Stark's Reaction and the Ripples at S.H.I.E.L.D.

Lin Xiao set down the empty teacup. The ceramic base made a soft tap against the wooden tabletop. Morning light streamed through the window, illuminating the thoughts settled in his eyes. There was a light knock at the office door, and Nightingale pushed it open, tablet in hand, its screen still scrolling with data.

"Mr. Lin," she said, a trace of tension in her voice. "The activity patterns on Stark Industries' internal network have begun to change. The frequency of security audits has risen by 300% over the past four hours, and..." She turned the tablet toward Lin Xiao. A set of complex traffic-analysis charts filled the screen. "Three anonymous but well-funded accounts are offering high prices on the dark web for any intelligence related to A.I.M. and Aldrich Killian."

Lin Xiao rose and walked to the window. The town remained peaceful in the early morning, but he knew the storm's first ripple had already reached the surface.

"When?" he asked calmly.

"The forty-seventh hour after the information was sent." Nightingale brought up the timestamps. "Stark Industries' biotechnology division began its first internal audit at ten last night and launched a second at three in the morning. The audit covers all external partnership projects, supplier databases, and background checks on every researcher who left in the past five years."

Lin Xiao took the tablet, his finger sliding across the charts. The audit frequency peaked at four in the morning—the time when human vigilance was at its lowest. Stark had chosen that hour because he did not want to alarm too many people, at least not any possible informants inside the company.

"And the intelligence requests on the dark web?" Lin Xiao asked.

Nightingale opened another interface. The screen displayed the dark-themed page of an intelligence-trading platform on the dark web, with the IDs of three anonymous accounts highlighted. Each account had posted at least five bounties in the past twelve hours, covering keywords such as "Aldrich Killian's recent movements," "locations of A.I.M.'s secret laboratories," and "Extremis Virus research progress."

"The bounties are substantial," Nightingale said. "Every piece of intelligence is priced above fifty thousand dollars. The highest—evidence of Killian's contact with extraterrestrial material—is offering two hundred thousand. Payment is in Bitcoin, and the money has already been deposited in the platform's escrow accounts."

Lin Xiao stared at the bounty requests. The offer style was very Stark—direct, efficient, throwing money at every possible obstacle. More importantly, the requests were worded with extreme professionalism. Whoever wrote them knew far more about A.I.M. and Killian than any ordinary information broker would.

"He took it seriously," Lin Xiao murmured.

He returned the tablet to Nightingale and turned back toward the window. Distant mountains drifted in and out of the morning mist beneath a clear pale-blue sky. Early pedestrians began appearing on the town streets, the bakery door opened, and the scent of fresh bread floated over on the breeze.

"Keep monitoring them," Lin Xiao said. "But do not make contact with those bounties. Stark is like a startled spider right now. Touching any strand of his web will provoke a reaction."

"Understood." Nightingale nodded, her fingers moving swiftly over the tablet. "I've placed monitoring tags on the requests. The system will notify us immediately if anyone accepts them or provides intelligence."

She paused, then added, "Also, Stark Industries' cybersecurity team attempted a reverse trace at five this morning. They locked onto a Wi-Fi node at Berlin Central Station, but the trail ended there. JARVIS should have realized the sender used multiple relays and an instant-destruction protocol."

Lin Xiao nodded. It was within his expectations. Stark could not possibly refrain from trying to trace the anonymous sender, but the safeguards Nightingale had arranged were tight enough to delay him for a while.

After Nightingale left the office, Lin Xiao stood by the window for a long time. The sun climbed gradually higher, stretching his shadow across the wooden floor. The office was quiet save for the steady ticking of the wall clock. He could smell coffee drifting through the air—breakfast was probably being prepared in the kitchen downstairs—along with the low, distant chime of church bells.

Forty-eight hours. A full two days since the information had been sent.

Over those forty-eight hours, Tony Stark had gone from initial suspicion to beginning an investigation, from passively receiving information to taking the initiative. The speed was faster than Lin Xiao had expected, but it suited Stark's nature even better—that genius, arrogant Tony Stark who could never endure being kept in the dark.

Lin Xiao walked to his desk and opened a drawer. Inside lay a handwritten notebook containing his memories of the key points in this timeline. He turned to the page marked "2013," his finger passing over the words "Extremis Virus crisis," "Mandarin terrorist attacks," and "Stark Tower destroyed."

Now, those events might never happen. Or perhaps... they would arrive early in another, more dangerous form. The butterfly had already beaten its wings, and the storm was gathering. Lin Xiao felt that familiar pressure—the weight he had felt in his previous life on the eve of the final battle, watching Thanos's fleet close in on Earth. But this time, he was no longer an observer. He was the one beating those wings.

At ten in the morning, a secure communication request from Fletcher came through.

Lin Xiao accepted the video call. Fletcher's somewhat weary face appeared on the screen. He was seated in a moving car, with city streets sliding past behind him. Light outside the window shifted between brightness and shadow, highlighting the wrinkles at the corners of his eyes.

"The situation has changed," Fletcher said without preamble, his voice lowered. "S.H.I.E.L.D. has begun moving internally."

Lin Xiao adjusted his earpiece. "What kind of movement?"

"Counter-infiltration reviews," Fletcher said. "Two levels higher than usual. Headquarters has ordered a renewed review of every 'resolved' incident from the past five years, especially cases involving casualties or intelligence leaks. The review team was appointed directly by Fury and bypassed the regular oversight department."

Lin Xiao's fingers lightly tapped the desk. Once, twice.

"The reason?" he asked.

"I don't know." Fletcher shook his head. "But there are several possibilities. First, Stark's movements may have drawn S.H.I.E.L.D.'s attention. Stark Industries is an important technical supplier for S.H.I.E.L.D., after all, and any unusual activity will be monitored. Second, the previous disappearance of that transport convoy was classified as a gang dispute, but some people in S.H.I.E.L.D. think it was too clean. Unnaturally clean."

He paused and took a drink from a bottle of water beside him. Lin Xiao could hear the car engine rumbling and the faint wail of sirens in the distance. Fletcher was probably in New York, perhaps on his way to a safe house.

"Third," Fletcher said, setting down the bottle and lowering his voice further, "and this is the most troublesome part—the review list includes the 'Black Widow defection incident.'"

The air in the office seemed to freeze for an instant. Lin Xiao could feel his heartbeat thudding heavily in his chest. He took a deep breath, filling his lungs with cold air before slowly exhaling.

"How far has it gone?" he asked, his voice still steady.

"Archive access has been opened," Fletcher said. "The review team can access all original records from that mission, including field reports, communications logs, witness testimony, even backup files that should have been destroyed."

Lin Xiao closed his eyes. He could imagine the scenes—agents in suits going through thick file folders in S.H.I.E.L.D.'s archives; encrypted database entries scrolling across computer screens; some sharp analyst noticing contradictions in the mission timeline or subtle gaps in the testimony.

In S.H.I.E.L.D.'s records from his previous life, Su Ying's defection had been classified as "a stress response following mission failure, possibly involving psychological trauma." But Lin Xiao knew the truth—it had been a carefully designed Hydra trap, meant to eliminate an elite agent who was too upright and too difficult to control. Now, that trap might be reopened.

"Does Fury know?" Lin Xiao asked.

"He should," Fletcher said. "But I'm not sure what his attitude is. Fury... you can never tell what he's thinking. He may genuinely want to clear out Hydra infiltration, or he may simply be testing the loyalty of internal personnel. Or both."

The image on the screen jolted as the car seemed to turn into an alley. The light dimmed, making Fletcher's face look even graver in the shadows.

"I need you to warn Su Ying," he said. "If the review team really discovers something, they may initiate a pursuit protocol. She's in Eastern Europe now, but S.H.I.E.L.D.'s reach is long, especially when it comes to 'traitors.'"

"Understood," Lin Xiao said.

"There's one more thing." Fletcher hesitated. "I heard there's an analyst named Sitwell on the review team. He's particularly interested in Hydra's history. Recently, he accessed a large number of Hydra files from World War II, including Dr. Zola's early research records."

Lin Xiao's pupils contracted slightly.

Jasper Sitwell. Lin Xiao remembered that name—in the original timeline, this seemingly mild-mannered senior S.H.I.E.L.D. agent was actually a deeply embedded Hydra operative. He was one of the key executors of Project Insight, until Captain America exposed his true identity.

Now, Sitwell was investigating Hydra's history. It sounded ironic, but Lin Xiao knew this could be an internal Hydra self-inspection procedure—using an "investigation" to erase organizational traces that might be exposed, or... to identify disobedient pieces on the board.

"Thank you for the intelligence," Lin Xiao said.

"Stay alert," Fletcher said at last, then cut the connection.

The screen went dark. Silence returned to the office. Lin Xiao sat in his chair, watching the sun rise higher outside. Sunlight filtered through the glass and cast bright patches across the floor. He could hear impacts coming from the training ground downstairs—Black Bear was likely leading the new members through combat drills—along with faint counting.

Everything looked so normal. Yet beneath the surface, dark currents had already begun to surge.

At three in the afternoon, Lin Xiao went to the training ground.

It was an enclosed space converted from an old warehouse, with soundproofing on the walls and thick training mats across the floor. The air smelled of sweat and rubber, mixed with the dull thuds of bodies striking sandbags.

Su Ying was in the center of the floor. She wore a black training suit, her hair tied into a neat ponytail, fine beads of sweat covering her forehead. Her opponents were three combat-simulation robots—equipment Artisan had recently modified, their shells covered in bionic material, moving faster than humans and attacking from trickier angles.

Lin Xiao stood at the edge of the floor without interrupting. He watched Su Ying slip sideways past the first robot's straight punch while kicking the joint connection of the second. A harsh screech of twisting metal rang out as that robot staggered backward. The third lunged from the side, its mechanical arm smashing toward her head with a rush of wind.

Su Ying did not dodge. She charged straight toward the arm, lowered herself into a sliding step at the last moment, and passed beneath the robot's armpit. At the same time, she drove a reverse elbow into the control panel on its back. Sparks burst out. The robot stiffened, then crashed to the floor.

The entire exchange took less than five seconds.

The other two robots adjusted their stances, but Su Ying had already created distance. She drew two rubber training daggers from her waist, spun them once in her hands, then lunged forward.

The next thirty seconds were a textbook demonstration of close-quarters combat. Lin Xiao watched every movement—precise, efficient, without a single unnecessary flourish. Her breathing remained even throughout, never faltering even during the most intense explosive bursts of movement. Sweat dripped from her chin, leaving dark marks on the training mat.

When the final robot had been dismantled into parts, only Su Ying's heavy breathing remained in the training ground. She stood in place, her chest rising and falling, sweat soaking the back of her training suit. Several new members at the edge of the floor stared in stunned silence, forgetting even to applaud.

Lin Xiao walked over. Su Ying turned, saw him, and smiled faintly. The smile was slight, but her eyes held the satisfaction of finishing an intense workout. She took the towel Lin Xiao offered and wiped the sweat from her face.

"Something wrong?" she asked, her voice slightly hoarse from exertion.

"Come to my office," Lin Xiao said.

Su Ying nodded and followed him out of the training ground. As they walked down the corridor, several resting members nodded to them in greeting. Lin Xiao could smell the heat coming off Su Ying's body and the salt of her sweat, along with the training ground's distinctive mixture of rubber and metal.

Once the office door closed, the world became quiet. Lin Xiao walked to the window and pulled down the blinds. The light was cut into narrow strips, casting alternating bands of brightness and shadow across the room. He turned to look at Su Ying.

She sat on the sofa, wiping sweat from her neck with the towel. Her training suit clung to her body, outlining her muscles. Her cheeks were flushed from exercise, and her gaze was bright and focused.

"S.H.I.E.L.D. has begun an internal review," Lin Xiao said directly.

Su Ying's hand paused for an instant. Then she continued, though more slowly. The towel folded and unfolded in her hands before folding again. Her gaze fell on the ceramic ashtray atop the coffee table—something Lin Xiao never used but always kept there, like a decoration.

"How extensive is the review?" she asked calmly.

"Every 'resolved' case from the past five years," Lin Xiao said. "Including your mission."

The room fell silent for several seconds. Wind drifted through the gaps in the blinds, accompanied by the rumble of trucks passing along the distant highway. The office clock ticked steadily, every second unusually clear.

Su Ying set down the towel. Her fingers lightly tapped against her knee, a habitual motion whenever she thought. Lin Xiao could see the small scars on the back of her hand—some old wounds, some left by recent training.

"And the files?" she asked.

"Full access," Lin Xiao said. "Including original records and backup files."

Su Ying closed her eyes. Her breathing became deep and slow, her chest rising and falling rhythmically. Lin Xiao knew she was remembering—remembering the night that had changed her life, the gunfire, the flames, and the sight of her comrades falling.

"There were three witnesses at the scene," Su Ying said when she opened her eyes, her voice carrying cold precision. "Two were embedded Hydra agents. Their testimony would paint me as an out-of-control killer. The third was a real S.H.I.E.L.D. agent, but he was injected with hallucinogens before the mission began. His memories were muddled, and his testimony was unreliable."

She paused. "I wrote the mission report, but it was altered before submission. Key timestamps were adjusted, and part of the communications log was deleted. I later tried to appeal, but all the evidence pointed to me being mentally unstable and prone to violence."

Lin Xiao walked over and sat in the chair opposite her. Light filtering through the blinds cast mottled shadows across his face. He could see the anger hidden deep in Su Ying's eyes—not a violent outburst, but a cold anger tempered by time.

"What if the review team finds contradictions?" he asked.

"They will open an investigation," Su Ying said. "First, they will try to contact me and demand that I cooperate with questioning. If they cannot reach me, or if I refuse to cooperate, they will classify me as a fugitive suspect and issue an internal warrant. Then... the pursuit protocol begins."

Her voice was calm, as if she were describing something unrelated to herself. But Lin Xiao could sense the tension beneath that calm—like a bowstring drawn to its limit, motionless on the surface yet bearing immense strain within.

"Fletcher mentioned a name," Lin Xiao said. "Sitwell. He's on the review team, and he is especially interested in Hydra's history."

Su Ying frowned. "Jasper Sitwell? The guy who is always smiling and likes collecting antique pocket watches?"

"You know him?"

"I've met him a few times," Su Ying said. "At annual meetings at headquarters. He came across as a mild bureaucrat who liked tea and spoke slowly. But once, I saw him reprimanding a junior agent, and his eyes changed completely."

She recalled, "It was in a corridor outside the archives. That agent lost a low-level classified document, and Sitwell called him aside. I happened to pass by and heard him say, 'At S.H.I.E.L.D., negligence is betrayal.' His voice was soft, but his tone... was terrifyingly cold."

Lin Xiao nodded. It fit Sitwell's true face—the Hydra operative concealed beneath a gentle exterior.

"If he is on the review team," Su Ying said, "then things are more complicated. He may really be investigating Hydra, or he may be taking the opportunity to eliminate threats. Or... both."

She rose and walked to the window. Through the gaps in the blinds, she could see the town streets. A few children kicked a football by the roadside, the bakery owner was wiping the display window, and a mailman cycled from house to house delivering letters. A peaceful afternoon, utterly detached from the world of her past.

"Do I need to leave?" Su Ying asked without turning around.

"No," Lin Xiao said.

She turned around. Lin Xiao rose as well and walked over to her. The distance between them was close enough for them to hear each other breathe. Light from the blinds cast a boundary of brightness and darkness between them, as though dividing the room into two worlds.

"You stay here," Lin Xiao said. "This is our base, our territory. However far S.H.I.E.L.D.'s reach extends, reaching Eastern Europe takes time, resources, and justification. Until they find conclusive evidence, you are safe."

"But what if they find it?" Su Ying asked.

"Then we make sure they do not," Lin Xiao said. His voice remained calm, but it held an unquestionable firmness.

"I've already had Nightingale begin erasing every digital trace that could reveal your location," Lin Xiao continued. "Your false identity, bank records, entry and exit records—every lead that can be traced will be overwritten or forged within twenty-four hours. At the same time, Grey Falcon will monitor all internal S.H.I.E.L.D. communications. The moment an order to pursue you is issued, we will know."

Su Ying was silent for several seconds. Then she nodded. "I trust you."

Four simple words, yet Lin Xiao could hear their weight. It was the trust of placing one's life in another's hands, the tacit understanding of walking side by side through darkness.

Children's laughter drifted in from outside. There was the dull thump of a football hitting a wall and mothers calling their children home for dinner. Those sounds passed through the glass and the gaps in the blinds, floating into the tense room and forming a strange contrast.

"There's one more thing," Su Ying said. "Grey Falcon contacted me this morning. He heard from an old S.H.I.E.L.D. contact that the internal investigation team has not only accessed my files, but... they may have already discovered some contradictions in the records."

Lin Xiao's heart sank. "What contradictions?"

"Not clear yet." Su Ying shook her head. "But that contact said that while cross-checking the mission timeline, the investigation team found several 'unexplainable gaps.' There are seventeen missing minutes in the communications logs, several key timestamps in the field report do not match, and... an agent who was supposed to have died in that mission was recently found alive, living under an assumed name in Brazil."

Information flashed rapidly through Lin Xiao's mind. Missing communications logs—Hydra may have deleted conversations that would expose the trap. Mismatched timestamps—perhaps to conceal the true sequence of operations. An agent presumed dead still alive—this might be the most fatal flaw. A living witness could overturn the entire official conclusion.

"What is that agent's name?" Lin Xiao asked.

"Marcus Lane," Su Ying said. "Codename Shepherd. He was the field commander for that mission. According to official records, he was struck in the head by a stray bullet during the firefight and died on the spot. His body was later transported back to the United States, and a funeral was held."

"But now he is in Brazil."

"Yes," Su Ying said. "Grey Falcon's contact said that while investigating a South American drug case, S.H.I.E.L.D. accidentally photographed a man resembling Lane. The picture was blurry, but facial-recognition software gave an 87% match. The review team has already sent people to verify it."

Lin Xiao walked to his desk and turned on the computer. He accessed S.H.I.E.L.D.'s public archives database—one Nightingale had cracked earlier. Its permissions were limited, but it contained some basic information. He entered "Marcus Lane," and the search results appeared quickly.

A brief profile, an ID photograph, and a cold line of text: "Killed in action on November 7, 2010, at an undisclosed location in Eastern Europe. Aged 42. Posthumously awarded the S.H.I.E.L.D. Medal of Valor."

The man in the photo had a square face, dark eyes, and the faintest hint of a smile at the corners of his mouth. His insignia identified him as a Level Eight agent, a mid-ranking commander.

"If he is alive," Lin Xiao said, "and willing to testify, then the entire official conclusion about your defection will collapse."

"But Hydra will not let him live to testify," Su Ying said coldly.

Lin Xiao looked up at her. Su Ying stood amid the light and shadow by the window, expressionless, yet her eyes held the clarity of someone who saw through everything.

"Hydra designed that trap, so they will certainly remove every piece of evidence that could overturn the case," she said. "There are only two possibilities for why Lane is still alive. First, he is Hydra, and he faked his death to escape. Second, he was lucky enough to evade the cleanup, but Hydra has been searching for him ever since."

She paused. "Either way, once S.H.I.E.L.D. finds him, Hydra will act. They will either silence him, or... make him say what they want him to say."

The room fell quiet. The wind outside seemed to grow stronger, and the blinds trembled lightly. Church bells rang in the distance, low and far-reaching, as if announcing the arrival of some moment.

Lin Xiao shut off the computer screen. The ID photograph vanished into darkness, leaving only his own blurry reflection in the screen.

"We need to prepare for both possibilities," he said. "First, find Lane before S.H.I.E.L.D. does. Second, prepare for S.H.I.E.L.D.'s pursuit."

Su Ying walked over to him. Her training suit had dried from her body heat, though the salty scent of sweat still lingered in the air. Her eyes seemed exceptionally bright in the dim light, like two pieces of obsidian immersed in ice water.

"What are you going to do?" she asked.

Lin Xiao looked at her, at the woman who had once died for him in another timeline, at the partner now standing beside him in the darkness.

"I'll have Wolf activate his network of contacts in South America," he said. "At the same time, Nightingale will try to track the S.H.I.E.L.D. investigation team sent to Brazil. We need to know their progress, their route, and their operational plan."

He paused. "As for you, reduce your outings from today onward. Training can continue, but do not leave the base perimeter. All contact with the outside world goes through encrypted channels. If you must appear in public, use a disguise and a false identity."

Su Ying nodded. "Understood."

Outside, the sky began to darken. The last glow of sunset broke through the clouds, dyeing the sky orange-red. The light filtering through the blinds turned warm gold, casting long shadows across the walls.

Another day was coming to an end. But the storm had only just begun.
