接下来三组背影，821和823；827和829；857和859，一个人始终是黑发，另一个人的头发逐渐开始变白。

Until 881 and 883, both of them had gray hair.

If the vertical light wall with space-time distortion on the right represents the passage of time, the prime number sequence in the building complex on the left just provides an accurate reference.

Someone asked, what are twin prime numbers?

Mathematicians have given such a definition: from black hair to white hair, they are the closest prime numbers, but the distance between them is always 2, which is the twin prime number.

Prime numbers are lonely because they are only divisible by 1 and themselves.But twin primes are lucky again, because they are almost close to each other, almost next to each other.

But only almost.

Some people are silent, some people cry.

Everyone is eager to know——

Who are the two people in the oil painting?

Why encrypt with a password?

What is the relationship between them?

It's as if a huge secret is right in front of you, tempting you to move around, but you can't find any clues.

The painting is unsigned, and little information can be found other than its date.

……

On the other side, the cryptographers secretly stared at the prime number sequence discovered by the mathematicians, and suddenly had a flash of inspiration, "The prime number sequence! It turned out to be a prime number sequence! The Morse code can be divided according to the prime number sequence in the painting." It turns out that this is the case, this painting is so clever! If the division method is determined, then——

Morse code for house height, windows, doors:

.----/...--/-----/...../-----/.----/...../....-/-- --./-..../.----/.----/--.../...--/-..../.----/...- -/..---/--.../--.../.----/-----/..---/....-/-----/ --.../...--/----./-----/-----/-----/...--/-----/.. ..-/...../----./----./...../---../---../-----/---- -/...../-..../....-/----./--.../.----/....-/.----/ ...--/...--/-----/.----/...--/----./

Ciphertext: 13050154961173613277102407490003045995880056497141330139

Morse code in the silhouette of a jigsaw puzzle above ground:

..---/-..../..---/...../..---/---../---../--.../.. ..-/----./...../-----/-----/.----/--.../-.../

Ciphertext: 2625288749500176

There is no doubt that this is multiple encryption.Fence maybe, Caesar maybe, but no keys, not even sure how many layers of encryption, still too many characters to be sure..."

The author has something to say:

This password is not difficult, and you can guess the key. If you are interested, you can restore the plaintext based on the number (the plaintext is not English or pinyin, but Chinese characters); there is a reason why cryptographers can’t decipher it.

Wait for one more.
