I like the concept story of this drama, little bit remind me of Harry Potter. But the plot pace is too slow to the point of boring in the middle of this series. And the ending is... a let down after the long run. Need season 2 or more of this drama.
The casts are likeable, I like Leo Wu and Li Qin, and almost all of the Flame Gang. But in some point, Leo Wu's expression was not match with the situation. His smiley face ruined some of the dramatic moments.
Music is not really impressive, but good enough
Rewatch value... perhaps after they decided to air season 2
Overall, I think 45 episodes are too dragging, perhaps they can finish all this series in addition of 15 episode, no need of season 2, if the plot pace is not too slow in the middle.
