The Fukaros Familia, starting from DanMachi.

Further away, an even more imposing Rock Shield Hilichurls, wielding enormous rock shields, were slowly approaching with heavy steps.

In the sky, several rush-class Honkai Beasts, resembling mosquitoes with white shells and pink markings, were flapping their transparent wings and making a buzzing sound, searching for an opportunity to launch a surprise attack.

This is a monster group with a clear division of labor, consisting of far-range, mid-range, and near-range units, as well as ground and air units.

"Robin, watch out for those rockets!"

With a low shout, Fen Yu began to move.

Instead of taking the hit head-on, he used his agile footwork to weave through the stalagmites and easily dodge the first volley of rockets.

He stopped using magic when faced with the charging Hilichurls.

The longsword was drawn, bringing with it a flash of silver light.

Instead of retreating, Fenyu advanced, charging towards a charging Hilichurl.

Just before they were about to collide, his body twisted at an incredible angle, and his longsword drew a tricky arc from bottom to top, precisely slicing through the Hilichurl's wrist holding the staff.

The charging Hilichurl let out a scream as its burning staff flew out of its hand.

Without pausing, Fen Yu lunged forward, his elbow slamming into the opponent's chest. The immense force caused the opponent to falter, and then his longsword swept across, sending a masked head soaring into the sky.

After taking down one, he didn't even look back. With a backhand slash, he parried the attack of another charging Hilichurl, using the momentum to leap backward, while simultaneously uttering that destructive syllable once more.

"Gospel!"

An invisible sonic wave struck a rocket Hilichurl on a distant stone platform with pinpoint accuracy. The Hilichurl didn't even have time to scream before it was blown to pieces along with its crossbow.

However, the moment he used his magic, a long-lurking, rush-class Honkai Beast seized the opportunity.

It emerged from Fenyu's blind spot, transforming into a white lightning bolt, and lunged forward with astonishing speed, its sharp mandibles aimed directly at his back.

A sharp whooshing sound came from behind his blind spot. The rushing-class Honkai Beast seized the moment when Burning Feather was chanting magic, transforming into a deadly white lightning bolt, its sharp mandibles aimed straight at his heart.

However, Fen Yu showed no panic in the face of this sudden attack.

Having been "beaten up" by Alphia in all sorts of bizarre ways over the years, he had long since developed a combat instinct and a keen sense of danger that surpassed that of ordinary people.

More importantly, he was not fighting alone.

He has partners he can absolutely trust.

Sure enough, just as the Honkai Beast was about to succeed...

"Play it!"

A clear and elegant chant rang out, and a sound wave, arriving later but arriving first, struck the flank of the charge-class Honkai Beast with perfect accuracy.

"Buzz—!"

Under the impact of the high-frequency sound waves, spiderweb-like cracks instantly covered the Honkai Beast's hard shell. Its high-speed charge suddenly stopped, and its entire body lost its balance in mid-air, tumbling and crashing to the ground.

Burning Feather turned around and met the robin's lake-green eyes.

The two exchanged a knowing smile, everything understood without a word.

The pace of the battle did not stop as a result.

With a backhand strike, Fen Yu finished off the Honkai Beast that was still struggling on the ground, then locked his gaze on the several giant slimes.

The large fire slime was accumulating heat, its body resembling a miniature volcano about to erupt; the large ice slime was condensing sharp ice spikes on the surrounding ground; and the large rock slime, like a moving fortress, was slowly pressing in.

"Gospel."

Burning Feather once again used Alphia's magic, and the invisible sonic bombardment accurately struck the large fire slime.

However, this time the effect was not as good as before.

The large slime's gel body was thicker, and although the sound waves made it retreat repeatedly, they failed to kill it instantly.

At the same time, the robin also moved.

She raised her hand, her slender fingers tracing graceful arcs in the air.

"Play it!"

Sharp sonic waves shot out from her fingertips, not aimed at the thick-skinned rock slimes, but precisely at the rocket Hilichurls who were still firing arrows from afar.

The sound waves penetrated their rudimentary armor, exploding inside them and eliminating these ranged units one by one.

Burning Feather immediately understood the robin's intention.

Instead of wasting mana bombarding the large slimes, he turned his attention to the Rock Shield Hilichurls who were steadily advancing, wielding giant shields.

He took a deep breath, lowered his body slightly, and returned the longsword to his waist.

"Gospel!"

This time, the sound waves were no longer fired in a straight line, but instead formed an invisible shockwave in front of him, which spread forward rapidly.

The two Rock Shield Hilichurls at the forefront were thrown to the ground by the immense force, revealing their vulnerability.

Fenyu's figure vanished from the spot in an instant, like an arrow released from a bow, passing by the overturned Hilichurl.

His longsword flashed a silver arc as he charged, precisely slicing through the gap between a Rock Shield Hilichurl's shield and body, taking away the arm holding the shield.

Without the protection of their shields, the burly Hilichurls are like lambs to the slaughter.

Without even turning around, Fenyu pierced its heart with a backhand sword.

At that very moment, another Honkai Beast of the Rush Class swooped down from the sky.

This time, the robin's magic struck precisely in its path, forcing it to change the trajectory of its attack.

This brief pause was enough for Fenyu.

He lightly touched the ground with his toes, leaped high into the air, and performed an incredible spin in mid-air. His longsword slashed down from above, cleaving the Honkai Beast and its wings in two.

The moment it landed, a scorching wave of air hit it from the side.

It was that giant fire slime; it had finally finished charging up and spewed out a huge fireball.

Fen Yu neither dodged nor avoided, and chanted again.

"Peace of the Soul".

A layer of almost transparent sound waves wrapped around his body, transforming into an invisible armor. The moment the powerful fireball touched the invisible armor, it vanished silently, like a punctured balloon.

The Garden of Tranquility, an additional magic of Alphia.

The instant the fireball was nullified, Fen Yu's body charged forward again, his longsword piercing straight into the constantly pulsating magic stone core inside the large fire slime.

Amidst the clamor of battle, Robin's hood was accidentally blown off by a shockwave, and her long, flowing, silver-purple hair cascaded down like a waterfall, reflecting a dreamlike luster in the dim light of the dungeon.

Her stunningly beautiful face, capable of making even the gods pale in comparison, was thus exposed to the air without any concealment.

With the last large ice slime being shattered by the combined efforts of Burning Feather and Robin, this brief but intense battle finally came to an end.

These scenes, which can be described as works of art, were all seen by two people in the shadow of the stalagmite not far away.
