Magic System in a Parallel World

Leo watched as his mana dropped by nearly 500 every second, then recovered 275 half a second later because of his mana regeneration and the high-quality mana potion.

'Please hurry up, Miss Camille! I can't hold on for much longer!' Leo cried inwardly as he could feel his body getting weaker with every passing second.

A few moments later, right as Leo was about to run out of mana, a massive magic circle suddenly appeared in the sky above the monsters.

This magic circle was golden and incredibly complex with thousands of symbols within it. Furthermore, it emanated a holy aura that made it seem as though a divine entity was descending.

Camille took a deep breath before muttering in a cold voice, "Even if God forgives you, I will not— Divine Punishment!"

Whoosh!

A massive golden sword suddenly emerged from the magic circle and smashed directly onto the Fiend Warrior, causing the entire Giants' Valley to tremble.

A powerful explosion occurred the moment of the impact, and a blinding light illuminated the whole area the following second, almost as though a flashbang the size of a nuke had been denoted.

Camille quickly descended from the sky and landed near Leo and Nina after unleashing the devastating attack, feeling incredibly weak due to mana fatigue.

Despite her massive mana pool, she'd just overcharged a Tier 7 magic spell to its limit, so it would be weird if she wasn't out of mana.

Leo rushed over to Camille to see her condition.

"Are you okay, Miss Camille?!"

"Lower your voice. I am fine…" She said.

"That was freaking amazing! How can you be a healer and unleash such powerful magic spells at the same time?! Or are all healers this powerful in this world?"

"You think that was powerful? That was pathetically weak for a Tier 7 magic spell. If it were any other magic affinity, it would've been enough to destroy a whole mountain," she sighed.

"Is that so… Even if that's—"

"LEO! TO YOUR RIGHT!" Lilith suddenly shouted at him.

Leo turned to look over his right shoulder to see the Fiend Warrior climbing out of the large crater caused by Camille's magic spell.

"It's not dead even after taking that magic spell point blank?!" Leo exclaimed.

However, even though the Fiend Warrior had managed to survive Camille's Divine Punishment, it had only barely managed to survive. It was in a horrible condition with its body covered in its own blood, and it was even missing one of its arms.

"Leo! Get out of here! I will deal with it!" Camille quickly said to him.

Leo turned to look at her and smiled, "What can you do in that condition? You can barely stand up, much less fight the Fiend Warrior. Don't worry, it's heavily injured. I should be able to handle it in that state. Leave this to me."

"Nina! Take care of Miss Camille! I'm going to finish off the boss!"

"Y-Yes!" Nina quickly rushed over to take his place.

Meanwhile, Leo retrieved his red sword and approached the Fiend Warrior that could barely stand still.

The Fiend Warrior released a beastly roar as it suddenly raised its left arm before swinging its cleaver down.

Leo quickly cast Feather Step before dodging the attack.

"Lilith! Is there anybody else nearby?! I want to use magic!" Leo suddenly asked her.

"Give me a moment!" Lilith flew into the air and began scanning the area while continuously dodging the Fiend Warrior's slow but heavy attacks.

"Leo! I can see Valery's team in the distance! They're approaching this place! If you want to use magic, you need to hurry up and defeat the Fiend Warrior! Valery and her team will arrive in a minute!"

"I understand. Thanks."

Without needing to worry about being seen using magic, Leo immediately began throwing Void Spears at the Fiend Warrior.

'I don't have much mana left. I'm going to use as many Void Spears as I can before I finish it off with my sword!' Leo thought to himself.

Boom! Boom! Boom!

Leo threw Void Spears after Void Spears at the Fiend Warrior, further weakening it.

About a minute later, Lilith shouted, "Leo! Valery and her team will be here any moment!"

"Alright!"

Leo overcharged his last Void Spear as much as possible before throwing it in the Fiend Warrior's face.

BOOM!

The attack was strong enough to stun the Fiend Warrior for a moment and bring it down to its knees.

When he saw this opportunity, Leo tightened his grip on the sword and jumped on top of the Fiend Warrior's shoulder.

And right as Leo raised his sword into the air, Valery and her team arrived at the scene to witness the moment Leo swung his sword down.

"Haaaa!"

Leo released a loud war cry right before swinging down his sword, decapitating the Fiend Warrior's thick neck in one swift movement.

Dong!

The Fiend Warrior's large head fell to the ground a second later, causing the ground to shake slightly.

<You have been awarded 10,000 Magic Points for slaying the Wilderness Boss 'Fiend Warrior'>

<You have been awarded 150,000 Magic Experience and 5,000 Magic Points for clearing 'Giants' Valley'>

"A-Am I seeing things, or did Leo just kill that Fiend Warrior…?" Kevin mumbled in a dazed voice.

"I don't want to believe it, but the evidence is right before my eyes…" Jennifer swallowed nervously.

"…" Valery and the others silently stared at Leo's figure with wide eyes.

After killing the Fiend Warrior, Leo went to remove its mana core, which was twice as large as the Black Wyvern's mana core.

He acted as though he didn't notice Valery and her team and went back to Camille and Nina's side a moment later.

"Here you go, Miss Camille. Since you did most of the work, this mana core belongs to you." Leo handed the mana core to her with a bright smile on his face.

"..."

Camille was left speechless by his actions.

"What you did was very reckless… but I'm glad that you did it." Camille said with a slight smile on her face a moment later.

"That mana core, you can keep it. Consider it a reward for your bravery."

"Really? Then I won't be humble! Thanks, Miss Camille!" Now with an even brighter smile on his face, Leo tossed the mana core into his Spatial Ring.
