The flight back felt like drifting through a nightmare that wouldn't end. From the back of the Frost Phoenix, Seoul didn't look like a city anymore; it looked like a giant, dying animal. Thick, oily smoke choked the skyline, and the orange glow of fires reflected off the black, sluggish water of the Han River.
Every few seconds, a flash of light would burst from the streets below—someone's last stand, or maybe just another gas main giving up.
Behind me, the Weaver made a sickening, rhythmic click-clack sound. Her massive shadow-legs stabbed into the roofs of buildings as she leaped, her silk "cradle" holding fifty students who were too shocked to even cry. They just stared at the ruins of their world with hollow eyes. Their childhoods hadn't just ended; they had been incinerated.
"Lower," I rasped, my throat feeling like I'd swallowed glass.
The Phoenix tilted its wings. We dropped toward the rocky foothills on the edge of the city. This place was an old industrial quarry, a wasteland of jagged granite and rusted cranes that everyone had forgotten years ago. It was perfect.
When the Phoenix's obsidian claws hit the gravel, the impact rattled my teeth. I was beyond exhausted. My mana felt like a dry well, and every muscle in my body was screaming for me to just fall over and let the dark take me.
"Get off. Everyone, move to the cliff wall! Now!" I shouted.
The students scrambled out of the Weaver's silk and off the Phoenix. They huddled together, shivering in the biting cold. The temperature was still dropping—a nasty little souvenir from the Phoenix I'd just killed.
Lee Sung-min stepped forward, his wooden kendo stick chipped and stained with black monster blood. He looked at the sheer wall of rock in front of them, his breath coming out in frantic puffs of steam.
"There's nothing here, Han Chen," he whispered, his voice cracking with fear. "It's just a mountain. We're trapped."
I didn't bother answering. I walked to a rusted electrical box half-buried in the dirt, brushed away the grime, and pressed my palm against a smooth, black glass panel hidden underneath.
[Biometric Scan Initiated...] [Identity Confirmed: Han Chen.]
A deep, tectonic hum vibrated through my boots. It was the sound of massive hydraulic gears waking up after decades of sleep. With a hiss of air, a seam appeared in the granite cliff. A ten-ton slab of reinforced steel slowly slid back.
"Inside. Now," I said, not looking back. "The door stays open for sixty seconds. If you're still out here when the timer hits zero, you're just Orc food."
The students didn't need to be told twice. They surged forward, a mess of school uniforms and terrified faces, rushing into the warm, orange-lit tunnel. As the last student crossed the line, I felt that familiar, heavy gaze on my back. I didn't look up to find the Administrator's silver mask in the sky. I just stepped inside and let the door slam shut with a thunderous thud.
The silence was instant. The wind, the screams, and the smell of burning plastic were gone, replaced by the low hum of ventilation and the sterile scent of filtered air.
[You have entered a 'Level 1 Safe Zone'.] [Recovery Rate: +50%]
The tunnel opened into a massive underground hub. It was a masterpiece of survivalist paranoia—three levels of living quarters, medical bays, and even a hydroponic garden. This was the Iron Bunker, a billion-dollar tomb that I'd turned into a cradle for the future.
The students just collapsed. Some fell to their knees and wept, while others just sat in silence, staring at the clean, white floors. The jump from the hell outside to the safety inside was too much for them to process.
I walked to the center of the hall, my tattered raven-cloak dragging behind me like a shadow.
"Listen up!" I shouted. My voice bounced off the metal walls, sharp and unforgiving. "You're safe for now. But 'safe' is a temporary word. In five hours, the city outside will be flooded by the Third Wave. The things coming next make Orcs look like puppies. They're Demon Knights, and they'll find us eventually if we're weak."
I pointed at Sung-min. "Sung-min, you're the strongest here. Take five guys to Sector B. There are crates of riot gear and medicine. Organize it. If anyone tries to hoard food or refuses to help, tell me. I'll throw them back outside myself."
Sung-min didn't argue. He just nodded, his face hardening. He was growing up fast.
"Hana," I looked at the girl kneeling by a crate. She was still clutching that blue Phoenix Essence. It was glowing so brightly her skin looked translucent. "That orb is the only reason you're still breathing. You have five hours to make its power yours. Go to the meditation room in Sector C. Don't come out until you can freeze the air with a thought."
She looked up at me, her eyes full of a new, cold determination. "I won't fail."
I left them to it and headed to the very back of the facility—the Core Room. This was the heart of the bunker. I locked the heavy door and stood before a stone pedestal.
My heart was thumping against my ribs. Everything I'd done tonight—the high school, the Phoenix, the rescue—it was all for this. I reached into my cloak and pulled out the World-Tree Seed.
It was small, but it felt as heavy as a mountain in my hand. It pulsed with a gold light that felt like warm sunlight.
[Item: World-Tree Seed (Rank: SSS)] [Warning: Planting this will link your Soul to this location.] [Proceed?]
"Proceed," I whispered.
I placed the seed on the stone. For a long, agonizing second, nothing happened. Then, the stone cracked. A sprout as thin as a hair pushed through, glowing with a light so bright I had to look away.
Thick, white roots burst out of the pedestal like living snakes. They tore through the floor and wove themselves into the steel walls. I watched as the cold metal was slowly covered by glowing, white-gold wood. Emerald leaves sprouted from the ceiling, and the stale air suddenly tasted like a forest after rain.
[The 'Iron Bunker' has evolved into: 'The Yggdrasil Bastion'.] [Hidden Feature: Absolute Concealment Activated.]
I let out a long, shaky breath. We were hidden. For the first time in two lives, I felt like I could actually breathe. I slumped against the wall, my eyes drooping. I just needed a couple of hours...
But then, a notification box appeared. It wasn't blue. It wasn't even gold. It was a deep, bloody red.
[Warning: A 'Nameless Tracker' has detected a massive Mana Spike.] [An Elite Hunter has been dispatched to your location.] [Time until Arrival: 05:12:34]
I stared at the red box, my blood turning to ice. The Administrators weren't just following the script anymore; they were actively cheating to kill me. They were sending a specialized killer to find a "hidden" base.
I looked at the gold leaves above me, then at my own trembling, scarred hands.
"So that's how it is," I muttered, a dark, dangerous smile pulling at my lips. "You're so afraid of one guy that you're breaking your own rules?"
I didn't go to sleep. I stood up, gripped the hilt of my blade, and walked toward the training hall.
If a God's hunter was coming to my house, I was going to make sure he found a slaughterhouse instead.
