I'll give this drama a 3.5/10.

This is the worst Chinese drama that I have watched this year. There is no thing to like in this drama. I find the story poor written, the transition between the present and the past is too quick. There is no enough story built or even a strange thing happening when the female lead first got in to the past. They just fell in the building and suddenly they are not in the present time. The people in the past didn't even ask them what they are wearing nor find them odd. They just treat them "normal" even it is obvious that they are out of the ordinary. And the fighting scenes are awful. If you look carefully they are just literally spitting the blood out of their mouth (I think it is in the first 3 episodes). Even the effects and the love story between the main leads are terrible too.

Not recommendable and in my opinion this drama will just waste your time so don't bother watching it.
