Gekitotsu no Hexennacht - Volume 1, Prologue: The Time is Third Period

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.”

In my previous life, I was half a move short and ultimately failed to reach the summit. Having traveled back to the past, this time... I want to become the strongest in this world! To become the strongest in this world, one only needs three simple steps: 1. Pick up a newly-transferred Demonic Sect Enchantress off the streets. 2. Subdue and vanquish the demon. 3. Take her cultivation technique for myself. Awesome! I’m already invincible! ———————— Years later, Yan Yu, who had earned the title of “the strongest,” was interviewed on television: Host: To whom do you want to give thanks for your success today? Yan Yu: I’d like to thank a very important woman to me. Host (eyes lighting up): Oh, is she your wise and virtuous wife? Yan Yu: No, consider her a stepping stone, I suppose. Host (wiping sweat): Then... what about the other members of your team? They must have helped you as well, right? Yan Yu: ... How could there possibly be only one stepping stone on the path to godhood?
