Realistic historical action dramas?

the main thing to know is that objectively speaking, the best realistic historical Chinese dramas with a lot of action that are Eng subbed usually depict the Three Kingdoms era. The second most common era is the Warring States period. if you ever feel confused going into them, you can google these eras.

Three Kingdoms 
The Advisors Alliance
Secrets of Three Kingdoms I see you are watching The Crowned Clown, this is also about a puppet emperor
Nirvana in Fire
The Rise of Phoenixes 
The Qin Empire 2 you don't need to watch the first one, it isn't subbed while this one is
Red Cliff movie

If you're ok with semi-realistic, then I recommend Nirvana in Fire.  It's not a fantasy, but it's not completely realistic.
