Chapter 100 — The Heart Beneath the Forest

Kael stood completely still.

The Verdant Serpent's enormous body coiled around the ruined forest, black-and-green scales reflecting the pale energy rising from beneath the earth.

Its eyes remained fixed on him.

“Now you must decide whether you are willing to damage what is beneath me to do so.”

Kael looked down.

The forest floor was no longer ordinary soil.

A vast network of glowing green lines spread beneath the roots.

They formed circles.

Channels.

Conduits.

And at the very center—

A gigantic structure.

Kael's eyes narrowed.

Ancient Verdant Containment Structure

Grade: Legendary

State: Active

Integrity: 71%

Primary Function: Beast Restraint

Secondary Function: Central Prison Stabilization

Authority Sources: 5

Current Territory Synchronization: 31%

Kael's expression darkened.

“So that's what you've been protecting.”

The Serpent lowered its head.

“Yes.”

Kael immediately noticed something strange.

The creature wasn't attacking.

It was waiting.

Not because it was afraid.

Because it wanted Kael to make a choice.

Kael stared at the structure.

Three of the surrounding mana hubs were barely functioning.

The regeneration network had already collapsed to a fraction of its original efficiency.

Yet the containment structure was still maintaining itself.

That meant one thing.

The remaining authority wasn't coming from the three hubs.

Kael's eyes moved across the glowing network.

“Five authority sources…”

He remembered the information from earlier.

Three had been identified.

But two had remained hidden.

His eyes narrowed.

“Those two aren't part of the regeneration system.”

The Serpent remained silent.

Kael slowly smiled.

“I've been fighting the wrong battle.”

The creature's expression changed.

Kael raised his hand.

The Darven Origin Blade rose from the earth and floated beside him.

The Vanguard Armor covered his body.

The V-01X hovered near his shoulder.

[Spatial Stability: 91%]

[Mana: 31%]

Kael's breathing became steady.

He had less than half of his Legendary Immortality remaining.

He couldn't waste it.

He looked at the containment structure again.

If he damaged it carelessly, the central prison could destabilize.

If he ignored it, the Serpent would continue regenerating.

There had to be another way.

Kael closed his eyes.

Mana Control.

His consciousness expanded through the ground.

He could feel the network.

Thousands of mana channels.

Some broken.

Some weakened.

Some still flowing.

He followed them.

One channel.

Then another.

Then another.

Kael's eyes opened.

“There.”

Deep beneath the forest—

something was pulsing.

Not like a heart.

Like a machine.

A small secondary structure was connected to the main containment system.

It was hidden beneath several layers of stone.

And it wasn't feeding the Serpent.

It was feeding the prison.

Kael immediately understood.

“The two unknown authority sources…”

He looked toward the Serpent.

“You were using one as your power source.”

The Verdant Serpent's eyes narrowed.

“And the other…”

Kael's gaze shifted downward.

“…belongs to the prison.”

Silence.

That was enough confirmation.

Kael clenched his fist.

“I don't need to destroy the containment structure.”

The V-01X rotated into Configuration III.

Spatial Anchor.

A faint blue ring formed around the weapon.

Kael pointed downward.

“I only need to separate you from the part you're using.”

The Serpent finally moved.

Its enormous body surged forward.

The forest exploded into motion.

“Too late.”

Kael fired.

BOOM!

The Spatial Anchor struck the earth.

A wave of distorted space spread through the ground.

For a moment, the entire network froze.

The Verdant Serpent stopped.

Kael stared.

The anchor had connected.

But—

The containment structure reacted.

[Foreign Spatial Authority detected.]

[Containment response initiated.]

Green energy erupted from the ground.

Kael was thrown backward.

He twisted in midair.

The Vanguard Armor absorbed most of the impact.

He landed and immediately rolled.

A massive root crashed down where he had been standing.

Kael fired the MP-01.

RATATAT!

The shots struck the roots.

The roots stopped for only a second.

Then they regenerated.

Kael's eyes sharpened.

“Of course.”

He switched to V-01X Configuration II.

Mana Disruption.

Three rounds fired.

They struck the regenerating roots.

The green energy flickered.

The regeneration slowed.

Kael moved.

He sprinted beneath the collapsing branches.

The Serpent followed.

Its massive body moved through the forest with impossible speed.

Kael knew a direct confrontation would accomplish nothing.

So he changed targets.

Not the Serpent.

The network.

A cluster of green crystals appeared beneath the roots.

Kael raised his hand.

Metal Control.

The metallic components embedded in the containment structure shifted.

Several ancient clamps loosened.

The Serpent suddenly stopped.

Its eyes widened.

“You…”

Kael pulled harder.

CRACK!

A metallic locking plate separated from the structure.

The entire network trembled.

The Serpent roared.

The sound shook the forest.

Kael was thrown backward.

His vision blurred.

The Verdant Serpent charged.

Kael raised his Origin Blade.

The impact sent him flying.

He crashed through several trees and landed on the ground.

Pain spread through his body.

His armor integrity dropped.

[Vanguard Armor Integrity: 43%]

Kael slowly stood.

The Serpent was already approaching.

Its scales glowed.

Green energy gathered inside its body.

Kael recognized the attack.

Regeneration wasn't its only ability.

It could compress the entire territory's energy into a single strike.

Kael's pupils contracted.

“Not good.”

He activated Shadow Configuration.

Dark energy covered the armor.

The Serpent attacked.

Kael vanished sideways.

A column of green energy obliterated the area where he had stood.

Kael appeared behind a tree.

The tree immediately began withering.

Kael's eyes widened.

“Even the energy itself is dangerous.”

He didn't hesitate.

He raised the V-01X.

Configuration IV — Suppression.

A powerful shot slammed into the Serpent's side.

The beast barely reacted.

Another shot.

Then another.

The Serpent turned.

Its eyes locked onto Kael.

It opened its mouth.

A torrent of green energy erupted.

Kael ran.

The attack followed him.

Left.

Right.

Up.

The forest behind him was transformed into a wave of collapsing vegetation.

Kael finally jumped.

He fired a Spatial Anchor into the ground.

The recoil pushed him sideways.

The beam missed.

Kael landed on a stone pillar.

He looked down.

The pillar was part of the containment structure.

And there—

He saw it.

A small green sphere.

No larger than a fist.

It pulsed with energy.

Kael's eyes widened.

“That must be one of them.”

He immediately reached out with Metal Control.

Nothing happened.

He frowned.

It wasn't metal.

Of course.

He needed another solution.

Kael opened the information window.

[Ancient Verdant Containment Structure]

Authority Source 1: Beast Regeneration

Authority Source 2: Territory Regeneration

Authority Source 3: Territory Authority

Authority Source 4: ???

Authority Source 5: ???

Kael stared.

The System still couldn't identify the final two.

That meant they weren't normal energy sources.

They belonged to something beyond the structure's recognized categories.

Something ancient.

Kael's eyes shifted.

A thought entered his mind.

“Administrator Authority.”

His hidden authority.

Kael reached toward the containment sphere.

The ring on his finger reacted.

A faint silver light spread across his hand.

The sphere pulsed.

Once.

Twice.

Then—

[Administrator Authority recognized.]

Kael froze.

[Foreign authority detected.]

[Compatibility: 4%]

[Warning: Administrator Authority is insufficient for full access.]

Kael smiled.

“I don't need full access.”

He pushed harder.

The sphere flickered.

The Verdant Serpent sensed it immediately.

“No!”

The creature attacked.

Kael didn't move.

He concentrated everything on the sphere.

The world around him disappeared.

His consciousness entered the structure.

For one moment—

Kael saw something impossible.

A vast chamber.

Hundreds of chains.

Three enormous beasts.

And beneath them—

A fourth prison.

At its center stood a black tower.

The same black tower he had seen before.

But now he saw something else.

One of the chains connected directly to the Verdant Serpent.

Another connected toward the Shadow Domain.

A third extended into the Bone Domain.

And all three converged at the black tower.

Kael's breathing stopped.

“So that's it…”

The three beasts weren't merely imprisoned.

They were components of the same system.

The Serpent spoke from somewhere outside.

“Get out!”

Kael ignored it.

He followed the fourth chain.

It led to a sealed chamber.

Something was behind it.

Something powerful.

Something that made the entire network feel like a prison built around a single threat.

Then—

A voice whispered.

“Administrator.”

Kael's eyes widened.

It wasn't the Serpent.

It wasn't Nightfang.

It wasn't the System.

The voice came from the black tower.

Kael immediately withdrew.

His consciousness returned to his body.

The Serpent was already upon him.

Kael barely raised his blade.

BOOM!

He was driven into the ground.

The stone beneath him cracked.

His armor integrity dropped again.

[Vanguard Armor Integrity: 19%]

Kael coughed.

His vision shook.

The Serpent lowered its head.

“You should never have looked inside.”

Kael stared at it.

“You heard it too.”

The beast remained silent.

Kael understood.

The Verdant Serpent knew about the entity.

Perhaps all three beasts did.

But none of them wanted to speak about it.

Kael wiped the dirt from his face.

“Then let's finish this.”

He stood.

The Serpent stared at him.

“You can't defeat me.”

Kael smiled faintly.

“I know.”

The Serpent's eyes narrowed.

Kael raised his hand.

The V-01X floated upward.

Then the GL-02.

Then the damaged MP-01.

Then the Origin Blade.

Every piece of metal around him rose.

The entire battlefield became a weapon.

The Serpent looked around.

“What are you doing?”

Kael answered quietly.

“Changing the battlefield.”

The first weapon fired.

BOOM!

The GL-02 launched a compressed mana projectile toward the Serpent's head.

The beast deflected it.

The second weapon fired immediately.

The PR-02.

A precision round struck a weakened scale cluster.

CRACK!

The Serpent recoiled.

Kael used Metal Control to redirect the bullet's remaining momentum.

It curved.

Then struck a second damaged point.

The Serpent roared.

Kael smiled.

“Your scales aren't invulnerable.”

The beast lunged.

Kael switched to close-combat mode.

The V-01X folded into a compact blade configuration.

Kael met the attack.

CLANG!

The impact sent him sliding backward.

The Serpent struck again.

Kael blocked.

Again.

Again.

Again.

His arms shook.

His body couldn't match the creature's power.

So he stopped trying to.

He redirected.

Every strike.

Every movement.

Every opening.

He remembered the Shadow Lion.

He remembered the lesson.

Never fight power with power.

Fight structure.

Kael stepped backward.

The Serpent followed.

Straight toward the damaged section of the containment structure.

Kael's eyes sharpened.

“Now.”

He thrust the Origin Blade into the ground.

Metal Control spread through the ancient metallic framework.

The buried locking mechanisms activated.

The damaged containment structure suddenly shifted.

A massive ring rose from the ground.

The Serpent became trapped inside it.

“What have you done?”

Kael gritted his teeth.

“I learned.”

The ring began tightening.

The Serpent's territory energy surged.

The containment structure resisted.

Both powers collided.

The forest shook.

Kael nearly lost control.

His mana dropped rapidly.

[Mana: 12%]

Too much.

He couldn't maintain it.

The Serpent began breaking free.

Kael's eyes widened.

“Not enough…”

He looked at his weapons.

Then at the containment ring.

Then at the Serpent.

An idea appeared.

Kael grabbed the Spatial Anchor.

He fired directly into the center of the containment ring.

Space locked.

The ring stopped moving.

The Serpent stopped.

For one second—

Everything became still.

Kael raised the Origin Blade.

“I don't need to defeat your body.”

The blade began glowing.

“I only need to break your control.”

He struck the metallic framework.

BOOM!

A wave of energy spread through the structure.

The Serpent's connection to the territory weakened.

[Territory Authority: 31% → 18%]

The beast roared.

Kael struck again.

BOOM!

[Territory Authority: 18% → 9%]

The Serpent's movements slowed.

Kael attacked a third time.

But this time—

The structure resisted.

A black crack appeared across the green energy.

Kael froze.

The containment system was starting to destabilize.

He immediately stopped.

“Damn.”

He had gone too far.

The Serpent smiled.

“You finally understand.”

Kael stared.

“If the structure breaks…”

“The prison weakens.”

Kael clenched his fist.

The serpent continued.

“And if the prison weakens enough…”

Kael looked toward the distant black tower.

He understood.

The thing inside would have more freedom.

He couldn't destroy the structure.

He couldn't destroy the Serpent.

And he couldn't allow the territory to restore itself.

Kael closed his eyes.

Think.

There had to be another option.

Then he remembered the three regeneration hubs.

He didn't need to destroy the containment system.

He only needed to disconnect the Serpent from it.

Not break.

Disconnect.

Kael opened his eyes.

“That sphere.”

The Serpent's expression changed.

“You noticed.”

“The fourth authority source.”

Silence.

Kael raised his hand.

Administrator Authority surged.

The containment sphere reacted.

The entire forest shook.

[Attempting authority override.]

[Compatibility insufficient.]

[Alternative detected.]

[Metal Control synchronization possible.]

Kael stared.

His bloodline could interact with the structure.

Not because it was stronger.

Because the structure itself used ancient metal.

Kael smiled.

“That's enough.”

He reached into the structure.

Metal Control spread through the buried framework.

One lock.

Then another.

Then another.

Kael didn't break them.

He rotated them.

Reversed them.

Changed their direction.

The Serpent's connection slowly weakened.

[Beast-Territory Synchronization: 46%]

[42%]

[36%]

[29%]

The Serpent roared.

Its body shook.

The forest trembled.

But the containment structure remained stable.

Kael continued.

[21%]

[15%]

[8%]

Then—

[Beast-Territory Synchronization: 4%]

Everything stopped.

The Serpent stared at Kael.

For the first time—

Kael saw genuine uncertainty in its eyes.

The beast's body was still powerful.

Its level was still beyond his.

Its physical strength was still overwhelming.

But it had lost control of the territory.

Kael breathed heavily.

“You're alone now.”

The Serpent slowly raised its head.

“Yes.”

Green energy gathered around its body.

“But so are you.”

Kael's smile disappeared.

The remaining forest went silent.

The Serpent's scales began changing.

The green light became darker.

Its eyes turned completely black.

The System appeared.

[Warning.]

[Target has abandoned Territory Authority.]

[Target is entering True Beast State.]

Kael's pupils contracted.

Another message appeared.

[Verdant Serpent — Restriction Removal: 100%]

[Original Combat Ability: Unsealed.]

Kael stared.

The beast's body began changing.

The ground beneath it cracked.

The forest around them withered.

The enormous serpent slowly raised its head until it towered above the trees.

Its scales became darker.

Its body became more streamlined.

The strange green patterns across its skin turned white.

A faint crown-like structure appeared above its head.

Kael's breathing became heavier.

He had spent nearly forty minutes learning how to weaken the Serpent.

And now—

He had forced it to reveal its real form.

The Serpent spoke.

Its voice was deeper.

Older.

More terrifying.

“You wanted to fight the beast without its territory.”

Kael tightened his grip.

“Now you have your wish.”

The creature opened its jaws.

“But you forgot something.”

Kael stared at it.

“What?”

The Serpent smiled.

“I was imprisoned because even without my territory…”

“I was too dangerous to leave free.”

The forest exploded.

Kael raised his sword.

The Serpent vanished.

Kael's eyes widened.

Too fast.

Something struck him.

His vision turned white.

His body flew across the forest.

The Vanguard Armor shattered.

Kael disappeared into the trees.

The System flashed.

[Critical damage detected.]

Kael hit the ground.

He tried to move.

Nothing.

The Serpent appeared above him.

Kael stared upward.

Then—

His vision went dark.

Five seconds later—

Kael reformed.

He gasped.

His body restored.

His armor reconstructed.

His weapons appeared beside him.

The Serpent was waiting.

It had seen everything.

Kael slowly stood.

The timer appeared.

[Legendary Immortality Remaining: 42:51:03]

Kael stared at the beast.

The Serpent stared back.

Neither moved.

Then Kael smiled.

“You finally showed me your real power.”

The Serpent narrowed its eyes.

Kael picked up the Origin Blade.

“Good.”

The blade hummed.

V-01X rose beside him.

“Now I can start learning again.”

The Verdant Serpent's smile faded.

Kael lowered his stance.

The next battle would not be about territory.

It would not be about regeneration.

And it would not be about containment.

It would be—

Kael versus the true Verdant Serpent.

And for the first time since entering the pocket world—

Kael had no battlefield advantage left.

Only his immortality.

His weapons.

His bloodline.

And everything he had learned from dying.

The Serpent moved.

Kael charged.

Their attacks collided.

And the second phase of the battle began.
