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

『 You have accepted the quest. 』

『 The monster will be spawned in 3.2..1. 』

『 You can't exit the Trial Tower before completing the quest! 』

Ria was expecting to see a group of monsters to spawn right in front of her, but there's nothing in her sight. I guess I was lucky? Even though there seems to be no visible monster in her surrounding, she didn't put down her guard. She had never fought in her whole life, which was why she was more careful and wary in this place where she could potentially lose her life. Of course, she is afraid but being afraid is not the right thing to do at the moment. What she needs to do the most is to leave this place and later on give a good amount of scold to Sheila.

It was Sheila that bring her here into this strange place, after all. When she entered this place, the key that was in her hand had disappeared. She didn't know how and where did it go, but she thought that perhaps, by clearing the quest, she could leave this place. Maybe the key would even appear the moment she completed the quest. 

Ria slowly walk as she warily watches her surrounding, she didn't know how the slime look like, is it small as a lump of water in the shape of a football? Or is it as small as ping pong ball? Either way, it never hurt to be wary and survey her surrounding as she might find them first before they could launch a sneak attack on her. It's very dangerous to her since she didn't know how to fight even with the silver sword in hands, one sneak attack could lead to a fatal injury. 

With a small step one at the time, even slower than a turtle itself, Ria walks while she is surveying the area onward as not to miss anything. It was long until she came across a single slime bouncy away in the distance. The slime was coloured in blue, and she could see through the inside of it that there's a small stone that keeps on moving around once she gets closer to it. 

She had wanted to make a sneak attack on the slime, but a beginner like Ria couldn't possibly hide her presence against it. The moment she was close enough, within the range of the slime, it immediately bounces and heads toward her. Ria gripped hold of the silver sword in her hands and dash forward; the slime eagerly jumped at her when she arrives approximately close to it. 

But before it does, Ria swings her sword at it blindly. It was a stroke of luck as the slime jumped right in the direction of the swinging sword and it ended up slashing the core inside of the slime into two. Her first fight has smoothly ended with luck on her side. Ria was quite shocked herself since she didn't expect the fight to end that fast and very easily. Once she calms her mind, she just thought it was a lucky win, and the next time she fights such a stroke of luck wouldn't possibly happen again.

『 Cilia have killed Slime LV.1! 』

Such an announcement didn't appear or heard by Ria as the only thing that can be one of the evidence that the slime is dead is the water that splashed onto the ground. The other one is in the quest as the detail changed from 0/10 to 1/10. She didn't stay in one place too long before moving on in search of a solo slime. It was a common sense that one could fight against one opponent if their strength is weak, but if the weak gathered up together, even the strong could get beaten by them.

It was especially so for someone as weak as Ria. Getting surrounded by slimes is no joke. This is also not an R18 game where such an incident would be a sore sight for the gentleman. Slime would just devour her rather than doing something pervert; this is not like in a game after all. 

Ria managed to find a single slime and in no time beaten it with the swing of her sword. She did get hit by the slime, but as her profession is that of a healer, she could heal the injury easily. The cost of one heal depends on the wound, if it's a small one, then it wouldn't cost much less than 5MP. The most she could do is healing one almost fatal injury at the cost of all her MP. How did she know? She tried it on herself and made her conclusion base on the experience. 

『 Healing Magic LV. 1 』

『•Heal [ 5-25MP <30s> ]

Heal small injuries (one almost fatal) 』

Thankfully she didn't need to recite a long chuunibyou-like chant that she saw in anime. It would be utterly embarrassing as an adult to do such a thing. All she needs to do was to say the spell name be it in a whisper or normal voice and imagine herself being enveloped by light. If she could see herself in the mirror, then she would have thought she was witnessing a Saint due to the light surrounding her whole body during the healing moment. 

Even Sheila, who was currently watching, had such an impression when Ria healed herself. Too bad she didn't have her phone in hands, or she would have snapped a picture by now. It was, indeed, a beautiful sight. Anyway, one heal cost 5MP, and she could only cast it once every 30 seconds. And she only needs to take a five minutes break to fill up the mana back to full. It took her about five hours to finally done with the quest. 

She was quite lucky that whenever she met a slime, it would always be alone for her to hunt. After the fourth slime, she had gotten used to wielding the silver sword. And whenever she took a break, she also finds out that there's a portion of food in the inventory. She didn't know where it came from, but it was a good thing so who cares. 

But after she completed the quest and leveled up by one, she was not sent back to her world, nor the key appears before her. She was still inside the space called Trial Tower. She was going to panic again when suddenly a figure materialises in front of her. As once a normal person, she was obviously mesmerised by the magical sight in front of her. But that came to a stop when she saw the figure was apologetically bowing to her. A female figure could be seen bowing down to Ria on her feet and didn't seem to care whenever the sight was unsightly or not.

It was none other than Sheila.
