Got it—now the system is clean, logical, and progressive. I'll write it in first-person narration + clear conclusion, exactly matching your rules.
When I reached home, nothing felt different.
Same broken door.
Same dim light.
Same quiet poverty.
But my eyes… weren't the same anymore.
I sat down slowly and summoned my spirit.
The door appeared behind me again.
Plain.
Silent.
Useless… if seen by others.
I stared at it without blinking.
Not with hope.
With calculation.
Analysis
I closed my eyes.
That strange stillness returned.
The world froze.
Thoughts became clearer… sharper.
And then—
The rules revealed themselves properly this time.
🚪 Core Ability: Travel
Before Level 10:
I have 2 opportunities
Each opportunity = 2 months stay
Total = 4 months
I opened my eyes slightly.
So that means…
Before even becoming a true Spirit Master—
I already gain extra time no one else has.
But that wasn't the important part.
📈 Growth Rule
I focused deeper.
The door trembled faintly… as if acknowledging my understanding.
More information surfaced.
Each time I gain a spirit ring (every 10 levels):
➡️ My total stay time increases by +4 months
I repeated it slowly.
"Level 10…"
"Total stay… 8 months…"
So after getting my first spirit ring:
Still 2 opportunities
But now total stay = 8 months
→ Each travel becomes 4 months
My breathing slowed.
"Level 20…"
"Total stay… 12 months…"
That means:
Each travel = 6 months
Final System (Fully Understood)
I laid it out clearly in my mind:
Before Level 10 → 4 months total (2+2)
Level 10 → 8 months total (4+4)
Level 20 → 12 months total (6+6)
Level 30 → 16 months total (8+8)
Level 40 → 20 months total
Level 50 → 24 months total
Level 60 → 28 months total
Level 70 → 32 months total
Level 80 → 36 months total
Level 90 → 40 months total
What This Means
No attack power.
No flashy ability.
No respect.
But something far more dangerous—
Consistent advantage.
While others train for 1 year…
I live more.
Learn more.
Survive more.
And the best part?
Time here…
Never moves.
Final Thought
I looked at the door one last time.
Still silent.
Still ordinary.
To others…
It's nothing.
But to me?
This isn't a useless spirit.
This is…
A slow, unstoppable path to superiority.
I stood up, expression calm.
"No need to rush…"
Because now, more than anyone else in this world—
I have time.
