Science/Magic

Sebastian was standing in the air above the monsters.

Thousands and thousands of monsters marched towards the walls of the city. The roared and screeched with bloodthirsty eyes, eager to taste the blood of the humans behind the walls.

Sometimes, bird-like monsters attacked Sebastian. Every time that happened, Sebastian would swing his sword, bisecting the monsters before they could approach one hundred meters near him.

However, Sebastian knew how useless this was.

Even if he killed one hundred, one thousand, or ten thousand monsters like these, it would be useless. Fifty thousand monsters and forty thousand monsters were equally dangerous for the people of the city. But he would have drained his strength.

No, his task here was to kill the strongest monsters. A-Rank monsters. Once he killed the monsters that could threaten the city walls, he could spend his remaining strength in the small fries.

Fortunately, he did not need too much time to find the first one.

Three kilometers away, he saw a tiger-like monster standing over a rock. The tiger roared angrily to the sky, displaying its fury and desire for blood.

Just a glance was enough for Sebastian to detect its strength.

A-Rank.

Sebastian's eyes narrowed. He shook off the blood on his sword and kicked the air.

Then, he appeared just above the tiger.

"Die." With an ice-cold tone, his sword slashed down.

*Booom!!!*

The sword slash crashed against the ground. Powerful mana waves exploded in the surroundings, killing all the monsters nearby. Just that sword slash was enough to create a one-hundred-meters-long crevice on the ground!

But–

"How unexpected. To think The King's Right Hand himself would appear so far away from the capital."

–A voice spoke from the ground.

A black-dressed man appeared in Sebastian's sight. He was holding a narrow long sword while defending the tiger-like monster from the attack.

Then, something even more unexpected happened.

The tiger kneeled down on the ground and growled submissively to the black-dressed man. When the man nodded, the tiger stood up and ran away.

Sebastian was surprised. The scene of an A-Rank monster bowing to a human was enough to give him too many things to think about.

"Who are you?" Sebastian asked.

"You don't need to know." The black-dressed man chuckled. "You only need to know that the reason I'm here is to stop you from interfering with our master's plan."

"… Master?" Sebastian was surprised. "Are you telling me that this disaster was caused by someone?"

"What do you think?" The black-dressed man tilted his head. "Okay, you don't need to know too much. Are you going to fight or not?"

"Hmph!" Sebastian snorted. Strong sword intent surged out of his body, charging towards the black-dressed man.

But the black-dressed man laughed. With a wave of his sword, sword winds were created, dissipating the sword intent completely.

The next second, both swords collided in an earth-shattering clash.

Just like that, the fight between two demigods started.

Meanwhile, the monsters arrived at the walls of the city.

And unfortunately, there was not a demigod to stop the strongest monsters from attacking.

…

The first monsters that attacked the city were the flying monsters.

Pigeons, eagles, vultures, nightingales, hawks, bees, flies, and many other kinds of birds and insects charged towards the humans on the walls.

The human's replied with their own attacks. Arrows and spells flew from the city walls, crashing towards the cloud of monsters coming to the city.

***Screeeeeechhh!!!***

The screams of pain and rage from the flying monsters assaulted the defenders' ears. Corpses fell from the sky, crushing the monsters below and causing confusion on the beast wave.

But many more monsters managed to survive the rain of arrows.

***Screeeeeechhh!!!***

With the bloodthirsty cries of the eagles and hawks, the first birds managed to reach the walls. Then, their claws turned into a grinding machine that reaped flesh and blood, killing tens of defenders in the first five seconds.

Moreover, many flying monsters did not even bother with the defenders. They flew over the city walls, going to the undefended parts of the city to feast in the flesh and blood of the civilians.

"Kill the monsters!" A mage shouted valiantly. Tens of fire arrows were shot towards the monsters, burning them into cinders.

But at the same time, more powerful monsters were attracted to the man. The hawks cried in rage and dived towards the mage with their claws ready.

The mage did not panic. Mana shields were created in front of him while fire whips entangled and burned the monsters. Just this was enough to show how experienced this mage was in combat.

Unfortunately, not even a B-Rank mage was guaranteed to survive in this hell.

Suddenly, a very strong eagle charged towards him. The peak B-Rank eagle pierced the shields as though they were paper, and its beak crushed the mage's head.

Then, it flew to another part of the battle.

It killed and killed, using its wings like sabers and its claws like swords.

City guards and adventurers fought against it, using their swords, spears, and arrows to try to kill it.

But even when the eagle was covered in injuries, it continued killing. It ignored the spear piercing its belly, and the sword that severed its wing. The arrows on its neck and chest only served to make it more infuriated.

Even when it seemed as though the eagle was about to bleed to death, it continued fighting. Its bloodthirsty eyes shone maliciously while its beak crushed everything in its path.

Just this eagle alone was enough to create a giant hole in the city defenses.

"Stop it!"

"Don't let it escape!"

"Someone, help my brother!"

Amidst the terrified cries of the crowd, the eagle finally set its sight in one of the city guards.

It was a young city guard, frozen in fear in front of the beast's pressure. Even when the beast was about to crush him, he could not move.

*Screeeech!*

The eagle screeched madly. It extended its claw and swung it to the poor city guard.

But–

*Boom!*

A punch hit its head.

Blood-red man bloomed above it, surrounding a beautiful and slender girl with an indifferent face.

"Hey."

The beautiful girl clenched her fist and her gloves lit up with beautiful crimson light.

"Get lost!"

With a punch of the demon, the already injured eagle was crushed against the ground.

With the next punch, its heart stopped beating.
