Everyone gathered around the Portkey and reached out a finger to touch the Quaffle.
It was time to go, they were waiting in silence.
Mr. Weasley pulled out his pocket watch, staring at the time with one eye and whispering, "Three...two...one!"
As soon as his voice dropped, they began to spin rapidly.
Under the pull of the Portkey, they were spinning, their feet leaving the ground and flying through the air.
This time, with no curse holding him down, Ivan was much more sensitive to the magical fluctuation around him.
The scene around them began to fade.
The next second, Ivan did not reach his destination directly, but entered a strange space.
Everything he perceived seemed to be composed entirely of magic, and colored lights twisted around him.
Ivan had an inexplicable strange feeling. This place, this space had a strange familiarity.
Harry, Hermione, Sirius and everyone else disappeared. Only Ivan was here alone.
Looking around, he soon remembered that it was very similar to his previous experience in the ruins of the fallen centaurs, where his soul was pulled into an eerie fantastical space.
Although the surrounding landscape was different, the two places seemed to be of the same nature.
No doubt, Ivan still remembered the sky he had seen at that moment, exactly like that.
There, all the colors and objects were twisted, and distance, time and space seemed to have lost meaning.
In Muggle physics theory, there is the concept of "High Dimensional Space".
Unlike the real world where humans live by three-dimensional space and time, high-dimensional space is more advanced.
It could be somewhat envisioned by the example of a tiger drawn on a piece of paper. If you want to catch it, draw a circle around the tiger on the paper.
The tiger on the paper cannot get out of its interior because it exists only in two-dimensional space.
By analogy, by adding a third dimension of height, the tiger has a way out.
In that case, a real cage would need to trap it, and the two-dimensional cage would have no effect.
In terms of dimensions, 3D is obviously more advanced than 2D.
The three dimensions are combined, which is the limit that humans can perceive.
The fourth dimension is time, which is a higher dimension.
Although humans cannot perceive it, time is always affecting all beings, and it is tracked by clocks.
Using time-turners, magicians can move between different times.
But because this dimension is more advanced, the whole process of moving is extremely dangerous, to the point that it is considered taboo.
Ivan once returned to Hogwarts a thousand years ago, which was already very, very deep magic.
He didn't feel much at first, but the more he learned about the time, the more he realized this.
How amazing it was to have that experience two years ago!
Perhaps only high level wizards of the level of the Four Founders of Hogwarts could use that kind of magic.
Of course, time, that is, the fourth dimension, is not the end of everything.
Moving upwards, there are still higher dimensions.
There, the lower dimensions, either space or time that humans are familiar with, will lose their meaning.
Just like a real tiger and a tiger on paper, the tiger on paper is naturally lower.
For everyone, it is just a picture.
Intelligent creatures living in high-dimensional space will also feel this way when they look at humans living in low-dimensional space.
The more advanced the dimension, the more difficult it is to describe in words.
But with the activation of the Portkey, Ivan now entered this different space; he entered a higher dimension.
He looked around curiously, and an absurd idea suddenly appeared in his mind.
Here, his normal senses were not functioning at all, because this was beyond the limits of his body's perception.
For others, whether they used Apparition or Portkeys, there would be a short blank in his memory.
Blank space occurs in this different space because they cannot perceive it.
With Ivan it was different. Maybe it was because he was once taken to a different space by the evil god of the centaurs, or maybe because he was now becoming more sensitive to magical fluctuation, no matter what it was, Ivan was now able to clearly see everything around him.
Not with his eyes, but directly through his soul; he was using his soul to feel. He was not lost like everyone else. He just felt a flash in his eyes and reached his destination.
With his soul, Ivan could clearly get a panoramic view of this different space.
There was no doubt that this place did not belong to the real world, but it existed.
A strange thought came to Ivan's mind. He remembered the place where the evil gods said they were born.
The ancient sorcerers once entered it, and apparently it did not belong to the real world, otherwise the evil spirits would have destroyed the world long ago.
Perhaps they existed in a very high-dimensional heterogeneous space, like the different space that wizards had to enter every time they appeared and used Portkey.
Compared to all magical creatures, the power and existence of evil spirits were obviously more advanced.
And most of them and the forms of monsters they created were indescribable.
This was because they were creatures that existed in high latitudes and could not be represented in low dimensions.
Incidentally, Slytherin left a slate map of the temple where the lair of Herpo the Mad was located.
Ivan originally thought it was ancient Greece, but he and Hermione compared carefully, and that place did not exist in the real world.
Following this line of thinking and reasoning, there could be many different spaces than ours.
As the most evil dark wizard in history, Herpo the Mad had probably managed to transform his body into an evil god.
This gave him the ability to use certain abilities of these evil spirits, such as entering a dream, acting directly on the mind and so on.
If so, he could also have the ability to cross different spaces like a real evil god.
What might be more difficult to handle, is that the Temple he had built could be in a very different space.
This was unbelievable at first, but the pieces of the puzzle seemed to be falling into place, and an amazing model of what the truth might be gradually built up in Ivan's mind.
A wider door to the world of magic slowly opened before his eyes.
He felt his purpose becoming clearer and clearer, and evil spirits were coming into the world, that is, from this space different from the real world. In addition to needing enough flesh and blood, they also needed a large supply of Philosopher's Stone magic.
Whether it was the Philosopher's Stone or the evil god, they all appeared in the Book of Abraham.
This was the only magical book known to have been preserved by the ancient sorcerers of the world.
It was the only way to understand the wizards who once had the power to destroy heaven and earth, and many magical spells.
Thousands of years ago, they had entered the space where the evil spirits were. Perhaps this was the clue they left behind for future generations.
