Magic System in a Parallel World

Chapter 213 Clearing the B-Rank Labyrinth

"What now, Leo?" Lia asked him.

"Since we're already here, let's clear the Labyrinth and get some reward from it. It's going to be a breeze, anyway, especially since I could defeat even an S-Rank Adventurer." Leo said with a smug look on his face.

"What's with that smug look on your face?" Lilith suddenly said. "Don't get so smug because you defeated an S-Rank Adventurer. Not only was he quite new as an S-Rank, but he had severely underestimated you as well. Moreover, he used fire magic, which is ineffective against you. If it were anybody else, you would've died many times. In other words, you simply got lucky."

"So what if I got lucky? A victory is still a victory." Leo shrugged.

A moment later, the Devourer of Gods suddenly spat out a ring.

Leo quickly noticed this and went to pick up the ring.

"Isn't this a spatial ring?" He mumbled. "Did this belong to that S-Rank Adventurer?"

Leo peeked inside the spatial ring a moment later to find several magic artifacts and many potions stored within this spatial ring.

"Whoa! There's so much stuff here! As expected of an S-Rank Adventurer! That guy was rich!" A wide smile appeared on Leo's face when he saw the interior of the spatial ring.

'It's a pity that the invisible cloak used by the other assassins was a one-time-use magic artifact. I wonder if I can get one through the Magic System's Artifact Shop…' He wondered inwardly as he stored Matthew's spatial ring inside his own spatial ring. As much as he wanted to pour out its contents to look at them, he decided to wait until he cleared the Labyrinth.

Sometime later, they arrived before the metallic door to the boss room.

'This will be my second time fighting a Labyrinth boss, huh? I wonder what kind of monster is on the other side of this door.' Leo thought to himself.

"Are you ready?" He turned to look at Lia.

"Yes." She calmly nodded.

Leo took a deep breath and proceeded to open the door.

Despite its massive size and metallic material, the door opened with relative ease.

Upon entering the boss room, Leo and Lia were greeted by a small room that had a large waterfall and a pond at the end of the room, and bathing inside this pond was a snake-like entity with silver scales.

This silver snake resembled the Sea Leviathan on the sea floor, but it was much larger and longer, and it also had a pair of translucent wings on its back.

"Wow, that's a Flying Silver Leviathan, an A-Rank monster." Lilith said.

"You recognize this monster?" Leo asked.

"Yes, I have read about them in books. Unlike Sea Leviathans that can only jump in water, Flying Silver Leviathans can fly in the sky for an extended period of time. They can also use water and wind magic." Lilith explained.

"Duo magic, huh?" Leo mumbled. "This is the first time I've encountered a monster that can use two different magic affinities."

"Most of the time, monsters that can use more than one magic magic affinity aren't really proficient in magic. As for the Flying Silver Leviathan, it can probably use up to Tier 3 magic spells— Tier 4 max since it's a boss."

"What's your plan?" Lia asked him.

"It's quite simple, really. We just bombard it with magic until it dies." Leo said with a calm smile.

"Whenever you're ready." Lia said as she readied her magic rifle.

"Why are you still using that magic rifle? We're alone, so you can use your magic again." Leo said.

Lia glared at the Flying Silver Leviathan and said, "My gravity magic won't affect a monster of that size— at least not in my current state, and my dark magic isn't that strong yet. In other words, using the magic rifle is the best choice right now."

"I see… Then I will bombard it with magic and you'll shoot it from afar."

"Okay."

Once they were prepared, Leo started casting his magic spells.

Summon Skeleton Mages, Dark Aura, Shadow Clone— once they were all prepared, Leo released his magic spells on the Silver Flying Leviathan that was still relaxing within the pond beneath the waterfall.

BOOM!

The entire room shook as magic spells bombarded the pond.

The Flying Silver Leviathan was immediately enraged by the surprise attack, and it tried to fly into the air.

However, Lia was already prepared for this and pulled the trigger the moment the Flying Silver Leviathan's head appeared from the smoke.

The Flying Silver Leviathan released a pained cry as Lia's mana bullets exploded on its face, causing it to fall back down from shock.

Even with Lia's amount of mana, she was unable to penetrate the Flying Silver Leviathan's thick skin.

A few minutes later, Leo stopped when he received several notifications.

[+128 Magic Points]

<You have cleared a B-Rank Labyrinth>

[You have completed a Quest]

[+300 Magic Points]

"I think it's dead." Leo said to Lia afterward.

They went to check on the Flying Silver Leviathan's condition, and after confirming it was dead, Leo harvested its mana core.

"Alright, let's quickly look for any treasures before getting out of this place." Leo said a moment later.

Fortunately for them, the room was quite empty and small, so there weren't many places for the treasures to hide.

"It's either in this pond or behind the waterfall." Leo said as he stood before the pond that had been dyed red from the Flying Silver Leviathan's blood.

Lia looked at the red pond and spoke in a calm voice, "I will search inside the pond. You can search the waterfall."

"Are you sure? The pond is filled with the monster's blood…"

"Exactly." Lia said, and without saying anything else, she jumped into the water.

Leo couldn't do anything about it, as he didn't have the ability to swim.

As someone who had spent all of his time inside a room studying books, he's never had the chance to learn how to swim, not to mention that there was nobody to teach him, hence why didn't know how to swim.

Leo turned to look at the waterfall and approached it.

Meanwhile, one floor above them, Sarah and Oscar were still running away.

"Damn it! I hope Matthew isn't going to chase after us!" Oscar cried out loud.

"I think he was there for Leon, so we're probably safe… for now." Sarah said.

The two of them have been running nonstop since they ran away from Matthew.

Sometime later.

"There's nothing behind the waterfall." Leo sighed out loud as he walked out of a small cave that was hidden behind the waterfall.

When Leo could see the pond again, he noticed that Lia had also finished with her search.

"I found something." Lia showed him a necklace that had a blue gem attached to it.

However, Leo wasn't looking at the necklace. Instead, his gaze was on Lia's body, as her clothes were sticking to her skin due to it being soaked in water, revealing her slender figure.

Leo quickly snapped out of it and cleared his throat, "Can I see it? The necklace."

"Here." Lia casually handed the necklace to him.

"Let's see…"

[Necklace of the Sea]

[Grade: B]

[Description: Increases the effects of all water magic by 50%. All water magic will require 10% less mana to cast.]

'Water magic, huh? It's pretty useless to me.' Leo thought to himself after seeing its description.

"You can have it if you want it." Lia suddenly said.

"Eh? I don't really need it. I will sell it for some money and then we can share it."

"I don't need the money. I already have plenty," she calmly said.

"..."

Leo suddenly recalled that she was from one of the most powerful families in the city and that she could probably acquire as many B-Grade magic artifacts as she wants.

"If you say it like that, then I won't be humble and take it. Thanks." Leo tossed the necklace into his spatial ring without any hesitation.

"By the way, do you have spare clothes?" Leo pointed at her wet clothes.

"Yes, give me a moment. I will change right now."

Without even the slightest hesitation, Lia stripped herself down before Leo, who quickly turned around to give her some privacy.

"Why are you acting so embarrassed? It's not your first time seeing her naked." Lilith chuckled.

Sometime later, after Lia changed clothes, they began making their way out of the boss room after double checking there were no treasures left behind.

"Alright, let's get out of here before this place collapses. It's almost time for the monster nest raid, as well." Leo said before they left the boss room.

Thus, over the next several days, Leo and Lia would retrace their steps and make their way back up the Labyrinth.

"Hm? Isn't that Sarah and Oscar over there?" Leo noticed their figures in the distance, and they appeared to be fighting a monster together.

"Shit! This Labyrinth is so much more difficult without Leon! At this rate, we might not even make it back outside alive!" Oscar cried out loud as he distracted the monster while Sarah cast her spell from a safe distance.

And before Sarah could finish her spell, another magic spell came flying at the monster, killing it in an instant.

This startled Oscar and Sarah.

"Y-You! You're alive!" Oscar exclaimed after seeing Leo's face.

"What happened to Matthew?! How did you escape him?!" Sarah asked.

"Escape? I didn't run away. I killed him." Leo said with a calm look on his face.

"You killed him? An S-Rank Adventurer…? Impossible…" Sarah muttered in a dumbfounded voice.
