The Fukaros Familia, starting from DanMachi.

After bidding farewell to Eina, who had given them countless instructions, Burning Feather and Robin finally arrived at the very center of Orario, at the magnificent white tower—the Tower of Babel.

This is the entrance to the underground city.

The huge plaza at the base of the tower was bustling with people, adventurers either gathering in groups or checking their equipment, the atmosphere tense yet orderly.

At the entrance, several guild staff members were responsible for verification.

The process is very simple; all you need to do is show your adventurer ID card.

As the crowd surged forward, the two stepped inside the Tower of Babel.

A wide spiral staircase, large enough to hold thousands of people, leads down into the deep underground.

This is the "Path of Beginning," the 0th floor of the dungeon, an absolutely safe zone where monsters never spawn.

The air became cool and humid, and the light gradually dimmed.

The moment they climbed the long staircase and stepped onto the first level of land, a whole new world unfolded before their eyes.

This is the first underground level, a shallow cave.

The uneven rock floor and the glowing moss growing on the walls are the only sources of light, illuminating the entire space in a dim light.

At that very moment, Fen Yu felt a sudden heat on his back.

He knew that the "Gaze of the Abyss" had been triggered.

"Robin, watch out!"

Fen Yu whispered a reminder, his right hand already gripping the hilt, and slowly drew the longsword.

The robin immediately understood, raising its staff, the magic stone at the tip glowing faintly, ready to unleash magic at any moment.

As they continued onward, the surrounding adventurer teams gradually dispersed, and soon, they could no longer see any other people in their field of vision.

Suddenly, the rock wall on the side shattered with a "crash," and a short, dark green goblin screamed as it rushed out, brandishing a rusty dagger.

Facing such basic grunts, Fen Yu showed no emotional fluctuation whatsoever.

He stepped forward, his longsword drawing a clean, sharp silver arc as it precisely sliced ​​open the goblin's neck.

Black blood splattered, and the goblin let out a short scream before collapsing to the ground with a thud. Then, with a "thud," it turned into a cloud of black ash, leaving behind a magic stone the size of a fingernail.

The robin stepped forward, picked up the magic stone, examined it curiously for a few moments, and then put it into the backpack behind him.

Since there are no hired support staff, she is temporarily taking on the task of collecting the loot.

Next, they killed several more goblins.

Just when everything seemed to be going smoothly, the expected change finally occurred.

The ground in front of them suddenly shook and cracked, and a monster that should never have been there emerged from the ground.

It was a spherical gel-like creature, about the size of a human head and entirely fiery red.

"Fire Slime..."

Fen Yu's pupils contracted slightly as he instantly recognized the monster from his distant memories.

His eyes narrowed, and his figure moved like lightning. His longsword left a trail of afterimages in the air, instantly slicing through the slime's body and bringing with it a trail of red, viscous liquid.

However, the next moment, the eyes of both Fenyu and Zhigun froze.

The slash, powerful enough to cut a goblin in two, only left a deep gash on the fire slime.

The gash was visibly moving and healing, returning to its original state in less than two seconds.

Immediately afterwards, the fire slime's body shrank abruptly, then it shot up like a cannonball, crashing towards Burning Feather with a scorching shockwave.

With a quick sidestep, Fen Yu narrowly avoided the impact, then swung his sword backhand, sending the fire slime flying.

"Fenyu, your sword!"

The robin's clear, cold voice suddenly rang out.

Fen Yu looked down and realized that the part of the steel longsword in his hand that had been struck was red-hot, as if it had been scorched in a furnace.

He glanced at the fire slime, which had returned to normal, and frowned.

Physical attacks are ineffective, and the high temperature inside the body will cause significant wear and tear on weapons.

Although the attack method is simple, it is already very unfriendly to novice adventurers who are poorly equipped.

Just as he was pondering, the fire slime suddenly stopped, its body wriggled, and it opened a non-existent "mouth" towards Fen Yu, spitting out a fireball the size of a fist.

"Play it!"

Robins react with lightning speed.

She pointed her staff directly at the fire slime and uttered a short incantation.

An invisible, ear-piercing sound wave shot out and struck the fireball, which was still in mid-air, with pinpoint accuracy.

"boom!"

The fireball detonated prematurely in mid-air, exploding into a dazzling display of fireworks.

Fen Yu's lips twitched involuntarily.

There are even magical attacks? This isn't just unfriendly to newbies; it's downright a "newbie killer."

Which normal novice adventurer could deal with a monster that can attack with ranged magic on their first dungeon run?

However, since it is a monster born from the dungeon, it must follow the laws of the dungeon—its weakness must be magic stones.

No matter how strong one's regenerative abilities are, once the magic stone within one's body is shattered, death is inevitable. Having understood this, Fen Yu no longer hesitated.

He suddenly exerted force with his feet, and his whole body shot out like an arrow released from a bow.

The longsword in his hand no longer aimed for a fatal blow, but instead transformed into a flurry of sword light, continuously slashing at the fire slime.

Several sword lights flashed, and the fire slime's gelatinous body finally couldn't withstand it and was completely split into several pieces.

A magic stone emitting a red glow was also exposed to the air.

This time, the slime fragments that fell to the ground did not heal.

"It seems that if the damage caused in an instant is large enough, it won't have time to regenerate."

After making a decision, Fen Yu abandoned the idea of ​​directly attacking the magic stone.

After all, destroying the magic stone means no income, so it's a last resort.

He stepped forward and picked up the trophy, which was clearly a size larger than the goblin magic stone, as well as a clump of still-warm, fiery red slime that had fallen to the ground.

"Is this the 'unique monster' that appeared because of your skill?"

The robin stepped forward, a hint of solemnity on her beautiful face.

"It's much harder to deal with than a goblin."

She had also seen the information provided by Eina; the first level of the dungeon did not contain any monsters like fire slimes.

Needless to say, a monster capable of casting magic should at least be a mid-level hellhound.

Although the fire slime's attack power is far less than that of the hellhound, its troublesome nature is enough to give newcomers a headache.

Just then, a series of exclamations and screams, mixed with the sound of fireballs exploding, faintly came from other passages not far away.

Burning Feather and Robin exchanged a glance, both seeing the same thought and a wry smile in each other's eyes.

Clearly, the "surprise" brought by the "gazing abyss" was not just for him alone.

The entire first level of the dungeon was forced to begin this novice trial that should never have happened.
