The Blind SSS-Class Final Boss Is Obsessed With Me

Chapter 14: Core Room

Soon, after steadying his breath, Principal Valerius stood up from the floor. He looked incredibly pale, but he didn’t say another word. He simply turned around and began leading us toward the core room.

Following him, we walked past the trembling staff members who watched us with wide, terrified eyes. Nonetheless, nobody dared to speak.

Valerius led us deep into the back of the building, down a flight of cold stone stairs to the basement level.

At the end of the dark corridor, a massive circular door made of solid mythril stood high. It was carved with ancient, glowing blue runes that were now flickering violently.

"I can open it," Valerius said, his voice shaking slightly as he stared at the glowing metal. "But the feedback is too strong. The mana... it’s screaming. If I try to force the seals now, the backflow of raw magic will vaporize whoever is standing in front of it."

I stared at the vibrating runes.

’Feedback?’

Of course the feedback was strong. I knew exactly why.

In the novel, this mythril door wasn’t just a physical barrier; it was a magical pressure valve connected directly to the Academy’s Core. Right now, the core was overflowing with unstable mana from the rifts. The door was trying to vent that excess energy, but the external rifts and the dungeons on the ground were pushing back.

If Valerius tried to use his solar mana to unlock it, the contrasting energies would clash, causing a massive explosion that would level the entire administrative block.

But I knew the system. I knew the design flaw the author had written into this seal.

"It’s screaming because you are trying to solve a flood by blocking the pipe, Valerius," I said calmly.

I walked right up to the massive door. The sheer pressure of the leaking mana made my skin crawl, but I didn’t back down. I pointed to three specific runes on the lower left quadrant of the circle.

"The resonance isn’t coming from the core itself. It’s coming from the secondary stabilization runes," I explained, looking over my shoulder at the stunned Principal. "They are trying to filter out the corrupted mana from the rifts, but they are overloaded. We don’t need to break the seal. We just need to overload the filter."

Valerius stared at me like I had grown a second head. "Overload it? Are you insane? That will destroy the entire runic circuit!"

"Exactly," I murmured.

I turned to Seraphina. She was standing right behind me, waiting.

"Seraphina," I said, my voice soft but clear. "Put your hand right here. On these three runes. Don’t use your destructive power. Just inject a tiny bit of your dark mana. Let it flow slowly, like water filling a cup, until the blue light turns black."

She didn’t answer. She simply stepped forward.

Her white robes trailed on the dusty floor as she placed her slender hand exactly where I had pointed.

Valerius held his breath, flinching as if expecting a massive explosion.

But there was no explosion.

Under my precise direction, Seraphina’s dark mana seeped into the blue runes. For a moment, the high-pitched humming grew louder. But then, right as the pressure reached its peak, the blue light suddenly turned a deep, obsidian black.

The chaotic, screaming mana instantly went dead silent.

The mythril, which had been hard as bedrock, began to soften. It flowed like liquid under her touch, melting away until the massive door simply dissolved into a dark, harmless mist.

Valerius gasped, his eyes nearly popping out of his head. "Impossible... that’s a Grade 9 seal... You bypassed it without triggering the defense mechanism..."

"I told you," I said, walking past him into the darkness. "You just need to know which strings to pull."

....

We stepped into the Core room.

In the center of the vast, circular chamber, suspended in a field of flickering magical energy, was the Academy Core. It was a massive crystal, the size of a carriage, pulsing with an erratic, unstable violet light.

It was the heart of the academy, and right now, it was dying. Large cracks were spreading across its surface, leaking pure magic into the room.

"It’s... it’s too late," Valerius whispered, collapsing to his knees. "The mana core is collapsing. Not even I can fix it. In less than ten minutes, it will detonate. We are all dead."

"It’s only too late if you don’t have a better power source," I said.

I looked at the massive, cracked crystal. If Seraphina just grabbed it blindly, her overwhelming dark mana would clash with the core’s neutral energy and cause a cataclysmic explosion.

I needed to guide her. I had to act as the bridge.

I walked up to the control pedestal in front of the core. The stone surface was covered in complex geometric lines. Using my knowledge from the novel, I quickly traced my finger along the ley lines, finding the manual override switch.

Click.

The glass cover over the primary node slid open.

"Seraphina, if you may, please," I called her and she walked toward the crystal. When she was close enough to the crystal, I continued. "Put your hand inside the primary node. Merge your mana with the core’s central artery. Hmmm... how do I explain it... Ah, Make it yours, yeah."

She did exactly as I asked. She reached out, and her fingers sank into the solid, pulsing surface of the crystal as if it were nothing but warm water.

The reaction was instantaneous.

A pillar of pitch-black light erupted from the Core, shooting violently upward through the high ceiling, piercing through the layers of the building, and straight into the sky.

The entire building shook with a massive, deafening boom.

Outside, I could hear the immediate, drastic change.

The chaotic, terrifying sounds of the monster invasion were suddenly muffled, cut off as if a giant hand had placed a cup over the campus. The air in the room, which had been thick with the smell of blood and burnt flesh, suddenly turned incredibly crisp, clean, and freezing cold.

’Did it work?’

I ran to the narrow slit of a window on the wall and looked out.

My breath hitched.

The golden dome of the academy was completely gone. In its place was a towering, impenetrable wall of dark barrier. The dungeons that had been opening within the campus grounds were suddenly snuffed out.

The monsters that had been roaming the campus, hunting down students, were suddenly frozen in place. Before they could even roar, their bodies rapidly turned into solid obsidian statues. A light breeze swept through the courtyard, and the statues shattered into harmless black dust which scattered in the wind.

The academy was no longer a bloody battlefield. It was a fortress.

I turned back to the room.

Seraphina was standing in front of the massive Core, which was now glowing with a beautiful, deep obsidian-violet hue. The cracks on its surface had healed completely.

She slowly turned her head toward me, and a small, haunting smile materialized on her pale lips.

"Cian..." she whispered, her voice echoing softly in the quiet room.

Ignoring the terrified Principal who was still huddled in the corner, staring at Seraphina as if she was god of destruction, I walked toward her.

I reached out and gently took her hand.

"We did it," I said softly.

"Yes..." Seraphina agreed, her fingers locking tightly with mine. "We... Did...."

I looked at her. I looked at the blindfold, the dark horns, and the feeling of obsession radiating from her.

Originally, I had just wanted to survive. I had wanted a weapon to protect myself from the impending doom of this apocalyptic world.

But as I stood there in the quiet of the fortified building, holding hands with the literal end of the world, I realized I had gotten something much more dangerous.

I had gotten a partner who would burn the entire world to the ground just to see me smile.

And as the violet sky burned harmlessly outside our black crystal walls, I realized that I was perfectly okay with that.

The original story was officially derailed. The Hero was practically gone. The old world was dead.

The Final Boss was deeply obsessed with me for some unknown reason I had yet to figure out.

And to be honest, I couldn’t have written a better script myself.
