The goblin warrior collapsed first.
Its axe slipped from its grip, hitting the ground with a dull thud as its massive body followed moments later. The force of the fall shook the forest floor slightly before everything went still.
At almost the same time
My vision went dark.
I didn't even feel myself fall.
One moment, I was standing watching the monster crumple, and the next, my knees gave out. The world tilted violently before my back hit the ground.
Cold.
That was the first thing I noticed.
Cold earth pressed against my spine as I lay there, staring blankly at the canopy above. The leaves swayed gently, sunlight filtering through in broken patterns.
My chest rose and fell unevenly.
My limbs felt heavy.
"…Mana… drained," I whispered hoarsely.
Not empty.
But stretched thin.
I could still feel my mana vast, deep, unmoving, but the pathways that carried it burned faintly, as if overworked. Casting Crystal Spear at the very end, on top of everything else, had pushed my control beyond its limit.
My body paid the price.
I tried to lift my arm.
It trembled.
I let it fall back down.
"…So this is backlash," I muttered.
Not damage.
Not injury.
Just exhaustion so deep it weighed on my bones.
For a while, I didn't move.
I focused on breathing.
Slow.
Steady.
In through the nose.
Out through the mouth.
The book had mentioned that this mana recovery wasn't just about resting the body, but letting mana circulate naturally instead of forcing it through spells.
Gradually, the burning sensation faded.
Strength returned in fragments.
First to my fingers.
Then my arms.
Then my legs.
I don't know how much time passed. Minutes. Maybe longer.
When I finally pushed myself upright, the world no longer spun.
The goblin warrior still lay where it had fallen.
Not moving.
Not breathing.
"…I really did it," I murmured.
The realization settled slowly, heavily.
I hadn't won cleanly.
I hadn't won easily.
But I survived.
Using a nearby tree for support, I stood fully and steadied myself. My mana was recovering slowly, naturally. Still not enough for heavy spells, but enough to move.
Enough to think.
Enough to act.
I approached the goblin warrior cautiously.
This wasn't like the smaller goblins. Those encounters had been quick, almost mechanical. Traps, spells, retreat, repeat. I had kept my distance. Kept my emotions out of it.
This was different.
This one had looked at me.
It had thought.
It had adapted.
And I had killed it.
My legs finally gave out.
I stumbled backward and caught myself against a tree, pressing my palm into the rough bark as I tried to steady my breathing. My mana pool was still far from empty. I could feel it, deep within me, calm and vast.
But my body was exhausted.
Not from lack of mana.
From tension.
From fear.
From pushing myself past hesitation.
Crystal Spear.
I looked down at my hand.
That spell wasn't something I could cast casually.
Crystal Needle was simple thin constructs, fast formation, low structural demand. Crystal Spear was different. It required density. Compression. Precision. One mistake in the formation, and it would collapse before impact.
I had only succeeded because I stopped thinking.
Because I had to.
"…That was reckless," I whispered.
But it worked.
Slowly, I pushed myself upright and scanned the surroundings again.
Silence.
No movement.
No goblins charging in.
No ambush waiting to happen.
The remnants of the camp lay scattered around me broken tents, extinguished fires, crude wooden stakes snapped or knocked aside. The smaller goblins I had dealt with earlier were gone. Dead or fled.
Only the goblin warrior remained.
I approached it cautiously.
Up close, it looked even larger than before. Its armor was crude but layered, reinforced with bones and metal scraps. Its greenish skin was thick, scarred in multiple places.
A veteran.
A leader.
I crouched beside the corpse, keeping my distance at first. Monsters sometimes twitched after death, residual mana discharge, muscle spasms, or worse.
Nothing happened.
After a few seconds, I leaned closer.
That was when I noticed it.
A faint glow from within its shattered chest.
"…Huh?"
Carefully, I pulled aside torn flesh and broken armor.
Nestled between fractured ribs was a small, cloudy crystal about the size of a marble, dull in color, with faint veins of light pulsing inside.
Mana.
Condensed.
My breath hitched.
"…A mana core."
I had read about them.
Not all monsters had them. Most low-tier ones didn't. Mana needed time, pressure, and constant circulation to condense like this. That usually meant stronger monsters. Bosses. Alpha variants.
So this thing really was one.
I gently removed the core from the body.
It was warm to the touch.
Not burning, just… active. Like it was still holding onto the monster's last traces of life.
Low Grade.
Even without proper knowledge, I could tell. The core was cloudy, uneven, and lacking the clarity described in higher-grade ones.
But still…
This was valuable.
I wrapped it carefully in cloth and placed it inside my bag, securing it as best I could. Only then did I allow myself to relax just a little.
And that's when the tremors started.
My hands shook violently.
My shoulders felt heavy.
My vision blurred for a moment as the adrenaline finally drained away.
I lowered myself to the ground and sat with my back against a tree, closing my eyes.
"…I nearly died."
That thought came unbidden.
If the crystal spear had failed…
If my timing had been off…
If my control had slipped for even a moment…
My mana pool was large unnaturally so. I knew that much. I could cast more spells than most beginners without exhausting myself.
But raw capacity didn't mean mastery.
Spells like Crystal Spear demanded structure, not just mana. They punished hesitation. Punished inefficiency.
Today proved that clearly.
I stayed there for a long while, resting, letting my breathing slow, letting my mana circulate naturally through my body.
Only when the sun dipped lower did I finally stand.
By the time I returned to Water Ridge, dusk had settled in.
My clothes were filthy. Dirt clung to my sleeves. Dried blood stained the edges of my shirt and boots. My muscles ached with every step.
I went straight to the inn.
The moment I stepped inside, the warmth and noise washed over me. Laughter. Clinking dishes. The smell of cooked food.
Normal life.
The innkeeper glanced up and frowned.
"…Rough day?"
"You could say that," I replied.
She didn't press further, just gestured toward the back. "There's water. Don't drip on the floor."
I nodded and made my way outside.
Once I was alone, I raised my hand and focused.
"Water Ball."
A sphere of clean water formed instantly in front of me, shimmering softly. With a small adjustment, I expanded it, letting it collapse over my body.
Cold water splashed over me, washing away dirt, sweat, and blood in one rush.
I summoned another.
Then another.
Simple spells. Minimal effort. Perfect control.
At least… these didn't fight me.
Once I was reasonably clean, I returned inside, ate quietly, and headed to my room.
The moment I closed the door behind me, my strength vanished.
I collapsed onto the bed and stared up at the ceiling.
The room was silent.
No goblins.
No forest.
No danger.
Only thoughts.
I pulled the mana core from my bag and held it above my chest.
Low Grade Mana Core.
It glowed faintly in the dim light.
"…So this is real," I murmured.
Today had changed something.
Before, everything felt theoretical. Spells. Monsters. Mana. Even death felt distant, like something that happened around me.
Not to me.
Not because of me.
Now?
I had killed a leader-class monster.
I had claimed a mana core.
I had crossed a line.
I rolled the core between my fingers.
This thing could be sold.
That was the logical choice. Money meant stability. Better food. Better equipment. Safer days.
But another thought lingered.
Power.
Not the reckless kind. Not charging into danger blindly.
Controlled power.
My mana pool was large, but inefficient. I relied on brute output instead of precision. Crystal Needle was easy. Water Ball was effortless.
But Crystal Spear?
That spell had pushed me.
It forced me to compress mana tighter than before. To shape it without excess. To focus.
If I wanted to survive in this world, that wasn't optional.
"…I need to get better," I whispered.
Not stronger.
Better.
I stared at the ceiling again, the events of the day replaying in my mind: the goblin warrior's charge, the desperation, the moment I abandoned hesitation and cast Crystal Spear.
Fear had sharpened my focus.
That wasn't sustainable.
Next time, I might not have that luxury.
Slowly, I closed my eyes.
Tomorrow, I will decide what to do with the core.
Tomorrow, I will plan my next steps.
But tonight…
Tonight, I needed to remember this feeling.
The weight of survival.
The cost of power.
And the truth is that this world would not forgive mistakes.
