Reincarnated as a Son of the Sword Saint and the Sage

A few weeks before our close season, my sister and I managed to defeat the 50th Floor Domain Guardian of an unconquered dungeon. Our next goal is to overcome the boss of the 60th Floor.

Although we've reached that far, and the risk had been raised significantly, Sister still don't want our parents' assistance for conquering the dungeon. Not until we at least reach 70th Floor, if there's one after the 60th.

Since we don't know what lies behind the doors of the 60th Floor Guardian Room yet, we have to strengthen ourselves by levelling up first. We had the monsters of 51st to 59th Floors as our source of EXP.

After we bathe ourselves with the density and breeze of the Forest Floors, we have to endure the droughty and searing heat of the desolated and barren Desert Floors.

Like the name implied, those floors were filled nothing but sand. Scorching and arid white desert sands. Not a single plant or even a cactus erected on those floors. Desert Floors had an area of six kilometers radius with three kilometer high black walls surrounding it.

The monsters on those floors were diverse. Flying, crawling, walking, slithering, etc. The deeper the floor, the more powerful the monsters. Desert Floors have monsters starting from Level 201 up to the strength of Level 359.

Desert Floors provides more EXP than our current hunting grounds inside the forest, which had the average of around Level 300. Since these unlimited monsters were enclosed by the sky high dungeon walls, we were able to accumulate dense amount of EXP compared in a vast forest.

Not only we increased our Levels and stats, we also increased the intensity of our mock battles with mothers to improve our proficiency with our skills and have more experience in battles.

Even though it just a mock battle, our opponents were the continent's more powerful couple. A single clash of Sister's and Mother's blade caused winds to run amok. While an exchange of spells between me and Mom could change the terrain.

They didn't even used their Ultra Skill, Divine Sword Art and World Magic, while fighting us but the damage was already that destructive. That's why we've been doing battles inside the dense and fertile Great Forest of Darkness to prevent collateral damage. We don't mind if we caught some monsters since they're levelling us up.

It doesn't matter how much damage we made in the forest as long as we fought somewhere far from adventurers' hunting grounds. Since it's the Great Forest of Darkness we're talking about, forest will heal itself at great pace.

We keep strengthening our bodies and improving our skill for a long period. So long that we missed the opportunity to fight or even fathom the identity of the 60th Floor Guardian before the close season.

By the way, Griffith stayed in the plains where the dungeon gate stood off. She experienced countless winters in the forest so I know she will be fine. Our mothers still don't know a thing about her.

"What are you doing?"

"I've been trying out some skills that I rarely used. You can see why, right?"

"Yeah. You can't let anybody see that."

I answered her question as I am showing her my scaled arm.

With nothing to do, I've been experimenting the new Skills that I acquired during the dungeon conquest. Also skills that I rarely use to, due to it's inconvenience in battles, and discomfort in the body while using it.

Right now, in the middle of transition of winter and spring, at our mansion's workshop on the third floor, I am using one of the Racial Skill of dragon-type monsters, Dragon Scales.

It's a skill that let me grown sapphire-blue scales like of a dragon to any part of my body. By the way, I acquired it after killing my first A-ranked Wyrm, a wingless, limbless serpentine dragon.

"It feels weird, like wearing a thin, but very durable metal gauntlet. I feel that I can smash boulders barehand." I proclaimed while punching the air.

Dragon Scales not only for defenses, like tolerating physical and magical damages, but also for increasing the damage output of ones body techniques.

With protected fist, one can punch without worrying about the impact. But it also has its limits. Like a fast and power swipe of sharp and durable blade.

"Dragon Scales is not the only one that I can just expose. Look at this."

I did some few hand signs with my deep blue scaled hands before taking a long breath.

Swoosh.

After talking enough air, I released it in form of flames. Ignited the embers in the fireplace that had been giving warmth of this room. Seeing the charcoals lit, I immediately turned off the skill.

"Did you just shoot fire from your mouth? Is that a dragon's skill?"

"Yes. It's the dragon's Breath Attack."

"I knew it."

Breath Attack is one of the dragon's signature move. It's a skill that shoots off the attributed breathes, not just fire. The attributes that the Breath Attack could do, based on my experiments, were fire, frost, lightning, wind, and fog, either poisonous, misty or miasmatic.

By the way, the hand signs wasn't particularly necessary. I just did it to look like a fire-style user shinobi.

"It would be weird if I just spit out flames from my mouth."

"Yeah. I find it out of ordinary, too. What's the reason of you summoning me here?"

"About that… I have something important to tell you in private."

"Based on your behaviours earlier, it's about your skills, right?"

"Yeah, you're right. As sharp as ever, my sister. Let's take a seat first to warm ourselves."

We sat on our couch, faced each other with a glass table between. We can feel the heat of the fireplace for us positioned in front of it.

"What do you want to talk about?"

"You remember the 50th Floor Guardian, the Abyss Slime, right?"

"That transforming slime? Of course I remembered it. Don't tell me it's about its Skill?"

"Yes. Even since I acquired its Unique Skill Organic Domination, I've been conducting experiments with it."

I called my sister here in the soundproof workshop to inform her of my latest discoveries on the Organic Domination for the last month.

"Organic Domination doesn't only take the form of what the skill absorbed, but also analyzed the components of it up to molecular level."

"What does it mean?"

"Give me a strand of your hair."

Sister plucked a piece of her hair then handed it over me. In front of her sharp stare, her hair slowly ingesting into my palm. When the hair fully disappeared on my palm, I begun to explain her the details.

"Using a subskill called Biological Analysis, I am able to break down the information contained within a single strand of your hair. In my previous world, there's a forensic analysis called DNA testing. It's a test to verify the biological relationship between two individuals."

"So you can determine the relativity between two people by analyzing the samples, huh. I already knew the results but what's our rate of being siblings?"

"Based on the test, we are 100% full siblings, with the same pair of parents."

"Is that so? It's good then."

(Hmm? What's that? Lemme tease her a little.)

"Oho. Why do I hear disappointment in your words? Are you not satisfied with the results?"

"I-its just your imagination." she refuted as she averted her gaze.

In these recent months, me and my sister has been more intimate with each other. To the point where Sophia considered Sister as her rival. I don't know what Sister thinks but for me, I considered our relationship as platonic.

"I made a modification in my body using the True Transformation subskill. Can you guess the changes in me?"

"Hmm…"

Sister scanned my body using her amethyst gaze with fingers under her chin. She widened her eyes when she ultimately noticed something.

"Wait, why your mana flow so fast throughout your body? Not only that, it's so stable that you can run it even in sleep."

"Hehe. Since I can biologically copy the traits of the monsters I've absorbed, I changed the qualities of my mana veins like that of a Dragon."

"…"

My dumbfounded sister fell into silence after hearing my nonchalant explanation. Well, it would be shocking to know a person with monstrous capabilities.

Dragons are S-ranked monsters that had high physical strength, toughness, and magical abilities. They were quadrupedal monster with majestic bat-like wings and tough skin under the hard lustrous scales.

They are wild creatures that ravage villages and caused catastrophic damages. Due to their high quality materials and wild behaviors, they were the number one priority to subjugate in the Adventurers' Guild.

"But that's not the revelation that got me the most. It's about the one that I just discovered a few days ago."

"That's not it?"

Now that we're done with the first topic, I move to the next one. It's the most important part of this discussion.

"When I was experimenting the Unique Skill, I tried to analyze and copy the Abyss Slime. But the results really surprised me. As I am copying it, four Skill added to my Extra Skills category. Infinite Regeneration, Acid Body, Fragmentization, and Crystalization. All of it were the Racial Skills of the Abyss Slime."

"Wait a minute. If that Skill can copy the racial abilities of a monster, it means that you can also…"

"Yes. All I need is to get a hand of their part."
