Chapter 2802: ‘Breaking the Wall’ Effect

Zheng Qing couldn't use his own talisman gun and talisman bullet to hit his own clone's forehead.

But he was also very interested in this kind of low-dimensional interference with high-dimensional magic, and the professor of this class happened to be one of the few wizards who could answer this question.

Like the other two courses on Saturday afternoon - the principle of convergence and the Albus conjecture - the professor of the Dimensional School Introduction course also came from the relevant department.

Therefore, this professor knew more about a student with a special identity in the class.

After hearing Zheng Qing's question, he looked at the young wizard meaningfully, but did not speak directly. Instead, he walked down the podium, came to the wall, clenched his fist, and knocked it in the middle of the wall.

The action was quick and neat.

Crack!

The whole classroom was stunned by this punch.

A small dot suddenly appeared on the white wall. With the point where he landed his fist as the center, spider-web-like cracks spread rapidly around, and an ominous cracking sound came from the wall, as if the house would collapse in the next second.

Zheng Qing, who was just daydreaming, was stunned.

The performance of the other seniors was not much better than his. Everyone was speechless and stood up subconsciously. Some moved towards the door of the classroom, some held the table and seemed to be hesitant about whether to get under the table, and some half raised their arms, as if they were hesitating whether to ask the professor what happened.

A group of elves in gray robes rushed in in a hurry, but saw the wizard standing in front of the wall waving his back to them.

"It's all teaching arrangements, go down."

The professor's tone was relaxed, as if he had not smashed the wall of the classroom just now, but just killed a mosquito - but this "normal" attitude also made the classmates in the class quietly relieved - while speaking, the professor also turned a chair next to him into a yellow lion and threw it out of the door.

The elves hesitated, looked at each other, and finally left the classroom honestly.

The voices of the yellow lion, the school worker, and other students were faintly heard in the corridor, but in the end no one entered the classroom again to check what happened.

Soon.

The professor, who had been busy standing in front of the wall for a while, turned around and revealed his "masterpiece" behind him - he drew a picture on the snow-white wall, describing a mountain that was slowly collapsing after being hit by a giant's wooden stick. The place where the punch just hit was exactly where the wooden stick and the mountain touched, which was the core of the collapse.

In the whole painting, the giant, the wooden stick, the mountain, etc., all the pictures are on the wall, with only length and width.

Only those cracks of collapse have a real "height".

"Do you understand?"

The professor's eyes slid over the students one by one. Seeing that everyone was thinking, he nodded slightly. Without waiting for anyone to speak, he explained to himself: "... Just like what I have repeatedly emphasized in this class - 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 "dimensionality reduction".

Dimensionality reduction is the simplest and most straightforward way for low-dimensional to understand high-dimensional.

Just now, a classmate asked about the interference effect of low-dimensional on high-dimensional. I want to show you this painting. You can easily substitute this painting into a two-dimensional world, so everything in the painting should be two-dimensional in theory. But my punch..."

His finger pointed at the center of the fist mark.

Knocked.

"——This punch gave the painting a 'height' it never had before, and made the war in this two-dimensional world produce a 'wall-breaking' effect, as if it broke through the constraints of the law and took effect in a higher dimension. Similarly, I can smear a trace of real giant blood on this giant, or embed an obsidian in the place where the mountain collapsed, which will make the aftermath of the war that originally took place in the two-dimensional world spread to the three-dimensional world."

"And this is my first answer to the question that Zheng Qing just asked." The professor walked back to the podium slowly, picked up the pen and wrote a big "one": "... If the low-dimensional world wants to leave a trace in the high-dimensional world, it must be through the 'high-dimensional' way. Otherwise, just like that painting, no matter how three-dimensional the pattern you leave on the canvas is, it is ultimately just a visual illusion, just a 'illusion'... We can say that illusion is an effective way to understand higher dimensions, but we must never confuse the distance between illusion and reality."

Just like the blood rune bullet.

Zheng Qing muttered silently in his heart, and suddenly became a little curious about his current state. In theory, he was just a genuine low-level wizard, but on the other hand, he had many "high-dimensional characteristics".

He turned his head again and took a look at the painting on the wall.

"- But on the other hand, the influence of the high-dimensional world on the low-dimensional world is indeed uncontrollable!"

On the podium, the professor raised his voice slightly and emphasized his tone. Zheng Qing quickly moved his sight back, but saw that the professor had picked up a piece of mulberry paper and was showing it to the left and right. When he saw 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 to replace it - without considering resistance, it will naturally spread. If the paper is infinitely thin, until there is no height, and it becomes a real two-dimensional, then the drop of water will also spread infinitely until it fills the entire two-dimensional world.

In layman's terms, this is a "dimensionality reduction attack".

A little existence or concept in the high-dimensional world falls into a low-dimensional world. After it collapses, the disintegrated energy will fill the entire low-dimensional world. From the perspective of the two-dimensional world, it is roughly equivalent to a certain point in the world suddenly bursting out with incredibly huge energy, releasing matter 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 piece of 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 your unintentional move will destroy a world."

Zheng Qing's mind flashed back to the red light of the nearly melting two-dimensional evolution laboratory during the freshman school hunting game, the figure of Chromatrano flying away in the night, vomiting blood, and the figure of Chromatrano, who was vomiting blood and flying away in the night. A picture of the inner city of the Black Prison cut open by pillars.

He sighed slightly.

He rubbed his ears vigorously.

The small green dragon hanging on his ear was allowed to be kneaded without saying a word.
