Well, 'The Traveler's Harem Quest' is also a great one. In this fanfic, the traveler goes through different regions in Teyvat and gradually forms a harem with various characters. It's fun to read as it combines the elements of exploration and relationship - building from the game. The descriptions of the characters are vivid and stay true to their in - game personalities.
Create an engaging plot. Don't just make it about the harem aspect. Maybe the main character is on a quest in Teyvat and along the way, they form relationships with different characters. For instance, they could be searching for a lost artifact and during this journey, the harem starts to form. Also, make sure the interactions between the characters are natural and not forced.
As of now, the Genshin manga is not finished. The story is still evolving and there's more to come for fans to enjoy. The creators are taking their time to develop a rich and engaging narrative.
There's no definite answer yet. It might continue if there's enough demand and the creative team has more story to tell. But it could also stop if they feel they've completed the story arc.
There is a Genshin Impact manga available. It brings the game's world to life on the page with beautiful art and engaging storylines. It's a great companion to the game.
