Chapter Fifteen: The Dandelion Clock

Page (1/3)

Cain stood on the grassy lawn of Greenwich Park, twirling the blue seed between his fingers. The morning dew dampened the tips of his shoes, while the air carried the scent of freshly trimmed grass mingled with the caramel aroma from a distant coffee cart. Everything was too normal—so normal that it unsettled him.

“Sir, would you like to feed the pigeons?”

A little girl in a red dress held out a paper bag full of corn kernels, looking up at him. Sunlight filtered through her fluffy brown hair, casting scattered golden specks across her cheeks. As Cain crouched down, he noticed a pale blue infinity-shaped birthmark on the inside of her left wrist.

“What’s your name?”

“Lina.” The girl shook her wrist, the birthmark almost transparent in the sunlight. “Mom says it’s a kiss from an angel.”

Cain’s pocket watch suddenly vibrated in his pocket—not the urgent alarm from before, but a gentle hum, like a bee skimming over a lavender field. When he took out the watch, Lina gasped with delight—the blue sand on the dial was forming the shape of a dandelion.

“Is this a magic watch?”

“Something like that.” Cain gently pressed the crown, and the dandelion seeds scattered into the air. “It helps find special people.”

A glowing seed landed on Lina’s infinity birthmark. She blinked, her pupils shimmering with a nebula-like blue. “Are you here to find Sister Little Key?”

The dewdrops on the lawn rose into the air, forming countless lenses around them. Each droplet reflected a different scene: the star observatory atop Tokyo Tower, the underground vaults of the Cairo Museum, the maintenance cabin of the London Eye... All places shared one thing—a blue wind chime hanging in view.

“She’s waiting for you at the planetarium,” Lina’s voice suddenly took on a gravity beyond her years, “but first, you have to pass the dandelion test.”

The girl pulled a copper key from her red dress pocket. The teeth of the key were shaped like a Möbius strip. When she inserted the key into the grass—literally pushing it into the turf—the ground rippled like water. Three blue dandelions sprouted rapidly, growing and blooming before his eyes.

“Choose one.” Lina’s tone shifted, carrying the unique cadence of Sister Little Key. “But choose carefully.”

The seeds on the first dandelion reflected Cain’s face—though a female version; the second’s seeds formed a pattern of London Bridge; the third was the most peculiar, each seed a miniature pocket watch.

Cain reached out to touch the third dandelion. The moment his fingertips grazed the fluff, the entire plant transformed into a stream of light flowing into his pocket watch. Inside the glass dial, a delicate star map appeared, seven constellations connected by golden lines, with Libra’s position pulsating steadily.

“Greenwich Observatory.” Lina brushed off her dress and stood up, her voice returning to childlike innocence. “I go there every Saturday to watch the stars!”

Cain looked toward the white-domed building on the hill. To an ordinary person, it was just a typical planetarium, but through his eyes, it was shrouded in a translucent blue veil like the Northern Lights, and the rooftop weather vane was a motionless ouroboros statue.

“Wait.” Cain called after the girl who was already running away. “What if I hadn’t chosen the third dandelion?”

Lina turned back with a smile. In the sunlight, her shadow suddenly split into three: a little engineer clutching gears, a merchant holding an hourglass, and a female scientist in a white lab coat.

“Then you’d take another path.” The three shadows answered in unison. “Every path leads to the stars, just with different constellations.”

On the open ground outside the observatory, a dozen children lined up to receive constellation manuals. Cain noticed blue marks on their wrists or necks—∞ birthmarks, hourglass tattoos, gear pendants... One bespectacled boy even had a tiny LED implanted on the back of his neck, displaying the number 7.100011.

“Mr. Aldrin?” A staff member in uniform checked the holographic tablet in his hands. “The special guided tour is waiting for you in the Meridian Hall.”

The prime meridian marker at the center of the hall glowed blue. As Cain stepped over the brass line, the floor beneath turned transparent, revealing a rotating starry map below. Seven staff members, each wearing a differently colored infinity badge, simultaneously pressed constellation reliefs on the wall.

The floor slid open silently, revealing a spiral staircase. A familiar mix of scents filled the air: the burnt tang of welding metal, the mineral scent of obsidian, and the moist sweetness unique to Tokyo’s cherry blossom season. This was the scent of all time-tree nodes combined.

The basement’s scale far exceeded the observatory’s surface building. Cain stood on a circular platform overlooking a multi-level mechanical forest—gear clusters twisting like vines around steel frames, fiber optics hanging like willow branches, and in the center, a transparent column housing a miniature time tree whose roots connected to seven terminals of distinct styles.

“Welcome home, Gardener.”

Little Key emerged from behind a quantum computer. She looked about fifteen or sixteen, with blue hair braided with fiber optics and miniature pocket watch earrings dangling from her earlobes. Most astonishing were the seven holographic figures floating behind her—Maggie, Hassan, Edgar, Leon, and three unfamiliar faces—all depicted as semi-transparent quantum states.

“We’ve simplified the operating system.” Little Key tapped the console, and a globe projection appeared, its surface covered in glowing networks. “Now the time tree’s roots cover 92% of human settlements.”

Maggie’s projection drifted over. “London node is running smoothly. The rusted gear clusters have been converted into memory storage.”

“The Cairo obelisk generates 3,000 new paradoxes a day.” Hassan’s image flickered, the hole in his chest still visible but fringed with golden light strands. “Enough to keep the Purifiers busy for centuries.”

Cain’s pocket watch flew automatically to the console, slotting into an empty port. The globe expanded, sprouting hundreds of new branches, each ending with a glowing dandelion-shaped cluster.

“Sprouts of new timelines.” Little Key touched one light cluster, enlarging it to reveal a scene inside—a parallel world’s Greenwich Park, where a female Cain spoke with engineer-dressed Lina. “We no longer repair broken timelines but cultivate new possibilities.”

Edgar’s projection suddenly floated forward. “There’s a small problem.” He pulled up surveillance footage showing a black-clad Thorne adjusting a massive device on one timeline. “The old stubborn ones have activated 'Ragnarok 2.0.'”

Thorne turned toward the camera, his right eye glowing ominously red. “Found you, Aldrin.” His words pierced the dimensional barrier, ringing out in real space.

All projections blurred for a moment. Little Key swiftly closed the channel. “They’ve evolved—able to back-contaminate nodes through observation.”

“We need new defenses.” Cain said without hesitation, his hands already typing code on the console. Only when the screen displayed “Paradox Firewall Activated” did he realize he didn’t remember ever learning this.

Little Key smiled. “Muscle memory is more reliable than brain memory.”

She opened a hidden compartment in the console and pulled out an hourglass-shaped container, inside which flowed red and blue light particles. “Backup memories of all Gardeners. If you’re deleted on any timeline...” She flipped the hourglass, “...you’ll be reborn from here.”

Cain suddenly understood how Hassan and the others maintained their quantum states. This basement wasn’t a command center, but a memory greenhouse nurturing countless possible versions of themselves.

“One last question.” He pointed to the floating time tree. “If the Purifiers find this place...”

Little Key’s pupils glowed with streaming blue data. “Then we execute the ‘Dandelion Protocol.’”

She waved, bringing up a holographic diagram: the time tree would self-destruct, but each root segment would transform into light particles carrying memory seeds, scattering like dandelions across all timelines. The Gardeners, carrying the core consciousness, would temporarily reside within the dreams of ordinary people.

“Just like when we first hid in your memories.” Maggie’s projection whispered.

Suddenly, dull thuds echoed from the observatory’s roof. Dust drifted down as Cain noticed all projections shift into alert—Edgar drew his antique shotgun, Hassan’s chest wound began to glow, and even the gentle Leon adopted a fighting stance.

“They arrived seventeen minutes earlier than expected.” Little Key’s voice remained calm, but all the fiber optics in her hair turned a warning red. “Dad, it’s time to choose.”

Three transparent capsules rose from the console, labeled “Guardian,” “Wanderer,” and “Sower.”

The first held a neural interface helmet; the second contained a pocket-watch-shaped dimensional jumper; the third was the simplest—just a copper key and a packet of blue seeds.

The thuds grew louder. As Cain grasped the key, the other two capsules locked automatically. Little Key smiled in relief. “I knew you’d choose this one.”

She pressed the blue button on the main console. The entire basement hummed like a pipe organ as the time tree’s roots began to glow. Cain felt the key in his hand grow hot, its teeth morphing until they settled into the shape of a dandelion.

“Remember,” the seven projections spoke together, their voices merging into a strange harmony, “time is a garden, and every Gardener is a seed nurtured by it...”

As the ceiling collapsed, Little Key slipped the hourglass into Cain’s pocket. A warm force enveloped him, as if he were sealed inside a feather-filled time capsule. The last image he saw was the Purifiers leaping through the breach, while Little Key opened her arms; her blue braids unfurled into countless fiber optics weaving a net that enveloped the entire mechanical forest.

Then came a dreamless sleep, until the soft cooing of pigeons woke him.

Cain lay on a bench in Greenwich Park, the morning dew dampening his trench coat. Lina crouched beside him, feeding pigeons, her red dress flickering like a small flame in the sunrise.

“You kept smiling while you slept.” The girl handed him a blue candy. “Did you dream of something happy?”

Cain touched his pockets. On the left, the warm pocket watch; on the right, the hourglass and a packet of seeds. The Greenwich Observatory stood quietly in the distance, its rooftop weather vane turning normally, betraying no sign of the extraordinary.

“Yes,” he said. “I dreamed of a beautiful garden of time.”

As Lina skipped away, Cain noticed her shadow occasionally split in the sunlight—sometimes an engineer, sometimes a merchant, other times a scientist in a white coat. When he raised his hand to shield his eyes, he glimpsed faint golden patterns on the inside of his arm, shaped like the stem of a dandelion.

The pocket watch chimed softly. The blue sand on its face formed a line of text: “The next Gardener has awakened.”
