Reincarnated as a Son of the Sword Saint and the Sage

Just four months ago, after my sister\'s birthday, she ordered me to level up faster for Mary to live eternally. We appealed to our parents again to make our hunting at least twice a week but they made it trice a week.

We train our bodies during Mondays, Wednesdays and Fridays. Afternoon of Tuesdays, Thursdays and Saturdays are our monster hunting and we do day off on Sundays.

"There are still more approaching, Sis! But this time, a pack of ten Orthrus around Level 200 to 250, led by a Level 360 Cerberus. Estimate Time of Arrival, three minutes."

Using my Omnidirectional Perception, I informed my sister about the incoming pack of demonic dogs as I am cleaving an Ogre head to crouch.

"Copy that! Circular Swipe!"

She responded then rotate her body to revolve her katana and annihilate three Ogres who just entered her attack range. Leaving them vertically sliced into two.

A much larger and obviously stronger superior kind of Ogre, around ten foot in height, is approaching us with intention to kill after seeing his kins getting killed by us. I gestured my right hand into a gun and pointed it to the rushing club wielding Ogre.

"Air Sniper."

A foot diameter green magic circle appeared in front of my fingertip. A fast and sharp sound passed our eyes. Then it followed by a splatting sound as the head of the Ogre bursted like a pomegranate. The headless humanoid monster staggered for a while before it collapsed on the ground.

"Headshot." I said while blowing the non-existent smoke that is released from my finger pistol.

The magic spell that I just casted was a Level 6 Wind Magic spell called Air Sniper. Just as the named implied, it\'s a spell that shoot a fast bullet of wind. From what I observed, it was measured one fifty caliber and had a speed several times faster than sonic speed.

Shooting a bullet of this caliber and speed is a sure kill. Though you have to practice your marksmanship and steel your stance first before casted this spell due to its slow reload rate and high recoil.

Ogres are humanoid carnivorous monsters that are eight foot tall at average. Ogres had skin color ranging from dark brown to maroon and a dull horn at their foreheads. Ogre General, meanwhile, was taller and had two sharp horns.

(They looked like a Japanese Oni, though.)

Using Inventory more frequently made me got better at mastering it. I can now open several Inventory at once and successfully collected all eight Ogres, including the Ogre General. Ogres have tough hides that would make a good leather.

"The dogs will be here any minute." I warned.

"I know. I can detect them now."

Even if you said that, the monsters are still two kilometers from our position. Sister\'s Detection coverage can cover the area up to four kilometer radius. And that was not normal and way beyond veteran scout could reach.

As for me, I have my Unique Skill Omnidirectional Perception. With my current mana reserve, I can cover whooping ten kilometer radius and beyond. If I had to say to myself, it\'s also not normal by any means.

After we wait for a minute, the noise of rumbling earth could be heard behind the woods hundreds of meters away. I readied my newly forged crimson bladed katana as the demon dogs get closer.

I\'ve been killing monsters for years. Too many that it reached four digits in total. Slaying monsters means having their corpse. And most of the corpse had blood splurting from it.

Since there are some inedible monsters resided inside my Inventory, mountain of amount of it were wasted. Then an idea came up in my mind of how to make use of those.

One day, when I was surfing on a social media site, I happened to stroll an interesting meme. The meme claimed that you can make an iron sword out of blood of thousands of people. And I took that personally.

Instead of human blood, I used the blood from the unused corpse in my storage. Using Alchemy, I extracted the iron content from the monster\'s blood, which was still in my Inventory.

The monsters had mana in their body. That body includes the blood flowing in their veins. Being drenched in mana for years, it also affects the quality of the blood. Some blood had different taste, viscosity, molecular content and color.

After I extracted all of the iron from thousands of monsters\' corpse, I used Alchemy again to take it form of an ingot. What unfolded in my eyes was not an ingot of a typical iron steel, but the personification of crimson red blood in a form of an ingot.

When I used Analysis on the blood red ingot, it was called Blood Steel. It said that it was as durable and as conductive as an adamantite. Which means it had the same quality as the most durable metal known to mankind.

I used the ingot and made myself a katana just like my sister. It is almost identical to my sister except for the metal used, blade length and the tsuba design. I made a katana myself because I want to become a storm that is approaching.

"Are you ready, Sis?"

"I am always ready, Raphael."

Then the alpha of the pack came out from behind the shadows of the trees. It stopped its feet from running and stared at us menacingly.

"Grrrrrrr…"

The quadrupedal monster had pitch-black furs, bloodshot eyes, drooling mount with sharp fangs and teeth, and standing at seven foot. The most distinct trait of it was it had three heads, which was the unique classification of a Cerberus.

"Grrrr…" the Cerberus growled as it\'s five foot tall two-headed Orthrus cronies one by one came out from the woods.

"Would you like to take the Cerberus, Sis?"

"Of course I like to."

"Then, I\'ll be taking six Orthrus." then we charge to the dogs after splitting choosing our targets.

"Woof!"

The pack also lunged at us after we showed our hostility. The Orthruses charged at us first while the Cerberus stayed behind.

Everytime an Orthrus reached our attack range, we instantly slash our swords killing a hound on the process.

(One.)

I swing my sword horizontally and amputated the heads of the first Orthrus.

(Two.)

Swiped the sword diagonally and cleanly cleaved the second Orthrus.

(Three. Four)

I trust my sword and impaled the heart of the third dog. I pulled my sword immediately, rotate my body clockwise, swing my sword gracefully, and double beheaded the fourth Orthrus.

(Five.)

I stopped my feet and opened my palm. I silently casted Level 5 Water Magic: Icicle Spear and impaled the heart of the fifth dog.

As for my last kill, I held the handle of my katana with both hands and raised it overhead. Upon reaching my range, I swing my blade downward and activated a Level 2 Sword Art technique.

"Vertical Slash!"

I slash my sword to the jumping Orthrus. The deep red hue of my blade passed the jet-black fur of the hound and hit the skin. My blade penetrate the flesh between the heads of the Orthrus, continued until it hits its heart then the magic crystal. Slice the innards all the way to the rear.

My overwhelming STR stats swung my blade at incredible speed that it released a shockwave that sliced the earth. If I used Sword Wave, it would caused greater damage to the surroundings and could result to collateral damage.

"And six."

The black body of the Orthrus cleanly sliced into two and drop off to the earth. I don\'t need to swing my sword to get rid of the blood like I usually do. The sword itself will absorb the blood due to its Blood Life effects.

<Experience fulfilled. You levelled up by 1.>

I looked at the path made by my sister to see four Orthrus cleaved in half like what I did to my last kill. She is currently facing a D-ranked monster Hellhound and an Orthrus, the Cerberus is not to be seen. But it was actually the Cerberus from before. It\'s just using its Racial Skill called Split Body.

The Cerberus launched itself to my sister just to lose one of its head. The head slowly grew its size and form limbs then a Hellhound is born.

The severed head of a Cerberus will take form and spawn a Hellhound, up to three spawns, including the main body. Each Hellhound spawn will take 25% of the main body\'s Level, living the main body with 50% stat as a Hellhound.

The main body can absorb the spawns again and regain its true strength. If beheaded all heads at once, four new individual Hellhounds will be born with 25% stat each, losing its main body.

The two spawn Hellhounds charged to my standing sister. Both of them lose their heads in unison from a single slash of my sister\'s sword. She then dashed towards the dumbfounded former Cerberus and its head is now flying in the air.

I remotely collect all of the dogs\' corpse inside my Inventory. Even though its meat taste so bad and could caused curse and diseases due to its cursed body, its jet-black fur was a fine material for fashion and fetch a good price.

"Isn\'t it strange to encounter these monsters in these area?" I pondered as I collect sister\'s kill while approaching her.

"Yeah, it\'s strange. It seems like they were desperately trying to run from something…"

"It seems. New wave of monsters are coming from the deeps. Estimate around a hundred individuals, ranging from Level 200 to 400."

"Now it turns into a monster stampede. Let\'s take the strong ones are leave the rest to the adventurers nearby."

"Affirmative, Sis. Let\'s find the source of this stampede."

We are currently in an area where mostly monsters of D-rank roam. Encountering a group of C-ranked Ogres with a B-ranked Ogre General in this area is surely strange. But a pack of C-ranked Orthrus led by a B-ranked Cerberus are making it more stranger.

We march deeper into the forest and kill strong monsters on the process. From the behavior of the monsters, they look like evacuating to safer place away from the source of this stampede.

If there are A-ranked monsters included in the stampede, the cause of this stampede must be a thing that is more than these monsters.
