From what I've investigated, the monsters in this place are all related in the evolutionary sense.

Frost Goblins evolve into Frost Goblins with a "job" after increasing their Stage one or two times, and then, after that, they evolve into Ice Orcs. After an Ice Orc reaches Peak Stage they evolve into the powerful Old Yeti.

I guess it is gradual, they're all blue-skinned and are slowly growing white fur across their bodies, when the giant and burly Ice Orc evolves, their entire bodies grow up to four meters and their muscles become bigger, they are completely covered by white fur and resemble gorillas standing up. They usually wield a giant ice club they make with magic.

One of them spawned on floor 1, it seems that they randomly appear in the floor's last room as a Mid-Boss. The last Boss of the Dungeon is often a similar Old Yeti or their superior evolved version, the Old Yeti King who are Rank 2 Initial Stage.

And there had been cases when the dungeon accumulates too much miasma and becomes an Old Yeti Emperor, who are Rank 2 Middle Stage! Those can't be handled properly by newbie sect members, not at all

But this guy was a run-of-the-mill Old Yeti.

"GROOOAARR!"

He came with a swarm of Frost Goblins with Jobs, around 30 of them, and 10 Ice Orcs! What a nice loot! There's a lot of meat here too, we can feed more people. I already tasted them a bit, they are pretty fine, surprisingly for monsters so ugly, but I guess because they are generated by the dungeon through magic, they taste good.

"Let's do it, Noirenn!"

"O-Okay!"

Flayr and Noirenn sat over Frost as they began to bombard the initial wave of Frost Goblins with Jobs, the blazing explosions of the giant fireballs of Flayr and the piercing Shadow Spears of Noirenn put them down quite easily!

BOOM! BOOM! BOOM! BOOM!

Although some of them sneaked towards them it was nothing that our four-meter-big Frost, their guardian, couldn't take, as he used his paws to crush the goblins and his claws to slash them, his jaws even caught some of them alive and swallowed them I hope he can digest the mana core though.

"Hehe, easy meals!" laughed Yuki, as she used her sharp metallic claws and began to slash through two Orcs at once, she moved at such amazing speed it was mesmerizing to see.

SLASH! SLASH! SLASH! SLASH!

Her claws slashed through the two Orcs as their limbs easily fell into the ground, they roared angrily and fired spikes of ice at her, but they were useless as she kicked and slashed them.

The swarm of goblins was also intensively trying to bathe us with piercing icicle spears, but Flayr and Noirenn's attacks were too much for them, they ended getting crushed.

Benlah and Laddan, Benladann's parents, joined the fight as well.

Benlah moved gracefully as she used her Ice Bow to fire several explosive ice arrows, freezing several goblins on the spot, although they could free themselves from a frozen status, Laddan came forward with his monstrous strength and his new dragon gauntlets which I made for him, he used his sheer strength to crush them into pieces before they could free themselves.

CRAAASH! BOOOM!

Pekora and Tisha and their armies also joined the massacre, as they ganged over the Orcs, throwing them into the ground and slaughtering them one by one.

"GGRRUUAARRR!"

The Old Yeti released a roar that made everyone tremble in fear instinctively, he had the Intimidating Roar Ability after all, and was at Rank 1 Peak Stage, aside from Yuki and Frost, the rest were not Rank 2 yet.

I decided to not intervene with Benladann, as we thought that it would be better for their training to fight this monster by themselves. Frost and Yuki were also told to give more space for the others to fight for now.

Laddan was the one that greeted the Yeti, his enormous size, and strength while infusing his body with the power of the Dragon Mark of War made him strong enough to withstand the powerful punches of the Old Yeti, as he gritted his teeth and bathed the Old Yeti with his own fist attacks, which even left some burnt marks on the monster's white fur due to the friction, but he seemed mostly fine even after that!

"Honey!"

Benlah fired several arrows to assist her husband, piercing the Yeti's skin with them and making several wounds across its big body. The Old Yeti was slow and could not catch up to her, even less with Laddan bothering him so much.

Flayr and Noirenn, alongside all the long-ranged magic attacks from the Ice Elves and the Rabbit-kin groups, coordinate themselves and began to bathe the Old Yeti with all sorts of attacks.

Flayr and Noirenn's fireballs and shadow spears were quite strong, but there were also rays of sunlight from Pekora's Sunflower, and the rolling boulder spirit, alongside other spirits.

The Ice Elves were proficient archers like Benladann's mother and bathed the Old Yeti with their own attack as well. The creature groaned in agony as it began to falter and fall back, Laddan used this opportunity to crush its chest with a powerful Palm Strike Unarmed Fighting Technique!

CLAAAASH!

"Grruuuaaggh!"

The Old Yeti fell over the ground as it conjured a storm of ice, sending Laddan through the airs!

"Uagh!"

BOOM!

The ice giant fell over a pile of snow as the Old Yeti stood up again, only to be greeted by several slashing attacks from Yuki right on his face!

SLASH! SLASH! SLASH! SLASH!

"GGRUUAAAGH!"

The old Yeti tried to throw Yuki away, but she sneaked outside of his range, leaving the kill for the rest!

A bombardment of long-ranged attacks continued over the giant, its body couldn't last any longer and began to flow with rivers of blood everywhere, the creature gave a loud and last roar, and fell to the ground, to never stand up again.

BOOM!

"We did it!"

"It's really dead!"

"Oof"

"That one was tough."

The party members all began to celebrate, it was a tough creature to kill and it took their combined effort A few items emerged at the side of the corpse, some shone brighter than others.
