After killing the first slime with one slash of the sword, she figured the slime weakness, which was the core in their body. But even so, She didn't put her guard down when fighting against them and she only fights when the slime was alone. Although the slime attacked didn't decrease her health that much, which only at 1-2HP from one single attack, but that doesn't mean she didn't feel the pain. Another point is if they surround her, her fate could only be death. There was a saying, one ant could not do anything to an elephant but what if it was an entire army of ants? They could get inside the elephant's ears and bit everything on their way to its brain before slowly killing it.

"Even so, everywhere I go, there are only slimes, huh..."

Sheila looked at the slime bounce up and down in her views distant away from her current camp. If she gets close to a certain distance, the slime would immediately go into battle mode. Right now, she was one meter away apart from that specific distance. Currently, she was resting her tired body after slaying three slimes. Her stamina could be considered as average, but due to swinging around such a heavy sword, her strength depleted as fast as water flows down the stream.

Looking at the window in front of her, the girl was pondering on how to distribute her attribute point once again. Currently, she was in dire needed of strength and vitality. But she couldn't let go of agility too. Five minutes later, she comes to a decision.

『 Sheila LV.2 』

『 HP: 30/30

MP: 50/50

AP: 5>0

—STR: 4>7

—INT: 10

—AGI: 3>5

—VIT: 6

—LUCK: 10 』

Looking at the changed of her status, she nodded her head. After she distributed three points into STR, she could feel her strength increasing. Now, she could swing her sword even more proficiently. While she was resting, she was also pondering on what is this 'Trial Tower' about. She could only look for information by browsing her surrounding, but all she could see is simply grassland that knows no end, also some slimes along the way. It doesn't give off the feeling of an 'Instant Dungeon', but instead, she feels like she was sent to another place somewhere on Earth if not of the slime.

"Quest..."

Sheila softly muttered, and the quest window appears in front of her.

『 Monster Slayer 』

『 Kill 10 Slime. (4/10)

Reward: 50 EXP

Punishment upon failure: Death 』

She nodded her head when looking at the progress of the quest. She only needs to kill six more slimes, and the quest would be completed. Sheila looked at the sky and noticed that there was no sun, yet she could feel the heat coming from the sunlight on her skins. She didn't know how long she had been in this place, probably around 3-4 hours have passed.

She's also worried about what would have happened if her mother intrudes into her room and finds out that she was nowhere to be seen? She didn't know if the time here passes the same as outside, she had read a novel about how one hour in the dungeon is equal to one day in real-time. She was wondering if this instant dungeon mechanism also works like that.

Sheila shakes her head at that thought, for now, it would just be a waste of time. It would be more appropriate to spend her time now on completing the quest faster; the others could be deal with for later.

Looking at the rusty sword by her side, she frowned and thought, it would be nice if the sword is not rusty but as sharp as new one instead. She encountered a bit of problem when slaying the slimes due to the sword sharpness was so dull that she feels rather than a sword, its more like using a blunt weapon instead.

But a blunt and rusty sword was way better than her weak bare hand. Only when her strength increased to a sufficient level would she have the confidence to beat the slime to death with just a punch. Although her strength has increased to 7, it was still on the level of a healthy adult man. Slime's jelly-like body could be destroyed easily, but it would not kill the slime, only by destroying its core would the slime be killed.

"I guess I had enough of resting and its time to hunt another slime."

She swings the sword for a couple of times before assuring that she was ready and walked slowly toward the slime in her views. When she arrived approximately close to the slime's location, she put on stance prepared to fight with the sword aimed to the front as the slime bouncing on its way to her.

Byun! Byun! Byun!

The slime makes such a cute noise whenever it jumped as its jelly-like body jiggled. If not for the slime trying to attack her on every single opportunity, she would have like to keep one as a pet. Well, if she acquired some kind of taming skill in the future, it might be possible. But that's for the future; she could only kill the slime and complete her quest for now.

When the slime arrived in front of her, it took no time before jumping like a fastball toward her. She dodged it easily to the side as if, she had known that the slime would make such move before slashing the sword at the core of the slime.

Crack!

The sounds of the core of the slime shattered as the jelly-like body turns into normal water before the cold voice appears in her mind.

『 You have killed Slime LV.0! 』

That's five on the count. Another five more and the quest would be completed. Sheila looked around and noticed a slime ahead and runs toward it.

『 You have killed Slime LV.0! 』

『 You have killed Slime LV.0! 』

『 You have killed Slime LV.0! 』

"Fuu... Haa~"

『 You have killed Slime LV.0! 』

『 You have killed Slime LV.0! 』

『 Monster Slayer 』

『 Kill 10 Slime. (Completed)

Reward: 50 EXP

Punishment upon failure: Death 』

『 You have completed the quest. 』

『 You have leveled up! 』

"Finally, it's finished."

Sheila fell flat on her back to the ground as the invisible burden on her body vanished along with the fear of punishment of failure. Although she acts optimism, deep inside of her, she was still scared of the fault. What would have happened if she had not found the rusty sword? Could she kill the slime with only her bare fists? Possible but not without getting hurt.

『 You could now exit from the Trial Tower. 』

『 Do you wish to exit? 』

    『 Yes/No? 』

Sheila looked at her surrounding for a moment before clicking on the 'yes', and like the previous experience, a magic circle suddenly appeared and lit up before her figure disappeared along with it.
