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

—–

In some fictional stories, you might be supposed to defeat a hydra by cutting all of its heads at the same time, right? Well, in this world, there is the concept of HP! No matter how much a monster fights, it won’t die as long as it has HP.

However, due to this, they are also bound to die if the HP goes down to zero. Therefore, we decided to ignore the Hydra’s [Head Regeneration] Skill, which let it instantly regenerate a whole head if it was lost.

So, we decided to slowly drain away all of its HP with a variety of attacks from all around. Meanwhile, this skill didn’t seem to affect the head when it was not cut, so we just had to blast its eyes off!

“RRRAAAA!”

Lucifer used his sharp claws to reach the Hydra’s front head and slashed through its eyes!

“GGRRYSSSSHHAAA!”

However, the Hydra screamed furiously as it bathed Lucifer with several elemental attacks!

BOOM! BOOM! BOOM!

“Damn it…!”

Lucifer lost one of his arms and a wing in the process, so he was forced to pull back. We had no healers here, and I was running low on options. I needed a more penetrative attack! Come on… If I have Supreme Magic, I can do whatever I want with magic, right? Then… I should be able to learn something…! I began to shape pure darkness into a long and pointy form… and then… I launched it!

FLAAAAAASH!

The spear arrow of darkness reached one of the Hydra’s heads and impaled its eyes right away, from left to right, like a skewer!

“GGRYYSSHA…!”

The head cried out in agony as blood began to flow from its enormous wound.

Ding!

[You’ve learned the [Shadow Spear Arrow: Lv1] Skill!]

Oh! It emerged as a skill! This is exactly what I needed! I already had an explosive Dark Sphere and a sharp Dark Gale, so now… I have the piercing Shadow Spear Arrow!

I quickly absorbed more Mana from the Hydra, which had a tremendous pool, before I began to fire Spear Arrows of Shadows in quick succession! Meanwhile, Kuro and Partner continued to attack its limbs until one of them seemingly broke, making the creature trip over!

BOOOMMM!!!

We abused this as we continued to shower it with attacks, and Lucifer roared furiously, jumping over the beast, and using his heavy weight to crush its bones!

“GRRRAAA! YOU DAMN LIZARD!!!”

CLASH! CLASH! CLASH!

“GGRRYYSSSHAA…!”

The Hydra was on its last moments, but I had to kill it quickly before it triggered the [Last Minute Healing] Ability it had! Seriously, this thing is seriously overpowered! Who made it?!

I created a gigantic spear made of shadows, exhausting almost all of my mana and then launching it at the beast’s chest!

FLAAAAASH!

It reached its chest and pierced through its large jewel, making the creature vomit mouthfuls of blood that flowed from each and every head.

“GGRRYYYSSSSHAAAAGGGHH…!”

BOOOM!

The monster gave up at long last, and its health dwindled down to zero!

Ding!

[You have acquired the [Dungeon Conqueror: Lv–] and [Big Game Slayer: Lv–] Title Skills!]

Oh boy… What? How much did I level up? Five times? Damn… And I got two titles out of it!

I glanced at everyone else, and I seemed to be the only one that got them… Hehe… I guess that’s what you get for finishing off the dungeon’s last boss?

“Hahh… How was that thing so hard to kill?” Lucifer breathed a sigh of exhaustion.

Even as an Undead, he was exhausted… Well, we get tired when we use a lot of mana, even as Undead, so it’s understandable.

“Fweehh…” Partner was resting on the ground.

“Mraoo…” Kuro was also exhausted.

Everyone seemed to get a ton of levels too! Kuro reached max level right away, while Partner was just one level from it. Lucifer just barely got to Level 6 as he was so strong, so leveling up was quite troublesome. Our status also healed when we leveled up, so the exhaustion was more like the soul getting lazy. However, we didn’t have time to rest. I forced myself to move and quickly decided to save the entire monster corpse inside my inventory and check it with the drops later.

We didn’t have to relax leisurely. I felt some life signs above. Yeah, since I evolved, I’ve detected “life” as something like a sixth sense. A large group of strong life signs is approaching us from the layers above. I grabbed Lucifer’s arm and stuck it to his body by manipulating phantom forces and using them like glue. It worked pretty well, also with his wing.

Ding!

[You’ve learned the [Undead Healing: Lv1] Skill!]

Eh? Another skill… I guess with this, I can heal everyone else! But the Mana Cost will be painful…

“Anyways, now, let’s get going. I can sense several presences coming down here! We might end up fighting right away, so get prepared for what might come!” I warned everybody.

“Damn it, who else is coming now? Wait… You said there was a town nearby? It could be Adventurers… They found out my dungeon so fast!” Said Lucifer, as we all mounted Kuro before he began to rush upstairs.

We rushed through several floors in a breeze as Kuro had grown superfast after leveling up quite a lot. And within just a few minutes, we had already reached the tenth floor where we finally heard them.

“Why are there no monsters here? So weird…”

“Yeah, we only found some ooze and bug juice around. Did a monster enter and eat everything inside?”

“Wait, if that’s the case, shouldn’t we go back and report this?!”

“Y-You’re right!”

Eh?

The Adventurers suddenly realized that they were being too reckless and rushed upstairs, running back to their town. Well, I guess they weren’t stupid. We reached the surface and dived deep into the Dark Forest without any problems. I guess life doesn’t always have to end in conflicts!
