Reincarnated as a Son of the Sword Saint and the Sage

Our attacks was effective against the lizard. But it's still not enough to reach the regeneration threshold of its Infinite Regeneration. We've been fighting the lizard for minutes and try any types of attacks on it.

"Sword Wave!"

"Electrocution!"

I slashed my flaming sword and released a fast and sharp wave of blue flame towards the approaching Indestructible Lizard. After being cleaved snout to tail, the lizard was toasted by my Sister's Level 5 Lightning Magic spell.

The two halves linked together and merge. The burned skin restored to its gray hue and the lizard continued its charge to me. I levitated myself fifty foot above from where I was standing and casted a Level 8 Earth Magic spell below it.

"Rupture!"

The earth below the lizard's track shook and cracked. The ground split in half and the one of the limbs of the lizard fell off unto the crack. The fissure opened wider and longer until it reached the width of ten meters at the center.

The lizard held on the edge but the earth immediately crumbled due to its weight. With nothing to hold on, the lizard fell off until it sandwiched between the narrowed depth of twenty meters.

"Gravity Field."

Using a Level 5 Force Magic spell, I increased the gravitational pull of the rupture's area by tenfold. The lizard sense the sudden increase of its weight. It tried to resist the pull but it make its body pinned even deeper inside the fissure.

"Your turn, Sis!"

"Level 8 Lightning Strike!"

Sister raised its dazzling katana to the cloudless blue sky. A large golden magic circle suddenly appeared a kilometer above the ground. A second later, a lightning bolt flashed from magic circle at speed of light.

With her Blue Lightning still activated, the lightning released had a bluish-white hue and struck directly at the pinned lizard.

"Okay."

With a clap of my hands, the two plates converged in a slow manner. The fallen trees inside the rupture make a snapping sound as the earth collides. The lizard didn't move an inch as it let the earth crushed its scorched body.

"Soil Compaction. Soil Reinforcement."

After the rupture had closed, I casted two Level 2 Earth Magic spells to the ground. The earth's level above the closed rupture lowered by few inches. Then the earth hardened and changed its hue to dark terracotta. With that, the lizard has been buried twenty meters below.

"This will buy us some time. Let's make a plan while we restoring our mana and stamina."

"Do you have a plan?"

"I have several… but I am not certain of its effectiveness…"

"We won't find out unless we try it."

"Yeah, you're right. I want to try something so here's my plan…"

"Hmm… Uh huh…"

I whispered my plans to my sister's ears. I explained her each of the plans and its detailed execution. We make strategies on how to defeat the lizard in all the ways we knew.

"It's about to surface."

We discussed the plans for a few minutes and the hardened earth drew lines. With a thunderous noise, the lizard finally resurfaced to the ground headfirst violently.

Claws on the brick-like soil, the lizard raised its massive cursed body slowly to the ground. Making a perfect subterranean entrance.

"Are you ready, Sis?"

"Of course, Raphael. I am always ready."

"Then, execute Plan A."

"Blue Lightning!"

Sister clad herself with flickering lightning of bluish-white hue once again. She lunged herself towards the lizard surpassing the speed of sound, wielding a blue blade in her right.

"Folded Slash."

Sister used a Level 6 Sword technique and slashed her katana seven times in a second. She sliced off each its limbs, severed its tail, cleaved its waist, and decapitated its head. Sister parried each parts after slicing and scattered it to several different directions.

"Ice Coffin."

After the sliced lizard parts bounced off the ground, I immediately casted a Level 7 Water Magic before the parts get merge. The chopped parts instantly turned frigid and turned to a solid ice cube.

"Now then, Inventory."

I tried to store the ice cubes into my Inventory but it didn't work. I didn't have to think deep of how it rendered useless and came up into a single conclusion.

"Even the severed part is alive?"

Then, the ice cubes began to smoke. The interior of the cubes began to melt and severed parts started to move a muscle. The water inside the ice boiled and the ice make a cracking sound.

(It's colder than liquid nitrogen, you know?)

The ice shattered like a glass and the contents poured out of it. The Indestructible Lizard's Extra Skill: Cursed Body melted the ice. With the assistance of Acid Magic, it hasten the melting speed of the solid ice.

After escaping from the freezing prison, six chopped parts flew at high speed to the torso, the biggest chunk. The severed parts connects with the torso in unison and a brand new lizard manifest.

"It's going offensive now."

Being completely restored once more, the lizard channeled huge amount of mana throughout its entire body. Black fog excreted from its body and the nearby plants and trees withered upon taking contact on it.

"Stay away from it, Sis! It's the Level 6 Dark Magic: Life Absorption."

"You save me there, Raphael." Sister leaped towards after hearing my warning.

Some Dark Magic spells were prohibited to practice and branded as Forbidden Magic. Those spells were restricted due to their effects to the victim and the user himself. One of those was the Life Absorption.

It is a spell that unconditionally absorb the life force of the living things nearby to grant the user great sustainability. Even if a person had a resistance to magic, it still inflicts few damage unless the person had a Elemental Magic Nullification, like Mom.

"Looks like we need to fight from range until we drained its mana."

"Let's do. Give me a weapon, Raphael. I want to conserve my mana." she ordered as she sheathed back her katana.

"Here." I withdraw an ebony longbow and a quiver loaded with twenty-four arrows of same ebony material.

The bow and the shaft was made out of Black Treant's wood, string of Vermin Kaiser's metallic thread, quiver of Ram Bull's black leather, arrowheads of obsidian, and plumes of Thunderbird. In other words, the whole set was as black as her hair.

She took an arrow and pulled the black string. She endowed the shaft with a little lightning and the arrowhead with wind. Aiming at the ominous lizard, she released the string.

The durability and flexibility of the bow made the black arrow flew above sonic speed. The magic endowed helps the arrow to spin faster and inflict burns and paralysis.

The obsidian effortlessly penetrated the lizard's head and popped like a watermelon. She repeated the process three more times in just a second, aiming the chest and front limbs.

"Okay, Plan B! Sacred Light! Water Prison!"

After Sister damage its fronts, still regenerating, I casted a Level 9 Light Magic on myself. It's a spell that imbued my next magic spells with Light Attribute. Using the Level 3 Water Prison, I trapping the lizard by containing it inside huge sphere of water.

"Gwuuppp!"

The fully restored lizard gurgling inside the water, not from drowning, it had an invalidation in suffocation. The lizard struggling because of the attribute in the water, the Light.

The holy water continually damaging its Cursed Body, making the water polluted but gradually get purified by the water. The ominous aura of the Life Absorption dispelled after the water blocked its source.

Struggling inside the holy water, the lizard released greenish liquid from its mouth. The liquid then spread throughout the water until the water prison had a tint of green. The lizard poured a large amount of mana and the water started to boil. And I knew what magic it is.

"Acid Burst incoming! Take cover!" we immediately hid ourselves behind the nearby tree.

As if reaching its limit, the huge ball of acid, my former Holy Water Prison, exploded like a water balloon. Tens of thousands of rays of scalding acid scattered at all directions.

The blast reached for hundreds of meters. After the initial explosion, rain of acid precipitated and bathed the area with its corrosive droplets. All flora in the area smoked and slowly withered upon catching the needle-like rays of acid.

"Seems like Plan B doesn't work. At least we managed to cancel its Life Absorption. Are you ready to execute the Plan C, Sis?" I asked leaning my back against a wide tree trunk.

"I am not sure if I can do it now. But I will give my all." she clenched her right fist still have bow in her left.

"That's my sister for you, I know you can do it. Not only you are her best student, but you are her daughter before all."

"That's motivate me. Now I can feel that I will be able to do it."

Following the shower of acidic drops, we showed ourselves to the lizard. The lizard just standing over there and preparing its next attack.

"Are you ready, Sis?"

"I have prepared myself, Raphael."

"Then, let's execute Plan C, the Double Purple."
