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

-----

There were three types of monsters that originally inhabited these caves before they were overrun by the Abyssal Ants and their enormous Nests. Termites as big as these Abyssal Ants, but with metallic body exoskeletons and growing large colorful crystals over their bodies as spikes, Ore Eating Metal Termites. Giant Turtles the size of up to four to five meters with big shells covered on sharp crystals, Crystal Turtles. And then big, tyrannosaurus-like reptiles of the caverns that grew sharp spikes from crystals growing over their bodies, Crystalsaurus!

These were the three kings of this third floor before the Ants ate them all and made their nests all around here. But now such ants were completely exterminated. So obviously, such ants which were an external factor, cannot be summoned, and in fact, the original monsters were finally back!

"SHAAAA!"

The ferocious termites ran forward, immediately spotting us to bite us with their sharp serrated fangs, they even conjured spikes of sharp rocks, using earth magic!

"ROOARR!"

The turtles began spinning on their own shells, rushing rapidly towards us!

"GROOOOAAAARRRGH!"

And the ferocious Crystalsaurus roared angrily, rushing forward, and opening their jaws. As lesser dragons, they had elemental dragon breath attack!

And yes, they were all ferocious A- Rank monsters.

"Let's see what you're made of!" Lucifer roared, moving forward with Brunhild, the two quickly kicked the Termites, crushing them into pieces by their very weight and strength combined.

SPLAAAT!

They splattered over the floor easily.

"Let's see… Magic Bow Arts: [Spiritual Light Arrows]!"

Emeraldine pointed her magic bow at the turtles, firing several arrows made of spiritual light at them.

BOOOM! BOOOM! BOOOM!

The turtles tried to tank the hits, but the arrows easily pierced through their shells, which gained cracks and then exploded into pieces, the turtles died on the spot.

"Let's try out these two new spears! Dual Blood Spear Arts: [Dual Piercing Blood Dragons]!"

Partner rushed forward, unleashing a consecutive attack using both spears at the same time. A wave of blood essence emerged from her spears as the two unleashed powerful and devastating piercing blows against the Crystalsaurus.

CRAAAASSSSSHHH!!!

The enormous blow pierced through their bodies a hundred times. Their mighty scales were nothing against Partner's might. The monsters were defeated on the spot, covered with holes…

And…

"Wait, that's it?" Asked Lucifer.

"I thought A- Rank Monsters… would be stronger than that." Brunhild sighed.

"If you guys don't remember, the ants had many A- Rank members, the knights for example. Their boost was that they had miasma with them so it was tricky to fight them due to the toxicity of the miasma and its ability to reflect most magic damage as well. But normal A- Rank Monsters? They're just not that hard anymore… Alright, let's continue! I'll raise the number to twenty!"

FLASH! FLASH! FLASH! FLASH!

Like that, I continued summoning more and more monsters, slowly rising the amount of numbers I used in each wave of monsters. We were able to defeat them no problem. Already at the beginning they seemed easy, but when I joined the fray to fight directly things became even more easily.

Ultimately, at the last waves, we were being swarmed by hundreds, but easily dealing with them and blowing them all way into shreds using magic and skills of super high level. My battle axe and my magic longsword were amazing too, simple swings of these weapons generated shockwaves of darkness all around, impacting the monsters and slicing them apart.

The morning finally came, and a ridiculous amount of EXP greeted our sight…

Holy shit! I gained twenty fucking levels in a row! And exactly twenty at that! And not only that but I even ended getting two Title Skills out of the entire grind… Man, it was really exhausting though. But at the end it was totally worth it.

-----

[Dragon Slayer: Lv1]

A Title Skill acquired by slaying over a hundred dragon-type monsters. It enhances damage dealt against Dragon-type Monsters by +50%, with an additional +10% with each Skill Level. Additionally, it grant access to a Dragon's Powers such as [Breath Attack], [Dragon Scales], and [Dragon Eyes], which grow in strength with each Skill Level.

-----

[Relentless Hunter: Lv1]

A Special Title Skill awarded to someone that has hunted an exceptionally large amount of monsters through a short amount of time. It enhances all Damage Dealt against Monsters by +20% with an additional +2% with each Skill Level. Additionally, increases Monster EXP and decreases Level Up EXP Requirements based on Skill Level.

Well now this is interesting! I never thought Titles could go this far… And Dragon Slayer gives three Dragon Abilities such as Breath Attack, Dragon Scales, and Dragon Eyes?! That's insane! Meanwhile, Relentless Hunter increases damage to all monsters in general, increases EXP earned and decreases EXP requirements! This is too good to be true…

And just after that whole fight, I feel way stronger. Leveling twenty times in a row really gives a godly amount of strength. Even my physical might has been enhanced.

However, I was the only one currently awake, everyone else was napping. The whole fight was too exhausting for everyone else. However, I could feel they were overflowing with new strength…

"A-Amazing…" Tyr suddenly showed up at my side. "To think you would be able to defeat a thousand of such strong monsters, this method was suicidal for most, but to you and your group, it seemed like a walk in the park…"

"Heh, surprised?" I asked while feeling like acting cocky.
