In the minds of most wizards, Rubeus Hagrid's most prominent labels were naturally "big oaf" and "giant with incredible strength."

Especially those Hogwarts professors or Death Eaters who knew some inside information, they didn't doubt Hagrid's loyalty, but they also looked down on Hagrid's magical abilities.

In fact, it was too obvious that Hagrid was a half-giant.

Normal people couldn't possibly develop to a gigantic size of nearly four meters, not to mention his incomprehensible strength and super-strong defense against magic. Any wizard with relevant magical knowledge could deduce it logically...

There were many half-blood wizards in the wizarding world, so it wasn't hard to guess.

Perhaps half-goblin, half-Veela, half-elf... these were very easy to associate with super magical abilities, but giants were obviously not on that list.

Not to mention, Hagrid was a half-giant who dropped out of school halfway, and in the past few decades, he didn't even have a complete wand.

Therefore, even Professor McGonagall and Professor Snape subconsciously thought that Hagrid had no magical talent.

As Rubeus Hagrid was temporarily substituted into the game, what they thought about the most was ending the match with physical attacks.

However, as a fellow half-blood wizard, Ailina didn't think so.

In her "prophetic" view, Hagrid was definitely one of the most seriously underestimated wizards, even ranking among the top underestimated ones.

Compared to other members of the Order of the Phoenix, under the rigid and solidified thinking of the wizarding world, this powerful half-giant hadn't perfectly displayed his due strength.

First of all, the giant bloodline might not be a side effect on whether a person possesses magical abilities to reach the level of an ordinary wizard.

You must know that Hagrid wasn't the only wizard with giant blood in today's magical world. Madame Maxime, another half-giant, was the headmistress of Beauxbatons Academy of Magic.

As the development of magical bloodlines gradually increased, Ailina could very clearly feel the amplification of magical bloodlines.

The most powerful thing about half-blood wizards was that they could use the magic power of those magical bloodlines in their bodies as a base value, and also enjoy the high magic power growth coefficient unique to human wizards. Although it varied slightly depending on each person's physique, with the initial stats and growth both enhanced, half-blood wizards rarely fell below the average level of ordinary wizards.

As for dropping out of school halfway, if it were just some simple spells, ordinary magical families' small wizards who didn't go to school could try to release them with their parents' wands.

Small wizards who didn't come from the magical world could also learn some simple magic on their own after receiving textbooks, and after one or two years of study, they could even use curses outside of the textbooks.

Dropping out of magic school didn't mean that there was no room for improvement from then on. Gellert Grindelwald and Newt Scamander also dropped out halfway, but this didn't prevent them from becoming one of the top wizards of this century. In fact, apart from these two seemingly not very valuable strong people, many pure-blood wizards would also choose to teach their children at home.

Especially in some European and Asian magical families, even if they didn't choose magic schools, they could still systematically and completely learn magic according to various textbooks and documents.

Not to mention, Hagrid had been in Hogwarts for the past few decades. Even if he hadn't been studying in class all the time, he was definitely not bad in the field of applied magic.

After the Ministry of Magic forcibly broke Hagrid's wand back then, Dumbledore's behind-the-scenes resistance wasn't just keeping him at Hogwarts.

As the current owner of the Elder Wand, he secretly repaired Hagrid's wand and "hinted" that Hagrid hide it in an umbrella to use secretly.

After being strengthened and refined by Ollivander, Grindelwald, Nicolas Flamel and others, the current "umbrella wand" almost surpassed 99% of wands.

According to the evaluation of Ollivander and others, it was no longer just a wand, it was more like a magical device loaded with wand function modules—after all, the effect of a conventional wand was to amplify and stabilize the release of spells, but the "amplification" effect of the "umbrella wand" could cause qualitative changes in some spells, for example... the huge magical shield that appeared in front of everyone.

In Ailina's estimation, the enhanced *Protego* almost reached magical immunity in terms of magical defense ability.

However, the more important point was that this spell also possessed physical resistance and a certain collision volume.

"This, this can... this can be considered magic?"

"Cheating! It's definitely cheating, he even pushed them down directly!"

In the Slytherin House stands, as Hagrid easily swept down his opponents with the magical shield in his hand, the small wizards who watched the whole process instantly exploded.

If the previous spells were just ineffective, then when the light blue hexagonal honeycomb structure shield appeared, all magic turned into silent beams.

Rubeus Hagrid didn't even use a second spell or any attacking action. He just easily pushed forward with the umbrella, but such an ordinary horizontal push couldn't be resisted by anyone. The two Slytherin students were like foam people hit by waves, pushed off the stage without resistance, as if they didn't exist at all.

On the Hogwarts faculty stand, the expressions of the professors were also particularly strange.

Honestly, if they were on the dueling ground below, they couldn't think of any way to counter it for a while.

The key point was that Hagrid hadn't used any attacking spells from beginning to end. No one knew how terrifying it would be if he turned from defense to offense.

"Apocalypse Magic Shield - Practical test results: resisted 63 spells, negligible damage."

Ailina tapped her magic book lightly with her wand and recorded the data.

In the magical world, the birth of any powerful "magical device" was accompanied by danger. Before these things were officially put into production, they had to undergo a series of experiments.

Undoubtedly, the thick-skinned Rubeus Hagrid was obviously the most suitable person to be the chief tester.

If it weren't for the fact that this was Hogwarts, she would even want Hagrid to try Apparition.

In the "admission placement exam" a few months ago, she compiled a detailed "spell list" held by Hagrid, and the result was much better than she expected.

From that "spell list," this half-giant was equivalent to the o.w.l.s passing line standard and could be used as the average strength parameter of the magical world—if Rubeus Hagrid could normally use magical devices, then after safe quality inspection, it could definitely be transferred to the assembly line and promoted to every wizard. This was the new era of magical devices that she ideally envisioned.

As for why Hagrid wasn't used to solving problems with magic before, and even mostly relied on physical combat in the original book, Ailina wasn't surprised.

After all, compared to his physical strength level, the magic he could exert before was slow to cast and low in damage.

However, it was different now.

"Mr. Hagrid, try using a magical impact this time."

Looking at the second round of Slytherin House's arena match contestants standing on the dueling ground, Ailina said softly.

"By the way, remember to unfold the umbrella surface, but... why don't you try pointing the umbrella handle in the 'enemy' direction this time?"

As the founder of the "Binary Reversion Architecture Transformation Magic," her control over sound was long past the initial stage.

Although in her original plan, Hagrid's test subject should have been Dolores Umbridge, who hadn't returned to school yet, the current situation didn't seem too bad.

She wasn't optimistic about Professor Snape's potion offensive from the beginning. What they were really suitable for was large-scale legion warfare, or offensive operations in confined spaces.

In this open terrain, whether it was ancient or modern, whether it was the magical world or the non-magical world, what dominated the victory was always the most simple and unpretentious heavy armor shields and ultra-long-range heavy artillery.

In the first round of the duo magic confrontation just now, the "Apocalypse Magic Shield" perfectly resisted the continuous attacks of two fourth-year wizards for several minutes.

So now...

Magical impact?

Try using the... umbrella handle to point forward?

Rubeus Hagrid frowned in confusion. In his understanding, he had never held the tip of a wand to cast a spell.

However, he still chose to believe in the little angel above, reversing the umbrella and pinching the tip, turning the umbrella handle outward like an inverted mushroom.

After all, apart from Albus Dumbledore, Ailina was the second wizard who truly wanted to help him and had seriously put it into action over the years.

"Wait, wait... what is Mr. Hagrid doing?"

"Is he planning to hit himself?! Mr. Hagrid, don't!"

"Could it be that Slytherin House lost some mind-altering potion again?!"

At the same time, a cry rang out from the Gryffindor stands, and people looked nervously at the giant who turned the "wand tip" to point at himself.

"Magic... impact."

Hagrid said in a deep voice, holding the slightly hot tip of the magic umbrella in both hands.

A white magical light lit up from Hagrid's hands, spreading from the tip of the umbrella towards the surrounding ribs, and finally gathering on the outermost handle like a spider web. A light like a brilliant sun gradually lit up there.

"Damn it!"

"Danger! Get out of the way!"

On the Hogwarts faculty stand, Severus Snape's face suddenly changed, and he quickly stood up and pulled out his wand.

Before anyone else could figure out what he was talking about, the next second, a dazzling giant beam of light flashed through everyone's vision in the center of the field.

Boom!

Along with the huge roar, half of the field's sand and stones seemed to be lifted up by some ancient monster.

A trace emitting scorching heat appeared in the center of the field, extending from Hagrid's feet to the area where the Slytherin contestants were.

"Phew..."

"Gryffindor House wins!"

"It hurts a bit, it seems I was careless, it's much stronger than I thought—"

In a cloud of smoke, a petite, slender figure loomed.

Ailina gently rubbed her wrist, her lake-blue eyes swept across the smoke, and she whispered in a clear, cold voice.

"Gravity—"

The dust in the sky was solidified in an instant, like a sudden landslide, falling vertically to the ground.

Ailina hovered lightly in mid-air, the streamlined blue and white armor outlining her slender waist and "straight and slender" legs, like a Valkyrie in mythology.

The blade-like tail wings spread out like a skirt, just protecting the two fifth-year Slytherin students who were frightened like mud figures behind her. Her waterfall-like silver hair was divided into pigtails, fluttering without wind behind her, and the pure white chest armor outlined two beautiful arcs in front of the girl's chest.

In front of her, a familiar light blue hexagonal honeycomb shield was gradually disappearing...

"I announce that the competition this morning... is over."
