I recommend stories that don't cross over with other anime, but are purely about Genshin, Honkai Impact, and Honkai: Star Rail.
Whenever I browse these stories on Jinjiang, they always end up crossing over with Bungo Stray Dogs, Jujutsu Kaisen, and the like (sobbing cat.jpg).
P.S. There may be a few other elements, but not many.
P.P.S. I only recommend completed stories.
Theme: Let me show you my treasured collection.
Okay, finally someone has made a collection, so I can be lazy now
