Reincarnated as a Son of the Sword Saint and the Sage

There is actually an effective way that guarantees results, but Raphael absolutely does not want to do it. The dragon is not after all like his two beloved mothers.

Speaking of the devil, getting rid of its Immortal unique skill is skillfully possible with the available resources he has. For example, the Despoil ability of his Mother's legendary weapon, but only his Mother could utilize that ability.

(If I want to utilize that legendary effect, I have Mother come and fight the dragon herself. But it is too dangerous; she would exhaust herself before the dragon, even with her duo with Mom. To top it all off, it is still unclear if they could survive the lethal attacks of the dragon.)

There's no way Mylene and Claire could have survived the dragon's Bane of Masses, Dragon Blast, barrage of dark magic spells, and the World Magic spell, Atomic Age. And Raphael was not always available to save them.

Even after getting rid of its Immortal, the winner would be decided by the first one to exhaust. Since the dragon has the Auto-MP Recovery, its mana would undoubtedly restore sooner than the pair due to its six digit magical reservoir.

(Another thing is that the possibility of getting rid of the Immortal unique skill is very low.)

Even if Mylene manages to trigger the Despoil effect of her rapier, the seizable skill was set to random, and she needs the luck of the devil to take the desired skill.

The Despoil only takes effect once a day, so a single mistake would officialize their fates.

Aside from that...

(If that happens, I have to expose the existence of the dungeon and the foxes I would be sheltering of. Well, I don't have to mind the things that never happened.)

After thinking for a bit, Raphael came to the conclusion that calling his parents was not necessary. The risk was just too high for them, and that move would put another nail in his coffin.

Even without them, Raphael has to think of a way to disregard the immortality of the black dragon. That's why he has to rely on his novel skill.

(Hey, Akashvani. Do you have an idea of how to get rid of its Immortal? You know, like how you dispelled and canceled its attack?)

<Suggestion. Upon conducting a deep understanding of the Akashic Records—>

(Wait. Akashic Records? Is that a power of yours?)

<Affirmative. Akashic Records is the archive of all the collections of the world's information, whether they are lost in circulation, currently available and unavailable, or yet to exist or create.>

The Akashic Records of the Akashvani ultra skill. An ineffably very concerned ability for someone who desires to broaden their vocabulary about almost everything.

Because of the Akashic Records, Akashvani came up with the solution to repel the dragon's spells and created the very first occurrence of the Ruler of Death ultra skill in the world's archive.

(But why now of all the times?)

<...Failure to receive specific instructions.>

(Tch! Such an NPC!)

Akashic Records is an ability that grants the user access to the world's largest source of unlimited information. But the user has to inquire since Akashvani neither thinks for itself nor makes its own decisions.

(Okay, Akashvani. Show me the way.)

<Affirmative. Upon conducting a deep understanding of the Akashic Records, the integration of following skills: Plunder, Organic Domination, Anti-Skill, Megethoskinesis, One Man Army, Limiter, Kin Command, Blood Life, Auto-MP Recovery, and an addition of 50 SP might be useful. Proceed to execution? Yes / No.>

(Of course, yes.)

As ordered by Raphael, Akashvani took action to deal with the annoying ability of the black dragon. Upon synthesizing the essences of the following skills, the skills were integrated into a new, powerful ultimate power.

With the cost of some skills and Skill Points, Akashvani was able to utilize the powers of two ultra skills, Ultimate Combination and Ultimate Augmentation, and form an ultimate result.

<Successful. The following skills have been integrated into Ultra Skill: Overlord of Sins.>

(That's Akashvani for you!)

After acquiring and grasping an understanding of his new power, Raphael was hyped up and excitedly performed the Ultra Skill with enthusiasm.

First things first, he had to get rid of the dragon's immortality by using a sub-power of the Ultra Skill. But he needs to grasp his target, so he first activates one of the seven abilities of the Ultra Skill.

pαпdα Йᴏνê|,сòМ Still hovering in midair, Raphael stayed in his spot as the dragon radiated like a blue star. The temperature of the dragon was just too much for Raphael's body to take.

Then the dragon suddenly drove itself towards the human, still activating its Burning Effulgence. Raphael flew away and cast some spells as he flew.

"Hydraulic Collapse!"

Upon invoking the name of a Level 9 Water Magic spell, a huge magic circle was called forth. Once the glowing dragon reached the right spot, a heavy stream of water poured down from the magic circle and bathed the dragon.

Hizzzzzz...

Sizzling sounds echoed in the desert as the water evaporated upon making contact with the dragon. But the volume and pressure of water were enough to extinguish the entire dragon and even pin it down to the surface.

"Okay..."

Once the two hundred-meter-wide waterfall ended, Raphael stopped from flying and started to manipulate the bath water. Following the gestures of his hands, the water moved as he willed.

Without waiting for the dragon to stand, the water formed a massive sphere and drowned the dragon within.

"Oceanic Water Prison!" With just a clasp of his right palm, as if trying to squeeze a stress ball, the Level 10 Water Magic spell started taking effect.

In an instant, the two hundred-meter diameter water sphere shrank by half its volume. Being pressed by dozens of kilometers deep of pressure, the body of the black dragon was compressed to a splat, causing the water to turn red.
