Weak youngster comes across something unexpected that increases his strength by leaps. Youngster goes into the wilds to train.
All in all, fairly typical Wuxia. The biggest difference is that he is part of a strong family and that those connections are part of the story and not some after thought. Youngster is also not a complete bastard.
The book is a bit short, but it is a good point for an end.
In the end I enjoyed reading it. Probably good for people who want to try the genre or really like it. Curious how speedy the plot will be in future parts, but that is defintely the weakest point for me with the genre...
