It's one of the few worthy Kung-Fu and adventure novel/manga series by a Hong Kong author.
As the story begins, there were many clans/schools of Martial Art and weaponry. But the balance among different clans was overturned when the powerful Wudong clan announced that they wanted to be recognized as the Strongest Beneath Heaven (Note: Strongest of the World might be more direct, but it's a bit different from the original Chinese term) How did they plan to manage this? Simple, by challenging other clans, if the other clans refused to surrender, then battles and bloodbath ensured.
Our main characters are a pair of young swordsmen/martial artists, whose clans were both destroyed by Wudong, both swore to seek revenge against their enemies. During their quest, they found unlikely allies and dangerous foes, but most importantly they pushed their limits and learnt more about the true meaning of being powerful.
I like the main characters and their opinions on Martial Art, being a swordsman/martial artists is not only a way of life, but also a philosophy. I like how the main characters later realized there're more things for them to discover about themselves and the world of Martial Arts instead of seeking only for revenge. I especially enjoy how the members of dangerous Wudong clan are not stereotyped into some power-crazy villains.
Last but not least, I also enjoy how the story is not some Good Guys v.s Evil Wudong cliche. The author shows us that different swordsmen/clan masters had different ways to deal with Wudong's challenge, some of them stood their ground and fought, some wanted to duck their heads, some surrendered without even a fight, their different decisions set them apart from one another.
To sum up, it's an enjoyable series, and the author shows his deep understanding on Martial Art, weaponry, and the world of swordsmen in the ancient China. Although I want to complain that from time to time, the characters talk too much like people from the modern era.=_=
