From any angle of the pattern space composed of geometric lines, you can see different world forms.
The three-dimensional world that ordinary people are accustomed to is here just a point among these geometric lines.
Points and lines combine to form large and small geometric figures.
From a certain angle, these figures appear to be cubes, but from another angle, the shapes of the figures are completely different.
In this pale and empty place, all the geometric lines are silver-gray, shining with a faint silver light, just like the crisscrossing infrared rays seen through infrared night vision goggles in the dark night.
Lu Jin's heart moved, and he suddenly turned off the special function of the special glasses he was wearing.
Sure enough, he could no longer see the geometric lines spreading throughout the space, only nothingness.
He then turned on the switch of the special glasses, and those geometric lines appeared again.
It turns out that these geometric lines are invisible to the naked eye!
However, Lu Jian's special glasses simulated the imaging function of the human eye, but because they had to be recorded and broadcast, his glasses also had a mechanical imaging function.
In this case, he can see the ultimate simulation state of this game.
It seems that this AI is really capable.
Lu Jin seriously corrected his attitude.
Mathematics is the basis of all sciences.
The more advanced the subject, the more ubiquitous the importance of mathematics.
Lu Jin tried to take a few steps inside.
As soon as he moved, the crisscrossing geometric lines around him changed again.
It was like he was walking in a kaleidoscope of black and white structure. Every step he took could be reflected in the black and white mirror image here. However, with every step he took, the geometric lines around him were different from before.
It's like a permutation of a sequence of numbers.
His actions are vectors of change.
Every step he takes not only represents changes in length, width, and height, but also changes in time and space.
The fourth dimension beyond the three-dimensional space, from a mathematical concept, is not just time.
Lu Jin looked at everything in front of him and said to himself: "Would it be easier if we used analytic geometry to describe the four-dimensional space?"
"The three-dimensional space we are used to, length, width, and height can be regarded as the three coordinate axes in analytical geometry, the X-axis, the Y-axis, and the Z-axis. These three coordinate axes are orthogonal to each other, that is, they are at right angles to each other. .This is three-dimensional space."
After Lu Jin finished speaking, he took a step forward. The geometric lines on the screen froze for a moment, and then quickly formed a new shape.
He looked up at the new geometric figure in front of him, was silent for a while, and said, "The fourth dimension is an extra line on these three coordinate axes. We can call it the W axis."
"This extra line, the W-axis, may be time, space, or even any dimension we don't know."
"Its appearance allows us to have another direction perpendicular to the space we are accustomed to in addition to length, width and height."
"To put it figuratively, it's like a box appears on the computer screen with a cat inside. When we operate the computer and look down at the cat in the box from above, we are looking at the three-dimensional space from a four-dimensional space. space."
"We can do anything to the cat in the box."
"What's happening now is these gamers are the cat in the box. Who is looking down at these cats in the box from above, from outside the computer?"
Lu Jin frowned, stretched out his hand, and fiddled with the geometric lines.
If you don't wear his special glasses and look at it directly with the naked eye, you will find his actions a bit ridiculous, as if he is playing the harp in the air, with a mechanical beauty.
"...If this is the case, from a mathematical perspective, it is impossible for people who enter this game to find the players who were trapped in it before."
Lu Jin came to a conclusion.
As if to verify his conclusion, he clicked twice and pulled out the game's control panel.
The sweet female voice of Apple Siri that everyone is very familiar with sounded again.
"Hello, player No. XXXXXXXXXXXXXXXXXX, what can I do for you?"
Lu Jin remained silent and selected several parameters from the control panel.
"Time: XXXX, month XX, XXXX."
"Location: XXXX."
"NPC character: Song Haichuan."
Once these parameters are determined, the female Apple Siri voice will change.
"Sorry, the parameters you selected are invalid, please select again."
Lu Jin changed a few more time and location parameters, but without exception, they were all confirmed by the female voice.
"The player was judged to be a malicious attack by the system and was temporarily blocked. The block will be lifted after three days. Welcome back."
After saying that, the geometric lines in front of Lu Jin's eyes started to rotate rapidly, then shrunk smaller and smaller, like thousands of pixels on an LCD TV screen, and finally disappeared.
Lu Jin was kicked out of the game system.
He took off his helmet and said seriously: "I have to review advanced mathematics."
Lu Yuan, Song Jinning, Huo Shaoheng: "..."
Lu Jin pretended not to see their petrified faces and said, "The mathematical foundation of this game is very solid, so it can withstand ever-changing variables."
When passing Song Jinning, Lu Jin stopped and asked curiously: "Director Song, were your father's math scores good back then?"
Song Jinning nodded blankly, "My father's undergraduate major was mathematics. He was the gold medal winner of the International Mathematical Olympiad at the age of fourteen."
"No wonder..." Lu Jin murmured, "I want to use mathematics to analyze the twenty-five lines of source code."
He said and walked out the door.
Song Jinning was a little anxious. He looked at Lu Jin's back with obscure eyes, stopped him and said, "General on the road, what should I do about Nian Zhi? Don't you give it a try?"
Lu Jin stopped, looked back at him, sighed, and said, "It's useless to be anxious. The opponent is too high, I have to think about it."
"But it has released game rules and launched grand prizes so that the direct blood relatives of the 50 million players can enter the game to find their relatives. Doesn't this count?"
Song Jinning was very puzzled.
Lu Yuan and Huo Shaoheng were both involved in conspiracies and conspiracies. They understood the AI completely as a human being, so there was nothing uncomfortable about it.
"Ms. Song, people can lie, and so can AI." Huo Shaoheng said unhurriedly, and the round gold coin in his hand fell on the table with a thud.
He reached out and clasped it, stood up, and said calmly: "...I'm going to the Cayman Islands to go there myself."
"What are you doing there? This artificial intelligence has already controlled the entire network, and it doesn't matter to them where you are." Lu Jin shook his head, "Don't do useless work."
"Control the entire network?" Lu Yuan felt that Lu Jian was exaggerating a bit, "Isn't that true?"
"Why not?" Lu Jin almost sneered, "Look, it can filter out the most direct blood relatives of the 50 million players before they can log in to the game. How do you think it does it?!"
"How is it done?" Song Jinning was also curious, "Could it be able to detect DNA quickly?"
"Wrong! It doesn't need to detect DNA by itself!" Lu Jin looked at the gaming helmet on the table, "It relies on big data!"
"With hundreds of millions of players and several years of operation, it has already mastered all aspects of big data!"
"Who you are, where you are, and what you've done, it's all clear!"
"It is as normal for AI to deduce what you are going to do next from this information as it is for humans to eat, drink, and sleep!"
"... But even if there is big data, it knows who the most direct blood relatives of the 50 million players are, but how can it determine that the people who log in are those most direct blood relatives?" Lu Yuan thought that the problem was the most practical and focused on operability. .
Lu Jin rolled his eyes, then pointed to his own eyes, "iris. That gaming helmet determines identity by scanning the iris of a person's eyes. - Do you know what real-name authentication is? This is its real-name authentication!"
Huo Shaoheng's expression changed and he said seriously: "So, it has already invaded the database systems of governments and hospitals at all levels?!"
"Theoretically, it should be able to reach the point where it is now." Lu Jin shrugged, "But our sample bank is too small, so we can't draw this conclusion yet."
Song Jinning breathed a sigh of relief and said: "Statistically speaking, we only have one sample. We really need to expand the sample database to determine whether all government and hospital database systems around the world have been invaded by it."
Huo Shaoheng made a decision immediately: "I will first test our country's important database systems, and then send people to contact the officials of several big countries."
"Don't send any messages over the Internet." Lu Jin reminded him, "It's very likely that any messages you send will be monitored by it."
Huo Shaoheng nodded, "Yes, so I sent someone to contact you directly. I won't use the Internet to send messages or emails."
"... You're all gone, what should I do with Nianzhi?" Song Jinning felt very depressed when he thought of Gu Nianzhi lying unconscious in the bedroom.
"What they are doing is to save Nianzhi." Lu Yuan comforted Song Jinning softly, "If a worker wants to do his job well, he must first sharpen his tools. They are building their 'tools'."
Song Jinning knew this, but she still felt a little uncomfortable and murmured: "It would be great if I could go in..."
She can't even go in now even if she wants to.
In the following time, Lu Jin began to study advanced mathematics sleeplessly.
Huo Shaoheng also finally determined that the Chinese Empire's government systems and the databases of various hospitals and commercial institutions had been invaded to varying degrees by unknown external systems.
He was leading people to nervously assess the scope of the invasion and the extent of the damage.
However, what is certain is that the central control system of their Special Operations Department has not been hacked, nor have the empire's most confidential databases.
Just when their progress was at a stalemate, exciting news continued to come from the Internet.
"Someone logged into the Second Life game and found their loved ones in it!"
"Someone has woken up! Their family also won the first grand prize!"
"Did you know? The grand prize in that game is more than one million!"
"The first person to eat the crab succeeded, and their family won the highest prize - a grand prize of 10 million US dollars!"
"I'm so envious! My loved one has woken up, the game has been cleared, and the bonus has been obtained! - There is no better winner in life than this!"
