Reincarnated as a Son of the Sword Saint and the Sage

"Let's go, Raphael."

At my sister's signal, we rushed towards the Abyss Slime in a form of a Goblin. With naked blade grasped by our right, we slashed it on the standing goblin. Sister decapitated its head and I cleaved its waist in half.

"As expected, physical attacks won't work."

We ceased our feet and looked back at the goblin, still in one piece. The slices had been already closed and healed and the goblin stand as if nothing happened.

"Playtime is over, you filth. Purple Lightning! Lightning Blade!"

"Infernal Flames! Thermal Blade!"

As Sister announced that, we unleashed our magical scorching blades. Purplish-white dazzling and blazing lights enveloped our naked swords. Our amethyst eyes glowed pale purple like the shade of the lighting streaks of the Attribute Armor enveloping our bodies.

Whoosh.

"Giii?!"

Enhanced by lightning cloak, we dashed towards the goblin at tremendous speed like there's no future. Sensing the dangerous approach, the goblin reflexively waved its left arm and draw an arc of black corrosive slime.

We avoided the acidic black sludge by doing a sharp ninety degree turn. I turned to the left and so Sister the opposite. Then we shifted our tracks and did a U-turn to launch at the goblin again.

Being attacked at both sides, the goblin opened both its palm and activate an Acid Magic spell. Multiple greenish liquid in a form of lance conjured surrounding the goblin and fired it at all directions in bullet speed.

Hizzzzzz.

As soon as the lance met my flaming blade, it instantly evaporated due to its ridiculously high temperature. The collision of the Level 4 Acid Spear and my Sanguine Lotus made sizzling sounds like hot coal extinguished by water.

Realizing the uselessness of its attacks, the goblin poured large amount of mana inside its body and prisoned itself inside a massive sphere of lime juice.

"?! Get back, Sis! It's its maximum Acid Sphere powered by Steel Corrosion spell!"

"Hiih."

The goblin inside the sphere smug seeing the effectiveness of its defense. It's annoying face is so irritating that I wanted to punch its face a thousand of times.

The goblin surrounded itself with a massive ball of acid. Level 5 Acid Sphere is a offensive spell. Since Abyss Slime can invalidate corrosion, it can also be used for defense.

But the problem was the Level 8 Steel Corrosion spell. Just as the name implied, it was a spell that makes the next Acid Magic spells more acidic to the point where it can corrode even the noble mithrill steel.

Even though our blades can nullify the acid, our bare skin and gears cannot. If we just carelessly attack it, the sphere would crumble and spill its contents all around the room.

"Then we have to attack it remotely."

"You mean that? If that's what you meant, I'm ready for it."

"We'll remove that annoying smug of yours."

"Hihihi."

Sister suggested to execute a certain spell. The goblin just giggle at us full of oneself as if saying 'If you can'.

We leaped back for several dozen of meters to avoid the spilling acid in the process. To prevent the collision of our spells, we distanced ourselves from each other, around twenty meters.

We one by one turned off the Lightning of Attribute Armor and deactivate our magic swords to reserve our decreasing mana. Before I cast the spell, I have to increase its damage first.

"Blue Lightning."

I cast as we pointed my blade to the target. Because I can't activate the Purple Lightning, I casted an inferior version of it.

And then…

""Dragon Lightning!""

Upon casting a Lightning Magic spell, massive amount of lightning-filled mana release from our body. It clustered together then begun to materialize and take the form of a sparkling dragon, a Chinese dragon to be exact.

"Let's sauté this goblin in its own lard. Charge!"

On her lead, we raced our own electric dragons towards the goblin, which is still inside its acid asylum.

"Giii?!"

The goblin perceived the danger of the rushing dragons and tried to defend itself, but alas, my bluish-white writhing dragon strikes first.

"Gaaaa!!!"

The dragon of lightning passed through the liquid and electrified the goblin, but wasn't enough to dispel the acid. After a second, still damaged from the previous attack, another dragon electrified the goblin. But unlike before, this purplish-white dragon had higher voltage and temperature than mine.

"Gwaaahhh!!!" That was the loudest cry that we heard this day.

My sister's lilac dragon deals the most damage. Due to its soul damaging attribute, the dragon managed to interrupt its skills and successfully cancelled the spell.

The Acid Sphere collapse on the floor and spread its contents on it. Inside the steaming hot acid spill, the goblin is on its knees, paralyzed by the dragons

"If you thought it's done, you're absolutely wrong about that."

With the wave of my Sanguine Lotus, my blue shining dragon devoured the helpless monster again. The goblin went into convulsion as if doing a strange dance. The strange thing is that my sister's dragon didn't follow my lead.

"Already out of mana?"

"Activating the Purple Lightning sucks too much mana."

"Here. Take that." I took out a small bottle from my Inventory then threw it at her.

＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿

Mana Potion - a potion that partially restores consumer's mana.

＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿

"Good. All I need is to restore some strength. You better buy me some time."

I nodded at her request and continue to manipulate my Dragon Lightning. She ducked and observe the battle as she is recovering her stamina.

Dragon Lightning is a Level 9 spell and my current most powerful Lightning Magic spell. This spell doesn't stop after it hits its target.

It will stay active and can be freely maneuver as long as there is mana. Sister only lasts a shot due to its lilac aura and insufficient mana reserve. Though she had much more mana than most people because of her absurdly high Level.

I didn't get a moment for the goblin move a muscle and continuously attacking it lopsidedly. After about a dozen of bursting fireworks, the charred goblin finally collapsed flatly to the surface.

I cancelled the Dragon Lightning and the Blue Lightning after the goblin down. But I know it's not finish yet.

After a few seconds, the grilled goblin returned to its former green hue at tremendous rate. The goblin gradually raised its small body then stood up straight. And Sister just came to my side in time.

"I'm ready, Raphael. Let's end it in an instant."

◆◇◆◇◆◇

With those words, two teens wrapped themselves with dazzling flashes of lightning and unleashed their magic swords. Their current appearances lit up the solemn scene and make it move livelier when they begun to move.

Daffodil and lilac streaks of lights filled the entire half-kilometer cubic room as the pair run fast throughout the room. Engaging on the same target, they slashed their own blade in one after another.

"?!"

The goblin couldn't follow the movements of the pair. It were too fast that it didn't realize its both missing lower arms.

When it gazed at its burned amputated arm, the goblin noticed that it decreases its length for every second the goblin stared at it. When it looked the floor where it is standing, inch-thick chunks of burned flesh scattered around the surface.

In other words, the siblings slowly chopped off its arms one at a time. The goblin tried to activate its prided Infinite Regeneration to heal itself but nothing happened.

Upon realizing its fate, the goblin, no, the Abyss Slime fell into despair. With knees on the dark grey stone surface, the monster let the blazing and dazzling blade of purple smite its own pathetic body simultaneously.

The dazzling blade of the girl in monochromatic style flew straight towards the monster's neck, easily decapitating it. The blade cleanly sliced the head that it didn't get separated from the body before it dropped off to the floor.

The waves of shining blades continued to chop the monster into pieces. The burned chopped pieces turned back to its original form, the pitch-black slime, as they lost connection to its main body.

The blades finally ceased when the monster's existence reduced to hundreds of black viscous substances. Same as the feet of the attackers.

"Finish it, Raphael."

Following the girl's words, the boy raised two fingers facing the scattered slimes. He gazed his glowing amethyst eyes left to right before he open his mouth.

"Be my steeping stone. Infernal Fire Arrows."

Hundreds of arrow-shape flames appeared and around the boy. Each were around five-inch long and had Hollywood cerise hue. All of those are Level 2 Fire Arrows enhanced by soul burning Level 10 Infernal Flames.

"Shoot."

After he rotate his hand, the arrows flew straight each of the blobs. Upon contact, the bolts quickly spread out and engulfed the blobs in purple blaze. Few seconds had passed, the Abyss Slime lost its life.

◆◇◆◇◆◇

After the Abyss Slime lost its life, the mass and volume of the small blobs increased. If the blobs merged together, it would have been equivalent to its former pitch-black massive blob.

<Experience fulfilled. You levelled up by 1.>

When I heard the mechanical voice of the system and successfully plundered my desired skill, I extinguished the flames to avoid damaging the slimes further. I've seen potential of it and gonna use it in the future.

"It's dead. Confirmed."

"Right before my mana deplete. Good thing we get rid its acid."

"Yeah. If isn't of that, we would have killed it fast."

We weren't able to get near and finish it immediately with our blades since it was protected by corrosive acid. Because of that, we restricted to only attack it from distance but manage to get rid of its shield then finished it at close combat.

"Sigh. Let's get home after claiming our rewards. We'll decide what we will gonna do next now that the conquest get rocky."

We got home safe and sound after I deposited a bar of orichalcum ingot.
