The Circuit's secondary venue was a converted water treatment facility in Tier 3's northern industrial sector.
The space was smaller than the primary venue — the fighting surface eight meters by eight instead of twelve, the observation seating reduced to twenty. Koren had relocated the operational infrastructure in under forty-eight hours. The console, the medical station, the data streams that represented her twelve-year intelligence operation — all functional in the new space.
"The Level Forty-seven," Cole said as the freight elevator descended. "Name's Davan Mercer. B-rank independent. Mana-suppression type."
"Suppression. Not reinforcement."
"Opposite end of the spectrum." Cole looked at the elevator ceiling. "Reinforcement adds mana to your own techniques. Suppression reduces the opponent's mana output. He generates a localized mana-dampening field during combat. Anything inside the field operates at reduced mana capacity."
"I have fourteen mana points. There's nothing to suppress."
"That's what I thought too." Cole scratched the tattoo. "Koren specifically chose this matchup. She said — and I'm quoting — 'the suppression field interacts with the Null Presence. I want to see how.'"
The Null Presence. Koren was testing his stealth ability. Not his combat — his passive. The thing that made him invisible to detection systems. The thing that had let him survive at Level Zero.
The freight elevator opened. The converted treatment facility smelled like chlorine and concrete. The fighting surface occupied what had been a settling pool — drained, lined with the same high-density polymer Koren used at all her venues.
Mercer was already on the surface. A lean man, early forties, with the contained intensity of someone whose combat style relied on controlling the environment rather than controlling the opponent. His mana output was steady and diffuse — not concentrated in his body like a reinforcement fighter but radiating outward, filling the space around him.
Shin's perception registered the field immediately.
It felt like fog. Not visual fog — a perceptive fog. His forty-point spatial awareness, which normally gave him a sixty-meter radius of detailed environmental data, contracted. Inside Mercer's field, the effective radius shrank. The data got fuzzy at the edges.
His perception was being suppressed.
"Begin," Koren said.
Mercer didn't advance. He stood at the surface's center and let the field expand. The suppression zone grew — five meters, seven, ten. The fighting surface was eight by eight. By ten meters, the entire surface was inside the field.
Shin's perception read at thirty-two instead of forty. Eight points suppressed. The spatial awareness was still functional but the resolution was reduced — the difference between a sharp image and one slightly out of focus.
He moved to test the field's limits. At the surface's edge, the suppression was lighter — thirty-six points of effective perception. At the center, near Mercer, it was heavier — twenty-eight.
A gradient field. Strongest at the source. The closer Shin got to Mercer, the more his perception degraded.
The combat implications were immediate. His fighting style relied on forty-point perception to predict opponent movement. At twenty-eight points, his prediction accuracy dropped. The model that had taken eighty strikes to calibrate against mana reinforcement was running on reduced data.
And there was something else.
The Null Presence was reacting.
The passive ability that made him invisible to detection systems — the thing that had been his survival mechanism since Level Zero — was interacting with the suppression field. Shin could feel it. Not pain, not disruption — interference. The Null Presence operated on mana. His fourteen points of mana sustained the passive. Mercer's suppression field was pressing on those fourteen points.
If the suppression reduced his mana below the threshold needed to sustain the Null Presence—
He moved toward Mercer to test it.
Twenty-eight effective perception. Twenty-five as he closed distance. The suppression pressing harder. His mana — he couldn't feel the number directly, but the Null Presence's operational status was something he'd monitored instinctively since Level Zero.
The passive flickered.
A half-second interruption. The Null Presence dropping offline and then re-engaging. Like a signal losing reception and reconnecting.
Mercer's eyes changed.
The suppression fighter had felt the flicker. His mana-dampening field was sensitive to the mana environment it operated in — when the Null Presence flickered, it produced a mana-signature pulse. A brief moment where Shin went from invisible to visible on mana-detection.
A ping. He'd pinged.
"There you are," Mercer said. Not aggressively. Clinically. The words of someone who was used to finding hidden things in his field.
Shin backed off. Distance reduced the suppression. At the surface's edge, his perception returned to thirty-six. The Null Presence stabilized.
The problem was clear. The closer he got to Mercer — close enough to strike — the more the suppression degraded his perception and threatened his passive. Fighting Mercer required closing distance. Closing distance meant operating at reduced capability with a flickering stealth ability.
Every tool he had was compromised inside the field.
Mercer came forward. Not fast — the suppression-type fighter's approach was methodical. He wasn't a speed fighter or a power fighter. He was a pressure fighter. The field did the work. The closer Mercer got, the more Shin's capabilities degraded.
Shin circled. Maintaining distance. The agility advantage kept him ahead of Mercer's advance, but the surface was only eight meters across. The geometric constraint limited evasion.
Mercer adjusted his field. The gradient shifted — heavier on Shin's right flank, lighter on the left. He was shaping the suppression zone to channel Shin's movement.
Tactical field manipulation. Mercer wasn't just suppressing — he was herding.
Shin moved left, into the lighter suppression. Mercer had anticipated this. The lighter zone was a corridor. At the corridor's end — the surface's corner. Boxed.
He recognized the trap at thirty-four effective perception. One second before the corner became terminal. He cut right, through the heavier suppression zone, and the perception dropped to twenty-six.
Mercer was there. Waiting.
The suppression fighter's physical stats weren't exceptional — B-rank average. Level Forty-seven meant approximately 470 total points, distributed across a conventional framework. In a straight fight without the field, Shin's agility and perception would dominate.
Inside the field, the advantage compressed.
Mercer's strike was a conventional straight right. No reinforcement — suppression fighters didn't reinforce. The strike was physical only. Shin's degraded perception read it at twenty-six-point accuracy.
He dodged. The margin was wider than the Voss fight — Mercer's physical speed was lower than a speed specialist's. But the reduced perception made the wider margin feel the same.
He countered. Straight right to Mercer's body. Twenty-six strength, no mana. The impact was clean.
Mercer absorbed it. The suppression fighter's endurance was average for his level, and the strike connected, but the effect was measured. Not the Voss fight's asymmetry — Mercer didn't hit harder because of mana. He just didn't get hit as effectively because the suppression degraded the attacker's combat pipeline.
Three exchanges. Four. Shin landing counters at reduced accuracy. Mercer absorbing them at standard endurance. The suppression field pressing continuously.
The Null Presence flickered again at the fourth exchange. Closer range. The suppression heavier. The fourteen mana points struggling to sustain the passive.
The flicker lasted a full second this time.
Mercer pivoted. The suppression fighter had been waiting for the flicker. During the second of mana-signature visibility, Mercer's field did something new — the suppression concentrated on the flickering point. A localized spike of mana dampening targeted directly at the Null Presence.
The passive dropped.
Completely.
For three seconds, Shin was visible. Not just physically visible — mana-visible. His entire stat profile, his mana signature, his combat readiness state — all of it readable to anyone with mana-detection capability.
Mercer saw it. Koren, at her console, saw it.
The Null Presence reasserted after three seconds. The fourteen mana points recovering from the spike, the passive re-engaging with the sluggish restart of a system that had been forced offline.
But the data was out. Three seconds of full mana-signature exposure. Whatever Mercer's suppression field had read during those three seconds was now part of the fight's intelligence.
Mercer came in hard. The methodical pressure abandoned for a committed advance. He'd seen something in the three-second window — something that changed his assessment.
"Your mana signature is wrong," Mercer said between strikes. Not taunting. Observing. "Fourteen points. But the architecture — the way the mana distributes through your system. It's not a fourteen-point architecture."
He didn't respond. He was too busy managing the suppression zone, the degraded perception, and the Null Presence's unstable recovery.
The fight continued for two more minutes. Mercer pressing. Shin surviving. The suppression field making every exchange harder than the raw stats warranted.
"Stop," Koren called.
---
"Point-three-one percent," Cole said. The towel. The edge of the surface. The routine becoming familiar.
46.11%. The day's C-rank grinding plus the fight.
Shin sat on the surface's edge and felt the Null Presence running at full capacity now that Mercer's field was deactivated. The passive hummed at the edge of his awareness — the fourteen mana points sustaining it, the signature suppression that made him nonexistent to detection systems.
Koren walked from the console.
"The Null Presence flickered twice and dropped once," she said. "Total exposure window: four-point-two seconds. During the exposure, your full mana signature was readable." She looked at her tablet. "The mana architecture Mercer identified — I want to discuss it."
"What about it."
"A Level One awakener with fourteen mana points should have a basic mana architecture. Linear distribution, no secondary structures, no complexity." She looked at him. "Your architecture has complexity. The Null Presence itself is an advanced passive ability that shouldn't be sustainable at fourteen points. The mana distribution shows secondary pathways that a fourteen-point pool shouldn't be able to maintain."
"Meaning."
"Meaning your mana system is running infrastructure that requires more power than you have. The fourteen points are sustaining something designed for a larger pool." She set the tablet down. "At Level Zero, you had zero mana and the Null Presence ran on — what? Nothing?"
"It ran on the zero state. The system classified me as nonexistent. The Null Presence was the system's expression of that classification."
"And at Level One, with fourteen mana points, the system is trying to convert the Null Presence from a classification artifact to a mana-sustained ability." She crossed her arms. "The conversion is incomplete. The infrastructure is there but the power supply is inadequate. That's why the suppression field destabilized it — Mercer's dampening reduced your already-insufficient mana pool below the threshold."
The Null Presence was running on fumes. Fourteen points sustaining an architecture built for a system that had classified him as nothing. The Level One transition had given him mana but hadn't given him enough to properly power the ability that had kept him alive.
"At Level Two," Shin said. "The mana pool increases."
"At Level Two, you'd have approximately 140 mana. Ten times the current pool." She looked at the venue's ceiling. "The Null Presence at 140 mana would be — significantly more robust. The suppression field that destabilized you tonight wouldn't touch it."
Level Two. Another thing waiting on the other side of the accumulation wall.
"The data from tonight," he said. "The mana architecture reading."
"Stays in my network." Koren turned back to the console. "Mercer is a professional. He doesn't discuss fight data outside the Circuit. But what he saw — the wrong architecture — he'll remember it."
One more piece of data in one more intelligence network. The Circuit's information ecosystem, trading in combat profiles and mana signatures and the operational secrets of everyone who stepped onto the surface.
Shin stood. The venue was emptying. The observers filing out through the treatment facility's service corridors.
"Koren."
She looked at him.
"The matchups. Voss tested my mana vulnerability. Foss tested my grapple defense. Mercer tested my Null Presence." He looked at her. "You're not matching me against opponents. You're matching me against my weaknesses."
"Every fight is a data point," she said. "For both of us."
He walked to the elevator with Cole. The converted treatment facility's chlorine smell followed them up.
"She's training you," Cole said in the elevator. "The matchups. She's not just collecting data — she's selecting opponents that force you to adapt."
"I know."
"You okay with that?"
The elevator doors opened. Night air. Industrial sector. Mira's transport two blocks north.
"The mana-suppression recalibration," Shin said. "Like the reinforcement recalibration. Each fight gives me a new dataset. Each dataset improves the prediction model."
"That's a yes."
"That's a yes."
They walked to the transport. Mira looked at him from the driver's seat. No visible injuries this time — the suppression fight was less physical than the Voss or Foss fights. But the exhaustion was different. Deeper. The Null Presence's three-second failure had drained something that physical combat didn't touch.
"Home," he said.
She drove.
The counter at 46.11%. The mana architecture's insufficient infrastructure. The Null Presence running on fumes. Level Two's 140-mana pool waiting on the other side of fifty-four more percentage points.
He closed his eyes and let the transport carry him and thought about fourteen mana points trying to power something that had been designed for a system that registered him as nothing.
Zero had been simple. Zero had been invisible. Level One had made him visible and given him just enough mana to pretend he wasn't.
Level Two would change the equation. If he could get there.
If.
