Isekaid 40ish Man Returns, Regressed as a Peerless 17-Year-Old

「Did I get scared of a human……?」

Hades stared at me and clenched his shaking fists.

「That’s instinct when you know what your enemy is capable of.」

「How dare you speak like that to a god! I’ll show you why I’m the god of the underworld!」

Hades chanted a short incantation and a black blur, barely humanoid in shape floated up from the bottom of the sea.

More than a hundred of them can be seen.

And they continuously crawl up from the bottom of the sea. There should be a thousand of them.

「They are ghosts of those who died at the sea. If possessed, they will go mad and die. They are not gigas since physical attack is useless to them!」

As expected of the god of the underworld.

No matter how many people have died at the sea, their ghosts will not wander around.

He must have given them magic power and residual thoughts to materialize them.

It’s a trick that can only be done by someone with tremendous magic power.

The ghost came to me as a swarm.

Strengthened by Hades, they certainly have enough magic power to easily drive an ordinary person insane.

Furthermore, given their spirit body, physical attacks won’t work on them.

Even so—

I concentrated my magic power into my palms, which are clasped together in front of my chest.

As my palms were separated, a ball of magic power was generated.

When the ball of magic power became as big as a person’s head, I held it out in front of me.

「Go!」

Countless rays of light shot out of the magic sphere, piercing each one of the ghosts.

「Ha!」

The ghost disappeared into dust as they were hit by the rays of light.

「Purification magic!? No, you’ve removed my magic power from them! How could a mortal use such advance magic!?」

「I don’t remember saying I’m not good at magic」

「Kuh…..bastard!」

Hades made around 20 magic spheres around him.

Each of them has one attribute such as fire, ice, or lightning.

Each of them has the power to blow away little rocks.

「Let’s see how you can remove these!」

All the magic balls flew toward me.

It’s true that it’s troublesome to disassemble several attribute magics at the same time.

However, that doesn’t mean it’s not possible.

-0-

I held my sword toward the magic sphere and concentrated my magic power on the tip of my sword.

Just before the magic spheres landed, I thrust my sword out and at the same time, released an extremely thick magic power from the tip of my sword.

The blow, which had the attribute of explosion magic, blew away all the magic spheres, vaporized the seawater, and stopped at the edge of the divine domain.

If used without the divine domain, this technique would have had a major impact on earth.

「I-impossible……」

All that remained was Hades, who’s right half of the upper body had been scraped off.

「I still have a two tier higher magic to cast—」

Hades’ body has already begun to regenerate.

At the same time, his already enormous mag power swells more.

「Do you think I’ll just let you do it! I still have to save Yui and the others!」
