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

"I'm Shiro, the guy who will torture you to death for killing the students without any solid reason. I hope you're prepared for it as I don't want to accidentally kill you or something."

After introducing herself, Sheila immediately sent the man flying once again with a swift kick toward his neck by twisting her body, stopping him from saying something to her. On the way here, she managed to distract the other students by baiting them toward another way so that they won't cam across this mad man. By disguising herself as one of the male students, she secretly summoned Phoenix before commanding it to flew above the school premise. A few minutes later, she(in this case, he) stood closer to the window from the opposite of the hallway toward the man and shouted. 

"Look! Is that a real-life Phoenix?!"

With just a shout, it quickly brought the students' attention as they went next to her before stretching their neck to look out of the window despite the doubt on their faces. The moment they looked outside of the window, they were left dumbfounded, all doubts they had on her disappeared soon after as if burnt to the crisp by the Phoenix itself. 

"That is...a real Phoenix!"

"Unbelievable..."

"It's just a burning chicken though, what is so interesting about it?"

"You, come here. I'll show the greatness of the Phoenix in detail."

"Don't worry, we won't hurt you."

"Wait! I was just joking! I—"

Ignoring that one student asking for help while being dragged away by two other students, Sheila quickly left the scene after she had accomplished her mission in baiting the other from the hallway. If she hadn't done this purely out of goodwill, there might be a lot of deaths. Honestly, Sheila didn't really care much about others, however, if she can prevent meaningless death with her own power, then she would. It would leave a bad after taste if she chose to ignore what's happening in front of her eyes, after all.

Though currently the students were distracted by Phoenix, she needs to finish this soon, or they might get here before that. 

"So, you are the one who caused a mess in the branch of Mage Association! Heh, Lucky me. I don't care much about what those higher up think and do but, if I can catch you alive and give it to them, sure as hell I'd get a good promotion."

"You? That's rich, give it a try then. Let's see if you can catch me, or will I end up killing you first, whichever it is?"

"I'll show you alright, look and behold, this is the power that would bring you down to your knees!"

Along with his loud exclamation, the small gem on his forehead started to shines even brighter than before. Clearly more evident than his previous transformation, the man's body started getting bigger and bigger along with his overall size, it only stopped until his shirt rip to shreds by the bulging hard muscle. It wasn't just his body that has changed, heck, his aura has also gotten even more terrifying and domineering. If the previous him is that of a bear, the current him would be an experienced hunter of a lion.

The boy, Luke, was visibly affected by it as his legs turned wobble as he felt down to the ground on his butt with his face paled as one can get. Sheila easily shrugged it off as if it was nothing. No matter how one looked at it, the gem did boost him with strength. Perhaps, she might pluck the gem out of his forehead just to analyze what kind of sorcery and rules on how it works. 

"Hahahaha! Behold, this is my full strength! I can feel it! I can feel my body pulsating with a terrifying strength! With my current state, I am Undefeatable!"

Nevertheless, though his aura couldn't affect her, she still needs to be careful around him as his strength at the moment would definitely give a run for her money. If she were to estimate it based on her feeling, he would most likely be around level 40, which is a level higher than the current her. Most importantly, if all his attribute points were invested in strength only, then he is undoubtedly stronger than her, who distributed it all over the place for a reason of wanting to have a balanced character.

"Hmm, you are indeed stronger than me now, strength-wise."

"Of course! So, are you going to give up now? I won't mind if you lick my shoe and ask for forgiveness, and perhaps, I might consider not injuring you. You will still have to follow me though, Gahahaha!"

The man laughs unrestrainedly as if the deal is already in his hand. If it had been someone with a sharp sense, they would have noticed the importance in her words and stays cautious around her, but thankfully this man is an idiot. Indeed, the man's strength might be higher than hers, but that doesn't mean she would lose. 

Raw strength is not all there is in real combat. One must not forget about skills and experiences. Even if one has weak strength, they could still beat people stronger than them if their skill in combat is much more formidable than their opponent. 

"Strong as you may be, I'm not even a tiny bit afraid of you. Come, show me what you got."

Sheila indifferently said with a provoking gesture from her hand. Looking at the masked guy's indifferent attitude toward those terrifying aura, Luke was left dumbfounded. As ignorant as he is, if he has to compared between the two of them, the man seemed more terrifying than the masked guy for an obvious reason. That was what his logical side of reason telling him, but somehow, a part of him said otherwise. Since the masked guy clearly wasn't as affected as him, and their previous demonstration of strength, they must have a way to defeat the man who was more like a demon now.

"Hmph, I guess I have to beat you up to submission if that is what it takes to make you give up, I am more than willing."

As if the man 'blink' out of existence, he promptly disappeared from his previous location before appearing right behind the masked guy. Sheila was surprised, it wasn't just his strength that increased? With that thought in mind, she was thus sent flying by a powerful punch straight to her back. 

*Bam!*

"Hahahaha! I told you, with my current strength, I am Undefeatable!"

Within a broken wall of debris, a figure stood up from the ground while dusting off the dust of their clothes. 'So that's some of the power of someone who prioritizes on strength at level 40, huh? It hurts like hell. I think a few of my ribs are broken, god, why did I decide to let him hit me when I can easily avoid it? If he had used all his might, there might be a hole in my body by now. What was in the brazen hell am I thinking? Is the damn curiosity taking over me again? it must be that darn curiosity!'

'Well, I can't help it alright? I simply wanted to know how strong the punch would be, not expecting it to be THAT strong. I must have gotten so brazen these past few weeks mostly because I have potions with me all the time. Thankfully, the savior title took effect since technically, I'm protecting that boy over there. Alright, I also need to get serious.' thought Sheila yet her expression remained stoic even with the mask covering half of her face. Even if she's hurt, she would never show it to her opponent for them to exploit.

"Is that all?" Sheila said with a tone devoid of any emotion, yet her internal thought was, 'That flipping hurt, you bastard! How dare you gone beyond my expectations when you are just a mob! Just you wait, I'll get my revenge!'

When the man 'blink' once again, she immediately twist her body and managed to avoid his punch before sending a swift kick at him as a counter, in which he was able to defend it with both of his arms held up in front of his face. Although the damage he got was minimal as much as little numbness on his arms, it still managed to send him a few steps away from her. Even Sheila had to admit that his arm is as tough as hell.

"It's futile. Your strength couldn't possibly harm me in my current state."

Sheila nodded her head in agreement with his words. If neither punch and kick work, how about a weapon then? With that thought in her mind, she swiftly entered her shadow which surprised the man. A few seconds passed, just as he thought she had run away, she silently appears right behind him before smoothly swinging her sword horizontally toward his neck. 'A sword?! Where did it come from?!' thought the man as he intuitively leaned over, saving his neck from separating itself from his body.

"How about now? No matter how tough your body has become, could it still withstand against a real blade?"

She said after putting a distance from the man with her sword faced straight toward him. 

"Tsk, you think I'd be scared with that fake sword of yours?!"

"Then come at me, we will put it to test whether the sword in my hand is real or not by cutting you to pieces."

The man quickly went quiet. Although he had never seen a real sword in his entire life, after all, it is an ancient weapon in comparison to the modern age where gun and nuclear alike, is the hottest weapon of all time, yet he could somehow tell that the sword in the hand of the masked guy is certainly real. 'Do I have no choice but to went beyond my limit? I have been warned not to do it under any circumstances, but with my current predicament, there's no other choice other than that.' 

"GROOOAAARR!"

'What? Can he still strengthen himself even more than now with that gem in his forehead? This isn't good. I have to end it now, once and for all before things get dangerous for me.' thought Sheila as she throws her sword aside and immediately will it in her mind for the burning spear to appear by her side.

『 Vanquisher, Ravager of the Burning Sun! 』

The moment the spear appeared, she quickly grasps it into her hand before positioning herself for her next move. As the man's body started to enlarge once again brim with power, Sheila took a couple of deep breathes before throwing the spear in her hand with all her might, straight toward the man.

*Swoosh!*

*STAB!*

"Gah! I...I didn't...even finish tran...yet.."

"Sorry, but I won't stand there like an idiot and let the chance to kill you go just like that."

With the burning spear effortlessly penetrate through his body, the man was left with a gaping hole at the size of a ball at the center of his chest. Without having a powerful regeneration like a certain vampire, the man soon succumbed to his death without being able to finish saying his last words. Following his death, the gem on his forehead appears to have a crack in it before finally shattering to pieces.
