Dark Assassin Transformation Ritual

Dad's Tracking Magic

—Magic? More like potion.

—Sparrow eggs, eel saliva, goat milk foam, snake tail, the target's personal item... what kind of potion recipe is this?

Herpo's Diary (Fragment)

—Just happens to be records on raising Basilisks, I can refer... refer my ass!

—Eyes, right? Where the hell am I supposed to get that many eyes?

—Wait... eyes? Acromantula!

—I'll just have to put Hagrid through some hardship.

"At least two Silvers."

Harry suppressed his anger, letting the new magical knowledge churn in his mind.

Even though Dragon Syphilis was incredibly strong—if Lucius Malfoy's dad caught it, he'd only be waiting to die.

But who the hell wants that!

"Fang, venom sac, decompose!"

[..., Obtained 6 [Trait Gems]]

"Look on the bright side, at least upgrading a Golden Affix only needs one now."

Harry's gaze fell on [Flobberworm Regeneration].

—After an upgrade, it should be decent. I'll keep it.

"Everything else, accept!"

Harry took a deep breath. He hadn't been directly modified in the brain before; the Troll's power rampaging into his head was only indirect.

The next moment.

Harry felt a tingling numbness spread through his body, and his feet automatically lifted off the ground, almost exactly like the sensation described in books of being injected with Billywig venom.

The only difference was...

This floatation wasn't uncontrollable. He could feel this power bending to his will like his own fingers, easily "twisted."

The brain undergoing transformation sent back no sensation at all.

Only when the childhood feeling of losing a tooth, the taste of mother's milk, and the memory of riding a toy broom surfaced one by one did he realize the transformation was complete.

—Perhaps I could recreate the light-footed arts from wuxia worlds?

—Crossing a river on a single reed, treading atop grass, standing on treetops...

Harry felt his new self, and time began to flow again.

"Another new day."

A tall figure stepped directly out of a thick tree trunk.

Deep within the Forbidden Forest.

Here was a gap in the dense canopy woven by thousand-year-old branches, where light was no longer a luxury.

Harry looked up.

Before him stood a steep cliff face, covered in slippery moss and vines.

Nearly a week had passed.

Ever since he mentioned the Killing Curse in the Room of Requirement, Hermione and the others had treated everything he did as forced bravado, looking at him like fragile porcelain.

The first to catch this gaze was naturally Sirius.

The dog godfather started asking questions all day long, imparting dating advice to Harry.

Next came Hagrid, who took the initiative to lead Harry through the Forbidden Forest and feed the Thestrals.

Then Professor McGonagall and the others...

But now, he wasn't here to escape the noise.

He was training.

Burrowing through the earth of the Forbidden Forest had become his new habit.

The bones of various magical creatures, tree roots plunging deep into the ground, and ores became the scenery of his training.

Unfortunately, Ravenclaw's Diadem had yet to be found.

[...[Slack Off and Fish][Literature and Sports Both Bloom][Potter Combat] Proficiency +1]

"Next up, rock climbing."

Harry turned into a blur as he charged toward the cliff face. His body seemed to lose all weight; each time his toes tapped the slippery moss without any protrusions or cracks, his body swung through the air, carving a sharp arc.

His movements were flawlessly fluid, each leap carrying a wild yet graceful rhythm.

He raced as if on flat ground, heading toward the cliff's summit and the rising sun.

Just as his figure overlapped with the sun and he leaped onto the cliff's edge, a paper crane appeared at the sun's center.

Mysterious cloud-script runes surfaced on its snow-white surface.

The next moment, with a sharp sound of air being squeezed aside, it appeared at the edge of the Forbidden Forest.

Silently, it transformed into a human shape.

"Hagrid!"

Harry stepped out from behind a tree, waving at the half-giant emerging from his hut, making no attempt to hide that he'd been in the Forbidden Forest.

"King Harry (dog-speak)!" Fang greeted him first.

"Did you run into Aragog?" Hagrid asked worriedly. "His colony's been taking heavy losses lately. But in the Forbidden Forest, they have no natural enemies."

"Unicorns eat plants, Centaurs hate the dark and live on the other side where the light reaches."

"Werewolves are in the deepest parts."

"Trolls... maybe it's the trolls!"

—Who knew they had so many eyes.

—You know they have no natural enemies, don't you.

Unable to find eyeballs, letting Arbok eat the Acromantulas directly, Harry, now possessing troll strength, no longer felt guilty.

—These are necessary sacrifices, for [Arbok].

"What about the trolls?"

"Acromantulas can't bite through troll skin, and their weak spot—their heads—are too small."

Hagrid said seriously.

"Trolls aren't as weak as you think. For a long time, smart trolls that could speak a few words were the top picks for security."

"Give them a sturdy helmet, and they won't even fear dragons."

"Quirrell only got hired as the Defense Against the Dark Arts professor because he was especially good at dealing with trolls."

"That's a secret." The half-giant, as if raised on Veritaserum, said proudly.

"He's especially good with trolls?" Harry was surprised.

It wasn't that Harry didn't know—Quirrell had mentioned it while boasting in the original story.

The other professors should have known too, after all, the trap Quirrell set was a troll.

It was just that Harry hadn't known Quirrell was skilled at handling trolls, to the point that even Hagrid knew.

Then that Halloween when Quirrell fainted...

That was way too obvious, clearly a covert cry for help.

"Of course." Hagrid nodded.

He rubbed his palms together, glanced at Harry's thin robes, then at his own Moleskin Coat.

He caught a snowflake and held it out.

"It's almost November now, how can you still be wearing so little?"

"Almost November?" Harry's eyes went wide. "That means... Halloween is almost here."

—This time, would Quirrell still let a troll in?
