Chapter 493 Blueprints and Retractable Magic Lines

During the Triwizard Tournament, Roger was thinking about suitable means of transportation. The elegant carriage of Beauxbatons, the mysterious black ship of Durmstrang, and the iconic express train of Hogwarts.

Yes, it was the steam train that carried students between King's Cross Station and Hogwarts when they were on vacation or when school started.

It is not limited to that fixed line, but can also run on any rail in the world. Such ability undoubtedly made Roger's heart itch.

He opened a thick folder, and there were more than a dozen carefully designed sketches in it. There was the Jackdaw of Leap of Faith, the Diamond Storm Seer, the Nautilus of 20,000 Leagues Under the Sea, as well as the steampunk moving castle, the non-smoking high-speed train...

Roger leaned against the seat, and the expression on his face looked very embarrassed. Each design was full of creativity and dreams, making it difficult for him to make a decision.

For adults, of course I want them all, but who makes him not yet an adult. And time is running out, he must make a choice.

Just as he was lost in thought, his eyes accidentally fell on a yellowed photo. It was a flying machine with a huge streamlined body, with a small pod hanging below, the tail gradually shrinking, and with a protrusion similar to a fish fin.

Rogge's eyes lit up instantly, and he whispered its name: "Zeppelin airship."

This name, as if with extraordinary magic, made countless possibilities emerge in Rogge's mind.

As the most representative flying machine in the 20th century, it combines the beauty of retro and machinery, and has the shocking sense of giants and technology, which perfectly fits all the expectations in Rogge's heart.

He imagined himself riding such an airship, freely shuttling between the blue sky and white clouds, going wherever he wanted. The only regret is that the hydrogen in the airbag is a stable explosive that will speed up your heartbeat.

However, this risk factor is not an insurmountable problem for wizards. Just cast a floating spell to make it fly high and stable.

"That's it." Rogge said to himself, with determination and expectation flashing in his eyes.

He began to plan how to transform the airship to make it more suitable for his needs.

First, hollow out its belly and transform it into a luxurious cabin; then cut the curved top of the motorboat flat to make it look like the top of a cruise ship, so that you can enjoy the fun of flying and experience the feeling of sailing on the sea...

He quickly directed the feather pen to draw his ideas on the parchment one by one. As the feather pen danced, a design of a magic airship based on the Zeppelin airship gradually appeared in front of him.

It not only has the magnificent appearance of an airship, but also incorporates magical elements, making the entire design look both practical and full of fantasy.

The entire airship roughly maintains the classic appearance of the Zeppelin airship. From a distance, it looks like a Kun flying in the blue sky.

Its top is an irregular oval platform with a huge swimming pool and a diving platform as high as ten meters.

The second floor is designed as an ecological area, which will be equipped with a closed magical creature breeding house and an area dedicated to planting to provide fresh ingredients for the airship.

The third floor is a rest area with several well-equipped and luxuriously decorated bedrooms to ensure a comfortable rest environment during long journeys.

The fourth floor is divided into a research area, which is divided into four parts: potions, magic runes, casting and magic circles, providing a perfect laboratory for magic research.

The bottom floor is the cockpit, which is responsible for controlling the speed, altitude and attitude of the airship to ensure that the airship can fly safely and stably.

Rogge excitedly wrote down the specific uses of each floor, and planned to use a giant bubble head spell to increase the diving function of the airship, so that it can not only fly in the air, but also explore underwater.

He was so excited that he was busy designing the airship in the Defense Against the Dark Arts class and didn't hear Professor Lupin's class at all.

"... The bubble head spell is a very practical magic..." Lupin's eyes flashed with helplessness after learning from Harry that Snape mocked him.

Although he felt like he was dominated by Snape, he still introduced the three magics of armor protection, obstacles and bubble head spell to the students in detail.

Because as long as they can master them proficiently, students will have greater security when fighting against Death Eaters and magical creatures, and can even be said to be half Aurors.

"Rogge!" Lupin's voice rang out in the classroom, his eyes fixed on the student who was concentrating on his world on paper.

Rogge didn't notice that the surroundings had become quiet, and everyone's eyes were cast over him. His mind was all on his magic airship design, and the quill in his hand was flying on the parchment, outlining the shape of his dream.

Daphne kicked his stool gently from the back row, and this small action finally woke him up from his concentration.

"Hmm?" He raised his head and looked around with a confused face, and the innocent expression instantly triggered a burst of laughter.

Lupin didn't get angry, he said in a calm voice: "Mr. Rogge, please come up."

"Oh, professor." Rogge finally came back to his senses, and a bitter smile appeared at the corner of his mouth.

"You attack..." Lupin's initial idea was to show the spell himself, but he soon realized that Rogge's powerful magic might cause accidents, so he immediately changed his words, "I will attack you, and you can only use obstacles and armor to protect yourself."

"No problem." Rogge immediately expressed full cooperation.

"Everyone, pay attention. I will ask questions later."

As soon as he finished speaking, a wand suddenly appeared in Lupine's hand. Before anyone could see clearly, a dazzling red light flashed from the tip of the wand.

"Armor protection!" Rogge's eyes narrowed, and he quickly extended his palm forward. Use your wandless spellcasting skills to quickly block the professor's attacks.

The air in front of the palm was hit by the magic spell, and an invisible ripple appeared. Immediately afterwards, the red light reflected and hit the chandelier on the ceiling.

The chandelier made a loud noise and shook, and the students below hurriedly fled. They looked at the violently swinging lamp, completely forgetting Professor Luping's reminder just now.

"Look, it's Transfiguration!" Someone shouted, drawing everyone's attention back to the classroom.

Lupine remained silent, his wand passing through the air, leaving behind complex phantoms. The ink bottle on the table transformed in a magical light and turned into a burly giant wolf.

The giant wolf opened its mouth wide, kicked its limbs hard, drew a graceful arc in the air, and rushed towards Rogge.

In the face of this kind of physical attack, ordinary armor protection spells cannot effectively defend against it. Unless Rogge takes the initiative to increase the level of the spell and materialize the armor protection.

He raised his head slightly and looked calmly at the approaching giant wolf. His fists relaxed at the thought that Professor Lupine hadn't deducted points from him for deserting in class.

"There are many obstacles!" Rogge still did not draw out the wand, but the magic was already taking effect in front of him.

The giant wolf seemed to be stuck in an invisible quagmire. Its rapid movements became extremely slow, and every movement became clearly visible.

"Very good, 5 points for Slytherin." Lupine nodded slightly and spoke highly of Rogge's skills in casting spells without a wand.

With a tap of his wand, the giant wolf transformed back into its original dark blue ink bottle.

"Did you all see clearly?" Lu Ping looked around the classroom and asked softly: "Who can tell me what happened in the battle just now."

The students below looked at each other in silence, as if they were still recalling the wonderful scene just now. Only the chandelier overhead made a creaking sound as it swayed, reminding everyone of what had just happened.

Rogge returned to his seat and continued his airship design in Professor Lupin's peripheral vision.

"Professor!" Contrary to everyone's expectations, this time it was Harry who raised his hand to answer the question. Hermione, who was always one step ahead, frowned, seeming to be thinking about deeper issues.

Lupine raised his hand, signaling Harry to stand up and answer.

Harry looked back at Roger and deliberately raised his voice and said, "The professor first used the Expelliarmus spell, and then the Transfiguration spell, and the whole process was silent."

Many students exclaimed, not expecting Harry to be able to identify the specific spell just from the movement of his wand and the light of magic.

A trace of pride flashed in Harry's eyes, and he continued: "The first spell was not only blocked by the armor, but also bounced to other places. This is what the professor said, magic can resist magic, except for the Unforgivable Curse. ”

Lupine smiled and nodded, and Harry's answer accurately captured the key points of the demonstration just now.

"The second spell is full of obstacles, which can block the movement of objects. But if you look closely, you will find that the armor protection does not play any role in the whole process. This also proves that the armor protection is only effective against magic spells."

"But in my opinion, Mr. Rogge's reaction was a bit slow. If it were me, I wouldn't have let the giant wolf jump on top of my head." He raised his head slightly and looked in Rogge's direction. "It just jumped together. I can block it with obstacles."

However, Roger seemed completely immersed in his own world. Without raising his head, he continued to draw the airship design on the parchment. Harry even began to wonder if Roger had heard his analysis and evaluation.

"Harry, if it were you, your head might be in the inkpot right now." Draco seized the opportunity to taunt, and said in his usual provocative tone: "Poor Wolf inkpot, it's going to be yours." My little head is so full."

"Hahaha..." Pansy, Goyle and others laughed in unison, looking at Harry with eyes full of teasing.

As someone who had faced Voldemort before, Harry didn't mind their teasing. He looked directly at Malfoy and challenged: "How about we compete?"

"Ahem!" Lupine coughed loudly, with a slightly harsh tone, "This is a classroom, not a dueling club! Harry answered very well, five points for Gryffindor."

"Malfoy, if you cause trouble in class for no reason, I will deduct your house points!"

His eyes swept over each student. When he passed Roger, he was slightly startled, but then skipped him and said, "Hermione."

"Professor, is there a mechanism in your sleeve robe?" Hermione's powers of observation exceeded everyone's expectations, and even Roger couldn't help but raise his head and take a second look at Lupine.

Lupine nodded heavily and said loudly: "Excellent! Miss Granger's observation and thinking skills are very good. 10 points for Gryffindor."

He said as he took off his robe, "If you look carefully, you will find that many wizards use grips on their wands."

"Its origins are complex, but what is certain is that it is extremely effective in combat."

Lupine motioned for everyone to take out their wands, and then said: "The wand has two parts: the core and the handle, and the wizard only touches the handle."

"So, it must feel very good and have a certain degree of anti-slip ability. But the problem is that most of the wood used to make wands has a smooth and not thick tail."

He further explained: "For example, Hagrid, I and the freshmen, the feeling of holding the same wand is completely different. In order to balance this problem, the handle came into being."

Lupin gently pulled the handle off his wand with both hands. In the sunshine, many people noticed that the handle was connected to a thin line.

"You can carve your own handle according to your hand shape and grip, or you can buy someone else's from Diagon Alley."

"And the mechanism Hermione just mentioned is this thin line on the handle." Lupin raised his hand above his head and gently let go, and the handle fell off.

However, it did not fall to the ground, but was suspended... no, hanging in the air.

"Professor, it's a rope!" The students exclaimed.

"That's right!" Lupin loudly affirmed everyone's answer, "This is a magical rope, only 1/2 the thickness of a hair."

He introduced the use of the retractable magic line in detail: "One end of it is fixed on the handle, and the other end is tied to my ring finger.

With just a slight pull, the handle will be quickly pulled out from the belt. It goes into the sleeve and finally falls into the hand." The finger then pulled, the rope quickly contracted, and the handle fell into the palm accurately.

"Oh, that's it. No wonder the professor can take out the wand so quickly, I thought it was a flying spell."

"It must not be, Professor Lupin has mastered silent casting, but not wandless casting. How can he summon a wand with a flying spell without holding a wand?"

Lupin did not stop the students' discussion, but encouraged them to further understand magic and related skills through debate.

"How do you know the professor can't do it? Hum, I saw the professor just let Roger go, otherwise..."

"What else? The accuracy of wandless casting is very poor, if it weren't for the obstacles and..." He suddenly thought of something and raised his hand quickly.

Lupin nodded with satisfaction, praising the student's inference.

"Professor, the range of the obstacles and armor protection is very large, so wandless casting does not affect the accuracy." He boldly put forward his own guess.

"That's right!" Lupin's answer weakened the discussion in the classroom. "If you use a wand to release the armor protection, the reflected spell will most likely return to the original path."

He emphasized: "Although wandless casting is an advanced skill, as a wizard, it is best to use a wand."

Then, Lupin took out a wooden box and distributed the retractable magic line inside to the students for free.

"In the next class, I hope you can make your own wand handle and master the skill of quickly pulling out the wand. The student who takes the shortest time can get a gift from me."

"Gift?" Everyone became excited when they heard the reward promised by Professor Lupin. Especially Harry, his eyes flashed with determination to win.

Roger also put down the quill pen and tested the magic line in his hand with interest. Although it was very thin, it was very tough, and it was particularly fun to stretch and shrink.

Even if he opened his arms, he couldn't test the limit of the retractable magic line, as if it really had the ability to retract infinitely. Rogge then gently pulled it, and the entire line quickly retracted.

Before this, Rogge had never seen such an interesting magic prop in the magic world. Simple, practical, combined with the handle of the wand, it was completely born for combat.

Suddenly, he remembered that he had promised Dawlish to help make a batch of amulets for the Aurors, and he almost forgot it.
