This is my frst review and my english is not god-tier, so I apologize if there is anything that can't be understood.
First of all, I have to say that even though this book doesn't have too much chapters (at least in the moment I am doing this review) I think that have a great history with an MC that is not really OP but has a great Character Design with a strong sense humour sense that makes him singular and memorable. I personally love how he reacts in his mind when he sees Xianxia tropes like an arrogant young master, a jade beauty or a crazy murder MC.
About the history I can't say too much for now (the premise is engaging and the author is doing great things with that). About the World Background, I think that this history presents a logical world and (at least from what I readed) a reality that show us how a Xianxia world is for the people who is not a protagonist in his/her history Xianxia.
I personally recommend this book.
