Yuna had been glancing at me sideways for the past ten minutes.
I got it. I really did. If I had watched someone die and then listened to them immediately start calculating their next death, I would have questions too. Probably several. Probably loud ones.
My questions were more practical.
Specifically: spike trap or fire vent, which one had the faster kill time?
It mattered. I was building a priority list. Fire probably had duration — the kind of death experience you remember afterward, assuming you came back to do remembering. Spikes were likely cleaner. Falling depended entirely on height. These were variables I needed to test.
I was twenty-three years old with an F rank class and seventy years of lifespan sitting in a system bank.
I intended to make deposits.
The trap appeared at the first junction past the Warchief's territory.
It wasn't subtle. A pressure plate, slightly different shade from the surrounding stone, centered perfectly on the fastest route forward. To the left, a narrow ledge wrapped around a pit — single file, careful footing, thirty minutes minimum to clear safely.
Every climber ahead of us had taken the ledge. Obviously. Sensibly.
I stopped walking.
Yuna stopped beside me automatically, then followed my eyeline to the pressure plate, then looked at me with an expression that suggested she already knew she wasn't going to like whatever came next.
"Why," she said carefully, "are you looking at the death trap like it insulted your family?"
"It's standing between me and information."
The plate was mechanical. Spring-loaded from the look of it, pressure threshold probably calibrated for an average adult's bodyweight. The other climbers had gone around it, which was the smart call, which was the reasonable call, which also told me exactly nothing about what it actually did.
If I stepped on it, I would know the trigger threshold. The projectile speed. The kill zone radius. The reset timer.
That was data. Real, usable, floor-relevant data that the ledge path couldn't give me.
I unclipped my knife and held it out to Yuna.
"Hold this."
"I will not—"
I stepped on the plate.
The spikes were faster than I expected.
That was my last thought before they arrived.
Cold stone. Cheek. The blank restart. Everything coming back online slowly like a bad connection finding its signal.
I pushed myself upright.
The notification was already there, waiting with the patience of a system that had all the time in the world.

I stared at the second box for a long moment.
A skill. The Tower had handed me a skill like a cashier sliding over a receipt. Thank you for your purchase. Here is your passive ability. Please come again.
I looked at the plate — reset, flush with the floor, innocent as a doormat — and felt something close to satisfaction settle in my chest. Spring mechanism faster than the design suggested. Kill zone roughly a meter and a half wide. Reset timer under sixty seconds.
I knew all of that now.
Because I had paid for it in the only currency this floor accepted.
The Tower rewards dying, I thought. Specifically. Deliberately. Like it was designed this way.
I filed that under: important.
***
Yuna was exactly where I had left her.
First death, she had looked at me like someone watching physics have a personal crisis. Horror. Disbelief. The expression of a person whose understanding of the world had been revised without their consent.
This time was different.
This time she was thinking.
"You got a skill," she said.
"Trap Sense. Two meter radius, passive detection."
She looked at the ledge path. The last few climbers were still shuffling through single file, taking every careful step like the floor personally hated them. Thirty minutes of shuffling to avoid forty-five seconds of dying.
"How many deaths," she said, voice completely level, "until you have full trap coverage for a floor?"
I stared at her.
She stared back. It was the tone of someone doing inventory.
"I don't have enough data yet," I said.
"Then you need a sample size." She sat down cross-legged on the stone floor, pulled a small notebook and mechanical pencil from her pack, and flipped it open to the first page with the efficiency of someone who had already made a decision. "I'll track the results."
"You're not going to argue with me about this?"
"You already died twice and you have clearly decided to keep going regardless of my opinion." She wrote something at the top of the page without looking up. "I would rather have documentation."
She turned the notebook toward me.
[NAME]'S DEATHS — ONGOING LOG
Two entries. Neat handwriting. Every column filled in.
Death #1 — Goblin Warchief, blunt trauma — Revived — Skill: none — +10yrs
Notes: Unsolicited. Heroic in motivation. MC was clearly surprised by own survival.
Death #2 — Spike trap, mechanical — Revived — Skill: Trap Sense F rank — +10yrs
Notes: Deliberate. Possibly insane. Possibly not.
"You left my name blank," I said.
"I don't know it."
"Kai."
She scratched it in. Underlined it once.
Something settled in my chest that I hadn't been expecting. Something that felt like relief, which was a strange thing to feel after two deaths in the same afternoon. But there it was.
"Thank you," I said.
"Don't." She capped the pencil. "This is pure self-interest. If you're going to keep dying on purpose someone needs to be recording what it actually accomplishes."
She stood up, brushed the stone dust off her jacket, and nodded at the corridor ahead.
"What's next on the list?"
I almost smiled.
Three corridors later: the fire vent.
A grate in the floor. Periodic bursts on a cycle. I crouched at the edge and counted three full intervals — twelve seconds between each activation — before I confirmed the timing was consistent.
Yuna sat against the wall. Notebook open. Pencil uncapped. Expression professionally blank.
"Twelve second cycle," I said. "I go in on the off-interval and wait."
"Noted," she said, already writing.
I stepped onto the grate during the window and stood there.
Yuna counted quietly behind me. "...ten. Eleven. Twelve—"
I'll be honest about something.
The spike trap had been fast. A hard interrupt between one moment and the next, nothing drawn out, no time to experience anything except the impact.
Fire was not like that.
Fire had duration.
I'm not going to describe it in detail because there's no useful reason to, but when I came back — cold stone, blank restart, slow reload — my hands were shaking when I pushed myself upright. Not badly. Not visibly, if you weren't looking for it.
Yuna was looking for it.
I checked the notification before she could say anything.

Pain Tolerance.
The Tower had acknowledged, in its own bureaucratic way, that dying repeatedly hurt, and had responded by making it hurt approximately five percent less next time.
I appreciated the acknowledgment.
I had complicated feelings about the implementation.
Yuna was writing. She finished the entry before she looked at me. Then she looked at my hands.
She didn't say anything about them.
I appreciated that more than I had words for.
We caught up with the main group at the next junction.
About twenty climbers had made camp there — resting, eating, watching a monster patrol cycle from a distance that felt safe enough. Several heads turned when we arrived. Several looks stayed longer than comfortable, doing the math on two people who had clearly come through the fire vent corridor rather than around it.
A climber walked over. Broad. Warrior class. Late thirties, the look of someone who had spent his whole life calculating risk tolerance and had not, until today, encountered variables that didn't fit his existing models.
"You're the one who died to the Warchief," he said.
"That was death one," I said. "Three total today. Last two were research."
He looked at me. Then at Yuna, who showed him nothing. Then back at me.
The expression on his face existed somewhere between suspicion, confusion, and something that didn't have a clean name but felt adjacent to calculation.
"What class?"
"Survivor."
He walked away without another word.
I chose to interpret this as the beginning of a reputation.
Yuna wrote something in the notebook. I didn't ask what.
The safe zone at the end of the corridor was a wide circular chamber — smooth walls, soft blue light from somewhere in the ceiling, sixty-odd climbers spread across the floor in the careful spacing of people who didn't trust each other but had accepted the necessity of proximity.
Yuna and I found a corner.
She opened the notebook. I worked through one of my remaining protein bars and read over her shoulder.
Three death entries. Skills listed and ranked. Lifespan totals tracked to the year. Projection notes sketched along the bottom margin in handwriting so small it was almost a code.
"At ten years per death," she said, "assuming skill unlocks continue scaling consistently — which is still an assumption — the efficiency curve gets significantly steeper in the early floors."
"The skills matter more than the lifespan," I said.
"I know. I'm modeling both separately." She tapped the pencil against the page, not writing, just thinking. "If you average twenty deaths per floor—"
"Yuna."
"What?"
"That's a lot of dying."
"I'm aware." She didn't look up from the notebook. "I have a whole column for it."
Then she put the pencil down and looked at me directly. Full attention. The kind that was harder to sit under than it looked.
"Are you okay?"
I thought about it. Not fast. Honestly.
Death one sitting heavy behind my eyes, blunt and solid. Death two, cold and fast. Death three parked in my peripheral vision where I was keeping it for now because looking at it directly wasn't something I was ready to do yet.
"I will be," I said. "Eventually."
She held the look.
"That's not the same as okay," she said.
"No," I agreed. "It's not."
She picked the pencil back up.
We sat in the quiet after that. The chamber murmured around us — low conversations, someone laughing too loud on the other side of the room, the distant chime of other people's system notifications doing their accounting. Somewhere across the room the Flame Emperor was holding court, a small crowd already orbiting him like he was a sun that had just switched on.
I fell asleep before I meant to.
The notification woke me.
Not with sound. With light — the wrong color. System messages were white. Lifespan updates were blue. Skills were green.
This one was gold.
I sat up in the dark. Climbers breathing around me. Yuna asleep three feet away, notebook still open across her knee, pencil loose in her fingers.

I read it twice.
Then I thought about the notification from yesterday. The one with the flat bureaucratic chill of a system flagging something it hadn't been designed to expect.
Entities notified: 0.
Yesterday that number had been zero.
Zero had apparently become one overnight.
I stared at the ceiling — dark stone, featureless, indifferent — and thought about something that called itself a friend before we had been introduced. In my experience, things that volunteered the word friend before you met them had an agenda that the word was doing work to cover.
The gold light faded. A standard white notification replaced it, routine as a receipt.

Floors cleared: 0 of 1.
Three deaths, ninety years banked, three new passive skills, and I hadn't even finished the first floor yet. An unknown observer watching from somewhere in the upper levels. An observer ID the system had chosen to redact, which meant either the system was protecting the identity or the identity was something the system itself didn't fully understand.
Neither option was particularly comforting.
I lay back down on the stone floor and closed my eyes.
Day two tomorrow. One observer. Ninety years in the bank and a hundred floors of inventory left to work through.
The math still works, I told myself.
I wasn't sure yet if the math was the whole story.
I suspected, the way you suspect things after a full afternoon of dying for data, that it probably wasn't.
