4. 宴会请柬

The three days between Thursday morning and Saturday evening passed in a strange, suspended stillness, like the air before a thunderstorm. The compound went about its routines—the vegetable vendor sold her bok choy, the chess players clicked their wooden pieces, the children ran to school with their backpacks bouncing—but every interaction was laced with a new, electric wariness. Neighbors who had once exchanged pleasantries now avoided eye contact. Conversations in the elevator died the moment a third person entered. The forum remained active, but the posts had become cryptic, allusive, as if the participants were speaking in code to avoid the attention of some unseen arbiter.

Chen Li had not shared the doctored image of Old Liu. She had not shared anything since Wednesday morning, when she had received the anonymous message with the timestamp manipulation. She had spent Thursday and Friday in a state of quiet observation, scrolling through every post, every reply, every private message that had been forwarded to her by her network of informants. She had compiled a list of usernames, timestamps, and content patterns, and she had begun to see a shape emerging—a silhouette behind the fog of digital noise. The account "SilentWatcher" had been active for over three years, but its activity had spiked dramatically in the past six months, coinciding with a series of minor community disputes: a parking space conflict, a complaint about noisy renovations, a dispute over shared hallway maintenance. In each case, SilentWatcher had posted neutral-sounding observations that had subtly inflamed the conflict, nudging neighbors toward open hostility. The account had never taken sides openly. It had never issued a direct threat. It had simply been there, like a chess player who never moved a piece but always adjusted the board.

Chen Li had also noticed another pattern: SilentWatcher's posts were always made during the same time window—between 2 AM and 4 AM, when the compound was asleep. That suggested someone with a nocturnal schedule, or someone who deliberately chose the dead of night to avoid detection. She had cross-referenced the building's residents with their known sleeping habits, but the list was too broad. What she needed was a direct connection—a piece of evidence that linked SilentWatcher to a physical person in the compound.

On Friday afternoon, she received a private message from an unknown number. The message contained a single link—a Google Drive folder with a timestamped log of every SilentWatcher post, cross-referenced with IP address fragments that had been captured by the forum's backend. The fragments were incomplete, but they pointed to a single ISP provider—the same one used by Building 7's entire block. More tellingly, one of the log entries showed that SilentWatcher had accessed the forum from a device that had also accessed the hospital's patient portal—the same portal that Wang Xu used to check his mother's medical records. The implication was unmistakable: SilentWatcher was someone in Wang Xu's immediate circle, someone who knew about the medical case intimately.

Chen Li sat back from her phone, her heart beating faster than it had in years. She considered the possibilities. It could be Wang Xu himself, using a burner account to deflect suspicion from his own public posts. It could be Lin Wei, acting out of some hidden grievance against her husband. It could be a relative—a brother, a cousin—who had access to the family's medical information. But the timing of the posts—always between 2 and 4 AM—did not fit Wang Xu's schedule, since he was known to sleep early and wake early for his hospital visits. Lin Wei, on the other hand, had admitted to being a night wanderer. She had gone to the bridge at midnight. She could have been the one.

Chen Li did not confront anyone. She saved the evidence, locked her phone, and went to prepare dinner for her children. But her mind was already racing ahead to Saturday, to the reconciliation dinner that Wang Xu had announced through a group message earlier that day. The message had been carefully worded: "Dear neighbors, I invite you to my garden this Saturday at 7 PM for a simple meal. I want to apologize for my role in the recent tragedy, and I want to open a dialogue about how we can heal as a community. Please come. Bring only yourselves and your willingness to listen." The replies had been mixed—some enthusiastic, some skeptical, some outright hostile—but enough people had confirmed their attendance to fill the garden's ten wooden tables.

Chen Li had confirmed her attendance. She had also, in a moment of impulse, texted A-Jie's mother—whose name she had learned was Liao Fen—to invite her personally. Liao Fen had not replied. But Chen Li had seen her through the window of Unit 301, moving like a ghost behind the curtains, and she knew that Liao Fen would come. She had to come. She was the reason the dinner existed at all.

Across the building, in Unit 301, Liao Fen was doing something she had not done in four days: she was cooking. She had found her son's note, the one that said "It's not who you think," and she had spent the past two days tracing the threads backward, following the digital breadcrumbs that her son had left behind. She had accessed his phone, his chat history, his private messages, and she had found something that made her blood run cold: a conversation between A-Jie and a user named "SilentWatcher" that had taken place on the night of the IOU screenshot, hours before Wang Xu had posted anything. SilentWatcher had messaged A-Jie first, with a screenshot of the IOU and a message that read: "Your debt is already public. Wang Xu posted it. But don't worry—I have a plan to help you. Just send me your phone number and I'll arrange a loan." A-Jie, desperate and naive, had sent his number. SilentWatcher had then forwarded that number to another user, who had sent the anonymous threats—the "We know where you live" messages. SilentWatcher had played both sides: the helper and the tormentor, the one who offered a lifeline and the one who cut the rope.

Liao Fen had saved the conversation. She had printed it, folded it, and tucked it into her jacket pocket. She had also printed the note her son had left, and the photo of the bridge, and the first screenshot of the IOU—the one that SilentWatcher had sent to A-Jie before Wang Xu had even opened his phone. She was building a case, piece by piece, and she intended to present it at the dinner. Not to accuse Wang Xu—she no longer believed he was the architect. He was a pawn, a convenient face, a tool that SilentWatcher had wielded with surgical precision. The real architect was still out there, anonymous and untouchable, and Liao Fen was going to force them into the light.

On Saturday morning, the compound woke to a bright, clear sky—the kind of sky that seemed to mock the darkness that had settled over the community. Wang Xu and Lin Wei spent the entire day preparing the garden: arranging tables, hanging fairy lights, setting out porcelain plates that had been inherited from Wang Xu's mother. They had bought fresh flowers—white lilies and yellow chrysanthemums—and placed them in vases at the center of each table. They had prepared a feast: cold noodle salad, braised pork belly, stir-fried greens, steamed fish, and a large pot of lotus root soup. Lin Wei had baked a cake—a vanilla sponge with buttercream frosting—that sat on the kitchen counter, covered with a glass dome.

At 4 PM, Wang Xu received a call from the hospital. His mother's condition had improved; she had been moved from the ICU to a regular ward. The news was a relief, but it also brought a wave of guilt—he had not visited her in two days, too consumed by the dinner preparations and the ongoing chaos. He promised to come tomorrow, hung up, and returned to the garden, where Lin Wei was arranging the chairs.

At 5:30 PM, Old Liu arrived at the gate for his evening shift. He had not slept well in days. The anonymous messages had stopped—the sender had gone silent since Wednesday—but the rumors had not. Every time he walked through the compound, he felt eyes on him, heard whispers that ceased when he turned around. He had considered quitting, disappearing, starting over again somewhere else. But the message from A-Jie's mother—she had knocked on his booth door that morning, handed him a folded printout, and said simply, "Read this. Come to the dinner. I need you there."—had changed his mind. He had read the printout, and he had seen the evidence of SilentWatcher's manipulation. He had realized, with a sickening clarity, that he was not the only one being targeted. The same invisible hand that had exposed his past had orchestrated the entire cascade of events, turning neighbor against neighbor like a puppeteer pulling strings.

At 6:30 PM, Chen Li left her apartment with her husband and two children. She had dressed in a simple navy dress, her hair pinned back, her phone in her pocket. She had instructed her children to be polite, to eat quietly, and to say nothing about the forum. They had obeyed, their young faces solemn with the weight of adult tensions. As they walked through the building's lobby, they passed Lin Wei, who was carrying a platter of dumplings to the garden. Chen Li nodded, and Lin Wei nodded back—a small, fragile gesture that spoke of a tentative ceasefire.

At 6:55 PM, the garden was nearly full. Ten tables, each seating six, were arranged in a loose semicircle around a central fountain that had been dry for years. The fairy lights cast a warm, amber glow over the faces of the attendees—thirty-seven adults and eleven children, representing almost every family in Building 7. Wang Xu stood at the front, near the fountain, holding a glass of tea. He looked nervous, his tie slightly askew, his forehead beaded with sweat despite the evening cool.

At 7:00 PM, he raised his glass and called for attention. The chatter subsided slowly, reluctantly, like water draining from a clogged sink. He cleared his throat and began to speak.

"Neighbors, friends—I invited you here tonight not to make excuses, but to say I am sorry. I am sorry for the way I handled the debt with young A-Jie. I am sorry for posting his IOU without considering the consequences. I am sorry that my anger—my justified anger, I thought—turned into something that hurt our community. I cannot bring him back. I cannot undo what happened. But I can stand here and tell you that I was wrong."

He paused, his voice cracking slightly. Lin Wei stepped forward and placed a hand on his shoulder. The gesture was meant to be supportive, but several neighbors exchanged glances—some cynical, some sympathetic, some calculating.

"I do not know who sent the anonymous threats," Wang Xu continued. "I do not know who doctored the images. I do not know who started the rumors. But I want us to stop looking for scapegoats and start looking at ourselves. We all posted, we all shared, we all judged. We all held the magnifying glass. I am not blameless, and neither is anyone here."

A murmur rippled through the crowd. Someone shouted, "What about Old Liu?" Another voice called out, "What about your wife leaving at midnight?" Wang Xu held up his hand, and the murmur subsided.

"I will answer those questions," he said. "But first, I want to ask Liao Fen—A-Jie's mother—to come forward. She has something she wants to share with all of us."

The crowd turned toward the entrance of the garden. Liao Fen was standing there, her face pale, her eyes red, but her posture was straight—straighter than it had been at her son's funeral. She was wearing a plain black jacket, and her right hand was in her pocket, gripping the folded printouts. She walked slowly, deliberately, to the center of the garden, and she did not look at Wang Xu. She looked at the crowd, at the faces she had known for years, at the neighbors who had watched her son leave and said nothing.

She began to speak, her voice low and steady, like a bell tolling in the distance. "I have spent three days reading my son's phone. I have read every message he received, from everyone who wrote to him. And I have found something that I want all of you to see."

She pulled out the printouts, unfolded them, and held them up. The fairy lights caught the paper, illuminating the printed text. "This is a conversation between my son and a user named SilentWatcher. It took place before anyone else posted his IOU. SilentWatcher sent him a screenshot of the debt, told him it was already public, and then asked for his phone number—to 'help' him. And then, minutes later, my son started receiving threats from a number that SilentWatcher had forwarded his number to. SilentWatcher created the fire and then pretended to offer a bucket of water."

Gasps rippled through the crowd. Chen Li's heart raced. She had seen the same evidence, but she had not known that Liao Fen had found it too. She stood up from her seat and said, "I have similar evidence. SilentWatcher's IP fragments match a device that accessed the hospital portal—Wang Xu's mother's records. SilentWatcher is not a stranger. SilentWatcher is someone in this garden."

The crowd erupted into chaos. People turned to look at one another, suspicion flashing across every face. Wang Xu stepped forward, his hands raised. "I did not do this. I swear to you, I did not—"

"I know you didn't," Liao Fen said, cutting him off. "Because the conversation shows that SilentWatcher told my son that Wang Xu had already posted the IOU—before Wang Xu had actually posted it. SilentWatcher was lying to my son, manipulating him, driving him to despair. And the only way SilentWatcher could have known about the IOU before Wang Xu posted it was if they had access to Wang Xu's phone, his notebook, or his conversation with my son at the hospital."

The crowd fell silent. Every eye turned to Lin Wei, who was standing beside Wang Xu, her face drained of color. She looked at her husband, then at Liao Fen, then at the crowd, and she opened her mouth as if to speak. But no words came out.

Then, from the back of the garden, a voice cut through the silence. It was Old Liu, standing near the gate, his face grim and tired. "It's not her," he said. "I checked the logs too. The device that accessed the hospital portal was not Lin Wei's phone. It was the hospital's own public kiosk—anyone could have used it. But there's one person who had access to that kiosk and to Wang Xu's notebook at the same time. One person who followed Wang Xu to the hospital, who saw him write the IOU, who watched him post the screenshot, and who then created SilentWatcher to amplify everything."

He pointed a shaking finger toward a woman sitting at the third table—a woman with a sharp jaw, rimless glasses, and a navy polo shirt. It was Wang Xu's own sister, Wang Jing, who had come from her home in the southern district to visit her mother two days after the accident. She had been staying at Wang Xu's apartment since then, ostensibly to help with their mother's care. She had been the one who had access to Wang Xu's notebook when he left it on the living room table. She had been the one who had a grudge against the community—because years ago, she had been a victim of a similar online shaming campaign after a minor car accident, and she had never recovered.

Wang Jing's face hardened. She did not deny it. She did not flee. She stood up slowly, brushed a crumb from her polo shirt, and said, in a voice as cold as a scalpel, "You're all hypocrites. You crucified that boy for a debt, just like you crucified me for a dented bumper. I didn't kill him. I just showed him the truth—that the world is full of people like you, who judge without mercy, who click and share and move on. I gave him a mirror. He chose to break it."

The crowd recoiled. Wang Xu stared at his sister, his mouth open, his mind racing to reconcile the woman he had known all his life with the cold, calculating figure standing before him. He took a step toward her, but Lin Wei held him back. Liao Fen looked at Wang Jing, her eyes filled with a grief so deep it had curdled into rage. She took a step forward, her hand still gripping the printouts, and she said, "You gave him a mirror? You gave him poison. You sent him threats. You made him believe there was no way out. You are not a witness. You are not a victim. You are a murderer."

Wang Jing's lips curled into a thin, bitter smile. "Then arrest me," she said. "But first, let me ask you something, Liao Fen. When your son came home that night, when he looked at his phone, when he saw the first message—did you ask him what was wrong? Did you hold him? Did you tell him you loved him? No. You were at work. You were selling instant noodles. You didn't even know he was dying until he was already dead. So don't you dare point your finger at me."

The words hit Liao Fen like a physical blow. She staggered back, her face crumpling, the printouts falling from her hand. Chen Li rushed to catch her, but she was too late—Liao Fen collapsed onto the grass, sobbing, her body wracked with the convulsions of a grief that had finally found its outlet.

The crowd was frozen, paralyzed by the spectacle. Some turned away, ashamed. Others stared at Wang Jing, their faces hardening with a new, dangerous anger. Wang Xu grabbed his sister's arm and whispered, "Get out. Now. Leave this place and never come back." But Wang Jing did not move. She looked at the crowd, at the faces of the neighbors she had hated for years, and she said, "I'm not going anywhere. I'm going to watch you all destroy each other. Just like I planned."

The fairy lights flickered. The cake under its glass dome sat untouched. And in that moment, a child—Chen Li's youngest daughter—pointed at the cake and said, "Mommy, why is the frosting turning green?"

The chapter ends with the crowd turning toward the cake, where a faint, unnatural green hue was spreading across the buttercream, like a bruise rising on pale skin. Lin Wei let out a choked scream. Wang Xu rushed toward the cake, but Old Liu grabbed his arm and said, "Don't touch it. Call the police. Someone has been planning more than just exposure. This—this is the final cut."

And in the chaos, Wang Jing slipped away, not toward the gate, but toward the building's interior, her phone already in her hand, her finger hovering over a message that read: "Phase two begins now. The garden is only the appetizer." No one saw her leave. No one noticed that the cake's glass dome had been moved, replaced, and that the knife beside it—a long, serrated blade—was now missing from the serving table. The dinner had become a crime scene, and the real horror had only just begun.
