The numbers above are very interesting, they are self-descriptive.

In other words, the numbers are self-descriptive.

There is a saying circulating in Terra's academic circles: "If I had only one hour to save Terra, I would spend fifty-five minutes defining the problem and only five minutes looking for a solution." ”

A qualified academic researcher attaches great importance to the methodology of problem solving, especially the importance of defining the problem and understanding the problem accurately.

And this applies especially to all thaumaturgists in Terra today.

In today's Terra, where genealogical networks, think tanks, and pan-AI are proliferating, it will be more important to ask questions and how to better ask questions than how to solve them quickly and conveniently.

In the realm of thaumaturgy, the explosion of genealogical productivity has gone beyond the imagination of individual limits.

The problem is more important than the problem solved, and this is the innovation that technology brings.

So, the first thing to do to understand the meaning of the numbers on the door is, of course, to define the definition.

The above number can be understood as: "self-descriptive number".

A self-descriptive number, as the name suggests, is a number that describes the characteristics of the number itself through the number itself.

To sum up this kind of self-description through the number itself, that is, the number on each digit of the number is the number of times the numerical value of that digit appears. (The number of digits starts from 0, from left to right, and so on)

Xia Xiu was keenly aware of the characteristics of the numbers above, and each single digit of these numbers could accurately describe the characteristics of the number itself. More specifically, in a self-descriptive number, the number on each bit indicates the number of times that digit appears in that number.

Take this set of numbers, for example: 1210

The number in the 0th digit is 1, which means that the number 0 appears 1 time in the whole number.

The number in the 1st digit is 2, which means that the number 1 appears 2 times in the whole number.

The number 2 in the 2nd digit is 1, which means that the number 2 appears 1 time in the whole number.

The number in the 3rd digit is 0, which means that the number 3 appears 0 times in the entire number.

The number in the 0th digit = 1, so 0 is only once ("1" 210); The number in the first digit = 2, so the number 1 appears twice (1"2"10), and so on, the number in the second digit is 1, so 2 only appears once (12"1"0), and the number in the third digit is 0, so it means that it appears in the integer number as 0.

To sum up, 1 0, 2 1, 1 2, 0 3, and then arrange them according to the self-described characteristics.

Therefore, the number on the [Vitruvian door] must now be filled in with the characteristics of self-descriptive numbers. , the number shown on the number lock slot above is: 32████0.

The number in the 0th digit is 3, which means that there will be 3 zeros in this set of numbers, and a "0" has been seen on the door, so there are two more positions with "0".

The number in the first digit is 2, which means that there will be 2 1s in this set of numbers.

The number on the last digit is 0: this indicates that "6" does not appear in the number.

Since he already knew the numbers of the 0th and 1st digits, Xia Xiu could already determine that the remaining four digits contained two "0s" and two "1s".

At the same time, he can exclude the appearance of "6", so that the rest of the numbers can only be "2", "3", "4", and "5".

Depending on the nature of self-describing numbers, the number of occurrences of these numbers must match their position in the numbers.

Now you can analyze the remaining positions directly:

If "2" appears in a number, it must appear twice. But there is only one 2 on the door, so the "2" only appears once.

"3" appears at most once, because the third digit is already a different number.

"4" and "5" do not appear since there cannot be four or five numbers 4 or 5 in this number.

So, there's only one answer!

The blacked-out part can only be "1100" because it ticks all the boxes.

So the full number is "3211000".

After deducing the answer, Xia Xiu directly started to turn the digital lock on the [Vitruvian door].

And the above inference process is placed on a macroscopic time scale, and not even a minute has passed, so Xia Xiu's sudden turn of the number slot has frightened a certain legendary hunter who is engrossed in staring at the portrait of [[Vitruvian Man].

"What are you doing!?"

Bazin, who had been engrossed in observing the door, heard the sound and stared back.

Then, panic crawled across his face.

He stared at the Fourth Sword Bearer of Heaven with a look of astonishment, his eyes fixed on the turning door in front of him.

Under Bazin's gaze, the blonde youth's fingers slid lightly over the number slot, and he seemed unafraid of this seemingly intractable mystery.

With each turn, a number was accurately positioned on the space, gradually forming a four-digit number, and the blonde youth operated so quickly and confidently that it was as if he already knew the code.

Bazin panicked because this number lock only had three chances to try.

Once the number of attempts is exceeded, the lock locks permanently, preventing them from entering the space behind the door.

For Bazin now, the clues of the Land of the Sea of Fog are more important than his life.

The man-made island was destroyed by the sea monster, his companions were invaded and corroded one by one, and died tragically in front of him, while the people who should have been protected by him died in a foreign land, but he "survived".

Since he survived, he had to find justice for all who died.

In the face of Bazin's amazement,

The blonde youth's expression remained calm, as if he was convinced of his judgment. at

After entering the last number, he gently pressed the confirmation key.

Bazin held his breath and nervously waited for the results.

There was a slight "click" sound, and the door lock was successfully unlocked.

Bazin had an expression of disbelief on his face, he could hardly believe what was in front of him.

The blond young man turned his head and smiled at Bazin, and he tapped his right index finger lightly on his temple, and said with a smile:

"Please, the angels of heaven are not reckless, we all eat by our heads."

“········” Bazin's heart was instantly speechless.

This sentence came out of the mouth of the angel of heaven, how awkward he sounded, but he couldn't refute it now.

An unusually subtle thought held in his heart, making him feel a little uncomfortable.

"Let's go, let's see what the hell Pedro Miguelsette is up to."

Xia Xiu pushed open the door and said to Bazin, who had not yet reacted, and then he took the lead in raising his feet and stepping into the door.

Bazin immediately reacted from his stunned state, and when he saw the blonde young man walking in first, he immediately took out his thaumaturgical handcuff, and after activating the pre-made thaumaturgical bullet, he also followed him into the door.

***********

In a laboratory with a gloomy atmosphere, there is a heavy and mysterious atmosphere in the air.

The light bulbs embedded in the walls of the laboratory flickered on and off, flickering with an unstable light, creating an eerie and unsettling atmosphere in the laboratory.

The light casts long shadows with each flicker, making the space even darker and more oppressive.

Buzz –

A special door suddenly appeared from the void, and then, the door opened, and a handsome young man with blond hair and golden eyes stepped out of it.

When Xia Xiu walked out of the [Vitruvian Gate], his nose was slightly wrinkled, and a peculiar smell filled the air.

The first thing you smell is a unique and pungent scent, formalin, which mixes with other scents in the air, such as a slight metallic cold scent and subtle notes of mechanical grease, to create an impressive ambience.

Xia Xiu's golden eyes couldn't help but look at the laboratory in front of him.

Under this flickering light, rows of circular biostorage vessels were arranged, each filled with a clear green nutrient solution.

Floating quietly in these vessels is a strange creature.

Their bodies are slender, and their transparent skin is more visible in the nutrient solution, with their delicate muscle textures and slow-flowing blood faintly visible.

The surface of these creatures is inserted into tubes that fluoresce with data.

One end of the tubing is connected to the complex equipment of the laboratory, and the other end is deeply inserted into the living organism. These pipelines glow a faint blue glow under the lights, giving people a futuristic sense of intertwined technology and life.

In the corners of the laboratory, various instruments and monitoring equipment operate quietly, and complex data and charts are pulsing on the display screen, recording the life activities and experimental processes of these creatures.

【Tomb of Miguel Set】

A conspicuously unusual word appears at the top of the display.

Buzz –

Bazin followed suit in the gloomy laboratory known as Miguel Set's Tomb.

"Here?" Bazin clutched the [ebony] and [white ivory] in his hands, and his eyes were quickly drawn to the rows of strange utensils in the laboratory.

[Finally, a living Terra human has arrived!] 】

[Thaumaturgical handcuffs, you are the hunter of the [Hall of Hunting]!! 】

[Pedro's distress signal has finally been successfully transmitted to Terra-]

The voice of ecstasy suddenly sounded in the laboratory.

The sound is unique and singular, with the coldness and sharpness of a machine and the warmth and rhythm of a creature.

It is like an electronically synthesized sound wave, transmitted through the data pipeline, becoming deeper and more textured.

Bazin immediately pointed his two guns at the glassware that made a sound, and the sound of his gnashing of teeth rang out.

"Damn the aliens, it's you! It was the people who caused the [Palm Tree Man-made Base] to be directly destroyed, and everyone in the base was directly buried at the bottom of the sea!! ”

At this moment, Bazin, who found the real culprit who destroyed the artificial base, seemed so angry, but he was not completely carried away by the anger, as can be seen from the fact that he only drew his gun and shouted angrily instead of directly pulling out his gun and shooting.

Xia Xiu saw that Bazin's sanity was still there, and he didn't interfere too much, they finally found the real clue of the [Fog Sea Country Incident], and naturally they couldn't directly collapse the other party without getting any information.

[·······, it seems that the message of our distress signal was still captured by those guys, and they did use our distress signal as bait as Tupedro speculated, I am very sorry here, but we do not regret it.

For us, we want to get detailed information as soon as possible in the face of those abominable and unknown creatures, and deconstruction and analysis is the best option, and deconstructing and analyzing those beings always requires some sacrifice-]

“…… So you guys have killed my kind lightly for this. ”

Bazin's eyes were covered in frost at the moment, and the fourth sword-wielder of the Heavenly Kingdom on the side seriously began to look at the alien named [Miguel Set] on the vessel full of nutrient solution.

The creature that made noises that were neither human nor entirely machine was lying quietly in the largest circular biological storage vessel.

Somewhere between a snake and a fish, Miguel Set is about one to three meters long, with a slender and streamlined body that exhibits the elegance of an aquatic animal. Most strikingly, the creature's body is almost completely transparent, and its delicate muscle textures and slow-flowing blood can only be faintly seen when the light hits at a specific angle.

Its head is elongated, its eyes bright and sharp, and it seems to be alert to its surroundings.

It is now in a weakened state, but it can still feel the vitality and wisdom that lies within it.

The surface of the strange creature's skin is inserted with several glowing data pipes, which are tightly connected to its body, emitting a faint fluorescence.

The creature in the vessel contrasts sharply with the data pipes attached to it, and the data fluorescence that bubbles from the pipes creates an eerie beauty with the transparency and softness of the creature itself.

[Rest assured, we will no longer pose any threat to humans or even other creatures-]

The living [Miguel Set] seemed to sense Bazin's killing intent and spoke out in relief.

"You're going to die." Xia Xiu, who was originally silent, suddenly spoke up at this moment, he looked at [Miguel Set] who was inserted into his body by countless data tubes and said such an unlucky sentence.

[Your gaze is very vicious, yes, I, our race is about to be completely wiped out, I am the last survivor of [Miguel Set], my name is Galilei. This is the human name Pedro gave me, because we didn't need a symbol like a name to distinguish individuals, but Pedro is a rebel to the group like me, so I deserve a name, and now, as the last individual of [Miguel Set], I'm about to die—"

The alien race named Galilei calmly announced his death to the two humans at this moment.

Today was a wonderful day: the plane was supposed to depart at 2 o'clock, but I arrived at the airport at 10 o'clock, and then I was alone in a place at the airport with a computer and writing alone.

I finally got off the plane and took the subway.

I actually encountered a canon within a canon that can only appear on the Internet.

In the same car of the subway, two children were shouting in front, and one of the eldest brothers couldn't help but say: "Whose children, come out and take care of them." ”

Then the child's mother came out and said, "Are you childless?" What's wrong with the kids. ”

Because it's so classic, I and the people in the same carriage are really a bit Bengbu, I want to laugh, but I feel that the occasion is wrong, and I was holding the suitcase and shivering, I can't laugh!

The eldest brother was also very fierce, and replied directly: "It's because of parents like you that the social atmosphere is not good now." ”

The child's mother replied: "Do you have any quality, what's wrong with the child's play, you deserve to be single!" “

“······“ The eldest brother was silent for a while, then got up and said, "Stinky SB, you have quality!"

The child's mother was also angry, "You unqualified guy, if it weren't for the child here, we wouldn't be done on the spot now, are you not convinced now, call the police directly if you are not convinced!" ”

"Big SB, let me tell you, I don't care about you, what kind of children there are, what kind of parents there are, SB, I won't play with you."

The child's mother still wanted to say something, but the eldest brother had already left with his bag and went to the next box.
