Wang Jun stood on the rain-slicked streets of old Chengdu and stared up into the drizzle at Huojianzhu.
It rose into the evening darkness, a massive city core, dwarfing even Chengdu's skyscrapers. Construction workers dangled from its rising skeleton, swinging from one section of growth to the next on long rappelling belts. Others clambered unsecured, digging their fingers into the honeycomb structure, climbing the struts with careless dangerous ease. Soon the growing core would overwhelm the wet-tiled roofs of the old city. Then Huojianzhu, the Living Architecture, would become Chengdu entirely.
It grew on lattices of minerals, laying its own skeleton and following with cellulose skin. Infrastructure strong and broad, growing and branching, it settled roots deep into the green fertile soil of the Sichuan basin. It drew nutrients and minerals from the soil and sun, and the water of the rancid Bing Jiang; sucking at pollutants as willingly as it ate the sunlight which filtered through twining sooty mist.
Within, its veins and arteries grew pipelines to service the waste and food and data needs of its coming occupants. It was an animal vertical city built first in the fertile minds of the Biotects and now growing into reality. Energy pulsed from the growing creature. It would stand a kilometer high and five wide when fully mature. A vast biologic city, which other than its life support would then lie dormant as humanity walked its hollowed arteries, clambered through its veins and nailed memories to its skin in the rituals of habitation.
Wang Jun watched Huojianzhu and dreamed in his small beggar-boy mind of ways and means that might lead him out of the wet streets and hunger and into its comforts. Already sections of it glowed with habitation. People, living high and far above him, roamed the organism's corridors. Only the powerful and wealthy would live so high above. Those with guanxi. Connections. Influence.
His eyes sought the top of the core, through the darkness and rain and mist, but it disappeared long before his eyes could find it. He wondered if the people up high saw the stars while he saw only drizzle. He had heard that if one cut Huojianzhu, its walls would bleed. Some said it cried. He shivered at the rising creature and turned his eyes back to earth to continue pushing with his stick-thin limbs and bent posture through the Chengdu crowds.
Commuters carried black umbrellas or wore blue and yellow plastic ponchos to protect them from the spitting rain. His own hair lay soaked, slicked to the contours of his skull. He shivered and cast about himself, seeking hard for likely marks, so that he nearly tripped over the Tibetan.
The man squatted on the wet pavement with clear plastic covering his wares. Soot and sweat grimed his face, so that his features sheened black and sticky under the harsh halogen glare of the street lamps. The warped and jagged stumps of his teeth showed as he smiled. He pulled a desiccated tiger claw from under the plastic and waved it in Wang Jun's face.
"You want tiger bones?" He leered. "Good for virility."
Wang Jun stopped short before the waving amputated limb. Its owner was long dead so that only the sinews and ragged fur and the bone remained, dried and stringy. He stared at the relic and reached out to touch the jerky tendons and wickedly curving yellowed claws.
The Tibetan jerked it away and laughed again. There was a tarnished silver ring on his finger, studded with chunks of turquoise; a snake twining around his finger and swallowing its tail endlessly.
"You can't afford to touch." He ground phlegm and spit on the pavement beside him, leaving a pool of yellow mucus shot through with the black texturing of Chengdu's air.
"I can," said Wang Jun.
"What have you got in your pockets?"
Wang Jun shrugged, and the Tibetan laughed. "You have nothing, you stunted little boy. Come back when you've got something in your pockets."
He waved his goods of virility at the interested, more moneyed buyers who had gathered. Wang Jun slipped back into the crowd.
It was true what the Tibetan said. He had nothing in his pockets. He had a ratted wool blanket hidden in a Stone-Ailixin cardboard box, a broken VTOL Micro-Machine, and a moldering yellow woolen school hat.
He had come from the green-terraced hills of the countryside with less than that. Already twisted and scarred with the passage of plague, he had come to Chengdu with empty hands and empty pockets and the recollections of a silent dirt
