A magical journey that begins in Azkaban

During the Triwizard Tournament, Rogge was contemplating suitable means of transportation. Beauxbatons’ elegant carriage, Durmstrang’s mysterious black ship, and Hogwarts’ iconic express train.

Yes, it's the steam train that carries students back and forth between King's Cross Station and Hogwarts when they're on vacation or when school starts.

It is not limited to that fixed line, but can also run on any railway track in the world. Such an ability undoubtedly made Rogge feel itchy.

He opened a heavy folder, and inside lay more than a dozen carefully designed sketches. There are the Leap of Faith Jackdaw, Diamond Storm Seer, Twenty Thousand Leagues Under the Sea Nautilus, steampunk moving castles, and no-smoking high-speed trains...

Rogge leaned on his seat, with a very troubled expression on his face. Every design was full of creativity and dreams, making it difficult for him to choose.

Of course I want all the adult choices, but why is he not an adult yet? And time is running out, he must make a choice.

Just as he was deep in thought, his eyes accidentally fell on a yellowed photo. It was an aircraft with a huge streamlined body, with a small pod suspended below. The tail gradually shrank and had protrusions similar to fish fins.

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

This name seemed to have extraordinary magic power, making countless possibilities flood into Rogge's mind.

As the most representative aircraft of the 20th century, it combines retro and mechanical beauty, as well as the shocking feeling of giant objects and technology, and perfectly meets all Rogge’s expectations.

He imagined himself riding in such an airship, freely shuttled between the blue sky and white clouds, and going wherever he wanted. The only regret is that the hydrogen in the air bag is a stable explosive that can make people's hearts beat faster.

However, this risk factor is not an insurmountable problem for wizards. Just apply the levitation spell to make it fly high and stable.

"This is it." Rogge said to himself, determination and expectation shining in his eyes.

He began planning how to modify 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, where you can enjoy both the fun of flying and the experience of sailing on the sea. Feel……

He quickly commanded the quill and traced his thoughts on the parchment one by one. As the quill dances, a magic airship design based on the Zeppelin gradually appears in front of you.

It not only has the majestic 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 shape of a Zeppelin airship. From a distance, it looks like a Kun swimming in the blue sky.

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

The second level 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 the rest area, which has several fully equipped and luxuriously decorated bedrooms to ensure that you can enjoy a comfortable rest environment during long journeys.

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

The bottom layer is the cab, which is responsible for controlling the speed, height and attitude of the airship to ensure that the airship can fly safely and stably.

Roger excitedly wrote down the specific purpose of each layer, and planned to use the giant bubble head charm 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 during the Defense Against the Dark Arts class, he was busy designing airships and did not hear Professor Lupine's lessons at all.

"...The Bubble Curse is a very practical magic..." After Lupine learned from Harry that Snape had ridiculed him, a look of helplessness flashed in his eyes.

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

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

"Roger!" Lupine's voice rang in the classroom, his eyes fixed on the student who was completely focused on his world on paper.

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

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

"Huh?" He raised his head and looked around with a confused look on his face. His innocent expression instantly triggered a burst of laughter.

Lupine did not get angry. He said in a calm voice: "Mr. Rogge, please come up."

"Oh, Professor." Rogge finally came back to his senses, with a wry smile on his lips.

"You come to attack..." Lupine'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 mind, "I will attack you, you can only use obstacles and Armor protection."

"No problem." Rogge immediately expressed his 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 that Harry could identify the specific spell just from the movement of the wand and the light of magic.

A trace of pride flashed in Harry's eyes, and he continued to narrate: "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 has to feel very good and have a certain degree of anti-slip capability. But the problem is that most of the wood used to make wands has smooth ends and is not thick."

He further explained: "For example, Hagrid, me and the new students have completely different feelings holding the same wand. To balance this problem, the grip came into being."

Lupine used his hands to gently pull out the handle of his wand. Under the sunlight, many people noticed a thin line connected to the handle.

"You can carve your own grip based on your hand shape and grip, or you can buy one made by someone else from Diagon Alley."

"And the mechanism Hermione just proposed is this thin line on the handle." Lupine raised his hand above his head, gently released it, and the handle fell down.

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!" Lupine affirmed everyone's answer loudly, "This is a magic rope, only 1/2 the thickness of a human hair."

He details the use of the telescopic magic thread: “One end of it is fixed on the handle, and the other end is tied to my ring finger.

With just a slight tug, the handle will be quickly pulled out of the belt. It slipped into the sleeve robe and finally fell into the hand. "Immediately with a flick of my fingers, the rope quickly contracted, and the handle fell accurately into the palm of my hand.

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

"Definitely not. Professor Lupine has mastered silent casting, but not wandless casting. If he doesn't hold a wand, how can he use the Flying Charm to summon a wand?"

Lupine did not stop the students' discussions, but encouraged them to further understand magic and related techniques through debate.

"How do you know the professor can't do it? Huh, I think the professor just gave way to Roger, otherwise..."

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

Lu Ping nodded happily, appreciating the students' inferences.

"Professor, the range of obstacles and armor protection is very large, so casting without a wand does not affect the accuracy." He boldly made his guess.

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

"While wandless spellcasting is an advanced skill, as a wizard, it's best to use a wand," he emphasized.

Then, Lupine took out a wooden box and distributed the telescopic magic thread inside to the students for free.

"Next class, I hope you can make your own wand handle and master the technique of quickly drawing out the wand. The student who takes the shortest time will get a gift from me."

"Gift?" Everyone became excited when they heard the reward promised by Professor Luping. Especially Harry, whose eyes were shining with determination to win.

Rogge also put down his quill and tested the magic thread in his hand with great interest. Although it is very thin, it is very tough, and it is particularly fun to stretch and shrink.

Even if he opened his arms, he could not test the limit of the telescopic magic thread, as if it really had the ability to stretch infinitely. Rogge then flicked it lightly, and the entire line quickly retracted.

Before this, Rogge had never seen such interesting magic props in the magic world. Simple and practical, combined with the wand handle, it is completely made for combat.

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