[Divine Dragon Mark: Snow]

She got a Dragon Mark of Snow, which seems similar to the one of ice. She also got Transformation, Ice Magic, Fighting Technique, Mana Mastery, Cute Appearance, Thievery, and Flexible Body as her new Abilities after evolving

What with these powerups? She even got magic out of it!

And Cute Appearance? Is this a charming skill like Benladann's?

[Cute Appearance]

The user has an irresistible and cute appearance, which can charm those weak to cute appearances, charming targets can be convinced more easily to do certain things for the user.

Huh I wonder if it could work for me if I eat her and get the Skill

Okay, better not imagine me acting cute.

Nor eating her, that's horrible!

I guess it is part of our mind to have such bizarre thoughts. It is something that we must ultimately embrace

Anyways, Draugann also got some boosts in her power, and she got the dragon mark of ice as well, quite generic compared to the other kids, but nothing that we can do over it! Right?

At the very least she got stronger, that's a good thing by itself.

Oh, there was also another change

"Oi, I think you forgot about me! I evolved as well, Drake!"

Fuyu surprised everyone as she spoke through the entire ice fortress, her voice had become more feminine, I suppose being my split mind doesn't mean it will act like me

Or does this means I have a feminine side?

We are better at never finding out the truth. Yes, let's leave it at that.

"Uwah! It's true, Fuyu, there's a new floor?! And space also seems wider now that I see it" said Benladann.

"Amazing, so your living fortress can evolve and rank up as a monster?! And by doing so it becomes even bigger?!" asked Draugann, almost falling over the ice floor.

"Haha, Drake is filled with insane cheats, you have to get used," said Yuki.

"Amazing, well done, Fuyu," I said.

"Fufu... I am amazing, aren't I~? This is the amazing home you all live in!" said Fuyu.

I quickly checked her stats and saw that she even got a Divine Dragon Mark, she had it over her Mana Core Battery Oh, I had also given her my blood, but she never got any skill out of it. Fuyu can't eat, to begin with, so I had tried spraying my blood over it and nothing happened.

Name: Fuyu.

Race: Great Flying Ice Fortress Golem (Female?)

Mana Core Cultivation: Rank 2 (Initial Stage).

Status: Gathering Mana, Prideful.

Average Estimated Vitality: 12.000/12.000

Average Estimated Mana: 8.000/8.000

Average Estimated Strength: 3.100

Average Estimated Dexterity: 800

[Material Assimilation]

[Mana Core Battery]

[Wind Magic Rune: Float]

[Icicle Spear]

[Fortress Defense]

[Protection Enhancement]

[Body Manipulation]

[Architecture]

[Divine Dragon Mark: Steel]

Fuyu's stats skyrocketed quite a lot. She had gone from Middle Stage to Initial stage of the next Rank after all Something that was incredibly odd, to begin with.

Maybe she was already close to getting to Rank 1 Peak Stage and ended ranking up twice? Well, whatever. The good thing is that she got stronger, and got some new Abilities as well to ensure our safety and the protection of everyone inside.

She got the Fortress Defense, Protection Enhancement, Body Manipulation, Architecture, and Divine Dragon Mark: Steel Abilities.

The first two skills enhance her defensive abilities, both magic and physical, while protection enhancement increases all her stats while there are people inside of her that she is protecting from an outside attacker.

Body Manipulation helps her manipulate the formation of her own body, she can slowly adjust herself around, even moving whole floors and interchanging their positions And Architecture gives her a greater insight while building her own body.

Lastly, her Dragon Mark seems to have the effect of making her body harder than steel, reinforcing her materials to even higher degrees It was a perfect Dragon Mark! Thanks a lot, Fafnir-sama!

"Our home got bigger now, so we can play more!" said Flayr.

"Y-Yeah!" said Noirenn.

FLASH!

CLASH!

Suddenly, a flashing spear opens the large gate and lands on the floor!

It was Skadi!

And it was she was covered in blood.

"Ahhh Nothing better than bathing myself in the blood of my enemies," she said.

Eh? She spoke!

She Don't tell me

Oh god Fafnir-sama never misses.

She had a Dragon Mark! Near her tip.

"Uwah! T-That's your spear, right?!" asked Benladann, feeling horrified.

"Why is it talking? Well, it could move by itself so I was already imagining it could do some crazy stuff," said Draugann.

"Drake gave it a piece of his soul and it became something similar to Fuyu. It gained a Dragon Mark despite being a weapon too" said Yuki.

"Hm I've been blessed by someone, and my power has skyrocketed, Master. Please, order me and I shall slaughter anyone," said Skadi.

"Okay, let's calm down for now How about you wash yourself?" I sighed.

"O-Oh Right," sighed the spear, as she floated away and went to the bathroom.

Well, that's that, we'll have to get used to a talking bloodthirsty ice spear from now on.

After the Dragon Marks, it seems that all the kids regained their strength ad was healed from the fever too, which was mana-related.

Additionally, all of them gained Mana Manipulation and became better at using magic, well, a little bit, but it is better than before, that's for sure.
