This is surprisingly up my alley. Tbh though I enjoy this type of 'cultivation' esque manhwas/manhuas..it tends to be overwhelming with the amount of information being dumped. Also, if you've read one, you have read all. It is basically the same shit in different format. I do like the master-disciple connection going on, and the sworn brothers bit. The MC faces success after sucess though tribulations come in insignificant forms. Him healing the master happened surprisingly sooner than I expected. I also like that he isn't a douchebag and has a moral compass unlike other MCs. He does struggle between being a doctor and a martial master but he considers himself a doctor first and foremost. He is also incredibly mature and has an objective and logical outlook on life. I didn't see him becoming that attached to his Master but with the context that he was an orphan and all, it does make sense. He wonders if this is what it feels like to have a parent as his master pats his head. Up until now there are no love interest overtly. His friend could be one or that younger sibling of the something clan (sorry I can't keep tabs on everything) . What more? I like the dog
