After demonstrating how to form Raggadorr Rings using energy projection, Wong then began to demonstrate how to open a Dimension Door.
Energy projection and Dimension Door are among Kamar-Taj's core magical abilities, and are primary spells that all Kamar-Taj sorcerers should learn, from which multiple uses are extended.
Wong extended his left hand, wearing a sling ring, forward, with his index and middle fingers together, and began to draw a circle with his right hand.
"Still, the sling ring is very important. It not only helps us cast spells but also helps us travel freely to all corners of the universe."
Sparks gradually appeared.
"When opening a Dimension Door, you must concentrate your mental power, and your destination must appear in your mind. You need to recall the details of your desired destination in your mind. The clearer the image in your mind, the faster the Dimension Door will appear."
Wong's right hand's rotation speed didn't change, but the portal formed by the sparks spun faster and faster.
Suddenly, the portal opened, and a biting cold wind accompanied by a blizzard blew from the Dimension Door into the spacious training room. The sudden cold made Chen Yu sneeze.
Wong was the same, frozen by the sudden cold wind. He did not close the Dimension Door but endured to let Chen Yu see the scenery on the other side.
Through the Dimension Door, Chen Yu saw a vast expanse of white on the other side. Looking into the distance, there seemed to be a towering snow mountain.
The strong wind howled, and the biting cold wind rattled everything in the room.
Chen Yu could only shout to Wong, "Wong, where did you open the Dimension Door?"
Wong also shouted back, "I opened the Dimension Door on Mount Everest!"
"Close the Dimension Door, I've seen the effect, it's too cold!"
"Okay!"
Wong still responded loudly.
As Wong responded, the portal made of sparks in front of them suddenly shrank and disappeared.
"Oh~~~, it's so cold..."
After closing the portal, Wong quickly stood up, wrapped his clothes tightly around himself, and vigorously rubbed his hands together.
Just this gust of wind dropped the room's temperature by at least 10 degrees.
Chen Yu used his wand to relight the brazier that had been extinguished by the cold wind, looking at Wong with dissatisfaction.
"Of all the places you could open the Dimension Door, you had to open it on Mount Everest, looking for a freeze!"
Wong leaned closer to the lit brazier, tossed the sling ring to Chen Yu, and quickly rubbed his hands together, explaining, "Sorry, this is all due to habit. Every year, there are sorcerer apprentices who can't master the magic of opening a Dimension Door. To help them break through in extreme situations, we throw them onto Mount Everest and tell them that a person will go into shock in two minutes under such extreme conditions. Under the pressure of survival, most sorcerer apprentices can successfully cast the Dimension Door."
"If they fail, it doesn't matter, because a person can survive for 30 minutes in that situation. As long as we calculate the time and they don't run around, we can rescue them."
"But if a sorcerer apprentice fails to successfully open a Dimension Door even in such a harsh environment, it means he truly has no talent for being a sorcerer. In such cases, we will ask him to go down the mountain and no longer let him waste time at Kamar-Taj."
"Since you already possess your own magic, you can start practicing with the sling ring now. I'll just watch from the side."
After Wong finished speaking, he continued to warm himself by the fire.
Chen Yu put the sling ring on his left hand.
Sharpening the axe does not delay chopping wood. Chen Yu did not immediately start practicing the Dimension Door magic but first applied a learning buff to himself with Merlin's Ring.
Seeing the magic circle appear at Chen Yu's feet, Wong knew that Chen Yu was once again using the wondrous magic from his world.
Wong saw the six letters appearing in the inner ring of Merlin's Ring and began to murmur, "These symbols are Rune, could it be magic passed down from the Asgardian realm in another world? Hmm... learning, thinking, concentration, activity, acceleration, clarity... It seems to be magic specifically for aiding learning."
As expected of the Kamar-Taj Librarian, he could discern the meaning of these Rune and largely guess their effects at a glance.
Chen Yu stood in the center of Merlin's Ring, with his left index and middle fingers together, and began to draw a circle with his right hand, imagining himself in the Kamar-Taj lounge.
He didn't plan to open the portal to the restaurant where Ancient One had brought him, as Tony and Dr. Yinsen had already left that city, so it didn't matter if he went there or not.
Using Merlin's Ring, Chen Yu's mind was more easily focused, and his thoughts were more active. He felt that the mental intention required to open Kamar-Taj's Dimension Door was very similar to that required for Apparition.
Chen Yu remembered that the books recorded three important principles to remember when practicing Apparition: destination, determination, and deliberation.
First step: Focus your attention on your destination, that is, think about the place you want to go.
Second step: Occupy the space you are thinking of with determination! Let the desire to reach your destination overwhelm every smallest part of your body!
Third step: Spin in place, allowing yourself to enter a state of void. The movement should be deliberate, and you will arrive at your destination.
If the will to go to the desired place in your mind is not firm, a phenomenon of splitting will occur.
And when practicing Dimension Door magic, a similar mental intention is required.
The sorcerer needs to concentrate his mental power, and his desired destination must also appear in his mind.
If he learned Kamar-Taj's Dimension Door, he should be able to try practicing Apparition.
Despite being different worlds, casting magic requires similar emotions and steps.
Is this the magic of different paths leading to the same destination?
Chen Yu thought while drawing circles.
This was the advantage of practicing Dimension Door; even if he was distracted, he didn't have to worry about the terrifying phenomenon of splitting.
A golden spark appeared in front of Chen Yu, then began to spin.
Seeing the sparks appear, Chen Yu quickly cleared his mind of distracting thoughts.
As the image Chen Yu imagined in his mind became clearer and clearer, the portal in front of him rapidly expanded.
Soon, a Dimension Door with a diameter of about 1.7 meters opened in front of Chen Yu.
At the same time, a system prompt sounded in his ear.
"【Congratulations to the player for learning Kamar-Taj's Dimension Door magic】"
Chen Yu looked at the room layout on the other side of the portal; it was indeed the room where he had rested last night.
Just as Chen Yu was about to step through, Wong reminded him from the side, "Opening a Dimension Door with a sling ring is actually using mental power and magic to carve a tiny, temporary wormhole in three-dimensional space. Pay attention to the sparks around the Dimension Door; those sparks are materialized spatial debris. When you step through, never step on the sparks. If you don't want to experience your body being cut by space, always be mindful of these when passing through the Dimension Door."
"Really?"
Chen Yu took it somewhat seriously.
"Fake, as long as you pass through before the Dimension Door closes, you'll be fine."
Wong smiled, obviously finding it amusing to tease Chen Yu.
Chen Yu rolled his eyes at Wong, not expecting him to have the presence of mind to joke with him.
Stepping through the Dimension Door, he arrived in the room where he had rested last night.
Chen Yu was still somewhat excited to have mastered this magic.
Learning this magic would make it much easier for him to buy or sell things in Diagon Alley in the future.
The Dimension Door is magic from this world; there is no corresponding counter-spell in the world of "Harry Potter."
This means that the anti-Apparition charms set up against wizards in Hogwarts School would be ineffective against the Dimension Door magic Chen Yu now wielded.
Similarly, in this world, there should also be no specifically developed counter-spell against Apparition.
With this ability to open a Dimension Door, he could easily enter Hogwarts School.
He could leave school whenever he wanted, and return to school whenever he wanted, all without anyone knowing.
This method of skipping classes would be the dream of how many students.
