Taeyang spent three days recovering from the Drowned Vault.
His body healed faster than it should have — a side effect of the System, which accelerated hunter recovery rates to keep them combat-ready. But the psychological damage lingered. He kept waking at 3 AM, gasping for air that wasn't there, feeling phantom pressure crushing his chest.
On the fourth day, he made a mistake.
The mistake was called "Rapid Farming."
Ghost had sent him information about a farming technique some underground hunters used. Enter multiple low-rank dungeons in rapid succession, clearing them with minimal effort, stacking loot bonuses that accumulated across runs. The key was speed — the System tracked dungeon completions over rolling 24-hour periods, and hunters who cleared five or more dungeons within that window received escalating rewards.
Five dungeons. Taeyang had cleared three C-ranks and two D-ranks in the past two days without issue. His SIP regenerated between runs. His ability handled each dungeon comfortably. The math seemed simple.
What he forgot was that SIP regeneration had a hidden variable: diminishing returns based on activity level.
After his fifth dungeon — an easy D-rank called "Spider Warren" that he cleared in twelve minutes — his SIP gauge showed something disturbing:
**[System Integrity: 100/100 → Maximum Regeneration Rate: 45%]**
He'd pushed too hard. The System had throttled his regeneration. His SIP cap was still 100, but he could only recover 45% of it between runs — 45 points maximum until the throttle reset.
The smart move was to stop. Wait 24 hours for the throttle to lift. Accept the reduced loot and try again another day.
Taeyang didn't make the smart move.
A sixth dungeon had appeared in his rotation — a new C-rank called "Ironwood Grove" that Ghost's data hadn't covered. New dungeons meant fresh parameter sets. Fresh parameters meant potentially lower modification costs before the dynamic pricing adapted.
He entered with 45 SIP, confident that C-rank dungeons rarely required more than 30-40 points.
---
Ironwood Grove was not a normal C-rank.
The dungeon had formed in a corrupted section of forest that had been touched by the System's reality-warping effects. Trees that should have been organic had become iron — literally iron, their bark replaced with metal, their leaves with razor-sharp steel blades.
And the monsters weren't the usual variety.
```
[C-RANK DUNGEON: Ironwood Grove]
[Classification: NEWLY FORMED (less than 7 days old)]
[Monster Type: Ironwood Beasts (metal-organic hybrids, high defense)]
[Environmental Hazard: Iron Pollen (reduces ability effectiveness by 25%)]
[Boss: The Ironwood Heart (parameters unknown — new entity)]
```
Iron Pollen. Reduces ability effectiveness. His modifications would cost 25% more than expected.
And the boss had unknown parameters. New entity meant the System hadn't cataloged it yet — which meant Ghost's data couldn't help him.
He should have left. The exit was right behind him. But the loot bonus timer was ticking, and if he quit now, the entire day's farming would be wasted.
Pride. Greed. Impatience.
He stayed.
---
The first Ironwood Beast cost him 5 SIP to neutralize instead of the expected 3.
**[PARAMETER MODIFICATION DETECTED]**
**[Ironwood_Beast_01: Defense reduced by 50%]**
**[System Integrity Cost: 5 points (includes Iron Pollen penalty)]**
**[Remaining: 40/100]**
Still manageable. But the dungeon had more monsters than a typical C-rank. Ghost had mentioned that new dungeons tended to overcompensate — throwing extra resources at hunters to establish difficulty baselines before settling into patterns.
The second beast cost 5 more. Then the third. Then a group of four that he had to modify individually because environmental modifications couldn't affect their biological parameters.
**[Remaining: 20/100]**
By the time he reached the boss chamber, his gauge was nearly empty. Twenty points. That was enough for maybe four basic modifications — not nearly enough to handle an unknown boss.
The Ironwood Heart stood in the center of a clearing consumed by metal growth. It was massive — fifteen feet tall, shaped like a wolf if wolves were made of iron wood and hatred. Its eyes glowed with the same sickly light as the pollen drifting through the air.
```
[BOSS: The Ironwood Heart]
[HP: 120,000]
[Defense: Extremely High (metal-organic hybrid armor)]
[Damage: 600-900 (Physical/Piercing)]
[Special: Unknown (new entity — abilities not yet cataloged)]
```
Unknown specials. Defense so high that his knife would bounce off. HP that would take forever to whittle down even if he could damage it.
And he had 20 SIP.
Taeyang ran calculations. Defense reduction would cost at least 15 points with the Iron Pollen penalty. That left 5 for anything else — not enough to neutralize specials, not enough to reduce damage output, not enough for any safety margin.
The Ironwood Heart noticed him. Its metal head turned. Its iron eyes locked onto his position.
Fight or flee.
He had maybe three seconds to decide before it charged.
The exit was two floors behind him. He'd have to fight through at least six more Ironwood Beasts to reach it — beasts he couldn't afford to modify.
Stay and fight an unknown boss with insufficient resources. Or flee through enemies he also couldn't afford to fight.
Neither option was good.
The Heart charged.
---
Taeyang dodged the first attack by throwing himself sideways. The beast's iron claws carved trenches in the metal soil where he'd been standing.
He didn't try to modify it. Couldn't afford to. Instead, he ran — circling the clearing, staying ahead of jaws that could bite through steel.
Think. What are its specials? What can I predict about a new entity?
New dungeons. New monsters. New bosses. Ghost had said they overcompensated, threw extra resources at hunters. That usually meant—
The Heart's body split.
Two wolves now. Exact copies. Both charging from different angles.
**[IRONWOOD HEART: SPECIAL ABILITY — SPLIT]**
**[Effect: Divides HP and damage between copies. Can split up to 4 times.]**
Division. The boss could split into multiple versions of itself. That meant the HP wasn't just 120,000 — it was 120,000 spread across however many copies existed.
One became two. Two became four. The clearing filled with iron wolves, each smaller than the original but still lethal.
Taeyang used his SIP.
**[Ironwood_Heart (all copies): Movement Speed reduced by 60%]**
**[System Integrity Cost: 12 points (environmental modification, affects all)]**
**[Remaining: 8/100]**
The wolves slowed. Not stopped — slowed. Their legs moved through air that had become thick as water.
Eight SIP. One more modification at most. Then nothing.
He ran for the exit, dodging between slowed wolves, praying his reduced movement penalty was enough to outpace them.
It wasn't.
A wolf caught his leg. Iron teeth punched through armor, through flesh, into bone. Pain exploded up his body. He screamed, slashed at the wolf's face with his knife, felt the blade bounce off metal hide.
The wolf shook its head. His leg tore. Blood sprayed across iron leaves.
He spent his last SIP.
**[Ironwood_Heart (Copy_03): Jaw Strength reduced to 0]**
**[System Integrity Cost: 8 points]**
**[Remaining: 0/100]**
The wolf's grip loosened. Its jaw hung slack, muscles suddenly unable to generate force. Taeyang ripped his leg free and ran — stumbled — crawled toward the exit.
Zero SIP. No modifications possible. A leg that was bleeding out. Six floors of dungeon between him and escape.
The wolves followed, still slowed but still moving. He had maybe a minute before they caught him.
He ran anyway.
---
The next thirty minutes were the worst of his life.
He couldn't fight the Ironwood Beasts blocking his path. He could only dodge them — badly, with a leg that couldn't bear weight, leaving blood trails that made tracking trivial.
He fell three times. Got up three times. The fourth time, he couldn't get up.
A beast stood over him, metal claws raised.
This is it, Taeyang thought. This is how it ends.
The beast's claw came down.
An arrow punched through its eye, shattering the iron-organic hybrid brain behind it. The beast collapsed.
More arrows followed. A rapid barrage that dropped beasts left and right. Voices shouted in the distance — a hunting party, entering from the dungeon's second entrance.
"Survivor here! Wounded!"
Hands grabbed him. Faces blurred above. Someone was bandaging his leg. Someone else was feeding him a healing potion.
"You're lucky we were tracking this dungeon," a voice said. "New formations are priority for the underground network. Couldn't let a fresh dungeon go unmapped."
Taeyang tried to speak. Couldn't. His throat was too dry, his body too drained.
"Rest. We'll get you out."
He closed his eyes and let the darkness take him.
---
He woke in a safe house. Not his usual one — somewhere nicer, with actual beds and running water.
Ghost was there, sitting in a chair beside the bed, reading from a tablet.
"Forty-seven stitches," Ghost said without looking up. "Three broken bones. Blood loss that would have killed a normal human. You're an idiot, Breaker Boy."
"Aware." Taeyang's voice was a croak.
"The party that found you was one of mine. Information network has advantages beyond data — we look out for each other. Usually." Ghost set down the tablet. "You pushed too hard. Farming runs. Throttled regeneration. New dungeon with unknown parameters. Every mistake you could make, all at once."
"I know."
"Do you? Because the last time we talked, you were confident. Controlled. Smart about resource management." Ghost's expression was unreadable. "This wasn't smart. This was desperate. Something changed."
Taeyang thought about the hearing. The verdict. The feeling of walls closing in, of options disappearing.
"The Association is hunting me. The System is learning from me. My ability costs more every time I use it." He stared at the ceiling. "I thought if I pushed hard enough, fast enough, I could stay ahead. Build up resources before everything collapsed."
"And instead, you almost joined the deceased list."
"Yeah."
Ghost was quiet for a long moment.
"Recovery time is two weeks minimum. Your leg won't hold weight for at least that long. During that time, I suggest you think about what you're actually trying to accomplish." Ghost stood. "Power? Survival? Revenge against the Association? All of those require you to be alive. And alive means knowing when to stop."
He left without waiting for a response.
Taeyang lay in the bed, staring at nothing, feeling the throbbing pain in his leg and the deeper ache of having learned the same lesson twice in one week.
[Dungeon Break] wasn't enough.
Combat skills weren't enough.
Even Ghost's information network wasn't enough.
He needed something more. Something that would change the game entirely.
He just had to figure out what that was before the next mistake killed him.
