Reborn As A Ghost: Time To Build My Undead Army!

-----

"GRUOOOHHHHHH…!"

An enormous Monster stood before our path, the creature covered most of the swamp, and its five heads looked at us with its ten eyes. The monster had four legs and a long tail, while having five heads. It was wingless yet it really looked like a very fat four-legged dragon.

Each head resembled that of a snake, with equally long necks and sharp fangs filled with deadly poison. The beast looked quite literally ready to bring destruction to this entire Dungeon. Whoever this Dungeon Core is, it is really quite insane to ask us to beat something like this on our own…

Well, of course, that would be if we were any weaker than now.

[Five Headed Tyrant Hydra: Lv89] [Rank: A+++] [Status: Furious, Hungry]

[Description]: A monstrous aberration that was mistakenly summoned by the Demon Core due to a Mana overdrive decades ago. It was uncontrollable and enormously strong and devastated any monster it found. The Dungeon Core sealed this beast to contain it, but sealing it away drained more Mana than it should. Now, the Dungeon Core has freed this monster, hoping for someone strong enough to defeat it.

It has five powerful heads which can regenerate almost instantly. The power to unleash a deadly venom breath, fire breath, wind breath, ice breath, and darkness breath, and insane defenses with its draconic scales. However, it is extremely sluggish and cannot move that quickly.

Weakness: Behind the five heads there's its actual brain, destroy the scales and reach its brain, destroying it would stop its regeneration and the beast will die.

[Skills]: [Draconic Magic Reflecting Scales] [Giant Body] [High Speed Super Regeneration] [Venomous Snake Fangs] [Enormous Crushing Jaws] [Poison Breath] [Fire Breath] [Ice Breath] [Storm Breath] [Darkness Breath] […]

Oh, what is this?! I can see weaknesses now?!

This is new! And pretty good as well!

"GRUOOOOHHH!"

"GROOOARRRR!"

"RAAAAARRRR!"

"GROOOOORR!"

"GRYYYARRR!"

All five heads roared differently, yet all their roars mixed together into a nightmarish roar that echoed across the entire floor of the dungeon. We made sure nobody was left in here, so we were just us and the boss.

"Everyone, its actual brain is behind its five heads, right over its back. Aim there and try to destroy its spine and brain, that's where all's its power coming from. It's also slow so don't worry about trying to overspeed it." I told everyone.

"Oh, so you can see its weaknesses?" Asked Lucifer in surprise. "Amazing! Very well then… This is going to be fun! Been a while since I've gone all out!"

"Heh, so that's it…" Brunhild smiled. "Lucifer, Maria, let's go charge forward and aim at the brain, everyone else could attack from a distance, and keep the five heads busy?"

"Sounds like a plan." Emeraldine nodded.

"Huh?! I want to charge forward as well!" Said Partner.

"How about you slice its head to entertain it?" I asked her. "You can drink as much blood as you can from it."

"Oooh! Now that sounds interesting!" Partner smiled. Her Blood Aura surged around her as it shaped into a swarm of bats made of blood, lifting her off the ground. Her two spears shining brightly with an evil aura from within.

"Root, stay with us as well, I've got an idea about how we can use your help." I said.

"Got it!" Root transformed into his Spirit form again as it was just easier to move around, especially giving him the ability to fly.

"Then let's do this!" I said with a smile.

With Lucifer, Brunhild, and Root, we rushed forward towards the Hydra, who was slowly walking across the swamp while inspecting for any snacks to eat. If it has been sealed for so long, it was probably very hungry.

"GGRRRRRHHH!"

The beast's five eyes easily noticed our presence approaching from the skies above, as its five heads opened their jaws in an instant, a multi-elemental breath attack quickly engulfed all of us!

BOOOOOOOMMMMM!!!

However, a combination of my Abyssal Barrier and Lucifer and Brunhild's Draconic Arts named [Dragon Scale Shield] combined together into an enormous shield that easily protected us from the explosion of elements.

"GROOARRRR!"

The Hydra lost its shit as it saw us being untouched, unleashing several more breath attacks, never ending storms of fire, winds, darkness, poison, and ice reached us, as we flew around and tried to reach its back.

The barriers we erected constantly shattered into pieces, as we made our way into the Hydra's back. The bastard was able to easily dislocate its own neck and shoot breaths at us even on its back. And its scales got in our way. My magic wasn't easily piercing through them as they had Magic Reflection abilities, over half of my magic power was reflected when they hit them.

I guess magic reflectors are really a pain, is this common in high ranked monsters? Agh, maybe I could go more all out if this thing wasn't attacking us constantly!

"Here we goooo! Vampiric Arts: [Blood Frenzy]!"

Suddenly, a flash of red light emerged across the skies. Two spears sliced through the Hydra's heads, all five of them at the same time!

SLAAAASH! SLAAAAASH!!!

It was Partner! She was overflowing with red energy, this was the power of her Vampiric Art [Blood Frenzy] that made her go insane like a berserk, while sacrificing her HP as well to drastically boost her stats. The more she sacrificed, the stronger she grew.

Well, she had always been the reckless type of fighter, but this was a rather ultimate move. She'll be all hungry later, I bet.

"GRYYYYAAAGGGH!"

The Hydra agonizingly cried. Its five heads gone! It should had died like that, usually myths go by that rule. But this world had RPG game mechanics, so its HP was still at around 90%! And to make things worse, five more heads began to emerge.

"Gahahahaha! So much blood!"

However, Partner was sure enjoying herself, she was absorbing all the blood coming from the sliced necks before they regenerated, drinking it and then gathering it above the tip of her spears.

"Blood Magic: [Crimson Moon]!"
