I Was Reincarnated with OP Invincibility, so I’ll Beat ’em Up My Way as an Action-Adventurer

113. In The Name Of The Six Demon Generals

“Now, shall we kill each other to our hearts’ content? I will kill you and fulfill the Demon King’s command.”

The air around Meriel shimmered like a heat mirage.

“In the name of the Six Demon Generals—yes, I am the trusted right hand of the honorable Demon King…”

From the void, countless black objects began to seep forth.

It was a staff, black as pitch.

One, two, three—their numbers grew rapidly.

Soon enough, the sky was filled with thousands of staves, befitting the title ‘Master of a Thousand Spells’.

“Demonic magic is different from human magic, you know. Not just in power, but also in speed—it requires no incantation delays.”

Meriel announced from above, flapping her black wings with a rustling sound.

“The magic I specialize in is high-speed, continuous attacks. In human terms, each blast has the power of an ultra-class rare spell.”

There was a time when Lilith used Magic Missile to amplify her power and defeat a Class A dragon.

That spell was of the ultra-class rare spell level.

“Let’s see if your defenses can withstand it all, shall we?”

Meriel raised her elegant right hand.

“[La Gu Dire].”

One of the thousand staves unleashed a lightning strike bathed in golden light.

“[Ria Vi Zes].”

Another staff emitted a blue glow, sending forth a torrent like a tsunami.

“[Ga Ber Ku Dire].”

A third staff glimmered black and launched an orb of shadowy energy.

The thousand staves floating in the void began glowing one by one, bombarding the battlefield with spells in rapid succession.

It was truly a relentless high-speed magical assault.

Colors filled my vision—lightning, water streams, flames, energy blasts, and shockwaves hurtling towards me, exploding all around.

As Meriel had promised, she unleashed dozens—perhaps hundreds—of ultra-class rare spells in rapid fire.

Compared to human magicians, she was on a whole other level. This is what it means to face one of the Six Demon Generals.

The earth-shaking roars, the blaze of explosions, and the tremors didn’t stop. It was enough destructive force to wipe out a city or two.

But thanks to my defensive skill, I took no damage. The rainbow-colored dome encircling me didn’t waver in the slightest.

“Not even Gyrasvrim’s sword or Dialva’s curses could penetrate that defense…It seems my magic cannot breach it either.”

Meriel muttered to herself.

“But I know… Your defensive skill has a time limit. Eventually, it will expire.”

The young demon general smiled faintly.

“And it takes a brief moment to activate the next skill, right? That moment of focus—before you can defend again—will be fatal in the face of my continuous magic.”

My improved skill could now last for about fifteen minutes.

But as Meriel said, once it expired, my enemy’s magic would burn me before I could reactivate it.

“[Ash G U Mer]!”

Four violent tornadoes surrounded me from all sides.

“What is this…!?”

Even though the tornadoes were deflected by my defense, they didn’t dissipate. They continued swirling around me, slamming me with shockwaves.

—She’s planning to use continuous attacks to strike when my skill wears off.

“So, when will it run out? There’s no escape, Haruto.”

The shockwaves whirled violently, tearing at the floor and even the very air.

“I’m not planning to run.”

“Trying to sound tough… Your defense must be wearing thin by now, right?”

“No.”

I shook my head quietly.

“It’s already gone.”

“Wha…!?”

This time, it was Meriel’s turn to be shocked.

“Don’t tell me… you’ve layered your barriers!?”

Yes, this was a technique I mastered during my fight with Greed.

I had learned to activate up to seven skills simultaneously, instead of just one at a time.

The principle was simple.

First, I activate the defensive barrier [Armor Phase].

Then, a few minutes later, I stack a second [Armor Phase] on top of it.

Even when the first skill expires, the second one is still active.

This eliminates the weakness of having a gap between the skill’s expiration and reactivation.

As long as I stay conscious, the [Armor Phase] will continue to protect me indefinitely.

“Such defense…”

Meriel’s expression grew strained.

She bit her lip and groaned.

“This wasn’t in the information we gathered.”

“I’ve grown stronger. I had good teachers.”

“Humans… grow at a frightening pace. I see.”

Meriel muttered in awe.

“That’s a power we, who were born strong, can hardly understand… or possess.”

“What will you do? I’m not just capable of defense. I can reflect your attacks and strike back. But—”

I still hesitated.

Meriel was different from the other demons I had faced.

If she had come as an enemy from the start, I wouldn’t have hesitated to attack.

But I’d seen her interact with Lilith and Alice.

I had even gone on quests with her myself.

It wasn’t easy to bring myself to attack someone like that.

Even if she was a demon.

Human emotions don’t work that simply.

“—But you kidnapped Lilith and Alice. I have to defeat you.”

I clenched my teeth in frustration.

There was no time to hesitate.

I had to do it—

“Please, stop this, Meriel-san!”

“Don’t fight Haruto!”

Suddenly, familiar voices rang out.

I whirled around in surprise—and there they were.

Lilith and Alice stood before me.
