I Killed the Hero and Took His Achievements-Chapter 10: Eating The Forbidden Fruit

[Location: The Dungeon Training Room]

[Status: Secured. Soundproofed.]

Sylvia Frost was no longer like a Princess. She was a shivering mess of exposed skin and shattered pride.

She knelt on the cold stone floor, her uniform folded neatly beside her. She wore only her undergarments of lace, silk, and expensive and currently futile against the aura of dominance I was projecting.

I sat on the chair and legs crossed. The Usurper (Left Hand) was glowing with a hungry red light.

"You look cold," I remarked. "What an irony."

Sylvia flinched. She wrapped her arms around herself. "I... I can’t feel my mana," she weep. "You took it all."

"I took the control," I corrected. "Your mana is still there, but the ’key’ to access it? That’s mine now."

I leaned forward. "Do you want it back?"

She nodded desperately. For a mage, losing magic is like losing a limb. It’s worse than death. It is utter helplessness.

"Then beg to me."

Sylvia froze. The last shred of her royal dignity fought against her survival instinct.

She looked at my eyes. She realized she was already falling. "Please..." she whispered, her face burning red. "Please... Professor... give it back."

"Louder!" I insisted.

"Please! Master!" She cried out, tears spilling. "I’ll do anything! Just let me cast again!"

"Good."

I stood up. I then walked over to her. I didn’t give her the skill back, not yet. I placed my hand on her bare shoulder. Her skin was soft and trembling violently.

"I’m going to unlock your Mana Circuits manually." I wasn’t unlocking anything. I was branding her and I lied well.

I pushed mana into her body. It was my mana. It was corrosive, dark, and possessive. It flooded her veins, chasing away the cold, and replacing it with a burning and heavy heat.

"Ah! Nngh!"

Sylvia arched her back. Her eyes rolled back.

It wasn’t pain. It was a sensory overload. Her body, trained for ice, was being violated by void fire.

"It burns!" she moaned while her nails scraping the floor. "It’s inside me!"

"Accept it," I ordered. "Let it stain you entirely."

I moved my hand down her spine. Every nerve ending lit up like a Christmas tree.

She collapsed against my legs, panting, sweating, and her body twitching in aftershocks.

She looked up at me. Her eyes were glazed, adoring, and defected. "Master..." she purred. "I feel... full. Plop."

"You are," I said, stepping away. "You now run on My mana. If you betray me, I cut the supply. And you die."

I tossed her uniform back to her. "Get dressed. You have a job."

"Yes, Master." She grabbed the clothes, moving with a desperate urgency to please me.

I checked my watch. "Lesson’s over. Now, for the real loot."

[Location: The Academy Basement - Sector Zero]

[The Vault of Forbidden Knowledge]

The door wasn’t wood, but it was a giant spinning gear mechanism made of metal.

Dean Merlin stood there while holding a complex runic key.

He looked nervous.

"Professor Cross," Merlin warned. "This vault hasn’t been opened in fifty years. The books inside... they aren’t just books.

"They bite, right?" I inquired.

"They consume minds. The last Archivist went insane. He eventually ate his own eyeballs." He said.

"Sounds festive. Now open it for me," I said.

Merlin sighed. He turned the key.

CLANG. HISS.

Steam poured out, then the gate was opened wide.

I walked into the darkness.

"Wait outside," I told Sylvia and Seraphina. "If something screams, ignore it."

I stepped into the room.

The room smelled like an old dust.

Shelves stretched infinitely upward. Books were floated in the air and chained to the walls. Some books were bleeding, some were whispering. One book that was bound in human skin, snapped its jaws at me as I walked past.

"Cute," I muttered whille slapping it with the flat of my dagger.

I wasn’t here for the small fry.

I walked to the center of the room.

There, on a pedestal of obsidian sat a single massive tome. It was pitch black. It was as if it absorbed the light around it.

[Item: The Grimoire of the Void (Original)]

[Grade: Forbidden.]

[Warning: Do not read. Reading causes instant death.]

This was it.

In the lore, this book belonged to the "Demon King of the Void", an apocalyptic boss of the Second Expansion.

I reached out to it.

The book opened itself. Pages flipped wildly. Eyes, thousands of eyes stared at me from the paper. "YOU ARE NOT WORTHY," a voice boomed in my head. Psychic damage, massive spike.

My nose started bleeding.

[Mental Defense Check...]

[Fail.]

[HP: -100.]

My vision blurred.

"Shut up," I snarled.

I slammed my Void Ring onto the open page. I wasn’t reading it. Instead, I was Devouring it. "GLUTTONY!"

WOOSH.

The book shrieked.

The black ink lifted off the pages. It swirled into a vortex, then sucked directly into the gemstone on my ring. "No! No! I am Eternal! I am—"

SLURP.

The book on the pedestal turned into white, blank ash.

My ring burned. It turned from black to a deep pulsating violet.

[Ring of the Void Monarch: Level Up!]

[Tier 3 Unlocked.]

[New Passive Acquired: ’Mind of the Abyss’.]

(You are immune to Fear, Insanity, and Mind Control. Your thoughts are hidden.)

[New Active Skill Acquired: ’System Override’ (Alpha Version).]

(You can rewrite the properties of an object.)

I fell to my knees while laughing maniacally.

I stood up menacingly.

I looked at a rusty spoon sitting on a shelf.

"Override," I whispered.

[Target: Spoon.]

[Property Edit: ’Rust’ -> ’Sharpness’.]

The rust fell off indefinitely. The edge of the spoon shimmered with a reflective light. I touched it, it cut my finger. A razor-sharp spoon.

"This..." I grinned while wiping blood from my nose that was bleeding. "This is broken."

BOOM.

The alarm system was triggered out of nowhere. Red lights flashed and flickered.

[Security Breach Detected.]

[Sector Zero Locking Down.]

"Professor!" Dean Merlin’s voice came over the alarm intercom. "The Vault Guardian has awakened! You triggered the defensive mechanism!"

A golem formed from the surrounding books. It was thirty feet tall, made of paper and pissed.

[Boss: The Librarian]

[Level: 45]

It raised a fist made of Encyclopedias. "SILENCE IN THE LIBRARY," it roared.

I looked at the Golem.

I looked at my razor-sharp spoon.

"No," I said.

I activated my new Void Walk. I didn’t fight. I simply stepped through the space. I appeared outside the door, right next to a terrified Dean Merlin.

SLAM.

The vault door sealed shut behind me, trapping the Golem inside.

"You..." Merlin stammered. "You survived? What did you take?"

"Just some light reading," I said while dusting off my hands.

I looked at Sylvia. She was waiting, eyes lowered, submissive.

I looked at Seraphina. She was healing a paper cut on her finger.

"Pack your bags," I said.

"Class trip?" Seraphina asked.

"No," I smiled. "We have visitors."

I pointed to the window.

Outside, above the Academy grounds, the sky was tearing open again.

But this time, it wasn’t monsters. It was Ships. Airships. Black sails. Skeletal designs. It was the Necromancer Ship.

"Are we going to save the students?" Sylvia asked, her voice trembling.

I laughed. "Save them?"

I pulled out my calculator (System Interface). "The Necromancers drop ’Soul Stones’. Each stone sells for 10,000 Gold."

I drew the Soul-Eater’s Fang. "We aren’t saving anyone. We are Farming."

————————————————————

The lead Airship lowered a ramp. A figure menacingly stepped out. It was a Lich wearing a business suit.

"Greetings," the Lich announced. "We are looking for a thief named Cain Cross. He stole our Crown. Is he here?"
