Amidst the Undead Army, aside from the feeble Skeletons, the flammable Undead, and the slightly stronger Skeleton Knights, there were a threat that had been advancing slowly, mostly because they were incapable of getting here in time.
Their size and physical strength alone put them almost at D Rank in terms of monster strength, where Skeletons and Zombies are F Rank at most and the Skeleton Knights E Rank.
These are… Rotten Giants. Monstrous beings made up of many rotten corpses and bones stitched together through advanced Necromancy. It wouldn't be a lie to say I've fought several of them through my past life, mostly due to confronting many Necromancers through the Galaxy who sought my Vampire Body, which had always seemed to be a high ranked material for Necromancy.
Nonetheless, after being reincarnated in the world of Spirits such as Spiritias, I never thought I would truly see the work of a Necromancer in action, or at least, not so soon. This probably means that despite the difficulties and limitations that Spirits might give to people when they awaken their powers, there must be a large quantity of unknown and powerful enemies out there.
Perhaps even closer to me than I had imagined!
The gigantic Rotten Giant's hand clashed against the walls made of stone we had erected with Eleanora to stop the charge of the Undead, quickly opening the way for dozens of them to sneak inside.
Undead began to groan hungrily as they saw our living flesh, their lifeless eyes showing a ruthless and emotional glint that only made me smile slightly.
"T-That Rotten Giant destroyed our whole strategy!" Eric cried.
"Damn it…!" Chris roared, swinging his staff and unleashing fireballs around him with the help of his spirit. Several Undead that got closer to him began to burn to a crisp, but he had a limited amount of MP, overdoing this would only bring him to more exhaustion.
"Blake! What do we do now?!" Erdrich roared, his body grew a few centimeters larger once more as countless red tattoos emerged over his entire body, until he turned completely red.
Black tattoos quickly began emerging over his red skin as large horns appeared over his forehead, his nails grew into monstrous black claws, which he used to slash the undead and shake away those that tried to climb his big body to overwhelm him.
"Elizabeth! Use that Spell now!" I ordered Elizabeth, but she seemed to hesitate.
"T-That Spell?!" She asked. She had learned a special Skill some time ago after leveling up, which was perfect to exterminate Undead and Demons. "But if I conjure it, Erdrich might get hurt!"
"Don't worry about that, I've already prepared for such a scenario!" I said, giving Erdrich a potion from my pocket. He quickly grabbed it and ate it whole, glass and everything.
Suddenly, a black aura surged from his body.
"What the heck is this?!" He wondered.
"I had assumed there would be a time someone would bring something that could hurt demons very badly. This is a Demon Fortification Potion. It gives you more Demonic Energy to withstand stronger blows. Use it to coat your body and prepare yourself!" I said.
This was a potion I had already drank myself, as I had an eye and an arm which were totally demonic, I had some partial weakness to holy light and other specific spells that dealt large amounts of damage against demons.
This was merely just a spare one I had anyways, I had not thought that far in regards of Erdrich, but it was just for myself. But it is certainly convenient now. I might end up making more in the near future for him.
"Okay then!" Erdrich immediately obeyed my commands as he coated his body with this dark and red aura, and Elizabeth received my thumbs up.
Elizabeth suddenly gathered the large quantities of Mana she possessed within her entire body and then imbuing them into her special Holy Staff, a flash of bright golden light emerged from within her weapon, resembling a miniature star.
"Holy Light Arts: [Exorcism]!"
A wave of pure holy light was unleashed all around us, so powerful it quickly encompassed all of us and the demons within all our vicinity and even far beyond that. The weaker Skeletons and Zombies were turned into ashes in an instant, while the Skeleton Knights only struggled for a bit before disappearing.
The Rotten Giants began to groan in agony, most of their bodies began to burn and turn into ashes, although they were very big so they were resisting quite well. Nonetheless, Elizabeth didn't just conjured it once, but twice.
Another conjuration came right after the first one, the Rotten Giants weakened even more and all the small fry turned into ashes. This was our moment. I rushed forward and unleashed Fireballs imbued with my Blood Ki, Crimson Flames surged, which were not weak to holy light. I used them to finish off the amorphous Rotten Giants one by one by crushing their Spirit Orbs inside of their bodies.
Shaping the Scarlet Flare into arrows, they quickly aimed at the surviving Undead, burning them once and for all.
When the light finally reseeded, everything had become oddly calm, but a tired Elizabeth sighed, falling into the floor while seemingly looking feverish. She had worked hard.
"Elizabeth!" Erdrich ran towards her alongside everybody else, as they looked at her.
"I-I am fine… Just tired." She sighed.
"You overdid it too much this time!" Erika said.
"Blake did you had to force her to do it twice?!" Asked Chris angrily.
"She could barely handle it…" Eric muttered.
"She did it on her own accord, I only asked her to do this once." I said. "She's the reckless one here. But I like that. Well done, Elizabeth."
Unlike everybody else, I head patted her, and smiled back at her.
"I'm glad I could help…" She said with a sweet smile.
