Transmigrated as a Ghost

"There's no end to them!" Lilia said frustratedly as she punched a skeleton rushing towards her to dust.

Currently, she, Alaric, Aurelia, and Zareen were surrounded on all sides by a horde of zombies and skeletons.

Each of these monsters were low level undead that were not particularly strong on their own, but their current numbers exceeded more than ten thousand.

Of course, even these many undead monsters had not reached a threat level greater than an annoyance for Lilia and her party. A bunch of monsters in the single and low double-digit levels were not going to be able to harm them.

Still, thanks to being in the sewers, none of them could launch any massive attacks to wipe out the undead horde all at once. If they did, they would likely collapse this section of the sewers and the city above it.

"Force Cannon."

Casting the tier two force magic spell, Lilia launched a small projectile of pure kinetic energy into the surging wave of undead.

This attack blew apart the monsters at the front of the line and destroyed several hundred more as it pushed the tide of skeletons and zombies back.

Still, the spell eventually lost its potency and the seemingly endless mob pushed aside their fallen comrades and continued to charge towards the sources of life calling to them like moths to a flame.

At the same time from another corridor, Aurelia had the six glowing balls from her Versatile Luminescence Unique skill floating around her head and firing off a rapid barrage of light blasts.

All of her attacks were restrained to prevent causing too much damage to sewer's walls, but they still cut through multiple skeletons and zombies with each shot.

From a third direction since they had been caught at a t-intersections, Zareen unleashed a constant stream of fire from her mouth. The low-level undead swarming them lasted less than a second against her flames and were reduced to piles of ash.

"Alaric, have you found the best way out yet?" Lilia asked, once again blasting through the endless swarm of zombies and skeletons coming at her.

"I'm trying, but there is a lot of movement coming from every direction. It's difficult to concentrate my wind magic with so many reactions. Ah wait, I think I just found something!"

Lilia waited expectantly for what Alaric had discovered, but unfortunately it was not the good news she was hoping for.

Instead of a way out, he had discovered the cause of the undead incursion hellbent on killing them.

"I'm not sure exactly what it is, but around a kilometer away to the west is a far larger undead monster. From what I can tell with my magic, its spewing zombies and skeletons out of its mouth and replenishing their numbers. Wait! It suddenly disappeared.

Spreading out his wind magic, Alaric tried to find the monster again, but it was not until around three minutes later that he located it.

However, it was no longer down the western corridor, but had appeared down the southern one that Zareen had nearly cleared out.

"How did it get all the way over there so fast? You did not detect any paths it could sue to directly travel that far, did you?" Lilia asked in a fluster.

"No, I can't even find a proper route with the current range of my magic. It also suddenly disappeared on me last time, so I hate to say this, but I think it might be an intangible type. There's no telling where it will pop up." Alaric replied, his face twisted into a scowl.

He then felt the monster disappear again once it had replenished the army of zombies and skeletons that Zareen had decimated.

Thankfully he was able to anticipate its next move and focused his wind magic down the path that Aurelia was holding down. As he expected, the monster had appeared in this direction.

When he announced its current location, Lilia asked him to hold down her corridor and rushed off towards the monster that was the source of their problems.

With a wedge-shaped mana barrier in front of her, Lilia bulldozed her way through the zombie and skeleton horde.

Thanks to her immense strength stat, she was barely slowed down the thousands of weak undead as she pushed them aside.

In less than ten seconds she reached the location of the giant undead creature that was unleashing lesser undead from its mouth.

Laying eyes on it for the first time, Lilia stopped in her tracks due to how grotesque it was.

The large undead monster had a face resembling an angler fish and its jaw unhinged and its mouth opened as wide as its entire body length.

Along with its horrifying head and mouth, the creature possessed a malnourished looking humanoid body that had six arms and legs that ended in webbed feet and hands.

Its skin was a sickly pale, rotting in certain places, and clung tightly to its bones.

Honestly Lilia was seriously unnerved by the monster's appearance and the unbelievably putrid smell coming from its body.

Some morbid curiosity of hers wanted to know what this thing was, but for the most part she was thankful that she did not possess the creature appraisal skill so that she could not look at its status even if she wanted to.

Eventually she was forced out of her daze when zombies and skeletons began clambering over each other to reach over her mana barrier.

"Out of my way!"

Punching forward with an unbelievable amount of power, Lilia blew away all of the zombies and skeletons in front of her and opened up a path to the monster that was spawning them.

"Force Cannon."

Again, firing her tier two spell, she aimed to destroy or at least heavily inure the monster in one attack.

Yet, before her magic connected, the repulsive monster vanished from sight.

In her hast Lilia had forgotten Alaric's suspicion that this create could turn intangible.

"Still, I was forced to practice learning how to deal with this type of monster."

Naturally Marcus had trained with Lilia and gotten her used to fighting against foes that could become immaterial just like him.

Lilia quickly channeled spiritual energy into her eyes and looked around for the undead monster, expecting it to try and launch a sneak attack on her.

Except, what she saw instead was the foul creature running away.

Instead of facing her, it was halfway through passing through a wall and escaping.

"Like I'll let you." Lilia said, leaping towards where the intangible monster had just disappeared.

With one quick motion she slammed her gauntleted hands into the wall and used her earth magic to open it up. She figured that a little damage to the sewer system would be acceptable so long as she eliminated such a threatening undead.

Suddenly having its cover pulled away from it, the intangible monster moved to phase into eh ground instead, but it was too late. Lilia had control of the area and was not going to let it slip away.

"Force Wave."

Not wanting to leave anything to chance, Lilia cast a tier four spell and imbued it with spiritual energy.

The wide blast of force impacted the undead monster, and its form was quickly ripped apart. While its ability to nearly infinitely create lesser undead was impressive, its own capabilities were extremely low for its relatively high level of fifty-one.

After her magic had run its course, the creature was destroyed and had only left behind a magic core to prove that it had ever existed.

As for the zombies and skeletons it had spawned, they remained even now that their creator was gone. Still, it would be a simple matter for Lilia, Alaric, Aurelia and Zareen to clean them up.

"You think we're going to get in trouble for this?" Alaric asked, looking at the damage Lilia had caused with her final attack.

Not only had she rearranged some of the walls and a section of the floor with earth magic, but her Force Wave spell had done some significant damage to the surroundings.

"This was unavoidable collateral damage. Plus, I should be able to put it back to relatively what it was before."

Lilia sounded skeptical of her ability to cover up the damage she had caused, but with her earth magic she was able to at least close off the large holes she had made and put things back into the general shape they had been. Though, the structural integrity of the area had definitely taken a hit.

Once she had finished cleaning up the destruction she had caused, Lilia as party leader declared that it was time to head back. If they continued exploring, they would only have another half hour before it was time to leave anyway.

Unfortunately, the denizens of the sewers had other ideas. Not once in all of the years since the city became a necropolis had they allowed a single living person to return to the surface after entering their domain. And they were not about to allow their record to be broken today.
