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

A bottle of mineral water suddenly materialized in her hands. Sheila opened up the cap and drank it in one gulp. Her thirst finally diminished a little bit. In just one thought, the status and quest window pops up next to each other.

『 Sheila LV.11 』

『 HP: 90/90 MP: 80/100

—STR: 20 —INT: 20

—AGI: 13 —VIT: 18

—LUCK: 10 AP: 10 』

『 Goblin Slayer 』

『 Kill all goblin inside the cave. (7/10)

Reward: 5 Attribute Points

Punishment upon failure: Fate worse than death 』

It seemed that one cost of the fireball is 20MP, that means she could use it five times, but she didn't know what will happen once her mana reaches zero. In some cases, her body will only get tired as if she had just run a marathon. But in the worst likely case, she could be put onto unconscious after using the last fireball which would endanger herself without a doubt.

She couldn't test it out here due to the danger still brew inside the cave and maybe, also on the outside. Perhaps once she gets out of the Trial Tower, she could test it out somewhere which is devoid of people. Although the mana outside is too little compare in the Trial Tower, conjuring the fireball spell that she had acquired from the skill should be easy to do.

Sheila noted down what she was going to do when she left in her mind before a bread materialized in front of her. But before she eats, she checks up the status for a confirmation.

『 Sheila LV.11 』

『 HP: 90/90 MP: 85/100

—STR: 20 —INT: 20

—AGI: 13 —VIT: 18

—LUCK: 10 AP: 10 』

"Let me see..."

It has been five minutes since the fireball she has cast. Does this mean that the mana regeneration is one per minute? Since she has got 100 MP, she had to rest for about 1h and 40minutes for it to fill up from zero. That's pretty interesting, Sheila thought as she nommed on the bread. She just needs to take a rest for about 15 minutes before her mana is all filled.

While she was resting, she didn't let her guard down as she would occasionally use Presence Detection. The amount of mana used for it depends on how far she could reach. At the skill Lv.1, she could reach as far as five meters at the cost of 30MP. But the amount of mana could go down as low as 1MP if it was around a meter or so. That was what she did after every two minutes while she was resting. It took her for half an hour.

『 Lottery 』

『 1 Draw — 50G

10 Draw — 500G 』

『 Gold: 500 』

The lottery window suddenly pops up in front of her. After killing the goblins, some of them dropped a gold coin which sheila immediately picks it up. She didn't check how much gold had accumulated, and when the lottery surface in her thought, the lottery window appears in front of her.

Sheila smile in happiness when she thought of the ten draws that she could do and wonders what she would get from it. Since she had managed to create two skills in the time she was here, she thought that perhaps, she could gain something nice from the lottery.

Before giving a thought to click on the ten draws, Sheila decided to give her prayer to the RNG God firsthand. She doesn't know what's ahead of this cave, but she could tell that it would be dangerous. And so, why not use lottery? Or so she thought. Maybe she might acquire something that could potentially be a trump card for the future.

And with a thought, the lottery starts spinning and gaining the speed in no time. Now, all she had to do was to give it a thought for the spin to stop. She tried focusing on the lottery spins, but she couldn't catch up with her slow eyesight. She desperately prays to God above or the underground, whenever it is, Please give me something good!

The lottery spin starts to slow down, and before long, the result came out.

『 You have killed the Goblin LV. 6! 』

『 You have completed the quest! 』

『 Goblin Slayer 』

『 Kill all goblin inside the cave. (10/10)

Reward: 5 Attribute Points

Punishment upon failure: Fate worse than death 』

"I'm finally done with this."

Sheila let out a sigh before falling on her butt to the ground. The last three goblins were actually grouped up together when she found them. But thanks to the flame magic, she managed to beat them up with little injuries. Though the fight takes a lot longer than any match she had been into so far; It was a very exhausting fight for her. If she were given to choose between the fight or staying awake for 24h gaming, she would instead go with the latter choice.

Or maybe she would even choose to go after 24h of anime girls shouting 'Ayaya'. That was how exhausting the fight was to her.

No, wait. You can ignore the last one. I wouldn't do that even if someone paid me. I had enough of PTSD from the goblin slayer.

『 Do you want to exit the Trial Tower? 』

      『 Yes/No 』

...

After coming back to her home, Sheila didn't immediately go out to test the plan she had. She picked up the phone before opening the leveling system app and went to the newly opened function, The Shop. It was not actually new since Sheila had seen the function unlocked after the fight against the Slime King. No, to be exact it was because she had picked up the gold coins dropped.

When she decided to keep the gold and exit the leveling system, she noticed the shop being unlocked after exiting the lottery windows. Of course, she was so surprised that she accidentally drops her phone. It was a relief that she was on her bed. After getting over the shock, she immediately opened up the shop function and was dazzled by the item inside of it.

The shop has everything that she would need in all kind of situation such as weapons, all-type of the potion, skill books, etc. It was freaking amazing. But of course, the price was also deadly with the zeros right behind it. Imagine seeing a skill book called Fly Magic right in your face, but the price for such a book is tremendously huge. It's blocking her path to become a Superwoman!

Joke aside, anyone could tell how happy she is when she browse to the shop. But the only thing you could do is Buy and Sell. Even so, the items inside the shop were way too godly, and some are even unbelievable. She had to repeat it because of how important it is to her.

She went to the potion section in the shop, and within minutes she had already found the potion she was looking for. It was none other than mana potion.
