The jar of alcohol started it.
Half a watch before nightfall, the gray-white knot of flesh—cut from a war-hound's skull, six days steeping in spirits—went mad against the glass. It thumped the jar's base against the parapet in a steady tick, the wax seal already crazed. Zhou Zhengting pressed it down with both hands and called over: "What's it answering?"
"Something outside," Chen Jin said.
The dark past the wall held no movement yet. The corner of his vision blinked first:
[ALERT: Large swarm inbound]
[Primary threat assessment: general-class]
A smaller line underneath: kindred signal detected. The thing in the jar was answering whatever gave orders out there.
"Pass it down," Chen Jin said. "Full garrison to the north wall parapets. Reloaded rounds staged within arm's reach. And get Xiao Mao up here—all his mechanics with him."
The order went down layer by layer. Reloaded rounds moved up in sacks, issued by hand, sack mouths tied tight and shoved into empty chest pouches. The cooks hauled cauldrons, door planks, and rolling logs down to both flanks. Xiao Mao came up the ladder with his tool roll and a dozen mechanics behind him, an adjustable wrench at every belt. Zhou Zhengting worked along the wall with the master register, calling the roll section by section, and at each name the man answered, "Here." The answers didn't carry far at night. One gust and they were gone.
The swarm came without a sound.
That was the wrongest part of it. The swarms of the past nights had come howling—into the wire, against the parapet, piling themselves onto rifle muzzles. Tonight the dark held only the rasp of claws on ground, layer under layer, filling the trench. The ones in front died on the stakes; the ones behind climbed the bodies and packed them down, the way dockhands stack cargo. In half a watch the trench was half full.
"It's paving with its own," Lei Changgeng said, voice pressed flat. "Fill the road flat, and the big ones get their turn."
The west battery erupted first. Fierce pushes, claws hooking the parapet lip—but nothing came over. The west section called out half a squad of reserves, and then the gong at the east gate tower started up, cracking with hurry.
"Hold." Chen Jin kept his eyes on the midsection. "The west is bait. It counted our rifles."
The midsection was the patch over the old collapse. New brick, shallow mortar, a different color under the torchlight from the wall on either side. The main crest of the swarm drove at exactly that—no howl, no raggedness, one wave riding the next, gnawing at the new seams.
By the time Chen Jin got there, the east culvert's iron grating was crying out again—torn at from inside, one long note after another, the bars humming with it. Seven garrison veterans held the culvert mouth, rifle stocks jammed crossways through the bars as props, backs flat to the channel wall, drip and bug-spit coming down on their heads. The grating wouldn't last half a watch. He listened for two breaths and peeled off four men. "Wedge the grate and hold. Don't chase. Xiao Mao's people right behind."
Xiao Mao's shout came from behind: "The midsection? Who's got the midsection?"
"Me."
The midsection held. The culvert held. But the half squad pinned by the feint couldn't come loose to help, and along the east seam of the midsection, a man-length of the wall let go—not a breach, a slope of fallen brick—and two garrison men lay out on it and did not get up.
When Chen Jin came up, a fire-poker lay across the gap, a ladle still hooked on its end.
"Zhao Tieshuan." The veteran tucked the ladle into his belt and gave a fist salute. "Garrison cook. Thirty years at the pot. This stretch of wall is mine to plug—this old frame can still stop up one hole."
And he did plug it. Twenty-odd cooks and quartermasters, nothing on them worth calling armor, sealing the gap with door planks, rolling logs, and cooking cauldrons, layer on layer. Hound-classes came down the slope, hooked claws in the new brick and tore—one died with its claws still seated in the mortar, never pulled free.
Then a war-hound class shouldered up the slope. A head taller than a man, old plating studded with broken shafts from the nights before, climbing the paved dead step by step, one paw swatting two cauldrons clean off the pile. Chen Jin dropped down to meet it head-on and put a blade into the neck seam. The thing's dying toss carried him into the rubble, and the old shoulder wound tore open on the spot. He pulled the blade out from beside the carcass with hot reek all over half his face, and the corner of his vision blinked:
[Kill confirmed: War-hound class x1. +50 Embers.]
Chen Jin counted this one into the books. The corner of his vision was blinking in sheets now:
[Kill confirmed: Hound-class x1. +10 Embers.]
[Kill confirmed: Hound-class x1. +10 Embers.]
[Humans saved +1]
Past counting. He'd square it all when the night was over.
The wounded came off the wall and went west, and the two lamps at the casualty shed still burned—one over the diagnosis board, one over the path at the door, stretcher shadows swinging across the canvas with every trip. Wen Heng sorted the wounded under the light. The red cloth strips were gone; she tied the last one to a man who could still walk and sent him off moving, hand pressed to his own wound. The carried-down passed her one at a time, two at a time; the notebook lay open on her knee, one line written, one dip of ink, the inkwell skinning over, no time to scrape it.
At the seventh line the pen stopped. The lamp wick spat; she trimmed it short with the scissors and went on writing.
Coming down for a fresh bandage, Chen Jin said, "Last night I thought I could get through this with nobody dead."
He regretted it before the words were cold. The fight wasn't finished; a line like that was a wish made at the front. Wen Heng didn't look up. "I'm counting. Go hold your shoulder down. You're bleeding through."
There was a second lot that came with ugly words, and they came before third watch. A committeeman of the Provisional Control Committee came up the north wall, silk vest glaring white among the soldiery. He lost a step of mud coming up the ladder—men from the Port Office side shouldn't have the west wall's clay on their shoes; where he'd been first, in the middle of the night, nobody asked.
He gave Chen Jin a bow first. The fingers on the bow were steady. The hands he folded back into his sleeves afterward were not. He said Chairman Bi sent his regards to the men on the wall, and then came to business: open the east district, pull everyone into the west. "Let three thousand out, and the tide recedes. Until the fleet makes port, the city should be allowed to keep a keepsake."
"Keepsake." Zhou Zhengting set his enamel mug down hard on the parapet. "Harbor Defense Code, first article: hold the ground, lose nothing. Which article are you reading?"
"Deputy Commander Zhou. Be reasonable—"
Chen Jin skipped the code. He walked over and lifted the jar of alcohol to eye level for the silk vest. Inside, the knot of flesh still knocked against the glass, one thump at a time, the liquor gone cloudy.
"Look at it. That thing out there and this thing in the jar are the same machinery. Your keepsake—three thousand souls out the gate—it's not feeding the tide. It's feeding that. Every retreat it's ever bought with people, it learned from. This swarm doesn't take surrender."
The silk vest looked at the flesh, worked his throat, and said nothing. He went down the ladder with a hand on the rail, faster than he'd come up.
In the coldest hour before dawn, the swarm pulled back.
Neatly. Front rank to rear, wounded carried off, dead carried off, the paving in the trench hauled out too—what couldn't be hauled got walked over. Things that had held the wall in their teeth half a watch ago let go all at once, as if a whistle only they could hear had sounded.
The whistle was real. Three short, one long, rolling in from the dark past the wall, running flat along the ground; and in the jar, the flesh knocked once with each beat.
In the trench, what paving-bugs hadn't been hauled away turned to either side, opening a lane.
Torches reached out. Two hundred paces off, something stood up out of the dark.
Not crouched. Standing. Gray-white plating in layers, ring locked inside ring; the two jaws crossed and clipped once, and the men on the parapet heard brick grit trickle down. It stood there without moving, like something waiting on the accounts.
[Threat confirmed: general-class. Designation: Grey Jaws.]
The parapet went quiet. Nobody breathing loud. One man gathered his round-sack tighter into his chest. Xiao Mao's wrench rang off a brick edge—one clang—and he flinched first of anyone, closed his fist around the handle.
At first gray light, the system pushed the night's ledger up in front of him:
[Night tally: Hound-class x79, War-hound class x1, Humans saved x1]
[Embers: 1480]
Chen Jin opened the STORE. Thermal lance, 150. Tier-2 Genetic Booster, 400. Standard Power Armor, 800. One thousand three hundred fifty, all three together.
It covered. It left one hundred thirty.
"Leave it on the books," he said. "Principal and interest. All of it comes due this morning."
