The body of the Sea Beast drifted slowly away.
The waves carried it back into the depths as if nothing had happened.
But Thalren couldn't look away.
That single strike.
No weapon.
No effort.
And yet… it ended everything.
He stood there, silent, staring at the place where the creature had vanished.
Behind him, Kael walked back toward the shore as if it meant nothing.
"Stop staring," he said.
Thalren didn't move.
"…How did you do that?"
Kael paused.
Then sighed slightly.
"That's not something you learn by asking."
Thalren finally turned.
"Then how do I learn it?"
Kael looked at him.
For a moment, his usual calm expression shifted.
Something deeper appeared.
"You survive long enough to understand it."
The answer wasn't satisfying.
But it was real.
---
The rest of the morning passed in silence.
No training.
No orders.
Just the sound of waves and wind.
Thalren sat near the shore, his sword resting beside him.
His mind replayed the fight again and again.
Every movement.
Every mistake.
Every moment he hesitated.
"…I was too slow," he muttered.
Kael, sitting a few steps behind him, responded without looking.
"You were."
Thalren clenched his fist.
"My attacks didn't work."
"They didn't."
"I couldn't even damage it properly."
"You couldn't."
Thalren turned, frustrated.
"Then what was I supposed to do?!"
Kael finally looked at him.
"Die."
The word hit hard.
Thalren froze.
Kael stood up slowly.
"That creature was beyond your current level."
He walked closer.
"You were not meant to win."
Thalren's jaw tightened.
"…Then why didn't you stop me earlier?"
Kael stopped in front of him.
"Because you needed to feel it."
"Feel what?" Thalren snapped.
Kael's voice became sharper.
"The difference."
Silence.
The wind passed between them.
Thalren looked away.
"…I hate that feeling."
Kael nodded.
"Good."
The boy frowned.
"What?"
"That feeling is what pushes you forward."
Kael turned toward the sea again.
"Without it, you stop growing."
Thalren slowly looked back at the horizon.
The endless water stretched beyond his sight.
Somewhere out there were creatures far stronger than what he had faced.
And people like Kael…
Who could destroy them with a single movement.
"…Then teach me," Thalren said quietly.
Kael didn't respond immediately.
Instead, he picked up a small stick from the ground.
He drew a line in the sand.
"Cross it."
Thalren blinked.
"That's it?"
"Just cross it."
The boy stepped forward.
The moment his foot touched the line—
Kael moved.
Faster than Thalren could react.
A sharp strike hit his shoulder and knocked him off balance.
He stumbled back.
"What was that?!"
Kael returned to his position calmly.
"Again."
Thalren frowned and stepped forward.
The same thing happened.
A strike.
Fast.
Precise.
He couldn't even see it clearly.
"Again."
Thalren tried a third time.
This time he focused.
Watched Kael's body.
His breathing.
His stance.
The moment he stepped forward—
He tried to move faster.
But Kael was still faster.
Another strike.
He fell back again.
Frustration rose.
"This is impossible!"
Kael shook his head.
"No."
Thalren stood up.
"I can't even see your movement!"
Kael looked at him calmly.
"That's because you're looking at the wrong thing."
Thalren paused.
"What do you mean?"
Kael pointed at him.
"You're watching my body."
"Then what should I watch?"
Kael tapped his own chest.
"Intent."
Thalren frowned.
"That doesn't make sense."
Kael sighed.
"It will."
He stepped back.
"Again."
Thalren took a deep breath.
He steadied himself.
Then stepped forward.
This time, he didn't focus on Kael's hands.
Or his feet.
He focused on the feeling.
The moment before movement.
The shift in presence.
The slight change in air.
Then—
He saw it.
Not clearly.
But enough.
Kael moved.
And this time—
Thalren reacted.
Barely.
He raised his arm just enough to block part of the strike.
The impact still pushed him back.
But he didn't fall.
Kael stopped.
"…Good."
Thalren's eyes widened slightly.
"I… saw it."
Kael nodded.
"That is the beginning."
Thalren steadied his breathing.
"What is this called?"
Kael crossed his arms.
"Instinct."
The word stayed in the air.
"Every strong fighter has it," Kael continued.
"It's what allows you to react before you think."
Thalren looked at his hands.
"…Like I felt during the fight."
"Yes."
Kael pointed toward the sea.
"Out there, thinking too much gets you killed."
Thalren nodded slowly.
"So I need to trust this feeling."
Kael gave a small nod.
"Exactly."
The training continued.
Again and again.
Thalren stepped forward.
Again and again.
Kael struck.
Slowly…
Very slowly…
Thalren began to react better.
Not perfectly.
Not even close.
But enough to see the difference.
By the time the sun began to set, his body was exhausted again.
He collapsed onto the sand, breathing heavily.
"…This is harder than fighting that thing."
Kael chuckled slightly.
"It's supposed to be."
Thalren looked up at the sky.
"…Kael."
"Yes."
"…How strong are you?"
For a moment, Kael didn't answer.
Then he looked toward the horizon.
"Not strong enough."
Thalren blinked.
"What?"
Kael's expression didn't change.
"There are things out there…"
"…that even I cannot defeat."
The words were calm.
But heavy.
Thalren slowly sat up.
"…Stronger than you?"
Kael nodded once.
"Yes."
The boy looked toward the endless sea again.
His determination didn't shake.
If anything—
It grew stronger.
"Then I'll surpass all of them."
Kael glanced at him.
No smile.
But no doubt either.
The waves rolled quietly across the shore.
And far beneath the dark waters…
Something ancient continued to watch.
Because the boy was changing.
And soon—
He would no longer belong to the shore.
