It was impossible for Zheng Qing to use his own talisman spear and talisman bullets to blast his clone's head.
But he is also very interested in this kind of magic problem of low-dimensional interference with high-dimensional things, and the professor of this class happens to be one of the few wizards who can answer this question.
Like the other two courses on Saturday afternoon - the principle of convergence and Albusto's conjecture - the professor of the course "Introduction to Dimensionalism" also comes from relevant departments.
Therefore, the professor knows more about a certain student with a special status in the class.
After hearing Zheng Qing's question, he gave the young wizard a meaningful look and did not speak directly. Instead, he walked off the podium, came to the wall, clenched his fist, and knocked on the center of the wall.
The movements are crisp and neat.
Click!
The whole classroom was stunned by this punch.
A small dot suddenly appeared on the white wall. Centered on the point where he dropped his fist, spider-like cracks quickly spread to all sides. An ominous clicking sound came from the wall, as if the house would collapse in the next second.
Zheng Qing, who was thinking wildly, was suddenly shocked and stunned.
The performance of several other seniors was not much better than him. Everyone was speechless and stood up subconsciously. Some people moved towards the door of the classroom, some people were holding on to the table as if hesitant to get under the table, and some people's arms
He half-moved, as if hesitating to ask the professor what happened.
A group of elves in gray robes rushed in, only to see the wizard standing in front of the wall waving to them with his back.
"It's all teaching arrangements, go down."
The professor's tone was relaxed, as if he had not smashed the classroom wall just now, but had just killed a mosquito - but this 'normal' attitude also made the classmates quietly breathe a sigh of relief - while speaking, the professor also touched his body
A nearby chair turned into a yellow-skinned lion and was thrown out the door.
The elves hesitated, looked at each other, and finally exited the classroom honestly.
The voices of yellow-skinned lions, school janitors, and other classmates were vaguely heard in the corridor, but in the end no one entered the classroom again to see what happened.
soon.
The professor, who had been busy for a moment in front of the wall, turned around and revealed the 'masterpiece' behind him - he drew a picture on the white wall, depicting a mountain peak that was slowly collapsing after being hit by a giant stick.
, the place where the punch just hit was exactly where the stick came into contact with the mountain, which was the core of the collapse.
In the whole painting, giants, wooden sticks, mountain peaks, etc., all are on the wall, only having length and width.
Only those collapsed cracks have a real ‘height’.
"Do you understand?"
The professor's eyes glanced over the students one by one. When he saw that everyone was thoughtful, he nodded slightly. Without waiting for anyone to speak, he explained to himself: "... Just like what I said in this class
The sentence repeatedly emphasized above - when we cannot handle an unknown concept, we might as well summarize this concept into a dimension - this process of induction can be understood as 'convergence' or as 'convergence'.
'Dimensionality reduction'.
Dimensionality reduction is the simplest and most straightforward way for low dimensions to understand high dimensions.
A classmate just asked about the interference effect of low dimensions on high dimensions. I want you to take a look at this painting. You can easily substitute this painting into a two-dimensional world, then everything in the painting should theoretically be
Two-dimensional. But my punch..."
His finger pointed at the center of the fist mark.
Knocked.
"——This punch gives this painting a 'height' that it never had, making the war in this two-dimensional world have a 'wall-breaking' effect, as if it broke through the shackles of the law and took effect in a higher dimension.
Similarly, I can rub a trace of real giant blood on this giant, or embed an obsidian in the place where the mountain collapsed, and the aftermath of the war that originally took place in the two-dimensional world will spread to the three-dimensional world.
"
"And this is my first answer to the question just asked by classmate Zheng Qing." The professor slowly walked back to the podium, picked up a pen and wrote a big '一': "...the low-dimensional world wants to be in the high-dimensional world
To leave traces, you must use a 'high-dimensional' method. Otherwise, just like that painting, no matter how three-dimensional the pattern you leave on the canvas is just a visual illusion, it is just an 'illusion'... We
It can be said that illusion is an effective way to understand higher dimensions, but the distance between illusion and reality must not be confused."
Like blood runes.
Zheng Qing muttered silently in his heart, suddenly curious about his current status. In theory, he was only a genuine low-level wizard, but on the other hand, he possessed many 'high-dimensional characteristics'.
He couldn't help but turn his head again and glanced at the painting on the wall.
"——But on the other hand, the impact of the high-dimensional world on the low-dimensional world is indeed uncontrollable!"
On the podium, the professor slightly raised his voice and emphasized his tone. Zheng Qing quickly looked away and saw that the professor had picked up a piece of mulberry paper and was showing it to the left and right. When the boy turned his head, he snapped his fingers.
A drop of ink appeared out of thin air, fell on the white paper, and spread quickly.
"...A drop of water in the three-dimensional world falls on the two-dimensional world - here we use a piece of paper instead - it will naturally spread without considering resistance. If the paper is infinitely thin, until it has no height, it will become a real
two-dimensional, then the drop of water will spread infinitely until it fills the entire two-dimensional world.
To understand it in layman’s terms, this is a ‘dimensionality reduction strike’.
A point of existence or concept in the high-dimensional world falls into the low-dimensional world. After the collapse, the energy of the collapse will fill the entire low-dimensional world. From the perspective of the two-dimensional world, it is roughly equivalent to a sudden explosion of order from a certain point in the world.
Man’s unbelievably huge energy releases material that can fill the entire world…”
Zheng Qing subconsciously thought of the 'Big Bang Theory' that he had learned in high school. The drop of water that the professor just dropped on the paper looked like the 'pole' in the Big Bang Theory.
"——This is the uncontrollability of cross-dimensional influence." The professor crumpled the paper stained by a ball of ink, threw it into the trash can, glanced at Zheng Qing, and said seriously: "So, I said so much
, I want to remind you not to aim too high and easily touch the power that you cannot control. Otherwise, it is very likely that one of your unintentional actions will destroy a world."
Zheng Qing's mind flashed back to the red light of the almost melting two-dimensional evolution laboratory during the freshman school hunting game, flashed to the figure of Chromano flying away in the night, vomiting blood, and flashed to the scene of a slender red rod
A picture of the inner city of the Black Prison cut through columns.
He sighed slightly.
He rubbed his ears vigorously.
The little green dragon hanging on his ear was allowed to be kneaded without saying a word.
