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

On the Third Floor, inside the Trial Tower.

『 You have killed the Goblin LV.7! 』

"Hmm, this is weird. I don't see any new monster so far on the Third Floor."

Sheila had also thought the Third Floor would be a different place, but it was merely another cave. And she had only found goblin so far. But Sheila did notice a difference between Second and Third Floor, and that is Sheila met goblin way earlier. On the Second Floor, She didn't just meet goblin the moment she entered, but here on the Third Floor, the goblin was already waiting for her right after she entered the cave. 

From when she had entered until now, she had already killed five goblins. Some of them were alone while there are some that group up with each other. But it was just a walk in the park for her now with APW in hands. Oh right, I didn't show this weapon to Ria before. Maybe I should do it later just to see an expression of amazement on her face when APW transform from a bracelet into a sword. That sounds like a good plan, but for now, She's going for deep dive in the Third Floor. She wanted to know if there's really no new monster for her to fight.

She was slowly stepping forward while not making as much noise as possible. She could definitely break out of getting surrounded by a group of goblins by massacre her way out of it, but if a new monster pops in, she is not so sure anymore; there's even the possibility of her losing if that happens. That was why she is careful and wary in this unknown territory. 

"Another Goblin, huh?"

Like a ghost, Sheila silently approaches the goblin ahead of her. But the goblin notices a small noise from her which resulted in the fight to end for one second more. Nothing will change even if the goblin noticed her far ahead; in the end, the goblin was just too weak for the current Sheila. When Sheila was going to pick up the gold dropped from killing the goblin, she jumped back from her previous location and saw a lump of jelly ahead. 

"Ah, that scared me. I thought it was a new monster for a second there."

Sheila breathes out a relief sigh when her eyes caught the slime in front of her. 

"Wait. Slime? In the Third Floor? Is the monster on this floor consist of goblins and slimes?"

That's hardly a challenge for her. It didn't take her a minute to kill the slime in front of her before proceeding to pick up the gold on the ground. Maybe there's more to it, a goblin variant like the previous floor boss? Either way, she had to be careful while diving deep into the cave.

As Sheila dive further, she only came across more goblins and slimes. Some of them are attacking separately while some were working together to defeat her, which was impossible for them. It wasn't long until she heard a notification of her leveled up.

『 You have leveled up! 』

『 Sheila LV.15 』

『  HP: 98/110  MP: 150/150

GOLD: 1150

  —STR: 23 —INT: 30

  —AGI: 20 —VIT: 21

  —LUCK: 10(+2) AP: 15 』

"I'm already halfway to level 20."

She had been fighting with only APW and no magic in this floor since her opponent is just slimes and goblins. That was why sometimes she couldn't wholly dodge and thus was hit by their attacks, but then again, it wasn't much that of a fatal. Anyway, now that she had collected quite an amount of Attribute Points, it's time to distribute them.

『 Sheila LV.15 』

『  HP: 98/115  MP: 200/200

GOLD: 1150

  —STR: 25 —INT: 40

  —AGI: 21 —VIT: 23

  —LUCK: 10(+2) AP: 0 』

"Nice. Now I can feel that the mana inside of me is increasing quite a lot."

It wasn't just that, she could also feel that mana flow smoothly through her body, and if she ever cast a spell, it would be double more powerful than before. Basically, her control in mana has gotten better. 

To be honest, she likes the feeling of her growing stronger. It was like a normal growth, but this one feels more of an accomplishment to her than anything she ever did in life. It was just like the time she enjoys reading a novel where the character started up as weakling but only to slowly gets powerful as he advances. It was like seeing a child growing up from baby to kid and teenager. 

That was why she noticed a few changed that happened through her body. Her height has increased by ten centimeters from 177cm to 187cm! And it was not just that, her weight also—no, it was not because of fat. It simply due to muscle growth. Muscle and fat are two different things, while the former is good if it grows and the latter is bad. Who needs useless fat? Even if you cry on me, I won't give any of my pity on you, Fat. Your existence is not needed.

The Gurgle-sensei said that the growth period stopped when you're at 14-15 or more as a girl. So this could be explained that her current growth got something to do with her growing stronger. It seemed that the stronger she becomes, the body will also following along to adapt to her strength. Hopefully, she won't get too much muscle that it becomes like someone who trains to be bodybuilder, nuh-uh. Even though the muscle is good, having too much is not an option for a girl.

But then, why is she keep making a stupid mistake from time to time even though her intelligent attribute is so high? Due to Photographic Memory skill, she remembers every mistake she had done as clear as day. When she went through it, she thought this and that could go even better if she goes through that route. But it was already in the past; she could only hope that she won't make the same mistake ever again. But is that even possible as a human?

"Two goblins ahead."

『 You have killed the Goblin LV.9! 』

『 You have killed the Goblin LV.10! 』

『 Swordsmanship skill has leveled up! 』

"Oh?"

Sheila was surprised to see the Swordsmanship skill to leveled up. But it did make sense though since she had been using the sword and the skill ever since she had gotten APW. With the Swordsmanship skill now at level 3, Sheila could tell that the sword movement that she learned could be improvised. It was as if she had gained new knowledge from the skill. Well, nothing was surprising anymore at this point to her. It was fine so long as it makes her stronger, that is all that matter.

『 Cilia has entered the Trial Tower! 』

"Oh? I guess she must have finished her homework. It's time for this dive to come to an end, i have to go and teach her things."

***

"What? A junior at our school know about your secret?"

"Yes."

"That's not surprising; I mean knowing you, it was just about time."

"What do you mean by that?!"

"Sigh, I guess I still have to take care of you even after all that you went through as your stupidity is still there."

"I'm not an idiot! You're the idiot! Your whole family is the idiot!"

Ria just shook her head at her best friend angry remark like a mother to her child. Sheila must have been so offended that her eyes started tearing up, but there's no way an adult like her would cry, which was why she held it in. It was simply a cute sight in Ria's opinion. But she didn't go too far with her tease as she immediately went over to Sheila and gave her a warm hug while patting her back.

"It's okay, Sheila. Being an idiot is not a sin."

But her word ended up making Sheila cry for real. It took a while to calm her down when she burst out like that. It was at a time like this that Ria always thought Sheila is like a kid, but she won't say that to the person herself, or it might cause even more trouble. Is this perhaps her payback against the previous incident? Who knows. 

"You promise you won't say I'm idiot anymore?"

"Yes, yes, of course."

"You won't even say it in a roundabout way?"

"I won't."

Only then did Sheila calmed down. It's hard to calm down a kid when they started crying; Ria knows that feeling well.
