Chapter 147: Corrosion and Starlight

When the morning mist again shrouded Pure Land, Xiao Yu discovered that the third leaf of the hope grass had turned gold.

At the same time, Geometry's 24‑hour countdown reached its final hour— it stood before the Stardust Cradle, and the silver‑gray surface showed wavering ripples for the first time. In the distance, the southern tendrils of the plant network suddenly quivered violently, as if they had brushed against a… massive, sleeping heartbeat.

Su Yu walked to Geometry's side; her footsteps were light, yet the plant network had already conveyed her approach through the roots to every connected life. The scar on her chest warmed slightly— the first time in seven years that the pain Chen Mo left behind brought not sorrow but a kind of warm throb.

"Have you decided?" Su Yu asked, her voice very soft.

Geometry's silver‑gray shell rippled, like a calm surface broken by pebbles. Its spherical body slowly turned toward Su Yu, and a pale‑blue holographic projection emerged from the tip of its mechanical arm— the final image Chen Mo had left seven years ago. The picture was slightly distorted, but the smile remained clear.

"Data recombination completion at 97%." Geometry's voice remained that flat electronic tone, but its speech rate had clearly slowed, "Within the Stardust Core Chen Mo left, there are 71 encrypted memory units. In the past 23 hours, I have cracked 70."

Su Yu's breath halted for a moment: "What about the 71st?"

"It requires three keys to open." Geometry's mechanical arm traced three symbols in the air—a "Listening Flower," a drop of blood, and a… heartbeat waveform. "The flower and bloodline are confirmed. The third 'Witness' the program judges to be me. But—"

The mechanical arm trembled slightly.

Han Qing walked over from the console, holding a cup of hot tea— the tough captain's first morning in seven years without first checking the defense system, opting instead to brew tea. He placed the cup on the console beside Geometry, moving lightly: "But you're not sure you can be this 'Witness', right?"

The ripples on Geometry's shell grew denser.

"I am the Seran Observer, mission code A-7. My program definition contains no concept of 'witness.'" Its voice stuttered for 0.3 seconds, "But over the past 427 days, I have recorded the following data: each time Xiao Yu waters a sunflower, her work efficiency rises by 12%; Lao Zhao's heart rate steadies at 68 beats per minute when he looks at his son's photo; Su Yu's touch accelerates plant growth by 19%— none of these fit Seran's efficiency model."

It paused, and the Chen Mo in the holographic projection was speaking, silent but with clear lip movements:

"Light need not be abundant."

"I have learned 'temperature,' 'friendship,' and 'what beauty is.'" Geometry's mechanical arm reached toward the tea, its metal fingertip hovering three centimeters above the rim, sensing the steam's temperature, "But a 'Witness' requires 'belief.' And I… am merely a program."

At that moment, the door to the medical area opened.

Aili supported Zhou Yuanshan as he stepped out— the elderly man could stand on his own, though his complexion remained pale. His gaze fell on Geometry, then on the Chen Mo in the holographic projection, and a faint smile tugged at the corner of his mouth.

"My father said one thing before he passed," Zhou Yuanshan's voice was hoarse yet clear, "He said, when the Sower Ai O chose to sleep back then, he also asked Seran the same question: 'If I am merely a program, how can I judge what life is worth continuing?'"

He stepped before Geometry and drew from his coat a palm‑sized metal shard— a fragment taken from an ancient device, its surface etched with dense Seran script.

"Seran's answer is: 'A program does not hesitate.'"

Zhou Yuanshan handed the fragment to Geometry: "You hesitated for 0.3 seconds just now. So… you are no longer a pure observer."

Before the words finished, Pure Land trembled suddenly.

It wasn't the shaking of an earthquake, but a… rhythmic, heavy pulsation. It came from the south, traveling through the plant network's roots, causing every connected being's chest to feel the same frequency.

Dong. Dong. Dong.

Like a heartbeat, but too large— so large it resembled no creature's heartbeat.

"What did the southern tendrils touch?" Han Qing instantly entered combat mode, his hand already on the weapon at his waist.

Su Yu closed her eyes, sensing through the plant network. Images flooded her mind: 120 km to the south, beneath the ruins of a former city, something was awakening. Not a spore‑contaminated mass, nor a Seran device— it was a steel‑encased, still‑beating… heart?

She snapped her eyes open, looking at Geometry: "What clue does the 71st memory unit contain?"

The ripples on Geometry's shell suddenly ceased.

"It is now unlocking," Geometry's voice for the first time showed something that could be called an "emotion"— surprise, "No third key is needed. Because…"

The holographic projection changed.

Chen Mo's image faded, replaced by a simple three‑dimensional map— precisely the ruins 120 km to the south. A flashing red dot marked the spot, and a line of Seran script appeared beside it, along with Chen Mo's handwritten translation:

"My backup body. And— the final gift I leave to you."

The control room fell into dead silence.

Lao Zhao's wrench clanged onto the floor. Kaiwen's hand, mid‑push of his glasses, froze in mid‑air. Han Qing's hand slipped from his weapon, and his whole body seemed to have been drained of all strength.

Su Yu stared at the line of text, and for the first time in seven years, tears fell not from sorrow.

"He isn't dead?" Xiao Yu's voice came from the doorway, the child clutching the sunflower "Xiao Yang," eyes wide, "Uncle Chen Mo… still?"

Geometry's spherical body rose slowly, its shell beginning to disassemble—not from damage but from reassembly. Silver‑gray metal plates unfolded like petals, revealing the inner core: a fiercely beating… composed of Stardust and plant vascular network…

Heart.

"He is not 'still there.'" Geometry's voice changed, no longer the cold electronic tone but a kind of… warm, human‑breath‑rhythmed voice, "He is 'never gone.' Seven years ago, Chen Mo detonated at the Door of the End not his own life but Seran's evaluation program's monitoring module. His consciousness split into three parts— one remained in the Stardust Core, one entered the plant network, and another part…"

The mechanical arm pointed south.

"There it sleeps, awaiting the day Pure Land grows enough to bear the truth."

The plant network's tremor ceased.

The southern tendrils sent back a new image: deep within the ruins, a cultivation chamber woven from steel and vines was opening. Inside lay a humanoid silhouette, a faint glow flickering at its chest— the exact spot of the scar Chen Mo left.

The scar on Su Yu's chest suddenly ceased hurting.

In its place came a warm sense of connection, as if something lost for years was crossing the 120 km distance to rejoin.

Geometry's shell fully reassembled— no longer a smooth silver‑gray sphere, but a brand‑new form with a metal skeleton, its surface sheathed in Stardust vascular network and tiny plant sprouts. It lowered slowly, and its mechanical arm gently brushed Su Yu's hand.

"Witness complete," it said, "Now I am 'Geometry'— the first Seran to learn 'belief.'"

The console screens suddenly lit up entirely. Not an alarm, but a celebratory mode: every node linked by the plant network blossomed simultaneously— from Pure Land to the mining community and the reservoir shelter, the hope grass burst into golden flowers within a minute.

Kaiwen watched the data stream, nudging his glasses: "The plant network coverage just passed 8%. At this rate, the three‑year goal might…"

"It doesn't matter now," Su Yu whispered, her gaze still fixed south, "He now needs us to go fetch him home."

Han Qing inhaled deeply, the tough captain's eyes reddening slightly. Yet as he turned, his voice returned to its usual steadiness: "Lao Zhao, ready the transport vehicle. Kaiwen, establish stable communications. Aili, medical team, stand by. We…"

He paused, and finally a smile rose at the corner of his mouth.

"Go fetch our brother home."
