He was the weakest and even persecuted, but after 100,000 years of training in the super-difficult labyrinth, he becomes too strong and has no enemies - he will be a warrior without any sense of being the strongest because he has lived a long bocce life.

--6433 years since the start of the game

The lightning zone is a hierarchy where lightning strikes incessantly.

If you don't have lightning resistance or higher, you won't even be allowed to walk in the first place, this is a dead zone.

It took me a long time to acquire [Lightning Assimilation], and I started exploring this place for the first time.

Currently, I'm pushing forward through a place that is nothing but rugged rocky mountains and wasteland.

In a rain of thunder, a flaming sword flashes a few thunderbirds that swoop down from behind me and they burst into flames and turn to dust.

Hmmm, this box again: ......

I let out a big sigh at the two metal boxes that sit hidden in the shadows of rocks.

For some reason, this dungeon is filled with seemingly extravagant boxes. The contents of the boxes include various recovery items called potions, useful items and weapons with special powers, but there are also special items inside.

When I tried to open the lid of the metal box with the tip of my flaming sword--

The metal box was squeezed open with the tip of the flaming sword.

The metal box transforms into a giant mouth and attacks me, trying to swallow me.

It's depressing.

Cut off both sides of its mouth under a single blow with the flaming sword.

Yes, this metal box can become a mouth. This metal box can take on the form of a mouth that bites you or a demon that attacks you in the form of a monster. It's a so-called trap, but it's completely ineffective because it doesn't disguise the presence of the demon.

It's a good thing that they're not going to be able to get rid of their presence, because if they want to eat me, they should at least get rid of their presence. This is just unpleasant if it's this blatant.

With a cluck of the tongue, I open another nondescript metal box, which contains a pair of gloves. There was a glove in it.

---------------------

The Glove of the Thunder Beast: Uses atmospheric magic to create and manipulate lightning beasts.

Rank: Advanced

---------------------

A glove that can create a beast of lightning. As a swordsman, I don't see the utility of this armor.

I think I'll just toss this one in the item box.

I'm getting close, and I think the end is nigh.

The hierarchy has been the same for the last 100 years and I've been walking the same landscape. It would have been better if they were all strong, but there are no longer any enemies for me in this hierarchy. I'm getting bored and want to move on to the next level.

Just then, I saw a huge waterfall in the distance. It seemed to be the destination.

It was a cylindrical structure surrounded by a waterfall. In the bottom of the waterfall beneath the cylinder, there were countless things like large fish and reptiles wriggling about. So, you went out of your way to carefully place the enemy at the bottom of the waterfall as well.

Interesting!　What an interesting twist!

As I crossed the rock bridge leading to it with high spirits in my chest, I found a lone, thunder-clad tiger, several meters long, standing majestically on the top surface of the stone column.

Do I have to fight it for now?

"The final test of the upper levels, defeating the [King of Thunder and Tiger], is about to begin.

Sure enough, an inorganic female voice echoes in my head. I'm not sure if this tiger would be my preferred opponent. The only thing I can smell from him is the smell of small fish. I'm sure you'll be intrigued by the fish and reptiles below. I'm not a fan of them. This is a done deal.

The thunder-clad tiger gallops and leaps across the ground toward me. It is about to thrust its sharp fangs into my throat.

"[Kairyu Kenjutsu Itto-ryu], the first kata--the line of death.

At the end of my quiet words, the [Thunder Tiger King] is disintegrated to pieces.

I immediately walk towards the main desh of this time's ordeal.

''Confirming the defeat of 【Thunder Tiger King】--''

I jumped down to the bottom of the waterfall when the usual inchoate female voice, echoing directly into my head, announced the defeat of that tiger.

'Huh?　Huh?　Hey, wait a minute!　You are absolutely crazy!

On the way down, I thought I heard a crazy woman screaming, but that was replaced by my killing intent.

It was a wonderful struggle that made my soul boil. The demons under the waterfall were all overwhelmingly strong, with that [Thunder and Tiger King] not even a problem. After dying many times, when the remaining elixir was the last one, I finally killed all the demons under the waterfall pot.

Now, after recovering from drinking the last elixir, I've just climbed up that column.

''Jeez, the upper level final trial has been cleared. I'm sure you'll be able to see that the Thunder Tiger King has been defeated and the super rare condition has been fulfilled. A special clearing bonus will appear.

In a complete change from the usual emotionless voice, a very domineering female voice echoes in your head, and a long, thin metal box appears in the center of the cylinder.

Ho. It seems that you can get a reward for killing that small fry tiger. After all, it's a small fish, and it wouldn't be much anyway.

When I opened the metal box, I found a weapon in a form I've never seen before.

"Is this a sword?

Maybe it's a sword. Pick it up and shake it, and it blends surprisingly well. I immediately put an appraisal on it.

---------------------

Nihon-Tou, the sword of the otherworld, said to have slashed the thunder or the god of thunder.

Rank: Legendary grade.

---------------------

The otherworldly sword. I feel comfortable with this hand. I have a feeling that this is going to be my new partner. That tiger monster is quite useful for a small fry, isn't it?

After nodding in satisfaction, I sheathed my sword and strapped it to my waist, and started walking to resume my search.
