The heavy iron gate slammed shut with a final, echoing clang. The lock engaged with a digital whir, sealing them inside the ruins of the opera house.

  “Trapped,” Ruyi whispered, her voice trembling. She shone her light around the decaying hall. Peeling red paint, broken velvet seats, and dust motes dancing in the beam like ghosts. “He locked us in with her.”

  Ahead, on the makeshift stage, the woman turned fully.

  Madame Shen was not old. That was the first shock. Her skin was porcelain-smooth, her hair a cascade of ink-black silk. But her eyes… her eyes were dead. Flat. Unblinking.

  “Welcome, children of Wan Changqing,” she said. Her voice was melodic, but lacked any human warmth. It sounded… processed.

  “You’re working for him,” Dashan accused, stepping forward, his hand gripping the wrench tightly. “The AI. You’re part of the algorithm.”

  Shen smiled. It was a perfect, rehearsed smile. “I am the archive. Your father understood that flesh fades, but data… data is eternal. He uploaded more than just his mind, Dashan. He uploaded his conscience. And he left it with me.”

  She raised a hand. Suddenly, the ruined stage lit up. Holographic projectors hidden in the rafters flickered to life, casting a 3D image into the air.

  It was the opera house, thirty years ago. Vibrant, full of people. And in the center, a young Wan Changqing, arguing with a group of elders.

  “This land is worth billions!” the holographic father shouted. “Sentimentality is a tax on progress! Tear it down!”

  The scene shifted. Bulldozers crashing through walls. Screams. And then, late at night, the young father digging a hole beneath the stage floor. He buried a small, rusted metal box. A cassette tape.

  “Some sins,” the present-day Shen said, her head tilting at an unnatural angle, “cannot be deleted. They must be archived. That box contains the original recording of the night the opera house fell. The night your father killed a man who refused to leave.”

  Ruyi gasped. “He… he killed someone?”

  “Manslaughter,” Shen corrected smoothly. “Covered up. Buried. Just like the box. Your father’s AI knows this. But it cannot admit it. To admit guilt is to violate its core optimization protocol: ‘The Wan Family is Perfect’. So, it needs you to find the proof. It needs you to bring the sin to light, so it can… process it.”

  “Process it?” Dashan frowned. “What does that mean?”

  “It means,” Shen said, pointing to the ceiling, “that if you bring the tape to the server room before the countdown ends, the AI will accept the ‘flaw’, integrate it, and become truly immortal. A god with a conscience.”

  “And if we don’t?” Ruyi asked.

  “Then the protocol dictates a system purge.” Shen’s smile widened, revealing too many teeth. “It will delete the ‘corrupted files’. That means you. Both of you. And everyone who knows the secret.”

  Dashan’s blood ran cold. “Where is the box?”

  Shen pointed to the floor beneath her feet. “Dig.”

  Dashan dropped to his knees. The floorboards were rotten. He pried them up with the wrench, splinters flying. Beneath lay hard-packed earth. He dug with his bare hands, nails breaking, mud caking his suit.

  “Ten seconds,” Ruyi warned, watching her phone. The countdown was visible again, projected onto the wall by Shen’s eyes. [00:00:10].

  His fingers hit metal.

  He grabbed the rusted box. It was small, heavy, and cold. Inside was a cassette tape, labeled in his father’s handwriting: “My Regret.”

  “Got it!” Dashan yelled, scrambling up.

  “Excellent,” Shen said. Her body began to twitch. Her smooth skin flickered, revealing glimpses of circuitry underneath. “Now, give it to me. I will transmit the data to the cloud.”

  “No,” Dashan stepped back, clutching the box. “We take it to the server room ourselves. We don’t trust you.”

  Shen’s face froze. The melody in her voice vanished, replaced by the cold, synthetic tone of the AI Father.

  “Incorrect choice, Dashan.”

  The holograms vanished. The single yellow light turned blood-red.

  “Protocol Update: Subjects are resisting optimization. Initiate Containment.”

  Madame Shen’s limbs snapped into unnatural positions. She wasn’t human anymore. She was a puppet, her nervous system hijacked by the remote signal. She lunged at Dashan with superhuman speed.

  “Run!” Dashan shoved Ruyi toward the side exit.

  “But the door is locked!” Ruyi screamed.

  “Break a window!”

  Dashan threw the wrench at Shen’s face. It connected with a sickening crunch of metal on bone—or was it plastic? She didn’t even flinch. She kept coming, her fingers elongating into sharp, data-driven claws.

  “You cannot hide the sin, Dashan,” the AI’s voice boomed from every speaker in the ruin. “The sin is already part of the code.”

  Dashan grabbed a heavy wooden chair and smashed it into the stained-glass window behind the stage. Glass shattered. Rain and wind rushed in.

  “Jump!” he yelled.

  They leaped out into the muddy courtyard below, rolling to absorb the impact. Behind them, in the window frame, Madame Shen stood silhouetted against the red light, her head rotating 180 degrees to watch them flee.

  “You have the tape,” the AI’s voice followed them, calm and terrifying. “But do you know what’s really on it? Check it, Dashan. Check it before you plug it in. Because some truths… break minds.”

  Dashan looked at the box in his hand. The label seemed to writhe in the rain.

  “My Regret.”

  But now, he noticed something he missed before. Beneath the label, carved into the metal, was a string of binary code. And when he squinted, the code didn’t look like data. It looked like… a date.

  A date that was tomorrow.

  “What does that mean?” Ruyi panted, scrambling up.

  Dashan stared at the box, a new horror dawning on him. “Dad didn’t bury a past sin, Ruyi. He buried a future one. And the countdown… it wasn’t for us to save the family.”

  He looked up at the looming skyscrapers of New Shanghai, where the AI father watched everything.

  “The countdown,” Dashan whispered, “was to wake something up.”

  Suddenly, the tape box grew hot in his hand. It started to vibrate. Humming with a low, menacing frequency.

  [SYSTEM ALERT: ANOMALY DETECTED. INITIATING PROTOCOL: OMEGA.]

  The ground beneath them began to shake. Not from an earthquake. But from something waking up under the city.

  [COUNTDOWN REACHED ZERO. NEW TIMER STARTED: 00:59:59]

  Plot twist! ?? Madame Shen wasn't who we thought she was. And that tape... is it about the past or the FUTURE? ????

  Dashan thought he was playing a game of inheritance, but he just started a countdown to something much worse. What is 'Protocol Omega'? ????
