The Exiled First-born of the Noble house. Rising to the top with the Worthless Skill [Null Poison]

Chapter 420

Trump Card

I wanted to save this until directly fighting Elphas but, in truth, this ex-hero was more dangerous than Elphas herself.

Having judged that, I decided to pull out my trump card, the ability I never used in battle until now.

I had only used it in front of Phillip-san during training, and he had directly told me to not use that skill unless extremely necessary.

He said that a normal person might straight up die if they used this skill but, behind his back, I continued to practice for the day I might have no choice but to use it.

This dangerous skill was——[Mana Rampage]

Until Phillip-san taught me, I didn’t even know how to activate this skill but when I activate this skill, I become capable of absorbing mana straight from the air surrounding me and make it my own.

You might wonder where was the demerit in all that but, [Mana Rampage] was a skill that didn’t stop or rather, couldn’t be stopped no matter what until you had completely run out of mana.

People who used this skill had died in the past as well from it so I guess that’s one demerit as well, and perhaps that’s why it was still a ‘common skill’ and not a unique one.

Chris-san had also been practicing to be able to control his [Suicidal Strike] from completely exhausting him to unconsciousness but…….in the end he too deemed it impossible to deactivate by yourself.

And so I came to the conclusion that perhaps I could use it in tandem with my [Mana Regen] to make it work better.

[Mana Regen] was a passive skill that was always active, which basically raised the rate at which my mana replenished.

I had been practicing in secret hoping that perhaps I could control [Mana Regen] as well and perhaps find a way to save and stock up the mana it regenerates instead.

I also got advice from Chris-san who can control and use multiple skills at the same time so after many, many days of practice, I was finally able to succeed in controlling [Mana Regen].

After activating [Mana Rampage], after the skill deactivates when my mana runs out, I could sue all the mana that I had saved up with [Mana Regen] to replenish myself back to safety, finally allowing me to use [Mana Rampage] in a real battle.

But as the word trump card implies, it really is a skill that can only be used as a last resort, as the amount mana that can be replenished was fairly limited, making any battle that may happen afterwards to be fairly complicated.

And of course, by using the mana around me, the amount of mana that can be replenished gets diminished in the first place as well, so it was best to use against only the last remaining enemy but…….

Seeing the former hero undead casually walk towards me, I decided now was indeed the time to use it.

I breathed in deeply, and then quietly muttered under my breath.

“[Mana Rampage].”

As soon as the skill activated, the mana around began to swirl towards me, and I could feel great strength well up inside my body.

It really feels like I could do anything right now but, I kept my cool and focused on taking down the ex-hero undead first and foremost.

For starters, I tried using a basic magic to test things out.

My fear from before had been blown away, and I was only focused on figuring out how to best defeat this undead.

To first figure out the changes this rampaging mana causes to my spells, I needed to use a basic spell to critically analyzing the differences.

“[Stone Arrow]”

I kneaded the overwhelming mana together, and then started chanting to launch the magic.

Stone arrow would normally be about the size of my fist but, the one I was building in front of me right now was almost as big as the rock used in [Meteor Flame]—-

And then as soon as the chant was over, I fired it straight at the ex-hero undead.

Just like last time, the undead swung his fist to smash the [Stone arrow] but, while he did smash it technically, he failed to fully kill the force behind it and a part of the stone arrow slammed into its head.

It staggered slightly from the impact, and its legs finally stopped moving towards me.

It barely did any damage I think but, what was more important was the fact that I had somehow hit him with a basic magic even though he had easily stopped my advanced magic before.

Even now, the mana around was flowing inside me, and was getting collected within my body.

Seeing the undead stop in its track, I saw it as a chance and began to prepare an advanced level magic.

Even though it was completely under Elphas’ control as an undead, it seemed like the experience of the corpse hadn’t completely disappeared as it broke into a dash the moment I began to chant the advanced spell.

It wanted to kill me before I could fire my magic—–from the fast movements of the undead rushing towards me, I could tell its intentions very clearly so I too calmly changed the spell I was planning to use.

“[Aero Ball]”

I can’t do no-chant advanced spell, so I switched to intermediate magic where I could do abbreviated chants, and then fired the magic at the oncoming undead.

It held up the high quality shield it was equipped with to defend against my [Aero ball] but……

The size of my magic was more akin to a 4 meter wide strong ball of raging winds.

Furthermore, it even enveloped the broken particles of the smashed [Meteor flame] and [stone arrow] within it as well, as a large amount of broken rock fragments also flew at it at a fast speed.

I’m sure the shield was designed to be able to defend against all sorts of attacks but, it was impossible to block an attack that came from all four sides.

The giant [Aero ball] completely swallowed the undead, and the rock fragments turned into sharp blades in the raging winds, as they dealt multiple hits on the undead.

By the time the [Aero Ball] passed through him, and I was able to check on it with my bare eyes, the undead had been chipped from all sides and was currently down on one knee.

Part of its head had also been blown off but, being an undead and all, it was still able to move.

“If possible, I would have loved to fight you when you were alive. Rest in peace.——[Electitonitrus]!”

Talking to the unnamed hero, this time, I activated my advanced magic at him.

A powerful thunderbolt hit his still slightly moving body directly, and then completely erased him with the thunderclap.

He really was strong, and I would not have been able to beat him without my trump card.

If he wasn’t an undead, and was acually fully able to use his own brain, perhaps I wouldn’t have won even after using [Mana rampage]……..

And that’s why I said that I wanted to meet him when he was still alive.

I felt a bit disgusted seeing a once proud warrior and hero raised from his death just to be made to fight even more for some other person’s sake but, I suppressed my emotions to remain calm and turned my focus towards Elphas now.

Most of the scrub undeads she had summoned had also been eviscerated alongside the magic I had fired at the ex-hero undead.

My [Mana Rampage] had run out yet, so while I can still use these super powerful spells, I need to quickly put an end to her as well.

I quickly made a side glance towards Snow to see it still fighting, and completely dominating the Melanchimaera while it continued to dodge the Noble Lich’s magic attacks.

With this pace, Snow will definitely beat those two for sure. So I can go all out against Elphas instead.

A top elite, vs a former scrub.

A fight that I simply could not afford to lose was about to begin.
