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

『 Welcome to the Trial Tower! 』

『 The requirement has been met. 』

『 Do you wish to ascend to the Second Floor? 』

    『 Yes/No 』

"What?"

Sheila blankly stares at the notification in front of her right after she entered the Trial Tower. Second Floor? You mean this grassland filled with jelly creature bouncing off here and there is the First Floor then? And what do you even mean by 'the requirement has been met'?! I have just entered!

"Fuh~"

She took a mouthful of a deep breath to calm down her nerve. After calming herself, she begins to ponder what kind of 'requirement' she had met/done before entering the Trial Tower.

The only thing she did for half a day was going to school like always, and then went home before going out to look for the 'pyschopath killer' but ended up with a green creature, the goblin. Beat it until unconscious and end its life with a knife in the heart. The cold corpse of it still resides inside the inventory.

"Perhaps..."

『

— Health Potion x9

— Consumable Food x10

— Consumable Bottle of Water x10

— Knife 』

"I knew it!"

The goblin's corpse is gone from the inventory, which means it is one of the requirement. Does it also count that she's level 10 now? Perhaps, both of the above is the requirement. Sheila nodded her head before shrugging her shoulders and said.

"Anyway, I'm not going to the Second Floor yet. Let's kill up some slimes for now."

A brand new knife suddenly materializes in her hand. She gripped it hard before giving it a couple of practice swing in order to get used to it. After she was done practicing, she starts to look for a slime to hunt.

 Stab! Crack! 

 Stab! Crack! 

 Stab! Crack! 

...

Sheila frowned deepen after killing 40 slimes within 6 hours. She should have leveled up by now, but when she checks her status, it was still showing at level 11. Because she was in the Trial Tower, she couldn't see the experience bar like the one she saw on the phone.

Sheila feels like she's missing something. Since she could enter the Trial Tower again, maybe she should leave for a while and look up the experience bar on the phone to see if it increase or not.

『 Do you want to exit the Trial Tower? 』

    『 Yes/No 』

Within the blink of an eye, she was already in her bedroom. She picked up the phone on her bed and opened up the leveling system.

"...it didn't increase at all."

She had spent 6 hours.. of killing slimes without getting a single experience— It was truly a waste of time. Sheila gritted her teeth at the thought.

"Perhaps, my level is already higher than the slime, and so I couldn't get any experience from them anymore?"

That might be the correct assumption. Sheila falls on her bed in exhaustion. Ugh, my six hours was waste for nothing! She rolled around in her bed as she complains in her mind.

Before entering the Trial Tower, she had to go to the convenient store to refill the consumable food and water. She still had plenty of it stored inside her inventory, but the more she had it, the better. She has to be extra careful and cautious since she didn't know what's in store for her on the Second Floor. But since the goblin's corpse was taken away from her, she could guess what kind of monster she had to fight; it was obvious isn't?

It has to be the wicked green creature that most would see in a fantasy world, the goblin.

Huh, you thought the green creature was h*lk? I recommend you to watch the goblin slayer get to know more about the goblin. The lore of the goblin is well explained in that anime, after all. But it's not my fault if you get PTSD from it.1

Joke aside, after taking 20 minutes of replenishing her inventory, she decided to take a warm bath first. It's essential to take a bath every day, you know? Especially a warm one.

"Fuah~ It feels good~"

Sheila moans while submerging herself in the warm bathtub. She wonders, is it in Asian bloodline that she enjoys taking a warm bath so much? Probably not, she has seen the other who is not Asian also enjoys it as much as her. But some people didn't enjoy the bath that much to the point that they would rather take a bath only once in three days. Maybe because they didn't sweat or smell that easily, but still, if she didn't take a shower for a day, she would already feel uncomfortable.

After cleaning both the mind and body, Sheila was ready to go.

『 Welcome to the Trial Tower! 』

『 Do you wish to ascend to the Second Floor? 』

『 Yes/No 』

"Yes."

She immediately closes her eyes after saying it. From the brightness of sunlight that she could see even with her eyes closed, but now turned into pure darkness. Sheila slowly opened her eyes.

"This is..."

In front of her stood a big hole deep in the mountain. The darkness inside of it was like that of an endless abyss, and she couldn't see the end of it. She looked at her surroundings and noticed that a vast forest surrounded her. She tried walking toward it, but the invisible wall stopped her.

"...I have to enter here, huh."

Sheila let out a sigh as she looks inside the dark abyss, Cave. When her gaze went inside it, she could feel her sixth sense warning her that it is very dangerous ahead. It was just like the feeling she got when she had come across the Slime King.
