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

Slash!

A head was smoothly severed from its neck and droppd to the ground with a thump. It was a successful surprise attack. The Oni couldn't even defend itself as it's already too late by the time it noticed her in the back. If she had been any later, or the attack missed, the Oni might have screamed out to call the other the nearby monsters. 

『 Level 38 Oni has been slain! 』

After collecting the dropped item from the dead monster, she swiftly disappeared into the shadow to search for another prey. It seems an Oni was a rare monster as she couldn't find another one, so she instead targeted a group of Orcs currently fighting with three fierce wolfs. It isn't strange that she saw them fighting as in the end, they aren't from the same monster ideology, the Orc and Fierce Wolf. They aren't united under the same banner even if they are created by the system.

Though there's only three fierce wolfs against a small group of Orcs, which was 3 against 5, they aren't to be underestimated. When the Orc attacked, the Fierce Wolf systematically moved to the side before one of them took a huge bite of their meat as a payback. The Fierce Wolf aren't just known for their fierceness, they also works better in a group. Against the Orc, unless they are completely surrounded, they can still put up a good fight as they are undoubtedly faster than the Orc.

Nonetheless, the small group of Orcs isn't going down without a fight either. They are also quite resilient, even after losing some chunk of meat, their attack is still as strong as ever. 

Sheila wanted to join the fight so badly, but learning from her past mistakes, she somehow managed to control herself from recklessly jumping into the battle. She wasn't just simply watching them fights, she also took a careful look at her surrounding in case some other rare monsters decided to join the fight. A single Oni was enough to obliterated every one of them, she knew it firsthand even though she easily severed it's head a while ago. The aura around the an Oni isn't so simple, if she didn't took it down by surprise, she wouldn't have won so easily.

Just as expected, the noises from the fight brought the other monsters closer, but unlike what she thought, they didn't join the fight and instead choose to stay put. It was a strange feeling watching them hiding in a bushes. She feels like the monsters also thought of taking advantage of the situation by watching them exhausting their strength, and only when the winner is decided, they would definitely attack at that time, just like her.

Is it just her imagination or they appeared more intelligent than the previous monsters she had slain? If it was the monsters from the previous floors, they would have rushed straight into the battlefield as if they had no control of their mind. Perhaps the monster in the higher floors would eventually be able to have a conversation with her? That's something to look forward to, she thought before slowly creeping closer as the battle was about to reach the end. 

The monsters hiding in the bushes were also clearly ready to launch a surprise attack as they can also senses the Orcs and Fierce Wolfs had almost exhaust their strength. It was faint, but she can smell their leaked bloodlust from her location. If she's being careful, she would have left by now.

However, there's no way she would let them steal her prey! She had been here first, they have to go through her if they ever dream of kill-stealing in front of her. With that in mind, she quickly send a simple command directly to the mind of soldier giant ants hidden within the ground. She's telling them to be prepared to buy enough time for her to finish the battle. If it all works out, she will retreat safely.

After the long and torturous battle, it's finally coming to an end. Among the three Fierce Wolfs, two were severely injured and the last one seems to be having a breathing problem. As for the Orcs, one was unfortunately slain as it was the weakest of the bunch. The other four looks just as unfortunate as they already lost a huge chunk of their meat, especially on their arms and thighs. The leader of the orc even lost an arm. If it wasn't for their sturdy body, they would have long perished.

Just as the Fierce Wolfs was about launch their final and desperate attacks against the Orcs, a group of giant ants suddenly crawled out of the ground before assaulting the monsters hidden in the bushes. The exhausted and injured orcs and fierce wolfs alike were surprised at the sudden appearance of these monsters. They were too focused on their fight that they didn't notice their surrounding, and now that's too late, they are already so weakened that they can't run away even if they wanted to.

As expected, one of the four orcs suddenly got its head severed from the neck. When they all turned around, they could only see a thin streak of smoke disappearing into the shadow after successfully landing a killing blow. 

『 Level 37 Orc has been slain! 』

*GROOOAAAAAR!*

The leader of the Orc suddenly cried out once it realized it was surrounded by enemies on all sides with nowhere else to retreat. One of them was even killed before any of them could regain their clarity. Since there's no way for it survive through this battle, it might as well take the enemies with it straight to hell! 

With a strong determination, the leader of the orc might be missing an arm, but he could still be a frightening monster now that he was forced into a corner. Though, before he could give command to his dumb subordinates, he instinctually twisted his body around and luckily survived from being one shot by hair-breadth. He doesn't even know where such a small attack came from!

"Darn, the bullet missed even at such a close range," A high-pitched voice suddenly spoke with a hint of irritant from his shadow. The orc quickly grabbed his subordinates standing blankly next to him and use him as a shield when another gunshots exploded. 

『 Level 35 Orc has been slain! 』

"Huh, so they are just meat shields to you? That makes it easy for me~" a humanoid figure dressed in all black suddenly appeared out of the shadow. She was none other than Sheila. Once there's only two injured orcs left, she finally decided to come out of her hiding. 

When she decided to fight the orcs head-on, Sheila had already summoned Raksha and let the latter handles the exhausted Fierce Wolfs.

Although they might have comes from the same races, after being tamed by Sheila and named, it was then Raksha had severed herself from her own kind. Though her race remained as Fierce Wolf, she is completely different on the inside. Her potential is no longer restricted by her race anymore, it is now limitless. 

Awoooo!
