Chapter 4: Echoes in the Quantum Ripples

The dome of the holographic laboratory still held the residual projection of a purple nebula. Lin Shen’s fingertips danced across the air-keyboard, casting fragmented light spots onto his lenses. The image of the light-cocoon planet, displayed by the Dream-Weaver race three days ago, still burned on his retinas. He could hear his own heartbeat mingling with the hum of the air conditioning, sounding like some primitive Morse code.

“Professor Lin, the information packet is ready.” The voice of his assistant, Xiao Chen, came from behind. “Earth’s atmospheric spectrum, the DNA double helix model, and the sound file of ‘Moonlit Night on the Spring River’ that you specifically requested.”

Lin Shen stopped typing and turned, his lab coat sleeve brushing against the quantum storage unit on the console. The surface of the unit shimmered with a ghostly blue light—it contained the most tender slices of human civilization. He had insisted on including the ancient poem’s audio because mathematical formulas were too cold, and emotion, perhaps, was the only universal language of the universe.

“Transmit,” he said, his Adam’s apple bobbing.

At 14:23 on May 17, 2045, the deep-space antenna array directed toward Alpha Centauri lit up in unison. The information packet, carrying the warmth of Earth, surged toward the aliens at the speed of light, like the first pebble cast into a deep cosmic pool.

Three days later, in the small hours of the morning, the silence of the night in the control room of the Guizhou FAST telescope was torn apart by an alarm.

The sound of Xia Qing’s tactical boots grinding against the metal steps was sharper than the alarm itself. She stood before the command console, her eyes sweeping over the green waveforms leaping across the screen. Her finger tapped heavily on the label marked “Anomaly Band.” “This is not an electromagnetic pulse.”

Beads of cold sweat broke out on the operator’s forehead. “According to the spectral analysis, it is… a secondary fluctuation superimposed on the original signal. The frequency is 1.3 Hz, consistent with the initial signal, but the amplitude exhibits characteristics of quantum entanglement.”

When Lin Shen rushed into the control room, his lenses were still smudged with uncleaned coffee stains. His gaze, fixed on the screen, suddenly turned incandescent—the trajectory of the fluctuations looked uncannily like the outlines of the Dream-Weaver light-cocoon structures.

“Activate the brain-computer interface.” He tore off his lab coat and tossed it onto the back of his chair. “They are responding.”

Xia Qing’s hand pressed onto his shoulder. Her palm, calloused from years of gripping tactical terminals, felt as cold as deep space. “Professor Lin, this could be an energy probe. Do you know the startup spectrum of an antimatter engine?”

Lin Shen turned to look at her, his eyes shining brilliantly behind his lenses. “But they gave us mathematical formulas and civilization imagery first. If this is a probe, then our information packet was the bait—but what if it isn’t?”

Xia Qing’s fingers tightened slightly before finally relaxing. She took a half-step back, her tactical terminal unfolding a holographic screen in her palm to synchronize all monitoring data.

As the hatch of the brain-computer pod closed, Lin Shen heard his own breathing amplified in the enclosed space. The moment the neural interface touched the back of his neck, an electric current surged up his spine into his brain, feeling like frigid stardust wandering between his neural synapses.

In the darkness, a warm tremor washed over his sea of consciousness. It was not sound, nor image, but emotion—like the crackle of burning wood in a hearth on a winter night, like the first ray of spring sunlight sweeping across an icy surface, like countless star trails slowly rotating in his mind, each trajectory glowing with a gentle silver light.

His fingers lifted uncontrollably, tracing arcs in the void. They were the arcs of the Dream-Weaver light-cocoon architecture, the arcs of the DNA double helix in the information packet, and the arcs of the “Who by the river first saw the moon?” from *Moonlit Night on the Spring River*.

“Resonance wave… carrying emotional frequency.” Lin Shen’s voice emerged from the brain-computer pod with a strange tremor. “They are saying ‘I hear you,’ using emotion.”

Xia Qing’s tactical screen suddenly erupted in blinding red light. Her pupils constricted—the decay curve of antimatter particles was climbing at a speed visible to the naked eye, like a viper baring its fangs.

“Stop the connection!” she roared, grabbing the communicator. “Lin Shen, terminate the interface immediately!”

The alarm in the brain-computer pod sounded at the same time. Lin Shen’s consciousness was violently dragged back to reality, his temples throbbing with pain. As he removed the interface, the skin on the back of his neck was an unnatural red, as if kissed by something gentle yet scorching.

“Antimatter particle concentration is 0.03 nanograms per cubic centimeter.” Xia Qing shoved the tactical screen in front of him, the data still jumping. “This is a secondary byproduct of Dyson membrane absorption of stellar energy. The mark of a Star Hunter.”

Lin Shen’s fingers unconsciously rubbed the quantum storage unit in his lab coat pocket—the one containing the sound file of *Moonlit Night on the Spring River*, which was now growing slightly warm against his heartbeat. “But the structure of the resonance wave is completely different from the Star Hunters,” he said. “The level of quantum entanglement is higher; it is more like… emotional resonance.”

“Emotion?” Xia Qing sneered, the cold light of the tactical screen cutting across her brow. “During the Mars Defense War, asteroid swarms also used gravitational waves to ‘gently’ say ‘I am about to crash into you.’ Professor, you believe too much in the goodness of humanity, but the universe is not named ‘Goodness.’”

Rapid footsteps suddenly echoed outside the control room. Oleg Petrov’s silver hair gleamed with a cold white light in the corridor. He clutched a freshly printed report in his hand, the title on the cover, “Feasibility of Reverse Engineering Dream-Weaver Technology,” stinging the eyes.

“Both of you,” he said, his voice carrying the polished smoothness typical of a politician. “I just received a classified report from the Lunar Base—they used a neutrino telescope to capture the source point of the resonance waves.” He flipped open the report and pointed to the star map on the last page. “It is not Alpha Centauri. It is… a companion star to Alpha Centauri B. A red dwarf on the verge of extinction.”

Lin Shen’s breath hitched. A red dwarf’s lifespan could last hundreds of billions of years, but being on the verge of extinction meant…

“The Dream-Weavers are extracting its energy.” Oleg’s finger tapped on the star map. “The quantum resonance network requires stellar energy; their home planet may have already been depleted. And our information packet,” he looked up at Lin Shen, “may have shown them a new energy source.”

Xia Qing’s tactical screen suddenly vibrated. She glanced down at the message, her face turning as cold as deep space. “Mars base reports that the resonance waves are spreading to the edge of the solar system. The vanguard has reached the asteroid belt.”

The control room fell into a dead silence. Only the quantum storage unit in Lin Shen’s pocket remained hot—the most tender slice of human civilization, now feeling like a piece of burning iron.

“Prepare the deep-space probe.” Xia Qing’s voice sounded like frozen metal. “I want to know what these waves are actually probing.”

“And initiate the reverse engineering,” Oleg added, his gaze sweeping over Lin Shen. “The laboratory at the Lunar Base is ready. We will use the quantum entanglement characteristics of the resonance waves to crack their communication technology.”

Lin Shen looked up sharply. “No! The Civilization Contact Protocol states that if a lower-level civilization attempts to reverse-engineer advanced technology, it will trigger an exclusion protocol—”

“That is just speculation!” Oleg’s voice rose sharply. “And the Dream-Weavers are likely using our information to locate the solar system! Professor, do you want to repeat the Earth’s ecological crisis? Back then, we waited ten years to act, and three hundred million people died!”

Lin Shen’s fingers gripped the hem of his lab coat. Childhood memories suddenly surged back: a gray-yellow sky, cracked earth, his mother holding him in a refugee camp queue to collect water, with half a withered leaf floating in their canister. He had sworn then that he would never let civilization be trapped in the mire of survival.

“I am going to the asteroid belt,” he said suddenly. Everyone turned their eyes to him. “I will use the *Ark* probe module to make personal contact with the vanguard of the resonance waves.”

Xia Qing’s pupils contracted. “Are you crazy? The density of meteorites in the asteroid belt is twenty times that of Earth’s orbit, and besides—”

“This is the only way to confirm their intentions.” Lin Shen took off his silver-rimmed glasses and wiped them with his sleeve, his eyes shining with a scorching intensity. “If they are benevolent, we need emotional resonance; if they are malicious… at least I can be the first to know.”

Oleg suddenly laughed. He patted Lin Shen on the shoulder, the force heavy as lead. “Professor, you are always so idealistic. But I admire you—the reverse engineering at the Lunar Base will need your data support.”

Xia Qing stared at Lin Shen, her gaze like that of someone watching a child walk into a minefield. She finally just turned around, the sound of her tactical boots grinding against the metal steps heavier than before. “I will have the *Ark* prepared. But if there is any anomaly, I will activate the defense protocol immediately.”

The lights in the control room dimmed one by one behind her, leaving only the screen in front of Lin Shen lit. The dancing trajectory of the resonance waves looked like some unfinished conversation. He pulled out the quantum storage unit and pressed it gently against the screen, as if by doing so, he could transmit the tenderness of *Moonlit Night on the Spring River* to a civilization three light-years away that spoke in emotions.

Outside the window, the dawn was breaking over the Guizhou sky. And at the edge of the solar system, the vanguard of the resonance waves had touched the first asteroid, like a hand tentatively reaching out to touch something new, carrying the peace of orbiting star trails, and also carrying, unknown even to its masters, the scorching pain of survival.
