I found this drama last year and heard many people gave their positive comments about it. I also know this drama is being recommended by many people. But I still hesitate to watch it because it has a very long episodes and it's a XianXia drama. I prefer Wuxia, rather than XianXia that use so many special effects or magical things, like people can fly, disappear, teleport, a life with monsters, dragons, and so on..of course it doesn't make sense in reality. Even 1 person can be shown as powerful with so many ability.
Surprisingly I finally watch it to answer my curiosity and I regret that I just watch it now! I should watch it earlier!!! Let me give you top 5 reasons why you should watch this drama!
1. The chemistry between main leads (it's a bitter sweet romance yet very romantic). They are successfully describe about true love that willing to sacrifice everything for their love. They are loyal and determined, and there is no annoying third wheel.
2. The plot is very interesting, consistent, details (without loop hole of the story) and you can see the development of the story and each character from time to time. It's totally moving.. I don't even skip any part of this drama because every scene is matter. I never get bored eventhough it's 59 eps!
3. Every character is different and they have their own struggle and unique style. You will love supporting actors too, especially Teng She!
4. The title represent the main issue. It's an adventurous drama with many plot twist! I can say there is no right or wrong in each realm. They have their own good reason to protect their own realm.
5. Amazing drama ost (almost every main actors singing this drama ost and the songs are totally wonderful)

Si Feng's unyielding loyalty and love definitely come at the price of his pain. I understand why so many people call him a blood bag.. LOL.. I’m also in panic he will dead because of losing blood in the drama.. However there is always a good reason behind it. The blood spitting happened when he tried his best to protect his lover, friends and family. Also, there is no scene that make me think.. it’s impossible for him to not spitting his blood.. He always get those big attack!
Also enjoy the same excessive frequency of Male lead Blood-Spitting scene and female lead calling “Si Feng” name in every episode. After I finish the drama, Si Feng name go through my head for days. Thanks to Xuan Ji to make the name is keep ringing in our head. LOL. Xuan Ji is successfuly make us hard to move on from Si Feng. Overall.. I'm gonna miss this drama till the stage I'm gonna re-watch it. Every episode is so meaningful with bitter sweet story!

I wish to see the main leads play as couple again in other drama or season 2. But I'm a bit pessimistic after watch the different connection between Cheng Yi and Bing Yan in reality. They look very shy and affectionate with each other in the press conference and the opening show of this drama, but after getting criticized because of too many skinship, they start to avoid each other and you can see how they are trying to ignore each other in the Closing Show event (drama concert) to avoid further gossip. I feel they are losing their connection in real life because of evil comments from many netizen. Hopefully they can stay professional and still want to working together as couple again in upcoming dramas.
