The number above is very interesting and self-describing.

In other words, these numbers are self-describing.

There is a saying circulating in Terran academia: "If I had only one hour to save Terra, I would spend fifty-five minutes defining the problem and only five minutes finding a solution."

A qualified academic researcher attaches great importance to problem-solving methodologies, especially the importance of defining problems and accurately understanding them.

And this sentence is especially applicable to all thaumaturges in Terra today.

In today's Terra, genealogy network, think tanks and pan-AI are fully proliferating: asking questions and how to ask questions better will be more important than how to solve problems quickly and conveniently.

In the field of thaumaturgy, the explosion of genealogical productivity has exceeded personal imagination.

The raising of problems is more important than the solution of problems. This is the innovation brought about by technology.

Therefore, to understand the meaning of the numbers on the door, the first thing is of course to define it.

The above numbers can be understood as: "self-describing numbers".

A self-describing number, as the name suggests, is a number that can describe the characteristics of the number itself through the number itself.

To summarize this characteristic of describing itself through the numbers themselves in one sentence, that is: the number on each digit in this number is the number of times the value of that digit appears. (The digits start from 0, from left to

Right and so on)

Xia Xiu was keenly aware of the characteristics of the numbers above. Each single digit of these numbers can accurately describe the characteristics of the number itself. More specifically, in a self-describing number, the number on each digit represents the number.

The number of times a digit appears in the number.

For example, this set of numbers: 1210

The number in position 0 is 1, which means that the number 0 appears once in the entire number.

The number in position 1 is 2, which means the number 1 appears twice in the entire number.

The number in the second position is 1, which means that the number 2 appears once in the entire number.

The number in the third position is 0, which means that the number 3 appears 0 times in the entire number.

The number in the 0th digit = 1, so 0 appears only once (“1” 210); the number in the 1st digit = 2, so the number 1 appears twice (1 “2” 10), and so on.

The number in the 2nd digit is 1, so 2 only appears once (12 "1" 0), and the number in the 3rd digit is 0, so it means that its occurrence in the integer number is 0.

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

Therefore, the filling of numbers on [Vitruvian Door] must now conform to the characteristics of self-describing numbers. The number displayed on the number lock slot above is: 32████0.

The number in the 0th position is 3, which means that this set of numbers will have three 0s, and a "0" has been seen on the door leaf, so there are still two positions with "0"s.

The number in the first digit is 2, which means that this group of numbers will have two 1's.

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

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

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

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

The remaining positions can now be analyzed directly:

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

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

"4" and "5" won't appear since there can't be four or five digits 4 or 5 in this number.

So, there is only one answer!

The blackened part can only be "1100" because it meets all the conditions.

So the complete number is "3211000".

After deducing the answer, Xia Xiu immediately started turning the digital lock on the [Vitruvian Door].

The above-mentioned inference process is placed on a macroscopic time scale, not even a minute has passed, so Xia Xiu's sudden rotation of the number slot has frightened a certain legendary hunter who was staring at the portrait of [[Vitruvian Man] with all his attention.

"What are you doing!?"

Bazin, who had been concentrating on observing the door, heard the sound and turned around to stare.

Then, his face was filled with panic.

He stared at the fourth sword holder in the Kingdom of Heaven with a surprised look on his face, his eyes fixed on the swinging door in front of him.

Under Bazin's gaze, the blond young man's fingers slid lightly on the number slots. He seemed not to be afraid of this seemingly difficult mystery at all.

With each turn, a number was accurately positioned on the space, gradually forming a four-digit number. The blond young man operated so quickly and confidently, as if he already knew the password.

The reason Bazin panicked was because there were only three attempts for this number lock.

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

For Bazan now, the clues and truth about the Country of Mist Sea are more important than his life.

The man-made island was destroyed by giant ocean beasts. One by one, his companions were invaded and corroded, and died miserably in front of him. The people he was supposed to protect died in a foreign land, but he "survive".

Since he survived, he must seek justice for all the people who died.

Facing Bazin's surprise,

The blond young man's expression remained calm, as if he was convinced of his judgment.

After entering the last number, he gently pressed the confirm button.

Bazin held his breath and waited nervously for the results.

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

This chapter is not over yet, please click on the next page to continue reading the exciting content! Bazin had an expression of disbelief on his face, he could hardly believe what he was seeing.

The blond young man turned his head and showed a smile to Bazin. He stretched out the index finger of his right hand and tapped his temple lightly, and said with a smile:

"Please, angels in heaven are not fools. We all rely on our brains to make a living."

"..." Bazin was speechless for a moment.

When this sentence came from the mouth of an angel from heaven, he felt uncomfortable hearing it, but now he couldn't refute it.

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

"Let's go, let's see what Pedro Miguelset is up to."

Xia Xiu pushed open the door and spoke to Bazan, who had not yet reacted. Then, he took the lead and stepped into the door.

Bazin immediately reacted from his daze. He saw the blond young man walking in first, and immediately took out his thaumaturgy handgun. After activating the pre-prepared thaumaturgy bombs, he followed suit and walked into the door.

*************

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

The light bulbs embedded in the walls of the laboratory flickered on and off, flashing unstable light, creating a strange and uneasy atmosphere in the laboratory.

The light casts long shadows with each flicker, making the entire space appear darker and more depressing.

Buzz——

A special door suddenly emerged from the void. Then, the door opened, and a handsome young man with blond hair and golden eyes walked out.

When Xia Xiu walked out of the [Vitruvian Door], his nose wrinkled subconsciously, and a unique smell filled the air.

The first thing you smell is a unique and pungent smell, which is the smell of formalin. This smell is mixed with other smells in the air, such as the slight cold metallic fragrance and the subtle smell of mechanical grease, which together form a

An impressive ambient atmosphere.

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

Under this flickering light, rows of round biological storage vessels are arranged, each vessel filled with clear green nutrient solution.

Floating quietly in these vessels is a strange creature.

Their bodies are slender, and their transparent skin becomes more obvious in the nutrient solution, and their delicate muscle texture and slow-flowing blood are vaguely visible.

Pipes emitting data fluorescence are inserted into the body surface of these creatures.

One end of the pipeline is connected to the complex equipment in the laboratory, and the other end is inserted deeply into the living body. These pipelines emit a faint blue light under the light, giving people a sense of the future where technology and life are intertwined.

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

【Tomb of Miguelset】

An unusually conspicuous word appeared at the top of the display.

Buzz——

Bazin's figure also appeared in this cold laboratory called [Tomb of Miguel Seth].

"Is this here?" Bazin held the [Ebony Wood] and [White Ivory] tightly in his hands, and his eyes were quickly attracted by the rows of strange utensils in the laboratory.

[Finally, finally, living Terran humans are here!]

[Thaumaturge gun, you are the hunter of [Hall of Hunting]!!!]

[Pedro’s rescue signal was finally successfully transmitted to Terra——]
