The thunderous impact echoed across the underground arena.

Thousands of spectators fell silent.

The giant’s eyes widened.

His smile vanished.

And then—

his feet left the ground.

For the first time in hundreds of battles, the undefeated champion was airborne.

The crowd watched in disbelief as the enormous gladiator flew backward like a rag doll.

CRAAAAASH!

His massive body smashed through a stone pillar.

Fragments exploded across the arena floor.

Dust filled the air.

The giant crashed into the arena wall and slid to the ground.

Silence.

Absolute silence.

Nobody moved.

Nobody breathed.

The boy remained standing exactly where he had thrown the punch.

Calm.

Unmoved.

As if nothing unusual had happened.

Then the giant groaned.

The crowd collectively gasped.

He was still alive.

But barely.

Blood was not visible, yet his entire body trembled.

His arms struggled to support his weight.

His knees shook.

The strongest fighter in the kingdom looked confused.

Terrified.

Humiliated.

“What…”

The giant coughed.

“What are you?”

The boy didn’t answer.

Instead, he slowly brushed dust from his torn shirt.

The crowd began whispering.

“Did you see that?”

“Impossible.”

“No child could do that.”

“Maybe it was luck.”

The giant heard the whispers.

His face darkened.

For years he had ruled the underground arena.

No challenger had ever survived more than a few minutes against him.

Kings had paid fortunes to watch him fight.

Generals had admired him.

Nobles feared him.

And now—

an eleven-year-old boy had punched him across the arena.

In front of everyone.

The humiliation burned worse than any wound.

Rage filled his eyes.

The giant slowly stood.

The stone beneath his feet cracked.

The crowd backed away.

Because they recognized that look.

Many fighters had seen it before.

None survived afterward.

“You embarrassed me.”

His voice echoed through the arena.

The boy remained silent.

“You should have stayed on the ground.”

The giant picked up a massive iron hammer from the arena floor.

The weapon was taller than most men.

Its iron head alone weighed more than the boy.

The spectators immediately cheered.

Now things would return to normal.

No child could survive that.

No matter how strong.

The giant raised the hammer.

“Let’s see if you can punch this.”

Then he charged.

BOOOOM.

BOOOOM.

BOOOOM.

Each step shook the arena.

The hammer came down.

The crowd screamed.

The weapon smashed into the stone floor.

CRAAAAASH!

The entire platform exploded.

Stone shards flew everywhere.

A massive crater appeared where the boy had been standing.

The spectators jumped to their feet.

Many thought the fight was over.

Then they saw him.

The boy stood behind the giant.

Completely unharmed.

The giant froze.

Slowly turned.

Confusion spread across his face.

The boy had moved.

Not just moved.

Vanished.

The strike should have hit.

Everyone saw it.

Yet somehow the child stood several yards away.

Calm as ever.

The giant attacked again.

And again.

And again.

The hammer smashed the arena floor repeatedly.

Stone exploded.

Dust filled the air.

The arena shook violently.

But every strike missed.

The boy seemed untouchable.

Like smoke.

Like a shadow.

Like he could see every attack before it happened.

The crowd stopped cheering.

Fear replaced excitement.

Because something felt wrong.

Very wrong.

Even the nobles in the balconies noticed it.

Among them sat King Aldric himself.

Hidden beneath a dark hood.

Watching.

Studying.

The king narrowed his eyes.

Then his expression changed.

Recognition.

The elderly royal advisor beside him noticed immediately.

“What is it, Your Majesty?”

The king remained silent.

His eyes never left the boy.

“I’ve seen that before.”

The advisor frowned.

“Seen what?”

The king’s voice grew quiet.

“The movement.”

A cold feeling settled over him.

Because there was only one fighting style in the kingdom that looked like that.

One.

And it had supposedly disappeared fifteen years ago.

The style of the Royal Guardians.

An elite order destroyed during a rebellion.

Every member had been killed.

Or so everyone believed.

Down below, the giant finally lost patience.

He roared with fury.

Then threw the hammer.

The gigantic weapon spun through the air toward the child.

The crowd screamed.

The boy raised one hand.

The hammer stopped.

Stopped completely.

Frozen in midair.

Silence spread through the arena.

Nobody understood.

The giant stared.

His mouth slowly opened.

The hammer trembled.

Then turned around.

And flew back.

Toward him.

The giant barely had time to react.

CRAAAAASH!

The weapon slammed into his chest.

The impact launched him across the arena again.

This time he crashed through two stone walls.

The underground arena shook.

Dust rained from the ceiling.

The crowd erupted into chaos.

People stood.

Pointed.

Shouted.

No longer watching a fight.

Watching something impossible.

Then a deep horn echoed through the arena.

MOOOOOOOM.

Every head turned.

The massive iron gates behind the arena were opening.

Slowly.

Heavily.

The giant looked up from the rubble.

His face suddenly turned pale.

For the first time all day—

he looked afraid.

Genuinely afraid.

The boy noticed.

“What is it?”

The giant didn’t answer.

The gates continued opening.

Darkness waited beyond them.

Then a growl emerged.

Low.

Ancient.

Terrifying.

The spectators fell silent.

Even the king stood.

Because everyone knew what lived behind those gates.

The arena’s secret.

The reason no prisoner had ever escaped.

The Black Beast.

A monstrous creature used by arena masters to execute dangerous fighters.

Nobody had seen it in years.

Rumors claimed it wasn’t even alive anymore.

The rumors were wrong.

Two glowing red eyes appeared in the darkness.

The crowd panicked instantly.

People rushed toward exits.

Nobles abandoned their seats.

Guards drew weapons.

The giant scrambled backward through the rubble.

“No…”

His voice trembled.

“No, not that thing.”

The boy remained still.

Watching.

Waiting.

The enormous creature stepped into the light.

Gasps echoed across the arena.

It was larger than a horse.

Covered in black fur.

Its claws dug deep grooves into stone.

Ancient scars covered its body.

Heavy chains dragged behind it.

The arena master appeared above the stands.

Laughing.

A cruel old man dressed in gold robes.

“I’ve changed my mind.”

The crowd looked toward him.

The arena master pointed at the boy.

“Kill him.”

The beast growled.

The giant suddenly shouted.

“WAIT!”

Everyone turned.

The giant struggled to his feet.

His entire body hurt.

His pride was shattered.

Yet something had changed.

His eyes moved from the boy to the beast.

Then back again.

The giant remembered something.

Years ago.

A small child.

A burning village.

Bandits.

A boy who saved lives.

A boy he never thanked.

His eyes widened.

Could it be?

Slowly, he looked at the child standing across the arena.

The same eyes.

The same face.

Older now.

But unmistakable.

The realization hit him like lightning.

The boy wasn’t a stranger.

The boy had saved his life years ago.

Before he became a gladiator.

Before fame.

Before glory.

The giant turned toward the arena master.

“No.”

The crowd froze.

The arena master frowned.

“What?”

The giant stepped forward.

Standing between the beast and the child.

“I said no.”

The arena master laughed.

“You work for me.”

The giant tightened his fists.

“Not anymore.”

The arena erupted with whispers.

Nobody had ever defied the arena master.

Nobody.

The old man’s smile vanished.

“Then both of you die.”

The beast charged.

The ground shook.

The crowd screamed.

The giant charged too.

For the first time in years—

not to entertain.

Not for gold.

Not for victory.

To protect someone.

The giant slammed into the monster.

BOOOOOOM!

The collision shook the entire arena.

Stone cracked.

Dust exploded.

The giant roared.

The beast roared louder.

The battle was unlike anything the crowd had ever seen.

But within seconds it became obvious.

The giant was losing.

The monster was stronger.

Faster.

Older.

One claw strike ripped through the giant’s armor.

Another sent him crashing across the arena floor.

The crowd watched helplessly.

Then—

a hand grabbed the giant’s shoulder.

The boy.

Standing beside him.

The giant looked up.

“Run.”

The boy shook his head.

“No.”

The beast charged again.

The giant prepared for impact.

But it never came.

The creature suddenly froze.

The entire arena fell silent.

The monster’s red eyes widened.

Its breathing slowed.

Then, unbelievably—

it lowered its head.

The giant stared.

The crowd stared.

The king stared.

The beast wasn’t attacking.

It was bowing.

To the boy.

A deep ancient voice echoed through the arena.

Not spoken aloud.

Heard inside every mind.

“The Heir.”

The crowd gasped.

The king’s face turned white.

The giant looked confused.

But the old royal advisor collapsed to his knees.

Because he recognized the word.

A word from forgotten legends.

A word not spoken for generations.

The Heir.

The lost descendant of the Royal Guardians.

The child thought dead fifteen years ago.

The rightful protector of the kingdom.

And suddenly everyone understood why the giant’s celebration had been premature.

This had never been an ordinary fight.

The arena master hadn’t thrown a child into the arena.

He had thrown the kingdom’s greatest secret into it.

And now—

every person inside the underground arena was about to discover the truth.
