Genshin Impact : Reincarnated as NPC, Jack a Rookie Adventurer.

The story of a young man that transmigrated as Jack. An NPC in the game called Genshin Impact. A rookie adventurer that sometimes needed player help after being attacked by Hilichurls, a weak monster. In a world full of monsters, treasure hoarders, and of course an organization called Fatui, what can he do? Oh… Thank God at least he got a system familiar with the game he plays. Beware that my English is not my first language, and I don't think I follow the lore correctly since this is fanfiction after all. But I tried my best. Also, I write harem, Just like my name anyway… and my first thought will be most of the Mondstadt Region. Jean, Barbara, Eula, Mona, Sucrose will be part of harem. This fanfiction follows Lumine as a traveller. This novel will be slow-paced and MC weak before becoming stronger. Not immediately, OP. It will be a long journey. If you don't like this kind of story, please leave. I may have written some +18 chapters, but it will be a long way to that chapter.
