The moment I said the words...
"Start Tutorial."
The world disappeared.
Everything around me turned white.
It felt like I was being pulled through space itself.
A second later, my feet touched solid ground.
I looked around.
Nothing.
Just endless white in every direction.
"...This looks exactly like the Hyperbolic Time Chamber from Dragon Ball."
Rex's voice echoed around me.
"Welcome to the Tutorial Dimension."
"Time flows differently here."
"You may spend days training while only minutes pass outside."
"That's... actually awesome."
The empty world suddenly began to shake.
Stone walls erupted from the ground.
Mountains formed in the distance.
Targets appeared.
Training dummies armed with swords rose from the floor.
Within seconds...
An entire battlefield had been created.
"Before we begin," Rex said, "you must understand the rules of System World."
Images appeared in the air.
Humans.
Elves.
Dwarves.
Beastmen.
Demons.
Monsters.
Dragons.
"There are countless races," Rex explained.
"Everyone possesses a System."
"Everyone can become stronger."
"Everyone can die."
The images changed.
Cities burned.
Kingdoms fell.
Monsters devoured entire armies.
"There is only one law that every world follows."
Kill... or be killed.
I swallowed.
"So there's no peace?"
"There is."
"...For the strong."
Rex continued.
"You will receive your Class at Level 12."
"A Class greatly increases your strength and unlocks new paths of evolution."
"So I have to reach Level 12 first."
"Correct."
"How?"
"The old-fashioned way."
"Training."
"Combat."
"Quests."
"Survival."
Suddenly...
Twenty armored soldiers appeared around me.
"Your first lesson."
"Hand-to-hand combat."
The first dummy charged.
I smiled.
"Come on."
It punched me square in the face.
I flew backward.
"...Okay."
"That hurt."
Rex spoke without sympathy.
"Again."
For the next two hours...
I was beaten.
Again.
And again.
And again.
Every mistake earned another punch.
Every successful dodge earned another lesson.
Eventually...
Something clicked.
The next dummy attacked.
I slipped to the side.
Dodged.
Countered.
One punch.
Two punches.
Three.
Four.
The attacks flowed together naturally.
DING!
Trait Activated
Attack Chain
Consecutive attacks become faster and more powerful.
I blinked.
"Seriously?"
"So combos are actually a thing?"
"Yes," Rex replied.
"Attack Chains exist throughout System World."
"They may be purchased from special shops."
"Wait..."
"People can BUY this?"
"They can."
"Then how did I unlock it for free?"
There was a brief silence.
"Humans often develop abilities through repeated practice."
"It is... unusual."
"Our creators wished to observe your species."
"Our creators?"
"The gods."
"They reincarnated you out of curiosity."
"They wish to see how humans adapt to this world."
I laughed.
"So I'm basically an experiment."
"You could say that."
The training continued.
Sword drills.
Knife fighting.
Gun handling.
My eyes widened.
"There are guns here?"
"Yes."
"Our creators admired your world's technology."
I couldn't help but grin.
"Good."
"I was one of the best marksmen in my unit."
Hours passed.
My body ached.
Sweat poured down my face.
Even inside this strange dimension, exhaustion felt real.
I dropped to the ground.
"What's next?"
"One thousand push-ups."
"...Seriously?"
"Nine hundred ninety-nine remain."
I sighed.
"This world is trying to kill me."
"No."
"It is trying to strengthen you."
By the end of the day...
Every muscle in my body burned.
Yet...
I felt stronger.
Faster.
Sharper.
My senses had completely changed.
Rex had taught me how to hear movement, read breathing, and predict attacks before they happened.
Then...
A blue screen appeared before me.

I couldn't stop smiling.
"A real status window..."
"This is insane."
"There is one more lesson," Rex said.
"There are three categories of Systems."
"Common."
"Rare."
"Legendary."
"Some Systems may evolve."
"Others cannot."
"Evolution depends upon compatibility with their Master."
I nodded.
Then another question crossed my mind.
"Rex..."
"Do you have a real name?"
A long silence followed.
"...I once did."
"It was forgotten over the ages."
"I have existed for over one billion years."
"I no longer remember what I was called."
For the first time...
Rex sounded lonely.
"So I can give you one?"
"Yes."
"If my Master names me..."
"Our bond will deepen."
"My power may increase."
"What should I call you?"
I thought for a moment.
Then smiled.
"You always seem calm."
"Strong."
"Reliable."
"So from today on..."
"Your name is..."
"Rex."
Everything froze.
Golden light erupted across the Tutorial Dimension.

Rex sounded happy.
"It is now time to choose your first two skills."
A new screen appeared.

Punch
Kick
Taunt
Mage Skills
Heal
Air Missile
Fire Missile
"You may choose only two."
I rubbed my chin.
"Punch would make me stronger up close..."
"But Heal could save my life."
"And Fire Missile gives me ranged attacks."
"This isn't an easy choice..."
After several minutes, I finally nodded.
"I've decided."
"I choose..."
"Heal... and Fire Missile."
The two skills dissolved into streams of light before entering my body.
Warmth spread through every muscle.
Power surged through my veins.
DING!

Heal – Level 1
Fire Missile – Level 1
Before I could celebrate...
Every alarm inside the Tutorial Dimension began blaring.
WARNING!

First Quest Generated.

The white world around me began to collapse.
I took a deep breath.
"So..."
"The real adventure starts now."
A portal opened before me.
Without hesitation...
I stepped through.
