Chapter 169: Three Thousand Cradles

Inside the submarine cabin, only the low hum of the life‑support system could be heard. The two buttons on the holographic console resembled a pair of eyes—one burning, one icy—staring at the six tiny lives.

"Oxygen countdown: 19 minutes 47 seconds." Kaiwen's voice came through the delayed transmission, crackling with electric hiss, "How long can the ground defenses hold?"

The scene cuts to outside the temporary school, where a gray‑white tide is blocked by a seven‑colored light curtain. Thirty‑seven blank bodies hold hands in a circle, their bodies rapidly transforming—body 007's sphere sprouts vein‑like networks, body 008's arms grow scale‑like armor, body 009's legs extend into root‑like structures.

"We are learning the frequency of 'sacrifice.'" Body 007's voice is almost childlike, yet still carries a mechanical timbre, "Efficiency calculations show we can sustain the barrier for up to seventy‑two hours. But the learning progress indicates that for each hour we maintain it, our emotional module grows by 3.7%… potentially triggering unknown evolution."

Lin Shouzhuo, standing beside the organ, flipped to the last page of Ai O's notebook, his fingers trembling: "Found it… the device isn't a weapon; it's a 'hospital.' Three thousand years ago, when the Seran civilization began formatting emotions, Ai O and three hundred tuners stole this device and used it to preserve the 'civilization genes' of three thousand civilizations on the brink of homogenization."

He looked up, tears streaming, "But they lacked energy to keep it running forever. So… they used their own consciousness as power, sleeping within the device. At the same time, the device absorbs surrounding 'details' as supplemental energy—that's the source of the homogenization wave."

"It doesn't intend to destroy us," Su Yu said softly, "It's starving. To maintain the 'vital signs' of three thousand civilizations, it must constantly consume 'details.'"

Lao Zhao suddenly sat down, pulled the cracked photo frame from his inner pocket. He stared at the picture of his five‑year‑old son and his young wife, his fingers gently tracing the glass's fissures.

"When my wife died," he began, his voice calm, "she told me: 'Lao Zhao, you must live to see Xiao Feng marry, to see a grandson born, to see this world get better.'"

He paused, "She didn't say: 'You must live to see three thousand unfamiliar worlds improve.'"

Li Xiaofeng's voice came through the ground transmission, trembling with sobs, "Dad…"

"But Chen Mo said," Lao Zhao tucked the frame away, "He said a seed sprouts not to become the tallest tree, but to prove this soil can still grow something."

He looked at the holographic console, "If we shut it down, those three thousand civilizations will truly die. If we don't shut it… we die, and how long can the people on the surface hold out? Three days? Five days? Then they'll become parts too."

The cabin fell silent.

Only the ticking of the oxygen countdown remained: 17 minutes 03 seconds.

Han Qing's rainbow conduit flickered violently. He closed his eyes, fine beads of sweat seeping from his forehead— a physiological reaction that a Seran body shouldn't have.

"I received… a signal from inside the device," he said hoarsely, "It's the collective consciousness of three hundred Seran tuners. They're asking… who we are."

Su Yu placed her hand on his shoulder, and through the rainbow conduit connection, she "saw":

A vast, silvery consciousness space. Three hundred Seran tuners formed a circle, each holding an instrument—not a Seran technological artifact, but an ancient instrument from each civilization three thousand years ago: Earth's violin, a bone flute from some planet, a skin drum from another civilization…

They were playing, using their remaining conscious energy to keep the "song of civilization" of three thousand cultures unbroken.

Between them floated three thousand tiny light points—each a "gene bank" of a civilization: art, language, philosophy, emotional patterns… everything the Seran homeworld deemed "redundant" and deleted.

The performance has continued for three thousand years. The consciousness of the three hundred tuners is slowly dissipating, like a candle burning out.

Han Qing opened his eyes, "They… are about to collapse. If we shut the device, they'll be freed and the three thousand civilization genes will disperse. If we keep the device running… we must supply new 'detail energy.' Either from us, or from…"

He looked out the porthole at the fading deep sea, "All the 'details' of Earth."

Su Yu stepped before the holographic console. She didn't look at the buttons; instead she focused on one of the three thousand light points—its frequency resonated faintly with one of the seventeen crystal cores inside the organ.

It was Zhao Haisheng. The East Sea Fleet captain whose last preserved memory was the warmth of his daughter's small hand.

His memory frequency matched, almost exactly, the "fatherly love" frequency of a civilization stored in the device from a distant star system.

"Ai O left this device," Su Yu whispered, "not to make us choose who lives or dies, but to let us… find a third way."

She turned to Han Qing, "Your rainbow conduit can link the Seran system with human emotion. Can you… converse with those three hundred tuners?"

Han Qing nodded, his expression grave, "It's possible. But they're already too weak. Any dialogue will accelerate their dissipation."

"Then tell them," Su Yu clenched her fist, "it's been three thousand years; it's time for a shift. We… Earth civilization, request to succeed them."

Lao Zhao snapped his head up, "What?"

"With the organ," Su Yu's speech quickened, "using all our Emotional Frequencies, the 'sacrifice' the thirty‑seven blank bodies are learning, the light Chen Mo left, the love taught by geometry—we'll create a temporary 'civilization cradle.' Transfer the three thousand civilization genes into our plant network for now."

Kaiwen's voice crackled through the communicator, full of shock, "That's impossible! The plant network's information capacity is far insufficient!"

"We don't need to carry everything," Su Yu's eyes shone terrifyingly, "only the 'seeds.' Each civilization only needs its core 'civilization question'— why do they exist? What have they loved? What are they afraid of losing?"

She glanced at the countdown on the holographic console: 14 minutes 22 seconds.

"Then we shut down the device, halt the homogenization wave. Using Earth's time, we'll help these civilization 'seeds' find new homes—perhaps the new form of the evolved blank bodies, perhaps a new plan after the Seran homeworld changes its mind, perhaps…"

She paused, "Perhaps a hundred years from now, our own children will have the ability to reactivate this device."

Han Qing began the connection.

The rainbow conduit extended from his body, pierced the submarine hull, and stabbed into the massive silver vortex. The collective consciousness of the three hundred Seran tuners quivered violently, like a dried riverbed suddenly hit by a flood.

"You are… the new tuners?" an ancient, weary voice sounded.

"We are students." Han Qing replied in Seran language, simultaneously injecting Human Emotional Frequency, "We have learned the curriculum you left. Now we apply… to become teachers."

A prolonged silence.

Then, three hundred voices rose together, like a symphony finally reaching its finale:

"Evidence."

Han Qing looked at Su Yu.

Su Yu closed her eyes, the rainbow‑colored seed in her chest burst—not physically, but all the roots, all the conduits, all the Emotional Frequency she had amassed as a tuner surged through the rainbow conduit toward the device.

What she "played" was not the organ, but the memories of Earth's civilization from the past seven years:

The light when Chen Mo sacrificed;

The rainbow when geometry learned love;

The first sunflower Xiao Yu planted;

The embrace when Lao Zhao found his son;

The sparks of iron hammer town forging;

The oath on the reservoir dam;

The song from deep within the mine;

The final sacrifice of the seventeen faded ones…

All the "inefficient," "redundant," "Error Signal" yet "living" moments converged into a torrent, pouring into the device.

The three thousand civilization light points began moving toward Earth.

Countdown: 7 minutes 05 seconds.

The device initiated its shutdown sequence. The silver vortex's spin slowed, the homogenization wave's energy supply was cut off. Outside the porthole, the deep‑sea creatures that had been fading suddenly regained color— faint, but undeniably color.

Three hundred Silan tuners' consciousness, like soldiers completing their final mission, began to dissipate one by one.

But before they dissipated, each person left a final sentence—not in Silan language, but in the native tongue of the civilization they had preserved:

"Thank you."

"Goodbye."

"Please remember us."

When the last tuner dissipated, the device shut down completely. The silver vortex became an ordinary, silent underwater structure.

Three thousand civilizations' points of light, like a migrating flock, passed through the rainbow meridian, flying toward the sea surface, toward the plant network, into the depths of each connector's consciousness.

The submarine began to surface.

Oxygen countdown: three minutes twelve seconds.

Han Qing slumped in his seat, the rainbow meridian dimmed like dying embers. The silver "medal" on his chest had completely vanished, replaced by a pulsing, seven-colored heart.

"I have received……" he said weakly, "the 'Civilization Question' of three hundred civilizations. They want us…… to help them find the answer."

Su Yu grasped his hand. Both of their hands were trembling.

On the holographic platform, a message suddenly popped up from the assessment ship—not a cold official notice, but text leaking from the crack in the team leader's mirrored face, carrying obvious emotional fluctuations:

"The mother star has observed the 'Civilization Cradle' transfer event."

"Assessment Committee vote result: research faction proportion rose to 89%, standardization faction dropped to 11%."

"New resolution: Earth civilization gains qualification as 'Civilization Diversity Incubator'. Observation period extended to three hundred years."

"Meanwhile, the Silan mother star requests…… to dispatch observers to learn how to 'hatch eggs'."

The submarine broke through the sea surface.

Sunlight poured into the porthole.

In the distance, the gray-white waves were receding—not disappearing, but retreating like tide back to the deep sea, leaving a clear but no longer advancing boundary on the coastline.

Meanwhile, in the temporary school on the shore, three of the thirty-seven blank bodies suddenly spoke in unison, using three completely different languages never before seen on Earth:

"We have awakened."

"Where is this?"

"Who are you?"
