Secrets in the Key and Su Ying's Investigation

Lin Xiao stood by the window, his fingers unconsciously tapping the sill. The simulated starlight reflected tiny points of light in his eyes. The communicator screen had gone dark; Su Ying's reply had already arrived. He turned back to his desk, took the metal key from his inner pocket, and examined it carefully beneath the desk lamp. The patterns cast subtle shifting shadows in the light, while the engraved numerical code was sharp and deep. Outside the window—outside the virtual window—a "shooting star" streaked across the night sky, trailing a brief tail of light. Lin Xiao closed the key in his palm, its icy touch gradually replaced by his body heat. He needed to find an absolutely secure place to examine the "old things" Fletcher had left behind. But before that, he had to make sure Su Ying could understand what she was about to see—not the whole truth, but at least enough for her to keep moving forward at his side. Faint footsteps sounded in the corridor outside, drawing nearer. Lin Xiao slipped the key back into his inner pocket, composed his expression, and waited for the knock.

Three evenly spaced knocks sounded.

"Come in."

The door opened, and Su Ying entered. She wore training clothes, the dark gray fabric blotched in several places with sweat. Her hair was tied into a neat ponytail behind her head, with a few loose strands clinging to her temples. Her breathing had steadied, though her cheeks still held the flush of exertion. The distinctive smell of the training grounds—rubber mixed with sweat—entered with her, briefly mingling with the scent of electronic equipment in the office.

"What is it?" Su Ying shut the door and walked to the desk. Her gaze swept across its surface before settling on Lin Xiao's face, keenly catching the unusual focus in his eyes.

Rather than answering immediately, Lin Xiao took a palm-sized black metal box from a drawer. There were no markings on its surface, only a ring of tiny cooling vents around its edges. He pressed a button on the side, and the lid slid open soundlessly, revealing a complex array of ports and a small display.

"This is the base's highest-level portable data isolation terminal," Lin Xiao explained. "It has an independent power supply and physically blocks all wireless signals. It can only read storage devices through a wired connection. If it detects any attempt by an external signal to connect, it will immediately trigger its self-destruct protocol."

Su Ying raised an eyebrow slightly. She had seen plenty of classified equipment, but few designs this extreme. "What are you looking at?"

Lin Xiao removed the key from his inner pocket and placed it on the desk. The metal reflected a cold, hard gleam beneath the light. "Fletcher gave it to me. He said there were some 'old things' inside that might be useful to us."

"Fletcher?" There was obvious wariness in Su Ying's voice. "That bureaucratic supervisor? He suddenly decided to be kind?"

"He changed," Lin Xiao said briefly. "Or rather, certain things forced out who he really was. I still don't fully understand why, but when he gave me the key... it felt like he was entrusting me with his last affairs."

Su Ying fell silent for several seconds, her eyes shifting between the key and Lin Xiao. Finally, she nodded. "What do you need me to do?"

"I need you here," Lin Xiao said. "As a witness, and as... insurance. If there's a trap in the key, or if reading it triggers an alarm, I need someone who can react immediately."

"Understood." Su Ying went to the door and locked it from the inside. Then she returned to the desk, pulled over a chair, and sat down. Her posture was relaxed, yet ready to explode into action at any moment. Her hands rested naturally on her knees, her fingertips only inches from the dagger concealed against the outside of her thigh.

Lin Xiao inserted the key into the isolation terminal's dedicated port. The fit was perfect, and the metal made a faint click as it connected. The terminal screen lit up, and a blue progress bar began to move slowly. Only the low hum of the terminal's cooling fan and their soft breathing remained in the room.

Three minutes later, the progress bar reached the end.

A simple directory interface appeared on the screen, listing three folders: [Files], [Data], and [Equipment]. Each folder displayed its storage capacity and last modified date—the oldest document dated back fifteen years.

Lin Xiao opened the [Files] folder first.

It contained dozens of scanned documents. The resolution was poor, and some pages still showed shadows left by the scanner along their edges. He opened the first one, and a hand-drawn chart appeared on the screen. It had been drawn in black ink, its lines neat but slightly stiff, clearly the work of many years ago. In the center were the words "Hydra Internal Faction Relations (1998–2003)," with more than a dozen branches radiating outward. Each branch ended in a name, a position, and a brief note.

"White—Radical Faction, advocates accelerated infiltration, connected to the 'Winter Plan.'"

"Pierce—moderate faction, long-term infiltration strategy, controls S.H.I.E.L.D. resources."

"Lister—technical faction, focused on biological enhancement, maintains private contact with A.I.M."

"Zola, after digitization—algorithm faction, advocates controlling society through data, no longer possesses a physical body."

Lin Xiao scrolled down, and the chart extended with more details. Some names were familiar to him—Alexander Pierce, Hydra's highest-ranking infiltrator within S.H.I.E.L.D.; Arnim Zola, the mad scientist who had digitized his consciousness. Other names were completely unfamiliar, but the notes beside them sent chills down his spine: "Participated in Eastern European human trafficking networks," "Conducted arms deals with the Ten Rings," "Performed illegal human experiments in Africa."

"This is..." Su Ying's voice came from beside him, her shock tightly restrained. "Hydra's internal structure?"

"More than that." Lin Xiao enlarged one corner of the chart and pointed to a connection marked with a red dotted line. "Look here. The White faction and the Lister faction had a secret partnership, but the note says, 'Partnership strained. White attempting to absorb Lister's biological enhancement program.' That means Hydra wasn't a unified block. Its factions were also tearing at each other."

He continued through the other documents. Several were investigative summaries on S.H.I.E.L.D.'s early organizational structure, recording its initial departmental setup, personnel staffing, and resource allocations. The information itself was not especially classified, but several annotations mixed in were valuable: "Howard Stark suspected of retaining some Tesseract research materials without turning them over," "Peggy Carter expressed concerns in her later years regarding S.H.I.E.L.D.'s direction," "Several early recruited agents had questionable identities."

But what truly made Lin Xiao's breath catch was the final document.

It was a scan of yellowed paper, its edges scorched. The writing had blurred somewhat with age. Its title consisted of a single line: "Rumored Records Concerning Project TAHITI (Unofficial Source)." The body was brief, more like an intelligence summary:

"According to an unreliable source, S.H.I.E.L.D. possesses a highly classified internal project codenamed 'TAHITI.' The project involves a form of 'life restoration technology,' allegedly connected to extraterrestrial evidence recovered in 1945. Security level: Level 10, the highest. The circle of informed personnel is extremely small. All related records are stored under physical isolation and are not connected to any network. Note: This technology is suspected to have severe side effects and may cause mental collapse or memory disorder in subjects."

Beside the passage was Fletcher's handwritten note: "Possibly involves resurrection technology. Extremely high classification. Connected to extraterrestrial evidence? Further verification needed, but risk too great. Temporarily shelved."

The room was so quiet that the terminal fan's hum could be heard.

Su Ying stared at the screen, her brow deeply furrowed. "Project TAHITI... resurrection technology? It sounds like science fiction."

"It isn't science fiction." Lin Xiao's voice was soft, but every word was clear. "S.H.I.E.L.D. really did have such a project. And... they succeeded."

He did not continue. In his memories, Agent Phil Coulson had died in the Battle of New York, only to be revived through Project TAHITI. The process had been painful, and the side effects severe, but it had succeeded. This document confirmed the value of Fletcher's intelligence, as well as another fact: Fletcher's position within Hydra ran far deeper than he had let on. Otherwise, he could never have come into contact with rumors at this level.

"Keep going," Su Ying said, her voice now carrying a trace of gravity.

Lin Xiao closed the files folder and opened [Data].

Inside were virtual images of three encrypted hard drives, each requiring a separate password. Fortunately, Fletcher had left a text file in the key's storage space containing three sixteen-digit passwords. Lin Xiao entered them one by one.

When the first hard drive unlocked, a world map appeared on the screen. Hundreds of red dots densely covered it, each marked with a brief code and date. Lin Xiao enlarged the map over Europe and randomly selected a coordinate in Berlin. Detailed information appeared: "Safe house codename 'Nightingale.' Activated March 1997. Last maintenance record November 2005. Status: suspected abandoned. Note: three underground levels, stocked with basic survival supplies and communication equipment. Entrance disguised as an old bookstore."

"Hydra's global safe house network," Su Ying said quietly. "Some may already be defunct, but as long as we have the coordinates, we can send people to verify them."

Lin Xiao scrolled across the map. The red dots spanned every major continent—New York, London, Moscow, Tokyo, Cairo, Rio de Janeiro... Some were marked "active," some "dormant," and more were listed as "abandoned" or "status unknown." Even so, the value of this coordinate list was incalculable. It meant the Continental Hotel could rapidly establish footholds worldwide, using these existing facilities to save enormous amounts of time and resources.

The second hard drive contained transaction records. Spanning from the 1990s to the early 2000s, they documented Hydra's dealings with various underground organizations. The name that appeared most often was the Hand—an ancient ninja organization involved in arms trafficking, drugs, and human trafficking. The transactions covered everything from Vibranium smuggling to biochemical weapon materials, hired assassins to intelligence exchanges. Every entry meticulously listed the time, location, representatives of both parties, and detailed descriptions of the goods or services.

"Look here." Lin Xiao pointed to one record. "In 2002, Hydra, represented by White, purchased 'twelve genetically modified children' from the Hand, represented by Madame Gao. Their stated purpose was 'reserve personnel for the Winter Plan.'"

Su Ying clenched her fists. Her knuckles turned white from the force.

"And here." Lin Xiao scrolled down the page. "In 2005, Hydra provided the Hand with 'three cases of Extremis Virus prototype samples' in exchange for 'preliminary coordinates to the entrance of K'un-Lun.'"

"K'un-Lun?" Su Ying asked.

"A legendary place." Lin Xiao did not elaborate. "What matters is that these transaction records prove Hydra and the Hand had a long-term, deeply rooted partnership. If we have to deal with the Hand in the future, this information will allow us to anticipate their operating patterns and resource channels."

The third hard drive was the smallest, but its contents concerned Lin Xiao the most.

It contained several audio files with garbled filenames, each between thirty seconds and two minutes long. Lin Xiao opened the first.

The recording began with crackling static, followed by a heavily distorted voice. It sounded as though it came through a voice changer, mechanical and flat. "...The base model of the Zola Algorithm has passed testing. Fed global conflict data from the past seventy years, it achieved a prediction accuracy of 92.3 percent. The next step is connecting it to real-time surveillance networks, including satellites, cameras, communication records, social media..."

Another voice interrupted. It was similarly altered, but more urgent in tone. "The risk is too great. Once the algorithm begins independently filtering 'potential threats,' how can we ensure it won't classify us as targets too?"

The first voice replied, "The algorithm has a whitelist. All Hydra members and associated personnel are within the exemption range. As for everyone else... necessary sacrifices are acceptable for the sake of a greater order."

"But what about S.H.I.E.L.D.? Nick Fury won't just sit by while we establish a global surveillance system."

"That's why we need Project Insight. Three Helicarriers equipped with directed-energy weapons, suspended in low Earth orbit. Once the Zola Algorithm identifies a threat, the carriers can locate and eliminate it within minutes. Fury will support it—as long as we package the plan as a 'global counterterrorism defense system.'"

The audio cut off abruptly.

The room fell into complete silence.

Su Ying's expression darkened. "Project Insight... Helicarriers... global surveillance and immediate elimination... They're insane."

"They aren't insane." Lin Xiao closed the audio file, his voice icy. "This is Hydra's logic. To establish their so-called 'order,' they can sacrifice anyone and monitor everyone. The Zola Algorithm will analyze every person's behavior patterns, social relationships, and ideological tendencies, then predict whether that person might someday 'threaten social stability.' Once someone is marked as a threat, the Helicarriers will fire energy beams from orbit and erase them instantly."

He opened another recording. This one was shorter, only twenty seconds.

"...The Winter Soldier's condition is unstable. The brainwashing program requires regular reinforcement, or memory fragments may resurface. Recommend increasing the frequency of electric shocks, or considering the use of new chemical agents..."

"Bucky Barnes," Su Ying said quietly. She had clearly heard the name before. "Captain America's closest friend. He fell from a cliff and vanished during World War II, but Hydra actually turned him into an assassin."

Lin Xiao did not answer. He merely looked silently at the screen, at the icons for those audio files. These fragmented recordings confirmed far too much—the early concept of Project Insight, the existence of the Zola Algorithm, the Winter Soldier's ongoing control. Why had Fletcher preserved them? For self-protection? Or to use them as bargaining chips at some future moment?

He closed the data folder and opened the final folder, [Equipment].

Inside were several photographs of old spy gear: a Walther PPK pistol, worn but well maintained; a miniature camera and recording device no larger than a button; several passports from different countries, all bearing photographs of Fletcher in his youth but different names; and a ring whose face could be flipped open to reveal a sharp blade.

"They're all old things," Lin Xiao said. "But they've been well maintained. Things Fletcher used when he was younger."

He shut down the terminal and removed the key. The screen went dark, leaving only the glow of the desk lamp in the room. The simulated starry sky outside had shifted into dawn mode, a false pale white beginning to spread along the edge of the deep blue sky.

How much time had passed? Lin Xiao looked at the clock on the wall—3:17 a.m. He had been sitting there for nearly four hours.

He stood and stretched his stiff neck and shoulders. His bones gave a faint crack. Then he began organizing the documents on the desk—stacking the printed faction chart, S.H.I.E.L.D. summary, and Project TAHITI scan neatly one by one; sorting the notes containing safe house coordinates and transaction records; writing the key points regarding Project Insight and the Winter Soldier on separate sticky notes.

The entire process was slow and focused. His fingers brushed over the rough surface of the paper, feeling the faint raised texture left by the ink. His mind raced, integrating, analyzing, and filing away these scattered fragments of information. Project TAHITI confirmed S.H.I.E.L.D.'s hidden trump card; the safe house coordinates provided a foundation for global expansion; the transaction records exposed Hydra's dark network; and the Project Insight audio pointed to the disaster that had to be stopped in the future.

Yet all of it pointed to the same question: How could he explain to Su Ying why a peripheral Hydra officer cared so deeply about these top-secret matters? Why did his plans always so precisely target the greatest threats of the future?

He still had not found an answer.

The door was gently pushed open.

Lin Xiao looked up. Su Ying entered carrying a cup of coffee. Steam curled from the rim, forming a hazy column in the lamp's glow. The bitter aroma of coffee instantly spread through the room, mixing with the ink scent of paper and the plastic smell of electronic equipment. She was no longer in her training clothes, having changed into dark casual wear. Her hair hung over her shoulders, the ends still damp from her shower.

"You haven't slept?" Su Ying placed the coffee beside Lin Xiao's hand, the bottom of the cup making a soft tap against the desk.

"Some things needed organizing," Lin Xiao said, taking the coffee. The cup was warm, its heat passing through the ceramic into his palm. He took a sip. The bitter liquid slid down his throat, bringing a brief moment of clarity.

Su Ying did not sit. She stood beside the desk, her gaze moving over the spread-out documents, the sticky notes covered in writing, and the metal key lying quietly at the corner of the desk. Her eyes paused briefly on each item before moving on, finally settling on Lin Xiao's face.

The room was quiet. The low hum of the ventilation system was the only background sound. The "sky" beyond the simulated window gradually brightened, and false morning light shone through the glass, casting pale blue rectangular patches across the floor.

After a long while, Su Ying spoke softly.

"You know far more than a peripheral Hydra officer should know, Lin Xiao."

Her voice was calm. There was no accusation, no suspicion, only a statement of fact. Yet every word was like a fine needle, gently piercing the calm that had endured in the room for so long.

Lin Xiao set down his coffee cup. Ceramic struck the desk with a crisp sound.

Su Ying continued, her gaze clear and direct. It no longer held only a soldier's sharpness; there was now an element of inquiry and deeply hidden concern.

"From the very beginning, you knew White was a problem. You knew who in the base belonged to the Radical Faction. You made preparations in advance, purged the interior, and established the beginnings of the Continental Hotel. Meeting Fletcher wasn't an accident. You planned it. And now, you've obtained these—" She pointed at the documents on the desk. "Information involving S.H.I.E.L.D.'s highest secrets, Hydra's internal structure, a global safe house network, even... resurrection technology and Helicarrier plans."

She paused and drew a deep breath.

"What exactly... are you planning? Or rather, what are you planning all this for?"

The question hung in the air like a slowly descending blade.

Lin Xiao looked at Su Ying. The desk lamp shone from the side, casting soft shadows across her face. Her eyes appeared dark brown in the light, and deep in her pupils was his reflection. There was confusion there, concern, anticipation, and something he rarely saw in her eyes—trust, and the unease hidden behind it.

She was not interrogating a suspicious companion.

She was asking someone she was willing to trust, yet could not fully understand.

Lin Xiao opened his mouth, wanting to say something. Explain? Conceal? Confess? Countless answers flashed through his mind. Every one had a price, and every one could change the fragile trust that had only just formed between them.

But in the end, he merely remained silent.

The simulated morning light outside brightened a little more. The false sun was about to "rise," and a new day was about to begin—in this deeply buried base, in this world filled with lies and conspiracies.

And the answer still needed time.
