The World seems Realistic but Why do I have a Leveling System?

In a busy street, one could sense panic-stricken on everyone's faces no matter the age or social status, they all hurriedly ran away as if afraid the longer they stay behind, the more likely they will lose their life. Two high school students couldn't even step into the internet cafe before they were pushed out by the people running out of the building. The moment they feel a small vibration from the ground, the two immediately turned their head toward the opposite of the people running away and was dumbfounded by what they had witnessed.

Thump!

"Run! Kyaaa!"

"My child! Have you seen my child?!"

"Get the hell away from me!"

Thump!

"Oh, God..."

"What...the hell."

Thump!

"Is that..."

"Don't you dare say it!"

"...a fucking Godzilla?!"

"Damn it, dude! Anyway, stop joking around, let's run!"

Even from afar one can tell at a glance that the thing on its way here was massive. And all that witnessed it was struck by fear and feeling incomprehensible as if they couldn't believe what they were seeing. After all, their common sense never says anything about an existent like the huge lizard spewing flame one after another—clearly mad by thrashing around the surrounding as if someone had murdered its entire family or something.

Thump!

"What the hell. I thought this is a world of logic and science, then what am I seeing right now?" Carl muttered in disbelief with his mouth wide open. It was such a lovely day with the sun burning brightly up in the sky. He was on his way to the internet cafe to play a game or two with his friend, everything was normal back then, but just as they reached the front of the premises, they felt a sudden vibration from the ground like that of an earthquake. It was a small one, and that alone couldn't have made everyone lost their mind immediately.

That was until their sight caught onto the glimpse of 'something' moving from a distance that frightened them to their death. Everything on its path, all of them were blazed to the ground leaving nothing but blackened ashes and dirt. The only thing the people can do was to run away, and they did exactly that which brought the current pandemonium happening all over the area. Those unable to run stricken by fear can be seen despairing on the street with their face full of snorts.

Even Carl who had seen worse things happen to people on the dark side of the internet couldn't help but be stunned. This is a real-life dragon we're talking about! One might call it Godzilla, even. No matter how he looked at it, it's without a doubt a real dragon breathe fire.

'Did I just get isekai-ed? No, the building around me is still that of modern-era building, which definitely didn't give off medieval time at all.' Carl concluded with a wry smile on his face. That means a real dragon actually exists, he wasn't delusional. Looking at the rampaging dragon growing bigger the shorter the distance, he could feel his peaceful life breaking down to pieces in his mind.

"No, this isn't the time to be thinking about that." He shakes his head before turning to the side, and unsurprising, his friend was also dumbfounded. He tapped the latter on the shoulders to bring him back to his sense before saying, "Stop daydreaming, we're also running away."

But before they could turn tail and run away, they saw an alarming ball of flame heading speedily toward their location. Even if he stepped or roll to the side, the explosion will likely still injured him in some way or another; Carl realized he and his friend can't get out of it unscathed. Gripping his fist tightly, he quickly stood in front of his friend with a determined look on his face as he guards his front with both of his arms. Just as he thought the fireball would hit him and send him flying, a shadow passed by him, and he then saw a figure calmly floats in the air ahead of him.

Judging by the long black hair, Carl assumed the figure is a female. When the figure turned her head to glance at him, he noticed there was a white mask equipped on her face. 'What a shame,' he couldn't help but think of that. The way she carried herself suggests there may be a beautiful face hiding behind the mask. But when his gaze arrived on her chest, he was disappointed to see it was as flat as a wall. Maybe it's a guy?

Perhaps she can read his thought as he could feel a piercing gaze on him, so he immediately looks away with sweats on his back. Though it feels like time passed longer during the time he was admiring the person floating in the air, in reality, it has only been a few short seconds. By the time he turned around, he was amazed to see her easily deflecting the fireball with the back of her hand up to the sky.

Carl no longer questions how the person was floating in the air, or how she easily stopped the attack that would most likely kill him, the moment he saw the rampaging dragon. The only thought he has at the moment was, can he also become someone like her? Someone who manipulate unseen force that can make one float in the air, and a body that strong enough to deflect a ball of flame without receiving any burned wounds whatsoever.

Even though the danger element is still rampaging and bringing destruction everywhere it goes, Carl couldn't help but imagine himself like a superhero in the movie. By the time he comes to his sense, his savior has already flown toward the dragon while saving people on her way there. At that moment, he could see a figure of his imaginary superhero overlapping with his savior in his mind.

It was righteously beautiful and deeply imprinted in his mind from then onward.
