That time how not to summon a demon lord

---One week later after the duel---

Grandpa and I had a talk about the seeds of chaos (enhanced species) that were unleashed upon the outside scattered all around the land in an organized manner clearly targeting the food supply distribution.

He had contacted the conspicuous blonde man (Hermes) and had told him about what I have discovered.

He had even boasted to Hermes that he lost to me in a duel.

The other party was first skeptical but still trusted my grandpa's words.

Hermes Familia is said to arrive ten days later.

The journey from city of Orario to our village shouldn't have taken more than two days on a normal phase, but Hermes seems to be a busy guy, and it seems that Orario is still in chaos due to the Evilus remnants.

So, in the meantime I did my preparations.

Before me a purple gate appeared but unlike the gate created by using [Travelers Gate] this gate is completely unseen to the naked eye.

No one besides me only can see or enter the gate.

Stepping inside the gate I waited as the scenery slowly changed.

I found myself inside a well decorated library that seemingly spans for infinity in floors, but most bookshelves are empty, and only the first floor is occupied by books numbering in millions.

Every single book here is an accumulation of information [Genius One] had compiled over the past ten years built in an organized manner from history, magic, theories, science and many more subjects that require my attention.

This is my [Inner Dimension] another innate instinct ability of mine I discovered back in the [Void Dimension] it allows me to enter a private dimension that cannot be invaded.

It's basically a safe zone of sort for me.

Moreover, time inside the [Inner Dimension] moved 100 times slower compared to the outside world, added with its [Limitless] space the place naturally is the best training area one can hope for where I don't need to hold back.

Besides, strangely enough, no matter how much time I spent inside I wouldn't grow biologically in the inside.

This matter is still a mystery for me that needed further study to be understood.

The same goes for inviting another individual to this place.

My purpose on entering my [Inner Dimension] is to summon a servant that will follow my every command.

Even though I cannot invite anyone inside the same cannot be said for summoning someone, but this loophole also has its own limit where only pure spiritual entities without a spiritual body is allowed to inside and the moment they step out they wouldn't be able to go back inside.

After my battle with grandpa I understood that underestimating the people of this world is a bad idea.

However, I can't really help myself from looking down on others.

It's deeply ingrained in my being to act nonchalant and not put others in my eyes unless they were someone important to me or deserve my respect.

Moreover, the fact that I wasn't defeated once in my two lifetimes didn't help either.

Denying my nature is like denying my existence.

So while I cannot avoid or change my nature I will instead go for an alternate route and that is to use every possible advantage I have in order to be always prepared and have a solution ready against any problematic matter that might arise.

Being cautious wouldn't be too bad right?

I pick up one of the most eerie yet hilarious books from the shelves.

The book literally look like a picture book.

It's title…

How not to summon a demon lord?

I developed a deadpan look, wanting to question [Genius One] naming sense.

[Hmph…]

I copied the magic circle drawn on the book recreating it on the floor.

"Come forth demon and be of use to me…"

I called.

The magic circle glowed absorbing my magicules until a two-meter-long figure who has a charcoal like skin with goat features and was standing on its hind legs levitating was before me.

A demon.

I can tell from a single glance.

Its appearance was dazzling and majestic for a creature that embodies evil and terror.

"Compliments on summoning me human boy…"

The summoned demon spoke its voice eerie and prideful, but I can sense the hint of curiosity emanating from it as it look straight at my eyes.

The two of us stayed silent, the demon is probably waiting for me to respond, but I was so engrossed to its beauty that I forget to breathe.

"You can speak?"

I muttered the only words that came to my mind.

I can see the demon looking at me with an annoyed expression, asking as if I'm joking around.

The demon let out a sigh before replying to my words.

"Indeed, I can speak… I'm a greater demon after all…"

It specifically mentioned the title greater demon, trying to remind me of its status and standing.

I did not expect to summon a greater demon on my first try.

Greater demons are powerful demons after all, they can erase a country with ease.

"Do you have a name?"

I asked curiously knowing how important it is to have a name for magical creatures that are bound to the laws created by the Star King Veldanava.

"I'm but a nameless demon…and you?" (Demon)

The demon replied in a dejected manner.

So, it's a nameless demon, no surprise in that…

I'm already lucky enough to summon a greater demon.

"It's Kai…"

I nonchalantly replied.

"What do you need me for, Kai?"

The demon asked me to why I summoned him.

"Well nothing in particular I just need a trustworthy servant and demons are known to follow the contracts even at the cost of their life…"

I honestly answered.

So long one has sufficient power employing demons is the best.

Demon just like monsters respected the strong.

A demon who would betray its contractor is as hard to find as a needle in a haystack.

Except if the contractor is an idiot who did not specify the terms of the contract.

"You… want me a greater demon to serve you… have you lost your mind child…"

The demon began to release a tremendous amount of aura trying to intimidate me but after seeing that it has no effect on me at all the demon stopped.

'What's with this brat? Did he just ignore my aura?'
