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

175. Only To Vanish

“It seems like we’ve taken care of all the demons around here.”

I glanced around the area.

“Shall we head to the next spot──”

Just as I said that, I noticed Lilith and the others breathing heavily.

Everyone seemed pretty exhausted from the battle with the Demon Generals.

“Let’s take a break. It’s too dangerous to keep going like this.”

“I-I’m fine. Others might be struggling in different places too…”

Lilith was the one who spoke up bravely.

“Besides, the remaining two Demon Generals might be attacking as well.”

“We should go help.”

“We can’t afford to rest.”

Alice, Luca, and Sarome chimed in.

That said, everyone clearly showed signs of fatigue.

I was the only one still in perfect condition.

Skills generally use mental energy as their source.

So, using them repeatedly can make you feel tired, but I didn’t feel that way now.

My stamina was still high, and I could probably keep using my skills.

Maybe I should head to the other battlefields alone.

I don’t have much offensive power myself.

But if I coordinate with the Rank S and A adventurers on the frontlines──.

Just as I was pondering this.

“Look, the sky…!”

Lilith pointed at the sky in shock.

I and the others looked up.

“Wha…!?”

We gasped in astonishment.

A golden light had ignited at a single point in the sky.

The light spread across the heavens like ripples on water.

The sky was being dyed in a golden radiance──.

Faced with this surreal scene, none of us could utter a word.

The next moment, a violent tremor shook the surroundings.

An earthquake──!?

For a moment, I thought that, but no.

It felt as if space itself was trembling.

The light grew even more intense.

The entire sky seemed to have turned into the sun, a blinding brilliance.

I narrowed my eyes against the glare.

“What is that──?”

Something began to emerge from the golden sky.

Silhouettes resembling humans.

There were about thirty… no, nearly forty of them.

“Angels…?”

I muttered in disbelief.

From a distance, it was hard to gauge their exact size, but they were probably around three meters tall.

They were luminous, pure-white humanoid figures.

The halos floating above their heads and the radiant wings extending from their backs exuded an overwhelming sense of divinity.

“The servants of God, the holy angels…!”

“I’ve only ever seen them in fairy tales…!”

Lilith and Alice groaned.

Those angels turned into meteors of light and scattered in all directions.

Soon after, pillars of light rose from their landing points.

A series of deafening explosions echoed, resonating deep in our guts.

Sounds that suggested intense combat.

“Could they be fighting the demons…?”

I suddenly realized.

“Indeed.”

A voice spoke up close by.

Before I knew it, a glowing silhouette had descended in front of us.

A face shaped like a mask.

Skin as hard as armor.

Wings of light extending from its back and a radiant halo atop its head.

The solemn aura emanating from its entire being naturally evoked a sense of awe.

I could tell instinctively.

What stood before us was a sacred being──.

“We angels are drawn to demons. Regardless of our own will… that is the constraint placed upon us, the holy servants. And──when angels and demons clash, they can only vanish.”

“Vanish…?”

“Prepare yourselves. Soon, the shock of battle will manifest as a catastrophic phenomenon, shaking the world.”

The angel spoke.

“Bearer of Ilfaria’s power. You must protect what you are meant to protect.”

Does it know me…?

“May there be fortune in the world of men.”

With those words, the angel flew away.

In its wake, another pillar of light rose.

Explosions rang out, and the atmosphere trembled.

──Prepare yourselves.

I recalled what the angel had said.

──Immediately after, a tremendous blast swept over us.

Cracks, dozens or even hundreds of them, spread across the ground, tearing it apart.

Massive amounts of debris erupted from the earth as if it were exploding, creating countless craters.

The shockwaves turned into violent winds, raging across the land.

Just how much destructive power was that?

A golden space──[Elysion Gate] had automatically manifested around us, so I, Lilith, and the others were all unharmed.

But what about everyone else──?

※

When the servants of God and the servants of demons──two opposing forces──clash, they cannot avoid mutual annihilation.

Wherever the angels descended, the demon armies were attacking.

The radiant angels and the demons and demon beasts shrouded in dark miasma.

The moment they met, both sides vanished in an instant.

The enormous energy released at the same time became a destructive shockwave that ravaged the entire world.

Pillars of light rose one after another, illuminating the sky in a blinding glow.

Heatwaves and blasts swept across the land, mowing down people and buildings.

It was as if a global cataclysm had occurred.

As if it were signaling the end of the world.

Or perhaps──the beginning of the end.

※

A week later, we returned to the Adonis Kingdom.

The demons’ two large-scale invasions──we had completed the massive quest to repel them.

According to the guild headquarters’ radar, it seemed there would be no third wave of demon attacks.

──And so, everyone was given temporary dismissal orders, and I returned to my hometown, Tyras City.

Lilith, Alice, Luca, and Sarome came with me.

The town looked mostly unchanged.

The streets were as crowded as usual, and the only noticeable differences were a few damaged buildings.

“I’m glad. It seems everyone is safe.”

When we arrived at the guild branch, the receptionist, Jinnette, rushed over to us.

Her serious-looking face, with her black hair tied in a chignon, showed clear signs of exhaustion.

“Is the town okay?”

“Yes, this area was relatively lightly affected. But in some places, entire cities have disappeared, or the terrain itself has changed… The damage seems quite severe.”

Jinnette sighed.

“Count Lafiel is leading the reconstruction efforts. Evacuation, building repairs, and relief supplies are all progressing steadily.”

She gave us a brief rundown of the situation.

Count Lafiel──Lilith and Alice’s father.

“Things have gotten really bad, but I’ll do what I can too.”

“Right. We will as well.”

I nodded at Jinnette’s words.

The destructive phenomenon that erupted when the angels and demons clashed──.

It had swept across the world, bringing with it a single ‘change’.
