The Extra's Advent: My Villainess Fiancée is a Yandere-Chapter 26: Creating SS-Rank Skill [1]

Faceless Mask Construct

Rank: A

Type: Disguise

Description: The skill alters the user’s face, voice, skin, and mana signature. The disguise remains active indefinitely and will not deactivate unless the user willingly dismisses it. While highly effective against standard perception methods, it cannot bypass high-tier detection abilities. Mana consumption is low but continuous while active.

...

’It’s a good skill.

’As long as I avoid high-tier detection abilities, I can do as I please.’

’Heh... what are the chances of running into someone at [Mythril] and above?’

’Not to mention, even among high rankers, detection skills are rare.’

’Even in the worst-case scenario where I’m detected while using this skill, at most, they’ll know I’m disguising myself. They won’t see through the construct itself.’

Cael cleaned his sword in the river water, his thoughts calm and calculated.

Then he turned and glanced at the corpse nearby.

It belonged to the creature that had disguised itself as the injured girl.

Its skin was dark green. Two curved horns protruded from its head, and its face resembled that of a goblin.

"Skinwalker...?"

Cael was slightly startled.

He knew this dungeon housed creatures capable of disguise, but he hadn’t expected Skinwalkers.

Even though Skinwalkers could not evolve beyond [Diamond] rank, their threat classification was placed in the SS-category.

However, they had two major weaknesses.

First, they could not survive in the surface world for long, as they required a dense concentration of pure mana to sustain themselves.

Second, they were extremely vulnerable to sunlight, preferring to dwell in darkness.

Cael exhaled softly and shifted his gaze forward.

The same pack of gnolls he had retreated from earlier was charging toward him again.

"You guys are quite persistent."

He tilted his head slightly.

"Fine. Since I’m in a good mood, I’ll play with you."

Frostflame surged from his palm as he created an ice bridge across the river and stepped onto it.

Seeing their target retreat once more, the gnolls rushed onto the frozen surface without hesitation.

The corners of Cael’s lips curved upward.

He lifted his hand.

—FLAAA—

Frostflame erupted from beneath the bridge, surging upward and engulfing the entire pack.

Their distorted screams echoed briefly before being silenced.

In minutes, the gnolls stood frozen mid-motion, transformed into jagged ice statues.

Cael watched them with indifferent eyes.

"Idiots."

Cael checked his progress and smiled. 𝒇𝒓𝙚𝒆𝔀𝓮𝓫𝒏𝓸𝙫𝓮𝓵.𝓬𝙤𝙢

After learning that skills could be fused into elements, he stopped holding back.

Whenever he saw someone use an elemental skill, he copied it and merged it with his own elements. That was the reason his elemental masteries had risen so quickly.

Not only that, but he had also gained the Water element thanks to Aria Jasmine.

He had copied Lightning skills from Kira and Shadow skills from Edwin as well, but interestingly, he no longer gained new Lightning or Shadow elements.

From this, Cael concluded that once an element was merged into a special element, he could no longer obtain it as a separate base element, even if he copied related skills afterward.

To test this theory, he copied Fire and Ice-related skills.

Sure enough, his theory proved correct. He only obtained Fire and Ice-type skills, without gaining the elements themselves.

He then merged those Fire and Ice skills into Frostflame.

Similarly, Shadow and Lightning skills were fused into Black Lightning.

Now, his first special element, Moonlight, was being left behind by the others.

Cael sat atop a large tree branch, staring into the darkening forest.

Tomorrow, he would challenge the dungeon boss.

According to gathered information, the boss was a Minotaur.

And it possessed an S-rank skill called Energy Construction.

It was an excellent skill, and Cael wanted it.

It wasn’t as though he hadn’t encountered other skills at the academy.

In fact, He had.

He simply found most of them useless.

So, he rejected them.

...

On the Surface, District Kazi

District Kazi had a radius of roughly twenty miles.

Although it was called a district, it was nothing more than a stretch of slums.

Crumbling buildings leaned against one another as if exhausted from standing. Narrow alleys twisted between piles of scrap metal and broken stone.

Dim lanterns flickered weakly in corners where shadows gathered thicker than the light.

It was a place where the homeless survived, where thieves prospered, and where law enforcement rarely stayed longer than necessary.

It was no surprise that kidnappings had flourished here for over a century.

Cael’s wind clone, along with Kira, Edwin, Aria, Luke, and Mira, finally arrived at the outskirts of District Kazi.

However, neither Team Gray nor Team Sparrow entered the district immediately.

Instead, they booked rooms at a modest hostel in a neighboring city to avoid drawing unnecessary attention.

Cael, Luke, and Edwin shared one room.

Mira, Kira, and Aria took another.

Later that night, Luke stepped onto the balcony and looked up at the dark sky.

The pale and distant moon hung quietly above the city.

"Cael," Luke called, his voice calm.

"Come here. I have something to discuss."

Cael frowned slightly but stepped onto the balcony nonetheless.

"What is it?"

Luke studied him for a brief moment before speaking.

"It’s only a suspicion... but..."

"I think... Kira Crimson is a Vampire."
