The fire stayed inside the wall for three breaths, which made it worse.
Open flame would have been honest. The seams behind the receiver glowed in clean rows, each one thin enough to pretend control still existed. Heat rolled out anyway and crawled across the bridge rail, the tray, the glass case, and Ty’s torn bandage.
Blue kept the dead fuse pinned in Daemon’s cut.
"The fire line is taking the wrong path, but it is feeding on pressure," she said.
JJ held the case frame and watched the frost vanish from the glass.
"I need that sentence to end somewhere survivable," she said.
"Then we keep the fire moving away from the board and bodies."
The wall thumped again behind the receiver plates.
The next row of seams opened above the first. Orange light ran through them in a straight band, then bent toward the tray. The board warmed under the service pin. The two sickles opened wider, their hooked tips following the heat lines as if they expected the correction path to turn back.
Rusuf kept the maintenance sword under the stone lip.
"The lip is lighter, but the sword is heating," he said.
Yun-Jin shifted the cloth under the hook contact.
"The hook wants the wrist again, and heat is making it pull harder," she said.
Ty looked at the copper line. It had darkened near the tray edge, and the loose hook trembled above the buried body’s wrist ring. If the hook touched, the fire line would get a body path. The sickles had cut the wrong kill loose once. Ty had no reason to assume they could cut it clean twice.
"Keep the hook open and away from the wrist ring," Ty said.
Yun-Jin gave him a flat look over the cloth.
"I understood that before the room started cooking my hand."
JJ glanced down at Yun-Jin’s braced hands.
"Switch with me if your fingers start failing."
"You are holding the case while it argues."
"The case and I are in a committed disagreement, but I can multitask."
The case body pressed one finger to the glass again.
JJ shoved the frame back into the lock with her shoulder.
"Nobody asked for your opinion, reused face in glass."
Blue looked over the board without lifting the cloth.
"The fire line is trying to complete a loop," she said. "It goes from the board into the wall, then comes back through the copper line toward the wrist ring."
Ty followed the path with his eyes. The wall seams opened in rows, and each row angled a little closer to the receiver. The blaze held shape like a routed argument. The channel carried heat like a message and kept asking the bodies to sign for it.
"The sickles need to cut the return before it reaches the hook," Ty said.
"They need to hear it first, or they cut blind," Blue said.
JJ’s laugh came out dry and rough enough to hurt.
"That is becoming my least favorite rule in this room."
The board ground under the fuse again, and both sickles turned toward the copper line.
Yun-Jin held the hook back with the cloth, but the heat had started reaching through. Her knuckles tightened, and her wrist shook once. She moved her other hand under the first and braced herself against the tray.
Rusuf saw it before Yun-Jin’s grip slipped.
"Use the maintenance sword as the return bait," he said.
Blue looked at him without lifting the fuse.
"The sword is already under the lip and taking weight."
"It is touching the stone lip, not the wrist ring. If I angle the grip toward the board, the return path may prefer the hot metal over Yun-Jin’s hand."
"It may also heat the lip and seal the body under stone harder."
Rusuf shifted his stance around the sword grip.
"The body stays buried either way. Yun-Jin’s hand should stay attached."
Yun-Jin’s mouth tightened around the answer before she spoke.
"I hate practical kindness during active disasters like this."
"I have been told mine lacks charm under pressure."
Ty looked at the sword, the lip, and the board. The maintenance blade already bridged stone and tray. The fire wanted a return path. If Rusuf gave it metal, the sickles could hear the return without letting the hook touch the wrist ring.
"Angle the grip to the board, but keep the flat under the lip," Ty said. "Blue, lift the fuse enough to make the sickles listen. Yun-Jin, move the hook away when the return jumps."
"That plan has three ways to punish one mistake," JJ said.
"Then we make no mistake where the room can use it."
"That sentence has never met this hallway properly."
Rusuf turned the sword by a few degrees. The flat stayed under the lip, the grip angled toward the board, and heat moved at once.
It ran down the sword in a thin line, fast enough that Rusuf’s fingers jerked around the grip. He kept hold. The stone lip lifted a fraction as the metal expanded under it.
The buried body’s open hand twitched under the stone.
Yun-Jin pulled the hook back from the wrist ring by the width of a nail.
Blue loosened the cloth over the dead fuse.
The board bit down, and both sickles snapped toward the sword grip.
They held there, vibrating over the return path, while the fire line knocked through the wall behind them. One seam opened. Then another. The heat rushed into the sword, hit Daemon’s dead fuse, and tried to run back toward the copper line.
"Now, while both sickles hear the return path clearly," Blue said.
The sickles cut the return path through the heat.
The left sickle shaved the heat line before it reached the board’s case side. The right sickle crossed the stone side and nicked the edge of Daemon’s fuse. The cracked ceramic spat one white spark and stayed wedged in the cut.
The hook contact dropped away from the wrist ring.
Yun-Jin pulled her hand back and flexed her fingers.
"Still mine and still moving after the hook slipped," she said.
"That sounded personal enough to keep after this."
Rusuf breathed out through his teeth and shifted the sword back to flat. His palm had reddened around the grip, but the blade still held the lip.
"Fire line moved off the hook and into the wall," he said.
Blue watched the wall through the orange seams.
"It moved into the outer channel beyond the receiver."
The rows of seams behind the receiver opened wider.
Heat burst through them in staggered strips. Each strip crossed the wall and vanished into a second set of channels near the bridge floor. The room filled with hard orange light, chopped into bars by the seams. The glass case reflected it in broken pieces. The body inside stayed still, finger still on the glass with the pressure gone.
The buried body’s hand relaxed under the stone.
Ty felt the first honest change in the room.
The bodies stopped asking, and the fire started answering.
"Outer channel is taking the argument away from both bodies," Blue said.
"Where does it carry the argument after this?" Ty asked.
The answer came from the bridge floor beneath them.
Small vents opened along both rails, one after another, each vent no wider than two fingers. Hot air rushed downward. It struck the lower trough beneath the case track and moved through the bridge supports.
The old frost under the bridge broke apart.
White flakes lifted from the support seams, and JJ stared at the floor.
"Please tell me those flakes belong to normal track work."
Blue crouched lower without touching the rising flakes.
"Old stabilizer deposits from the freight supports below us," she said. "Bone ash, lime, and whatever this route used to stiffen freight tracks."
"That answer made the problem worse in several directions."
The fire storm moved through the vents beneath the rails.
It punched in measured bursts, each one pushing white flakes from the supports. The flakes spun under the bridge, rising with the heat and then dropping back toward the rails. More vents opened ahead of the case track.
Ty looked at the board while the sickles stayed open.
The dead fuse stayed caught in Daemon’s cut.
The fire line had left the bodies and entered the bridge bones.
"Next system is under the track and already waking," he said.
Blue wiped sweat from her cheek with her sleeve and looked at the lifting flakes.
"Bone stabilizers are waking under heat below the case track," she said.
Rusuf glanced at the white storm building beneath the bridge.
"If those deposits lift into the case track, the receiver may lose the guide."
JJ adjusted her grip on the frame as flakes rose.
"So we survived the fire argument and inherited a floor made of angry powder."
The vents punched again beneath the bridge supports.
This time the white flakes rose high enough to strike the underside of the glass case.
Ty stepped back from the tray as the bridge floor answered with a dry rattle.
The fire storm ran under the rails, and the bone storm began to climb.
