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

"Ugh. Beaft."(Beast.) 

"Peffert defmon."(Pervert Demon.)

"Do you want to get more or stay silent?"

"..."

"That's a good girl."

Ria said while patting on Sheila's head. Sheila couldn't do anything but just glare silently with her tearful eyes at Ria. Although her strength has grown even more than Ria, it doesn't mean that she didn't feel the pain of getting her cheeks squeezed. But of course, it wasn't much compared to the time Sheila had battled against the Goblin Shaman where there are injuries in her whole body. She wasn't joking when she said so, as the pain almost caused her to give up on everything. 

That was why she could handle it just fine. The reason she made it seem painful is that because it was her 'punishment'. She's totally fine, drinking the health potion is not really because she feels it too painful, not at all. 

"So, how do I hide this sword from others? I'm pretty sure I don't have the inventory as I did in the Trial Tower since the blue card doesn't seem to be in my possession."

"Actually, you do have it. The key is the blue card in the Trial Tower. It just changed to fit the 'theme' that I had adjusted for some unknown reason that I will rather tell no one." 

"This key here? And how do I do it then?"

"Like how you use it to enter the Trial Tower, do it by unlocking an invisible door but before you twist it, make sure to have a thought of inventory."

"...like this? Whoa! It works!"

A game-like menu appears in front of Ria. She picked up the silver sword at the side of the bed and tried to 'put' it into the inventory; the sword disappeared as it went inside the inventory and an icon of a sword coloured in silver appear in the list of item. She breathes out a relief sigh after putting the sword into the inventory.

"How is it? Cool, right?"

Sheila said while having a smug expression on her face as if proud of the masterpiece that had turned out from her modification to the key. As the host of the leveling system, she obviously could modify the key which required no cost whatsoever so long as she didn't add anything that it didn't possess. When she had first used the key herself, it didn't have that many functions which later on was added by her. It only cost gold, nothing much. Yes, it cost the gold she had saved up, Sniff. 

"Hmm, so-so. How about the status? Do I need to the same action while only changing the thought from inventory to status?"

"Yes!"

"Your luck is still highly ridiculous even though it's the second time I see it."

Sheila heaved a sigh and threw her hands into the air in defeat. If she was a person blessed by the Goddess of Luck, then Ria is the daughter of Goddess of luck. She was also still curious about why she didn't have any class, is it because she is unique due to being the host of the leveling system? Or is it because she didn't reach the required level for the test to acquire the class? Not having the information is really making her feeling stressed out since she didn't know what kind of path should she walk forward. 

"What is this AP?"(Ria)

"Attribute Point. Once leveled up, you will gain five attribute points which you can use it to distribute to any of your attribute other than luck."

"STR or Strength, I don't need to say much about this since you have experienced it yourself with the sword."

"INT or Intelligence, by increasing this attribute, your brain will be much more active, and it will also increase mana point beside the health point. One attribute point is five mana points."

"AGI or Agility, it increased your speed in everything, be it reaction speed or your thought process speed by a small amount for one attribute point."

"VIT of Vitality, this is important as it will increase health point by five with only one attribute point, which is the same for INT. It also improves health regeneration rates by a small amount."

"Health Point or HP for short, this is your lifeline turned into a digit. Make sure you always watch this whenever you're in a battle and NEVER, ever let it reach lower than five."

"Mana Point or MP for short, since you have already used your healer class skill, then you know what it is, so I didn't need to tell you more than that. Ah, but one warning, never let it goes down to zero since you won't be able to move your body when the time comes to it. Basically, you're dead meat in a battle if you become immobilised."

"As for gold, this is not important right now so you can ignore it. Do you understand what I'm saying so far?"

After she was done explaining everything that she knows about the status, Sheila asked for a confirmation from Ria if she understood everything which was given a respond back by nodding her head as affirmation.

"So, where do you think I should distribute by attribute point into?"(Ria)

"As a healer, I guess it must be INT?"

"You guess? You don't know?"(Ria)

"Well, I didn't have any class whatsoever, so I just distributed the point as I pleased — no regret since I gained a few good skill though. But I don't know much about your case since you're the first key holder."

"Basically, I'm your first test experimental rat?"

"No, no, no! How did you come to such a conclusion?! Just distribute your point into intelligence, since you only have one skill which also requires mana. It won't be a loss; trust me."

"Are you sure I can trust you on this?"

"Of course! Ah, but you can't blame me later if it's wrong, okay—No, wait! I'm just kidding, trust me! You can put all the blame on me later."

Sheila reassured Ria with her word while patting her shoulders, followed by a nod from her. From Ria's perspective, Sheila doesn't seem reliable at all, no matter how she thought about it. Even her word was not filled with confidence as Sheila usually did when playing games with her. Ria could only let out a sigh before deciding to put her trust on Sheila as she distributes the point.

After distributing the point into intelligence, she feels that she now understands the thing that she didn't know in the past. It was like Sheila said, her brain is more active than before. She guesses that this is the real reason behind Sheila's grades are getting better than before. Basically, she cheats her way out of it. 

"Hmm, this feels strangely weird."

"You will get used to it."

"I guess so, but how do I hide this key? I'm worried that I might lose it even putting it in my pocket."

"Indeed, that's a problem. I didn't add such a useful function like the key teleporting back to you after a certain distance away, (it cost too much gold, so I didn't add it)"

"What did you say? I can't hear your last word properly."

"It's nothing, hmm, how about this?"

Sheila brought out her phone from the pocket before opening the app and went straight into the shop. She browses through all sort of things before finding the item she wanted and immediately buys it. The item was stored right away into inventory so Ria didn't know what she bought since she was too slow to see it on the phone. But Sheila didn't let her wait as an item suddenly materialises in front of them.

The item is..a silver necklace.

"Do you like something with silver?"

"Hmm? Nope. I thought you might like it, though."
