I didn't remind Lio that it was my birthday.
I left the house alone.
Not because I wanted to avoid them—but because there was something I needed to do first. Something far more important than celebrations, breakfast, or even the system messages still lingering at the edge of my vision.
I needed to test it.
As I walked through the town, I activated the system function that had been quietly waiting since morning.
Treasure Sense.
The world didn't change visually—not at first. But then faint indicators began appearing in my peripheral vision, subtle pulses of awareness rather than bright lights.
Iron-rank treasure detected.
Distance: 14m.
I paused near a dockside warehouse and focused.
A small panel expanded.
[Treasure Detected — Iron Rank]
Type: Coin Cache
Origin: Sailor-owned
History: Hidden by a deckhand before departing on a voyage five years ago.
The sailor never returned.
The location of this cache was never passed on to his family.
I closed the panel slowly.
There were more like it.
A rusted dagger beneath a loose floorboard.
A sealed bottle with foreign markings buried near a pier post.
Old coins wedged between stones.
Most of them shared the same story.
People who left. People who never came back. Treasures forgotten—not because they lacked value, but because no one remained to remember them.
I didn't take any of them.
Not yet.
I kept walking.
Eventually, my steps carried me toward the eastern side of the island—where cliffs rose sharply from the sea. This part of the island was quieter, shielded by my mother's illusion field. The ocean here appeared calm, almost unnaturally so.
Safe.
As I neared the edge, the system reacted again.
Stronger.
Heavier.
Treasure detected.
I froze.
Distance: 70 meters.
Depth: Below surface.
And then—
Rank: Bronze.
My breath caught.
Bronze was the highest tier my current Treasure Sense could detect.
I stepped closer to the cliff's edge and looked down.
The sea below was a deep, tranquil blue. Sunlight scattered across the surface, revealing nothing unusual. No wreckage. No debris. No signs of danger.
But the system didn't lie.
I summoned the panel.
[Treasure: Maren Shipwreck]
Rank: Bronze
Type: Lost Chest
Origin: Maren Family Expedition Vessel
Status: Partial Recovery
History:A Maren family ship returning from an early expedition encountered violent underwater currents during a storm.
Most of the cargo was recovered.
One chest was lost.
Underwater currents carried the chest into a submerged cave along the eastern cliff face.
The chest has remained sealed and undisturbed.
My chest tightened.
Maren… family ship.
The words echoed in my mind.
And suddenly, I remembered.
A story my grandfather used to tell me when I was little—late at night, when the oil lamps burned low and the sea outside roared against the shore.
A tale of his youth.
Of a storm that came out of nowhere.
Of a ship nearly torn apart by unseen currents.
Of a single chest swept away before anyone could secure it.
At the time, I'd thought it was just another sailor's exaggeration.
Now I knew better.
I stared at the calm water below.
Seventy meters down. An underwater cave. A chest that had waited decades—forgotten by time, but not by the sea.
And it was safe.
Mother's illusion field ensured no sea beasts patrolled this stretch of water. No predators. No lurking horrors.
The ocean itself had protected it.
Or perhaps… preserved it.
My pulse quickened.
This wasn't just my first treasure.
It was a Maren treasure.
A fragment of my family's past.
And the system had led me straight to it.
I stepped back from the edge, already planning.
Breathing steady. Mind sharp.
The hunt had begun.
I ran.
Straight toward the cliff's edge.
For a heartbeat, the world vanished beneath my feet—and then I leapt.
Like one of those old Earth games I barely remembered now, an assassin's leap of faith, body streamlined, arms tucked, mind empty.
The ocean rushed up to meet me.
WHAM.
Cold swallowed everything.
Forty meters down.
I'd done this jump before. Many times. The first time when I was ten—on a dare, stupid and fearless. I still remembered Mother nearly fainting when she found out.
I kicked, angled my body, and let the current guide me deeper.
The moment my head dipped beneath the surface, the system responded.
A faint marker appeared in my vision—an arrow, subtle but unmistakable.
Treasure location highlighted.
Good.
I swam in that direction, lungs burning slowly, counting my strokes. When the pressure became too much, I surfaced, drew in a breath, and dove again.
Once. Twice. Again.
On the nth dive—when my muscles were beginning to ache and my vision edged with white—I saw it.
Vines.
Thick, sea-darkened vines clinging unnaturally to the cliff face.
I pushed them aside.
Behind them—
A cave.
Hidden. Natural. Thirty meters deep.
I slipped inside.
The water grew calmer almost instantly, and a moment later I broke the surface, gasping as I emerged into a pocket of air.
An air bubble—large enough to stand in.
I rested my hands on the cave wall, breathing hard, water dripping from my hair and clothes.
"…Found you," I whispered.
I took a few steps forward.
And there it was.
A chest.
Wood reinforced with aged bronze bands, untouched by rot, sitting quietly where the sea had carried it and then forgotten it.
My heart thudded.
This was it.
The Maren shipwreck's final secret.
I was about to approach when something else caught my eye.
In the far corner of the cave—half-buried beneath stone and mineral growth—something gleamed.
Not bronze.
Something brighter.
I took a step toward it.
DING.
The sound echoed not in the cave—but in my soul.
A system message exploded into view.
[Congratulations! You have discovered a treasure beyond your detection limit using your own effort. Treasure Classification: GOLD]
[Achievement Recognized: Independent Discovery]
[Treasure Sense — UPGRADE COMPLETE]
You can now detect Silver-grade treasures.
Detection clarity and range slightly increased.
I froze.
"…Gold?"
My breath hitched.
I hadn't even been able to sense gold treasures until seconds ago.
And yet—I had found one.
Not because the system told me to. Not because it guided me.
But because I explored.
Because I trusted instinct, memory, and the sea.
The glow in the corner pulsed softly now, no longer hidden.
My hands trembled—not from exhaustion this time, but from realization.
This was it.
The moment everything shifted.
The first treasure wasn't just found.
It was earned.
And the system had noticed.
