One of the best historical drama when it comes to director vision, fight sequences & the production set design, Ep. 1-27 = it's well written and very enetertaining, Ep. 28-53= deserve high praised indeed from its twist & turns storyline, Ep.54-56= it seems the series want to end so badly its just jump from one sequences to another, very ridiculous.
*A pregnant character in labor fall inside a trap, climb very fast & flew on the floor from the huge explosion... it never mention whether her baby is ok or not.
*ZiSheng got to climb out from the trap but his leg got held by a woman, he didn't kick nor try to get out, he just freeze & the huge explosion explode inside but he's fine not a scratch and he just explain in words? thats just silly.
*After all what happened above, Zisheng still got time to save the third prince on time even though it took so much time when he stuck inside a trap, as we see that Lou Yao search for a doctor (because of his pregnant wife in labor) till night during rain, later he's not to be seen again.

Zhao & Leo were co-star (Zhao as 2nd Female Lead & Leo as 1st Lead) in The Long Ballad (2017) and their kissing scenes with their respective partners wasn't shown at all, maybe because of director decision

Anyway, worth to watch it indeed
