Now enjoy,

My name is Luke Masters and right now I'm lying in a ditch fighting for my life,

The reason, it's because I'm a talentless failure,

My brother, a bigger boy with the talent of a fighter; has beaten me within an inch of my life.

'I must- no; I will survive,' I thought to myself,
Just then a mechanical voice spoke in my head,

{ Host has met the requirements; you are now the master of the job class system,}
{Speak your name player,}
" Luke Masters," I said
{ Luke Masters pick a starter class,}
There were five starter classes,
{Swordsman,}
{Arbalast,}
{Fighter,}
{Healer,}
{Mage,}
'Right now I don't have a sword; I don't think healing will be useful at the moment; magic requires a range to work, and a six-year-old with a gun is a bad idea.' I thought to myself.
" I choose a fighter," I said.
{ Player has achieved fighter class;} said the system.
{ Player has learned four new skills;}
{ Power punch, Cyclone Straight, Dragon Kick, Ball Buster,}
' Ball Buster?' I thought.
"I'll try it out," I said.
As my brother laughed I stood up.
" Hey big guy; let's try that again," I said.
My brother turned around laughing.
" So...you think you're tough eh; fine then, I'll show you what tough guys are really like," said my elder brother Richard.
He took up a boxing stance and came at me,
{ Engaging battle mode,} the system said.
I felt a surge of power come over me with the knowledge of my skills,
" Let's dance bro," I said with a new-found air of confidence.
He came at me with a swaying hook punch, but either he was too slow, or maybe I was too fast, as it looked like he was in slow motion,
{ Choose a skill,} said the system.
" Ball Buster," I said,
and suddenly I span around lifting my leg  out landing a heel kick to the crown jewels of my 'precious' older brother,
" Nagh,ah-ah-ah," he cried as he covered his balls.
{ Choose a skill,} said the system.
" Cyclone Straight!," I shouted
As I faced my opponent, a fierce determination surged through me. I could feel the adrenaline pumping through my veins as I focused on my next move. knowing that this was my chance to strike. With a quick motion, I cocked my left arm back and then unleashed a powerful left punch that felt like it could take down a wall.
The force of my blow was so intense that it created a massive vacuum blast, sending a gust of wind blasting into my opponent. I stood there, my heart racing, feeling the rush of excitement that came from knowing I had just executed the finishing move.

After my attack hit him it launched Richard into the air, and then a moment later My 'precious' brother fell from the sky covered in bruises from the powerful attack.
" ...how...you...were...a.... talentless...loser," he said and passed out,
{ Objective completed: get revenge on Richard} came a notification.
{ Reward twenty skill points,} the system chimed
{ Allocate skill points to status,} said the system.
{ Status}
{ Strength Lvl 7}
{ Speed lvl 5}
{ Stamina lvl 7}
{ Agility Lvl 5}
{ Endurance Lvl 7}
I decided to add 4 points to each stat for a balanced build,
So now my stats were Strength 11, Speed 9, Stamina 11, Agility 9, Endurance 11,
After which the system chimed.
{ You have increased your base status and as a result, you have been rewarded with a fighting scroll,}
' A fighting scroll,' I thought to myself,
