The iron chest gave off a low hum.
Kael stood still with one hand resting on the lid, his eyes fixed on the old black symbol carved into the metal. The sound coming from inside was weak at first, almost like a sleeping beast breathing in the dark.
Then it grew stronger.
Owen took a step back.
"Lucas… what did you do?"
Kael did not answer. His attention was on the system screen that had appeared in front of his eyes.
Partial Absorption possible.
Warning: Unknown material may resist control.
Proceed?
Kael's gaze sharpened.
"Proceed."
The chest vibrated.
A thin line of dark energy leaked from the cracks along the edge. It was cold, sharp, and strange, like smoke that had weight. The air inside the hidden room grew heavy, and Owen shivered.
The door behind them shook again.
Bang.
The sound of metal hitting metal echoed through the room.
The guards were trying to break in.
Owen's face went pale. "They're going to get in."
Kael's hand pressed harder against the chest.
"Then they'll be too late."
The system flashed again.
[Absorbing unknown energy…]
Kael felt a sudden chill race up his arm. His fingers tightened. For a moment, it felt like he was touching ice, not metal. Then a pulse shot through his body, and a flood of information entered his mind.
Not words.
Not memories.
A feeling.
He saw fragments.
A dark hall.
Men in cloaks.
A glowing crystal.
A body strapped to a table.
Pain.
Screams.
Kael's eyes narrowed.
He pulled his hand back slightly, disturbed by what he had seen.
This was not normal treasure.
This was something used in experiments.
Dangerous experiments.
The chest gave a final heavy thud, and the humming stopped.
A new panel appeared.
Absorption complete.
Obtained: Shadow Residue x1
Evolution Points gained: 2
New skill fragment unlocked: Shadow Sense
Kael blinked once.
Two points.
That was more than he expected.
His body felt a little lighter already, as if something inside him had awakened and sharpened his senses. He looked toward the dark corners of the room and realized he could now feel movement more clearly, even in near darkness.
The system was changing him faster than he had thought.
Another bang came from the door.
This one was followed by a crack.
Owen flinched.
"Lucas, they're getting in!"
Kael turned to the chest again. "Step back."
"What?"
"Back."
Owen obeyed immediately.
Kael placed both hands on the chest lid. The moment he lifted it, a cold wave of black smoke rushed out. Owen covered his mouth and stumbled backward.
Inside the chest were three things.
The first was a small black crystal, larger than the one Kael had taken from the assassin.
The second was a bundle of old papers tied with red string.
The third was a strange metal key with a narrow engraved head.
Kael picked up the crystal first.
Item detected: Shadow Core Fragment
Type: Rare Energy Material
Effect: Boosts darkness-based abilities
Warning: Highly unstable
Kael's eyes narrowed.
Darkness-based abilities.
This would be useful.
He took the papers next.
The pages were old and covered in codes, names, and numbers. Most of it looked like trade records at first glance, but Kael's sharp eyes quickly noticed the repeated symbols and hidden notes written in the margins.
These were not normal business records.
These were hidden movement logs.
People had been taken.
Materials had been moved.
And payments had been made in secret.
Kael flipped through the pages quickly.
His expression grew colder with each line.
"You found something useful?" Owen asked in a whisper.
Kael did not answer immediately.
He read one more page, then another.
At the bottom of the third page was a name.
Varian Holt
Kael's eyes stopped there.
So that was it.
Lord Varian was not just a rich noble. He was involved in secret trade, hidden experiments, and likely murder. Lucas had discovered too much, and that was why he had been poisoned.
Kael folded the papers neatly and tucked them under one arm.
Owen stared at him. "You know that name?"
"Yes."
"You look angry."
Kael glanced at him.
"I have reason to be."
Before Owen could ask more, the wooden door behind them finally broke open.
A guard's shoulder hit the frame and shoved it aside.
The first man into the room was Captain Reth. He stepped in with two guards behind him, all three armed and ready.
Reth's gaze swept over the hidden room and landed on the open chest.
His face changed instantly.
So did Kael's.
Reth had not expected anyone to see this.
For a brief moment, surprise flashed across the captain's face. Then it turned into cold anger.
"Well," he said, "it seems the fool was not as useless as we thought."
Owen took a frightened step back. "Captain…"
Reth ignored him.
His eyes were on Kael.
"You should have died when the poison hit you," he said calmly.
Kael looked at him without fear.
"So you knew about that too."
Reth gave a low laugh. "Of course I did."
One of the guards behind him shifted uneasily. He seemed unsure about what was happening, but he stayed silent.
Reth took another step into the room.
"You were never meant to leave your room again," he said. "You were supposed to die quietly, and the matter would have ended there."
Kael's hand moved slightly near the sword.
"But then you started digging around."
Reth's eyes narrowed. "You should have stayed weak."
Kael's voice was low. "Weak people die either way."
A strange silence followed.
Then Reth smiled.
Not a friendly smile.
A cruel one.
"That is true," he said. "But not all weak people die the same way."
He raised one hand.
The guards behind him instantly moved into position.
Owen looked terrified. "Lucas—"
Kael cut him off without looking away from Reth.
"Stay behind me."
Owen swallowed and quickly backed into the wall.
Reth drew his weapon, a short steel blade with a heavy hilt.
"You've already seen too much," he said. "Hand over the papers and the crystal. If you cooperate, I might let your little friend leave alive."
Kael's grip tightened.
"The moment you walked in," Kael said, "you already planned to kill us."
Reth shrugged.
"Correct."
The guards attacked.
Kael moved first.
The room was narrow, which made the fight harder for the guards and better for him. He stepped to the side, letting the first blade slice through empty air, then drove the hilt of his sword into the man's wrist. Bone cracked. The guard shouted and dropped his weapon.
The second guard lunged immediately after, but Kael had already seen the movement.
Shadow Sense activated.
The world sharpened around him.
He could feel the guard's weight shift before the attack came. He leaned back, avoided the blade by inches, and swung low. The iron sword struck the guard's leg and knocked him off balance.
Owen stared wide-eyed.
Kael had barely moved, but it looked almost unreal.
Reth's eyes narrowed.
"So that's how it is."
He rushed forward.
This time, Kael could feel the difference.
Reth was faster than the other guards. Stronger too. He was not a normal man. His strikes carried skill and force, and his expression was calm as he attacked, as though he had killed many times before.
Kael blocked the first strike and felt his arm numb from the impact.
Strong.
Too strong for this body.
Another strike came from the side. Kael twisted away just in time, but the blade still cut across his shoulder.
Pain flared.
The wound was shallow, but real.
Kael's eyes narrowed.
Minor regeneration worked instantly. Warmth spread through the cut, and the bleeding slowed almost at once. The pain was still there, but weaker.
Reth noticed it too.
His smile faded.
"What kind of trick is that?"
Kael did not answer. He was already studying Reth's movements.
The captain was skilled, but arrogant. He thought of this as a cleanup job, not a real fight. That arrogance was his weakness.
Kael stepped back once, then allowed his breathing to slow.
The system panel flickered in the corner of his vision.
Evolution Points available: 2
Kael made his choice at once.
"Enhance speed and reaction."
Evolution Point consumed.
Speed and reaction enhanced.
A surge ran through his legs and spine.
His vision seemed to open wider. The room felt clearer. Reth's movements were still strong, but Kael could now read them better, react faster, and place his feet with more precision.
The next attack came.
Kael ducked under it, slipped to the side, and struck Reth's elbow.
The captain grunted.
Kael followed with a second slash, then a third. Reth blocked both, but the force pushed him back a step.
Owen gasped.
The guards were already struggling to rise after their first injuries.
Reth's expression darkened.
"Impossible," he said.
Kael's voice was steady. "You're not the only one who can grow."
Reth snarled and charged again.
This time he attacked with full force.
Kael stepped back, then suddenly moved forward instead of retreating.
Reth blinked.
He had expected Kael to keep distance.
That moment of surprise was all Kael needed.
He drove his sword up and struck Reth's wrist.
The captain's blade slipped from his hand.
Before Reth could react, Kael kicked him in the chest and sent him crashing into the wall behind him.
The room shook.
Owen nearly shouted.
Reth coughed once, then slowly stood.
Blood ran from the corner of his mouth.
His face had changed completely now.
The calm mockery was gone.
Now there was only hatred.
"You little rat…"
Kael pointed the sword at him.
"Tell me who ordered Lucas killed."
Reth laughed harshly.
"You still think this is about one servant?"
Kael's eyes sharpened.
Reth wiped the blood from his mouth and glared at him.
"You found a piece of the truth, so now you think you're special? Fine. I'll tell you something before I kill you."
He leaned forward slightly.
"Lord Varian did not act alone."
Owen gasped softly.
Kael did not move.
Reth continued, his voice low and ugly.
"There are nobles, officers, and traders involved. People much higher than you. Lucas only found part of the operation. The boy was lucky to die before he learned too much."
Kael's expression turned cold enough to freeze the room.
So it was bigger than he expected.
Much bigger.
Reth watched his face and smiled.
"Yes. That's right. The world is rotten at the top. And the weak like you exist only to be crushed under it."
Kael's eyes darkened.
"You made one mistake."
Reth frowned. "What mistake?"
Kael lifted the papers in his free hand.
"You told me the truth."
Reth's expression changed.
Kael took one slow step forward.
"Now I know where to start."
Reth shouted and lunged.
But Kael was ready.
He threw the small black crystal into the air.
Reth blinked in surprise.
Kael slashed downward at the same time.
The blade hit the crystal.
It shattered.
Dark energy exploded outward in a burst of smoke and black sparks, filling the whole room.
Reth coughed and stumbled back, his vision blocked.
Kael moved through the smoke like a shadow.
He could feel the room now. Every shape. Every movement. Every breath.
One guard was down.
One was crawling.
Reth was trying to push through the smoke blindly.
Kael reached him first.
He struck Reth hard in the ribs.
The captain gasped.
Kael followed with a second strike to the jaw.
Reth fell to one knee.
Kael placed the sword at his throat.
The room slowly cleared.
Reth looked up at him in shock and rage.
Owen stared at the scene, barely able to breathe.
Kael's voice was quiet.
"Now you talk."
Reth spat blood onto the floor.
"You think this changes anything?"
Kael did not answer.
Reth's mouth twisted into a vicious grin.
"Kill me, then. Another will come. And then another. You cannot fight everyone."
Kael's gaze stayed cold.
"I don't need to fight everyone."
He pressed the sword a little closer.
"I just need the first one to talk."
Reth's eyes trembled for the first time.
He was afraid now.
Good.
Kael could use that.
But before he could speak again, footsteps thundered overhead.
Many footsteps.
Too many.
Then a voice shouted from above.
"Open the lower passage!"
Another voice followed.
"They're down there!"
Owen turned pale.
Kael listened carefully.
The estate was mobilizing fast.
This was no longer a hidden problem. It had become an emergency.
Reth heard it too, and his expression changed.
"You fool," he hissed. "You've already trapped yourself."
Kael looked toward the ceiling.
Then back at Reth.
"Maybe."
The footsteps came closer.
The door to the hidden room was already broken. More guards would arrive any second.
Kael made a quick decision.
He reached down, grabbed Reth by the collar, and dragged him up against the wall.
"Listen carefully," he said.
Reth glared at him but did not resist.
Kael's voice lowered.
"You will tell me everything you know about Lord Varian, the hidden trade, and the people involved."
Reth smiled weakly.
"And if I refuse?"
Kael's eyes turned cold.
"Then I'll leave you alive for them."
Reth's smile vanished.
Kael understood he had him.
The captain was brave when he thought he had control. But once fear entered, he would break.
Another crash came from above.
The hidden room door at the top of the stairway had been forced open.
Voices shouted. Men were coming down.
Owen grabbed the black crystal fragment that Kael had left on the chest and shouted, "Lucas, what do we do?"
Kael looked around the room.
There was the open chest.
The papers.
The key.
The chest itself.
Then he noticed the back wall.
One stone looked newer than the others.
His eyes narrowed.
He walked to it and pressed his hand against the stone.
It shifted slightly.
A hidden panel.
Owen rushed over. "There's another passage?"
Kael nodded once.
Reth's eyes widened.
"No—don't touch that—"
Kael looked at him.
"You know what is behind it."
Reth shut his mouth.
Kael's suspicion deepened.
He pressed harder.
The stone wall slid inward with a grinding sound, revealing a narrow dark tunnel beyond.
Cold air rushed out.
The system flashed once more.
[Hidden path detected.]
[Path leads deeper into restricted grounds.]
[Opportunity for escape and discovery.]
Kael's eyes sharpened.
This was not just an exit.
It was another secret.
Maybe even the real one.
The footsteps behind them were now inside the room.
Guards poured down the stairs, weapons raised.
Reth suddenly shouted, "He has the papers! Don't let him leave!"
Kael did not hesitate.
He shoved Reth aside, grabbed Owen's arm, and threw the papers into the boy's hands.
"Hold these."
Owen caught them quickly.
"What are you doing?"
Kael looked at the dark tunnel, then at the approaching guards.
His answer was simple.
"Surviving."
Then he ran into the hidden passage with Owen behind him.
The stone panel began to close behind them as the guards shouted in anger.
One of them tried to force it open, but the wall sealed shut with a heavy final sound.
Darkness swallowed the passage.
Owen's breathing was loud beside him.
"Lucas," he whispered, "what was that place?"
Kael kept moving.
He could not see far, but his new sense of the dark helped him enough to avoid the walls.
"It was the start," he said.
"The start of what?"
Kael did not answer right away.
He thought about the papers.
About the crystal.
About the names hidden in the records.
About Lord Varian.
About the betrayal that had already spread beyond one servant's death.
Finally, he said, "The start of the truth."
Owen fell silent.
They ran deeper into the tunnel, guided by the weak light of the crystal fragment in Owen's hand.
After a while, the passage opened into a wider space.
Kael stopped.
It looked like an underground chamber, older than the estate above it. The walls were carved stone. Strange markings covered them. In the center of the room stood a pedestal with a circular groove in the middle.
Kael frowned.
The groove was the same shape as the key from the chest.
He took the key out slowly and looked at it.
Then at the pedestal.
Then back at the key again.
Owen swallowed.
"Lucas… I don't like this place."
Kael understood him.
He did not like it either.
But the system reacted before he could speak.
[Key item detected.]
[Ancient seal nearby.]
[Unlocking may lead to rare reward.]
Kael stared at the pedestal.
Rare reward.
That was not all.
His instincts told him this chamber was important. Very important.
He inserted the key into the groove.
A click echoed through the room.
Then the pedestal began to glow.
And somewhere deep below them, something moved in the darkness.
