It was Coiling Dragons that kept me in the CN zone.
But honestly, it was Martial God Asura that brought me into the scene. First of all it's the name, it sounded so bad-ass way back when, and everything was so fresh, I had never read any cultivation stuff before that. It was all shouty-skills stuff from Jap manga. It's all cookie-cutter now, but it was a revelation back then. Cheers!
