Humanity's Strongest Loser(dropped)

Chap. 1(The mysterious man)

...

I slowly open my eyes and yawn.

"What time is it?" I ask.
"12 PM, sir." Says the device in my hand.

2291 is advanced. Technology has stolen every single spotlight in this era. But towards the demons, even technology is worthless. Right now, magic and strength dominate everything.

"It's like we are some sort of animal living in the jungle..." I mumble.

Yes, this world is now a dog eat dog world. The jungle's law applies to everywhere now.

Mother nature is thriving due to the current population. 10 years have passed since the beginning of the invasion, my original hometown is now covered in algae and different plants. Of course, in the ruins state.

Right now, I just live in the forest and continue to train every single day. It was very harsh at first I assure you...but...my sister kept me going.

Ah...i wonder how she looks like now. I have heard rumours from passing by merchants about her. Something about her being the top four pillars of humanity.

I jump off the tall tree I was sleeping in and yawn once more. Scratching my head, I decided to do my daily routines of work out.

5000 sit-up
5000 push up
10000 swings of the sword
10000 punches
100km of jogging around the mountain.

That's my limit for now. If I can, I will increase it once I can finally do more.

!!!

On my 3198th sit-up, I detected some presence. 2 big figures and a small figure.

"Heh. This elf is going to sell for a good price." One of them says.
"Hey! Don't ruin the quality of our product!"
"Come on! It's fine...as long as nobody tells anyone."

Hmm...

I smirk and sighs.

I guess I can skip my daily routine for today.

"Mph!!! Mmm!!!"
"Stop struggling-"

The car suddenly halts, jerking the man at the back.
"Hey! Why did you stop all of a sudden?!"
"Uh...someone is blocking the road." Says the driver.

He becomes irritated and slams the door open.
"Hey! Get off the road! We have some quick business to attend to!"

"Hmm? What business?" I ask.

"You! That's it! Don't say I never warn you."

He unsheathes a dagger and dashes at me.

This man...is using mana energy and infusing it into his dagger.

Woah...nice.

But, it's completely useless against me.

He thrusts the dagger aiming for my chest but upon impact, the blade breaks.

"Wha-"

With the momentum from the dash, I kneed him in the groin.
"Arghhhh!!!!!"

Haha! This guy squealed like a girl!

"You...You bastard!" He says, getting up.
"You will regret-"

I didn't let him finish his sentence and punched his face. It pissed me off.
He was flung to the car and completely trashed the entire front part.

I didn't even use 10% of my strength on that punch...what??

"You...who the hell are you?" Says the man.

"... I'm... Ushio Yuuto. I'm a Japanese and yes, I do speak English."

The man eyes widen once he hears that.
"I-I'm so sorry!!! My eyes were blind to recognise you!"

"What?"

"You are her brother, right? Ushio Yukino's."

My eyes widen and I laugh.
"Haha!! What a small world, yes I am, why?"
"S-She is currently the world most powerful fighter against the demons. As expected of her brother, you were not even using your full strength and it's already this devastating."

Oh...he realised.

"Then bring me to her," I say.
"But...i heard she's in Yilim right now and it's quite far. We will have to pass through Selcam and-"
"Then be my escort, if you do, I will reward you heavily."

He smiles when he hears that and agreed.

"Oh yeah, that elf little girl, let her go. She will be a hassle."
"Oh...uh...okay."

I look at the car and pulls the driver out.
Using the atmosphere mana, I channel into my fingertips and silently cast a time reverse spell, making it to the way it was before.

Now then...it's finally time to leave the forest. That bastard, black hair, blue eyes, a scar on his left eye, a mole on his right index finger and roughly the size of an average muscular man...
The bastard who killed my parents...
Wait for me patiently.

I WILL PERSONALLY DETACH EVERY SINGLE ONE OF YOUR LIMBS AND FINALLY, CRUSH YOUR HEAD UNDER MY FEET...just like how you kill my father and mother.
