Swinging his sword while mana was channeled in, Sean swiftly cut the wraith of before once more.

"Kwaah!"

Having the bottom half of his body cut, the wraith screamed loudly before creating some distance from the human who hurt it.

Seeing that, Sean was about smirk to himself.

What stop him though was as he saw the wraith's body slowly regenerating.

The sand that was the wraith's vessel slowly moved back to the half it lost a moment ago. And before long the wraith seemed exactly as it did a moment ago.

"Hey! You know what does things are don't you? How do you get rid of them?" Sean asked the priestess while he looked at how the others did.

'This isn't good, the others have similar problems dealing with those things as I have. At this rate, we will be wiped.'

Gazing at the floating undead, Priestess explained with a frown on her face.

"They are undead of the second tier known as a wraith. Of the rarer types of undead that Sacred Cross is knowledgeable of, they are evil spirits that use mana to manifest their existence. Anything other than attacks with mana or life force would be useless against them! Magic is more effective against them!"

Hearing her explanation, Sean's expression didn't turn for the better.

"Use magic! Use magic against them! If you can't use mana then your life force!" Sean yelled to all the others.

As the others were lost on what to do, Sean's voice borough some clarity back to their sense.

But even after using attacks that contained mana or life force, the actual damage was neglectful against those wraiths.

But even if the wraith's sand body had been cut or crushed, they started to soon regenerate back to their full form.

"It isn't effective enough..." He mumbled while looking at the priestess.

"You holy magic should be effective against them, right? Or you light?"

"The Holy light miracle should be, but I only have an offensive miracle, which doesn't work on flying enemies..."

"Doesn't matter, use your light..." Sean said as he fend off a wraith hiring under the stairs.

Nodding her head, she stopped at the chairs while she began casting.

Raising her staff high, the warm light filled the floor.

"[Holy Light]!"

The next moment when the light hit the wraiths, they screamed undying howls as they put their arms in front of them to fend off the light from hitting their faces.

"Khaaaaa!"

"Kheetah!"

...

Watching the wraith's screaming of pain as if they were burned alive, everyone sighs in relief.

Unbeknownst to them though, the scourging light that bought them immense pain to that undead. Also reminded them of an event in the past.

The next second, the sand in their body moved forward and created a shield that protected them from the light.

The priestess who saw that got surprised.

After the duration of the [Holy Light] finished, the wraiths were still there.

And without the light keeping the undead from moving, they soon would go and start their rampage on her group.

Preparing to cast [Holy Light] once more, she was quickly stopped by Sean.

"Stop, there is no use. Instead of wasting your mana, save it."

"But-"

Catch up with Isamu who now was protecting Sylva and the young magic caster from the nearby wraiths.

Sean caught hp and helped him fend the undead off.

"Isamu! We got to do something!" Sean said.

"I know..." Isamu said with a frown on his face.

Though he said that, he honestly didn't know what to do now.

Only two people out of all there's could potential fatal wound does undead. Them we're being the magic casters.

Worse of all, the wraiths started to act much more clear-headed than the undead was known of. Making it a losing battle for them.

"How about we kill the necromancer then?"

Unexpectedly, the one who voices out an idea was the young magic caster.

Hearing that makes the others glance at him confused before focusing back on the stairs and enemies.

Noticing the confusion, he elaborated.

"Though I ain't certain. It depends on the magic caster's ability, but if the summoner dies, so do their summons though."

"Are you sure about that" Sylva voiced her doubt imminently after.

In response, the young magic caster shook his head.

"No, I am not. I have no sort of knowledge such as the school of necromancy. What I am telling you is based on just boo of how to fight the undead."

Breathing heavily from his lack of stamina, he looked at Sylva.

"Does it even matter if I am right or wrong?

Only me and my colleagues have the ability to get rid of the undead in one go, compared to you who need multiple hits! If by killing the master of those things means stopping does things- aghhh- I can't breath!"

Shaking her head from the exhausted young magic caster, she looked at Isamu.

"What do you think Isamu? Should we try what he said?"

"..."

There was a moment of silence.

Isamu took a look at his party and considered if they should do it or not.

'5 of us against the necromancer...is it possible?'

Though it was a decision that was difficult to choose from. He didn't linger much coming to a decision.

"We will do it. Us 5 will kill that Necromancer."

It was either staying helping the others fend off against the undead or them killing the brain of that undead, it being what they considered the necromancer.

Hearing his decision, the group of five-speed ascends to the next floor.

"Everyone! We will kill the necromancer! Until then keep the undead busy!" Isamu yelled to all the other explorers.

Some thought that they were being abandoned and used as bait while others tighten their grip on their weapon and accepted their reality.

"You aren't allowed here!" One of the wraiths yelled as he rushed to kill Isamu.

Noticing the undead, Isamu prepares his greatsword to fend off the undead.

But before he could do that, a massive flame flew through the air.

The flame directly hit the wraith's, which resulted in it screaming.

"Master Azur-!"

Its screams became once hearable, became just a scream.

And with the flames dissipating, the wraiths that were hit were nowhere to be seen.

"Go! While we keep those undead busy, go and finish their boss!" The one magic caster who was responsible for casting the flame said.

Ignoring the fact that all wraiths halted their actions and stare at the spot where the one wraith died, Isamu tossed his head and went with the four others up the stairs to the very top.

"We got to finish this fast," Sean mentioned while looking at the huge broken-up gate.

"Yeah...but be careful, we don't know what that Necromancer had cooked for us..."

"Mhmm..."

Nodding their head, the first thing that got their attention except the huge gate was a skeleton who was kneeling to the ground in front of the gate.

"Priestess, is it an undead?" Sylvia said while aiming her bow at the kneeling skeleton.

Frowning her eyes for a second, she shook her head.

"No, it isn't an undead...yet. If I purify it then-"

"Don't bother" Isamu said with a harsh tone.

Walking forwards, he kicked the laying skeleton to the side and looked forwards towards the gate.

"That can wait later after we finished all undead. For now, save you mana."

"..."

As a priestess of the Sacred Cross, such treatment of corpses wasn't acceptable. But thinking of their situation she has to say that Isamu was right.

"Alright, let's go in..."

With Sean and him in front and the other three in the rear, they walked through the broken gate.

Greeting them was a wave of sunlight coming from the top of the roof together with the warmth that it brought.

The light that fell on this floor highlighted the beautifully carved pictures in the wall where each of them had a connection with each other.

"Wow..."

"Beautiful..."

Sylvia and the young magic caster were in awe of those pictures.

Sean and Isamu in comparison only had a solemn look on their face.

And the priestess's focus only lay in a picture that was messy carved and that had a person kneeling in defeat.

"Quite the nerve you have appreciating my home." A cold and deep voice called out.

Surprised by the sudden voice, they all became wary as they looked in the directions of where the voice came from.

"Ah..." The young magic caster subconsciously let his voice out as he started at the bring who sat on a golden throne.

"Welcome, to my tower..." The cold voice said.

Hearing that, they all frowned.

Stepping forward, Isamu raised his greatsword to his shoulders while pointing with the other at the seating armored figure.

"Are you the Necromance!?"

"..."

An awkward silence surfaced through the last floor.

As they were about to attack the eating figure, the seating figure laugh.

"Hahahahaha~"

Rising from his throne, the 2-meter tall figure said with a cold tone.

"Do think that you considered me as a necromancer from just those mere undead."

Gripping the sword that rested beside the golden throne and sheathing it out.

The armored figured to let his killing intent flood the whole floor.

"Foolish...."
