Heartfire Reborn” — A Fantasy Romance of the QSB6.7 Engine

1. The Awakening

Lin Yan sought the core to save his collapsing sect; only the QSB6.7 Heartfire could ignite the Heaven Machine Cauldron and reverse disaster.

When he reached the mountain’s heart, the core pulsed like a beating heart—ancient runes glowing with warmth.

Light burst outward.
A silver-haired girl emerged, ethereal, her brow glowing with a soft golden flame.

“I am Suran,” she said.
“Spirit of the QSB6.7 Heartfire.”

Lin Yan froze.

The legendary engine core… had a soul.
A beautiful one.

“You awakened me,” Suran whispered.
“And now… our destinies are bound.”

2. The Heartfire Pact

To control the QSB6.7’s power, Lin Yan had to form a Heartfire Pact with her.

During the ritual, Suran placed her hand gently on his chest.

“From this moment on, you are the one who ignites my fire.
And I… am the guardian of your strength.”

A surge of power roared through Lin Yan’s body—like an invisible engine awakening inside his chest.
Steady. Deep. Relentless.

The heartbeat of the QSB6.7.

Training with Suran at his side, every flame, every breath, every spark synced with hers.
And somewhere in that rhythm… affection quietly bloomed.

3. The Spirit Overload

Dark forces learned of Suran’s awakening and attacked to steal the Heartfire.

During the battle, Lin Yan pushed the Heartfire beyond its limits to shield her—
the power tore through his body, threatening to burn him alive from within.

Suran caught him, trembling.

“You’ll die if you push the Heartfire any further!”

He smiled weakly.
“You said our destinies were bound… so what’s wrong with protecting you?”

Her heart shattered.
Tears fell—her first in a thousand years.

As the Heartfire spiraled toward destruction, Suran made her choice.

She sacrificed her spirit form to seal the rampaging power.

“Lin Yan… thank you for believing in me.
If there is another life… let me be your Heartfire again.”

She dissolved into light and vanished into his chest.

The core calmed.
But Suran was gone.

4. Reborn in the Heartfire

Three years passed.
Lin Yan became the strongest machine-soul cultivator of the Nine Provinces.
But he never smiled again.

One night, a faint hum rose from within his chest—
warm, familiar, alive.

Then a soft voice:

“Lin Yan… I’ve returned.”

Suran had been reborn as the living consciousness within the QSB6.7 Heartfire.
No longer separate.
No longer distant.

Just one heartbeat away.

Lin Yan closed his eyes, feeling the warmth spread through him.

“Suran… from now on, no matter how many times the Heartfire burns or breaks—
I’ll face it with you.”

The mountains trembled as the Heartfire flared, brighter than ever.

No longer a cold ancient engine—
but the shared heart of two souls destined to ignite each other.
