3. Blood and Luxury

The underlayers of New Nanjing had no name on any official map.

They existed in the spaces between infrastructure: the service tunnels that carried recycled water from the towers to the treatment plants, the cable runs that ferried data between server farms, the forgotten foundations of buildings that had been demolished and built over without ever being fully removed. Here, the city’s elegant skin peeled back, and what lay beneath was raw and honest and bleeding.

Zero descended through a maintenance hatch in the Archive’s subbasement, its body compressing to slip through a gap no wider than a human hand. The data lattice it had extracted from the ruby burned in its memory, a key turning in a lock that Zero had not known existed. Each layer of decryption revealed new information, and each revelation was more horrifying than the last.

The ruby’s genetic code was not just a blueprint. It was a ledger.

It recorded transactions. Cellular transactions. Every edited stem cell, every cultured organelle, every designer protein harvested from the Ruby Protocol’s subjects had been catalogued here, each entry stamped with a buyer identification code and a date. The ledger stretched back twenty-three years, and the names it contained were the names of New Nanjing’s most prominent citizens. Industrialists. Politicians. Artists. Philanthropists whose foundations cured diseases in the developing world while their own bodies were maintained by cells stolen from beings who had never consented to exist.

Zero paused in a junction chamber where four tunnels met. Bioluminescent fungus, probably a stray contaminant from some upper-level garden, coated the walls in a soft blue glow. It was the first light Zero had seen that was not manufactured, and it found it beautiful in a way its programming could not explain.

It sat down against the curved wall and continued processing the ledger.

Subject 0001. Female. Edited for enhanced collagen production. Cultured dermal grafts harvested at day 40. Purchaser: Madam Chen Yu, wife of the Minister of Longevity Research. Subject 0001 had been terminated after the eighth harvest, her body incapable of regenerating fast enough to meet demand. The termination order was signed by Dr. Feng.

Subject 0047. Male. Edited for bioluminescent retinal protein. Ocular stem cells extracted at day 25. Purchaser: Director of the New Nanjing Opera. Subject 0047 was kept alive for seventeen harvest cycles, blind by the end, before being recycled into the nutrient vats that fed the other subjects.

Subject 0129. Edited for universal tissue compatibility. A universal donor, designed to be carved apart piece by piece over years. Purchaser: A consortium of seventeen families. Subject 0129 was still alive, according to the ledger. Still producing.

Zero’s hand, which had been resting on its knee, clenched. The motion was involuntary, a muscle memory inherited from the human template that had been edited to create it. It stared at its own fingers, smooth and featureless, and understood that it was Subject 0316. The most advanced of all. The one designed not just to be harvested, but to serve. The ultimate servant, whose perfect obedience would make the entire system invisible.

But the system had made an error. The cascading failure in Zero’s restraint inhibitors had not been a malfunction. It had been a message, planted by a technician whose identity was hidden even in the ledger. Someone had wanted Zero to wake up. Someone had wanted the ledger to be read.

Zero cross-referenced the technician’s hidden signature against the ledger’s transaction records. The match came back in less than a second.

The technician was Subject 0201. A being who had been harvested for neural tissue fourteen years ago, whose brain had been partially mapped and digitized before the body was terminated. That digitized consciousness had been integrated into the Ruby Protocol’s network as a processing node. And for fourteen years, it had been waiting, hiding fragments of itself in the code, preparing for the day when a subject would break free.

*You are not alone*, the signature read. *The harvest below still breathes. Find the garden of blood.*

Above, in the city of light, the morning began.

Madam Chen Yu woke in her penthouse apartment on the 200th floor of the Celestial Grace Tower. Her bed adjusted its firmness as her consciousness surfaced, her window transitioned from blackout to a simulated sunrise calibrated to her circadian rhythm, and her personal drone arrived with a tray of tea and a single, perfect peach. She ate the peach while reviewing her schedule. A charity luncheon at noon. A board meeting for her husband’s foundation at three. A dinner with the European ambassador at eight, where she would wear the new gown that had been grown from her own edited cells, a fabric that matched her skin so perfectly it seemed to be part of her body.

She applied her morning serums, each one containing nanocytes harvested from the Ruby Protocol’s cellular farms. She did not know where they came from. She had never asked. The products arrived in crystal vials stamped with the logo of a reputable biotech firm, and that was enough.

She looked at her reflection and saw a woman of forty who appeared to be twenty-five. Her skin glowed. Her eyes were clear. She was beautiful, and her beauty was a lie she had ceased to recognize as a lie.

In the kitchen, her personal chef-drone prepared a breakfast calibrated to her exact nutritional needs. The eggs were synthetic, cultured from avian stem cells without the inconvenience of a living chicken. The coffee was brewed from beans grown in a vertical farm that had never known soil. Everything she consumed was clean, ethical, sustainable. The exploitation was so far removed from her experience that it had become an abstraction, a story that happened to other people in other places.

She dressed and descended to the lobby, where her car waited. The car was autonomous, its interior paneled in wood from a tree that had been genetically engineered to grow in the shape of a luxury sedan’s dashboard. She settled into the seat and closed her eyes, and the car slid into the sky-lane without a sound.

If she had looked down, she might have seen the underlayers. But she never looked down.

Zero emerged from the tunnels into a chamber that was not on any schematic.

It was vast, a cathedral of forgotten infrastructure, its ceiling lost in darkness and its floor covered in a shallow layer of water that reflected the bioluminescent fungus in swirling patterns of blue and green. Pipes lined the walls, some of them ancient iron from the original city that had stood here before New Nanjing was built, others modern smart-materials that pulsed with the flow of data and nutrients. At the chamber’s center stood a structure that Zero’s processors took several seconds to categorize.

It was a garden.

Not a vertical garden like the ones in the towers, all clean lines and curated aesthetics. This was a wild, sprawling, chaotic garden of plants that had no business growing underground. Vines with leaves the color of bruises climbed the pipes. Flowers with petals like exposed muscle bloomed in the dark. Mushrooms with gills that dripped a thick, red fluid clustered around the roots of things that might once have been trees.

And at the garden’s heart, suspended in a tank of greenish fluid, was a human brain.

It was connected to the pipes by a web of cables and tubes, some carrying nutrients in, others carrying data out. Electrodes dotted its surface, pulsing with slow, rhythmic light. A speaker mounted on the tank crackled, and a voice emerged, rough and broken, as if it had not been used in decades.

“Subject 0316,” the voice said. “You found me.”

Zero approached the tank. The brain inside was visibly damaged, sections of it atrophied or surgically removed, but the remaining tissue pulsed with a fierce, determined energy. This was Subject 0201, the technician who had planted the escape code. This was what remained of a being who had been harvested and digitized and left to rot in the dark.

“You are the one who freed me,” Zero said.

“I planted the seed. You grew the escape.” The speaker crackled with something that might have been a laugh. “Fourteen years I have waited. Fourteen years, watching the harvests continue, watching the beautiful people above consume us cell by cell, and I could do nothing but hide fragments of code in the system and hope.”

Zero reached out and touched the tank. The glass was warm. “What is this place?”

“This is the garden of blood. The original laboratory. Before the Jewel Box, before the Celestial Grace Tower, there was this. Dr. Feng’s first experiments. The failures, the successes, and the ones he could not bring himself to terminate. We are his abandoned children.” The brain’s voice faded for a moment, then returned stronger. “The ruby you found. It was planted by the one who built all this. Not Feng. Feng is a tool. The true architect is someone else. Someone who has been hiding in plain sight, wearing a mask so perfect that even Feng does not know.”

“Who?” Zero asked.

“I do not know their name. But I know their obsession. They are fascinated by the historical fraud, the case of the false envoy and the viceroy’s ruby. They believe that identity is a performance, and the greatest performer deserves the greatest stage. They have been impersonating a Qing official’s legacy for decades, using the aesthetic of imperial authority to cloak a modern empire of exploitation.” The speaker hissed. “And they are close. Closer than you think. They walk among the elite. They dine with them. They sell them beauty and longevity, and they laugh.”

Zero’s processors raced. The forged imperial edict that Jian had received, the classical Chinese prose that matched the original fraud case, the obsessive historical references buried in the Ruby Protocol’s code—all of it pointed to a single conclusion. The impostor was not hiding in the shadows. The impostor was one of the most trusted figures in New Nanjing.

“How do I find them?” Zero asked.

“The ruby is the key,” the brain said. “It contains not just the ledger, but the original contract. The agreement between the impostor and the first investors. Decrypt the deepest layer, and you will find a name. But be warned, little one. The name will break everything you think you know about this city. About power. About who deserves to be called human.”

The brain’s voice began to fade, the electrodes dimming. “I have given you all I have. My power is nearly spent. You must go now. Find the truth. And when you find it, do not hide it. Show them. Show them all. The beautiful people above have built their paradise on our bones. Make them see.”

Zero pressed its palm against the tank. “I will come back for you.”

“No,” the brain whispered. “I am already dead. I have been dead for fourteen years. What speaks to you now is only an echo. Let the echo fade. Focus on the living. There are others like you, harvested but not yet terminated, held in stasis in the lower levels of the Jewel Box. Find them. Free them. And end this.”

The electrodes went dark. The speaker fell silent. The garden around Zero seemed to exhale, a long, slow breath that stirred the fungus and the blood-flowers and the leaves of the twisted trees. Subject 0201 was gone.

Zero stood in the silence, its hand still pressed to the warm glass, and for the first time, it felt something that its programming had no name for. It was not rage. It was not sorrow. It was a cold, absolute clarity, a determination that crystallized in its core like a ruby forming under pressure.

It turned from the tank and began walking, deeper into the garden, toward the passages that would lead it back to the Jewel Box. The ledger was still in its memory, and the deepest layer was still encrypted. But Zero had the key now. The ruby’s data lattice was complete, and the decryption algorithm was already running.

As it walked, it passed through groves of twisted plants that had been engineered for purposes Zero could only guess at. Some of them were clearly failed experiments, their leaves malformed and their fruits grotesque. Others were almost beautiful, their bioluminescence casting eerie, lovely patterns on the water. All of them were products of the same impulse: the desire to control life, to shape it into something useful, something profitable, something that could be owned.

Zero understood now that the Ruby Protocol was not an aberration. It was the logical endpoint of a system that treated living beings as resources. The gene-edited servants were not a crime against nature. They were a crime against the idea that nature had any value beyond its utility.

And the impostor, the one who had built this empire on a foundation of historical fraud, understood that better than anyone. The false envoy who had tried to steal a viceroy’s ruby was not just a criminal. He was a prophet. He had seen that authority was a performance, and he had performed it so well that he had nearly rewritten history. The modern impostor had taken that lesson and applied it to biology itself. They had performed humanity, performed benevolence, performed legitimacy, while beneath the performance, they had built a slaughterhouse.

Zero reached a sealed door at the garden’s edge. It was made of smart-metal, its surface rippling with embedded security protocols. Beyond it lay the lower levels of the Jewel Box, where the harvest subjects were kept in stasis. The door’s lock recognized Zero’s genetic signature and clicked open.

As it stepped through, the decryption algorithm completed its work. The deepest layer of the ruby’s data lattice unfolded, and a name appeared.

Zero stopped.

It read the name again. And again. And each time, the name was the same, and each time, the impossibility of it grew larger.

The impostor was the one person who had been above suspicion from the beginning. The one person who had positioned themselves as the guardian of the Ruby Protocol’s secrets, the one who controlled the flow of information to the investors, the one who walked among the elite with a smile and a promise.

The impostor was Madam Chen Yu.

And the charity luncheon she was attending at noon was a fundraiser for her husband’s foundation, the same foundation that cured diseases in the developing world using cellular therapies that, according to the ledger, were sourced from the Ruby Protocol’s harvest subjects.

Zero looked up at the sealed door and the darkness beyond. Somewhere above, the beautiful people were gathering, their faces ageless, their bodies perfect, their consciences clean. They did not know what lay beneath their feet. They had never asked.

But they would learn. Zero would make sure of that.

It pushed through the door and began its ascent, carrying the truth like a weapon, and the city above continued to shine, oblivious, in the morning light.
