This is a cross-genre series of sorts, with elements of mystery and zombie apocalypse and even a bit of sci-fi. The premise is rather interesting if a tad bizarre--a cult is scheming something evil. It must be stopped, and ultimately, the main characters must stop them.

The story may not draw viewers in that well if it were not for the interesting characters and their relationships. The dynamics between main characters, Gup De You and Ding Mao, are engaging without being cloying. Each of the four main characters, as well as most of the secondary characters, is interesting in his/her own right, and this is something quite rare.

The story would probably have been better without the obligatory quasi-scientific posturing. The seemingly supernatural occurrences must be scientifically explainable even if the explanations are implausible. This is thanks to China's censorship laws as usual, but I also wonder if there is a subversive mockery of the censorship itself. After all the scientific explanations, portrayed as a Western import, ultimately fail to account for everything.
