My list:
1. Episode 19. Fairy Yuanji: we can make her a nun who is enlightened. Xufeng: what if she really gets enlightened?! A hilarious scene.
2. Same episode, when they all jump through the Wheel of Karma and Fortune. Perfect visualization of, basically, their natal charts, even though this was the circle of trigrams, not Western zodiacal signs. As an astrologer, I forgive the show all of its gaps for this scene and the Fairy's line "a moment's delay can cause 1000 miles of difference in fate".
3. Of all the kissing scenes my favorite is in the episode 21, when he shut her mouth while they were hiding in woods. To be honest, I'm a little dissapointed with Cdrama kissing scenes. They're all underperforming :-)
4. Funny scene in episode 26, after which Night Immortal had "to erase everyone's memory of tonight". Pu Chi- "I defeated Fire Immortal", ha, ha, ha
5. Episode 34, when Xu Feng dies and wakes up as an immortal. It was kind of a silent and the most powerful scene between those two for me.
I know everyone likes their cultivation scene, but it was more funny then sensual for me since the tree shook so explicitly. I was worried about Jin Mi's back :-) And there was a strange moment when both of his hands were pressing against the tree while her robe was slowly being pulled down her shoulder as if he had his third arm underneeth or it might be his servant helping. I laughed like crazy.
They had tons of bright scenes further on, but for me they were like overwhelming. I like something more subtle.
6. Oh, and another one, that sent me goosebumps: the second time when Run Yu showed his true form to Jin Mi. They were sitting on a couch and he reached out for a kiss while releasing his powerful dragon tail. All the kissing scenes are nothing if compared with that :-) Sheer sex
