Chapter 1: The Sunken Fortress
The damp stone walls of the old guard chamber smelled of wet slate, river silt, and the faint, sweet trace of burnt willow ash. Two levels above, the muffled thud-thud-thud of courtesans’ silk-shod feet vibrated through the floorboards—a rhythmic, distant heartbeat of the Verdigris House that none of the children below belonged to.
Seven-year-old Maomao didn't look up from her workbench. Her hands, already scarred with tiny chemical burns and stained an unsightly shade of green from crushing wild herbs, meticulously bound a length of cleaned pig intestine around a hollow bird quill. Her fingers were small, her stature stunted from a combination of early malnutrition and the deliberate testing of mild toxins on her own flesh, but her movements were entirely precise.
"Is the milk diluted enough?" a quiet voice asked from the shadows.
It was Chao. At eleven years old, he was one of the oldest in the tunnels, his skin perpetually grayed by the alluvial clay he dug from the riverbank during low tide.
"Three parts boiled river water to one part goat’s milk," Maomao replied, her voice flat and clinically detached. "The proteins in raw milk are too dense for a human infant’s stomach. If you don't break them down, her gut will twist, and she will bleed out from the inside. Did you dissolve the maltose syrup?"
"Yes. A small pinch, just like you noted on the slab." Chao pointed to the flat basalt stone in the center of the room, where characters scratched in white river limestone detailed the exact measurements for infant survival.
Maomao nodded once. She slipped a piece of fine, porous linen—swiped from Meimei’s discarded handkerchiefs—over the sharp tip of the quill, binding it tightly with a strand of silk thread. She poured the warm, sweet mixture into the open end of the sausage casing, tied it shut, and gently squeezed. A perfect, slow drop of milk saturated the linen nipple.
Turning to the warmest corner of the basalt chamber, Maomao approached a wicker laundry basket. It was suspended from an iron ceiling ring by sturdy ropes, keeping it safe from the damp floor and the blind cave crickets that crawled through the ruins. Inside lay a ten-day-old infant.
Maomao had found her in the frozen back alley behind the brothel, abandoned by a lower-ranking courtesan who had successfully hidden or had a cryptic pregnancy under heavy bindings until labor tore through her. Maomao had told herself she hadn't rescued the child out of grand heroism. She told herself she had simply looked at the blue-tinted, barely breathing newborn and felt a cold, analytical refusal to let a fresh medical specimen go to waste.
But as she gently nudged the artificial nipple into the baby's mouth, a silent, buried truth remained locked away in the deepest, darkest corner of her mind. She would never utter it. She would never admit it to Chao, to Luomen, or even to herself. But she had scooped that freezing bundle out of the mud because she knew exactly what it felt like to be unwanted. She knew the weight of being a discarded thing, a mistake to be hidden away. In a world that treated children like inconveniences or currency, she simply could not look away from a mirror of her own abandonment. She hated waste, but deep, deep down, she hated the cruelty of a discarded life even more.
As the baby’s mouth found the wet linen and began to suckle hungrily, Maomao felt her own frantic pulse finally settle.
Her heart had been hammering since noon. She had been cornered in a narrow corridor by a bloated, wealthy client whose fingers reeked of cheap wine and banquet grease. He had grabbed her small wrist, his grip bruising her frail skin, and dragged her toward a curtained alcove. She had fought like a feral cat, biting and clawing, but his weight was absolute.
Then, the Madam had intervened. Grams’ heavy hand had yanked the man back, her sharp voice summoning the bouncers to throw him into the street. For a fleeting second, Maomao had felt a surge of childish relief—until she heard Grams mutter to a nearby maid: “Ban that idiot permanently. If he ruins or takes the girl now, she won't be worth a copper coin when she’s old enough to debut. I won't have a prime investment broken before she can earn back a single grain of rice.”
The words had frozen the blood in Maomao’s veins. Grams hadn't saved her out of kindness. She had saved her out of inventory management. To the Madam, Maomao was a financial asset currently depreciating due to premature handling.
Adults could not be trusted. They were either predators driven by lust, or flesh peddlers driven by transaction.
Except for Luomen. Maomao gladly accepted her blood relationship to the gentle, neutered doctor who ran the small clinic. When Joka had first explained the anatomy of a eunuch to her, Maomao hadn’t felt pity; she had felt a profound sense of relief. A man without the biological mechanics for desire was the only safe man in the Empire. He was a castrated animal, and castrated animals did not hunt children.
But even Luomen could not be fully trusted with her secrets. The adult world was self-absorbed, so Maomao weaponized their routines. When dusk fell, she would tell Luomen she was sleeping at the Verdigris House. When she vanished from the brothel after her writing lessons, the sisters assumed she had run back to the clinic. Instead, Maomao used the "Squeeze"—the tight, vertical chimney behind the communal bathhouse where an ancient support pillar had rotted away—to drop down into the forgotten, subterranean military fortress of Houchengzui. That isn’t to say she never stayed the night at either place; to avoid doing so would jeopardize the other outcasts.
"The tide is turning," a voice called out.
Two more children emerged from the lower water-gate sluice, dripping with brackish river water. It was Kuan, a lanky ten-year-old with a natural knack for carpentry, and Mei-Ling, a nine-year-old girl carrying a bundle of wild river reeds.
"We pulled three carp from the basket traps," Kuan reported, wiping his brow. "And the willow driftwood we gathered from the banks is drying near the ventilation flue. The smoke won't build up; it's drawing straight into the old city sewer line blocks away, just like you said it would."
"Good," Maomao said, her eyes remaining on the feeding infant. "Did you harvest the weeds?"
Mei-Ling proudly produced a handful of green leaves and thick, muddy roots. "Wood sorrel from the shaded bank, and three large kudzu roots. We smashed the roots in the river water to pull the white starch out."
"Boil the wood sorrel into the congee tonight," Maomao commanded, her tone that of a strict physician. "It is sour because it contains the element that keeps your gums from bleeding and your skin from bruising. The kudzu starch will thicken the rice soup. A single cup of grain will feed all of us if the congee is thick enough."
These children were runaways, bastards, and street rats who had discovered the bottom-up entrance to the ruins where the city drainage met the major trade river. They had originally been terrified of the strange, unblinking seven-year-old girl who occupied the old guard chamber. But Maomao had offered them a transaction they could understand: I provide a warm shelter where the predators cannot fit, and medicine to cure your river-fevers. You provide the physical labor of hauling wood, weaving bamboo fish traps, and guarding the baby.
It was a bloodless contract on the surface, a practical arrangement born of survival. But underneath her rigid ledgers and sharp commands, Maomao held a profound, fiercely guarded affection for this patchwork family. They were the only people in the world who didn't look at her as a future commodity or a tragic mistake. They were her responsibility, her community, and the only place where she felt a quiet semblance of peace. She would never say the words, but she would keep them alive with every ounce of her medical wit.
"Maomao," Chao spoke up, his voice trembling slightly as he pulled a heavy, wide-bellied clay jar from beneath a loose stone in the floor. He tipped it over, pouring a small mountain of copper coins onto the dirt. "We counted it three times. With the pottery sales from this morning and the fish trap coppers from yesterday... we have enough."
The children gathered around, their breathing shallow in the dim light of the charcoal hearth.
"Enough for the registry fee," Kuan whispered, his eyes wide.
Maomao pulled a flattened piece of bamboo from her vest—her ledger—and verified the numbers with a sharp scratch of charcoal. "The low-tier master tile-potter outside the slums agreed to take an apprentice, but he demanded twenty silver pieces to sign the guild contract and issue official identity papers. We have enough copper to equal twenty-two."
She looked up, her gaze landing squarely on Chao. "Tomorrow, you walk into his shop with your hands covered in river clay. You hand him the coppers. You do not leave until he signs the parchment and hands you the wooden tally."
Chao’s eyes brimmed with tears, his chest heaving as he looked at the coins. In this empire, a street rat was a non-person. They could be killed, enslaved, or violated with zero legal consequence. But a guild apprentice had a name. A guild apprentice had papers. Chao was buying his way into legal society.
Mei-Ling and Kuan began to weep silently, hugging Chao’s shoulders. Maomao merely watched them, her face an unreadable mask of clinical satisfaction. Her grand strategy was working. They would buy the children out of the dark, one by one. Kuan would be next, apprenticed to a builder. Then Mei-Ling to a weaver. And eventually, Maomao would accumulate enough coins to buy a formal, registered apprenticeship under Luomen, permanently erasing her value from the Madam's ledger. Hopefully. Maybe. It worries her why a physician would work in the slums, but he has a jade tally, not wooden, so a registered physician he is.
The baby finished the milk, letting out a soft, contented sigh in her suspended wicker nest.
"We will call her Ren," Mei-Ling whispered, wiping her nose. "Like the lotus. Because she started in the river mud, but she’s going to bloom."
"Name her what you like," Maomao said, turning back to her workbench to clean the intestine bladder. "Just ensure her bedding stays dry. Dampness breeds pneumonia."
They were a well-oiled machine. They had a home, a diet of fish and nutrient-dense congee, an education, and a ledger that was successfully buying their freedom.
Maomao stood up, adjusting her medicine bundle. It was time to slip back through the Squeeze, walk out of the Verdigris House, and return to Luomen’s clinic for her afternoon lessons and actually stay the night. She stepped out into the crowded, bustling streets of the Pleasure District, her mind already calculating the proper dosage of a new root she wanted to dry.
"You."
The voice was sudden, heavy, and booming with an erratic, intense energy.
Maomao froze. Standing near the edge of the market crowd was a high-ranking military strategist. His uniform was opulent—dark, high-collared imperial robes adorned with heavy silk embroidery, polished jade ornaments, and tassels that denoted absolute authority.
But it wasn't his uniform that made her stomach drop. It was his eyes.
Through his unique, twisted perception of the world, the man was staring directly at her face. His eyes were wide, hungry, and completely fixated. He didn't see a stray child in the dirt; he saw something hyper-specific. He took a predatory step forward, his voice trembling with an obsessive weight.
"You look... just like your mother."
The realization hit seven-year-old Maomao like a splash of freezing river water. Her mother was Fengxian, the fallen, ruined courtesan. And this powerful, high-ranking official was staring at a seven-year-old child because she was a younger, miniature model of the woman he used to frequent.
A predator. A sick, twisted monster who wanted the child version because the original was gone. If the Emperor could do it, why wouldn't a military official with a sword and imperial backing think he had the right?
Runaway. Runaway. Runaway.
The chant repeated like a frantic drumbeat in her skull. Her feet moved before her conscious mind could even process the terror. She didn't care about his uniform or his authority. She dived blindly into the crowd, dodging between the silk skirts of courtesans and the legs of drunken merchants, sprinting with a feral, desperate speed toward the only place where giant, predatory adults could never follow.
She ran for the dark. She ran for the Squeeze.
