Rich Family's Substitute Sweetheart - Chapter 23

Kaidan (Kaidan refers to eerie tales of strange, mysterious, rare, or bewitching ghosts and monsters from Japanese folklore.) feed on cognition, wield information as weapons, and use information as currency, existing between the peculiarities of neither life nor death.They exist in human rumors and dwell in the shadows of the world.“Does this mean I will become a Kaidan?”In ancient times, they were worshipped as deities, empowered by faith.“Then I am a deity!”In more recent ancient times, they were regarded as demons and fed on fear.“I will become the master of Kaidan!”However, as the tides of time washed over, they gradually vanished, leaving behind only texts considered to be delusions.“To restore the glory of Kaidan is an undeniable duty of ours.”But you are not yet a Kaidan, hmm, nor a person.“Well, becoming a Kaidan counts as success.”

Mystery is the nourishment that keeps me from being ordinary.

It has been 20 years since he came to a world similar to the modern European background. With his early wisdom, Fei Lin learned a skill and finally became a decent person.

Originally thought that he would marry a wife and have children and live this life in a dull way, but found that there is another world under the shadow of the world.

In that world, there are occultists who practice esoteric techniques and master extraordinary powers.

It is weird to spy on humans in the dark and feed on humans.

There are evil god believers who worship the evil god, please the evil god through bloody sacrifices, and exchange power from the evil god.

There is an evil god who wanders outside the world, peeps at the world, and only infiltrates the power of scales and claws, which is enough to cause people to fall.

With the mystery as nourishment, he is no longer ordinary after 20 years of ordinary.

A man who used to review novels dies in an elevator accident and is sent to the world of Teyvat [Genshin Impact] to live his life the way he wants.

What will happen when an unknown being like him enters the world of Teyvat? Will the Archons hunt him, or will he hunt them instead?

Please support my Patreon for more releases and faster upload. If it goes well I am thinking of quitting my job and focus fully on writing. That would be nice as my job is really annoying.

This story is my first wish fulfillment. It will be a little different from Genshin Impact's story, since the game is updated so often and things are added or changed. Currently it's patch 2.3 and I have been playing the game since it came out. So I am following the story closely, but...

It will not always be the same story. I'll do my best to get as close to the original as possible with my writing skills.

I will primarily focus on adding new things as well.

The romance will be slow, but we will get there.

Smut is out around chapters 120, mostly to develop romance before going into it.

Harem will be expanding, but at a decent rate...

I want to develop the characters first before I undergo another harem expansion.

Adrien’s tale is a thunderous symphony of vengeance, mystery, and ascension. Awakened with no memory but wielding a shadow-forged blade, he traverses a fractured world where gods rule through fear and silence. His forgotten blood burns with the legacy of the Godslayers—beings once feared even by the divine. As he hunts corrupted gods and unearths shards of unimaginable power, Adrien evolves from a wandering enigma to a force capable of defying fate itself. Twisting through betrayal, hidden empires, and awakening legends, his journey is not just one of survival, but of reclaiming divinity to break the sky itself.
