With extraordinary comprehension, I built a floating city at Hogwarts.

This shortcoming was not remedied until the 4th level [Advanced Stealth].

The continuous chanting of incantations coming from the women's restroom alerted the giant to the presence of someone hiding inside.

It began to lower its head, trying to crawl inside.

Seeing the situation becoming urgent, Hermione hurriedly said, "You left the invisibility spell to me, what are you going to do now?!"

“Don’t worry,” Levin said calmly. “I have magic to protect myself. That troll can’t hurt me. You hide to the side for now, and take the opportunity to run away when I fight the troll.”

Levin asked her to leave because he thought she was in the way.

But Hermione interpreted it as Levin sacrificing himself to distract the troll and give her a chance to escape.

Even Levin's confident voice sounded tragic to her.

"No... I won't leave you alone." The little witch said, her voice trembling with tears, as she pulled out her wand again.

“…What are you doing? Don’t waste my spells,” Levin said helplessly. “Your magic won’t hurt it anyway.”

As he spoke, Levin took the initiative to demonstrate:

"Except your weapons!"

A red light emanated from the tip of the wand, striking the troll precisely on the shoulder.

But nothing happened.

The troll blinked foolishly and turned its ugly, large nose toward Levin.

Ordinary wizard spells couldn't harm this giant monster at all.

Levin originally intended to demonstrate this to Hermione.

But little did she know that the little witch had misunderstood from the start, which only made her more confused:

Even if you can't hurt the troll, you still stay to draw its attention. So you're such a great person?

Don't worry, I won't let you down!

"I...I understand. I will find the professors to help you as soon as possible. You...you must hold on!" Hermione said, trembling as she hid in a nearby cubicle.

Only then did the troll realize that the little guy in front of him had just attacked him.

So it raised its wooden club high, roared, and approached Levin.

"【Frost Armor】"

Instead of launching an attack immediately, Levin cast a defensive spell on himself.

This is also the typical combat strategy of arcane mages—protect yourself first, then seek control, and finally kill the enemy.

Instantly, Levin was surrounded by invisible armor.

Hermes felt a chill in the cubicle.

"He's using his own spells again," she thought. "He always has a bunch of his own spells."

The troll felt the chill even more intensely than the little witch.

—The closer it got to the tiny creature in front of it, the more it was frozen by the cold air and its movements became sluggish.

This is the slowing effect caused by the Frost Armor's increased defense.

Levin, of course, wouldn't waste this opportunity. He raised his wand again and tapped it repeatedly at the giant in front of him.

One after another, beams of blue light shot from the tip of the wand toward the giant.

It is a level 0 spell, [Freezing Ray].

Although this spell doesn't deal much damage, its advantage lies in being a level 0 trick, requiring minimal preparation to cast, making it perfect for emergency situations.

Several beams of light all struck the same spot—the shoulder of the giant's staff-wielding arm.

Suddenly, a thin layer of frost appeared on the troll's right shoulder.

It grew thicker and thicker under the relentless barrage of fire, eventually freezing into a solid sheet.

The giant barbarically approached Levin, twisting its waist, shaking its shoulders, and swinging its arms, unleashing all its power through its muscles and magic in one fluid motion, ready to crush the little thing into mincemeat with a single blow.

But the imagined scene did not happen.

The bewildered giant stood there stunned for several seconds before realizing that he had only performed the waist twisting part of his movements.

None of the subsequent actions were successful.

Because my shoulders were frozen.

To Levin and Hermione, the troll simply ran up to them and awkwardly bent down.

The arm that was gripping the wooden stick was still raised high on the shoulder.

Hermione almost burst out laughing at his comical appearance.

However, the composed Levin did not do that. He seized the opportunity and had already prepared a second spell:

"[Frost Arrow - Ice Blade Technique]"

When casting Frostbolt, Levin spent considerable effort reshaping the magic.

The originally sharp ice arrows were transformed into sharp ice blades and shot towards the giant's frozen shoulder.

While trolls possess strong magic resistance, they offer little protection against cold damage.

The rough yet resilient outer skin becomes extremely fragile under the influence of the [Frozen Ray].

The ice blade struck, severing the giant's arm at the shoulder, as if it had been cut by a sharp knife.

But under the effect of freezing, it can't even feel pain.

"Wow, Levin, you're amazing!" Hermione exclaimed.

Levin was also very satisfied with this; it was exactly the outcome of the battle he had envisioned.

Having lost its arms and weapons, the giant immediately lost most of its fighting power.

With just a few minor spells, this big guy can be easily subdued, and today's spell experiment will be declared a success.

Just as Hermione was excited and Levin was planning to press his advantage,

The troll picked up his arm and pressed the severed end to the wound on his shoulder.

Then, something unbelievable happened to the two of them.

The moment the flesh at the monster's wound touched the ground, it began to grow wildly, the rising and falling buds of flesh a horrifying sight.

In less than two seconds, the troll's severed arm was perfectly reattached.

Chapter 33 Fiery Rebirth

—No, the reattachment of this severed arm cannot be described as completely intact.

It could even be said that the restoration was quite crude:

Lai Wenming clearly noticed that the reattached arm was slightly crooked—the texture of the skin at the interface did not align perfectly—and it was also longer than the previous one, resulting in one arm being longer than the other, making it look extremely uncoordinated.

But that's the scariest part.

Even with this crude method, the troll still managed to reattach its severed arm, and the reattached arm was still usable.

This shows that the troll's ability to recover was entirely due to its incredible regenerative capacity.

But how is this possible?

I've never heard of trolls in the Harry Potter world having such regenerative abilities!

This is how the same thing?

Levin's brain was working at lightning speed.

A database of numerous spellbooks was of no help.

Instead, his memories of his past life provided him with clues:

"Could this troll be a combination of characteristics from trolls from other worlds?!"

Thinking of this, Levin suddenly realized something.

Yes,

It's unbelievable that Ciri from the Wizarding World could appear in this world.

Water ghosts can appear in this world,

Why can't the trolls of this world merge with the trolls of another world?

After all, they are all the same species.

Unlike the trolls in the Harry Potter world,

Whether in World of Warcraft, D&D, or the Wizarding World, trolls are a race known for their regenerative abilities.

Troll wounds heal very quickly; even if the monster loses its limbs or head, the dismembered parts will still maintain life.

Some trolls will even reattach severed limbs to their original positions.

Even more absurdly, if the trolls don't reattach the severed limbs, those limbs will even fight automatically, as if they were alive.

You'll see a hand crawling around on the battlefield, a leg hopping around, or a head that bites—until the troll reattaches its severed limb or grows a new one.

Clearly, the giant in front of us is able to reattach severed limbs because it has absorbed the abilities of its counterparts from another world.

If we say that the original giant's combat power was equivalent to level 5-6,

So this guy, who now possesses both the magic resistance of a troll and the regeneration ability of a troll, is completely equivalent to a level 7-8 wizard.

However, the troll's incredible regenerative abilities are not insurmountable.

Levin's otherworldly knowledge told him that only strong acid and fire could stop the troll's body from regenerating.

"Well, we made it in time, didn't we?"

Levin gave a smug, cold laugh.

"Here comes the [Fireball] spell that I just developed."

As he spoke, he waved his wand and recited the spell he had just learned that day:

"[Monster Summoning Technique]"
