Flying Broomsticks, more often simply referred to as Brooms.

These are one of the aerial transportation methods used by wizards and witches in the magical world to travel from one place to another.

Since wizards haven't invented any spells that allow them to fly in human form without any tools, they had to come up with other ways to make themselves fly.

Animagi can enjoy flying after transforming into winged animals, but this is extremely rare.

Long before the International Statute of Wizarding Secrecy was implemented, wizards were keenly aware of the need to conceal their magical abilities when living among Muggles.

Therefore, if a wizard wanted to have a flying tool in their home, it had to be inconspicuous and easy to hide.

At the time, a broom was an ideal item—easy to carry, inexpensive, and could openly exist in the home.

The earliest flying broomsticks were neither comfortable nor aerodynamic.

The earliest record of flying broomsticks in the magical world appears in a German manuscript from 962.

At that time, flying broomsticks were often just a rough, unpolished ash stick, with a few hazel twigs casually tied to one end, neither comfortable nor aerodynamic.

In 1107, Scottish wizard Guthrie Lochrin wrote after flying from Montrose to Arbroath that his "buttocks were full of thorns and had grown bumps."

Naturally, the spells applied to it were also basic:

It would only fly forward at one speed; it would not rise, descend, or hover.

However, in the early twentieth century, with the successive establishment of various flying broomstick companies, the industrialized production chain rapidly made flying broomsticks the darling of the modern magical world.

At least in the UK, almost every wizarding family owns at least one flying broomstick.

On the other hand, in addition to the essential flight function, flying broomsticks can also respond to some of the simplest commands, such as...

"Up—"

Elena held out her right hand, pointing it forward.

The next moment, the giant metal broom lying quietly on the ground slowly floated up, sticking to her palm.

She turned to look at Hermione, nimbly jumped on it, and sat sideways on the floating metal creation as if sitting in a rocking chair.

"Just as no matter how big the Hyperion is, it is still a ship. A larger, harder material flying broomstick, as long as it can fly, is of course a flying broomstick. If you are surprised to see this, then you are too impatient..."

Even if this "flying broomstick" is not made of common wood, even if it is thicker than a club in the hands of an adult giant.

But with just Elena's ordinary action, even if officials from the International Flying Broomstick Confederation were present, there would be nothing to question.

"Valkyria I, this is a top-level flying broomstick jointly developed by Hogwarts, Gringotts, and Destiny Group. All related data is currently at the highest level of confidentiality—equivalent to the real data of the Hyperion."

"According to the latest relevant parameter tests, it weighs 2.33 tons in broom form...of course, it is equal to zero after magic activation."

"It accelerates from standstill to 200 miles per hour in ten seconds, and is equipped with a powerful braking charm, which can automatically hover at any height."

"As for the ability to withstand strikes...let's put it this way, it can easily withstand 1000 kg armor-piercing projectiles and 2-ton anti-ship missile strikes from the front. Or withstand a full-strength pure energy curse from a wizard of Professor Dumbledore's level."

"But, it doesn't seem suitable for competitions, and no one would throw bombs or cast spells on the playing field—"

Hermione glanced at Elena, calmly pointing out the shortcomings of this strange broom.

"Obviously, as a flying broomstick, its diameter is too large. Unless it is a wizard with a physique like Hagrid, most people can only use a side-sitting posture, and high-speed movement and direction changes must be done in a straddling posture...it is not practical."

"Well, that is a problem."

Elena nodded, lightly patted the broom, and swiped a 360-degree pendulum in the sky, returning to the original point while sitting sideways.

"Therefore, we have referenced a series of other countries' flying props such as magic carpets and flying swords, and added corresponding spells to the Valkyria I to ensure that users will not fall off the broom due to inertia, and side-sitting can also be at maximum speed and variable speed at any time—"

"Are you planning to bring it out in the upcoming Quidditch match?"

Hannah looked at Elena curiously, "If it's this broom, it can block the Bludgers we throw, right?"

Although she didn't understand those complicated parameters, Hannah could roughly understand some concepts.

For example, this thing is very hard, very durable...

Because Elena used more adjectives and examples when describing the ability to withstand strikes.

"Well, theoretically it should be possible—"

Elena blinked her eyes, subconsciously answering.

Before the light in Hannah's eyes could brighten, she immediately added.

"But you can't play with this for the time being, this is not developed for Quidditch matches—these flying broomstick models are just to give her a corresponding reasonable identity, just like more than a thousand years ago, we wizards turned brooms into flying broomsticks."

"So—"

Luna Lovegood looked thoughtfully at the broom in Elena's hand.

"This is not her real appearance now, right? Maybe it's like...an Occamy?"

"Exactly!"

Elena narrowed her eyes smugly.

Hermione, Luna, and others were familiar with this expression.

When the corners of the white-haired ball's mouth raised to this arc, it usually meant that she was extremely proud and smug.

However, in their memory, even when she led the freshman team to win the championship last year, Elena didn't seem to be so smug.

"Is the Valkyria I debugging completed? Can it be deployed?"

Elena turned around, looked at the researchers standing beside her, and asked softly.

Only then did Hermione and others realize that, unknowingly, everyone in the hangar had stopped their work.

Everyone silently surrounded a large circle, looking forward to Elena in the center, or rather, the giant steel broom under her, as if waiting for some major ceremony or performance to take place.

"There are still some problems with the electronic control system, but it does not affect the activation of the mobile module...let me see—"

The project director in charge of the Valkyria I looked at the schedule and continued.

"Since your last deployment debugging, we have made adjustments to the armor space, completed the deployment armor in each position, but have not yet connected the system in series..."

"Well, simply put, the modeling is complete, but the skills have not been applied yet, right? Got it."

Elena quickly summarized, glancing around the cluttered hangar.

Honestly, this progress is already very fast.

Compared to the last test, it has only been less than a month.

Sure enough, is this the collision of the most advanced human civilization?

It was worth it for her to spend another time borrowing the Philosopher's Stone from Nicolas Flamel for this.

Then, she lightly jumped off the broom, her palm facing down and stretched forward.

A "weapon" shimmering with metallic luster floated in front of her chest like the legendary ancient wand.

"As you can see, first is to be activated—"

Elena smiled at Hermione, Luna, and Hannah.

"Don't blink, remember my steps. It's very simple, there are only three steps in total, and it will be about the same when you deploy your own Valkyria later. Of course, that may have to wait at least half a year...after all, this prototype is still in the debugging stage."

"Mysterious, anyway, no matter how good a flying broomstick is, it's all the same to me."

Luna heard Hermione mutter unhappily in a low voice, obviously not so interested.

"The second step, authorization code input—temporarily my wand."

Under their gaze, Elena took out her wand and placed it in the slot on the side of the broom, making a crisp click.

"Finally, liberate Valkyria."

Elena gently tapped the metal handle floating in front of her with her index finger.

"Valkyrja Operational—"

Suddenly a dazzling blue light flashed, and the seemingly indestructible giant metal broom quickly disintegrated.

As if a Pandora’s Box had been opened, dozens of regular metal blocks of different sizes floated around Elena.

Those armor plates shimmering with metallic luster and having a fascinating unique beauty, like moths chasing the light of fire, hovered around Elena, with Elena in the center slowly floating up, hovering in mid-air with her limbs relaxed as if in water.

Light blue arcs connected between the blue and white metal armor, aggregating around Elena and outlining a light net.

As the light became more and more dense, the grid became denser, and the surrounding metal armor began to extend and deform.

The original somewhat exaggerated and huge blue and white metal armor gradually shrunk, tightly covering Elena's body to form armor.

Arms, thighs, abdomen, chest...

Finally, a streamlined armor structure extended backward from Elena's waist, forming two wings like blades.

Unlike the medieval armor transformed by the armor charms of wizards, the blue and white armor covering Elena's body perfectly outlined the girl's figure, without any excess protrusions that would affect flight, looking light, agile, and full of power.

The light gradually dissipated, Elena slowly opened her eyes, her lake-blue eyes cold and calm.

Suddenly touched by Elena's gaze, Hermione, Luna, Hannah and others subconsciously stopped breathing for half a second.

However, the familiar agility and cunning returned to her eyes the next moment.

"How is it, you didn't expect it, did you? Isn't it beautiful!"

Elena lightly glided across the hangar dome, silently landed in front of the three little ones, and gracefully unfolded her long tail wings.

"Valkyria I, the prototype is the SU-17 and the Firebolt under development by Gringotts, a single-soldier magic armor formed by hundreds of spells such as the undetectable extension charm, braking charm, shock-absorbing charm, and armor charm - modification. The estimated maximum speed is Mach 1.9, and the reinforced tail wings at the highest speed can theoretically shred most conventional armor in the world today."

"Because the hybrid propulsion system has not been debugged yet, it is still pure magic braking for the time being, and the maximum speed is only Mach 0.22."

"Of course, this is already twice as fast as the fastest broom in the magical world today."

"And only after the numerical control system and weapon system are debugged can it be considered a real finished product. This is the core strength of the Hyperion in the future, the absolutely superior ‘carrier-based aircraft’ and local battlefield terminator—"
