MTL - After 10 Years of Chopping Wood, I Am Invincible - Chapter 18 , the case is clueless

One day, a door to another dimension opened all over the world.

“Channel”

At the same time as the channel opens, different races appear on Earth, and mankind awakens its magical talent.

But…? Yoon Min-joon, was able to use magic long before the channel opened.

The forced escape of a reclusive loner who was once the only wizard on Earth.

“It’s dangerous outside the house.”

It all started with a Book review…[To Kill A Demon Lord…] had everything; It had Magic, It had action, it had an abundance of interesting characters and—probably most important of all—it had Vampires.Kevin (Username: Kevin_The_Man) enjoyed the read. Stayed up to date with every chapter update and it quickly became his favorite Webnovel… That was until the Author killed off his favorite character, Caius Von Helsing, A Vampire Spawn who spent most of the story frustratingly resisting his Vampirism so as not to ‘become a Monster’.Kevin quickly wrote a review expressing his dissatisfaction so naturally, when the Author replied and asked for Kevin’s help in making a revised edition of the story, he quickly accepted…… Only to fall asleep and wake up in the world of [To Kill A Demon Lord…] as none other than his favorite character, Caius Von Helsing, the Vampire Spawn.Kevin—now Caius—quickly discovers that there is so much more involved in making a ‘revised edition’ of a novel than simply writing it. And that there are powerful forces that especially want Caius to die and stay dead…… But that death is still quite in the future so Kevin—now Caius—is quickly optimistic.He has a mission now;To enjoy the wonders this world has to offer—as the original character never would—by fully accepting and evolving his nature as a Vampire.

Living things really are ignorant – the greed to obtain the key to knowledge and the fundamentals of energy overpowers them. Little do they know that knowledge is full of lies and energy is the root of destruction. Us, mages, have mastered travelling through space and time. We are invincible, we can turn worlds into dust and you, mere ants, will be wiped out with no trace.

-Mage Adam

An A.I.(Artificial Intelligence) gets reincarnated into a world where he becomes a mage.

A muffled murmur sounded softly,

Crazy goblins ravage the village,

Mutated beasts roam the fields,

The ancient old gods are gradually awakening,

Just when the darkness is about to engulf the entire continent,

A brave man from another world quietly appeared,

This may be the darkest hour before dawn.

Human: “The savior has come?”

Monster: “Have new food arrived?”

Till the fame of the brave spread far and wide,

Walking through every corner of the continent,

He/she/they know,

What is the real darkest hour.

The monsters and humans said in unison:

“I beg you to be human, the ancient gods were so scared that they went back to sleep.”
