The person is at Hogwarts, but the system is in Middle-earth!

Rowe's expression changed instantly. In the system's view, the sprites transformed into a group of miniature demons with dark skin, sharp fangs, and bat wings! They were clutching daggers and explosive charges, frantically ramming against the cage bars.

"Damn it!" Rowe jumped to his feet, his knee slamming against the table. "Lockhart actually brought this thing into the classroom! It's like throwing orcs into Helm's Deep! All units, prepare for close combat!"

"Alright, let's see how you deal with them!" Lockhart, completely unaware of the danger, opened the cage door directly.

Chaos erupted instantly.

Chaos erupted instantly.

The little elves burst out like rockets. They split into several groups; two grabbed Neville by the ears, lifted him up, and hung him from the iron chandelier on the ceiling. The others began tearing books apart, smashing ink bottles, and even trying to dismantle the classroom window frames.

"Grab them!" Lockhart shouted, rolling up his sleeves. "Peschich Pixie Pestnomi!"

It had no effect. The spell was like tickling the elves. One elf seized the opportunity to snatch his wand and throw it out the window. Lockhart gasped, and at this crucial moment, he did something that shocked everyone: he crawled under the podium, then slipped back to his office in the chaos and slammed the door shut.

"He ran away! That coward!" Ron yelled, a little elf nibbling at his ear. "Is this his 'adventure experience'? That's not what he wrote in the book!"

"Don't panic! Let me try!" Hermione raised her wand, trying to control the situation with a spell. "Freeze—ouch!" A little elf slammed into her wrist, and the wand flew out of her hand.

A little elf slammed into her wrist, and the wand flew out of her hand.

"Ditch that useless stick! No need for fancy tricks this time!"

A roar drowned out all the noise.

Loewy leaped onto the desk, holding "Sailing with Vampires" high in his hand. The hardcover book was a good three inches thick.

[Equipment Switch: Knowledge Guardian's Heavy Warhammer (Excellent)]

[Attack Pattern: Fly Swatter/Paladin's Retribution]

A little elf shrieked and swooped down toward Rowe, waving an ink bottle in its hand.

"Get down, you demon!"

"Bang!"

Lowe swung the thick book and slapped the little sprite against the wall like swatting a fly. The sprite, seeing stars, slid down and turned into a flat sticker.

Immediately afterwards, Rowe performed a tactical roll on the table, avoiding the attack of the two sprites, then swung a book at the left sprite and sent it flying, before smashing the right sprite's head hard with the spine of the book.

The movements are fluid and graceful, relying solely on pure power and speed.

"Harry! Protect Hermione! Ron, use your books! Stop waving like a girl!" Rowe roared, directing the battle. "Treat them like goblins!"

He saw Neville still dangling on the chandelier, and three "goblin sappers" sawing at the chandelier's chain, seemingly trying to cause a plane crash.

"Hold on, Longbottom warriors! Reinforcements have arrived!"

Rowe casually grabbed the leg of a little elf that flew past him.

[Skill Activation: Meteor Hammer Whirlwind]

He treated the squeaking little sprite like a flail, swinging it around with a whooshing sound and throwing it forcefully at the chandelier.

"Slap! Slap!"

The little elf, used as a weapon, crashed into its three companions on the chandelier, sending all four elves sprawling to the ground. Neville then wobbled back onto the table, suffering only minor injuries, though not serious ones.

"This is Gondor's tactic!" Rowe stood on the highest point of the table, surrounded by a circle of dizzy elves. He held up the slightly deformed book, "Sailing with Vampires," his robes fluttering in the wind.

"Go back to your abyss! This is not Moria! Hogwarts does not welcome you!"

The remaining elves seemed terrified by this primal violence. They had seen all sorts of spells in the magical world, but they had never seen anyone use a book as a brick to smash someone, and with such accuracy and force. This was even more barbaric than a troll!

Taking advantage of the situation, Lowe jumped off the table and, waving his large book like a herd of sheep, drove the remaining elves back into their cages one by one. Anyone who dared to resist was immediately met with a "heavy blow of knowledge."

Three minutes later.

"Click".

Lowe closed the cage door, placed a heavy oak chair on top of the cage, and then dusted off his hands.

The classroom was deathly silent.

The entire class peeked out from under their desks, staring in disbelief at Rowe. Neville was still rubbing his ears, Hermione's wand was still on the floor, Ron's mouth was agape, and even the Slytherin students forgot to laugh, simply looking at this Hufflepuff "savage" in shock.

Several little elves lay on the ground, still convulsing, while the others trembled in their cages, no longer daring to let out that annoying scream.

"This..." Hermione stammered, picking up her wand, "This is indeed... very effective. Although it's not very magical."

"You don't need magic to deal with these dishonest creatures." Luo Wei picked up his book, whose cover was already torn, and touched the dent with heartache. "All you need is a firm will and a handy weapon. Sometimes, the laws of physics are more reliable than magic."

He turned to look at the closed office door behind the podium, a hint of contempt flashing in his eyes.

"As for that smooth talker... it seems we shouldn't have any illusions about him. He can't even handle a group of scouts, let alone fight the Dark Lord?"

[Mission Completion: The First Battle of Defense Against the Dark Arts]

[Defeat target: 20 Moria Goblin Engineers]

[Evaluation: You demonstrated the melee art of a ranger, showing the wizards the weight of the laws of physics. Although your actions resembled those of a berserker, the effect was outstanding.]

[Reward: Agility +1, Strength +0.5]

[Achievement Unlocked: [Pixie Slayer] (Intimidation effect against creatures smaller than 1 foot +10%)]

Rowe felt a surge of heat coursing through his body (the sensation of increased agility) and nodded in satisfaction. Although he hadn't learned any defensive techniques, this lesson had at least provided a good practical exercise and allowed him to confirm Lockhart's true skill level.

He glanced at the Slytherin students again and deliberately raised his voice.

"Also, if anyone wants to tell Snape about what happened today, I wouldn't mind giving him a 'physical defense lesson' as well."

Draco Malfoy shrank back, not daring to speak.

Luo Wei strode out of the classroom, leaving everyone with a dashing and elegant silhouette.
