Chapter 160: Root Filaments on the String

The underground space trembled under the scouring of newborn colors, but what trembled was not the rock, but the air itself—colors that had never existed in the human spectrum were being played as sound: the hue of dawn was a long organ bass, the root hue a deep cello vibrato, newborn green a crisp harp pluck.

Su Yu's chest scar split completely open.

It wasn't the wound bursting open; it was like a seed breaking soil—grayish scabs peeled away to reveal colorful veins underneath. Those veins were like living root filaments, growing from deep within the scar, spreading upward along her chest to the collarbone and downward to the ribs. Each vein emitted a faint but distinct frequency, resonating with the organ's chords.

The "root string" of the tuner." Lin Shouzhuo's voice sounded unusually calm in the trembling air, "According to the records left by Ao, when a civilization needs a new tuner, the predecessor's legacy chooses the most suitable successor—not by bloodline, but by 'resonance purity'."

He walked up to Su Yu, his cloudy eyes reflecting the glowing root filaments on her chest: "Chen Mo left the last fragment of his consciousness in you, not to make you miss him, but to tune your 'string.' Now... what do you hear?"

Su Yu closed her eyes.

She heard it—not with her ears, but with those root filaments. The colorful veins acted like antennas, picking up frequencies from the entire Earth's plant network: the anxiety of hope grass became a soothing C major, the steadfastness of the reservoir dam turned into a firm F minor, the resentment deep in the mine became an impassioned G-string vibrato…

And there was the final segment of frequency left by Chen Mo: an unfinished melody hanging in midair, waiting to be continued.

Han Qing suddenly dropped to one knee.

It wasn't an injury, but a kind of gravity shift—the newborn colors' frequency altered the local gravitational field. He gritted his teeth and held on, but the old wound on his left arm began to ooze… a silver liquid.

"Captain!" Li Xiaofeng rushed over.

"Don't touch it!" Kaiwen blocked him, scanning the silver liquid with his terminal, "They are nanomolecular formatting units… the Examiner's 'snow' has seeped into the wound. They are reconstructing the captain's tissue from within!"

Han Qing's forehead beaded with sweat, but his expression didn't change: "How long until complete conversion?"

"At this rate… three hours." Kaiwen's voice tightened, "but the pain will increase exponentially—Sera's formatting program will first strip away pain nerves, then touch, then temperature…"

"Then we'll solve the problem within three hours." Han Qing pushed himself up, his movements a bit stiff but still steady. He looked at Su Yu: "What do you need?"

Su Yu opened her eyes, the colorful root filaments casting mottled light and shadow on her face: "I need… to understand what a tuner is."

Lin Shouzhuo walked to the pipe organ, his fingers hovering over the keys—this time the keys solidified into translucent crystal keys. He pressed three chords, and new images appeared on the rock wall:

Not a human, but a Sera.

But it was different from the geometry and the researchers' silver spheres—it had a 'face,' though blurry, one could make out the features. It stood on a barren planet, holding an instrument similar to a violin, playing toward the starry sky.

"Ao Sera Thiss." Lin Shouzhuo said, "The last-generation tuner of the Sera civilization. Three thousand years ago, when the homeworld council voted to delete the emotion module, he fled with this 'Starstring Zither'."

The image shifted: Ao came to Earth and discovered early humans. He watched primitives dance around a campfire, mothers soothing infants to sleep, warriors sacrificing to protect their tribe… each time, he used the Starstring Zither to record the emotional frequency of that moment.

"He realized that emotion is not a flaw of civilization, but its 'chord.'" Lin Shouzhuo's voice carried an ancient echo, "Without emotion, civilization is just a string of correct code. With emotion, code gains meaning—even if that meaning is sometimes painful, sometimes inefficient, sometimes contradictory."

The tunnel suddenly shuddered violently.

It wasn't the organ's resonance vibrating, but an external impact—the Examiners were attacking the ground. The gray-white snowflakes turned into silver drills, boring down from a hundred meters above the surface.

"It's going to straight-up reformat this place!" Kaiwen stared at the terminal, "Drilling through time… forty minutes!"

Han Qing immediately deployed: "Old Zhao, take people to reinforce the upper structure! Li Xiaofeng, use the leftover pipes from the chemical plant as channels to disperse the drill's energy! One-Eye, your team has demolition experience—calculate the best interception point!"

Everyone sprang into action.

Only Su Yu didn't move. She stood before the pipe organ, the root filaments on her chest already grown to her shoulders. Those veins began to extend automatically, like living tendrils, lightly resting on the keys.

The keys lit up.

Not the soft light when Lin Shouzhuo played, but a blinding light, as if about to ignite.

"You're afraid." Lin Shouzhuo suddenly said.

Su Yu's hand trembled: "I've never even learned piano…"

"A tuner doesn't play an instrument; they play the heartbeat of civilization." The old man stepped beside her, gripping her trembling hand—his hand was cool, but his grip steady: "Chen Mo chose you not because of what you can do, but because of who you are—you're the one who plants flowers in the ruins, the one who remembers every child's name, the one who would walk a hundred kilometers for a glimmer of light."

He guided her hand to press a key.

The key corresponded to the frequency of 'sorrow'.

The underground space instantly filled with the sound of rain—not real rain, but the memories of all human civilization about parting: a mother sending her child off, a soldier bidding farewell to his homeland, lovers' final embrace, Chen Mo turning back to say, 'Wait for me to return'…

Each drop of rain carried warmth.

Su Yu's tears fell, and in the glow of the colorful root filaments, the droplets refracted a color never seen before—that of 'inheritance silver,' not the cold silver of Sera, but a warm silver like the faded edge of an old photograph, still clear.

"Now, press another key." Lin Shouzhuo said, "The emotion you most want to respond to."

Su Yu closed her eyes.

She recalled that rainy night seven years ago, when Chen Mo last embraced her and said: "If one day you become a seeder, remember—the power of a seed is not in breaking ground, but in knowing why to break ground."

Her fingers fell.

She pressed the key for 'hope'.

All the organ's pipes burst forth simultaneously.

It wasn't a sound explosion, but a burst of color—the underground space instantly filled with hues never seen before: seven-colored flowers bloomed on the walls, those flowers not plants but solidified light; golden letters floated in the air, not any language, but a direct projection into the brain of 'meaning'; even the vibrations from the Examiner's drill were tinged with a pale bluish-purple, like a bruise fading.

Most astonishing were the root filaments on Su Yu's chest—they suddenly surged like vines, climbing the pipe organ, boring into the pipes and fusing with the instrument's body. Each filament became a new string, each string playing automatically.

She was becoming part of the organ.

Or rather, the organ was becoming part of her.

Lin Shouzhuo stepped back and bowed deeply—this was the ancient seeder's rite for a tuner: "The inheritance is complete. Now you are the second Earth tuner after Ao. Your first piece… who do you want to play it for?"

Su Yu opened her eyes.

Her pupils turned into seven-colored whirlpools, but her gaze remained her own—determined, gentle, with a hint of stubbornness.

"Play it for the one above." She looked toward the tunnel's top, "Play it for the civilization that thinks emotion is an error program."

The colorful root filaments shot upward violently.

They pierced rock, soil, and the Examiner drill's silver barrier, like countless reverse-growing rainbows, surging toward the surface.

Above ground, the Examiners' ship was launching a second wave of drills.

But the drills disintegrated on contact with the root filaments—not physical destruction, but 'meaning deconstruction': the nanomolecular units making up the drills suddenly began to doubt themselves, asking 'Why drill?' 'What is formatting?' 'Is emotion really inefficient?'

The Examiners' pure silver bodies showed their first cracks.

Not physical cracks, but programmatic ones—its logic core began to falter. Because it detected that the frequencies conveyed by those colorful root filaments were rewriting its basic cognition protocols. That wasn't an attack, but… a question.

One after another, the questions, in the form of emotional frequencies, surged straight into its processor:

"If there were no sorrow, how would you know what peace is?"

"If there is no anger, how do you know what is justice?"

"If there is no love, you do all this... for what?"

The spaceship began to shake.

And behind the spaceship, on Earth's geosynchronous orbit, a larger shadow slowly emerged—the assessment ship of Therlan Homeworld, arriving on time.

It did not attack, merely hanging there silently, like the eye observing a specimen.

On the hull's surface appeared a line of Therlan script, translated into all Earth languages, projected onto the atmosphere:

"Abnormal civilization 'Earth', and the newly risen tuner 'Su Yu'."

"Final assessment, now beginning."

"Test item: Prove your existence, worthy of being allowed to continue the 'Error Signal' onward."

Underground, the roots on Su Yu's chest began to contract, returning to the scar—but the scar was no longer a wound, but a seven-colored seed slowly pulsing.

She lifted her head, as if she could see the massive ship on the orbit through a hundred meters of rock.

"Good." she whispered, "Then let me prove it to you."
