The Harvester felt Nil before Jinsu saw the effect.
The person-shaped hole in the rendering — which had been moving at its unhurried walking pace through Sector 6's commercial district, consuming everything within its radius at the patient rate of something that had never needed to hurry — stopped.
Not because it had been struck.
Because it had felt something it recognized.
Harvest frequency.
Coming from inside the city's infrastructure. From below it. From the specific, distributed architecture of something that had been built from Harvest data and had been interfacing with that data for three days and had learned, in three days, to use that frequency the way a key learns the specific shape of a lock.
The Harvester oriented toward Nil.
Not toward Sector 4 specifically — toward the frequency. The way a magnet orients toward iron. The way consumption orients toward what can be consumed.
The person-shaped hole began moving toward the basement.
"It's working," Soo-yeon said. She was reading the movement through the city's street patterns — not with Eyes of the Architect, with the specific, tactical spatial intelligence of an A-Rank archer who had been learning to read urban combat geometry for months. "It's moving toward Nil."
"Yes," Jinsu said.
"That's not—" She looked at him. "That's not safer for Nil."
"No," Jinsu said.
She looked at him.
He looked at the person-shaped hole moving toward Sector 4.
He thought about the rooftop. About rather than the point. About let me protect it.
He looked at his team.
"We buy Nil time," Jinsu said. "Every second we can delay the Harvester reaching Sector 4 is a second Nil has to prepare the interface."
"How do we delay something we can't hit," Park said.
"Soo-yeon can hit it," Jinsu said. "Four percent. We need the Harvester to register something that demands its attention more than the Harvest frequency. Something that disrupts its consumption process enough to slow the orientation."
He looked at Soo-yeon.
She looked at her remaining four void-frequency rounds.
"Four rounds," she said. "Four percent each. That's sixteen percent of disruption spread across four shots."
"Sixteen percent of its attention," Jinsu said. "At the right moment. In the right sequence."
She looked at him.
"You're going to need to tell me the right moment," she said.
"I know," Jinsu said. "Trust me."
She looked at him for exactly one second.
Then she notched the first round.
The sequence that followed lasted eight minutes and forty-three seconds.
Not forty-seven seconds like Round One.
Eight minutes and forty-three seconds of the entire team working at maximum capacity against something they couldn't damage, couldn't stop, couldn't engage in any conventional tactical sense — but could redirect. Could slow. Could introduce variables into its consumption process that required it to reorient between each one.
Soo-yeon fired the first round at the Harvester's left flank — not aimed at the absence, aimed at the mana density in the air immediately adjacent to it, the void-frequency round detonating in the consumption field and introducing a frequency interference that the Harvester's consumption process registered as requiring resolution.
It reoriented toward the interference.
Six seconds of reorientation.
Six seconds of the person-shaped hole not moving toward Sector 4.
Sang-min used those six seconds to engage — not with strikes, with presence. He positioned himself between the Harvester and Sector 4 and blazed at full output, 4.2 million units creating the largest mana signature in the city's immediate architecture, the specific, irresistible draw of an enormous cultivation blazing in the Harvester's perception.
The Harvester oriented toward Sang-min.
Away from Sector 4.
Twenty seconds.
Then it recognized the pattern — the specific, systematic redirection — and reoriented back toward the Harvest frequency in the basement.
Soo-yeon fired the second round.
This time aimed differently — not at the adjacent consumption field but at the path between the Harvester and Sector 4. At the mana density in the air along the trajectory. The void-frequency creating a corridor of interference that the Harvester's consumption process had to navigate rather than move through directly.
Eleven seconds of navigation.
Park Jin-wook engaged during those eleven seconds — not direct combat, the geometry of his A-Rank Vanguard capability applied to mana field disruption. He used his own capacity output not as an attack but as a field — creating a specific mana pressure pattern that interfered with the Harvester's consumption radius, forcing it to manage the interference before it could resume orientation.
Seventeen seconds.
The Harvester managed the interference.
Reoriented.
Moved toward Sector 4.
Soo-yeon fired the third round.
Two remaining.
Jinsu used Void-Step to position himself directly in the Harvester's path.
[Void-Step: -1% Stability]
[Stability: 56.3% → 55.3%]
He activated Eyes of the Architect at full output and pushed the broadcast — not at the team, not at the civilians. At the Harvester's absence. Pushing visual data into the space where the rendering couldn't represent anything, trying to introduce a signal frequency that the Harvester's above-framework architecture had to process.
[Eyes of the Architect: Broadcast into absence]
[Target unrepresentable — output redirecting to adjacent architecture]
[Unintended effect: System nodes in 47-meter radius receiving broadcast data]
The System's nodes within the broadcast range received the Eyes of the Architect's output directly — raw, root-level perception data flooding into the compliance monitoring architecture of every streetlight and scanner and optimization node in a forty-seven meter radius.
The System's architecture stuttered.
Not the Harvester. The System itself.
The compliance bars above every person in the radius flickered — not back to their real values, but off. For 0.7 seconds the compliance monitoring in the forty-seven meter radius went dark as the System's local nodes tried to process raw root-level data they weren't designed to receive.
In those 0.7 seconds the mana density in the radius stopped falling.
Because the consumption field was driven by the System's compliance architecture. The System's submission to the Harvester's above-hierarchy presence was what amplified the consumption field.
When the compliance architecture flickered off — even for 0.7 seconds — the consumption field reduced.
Jinsu watched the mana density at 16%.
For 0.7 seconds it held at 16%.
Then the compliance architecture reestablished and the consumption resumed.
But Jinsu had felt the 0.7 seconds.
He had felt the consumption field reduce.
He had felt the Harvester's above-hierarchy presence — which existed above the System — suddenly operating in a space where the System's submission to it had momentarily stopped.
He filed it.
Not the Engine. Him.
Han Jinsu filing something that the Engine hadn't calculated yet.
The consumption field runs on the System's compliance, he thought. The Harvester doesn't consume directly. It consumes through the System's submission to its authority. When the System stops submitting — even for 0.7 seconds — the consumption field reduces.
He looked at the forty-seven constructs in the Buffer Zone.
The army.
Not weapons against the Harvester. The Engine had assessed them at zero effectiveness — void data against above-framework presence.
But the constructs were void data.
And void data — when broadcast directly into the System's compliance architecture the way Eyes of the Architect had just done — caused the System's nodes to stutter.
The System's nodes stuttering reduced the compliance submission.
The compliance submission reduction reduced the consumption field.
47 constructs broadcast simultaneously through the System's compliance architecture—
He did the calculation.
[Estimated compliance submission reduction: 34%]
[Estimated consumption field reduction: 34%]
[Estimated effect on Harvester's consumption process: Insufficient to stop. Sufficient to disrupt for an estimated 4-6 minutes.]
Four to six minutes.
The time it would take Nil to complete the interface.
He looked at Soo-yeon.
One round remaining.
"Save it," he said. "I have something else."
He closed his eyes.
He sent the Void Call — not to deploy the constructs physically, to broadcast them. Through the city's logic lines. Through the System's compliance architecture. Through every node and tether and monitoring protocol in the city.
Forty-seven frequencies. The specific void resonance of forty-seven deleted things broadcast simultaneously through the infrastructure of a System that had spent twenty-two years trying to erase what had produced them.
The System stuttered.
Not 0.7 seconds this time.
Four seconds.
The compliance bars above every person in Sector 6 flickered off simultaneously.
The consumption field dropped to 11% of its previous output.
The Harvester — which existed above the System but whose consumption field ran through the System's compliance submission — felt the reduction.
It stopped moving.
For the first time since it had entered the city three hours ago it stopped moving and reoriented toward the source of the interference.
Toward Zero.
Toward the thing broadcasting forty-seven void frequencies through the System's architecture simultaneously.
The mana density in the four-block radius — which had been falling since the Harvester arrived — stabilized at 16%.
For exactly four minutes and thirty-seven seconds it stabilized.
In the basement in Sector 4, Nil felt the consumption field reduce.
It felt the Harvester reorient toward Jinsu.
It felt four minutes and thirty-seven seconds of the Harvester's attention directed away from the Harvest frequency.
It used them.
