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.
