Resolved It's another transported to anotherworld

Hello, I'm looking for a novel where the Mc is initially sick but then transferred to another world (I'm pretty sure he didn't die for the sickness).What made it interesting to me was that the Mc didn't understand the language of the new world initially and learned martial arts from an old man who doesn't talk much.

 

The only one that I can think is this https://www.novelupdates.com/series/nine-yang-sword-saint/

 

Yeah that's it. Thank you!
