I've been reading some wuxia tagged with romance, but there isn't much weight to the female characters they just suddenly over time atracted to the mc. So, what are some good adventure and romance.
Transcending Nine heavens. Definitely a harem but I am actually really okay with this. They love and respect each other and the girls actually have substance.
Ze Tian Ji, Sovereign of the Three Realms, Murdering Heaven Edge, Immortal God Emperor. One or more might have harem, but at least the female characters are interesting (so far) and have a reason to like the MC. More importantly, the MC's are not pushovers or jerks. They have their motivations and follow their goals. The one in ZTJ is my personal favorite, he's pretty unique ^^. For romance, as of the most recent chapters, MHE and IGE look rather promising. SotTR has an interesting and consistent plot so far, but no distinct female lead yet (there are some girls, but I don't really care about them, kinda throw-away characters). I'm hoping one will appear later.
Really?... Well even if qi or whatever turned the mc's brain to mush it's still good, the novel that is.
If Xuanhuan is allowed then Heavenly Jewel Change as well as Duolou Dalu and Shen Yin Wang Zuo as stated above.
