Yandere Monster Evolution: My Blind Wife Will Become a Demonic Queen

"Teamwork," I smiled, lifting the heavy steel lid of the chest.

Inside, resting on a cushion of dark black velvet, was the Crimson Heart.

It was stunning. A brilliant, fist-sized blood-red mana crystal was embedded in an antique silver casing shaped like a sleeping dragon. The crystal pulsed with a slow, warm light, radiating a dense, high-tier mana that made the skin on my arms tingle.

"Fifty million credits..." I muttered, carefully reaching down and lifting the heavy silver casing from the velvet cushion. "Vane wasn’t lying about its value. The mana density in this crystal is insane."

Carmilla looked down at the silver dragon casing, a soft, peaceful expression touching her face. "That seal... it belonged to the House of Blood Crest. This was my grandfather’s personal pocket crystal."

I stopped, looking up at her with the relic held tightly in my hands. "Carmilla... if this belongs to your family lineage, I can’t just hand it over to a shady syndicate manager like Vane. We can take it home."

Carmilla looked at me, and then at the glowing red crystal. She slowly shook her head, a gentle, genuine smile breaking across her lips under her mask.

"No, Woo Jin," Carmilla said firmly. "The past is gone. That stone castle is dust, and my family is at peace. Right now, you are building your strength to protect Viora, Leo, Mia, and me. We need Vane’s trust, and we need access the network. Handing this to Vane serves our future."

I looked into her dark red eyes, moved by her maturity and selflessness.

"Thank you, Carmilla," I said quietly, wrapping the silver relic in a thick cloth and stowing it securely inside my leather jacket pocket. "I’ll make sure this trade buys us the exact information we need."

"Now," Carmilla said, adjusting her beanie. "Let us head back. I do not want to keep Viora waiting for dinner."

We turned around and walked out of the room, heading back through the grand hall toward the fortress exit.

As we stepped out of the heavy iron gates back onto the open stone plaza, the sun had fully set behind the horizon. The bruised purple sky of Sector B-4 had turned into a pitch-black night, illuminated only by the faint, eerie glow of burning grey embers floating in the cold wind.

Suddenly, my ears twitched.

The sound of soft, heavy boots stepping on ash echoed from the shadows of three surrounding stone pillars.

"Stop right there, rookies," a cold, mocking voice called out from the darkness.

I paused instantly, placing my right hand over my jacket pocket where the relic was stored. Carmilla slid her right hand smoothly toward her hidden waist strap, her body dropping into a low, predatory stance.

Three figures slowly stepped out into the open plaza, surrounding us in a tight triangle.

They weren’t wearing the rough leather gear of mercenaries. They were clad in matching dark-grey tactical suits, armed with high-grade mana rifles and enchanted steel short-swords. On the right shoulder plate of their tactical suits was a familiar dark emblem—a black shield with a broken sword.

It was an advance scout unit from The Black Faction’s main team.

The leader of the trio—a tall, scarred man with a robotic eye piece glowing green over his right eye—stepped forward, resting his heavy rifle against his shoulder.

"Manager Vane sent us to keep an eye on you two," the scout leader sneered, his voice raspy and arrogant. "He didn’t actually expect a low-rank kid and a quiet girl to survive Sector B-4. But look at that... you actually brought the silver casing out of the keep."

"We have a contract with Vane," I said coldly, keeping my voice deep under my mask. "Step aside."

"Contract?" the scout leader laughed mockingly, his two squad mates chuckling along with him. "Kid, you’re in the gray zones now. Contracts are for people who survive. Hand over the package, and maybe we’ll let you two walk back to the fence with all your limbs."

I looked at the three armed scouts, then glanced sideways at Carmilla.

Carmilla’s dark red eyes were visible through the gap of her beanie. A tiny, dangerous spark of crimson lightning flickered around her fingertips inside her hoodie pockets. She wasn’t scared at all; she was just waiting for my word.

’These guys think they’re hunting easy prey,’ I thought, my heart beating with a cold, steady rhythm. ’Time to show them why we finished the Pit in fourteen seconds.’

"Carmilla," I spoke softly under my mask.

"Yes, Woo Jin?"

"How many seconds should we give them?"

Carmilla’s lips curved into a small, confident grin under her dark shadow.

"Let’s make it ten," she said.

"Ten seconds it is," I murmured under my face mask.

Before the lead scout could even lift his plasma rifle, I didn’t rush forward. Instead, I grabbed two handfuls of fine grey ash from the ground and tossed them straight into the cold air.

SWOOSH!

A thick cloud of grey dust expanded between us, blocking their thermal sensors for just a split second.

"Fire!" the scout leader yelled.

RAT-AT-AT-AT!

Red plasma bolts tore through the grey cloud, blasting holes into the heavy volcanic stone wall behind us. Blue sparks and smoke filled the narrow entrance.

They were shooting at air.

Carmilla was already behind them. She had moved so fast that the heavy grey ash beneath her boots didn’t even shift. Her dark beanie stayed perfectly in place, and her black arming sword was drawn in a flash of dark steel.

THWIP-CRACKLE!

A blinding arc of red lightning burst from her blade, striking the scout on the far right directly in his back armor!

ZZZZZZZT-BOOM!

The electric shock fried his suit’s power core in half a second. The scout let out a muffled scream as his heavy armor locked up completely, sending him crashing face-first into the cold stone floorboards.

"Behind us!" the second scout barked, turning his plasma rifle toward Carmilla.

He never got to pull the trigger.

I burst out of the grey dust cloud, keeping my body low to the ground. I closed the fifteen-foot gap instantly and drove my shoulder straight into his waist.

BANG!

The second scout stumbled backward, his plasma rifle flying out of his gloved hands. Before he could reach for the side-blade on his hip, I spun my iron dagger in my palm and slammed the heavy iron hilt straight into his helmet’s visor.

CRACK!

The reinforced glass shattered into a dozen tiny spiderwebs. The scout’s head snapped back hard, his eyes rolling into the back of his skull as he slumped limply against a crumbling stone pillar.

That left only the scout leader.

His green robotic eye flickered wildly as he realized both of his squad mates had been taken down in under eight seconds. Panic showed in his posture as he unslung a heavy mana grenade from his chest strap.

"You crazy kids—!" he shouted, pulling the safety pin.

"Too slow," Carmilla whispered right beside his ear.

Her voice was like an icy wind. Before the leader could toss the explosive, Carmilla brought the flat side of her black sword down in a lightning-fast vertical strike, hitting his wrist with terrifying force.

THWACK!

The scout leader let out a pained howl as his hand went completely numb. The live mana grenade dropped from his fingers, rolling across the dusty floor.

I lunged forward, kicking the live grenade like a soccer ball straight out the open iron gates into the empty wasteland outside!

BOOM!

A heavy explosion shook the ground outside, sending a shower of grey ash and loose pebbles raining down over the fortress entrance.

Carmilla didn’t hesitate. She stepped inside the scout leader’s guard, delivered a sharp knee strike straight into his stomach armor, and followed it up with a smooth elbow smash to his jaw.

THUD!

The lead scout collapsed heavily onto his back, his robotic eyepiece blinking out as he went stone-cold unconscious.

I stood up straight, taking a deep breath of air as the dust slowly settled down. I checked the iron watch on my left wrist.

"Twelve seconds," I noted, sheathing my dagger back into my lower belt. "A little over our guess, but pretty close."

Carmilla wiped a faint speck of dust from her sleeve, slipping her black blade back into the cloth. She pulled her dark sunglasses back over her red eyes with a small, satisfied nod.

"They talked too much," Carmilla said simply. "Humans in armor always rely too heavily on their weapons."

"That’s why sensory training matters," I smiled, patting my jacket pocket to make sure the velvet box containing the Crimson Heart was completely safe and untouched. "Let’s loot their spare mana batteries and head for the fence before more scouts show up."

We quickly checked the unconscious scouts, taking their encrypted radio unit so I could listen in on their private frequencies later. Once we had everything, we left the ruined stone fortress behind and began our fast walk back toward the perimeter line.

The walk through Sector B-4 was quiet now. The remaining Ash Stalkers in the area seemed to have smelled the fresh blood and loud explosions near the keep, choosing to stay deep inside the dark shadows of the broken skyscrapers.

By 7:00 PM, the thick grey fog began to thin out, and the massive rusted perimeter fence appeared in front of us.

The black transport van was still sitting right where we had left it, its engine idling softly in the damp cold.

The scarred old driver was leaning against his front door, smoking a cheap cigarette. When he heard our heavy boots stepping through the broken gate, he turned his head casually—and then froze. His cigarette slipped right out of his fingers, landing in the damp grass.

He stared at us with wide, disbelieving eyes.

"You two... actually walked back out?" the driver stammered, looking past us into the pitch-black wasteland of Sector B-4. "Where are the scouts? Where’s the rest of the team?"

"We finished the job," I said plainly, pulling open the slide door of the van. "Drive us back to the eastern hub. Manager Vane is waiting."
