Grand Return System-Chapter 20: A Thousand Years of Quiet Thunder

A Thousand Years of Quiet Thunder

Bang—

The sound wasn’t heard with the ears. It rolled through Selena’s body — a deep, resonant crack — like winter ice splitting across a frozen lake.

Her breath caught.

And then she felt it.

She had crossed the threshold.

Onyx Realm — first star.

Mana surged through her meridians, clean and fierce. Her heart fluttered — half disbelief, half exhilaration.

Four days... Only four days after joining Celestis Academy...

Those who entered the Acedmy alongside her were still hovering at the first star of Mana Requirement, trembling through slow meditations.

Yet she —

She stood in the Onyx Realm.

"Hu..."

Behind her, Leon slowly withdrew his hands, the warmth leaving her back like fading embers.

His voice, low and steady:

"Don’t get distracted. Sit. Breathe. Consolidate your foundation — or the instability will haunt your future cultivation."

His tone carried no doubt — only calm authority.

Selena nodded at once.

"Alright. I understand..."

She crossed her legs again, snow-white robe flowing softly around her thighs, pale blue sash rising and falling with each breath. The faint chill from her Divine Ice Bones spread outward, making the air crisp and still.

She began circulating the Purple Mist Mana Sutra, letting Mana complete a full Heavenly cycle through every meridian.

One cycle.

Two.

Three.

With each pass, the wild storm inside her quieted — transforming into a deep, quiet reservoir.

More than half the energy had already been refined, and her mind grew clear — tranquil — luminous.

Leon didn’t disturb her.

He turned away, expression faintly thoughtful, and returned to his seat.

Then — inside his mind:

"System."

A crisp chime responded.

[Ding...]

And beneath that calm voice, another presence stirred:

[Bestowal complete.][Cooldown engaged.][Grand Return reward... calculating.]

Leon’s lips curved — almost lazily.

The storm had only just begun.

[You have bestowed ten years of cultivation upon your student.][Critical Hit Return available.][Activate?]

Leon whispered in his heart:

"Activate."

A pause.

Then the system rang out like a bell.

[Congratulations, host.][You triggered a 100-times critical strike.][Reward gained — 1,000 years of cultivation.]

Leon inhaled sharply.

"A thousand years..."

A quiet laugh escaped him.

Ten years out.

A thousand years back.

Where else in the heavens could someone find a bargain like that?

He leaned back, eyes narrowing. 𝐟𝗿𝐞𝚎𝚠𝐞𝚋𝕟𝐨𝚟𝐞𝕝.𝕔𝕠𝚖

"With a thousand years — and my current physique — I should be able to tear through the GrandMaster Realm barrier... and step into the King Realm."

The thought sent a ripple of heat through him.

"Come on then. I’m ready."

He closed his eyes.

The training hall seemed to hold its breath.

Mana surged.

Not like Selena’s — bright and cold — but dense, ancient, crushing. It poured into his bones, into the sinew of his muscles, into the depths of his prefecture sea.

Every limb tightened.

Veins burned.

His body felt like a furnace with the lid clamped shut.

He gritted his teeth.

"Hiss... this tearing sensation... energy pouring in..."

He guided everything with ruthless precision, funneling it into the heart of his prefecture sea — where the Purple Lotus of Great Principal slowly spun like a quiet star.

The moment the energy touched it —

It drank.

It devoured.

And then it began to feed back, returning purer power — over and over — like endless tides.

His cultivation climbed.

Fourth star of GrandMaster Realm.

Fifth.

Sixth.

Seventh.

The rise did not slow.

Eighth star.

Ninth star.

Mana howled through his prefecture sea, pressing against its boundaries, trying to burst free. His spiritual core trembled — cracking — then dissolving into liquid light.

Leon locked his jaw, sweat sliding down his temples.

Not yet. Hold. Compress it. Refine it.

For a long moment, the only sound was the faint rustling of wind beyond the hall — the world itself seeming to lean close.

And then —

Everything snapped.

A thunderous shift tore through his inner world.

Power surged toward his organs — heart, liver, spleen, lungs, kidneys — forming radiant springs within each.

Each spring pulsed once.

Twice.

Then stabilized.

Boom—

The change washed over him like a cocoon splitting open.

Silence followed — heavy and profound.

Leon took a long, steady breath.

"Ah... comfortable."

From this moment forward —

He was no longer the "useless" teacher of Amethyst Summit Division.

He had stepped fully into the King Realm.

One step more, and the distant Saint Realm waited beyond.

Exactly as he expected — one thousand years of cultivation had been just enough to pierce the GrandMaster ceiling and cross the threshold.

He didn’t reach Saint Realm — but greed wasn’t wisdom. Strength built too fast cracked foundations.

Slow. Solid. Certain.

When he finally opened his eyes again...

He was different.

Not louder — quieter.

His aura didn’t surge outward anymore — it vanished, buried deep inside, impossible to read. Yet around him drifted something faint and unreal — like distant celestial mist.

Not arrogance.

Not power flaunted.

Simply—

Presence.

A being who could walk through the world calmly, untouched.

And Leon knew:

This aura wasn’t born purely from the King Realm.

Some of it came from the Immortal Body Refine Elixir still lingering in his bones, polishing everything from inside out.

He breathed once.

The hall calmed with him.

And somewhere deep within, power continued to ripple quietly...

Like thunder rolling under the horizon.
