Coiling Dragon was one of my first webnovels, thankfully. I think if I read it after reading ISSTH, I'd not have enjoyed it half as much. It has plot issues, like a lot of them.
Desolate Era is great but also - bland. The comedic element that ISSTH added to webnovels is completely missing.
Other than cultivating and powering up, there is almost no other dimension to the story. That makes it feel a bit lacking.
Still well worth the read, considering there aren't too many other completely translated novels out there.
