Magic System in a Parallel World

Diiiii… Diiiii… Diiiii…

Camille reached into her pocket and retrieved her ringing phone.

"Leo? Did something happen to him?" She frowned when she saw the caller id.

"Hello? What's wrong?"

"Ah, Miss Camille, there's nothing wrong, but I wanted to let you know that there might be a boss spawn happening soon in the Giants' Valley, and I am going to investigate it with Nina." Leo said to her through the phone.

"What?! Boss spawn?! You idiot! Stay away from it! If it's an S-Rank monster, you'll be killed!" Camille quickly exclaimed.

"Don't worry, we're not going to confront it unless we're certain that we can defeat it—"

The connection suddenly cut off.

"Hello?! Leo!" Camille looked at her phone to see that the call had ended.

"Damn it!"

Camille quickly retrieved her Adventurer's equipment from her Spatial Ring and wore them before flying into the Giants' Valley to look for Leo.

Meanwhile, inside the Giants' Valley.

"Why did the connection suddenly close?" Leo looked at his phone with raised eyebrows.

"Huh? It's not working? D-Don't tell me that it's broken! What the fuck! That was my first call since I got the phone! Durable, my ass! I was scammed!" He began panicking when he realized that his phone had stopped functioning, and his heart began bleeding from pain, as he'd spent half a million on this phone.

"Umm… I don't think your phone is broken. I think it's because of the mana disturbance. If the mana disturbance is too strong, it can cause electronics to become unresponsive and even block their signals, almost like a natural jammer." Nina said to him.

"I hope that's the case, or I've just wasted half a million dollars…" He sighed.

"With the amount of money you'll make from selling the mana cores you've collected throughout the training course, half a million might as well become spare change." Lilith chuckled.

"Even if I have a billion dollars, 500 thousand dollars is still 500 thousand dollars— its value won't change." He shook his head.

Sometime later, they arrived at the location of the mana disturbance, which was an open field. However, Leo and Nina were not the first ones there.

"Look over there! What are they doing?" Leo pointed at the dozens of monsters that were gathered in the center of this open field, almost like they were doing some kind of ritual.

"I think they're anticipating the boss spawn," said Nina.

"So it's really going to be a boss…" Leo swallowed nervously.

Sometime later, Leo asked, "How long does it usually take for the boss to spawn? We've been here for an hour already."

"Who knows. This is my first time seeing a boss spawn." Nina said.

"It usually takes a few hours, but it can take several days as well if the boss is extremely powerful." Lilith said.

"So the quicker the boss spawns, the weaker it is?" He asked.

"Something like that."

Leo and Nina continued to wait for the boss to spawn while more and more monsters gathered in the area.

Four hours later, Nina suddenly said, "Leo! Something's happening!"

She nudged him, who had fallen asleep from waiting, awake.

After waking up, Leo narrowed his eyes at the scene, but he didn't see anything different.

However, a few more minutes later, Leo and Nina watched as a massive red portal suddenly appeared above where the monsters were gathered.

The monsters began roaring in excitement when they saw the portal.

What transpired the following moments left Leo and Nina speechless.

From within the red portal appeared a massive red leg that was around 15 meters tall, followed by a muscular red arm, then a large head with a fierce face and two black horns.

Once this red-skinned monster was fully out of the portal and standing straight, it was at least three times as big as the Mountain Cyclops. Furthermore, this monster had two large cleavers strapped to its back like it's some kind of warrior.

"What kind of monster is that?" Leo asked Nina.

"I don't know… but its mana is overwhelming— even stronger than those entities we fought during the Elder's trial… much stronger!"

"Much stronger…? So it's an S-Rank monster?" Leo mumbled.

"No, it's not." Lilith suddenly said.

He looked at her and asked, "Do you know what kind of monster that is?"

She nodded, "It's a Fiend Warrior. They're not S-Rank monsters, but they're at the top of A-Rank monsters, probably top 100 in terms of prowess."

"Do you think we have a chance to defeat it?" Leo then asked.

Lilith pondered for a moment before speaking, "If you're thinking about fighting it without magic, then you won't have a chance. However, if you use magic… I think it's doable."

"Magic, huh? That's a little risky, considering that Valery and her team are also in this place. There could also be others that are watching in secret." Leo mumbled to himself.

"Leo, I don't think we should fight it." Nina suddenly said.

"It's too powerful. Even if you use magic, there's a good chance that we won't be able to defeat it."

Leo narrowed his eyes at the Fiend Warrior.

After a few moments of silence, he nodded and said, "Let's get out of here. There's no point risking our lives fighting it. I may be stubborn at times, but I am not stupid. We gain nothing from fighting that dangerous thing."

Furthermore, they were still in first place. With that being said, even if they were not first, they had no reason to fight a monster that exceeded their capabilities; it simply doesn't make any sense.

As Leo and Nina left the scene as quietly as possible, Leo subconsciously turned around to look at the Fiend Warrior again, and what he saw made his eyes widen with shock.

"N-Nina! Look!" He called out to her.

"What is it?" Nina turned to look at the direction he was pointing.

Her eyes also widened when she saw the scene Leo was watching.

"What the hell is going on…?" she mumbled in a dazed voice.
