Chapter 20 · The Moment of Disconnection
When the first assault vehicle stopped at the building’s south entrance, the lights in the base went out simultaneously.
Not a passive power failure — it was the last automated defense Farhan had set before leaving: when the perimeter vibration sensors detected heavy vehicles approaching above threshold, the main power was automatically cut, and backup lighting switched to the invisible spectrum. In 0.3 seconds, the third underground level sank from a man-made daylight into a space between darkness and deep gray, with no sense of direction.
Lu Yuan stood less than two meters from his daughter. He didn’t move. His eyes would need about twenty seconds to adjust to this light, but he didn’t have that kind of time — he crouched directly, reaching from memory to find the edge of the folding cot, then the edge of the blanket, then his daughter’s shoulder. She was still asleep. Breathing steadily.
He gently pressed his hand on her back, confirming her heart rate was normal. Then he stood up and turned toward the tunnel entrance.
The iron door of the entrance was already half open. Farhan stood in the shadows, carrying a black shockproof case. His body blocked the only faint light coming through the tunnel, rendering him as a sharply outlined silhouette in the dim base. His voice was very low, but in the extreme acoustic silence of the third underground level, every word struck like a drum:
“They’re entering from three directions simultaneously. South entrance — four vehicles. East alley — two. Street front — at least twelve approaching on foot. Confirmed armed personnel count between twenty-five and thirty. We’re out of time.”
When he said these words, his tone was identical to when he reported debugging results. Lu Yuan had learned to recognize Farhan’s signal characteristics under extreme pressure — his voice would become steadier, his speech rhythm more uniform, all emotions compressed below the vocal cords, leaving only data and logic flowing on the surface.
“Sister Shen takes Zijing through the freight elevator passage,” Lu Yuan said. “That exit doesn’t have her signal profile — she’s not a Data Party member, no RF fingerprint in the target files. You and I take the underground tunnel, draw their attention.”
Farhan showed no hesitation, no confirmation. He simply turned, pushed open the iron door of the tunnel with one hand, and disappeared behind it.
Lu Yuan didn’t follow immediately. He crouched beside the folding cot, found his daughter’s calf in the darkness — through the blanket, he could feel her body heat. He took something from his pocket and placed it beside her pillow. It was the wooden elephant he had brought back from Lagos — ebony, its trunk raised upward, lines淳朴. He didn’t speak. In the darkness, he lowered his head, pressing his forehead against the back of his daughter’s hand that gripped the blanket edge, staying there for about two seconds. Then he stood up and turned toward the tunnel entrance.
He paused at the door and looked back. His daughter’s figure had been completely swallowed by the darkness; he couldn’t see her. But Sister Shen’s voice came from that direction, like a line with weak but stable signal: “I’ll take care of her.”
Lu Yuan didn’t answer. He sidled through the half-open iron door of the tunnel and let it close silently behind him.
There were no lights in the tunnel.
Farhan walked about five paces ahead, the outline of the black shockproof case moving like a darker patch in the pitch-black darkness. Lu Yuan followed behind him, the fingertips of his left hand brushing along the rough surface of the tunnel wall — a detail he had remembered after studying the abandoned data center’s construction drawings: every three meters, the wall had a vertical expansion joint. He could estimate distance by counting the joints. Twenty meters. Thirty-five meters. Fifty meters. According to the construction drawings, the tunnel was seventy-three meters long, ending at an abandoned pump room with an iron grate door leading to a surface drainage channel.
At sixty-eight meters, Farhan stopped.
Lu Yuan stopped too. In absolute darkness, any unanticipated change in movement was a signal. Farhan didn’t speak, but Lu Yuan heard an extremely faint sound from ahead in the tunnel — not footsteps, not voices, but the vibration of a mechanical device unlocking. Like a key inserted into a lock, turning.
Not from the tunnel’s end. From the other side of the tunnel wall.
The assault team had entered the building’s underground level. The only thing between them and Farhan and Lu Yuan was about forty centimeters of reinforced concrete.
Farhan began moving again — faster than before, but with shorter steps and less noise. He no longer traced the wall for navigation; he had memorized every seam of this tunnel in his spatial memory, and walking in darkness made little difference to him.
Seventy-three meters.
Tunnel end.
The iron grate door of the pump room was just ahead — through the gap at the door’s edge, an extremely faint light leaked in, from the city streetlights above the drainage channel, filtered through the rainwater grate, reduced to a beam of gray light cut into fine stripes, spilling across the dusty cement floor of the pump room.
Farhan’s fingers touched the lock on the iron grate door. He didn’t open it immediately. He turned his head sideways, pressing his ear to the door crack, listening for three seconds.
No unusual sounds outside.
He twisted the lock and pushed open the iron grate door. The hinges hadn’t been oiled in a long time and let out a short, animal-like metallic groan, unusually harsh in the narrow pump room.
But no one responded to the sound.
Lu Yuan followed Farhan through the iron grate door and into the drainage channel. The channel bed was dry — only a shallow layer of silt and fallen leaves, soft and almost soundless underfoot. The walls on both sides were covered in dark green moss, the air thick with the mixed smell of earth, wastewater, and decaying organic matter. The rainwater grates overhead were spaced about ten meters apart, each casting a beam of gray-white streetlight into the dark channel, forming a string of evenly spaced light patches like a railway track of light, extending toward a turn at the edge of sight.
They followed the drainage channel for about fifty meters. Farhan stopped at the second turn, looked up through a grate for about ten seconds, then retreated. His voice produced a faint echo between the drainage walls:
“There’s an alley above the grate. No monitoring signals — they deployed two mobile base stations at the alley entrances, but there’s a coverage blind spot about seven meters long in the middle of the alley. We can surface there, and then —”
He didn’t finish.
The grate overhead let out a violent metallic clang — like someone stepping on a heavy iron plate. Then a muffled voice, very low, but too close — coming through the grate’s gaps, still清晰:
”— the third underground level is empty. They’ve run. The iron grate door toward the pump room is open —”
Farhan stopped speaking. He grabbed a rusted iron pipe on the drainage wall and began climbing upward. The pipe groaned unpleasantly under his weight but didn’t break. His feet found purchase twice on the slippery moss. Lu Yuan climbed below him, using one hand to support the bottom of the shockproof case to help him balance.
Farhan’s head reached the underside of the grate. He didn’t push it open immediately — he first listened sideways for sounds above. The alley had no footsteps, no voices. The voice earlier had come from a grate farther away — they hadn’t discovered this exit.
He pushed upward.
Rainwater grates in the city were usually welded shut. This one wasn’t welded — just rusted. Farhan’s first push didn’t budge it. The friction between the rusted iron frame and the cast-iron grate, accumulated over years, had reached a level requiring more torque than human strength could provide.
Farhan didn’t try a second time. He reached into his pocket and pulled out a device the size of a cigarette pack — a low-frequency vibrator. He pressed it against the edge of the grate and flipped the switch. The device emitted a buzzing sound similar to teeth crushing hard candy, lasting about two seconds. Rust particles shook loose from the grate’s edges.
Then he pushed upward again.
The grate let out a hoarse metal shriek, like being forcibly awakened from a deep sleep, lifting at one corner. Farhan squeezed sideways through the gap, then lay flat on the alley pavement, reached back, and pulled Lu Yuan up.
They stood in a narrow alley less than two meters wide. The walls on both sides were the gable ends of residential buildings, one gray and one white, densely covered with air conditioner units and rusted pipes. Both ends of the alley were lit by streetlights, but the middle section fell between the coverage of two lamps — the blind zone Farhan had predicted. He was right.
A series of rapid footsteps came from one end of the alley — not approaching them, but still very close. Farhan tucked the shockproof case under his arm, moved north along the wall, walking quickly but not running — in a city at night, running would attract attention, but brisk walking wouldn’t.
Lu Yuan followed him, exiting the narrow alley onto a roadside bike path.
The street was nearly empty. Shenzhen in the early morning hours, except for the occasional nighttime freight tricycle and street sweeper, the entire city breathed in silence. Streetlights cast the shadows of roadside trees across the sidewalk like an ink drawing on uneven paper.
They walked about two blocks. Farhan stopped behind a bus stop advertisement board, crouched, opened the shockproof case, and took out a preconfigured encrypted terminal. He pressed the power button.
The screen lit up. A line of green text appeared on a pure black background.
「Pigeonnet · Forward Node 7 · Link status: Normal · Awaiting input」
Farhan’s fingers typed one line ofcommand on the keyboard — not the command to start the injection program, but a set of coordinates. A new work location. Then he closed the shockproof case, stood up, and turned to Lu Yuan.
His expression, under the streetlight, showed a combination Lu Yuan had never seen on his face before — the peak of exhaustion coexisting with something reignited, like a furnace that had burned too long and was nearly extinguished, suddenly receiving a bucket of new fuel.
“Your daughter — Sister Shen took her to a safe point. Pigeonnet line confirmed. They’ve arrived.”
Lu Yuan stood at the edge of the bus stop. A night breeze came from the end of the street, carrying the particular humidity and faint saltiness of southern coastal cities, passing over his exposed skin. He felt his hands trembling — not from fear, but from his body beginning to release all the accumulated tension, now that it realized it was safe.
He didn’t say thank you. He knew Farhan didn’t need it.
“Milan,” Lu Yuan said. “What did he do?”
Farhan didn’t answer immediately. He looked down at the shockproof case. Then, under the streetlight, he said one sentence — very quietly, but every word seemed precisely weighed before release:
“I don’t know. But Silas’s assault team received a retreat order three minutes before we entered the drainage channel.”
Lu Yuan looked at him.
“What?”
“Retreat order. From the top of the command chain — authorization code A0, an emergency code second only to the CEO himself. Message content: ‘Targets have relocated. Class A false alarm. Withdraw.’ Silas tried to disobey — but an A0 code is不可反驳 under Starlink’s tactical execution protocol. Any field commander receiving an A0 order who fails to execute will have their command authority automatically transferred to the nearest authorized node within fifteen seconds.”
Farhan paused, like confirming a judgment he himself wasn’t entirely sure of.
“Milan used that code,” he said. “Only he and the CEO know it. The CEO is currently in Singapore at a closed-door meeting that cannot be interrupted — impossible for him to issue a tacticalcommand at 4:00 AM. So it could only be Milan.”
Lu Yuan stood under the streetlight, running Farhan’s words through his mind. He felt his analytical capacity slowly returning — switching from the pure survival instinct he had used in the drainage channel back to normal logical processing mode.
Milan had issued the A0 command. Milan had canceled Silas’s assault operation. Milan had used anirrevocable authorization code to stop that encirclement at the last minute.
But Milan had told no one.
No notification to the Data Party. No notification to Lu Yuan. No explanation left for himself — he had directly used the highest authority to modify an executing A1-level interdiction operation, which would leave a permanent record in Starlink’s internal audit system. Anyone reviewing this record at any time would see that Milan Vojnović, at 4:03 AM, had used his own authorization code to cancel the authorization order he had signed four hours earlier.
He was both the signer of the arrest warrant and the signer of the release order.
Lu Yuan closed his eyes. Behind his shut lids, he didn’t see darkness — he saw Milan sitting in that Belgrade office. Perhaps in that moment, Milan had finally understood: he wasn’t choosing between Starlink and the Data Party. He was choosing between protecting the system itself and preventing a five-year-old child from being harmed by his system.
He chose the child.
It might not have been because that child was Lu Yuan’s daughter. It might have been because — that child was the same age as Mia had been.
“He doesn’t know where my daughter is now,” Lu Yuan said. “When he called off the strike — he didn’t even know if she was safe yet. He just made the decision to stop the operation at a time when she might still have been inside that building.”
Farhan didn’t speak. But he nodded slightly. On this early morning city street, two men who had just escaped an encirclement stood under a streetlamp, in a silence neither of them had expected, confirming a conclusion neither had anticipated:
Milan Vojnović had cut the chain.
When Silas called Milan’s phone, the time in Belgrade was 9:47 PM.
Milan answered the phone and didn’t speak. He held the receiver to his ear, leaned back in his chair, listening to the breathing coming through the line — Silas’s breath,压抑 to the point of nearly fracturing.
“Do you know what you’ve done?” Silas’s voice was very low. So low that Milan almost couldn’t recognize it as anger — more like the sound of something frozen to itslimit.
“I know.”
“Do you realize you signed that authorization order four hours ago and revoked it four hours later — what kind of record you’ve left in Starlink’s internal audit system? You’ve essentially told everyone that you signed an A1-level operation, then overturned your own order with an A0 password at the last minute before execution. No reason. No supplementary explanation. No error report. A chief architect signing and revoking the same order on the same night — to the security committee, that means only two possibilities: either you’ve been compromised, or you’re protecting the targets.”
Silas stopped, waiting for Milan to deny it. But Milan said nothing.
“You are protecting them.” A tiny, nearly invisible crack appeared in Silas’s voice, like the sound before the first fissure appears on an ice surface. “You’re protecting that Chinese man and his child. Don’t think I don’t know why — your daughter —”
“Silas.”
Milan’s voice came from the other end. He didn’t raise his volume, didn’t increase his speed, but Silas stopped anyway.
“If you mention my daughter one more time,” Milan said, his voice calm as a stone that had rested at a river bottom for a long time, all edges smoothed by the current, “I will submit to the CEO a complete audit log of your global data black market — including the three unauthorized token resale channels you established in Singapore, Bangkok, and Lima; the transfer records of seven shell companies you registered in Hong Kong; and the private communication archives you obtained through Starlink Security Center surveillance backdoors for extorting Southeast Asian political and business figures. All preserved. Complete. Spanning from your first year of employment to the present.”
Complete dead silence fell on the line.
Milan didn’t give him a chance to respond. He continued, his tone unchanged: “You always thought your operations were unrecorded because you had the highestpermissions to clear audit logs. But you forgot — the Entry-7 protocol has more than one audit output port. There’s another one. One you don’t have permission to see.”
He paused.
“I designed the system, Silas. Did you think I designed it to monitor ordinary users?”
Silas’s breathing on the other end of the line became uneven. Not fear — it was his body’s instinctive response to having his entire hand exposed.
“You couldn’t have —”
“June 2053, Bangkok. You accessed a non-existent QKD channel through a钻-certified terminal — the metadata record of that channel isn’t in the standard audit system, but it left a copy in the Entry-7nested entry point cache. Not the content. Just the fact of the connection. Time, location, terminal ID. Seven records. All in my private directory.”
Silas didn’t answer. He couldn’t answer, because every detail Milan had said was true. He had thought his activities in this system were completely untraceable — because he had the highest authority over the Asia-Pacific Security Center, because he could clear audit logs after every operation, because he had ensured that none of his steps in the system could be discovered byconventional review.
But Milan had designed the system before he had those authorities.
Milan hadn’t started tracking him after his operations began. Milan had already embedded the interfaces to track people like Silas into the system’sunderlying architecture when he designed the Entry-7 protocol six years ago. Like a designer pre-routing a pipe known only to himself inside a wall while building a house — not for his own use, but for the day when he would need to pull someone’s crimes out of that wall.
“So that authorization order —” Silas said.
“Was a test.”
“Test what?”
Milan didn’t answer. But he didn’t hang up the phone either. He let Silas wait on the line for about five seconds, then said one final sentence: “To test whether you would go after a five-year-old child.”
He gently placed the phone back on its cradle. The crisp click of the receiver meeting the base in the quiet office sounded like a period being set.
Outside the window, sparse lights glimmered on the opposite bank of the Sava River. Milan sat in his chair for a while, then picked up his phone — he saw the message Lu Yuan had sent about the wooden elephant, already several hours old. He hadn’t replied. But he hadn’t closed the message either.
He left it on the screen.
Shenzhen, 4:30 AM.
Lu Yuan didn’t return to the base. The base was alreadysealed off, and although the assault team had withdrawn, Silas’s people might have left long-term surveillance devices in the surrounding area.
Farhan contacted Pigeonnet’s last backup node in Shenzhen through the encrypted terminal — an apartment in a village-in-the-city in Bao’an District, belonging to someone who had never appeared on any Data Party list. The receiving address was a text message with just three characters: 「Old place.」
The apartment was on the fifth floor of an old building with no elevator. The paint on the security door had blistered and peeled, the doorframe marked with scratches of varying depths made by keys. Lu Yuan knocked three times — the signal Farhan had specified: three knocks, intervals increasing from short to long.
The door opened. Standing at the entrance was a man who looked under thirty, wearing a T-shirt washed white at the collar, his hair slightly messy, a pair of thick-framed glasses on his nose. He glanced at Lu Yuan, then at Farhan, and stepped aside.
“Come in. The router password is on the fridge door. The sheets were changed last week.”
He asked no questions. He didn’t ask who they were, why they were here, or when they would leave.
Lu Yuan walked into the apartment. The room was not large — about forty square meters, furnished with near-ascetic simplicity: one bed, one desk, one chair, one simple wardrobe. On the desk sat a desktop computer, the screen on, showing a command-line terminal, a cursor blinking silently at the bottom of the screen. The curtains were drawn tight.
Lu Yuan sat down at the desk. He opened the encrypted terminal Farhan had handed him, connected to the WiFi password taped to the fridge door, and opened the Pigeonnet command-line interface.
A new message appeared on the screen. From the Lagos node’s encrypted channel, the sending timestamp showed about ten minutes ago. The sender was Amina.
The message was very short:
「First batch of storage cards has passed the Tamanrasset checkpoint. Four hours ahead of schedule. Gray Dove never stopped. — Amina」
Lu Yuan stared at the message for a while.
Then he did something Farhan hadn’t predicted. He turned around and lay down on the bed beside the desk — not to sleep, but face up, staring at the unlit ceiling light, motionless for about half a minute.
Then he closed his eyes.
“I’ll sleep for twenty minutes,” he said. “Then wake me up. I’ll take over the remaining compilation work — you still owe me four to five hours of time compression.”
Farhan didn’t stop him. He just sat in the only chair, placed the shockproof case on his lap, opened the lid, and began checking whether the hard drive inside had suffered any physical damage during their escape. His movements were quiet and precise, like a calibrated machine performing routine checks.
Outside the window, Shenzhen’s sky was transitioning from the darkest deep blue to a color between gray and light blue — not dawn, but the quietest period before dawn. The streetlights were still on, but their light had begun to seem less important. An early-rising cleaner was sweeping the street below, the sound of the broom brushing across the asphalt filtering through the walls — a rustling, continuous sound, like some kind of time-stretched breathing.
The apartment’s window faced the end of a narrow alley. At the alley entrance, a streetlamp was still lit. Not far from the streetlamp stood a utility pole with a poster for free Starlink service, most of it already torn away by wind and rain. The smiling white-collar woman on the poster had been faded by rain, leaving only one hand still pointing to the upper-right corner of the image — pointing in a direction Lu Yuan couldn’t see.
Lu Yuan lay on the bed with his eyes closed. He didn’t know if he could actually fall asleep. But he knew that in these twenty minutes, he needed to let his body and brain stop — even if only on the surface. Like a hard drive spinning at high speed, letting the read head return to the starting position before writing the next sector.
The city was slowly waking outside the window. In distant places — at the edge of the Taklamakan Desert, or on a road in the Sahara, or in a Belgrade office with its lights still on — others continued their journeys. The line was still extending, and someone was re-soldering the broken interface.
Lu Yuan didn’t know about those things. He only knew that his daughter was alive. Milan hadn’t pressed that button. He still had a little over thirty hours.
At the edge of fading consciousness, he seemed to see the wooden elephant — lying quietly beside his daughter’s pillow, its trunk raised upward, maintaining that silent and certain posture in the darkness.
Like a coordinate that would never change direction.
