Euri was quite passionate about wanting to become a perfect corporate slave.But after being forced to explore the sentient game infesting his miniscreen, Euri realized that he had stumbled upon an opportunity anyone on the planet would kill for. While the entire human civilization on Planet Nen struggled to deal with the superior lifeforms plaguing the extraterrestrial planes beyond their world, Euri could compete with them all for power by just playing this game!A side-gig that didn’t conflict with his dream of climbing the corporate ladder—how generous can fortune be to bequeath this opportunity to him.Transcending the spatial laws, transcending human notion of cultivation, transcending the rules of Cosmic Development Bureau, Euri began a series of crazy experiments that could perhaps destroy the millennia-spanning schemes of the most advanced civilizations controlling the macrocosm.When interrogated about this fiasco, Euri answered the way a perfect corporate slave should. “Full credit for this goes to my boss, who provided me with the opportunity...”

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.”
