From the trailer, although the styling is similar, the character of Li Yan feels very different from SF especially since Li Yan is based on a historical figure + his actions in the trailer.
I like this style (his personality as a military strategist and a king surrounded by intrigue, who does not trust anyone), and also, despite his fragility (illness and personality), he also has a strong personality (yes , like Si Feng: mixture of strength and vulnerability). But I believe that these characteristics also match this new character.
