Chapter 8 · Point of No Return

The risk disclosure was written on two sheets of A4 paper, handwritten, the script as neat as a judicial document.

Farhan had not used a screen to display it—screens left traces. Physical paper was easier to destroy. He spread the two sheets flat in front of Lu Yuan, the paper’s edges held down by a cup of water and a key. The key was for his cage workstation. The water was at the right temperature for the five-year-old child in his arms to take her medicine.

“Take a look. No rush,” Farhan said.

Lu Yuan set his daughter down on a folding chair beside him, unscrewed the cap of her water bottle, confirmed the temperature was right, then broke the pill in half and handed it to her. The little girl took the pill obediently, drank the water, tilted her head back and swallowed—the whole process as quiet as a well-trained animal. She was used to taking medicine. Used to not complaining about the bitterness.

When that was done, Lu Yuan sat on the other side of the folding table and picked up the two sheets.

Lu Yuan’s gaze stopped at the line “Freezing of medical authorization”—longer than it had lingered on any other line.

Farhan did not rush him. He poured a glass of water for himself, leaned against the wall, and drank slowly. The base was three stories underground with no windows; the ventilation system delivered filtered air carrying a faint metallic smell. Somewhere in the distance, a mechanical keyboard clattered at a rapid pace, the rhythm like heavy rain on a tin roof.

Lu Yuan placed the two sheets back on the table. He did not read them a second time.

“Got a pen?”

Farhan fished a ballpoint pen from his pocket—also ordinary, unconnected, plastic-cased, with a ring of bite marks on the cap. He placed it on the paper and slid it across the table.

Lu Yuan picked up the pen, flipped to the bottom of the second page, and paused above the signature line.

“My daughter—if I sign this—will she—”

“She’s already within the risk range,” Farhan said, his voice without emotion but not cruel. “The moment you opened that plastic storage bin, she was already within the risk range. Signing doesn’t increase her risk. But—” He paused. “What you do after signing might expand her risk.”

“Might also eliminate her risk.”

“Might.”

Lu Yuan looked down at the line beneath the tip of his pen. A signature took only two seconds. The side channel hidden among a hundred and twenty thousand satellites—its activation code was already in his memory. Farhan had spent the previous hours teaching him the complete signaling structure of the SkyWalker protocol, and he had memorized it all. No notes. No recordings. No digital trace.

Two sheets of A4 paper. One folding table. One ballpoint pen. One Faraday cage compartment three stories underground.

This was everything a world-changing signing ceremony deserved.

“I’m not here to overthrow Starlink,” Lu Yuan said. His voice was not as hoarse as he had imagined; instead it was strangely calm, like someone stating a truth he had confirmed long ago. “I’m here to keep my daughter alive.”

He did not look up at Farhan. He did not read the dangerous numbers on those two sheets again.

“But if overthrowing Starlink is the condition for keeping her alive—” Lu Yuan wrote the first stroke of his name—the left radical of “Lu” tilting slightly to the right under his uneven pressure—“then let’s overthrow it.”

He finished the last stroke and placed the pen back on the table. The ink on the paper glistened faintly under the fluorescent light. The signature was clean, clear, no scrawl, no hesitant scratches.

Farhan walked over, picked up the two sheets, did not look at the signature, and fed them directly into a shredder. The sound of cutting blades rang through the quiet compartment for about two seconds. The confetti fell into a transparent recycling bag, fine as a miniature snow.

“The protocol exists only in your mind now,” Farhan said. “Come on. I’ll show you SkyWalker’s real test environment. Amina’s new firmware sample from Lagos arrived earlier than expected.”

He turned and walked out of the workstation, pausing at the door.

“Your daughter—we’ll find a way. Not because there are guarantees. Because we’re all in this boat now.”

Lu Yuan stood up, lifting his daughter, who had already drifted off to sleep on the folding chair. Her weight was so light it made him feel, every time he carried her, the weight of those numbers—the numbers he had only truly understood the meaning of after he had signed.

Berlin. Outside the window of the European Union Digital Freedom Committee office, the sky was that northern German lead-gray, low clouds pressing over the city like a heavy quilt.

Isabel Krause stood at the window. Her coffee had gone cold. She wore a sharply tailored gray blazer—she had a committee hearing on Starlink service pricing transparency to attend this morning. But her attention was neither on the view nor on the coffee, but on the freshly decrypted encrypted email on her screen.

The email had come through an anonymous relay node inside the Data Party, passed through four layers of encryption, the text so short it was only two lines.

「RF-01 has been naturalized. Former Huawei RF. Core member of the 2048 6G prototype team.」

Isabel stared at the word “Huawei” for several seconds. Then she set down her coffee cup and sat back at her desk. Her ten fingers hovered above the keyboard without immediately pressing down.

She was the EU Digital Freedom Committee’s appointed Special Envoy for Starlink Affairs—an official role representing the EU in service agreement negotiations with Starlink and overseeing its regulatory compliance in the European market. But what had kept her in this position for four years was the razor-thin relationship she maintained simultaneously between the Data Party and Starlink’s upper management. She passed Starlink’s movements to the Data Party—not everything, selected pieces. She passed the Data Party’s activities to Starlink—again, not everything, selected pieces.

She thought she was controlling both lines quite well.

She pulled up the internal archive system and typed “Lu Yuan.” Search results returned a brief résumé summary—not long, but every line tightened her brow.

Lu Yuan · Male · Joined Institute 201 RF Laboratory, Huawei, 2048

Related persons:

Isabel closed her eyes, leaned back in her chair, letting the information settle slowly.

A former Huawei RF core engineer. Daughter sick. Copper-tier quota insufficient. Turned to signal cloning—then discovered, pursued—then connected to the Data Party by Farhan.

This did not look like a recruited spy. It looked like a person pushed to the edge by the system.

But that made her more uneasy.

A person pushed to the edge by the system was harder to predict than someone driven by ideology. Idealists had bottom lines, calculable decision logic. But a person protecting their child—their bottom line was mobile, their decision logic was dynamic, the price they were willing to pay had no upper limit.

She dialed a number.

Encrypted line. The waiting tone before connection was a specially processed chaotic white noise with no frequency characteristics—even if covered by Starlink’s physical layer interference array, no information could be extracted from it.

“Milan.”

“Isabel.” Milan’s voice came through the line. The background was silent as an empty room, only his steady breathing and occasional keyboard clicks. “It’s been a while since you last contacted me directly.”

“The Data Party has a new member,” Isabel said without preamble. She did not have the habit of easing into conversations.

“I know.”

Isabel’s finger tapped once against the edge of her desk—an almost imperceptible motion. Milan’s tone when he said “I know” was too flat, like someone who had already anticipated this news, not someone hearing fresh intelligence.

“You know?”

“Former Huawei RF engineer. Lu Yuan. Daughter is sick. Copper-tier quota insufficient—so he did something most people wouldn’t do.”

Isabel was silent for several seconds. Milan’s details were more extensive than she had imagined. Not just “someone new joined”—he knew the person’s background, motivation, even family situation. This meant Milan had more than one intelligence source inside the Data Party.

“You knew before I did,” she said. It was not a question.

“Isabel, I see what the Data Party is doing every single day. Not because I have spies—but because they use the system I designed, eating the bait I left. Every one of their data packets leaves traces in my protocol layer. I know when they come online, when they go offline, when they compile new firmware on a server in Singapore, when they connect a new terminal at a base in Lagos.”

His voice carried no pride. Just a statement of fact. But it was that very calm that sent a chill through Isabel.

“Then what do you need me for?”

Milan paused on the other end. When his voice returned, there was a subtle shift in tone—softer, like someone about to say something important but not wanting it to sound important.

“Isabel, I have a mousetrap here that everyone thinks is cheese.”

Isabel did not respond.

“But who is the mouse—that’s not decided yet.”

The line fell silent for about five seconds after Milan finished. Isabel could hear the faint current noise on the line—and Milan’s steady breathing.

“You’re saying—Lu Yuan isn’t prey?”

“I’m not saying he’s prey. I’m not saying he isn’t. I’m saying—” Milan paused. Isabel thought she heard a soft laugh from him—not mockery, more like a weary self-deprecation. “You all think this game only goes in one direction. But directions can change.”

“Milan, what exactly do you want?”

“I want to see who finally presses the button.”

The line went dead.

Isabel set the receiver back on the base and stared at it for several seconds. Outside the window, the Berlin sky remained leaden; the tip of the distant television tower was swallowed by low clouds, like a severed finger.

She remembered the first time she met Milan Vojnović, three years ago. It had been at an international communication standards conference in Geneva. Milan had given a keynote speech on Starlink’s third-generation network architecture. After the speech, Isabel had pushed through the crowd and intercepted him in the corridor. She was still working in the EU Commission’s digital competition division at the time, drafting an initial regulatory framework for Starlink, hoping to extract some technical details from him.

Milan had stood through her questions and then said something she still remembered vividly:

“Every regulatory framework you’re thinking of, I’ve already thought of. Most of them I’ve already implemented in the system. If you don’t believe me, go check the routing policy at Starlink’s Frankfurt data exchange node—you’ll find I’ve already designed the network paths for European data localization storage. Technology always runs ahead of the law. You can’t catch up.”

He had turned and walked away, leaving her alone in the corridor.

It was a kind of suffocation she had never felt before—not based on power or status, but on something deeper: this person had thought ahead of everyone. Not by one step, but by an entire dimension.

Now, four years later, she felt she was standing in that corridor again. Milan was still ahead of everyone—including her.

But she did not show her uncertainty.

She opened a new encrypted window and began typing. The recipient: the Data Party’s Brussels liaison node’s anonymous address.

「Farhan: Milan already knows about your new recruit—Lu Yuan. He told me himself. Also, Milan said something that made me uneasy. He said this isn’t a mousetrap—or that the roles of cheese and mouse haven’t been determined yet. Do you know what he’s talking about? — Isabel」

She sent the message. Then she closed that window, opened her work interface, and shifted her attention to this morning’s hearing materials—a “voluntary” pricing transparency report about Starlink’s operations in the European market. The report used mountains of data to prove that Starlink’s pricing strategy was fair, reasonable, and transparent.

Isabel skimmed after a few lines. She had been standing behind the curtain of these numbers for too long. It was hard to treat it as a real wall anymore.

Shenzhen, three stories underground.

Lu Yuan did not know about the conversation between Milan and Isabel. He did not know that in Berlin, a pair of eyes was watching his signature file through encrypted email. He did not know that in the less than two hours since he joined the Data Party, his name had been transmitted and analyzed across three different channels.

He was doing something more urgent.

Lu Zijing sat on a folding chair, her little face flushed with an unhealthy red—not a fever, the after-effect of a violent coughing fit after waking up. She curled her legs on the chair, her small hands wrapped around a thermos Lu Yuan had taken from the base’s rest area, drinking warm water in small sips.

Lu Yuan crouched in front of her and felt her forehead. Temperature normal. Breathing rate normal. Pupils normal. After silently confirming these metrics, he turned his attention to the object Farhan was handing him—an unremarkable black metal box, about the size of a shoebox, with an SMA connector at each end. A dove emblem was laser-engraved on the casing.

“Amina’s pigeon sent it from Lagos. Ground route—Morocco, Spain, France, Germany, finally hitched a ride in the cargo hold of a freight flight from Frankfurt to Shenzhen.” Farhan patted the surface of the metal box. “The latest SkyWalker protocol firmware sample. Her people ran a preliminary validation on a five-year-old FPGA development board at their base. The results were better than expected. The side channel bit error rate is nearly two orders of magnitude lower than the simulation environment.”

Lu Yuan took the metal box, turned it over to check the bottom—the thermal pad showed wear marks, a small patch of residual flux near the screw holes near a circuit board. He did not look for long, but Farhan noticed the order of his inspection: ports, heat dissipation structure, shielding thickness, seam waterproofing.

“This casing was hand-soldered,” Lu Yuan said.

“Yes. Lagos has limited conditions, but they have a very skilled welder—Amina herself. She used to be a submarine fiber optic cable engineer. Soldered tens of thousands of connectors. Steadier than a machine.”

Lu Yuan did not speak. He imagined a woman in her sixties, in some room without air conditioning in Lagos, wearing reading glasses, using a soldering iron to stitch together, stitch by stitch, a device that could be used to shake the foundations of the Starlink empire. The solder joints were smooth, uniform, carrying the texture of a handmade craft.

He held the device, a feeling rising in him that he could not name. Not fear. Not excitement. More like stepping onto a solid stone.

This thing was real. The protocol existed. The side channel was usable. It was still rough, still fragile—like a slingshot in the hands of an infant standing before Starlink’s vast network architecture. But it was real.

“When can we run the test?”

“When your daughter is asleep.” Farhan glanced at the child. “She’s coughing. The air circulation system here isn’t great. I’ll set up a standalone air purifier in her corner. Do you want to—”

“No. She stays beside me.”

Farhan nodded and did not insist. He turned and walked to the test bench, beginning to warm up the device that simulated a Starlink ground station signal generator. On the silver-gray instrument panel, a row of LED indicator lights lit up in sequence, like the slow opening of some ancient creature’s eyes.

Lu Yuan carried his daughter to a small folding cot beside the workstation—another base member had given it up, saying “Let the kid lie down comfortably.” He covered her with his own jacket. The little girl closed her eyes, her breathing carrying a faint tracheal sound. Her hand slipped out from under the jacket, unconsciously grabbing the corner of Lu Yuan’s shirt.

Lu Yuan did not put her hand back. Let it hold on.

He sat down at the test bench and began checking the SkyWalker protocol firmware source code line by line. The C language code arranged in rows on the blue-black background—syntax he knew well—but every line he read described a system he did not fully recognize: a protocol stack parasitic within Starlink’s body, transmitting data through microscopic fluctuations in photon arrival time differences.

In the gaps between reading code, his peripheral vision occasionally caught his daughter’s face. She coughed twice in her sleep, turned over, and quieted again.

Lu Yuan closed his eyes.

On the monitor before him, a line of core QKD channel modulation parameters was waiting for his confirmation. If he entered his name below—not a signature, but a validation code—the first global live test of the SkyWalker protocol would enter its countdown. He entered the validation code. His finger hovered above the Enter key for half a second.

Then he pressed it.

The status bar on the screen jumped from “WAITING_FOR_AUTH” to “ACTIVE.”

Lu Yuan did not look back at his daughter.

He could not look back now.

What he did not know was that on the folding cot less than two meters away, five-year-old Lu Zijing was not fully asleep. Her eyelashes trembled slightly, half her face buried in the collar of her father’s jacket. In the faint light from the ventilation duct, she watched her father’s back—that silhouette sitting before the test bench, shoulders leaning slightly forward, the screen’s glow reflected on his face.

She did not know what her father was doing. But she knew that silhouette was different from before.

She did not make a sound. There were too many things she did not understand. But there was one thing she had learned very early: some questions could not be asked. Asking would make Daddy sadder.

She closed her eyes.

In this windowless space three stories underground, no one could see the sky above. But at this moment, at low Earth orbit altitude, a Starlink satellite numbered STK-43182 was silently crossing the terminator above Shenzhen. Its optical sensors could not record Lu Yuan’s presence. But its QKD module was exchanging quantum keys with its neighboring satellites at a rate of hundreds of millions of entangled photon pairs per second. Among those keys, a tiny fraction—invisible to the human eye, undetectable by routine inspection—was carrying information that did not belong to Starlink’s billing system.

SkyWalker’s first live data packet.

It was very small. Only 128 bytes.

But it was flying.
