[SPOILER-FREE PART]
I enjoyed watching the first part of the series (I wouldn't call it a masterpiece and it's not even a favorite, but definitely fun!) and I was hoping to see a somewhat worthy conclusion for this story in the second part.
Unfortunately, it looks like everything about the first part that I liked so much was nowhere to be found in the second part. On top of that, the writers somehow managed to worsen the aspects of the drama that were already bad to begin with. At some points while watching I started feeling like they were just making a fool of me.
For these simple reasons, this time around I don't have a list of things that I liked about the drama: the list of the things that I don't like just got horribly long.
[END OF SPOILER-FREE PART]

Starting with the things that were already bad that got even worse:
- The worldbuilding wasn't solid from the get-go, but I was at least hoping that things would stay relatively tame in that regard. Well, I was wrong! This Part 2 managed to produce a new magical artifact and create new magical powers at every turn, all while making the characters completely unable to use their magical means for no reason, all based on what the plot needed from them. The number of times I thought "wait, did that exist all along?!" and "why are you not using your powers/artifact?" might not be infinite, but it's still embarrassingly high.
- While P1 was not rich with fighting scenes, their number was still reasonably high. In P2 there's even less fighting. Also, while the FL used her sword in a couple of instances in P1, here in P2 she barely touches the sheath once and never again. I was looking forward to the rebirth of Naksu and hoping for some badass fights involving her, but I got nothing in the end.
- Introspection doesn't exist, which is amazing considering the amount of time that the characters spend talking about nothing in P2. Most dialogues are just a bunch of poetic lines thrown there for dramatic effect, which only made me feel more alienated. Even Naksu/Bu Yeon wasn't explored at all, which says a lot about how her potential was wasted entirely in the end. Overall, there was a lot of material that the writers could have used from P1, so I can't understand why they chose such a terrible plot for P2.
- I was hoping for the female characters to get better at the very least, but they didn't change for the most part; if they changed it was for the worse. Naksu/Bu Yeon turned from being mature, witty and a little grumpy to being the cardboard cutout of a sheltered princess who whines and pouts whenever things don't go her way: it was painful to watch because her character was actually the most interesting part of the entire series and P2 just ruined it completely. Jin Cho Yeon had the chance to grow from being a plain aspiring wife, but she didn't develop in the least. Heo Yoon Ok turned from being useless to just being annoying. So Yi also had the chance to be more interesting as a character, but her motives revolved entirely around Seo Yul and it got boring very quickly. There's no meaningful bond between women unless it's between a mother and her daughters or just pure hate, which was just sad.
- The love triangles made even less sense in P2. Seriously, WHY?!
- The writers seem not to have learned anything from the ending of P1, because the ending of P2 felt just as rushed and unsatisfying, other than being excessively over the top. I felt like I was watching an Alchemy of Souls parody of some kind.

I wish this was over, but no. The following are the good parts of P1 that were ruined in P2:
- Theme? What theme? This time around the plot is entirely about pointless romance and magic stuff being thrown here and there. If someone could put some fantasy and romance tropes in a blender to make a random plot, this would be the result.
- The dynamic between Bu Yeon and Jang Uk was terrible. Since their master/disciple relationship was nowhere to be found, it really felt like they stayed together all those episodes for the sake of the plot. Her moments with Jang Uk didn't catch my attention at all.
- Bu Yeon/Naksu's personality is nowhere to be found in P2. The fact that she's like that because she lost her memory made sense, but she felt like an entirely different character (a very frustrating and boring one!). The wit and the charm of her character are completely lost here, as well as her mature attitude that made a good contrast with Jang Uk. She turned into a spoiled lady who is obsessed with the idea of eloping for romance and it made me wish she just disappeared from the series for good multiple times.
- Jang Uk's training and rise to the top during P1 made his few fights and adventures very interesting, but in P2 he just became too OP and his fights became very boring. Even the final episodes weren't interesting, because I already knew he would win easily and save the world. The only result was that all the times he conveniently forgot about his powers for the sake of the plot were even more annoying.
- For some reason the props and the special effects looked worse this time around. I also hate how they decided to give Park Jin short hair out of nowhere.

In conclusion, I can't say that I was heartbroken over this (again, Alchemy of Souls isn't even a favorite), but I was definitely disappointed. I can't even recommend watching the series for fun at this point, because this Part 2 just ruined it all.
