A boulder hurled through the skies.

The closer it came, the larger it grew. The blue skies and clouds were hidden behind the giant stone flying my way. The boulder grew bigger and bigger, and eventually, I could see the moss and trees growing on it.

Shirley screamed from the side.

It was not a boulder but a whole chunk of a mountain. I chuckled as I swung my sword made of condensed mana.

A crescent of mana shot out of the sword and cut through the mountain chunk, splitting it in half from the center. The two parts of the mountain fell away from where we stood, and behind it appeared the giant Behemoth.

It had deemed me a threat.

I hopped on the ground. Once, twice, again, feeling my blood pump once more—I set off.

The ground behind me shrank as I dashed through the mountains all around. With a leap, I jumped off the ground and took to the air. My mana formed a small platform beneath my feet, and once more, I pushed off it to run into the skies.

“GRWAAA!”

The Behemoth screamed and stretched its hand out—a giant, bellowing monster.

How fast could it be? Turns out, insanely fast. The Behemoth’s fist was in front of me in the blink of an eye. I kicked the air and changed my trajectory, going a little higher only to land on the Behemoth’s fist.

I ran.

I tore through the wind as I ran up the hand of the Behemoth. It screamed, growled, and tried to shake me off, but that wouldn’t pass.

The Behemoth raised its other hand and brought it down on me as if swatting a fly. I barely reached the size of its fingers.

I raised my blade and swung it up again. The sword of mana chopped off one of the Behemoth’s fingers as I jumped again and took to climbing the other hand.

How long had it been? Was it since the Final Assault? I hadn’t had a chance to face an enemy like this in a long time.

I reached the Behemoth's shoulder; there was nothing it could do anymore. The Behemoth tried to pull away as I lept off its body and up high again; I was in front of its face.

“There we…” I pulled my hand back… “GO!”

And punched it.

The air around us trembled as the Behemoth’s face warped around the punch. First, its head, then its neck, then its entire body was knocked off its feet as the Behemoth flew to the side.

Despite falling, the Behemoth did not give up. It swung its hand again, and this time, dozens of magic circles formed behind me.

I formed a footing in the air and turned back, only to see the magic circle dissipating.

It was a distraction!

As soon I turned around again, the Behemoth was back on its feet and right before me. Its fist, too, came swinging from the side.

I tried to block it, but was already too late. The fist of the Behemoth smashed straight into my entire body.

As I flew off this time, a burst of wind boomed through the skies. The Behemoth wasn’t done. It swung its arms again as dozens of magic circles formed around us.

The stones and rocks over the terrain trembled and shook, and they charged straight at me all at once. With each second, a new rock flew and smashed straight into my body. It had marked me with its magic and used me as a core to attract all these stones.

All I could do was fly away and slowly alter my direction.

The force finally dissipated, and I flew down like a rocket running out of fuel. My body, alongside the small ‘planet’ of stones I had formed, all crashed into the top of a clear mountain.

A giant crater formed where I fell, revealing the dozens of magic stones inside the mountain. I had dropped right next to Shirley.

I groaned and winced as the stones fell off, the magic’s effect ending. I slowly pushed myself off the ground and stood up. Blood flowed down my head and some parts of my skin.

“AAAH!” Shirley screamed as she saw me stand up. “H-how are you… alive—”

“Ouch, ouch, ouch,” I winced again and dusted my clothes, standing in the middle of the crater. “That hurt… motherfucker, I think he broke my ribs…”

“Ribs… j-just your ribs—”

“Shirley,” I cut her off. “I am sorry, but please just wait here a little longer. We have to get out fast.”

I wanted to save some strength, but it didn’t look like the time for that. Did it?

“Argh… I’ve lost my edge in this last year…”

I rolled my shoulders and cracked my neck. Peace really made people weak, huh? With a single last stretch, I shot off the ground again.

This time, I jumped straight to the Behemoth. I wasn’t planning to save my mana anymore.

The Behemoth’s eyes widened in surprise as I appeared right before it. Once again, I pulled my free hand back in a punch, and the Behemoth immediately crossed its arms in front of its face.

Rookie mistake.

I swung the sword in my other hand. Mana, incomparable to before, sleuthed out of my sword and dug into the Behemoth’s body. The sword's swing sent the air rippling as it dug into the Behemoth’s wrists…

And cut it apart.

“GWAAAH!” The Behemoth screamed, but I wasn’t done.

I made my way down again and kicked it in the stomach. The Behemoth’s body arched back as I jumped up again and drove my fist into its jaw.

The Behemoth was lifted off its feet again.

“Sorry, I have no more time to waste.”

Before the Behemoth could react, I raised my sword. All but a bit of the mana in my body started gathering at the tip of the blade.

The mana platform holding me up disappeared. One last kick, I jumped again straight to the Behemoth’s chest.

Dozens and dozens of magic circles formed in the air, but just like one couldn’t use magic inside a Mana Vein.

With the immense mana I used to cut them down, even Behemoths’ magic circles fell apart. My attacks were a moving, harnessed mana vein on their own.

I drove the sword through them all, cutting through circle after circle as the blade reached the Behemoth’s chest, right atop the magic stone that served as its core.

And there, the energy at the sword’s tip exploded.

—BOOOOOM!

A great wave of mana burst through as the Behemoth fell limp on the ground. Without missing a beat, I grabbed the magic stone, making its heart, and bagged. A level 10 stone was a gold mine.

I fell from the sky and to the ground again, but this height could barely hurt me.

As I fell, I dashed off once more to fetch Shirley. The girl was still where I had told her to stand, frozen in place with her jaw dropped.

“Thanks for waiting. That took a while,” I said, pulling my hair back. It had bloodied too much. “Let’s leave?”

“M-monster…”

I turned back.

“Where?”

There was no monster. Was she seeing things?

** Special Story: The Academy's Professor is Overly Weak?!**

If you transmigrate into a noble, don’t become the second son.

When I suddenly woke up in the body of the son of a well-off Earl in a grand empire, I thought I’d be able to live in peace.

I enjoyed grand meals, grand beds, and thought, eventually, grand friendships. I thought nothing would be in the way of this relaxed, rich life at the frontier. Money solved all, after all.

I was wrong.

“Ahem… we need to accumulate achievements in the war. The eldest is the heir, and the youngest is too young, so you go, son.”

My cold-hearted father uttered those words of love, handed me a bag of food, a letter of recommendation, and sent me to fucking war.

War against the demon king.

I trained hard at the war. It was tough, but eventually, they took me in and made me march to the Demonic Lands... when my foot slipped in a mountain. What could one expect from a modern citizen? I was not used to this.

My world turned upside down as I slipped down the mountain, and fell straight down where we came from.

There, I died.
