However, once they passed the third floor, they no longer had the leisure to make such idle chat. As they descended into the fourth floor, they were forced to fight for their lives.

「OOOOOOOOOGH.」

「DIIIIIIIIIE!」

「Why are there Rank 3 Zombie Soldiers and Wraiths coming out all of a sudden?!」

「Cashew! There’s a Skeleton Archer aiming at us from further inside!」

「Hyiih! There’s even a Stone Golem coming this way!」

Up until the third floor, Vandalieu had cleared the monsters once, so there were few Rank 2 monsters. However, he had not defeated a single monster on the fourth floor.

In addition, the Stone Golems that Vandalieu had created to avoid traps had been added to the Dungeon’s repertoire of monsters.

And since Cashew and his companions did not possess the【Death Attribute Charm】skill, the Undead attacked them fiercely.

Cashew’s party, the『Wind Chasers』, were aiming for a promotion to C-class, so they had fought not only Rank 3 monsters but even Rank 4 monsters in the past, and they had even combined all of their members’ strength to defeat a Rank 5 monster on one occasion. They were veterans that would be able to defeat Rank 3 monsters, even if they were outnumbered two to one.

However, they were not strong enough to be able to continuously fight against an endless swarm of them.

「Shit! We’re retreating for now!」

Deciding to make a tactical retreat before sustaining too many losses, Cashew and his party returned to Terow and gave up on conquering the Dungeon on their own, joining forces with the『Steel Wings』and the『White Stars』before challenging the Dungeon once more.

With fifteen D-class adventurers gathered together, they were to get through the fourth floor without difficulty and barely managed to conquer the fifth floor. However, they fought an incredibly difficult battle against the Rank 6 Black Skull General and the ten Rank 4 Cursed Armors.

In the end, they were forced to retreat as well and the Adventurers’ Guild commissioned a C-class party for the first clearing of the Dungeon. However, those C-class adventurers were disappointed.

「I had high hopes since this was an uncleared Dungeon, but this is all we get, huh.」

They defeated the Black Skull General safely, but there was no treasure desirable for C-class adventurers in the treasure storage room; the items there were only worth loose change in their eyes.

The weapon and shield used by the Black Skull General was using a problematic Mana absorption ability during the battle, but they fell to pieces as soon as he was defeated, so the adventurers were unable to claim them for themselves.
