There is one main love interest, a few slight love interests (basically one's who aren't meant to end up with him forever, but for a short while), and a bunch of hook ups.

The bloodline is indeed special, and has a lot to do with future progress in his character. His special Physiques as I said before aren't innate, therefore aren't anything special. Furthermore his technique are reasonably good, but in comparison to others like Feng Jiaying, are not amazing. I'm not trying to nerf or overpower him, but he is a mortal in a mortal realm, and even in his past life he was nothing much. His stuff is good relative to what he experienced .

His current look due to refinement of the bloodline.

No. Only one female lead.
