The wind kept moving after the case landed.
It followed them across the bridge and curled around the far receiver, dragging frost, broken labels, and old dust into a spinning ring. The six sweeping arms behind them kept moving in the same pattern, but now every pass fed the side vents harder.
The cables over the gap began to hum.
Ty kept his good shoulder against the case while the wheels settled into the far lock. The receiver had caught the front and rear guides, but the wind reached under the glass from behind and tried to pull the whole case back toward open air.
"The case is locked, but the wind is pulling against the lock," Ty said. "It feels like all six vents are still connected to the bridge."
JJ looked back at the spinning frost over the rails.
"Then the bridge is trying to reclaim its terrible property," she said. "I vote we make it deeply disappointed with us."
Blue dropped to one knee beside the far service plate, keeping both hands away from the receiver teeth. More lines had warmed into view under the title. The letters were small, cramped, and partly hidden under years of tool scratches.
"Whirl wind of Six is the first line here," Blue read. "Clear six motions before freight release from the bridge."
"Freight release means the case can leave this bridge?" Ty asked. "Please tell me the answer includes yes somewhere."
"Yes, after six motions clear and lock into place," Blue said. "The plate says each arm has to stop at its home slot before the receiver lets go."
Rusuf looked back across the bridge and listened.
All six arms swept in a circle now. One arm crossed, another followed before the first returned, and the vents pulled the air into a turning column above the gap. If the case had still been on the bridge, the wind would have lifted it sideways.
"The arms are chasing each other around the bridge," Rusuf said. "They will not home while the vents keep feeding the rotation."
"How do we stop six arms from overachieving?" JJ asked. "I assume asking them to value balance is useless."
Blue found six little shutter tabs along the far receiver, each one marked with a worn number. The tabs were arranged in a curve that matched the order of the arms.
"We close the vents in the same order the arms sweep," Blue said. "If one closes early, the wind shoves the next arm harder."
Ty felt the order through the frame, one, three, and five from the left, then two, four, and six from the right.
The same pattern as before, but faster now. The mark under his bandage pulsed when the first arm crossed. It pulsed again when the third arm followed. The room was giving him rhythm through pain, which was the kind of bargain he hated understanding.
"I can call the order through the frame," Ty said. "The mark is tracking each arm as it returns."
"Of course it is keeping attendance for machinery," JJ said. "Your hand has become a terrible foreman today."
Blue set Marcus’s bit against the first shutter tab.
"Call only when the arm is returning home," she said. "If I close during the sweep, the arm may slam."
Ty watched the bridge and counted the first sweep.
The first arm crossed from the left, cleared frost, and started back.
"One returning to the home slot now on the left," Ty said.
Blue pushed the first tab down with Marcus’s bit.
The leftmost vent snapped shut. The wind column staggered but kept turning. The first arm reached its slot and locked with a hard clack.
"One home and locked on the left side," Blue said. "Five bad choices remain after that first one."
The third arm crossed next from the left. It moved faster than before, pulled by the uneven wind. Rusuf stepped to the edge of the receiver and raised his sword.
"It is over-speeding on the return curve," he said. "Call late by half a beat for safety."
Ty waited through the worst of the sweep.
The third arm hit its return curve hard.
"Three returning now with the hinge still high," Ty said.
Blue shoved the third tab down and ducked back.
The vent closed. The arm slammed into its slot hard enough to shake frost from the bridge rail. The wind lost another piece of its circle and dragged harder from the right.
The fifth arm came next from the left.
It wobbled as it crossed, weighted end dipping toward the rail. Rusuf put his blade under the hinge as it returned, not lifting, only guiding. Blue waited with the bit pressed to the fifth tab.
"Five returning with the hinge riding low on the left," Ty said. "Careful, hinge is low near the rail edge."
Blue pushed while Rusuf guided the arm into its slot.
The fifth arm locked against the left housing.
The left side of the bridge went quiet.
The right side answered by pulling twice as hard.
JJ grabbed the case frame with both hands as the wind yanked from the right. The receiver lock held, but the rear guide rattled inside its tooth.
"The bridge is sulking on one side now," JJ said. "How many emotional phases does worker infrastructure get?"
"Three more if the numbers are honest across the bridge," Blue said. "That is not comfort, only arithmetic from here."
The second arm swept from the right and moved like a thrown beam.
Rusuf’s sword flashed up and caught the weighted end along the flat, redirecting it just enough that it cleared the rail rather than striking the receiver lip. The impact rang through the blade. His wrist dipped, then steadied.
"Two returning after the bounce against my blade," Rusuf said.
"Two returning on the right side now after the bounce," Ty repeated.
Blue shut the second tab with her shoulder braced.
The second arm locked, and the wind column lost its shape. Air punched out in separate bursts now, broken out of the circle. One burst hit Ty’s injured hand and drove cold through the bandage. He clenched his teeth and kept his palm high.
The fourth arm came next from the right.
JJ looked at Rusuf’s blade and shifted position.
"Your sword has done enough unpaid bridge work," she said. "Let mine take one sweep for once today."
Rusuf moved aside without arguing with her timing.
JJ stepped to the receiver edge and placed her sword flat under the fourth arm’s path. The arm swept, struck the flat with its padded end, and rode over the blade rather than dipping into the rail. JJ’s shoulders jolted from the force, but her stance held.
"Four returning, and my arms would like a formal complaint form," JJ said.
Blue shut the fourth tab before the arm bounced.
The fourth arm locked into the right housing.
Only the sixth arm remained on the bridge.
The sixth arm had been the heavy one. It hung on the right with its weighted end slightly raised, as if the missing wind from the other five vents had left all the pressure under that final hinge. The last vent howled through a narrow slot beneath it.
The case pulled backward against the receiver lock.
Ty felt the lock tooth strain under his hand.
"Six is holding the whole pull from the bridge," Ty said. "If it slams, the receiver may throw the rear guide loose."
Blue put the bit against the sixth tab and hesitated.
"Closing the tab may make it slam into place," she said. "Leaving it open keeps pulling the case backward."
Rusuf looked at the arm, then at the two swords.
"It needs a strike at the hinge before the tab closes," he said. "Break the over-speed before we ask it to home."
JJ lifted her sword while Rusuf lifted his beside her.
The service plate under Blue’s hand warmed one more time, revealing a narrow instruction line below the six marks.
The instruction read Six motions home, seventh sword strike.
