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

10 minutes ago before the tragedy, Herry, the leader of his gang was told to wait in the room next door with guns in their hands while his 'boss' brings another group of thugs that he hired inside the other room. Since he had done this type of 'business' a lot of times and all of them were a huge success, Herry is not worried about his boss and in fact, the man and his gang were drinking while discussing where they would spend the money earned for today. To them, the deal is already on the seal as no matter how 'fierce' the tiger is, a single or two bullets is enough to silence it for eternity.

When they heard the gunshots resound the room next to them, they just laughed and continue drinking to their heart content, some even thought of joining them the 'fun' but decides against it and resume drinking. While Herry was having an arm wrestle with one of his gang, the device next to him suddenly rang which brought all the attention to it.

"Hoh? It appears that this time, the tigress is pretty 'fierce'. Alright, y'all stop drinking and pick up your weapon. It's our time to have fun with another yet 'fierce' tigress!"

"OOOOH!"

But just when they were about to head out of the room, all of them come to a halt in one spot before one by one, they fall flat onto the floor. No matter how hard they tried to get on their feet with all their strength, none could actually move at all. Even Herry, the man who was known for his strength simply couldn't do anything and just stood on the spot, it feels like he was shouldering a heavy mountain on his back. It would be something if one of them could actually move in such a situation, but all of them are undoubtedly ordinary people.

"Ugh! What's going on here?!"

No matter how he thought about it, everything happened so suddenly and before he knows it, he was already caught frozen on the spot. But it was not just Herry who want to know the truth as everyone started inquiring each other with doubts in their face, believing that one of them was actually a betrayal that caused them to be caught in the trap. Just as things start to get heated up, Herry was about to shout and silence them only to get his face to flatten to the floor by an invisible force. Just as the man started to get riled up from anger, the door of their room was suddenly opened from the outside and a feminine figure steps inside the room.

"W-Who are you! Are you the one who did this?!"

"I certainly the one who did this to you all, well, let me take care of this first."

Sheila said with a nodded before moving on from a person to another, taking the guns from them and storing inside the inventory, but to others, it looks like the weapon disappeared when it got into her hands. Though the guns are useless when fighting an enemy that has a protection spell around them, it still can be used to either scare off ordinary people who tried to make trouble for her or maybe she could just sell it to the system's shop, either way, it will stay rot in the inventory for now. After Sheila was done unequip their weapons, they were finally able to move as Sheila has removed the restraint she put them through, it was a powerful restraint with the combination from Shadow Magic and Intimidation skill.

The moment Herry could move, he immediately unsheathed the knife in his jacket before sprinting towards Sheila like a cheetah hunting for its prey. Though his speed looks fast from his gang's perspective, if Sheila could see his status, his Agility stats would probably be around 10 or so which is quite high for a normal person. But Sheila's agility stats is even more monstrous than him, and with a minimum movement, Sheila easily evades the attacks before counterattacking with a kick of her own to his guts which send the man flying and crashed to the wall. His gang was also about to make a move by planning to surround Sheila, but when they saw their leader get his ass kicked just like that from those thin and weak legs of a girl, they immediately give up as those who were still laying on the floor went and did the same action like those hired thugs, which was playing dead.

But no matter how 'real' their act seems to be, Sheila only believes after she went through them one by one, and knocking them up by her own hands. Realizing even that didn't work against the ruthless girl, though they knew it was futile to fight against her, some still rush toward her as they didn't like the feeling of getting cornered by her. And while the stupid morons were rushing toward her, the remaining smart ones use the opportunity created by those and tried to escape by leaving the room, but when they reached near the door, their body was enveloped by the restraint created from Sheila. Basically, all of them were unable to escape their fate from getting one their limbs broken by Sheila, it took exactly ten minutes for her to finish the deal and by then, she could hear a knock on the door.

"Umm, Sheila? Are you done yet?"

"Ah yes, wait up."

When Sheila opened the door, she saw Yuna with a worried look on her face, perhaps because she couldn't hear anything from their room that she decides to leave the room with Ria. Sheila could already tell since she could sense their presence even while she was focusing on beating the mercenary to a pulp. Though Sheila knows that it's wrong, she couldn't help but feel great when beating a man that's many times bigger than herself. It was like the feeling of accomplishment when she had clear the boss in the game after staying up late at night. With a smile on her face, Sheila opened her mouth and said.

"Shall we head home?"
