Hey, I was always a big of samurai and even now I am a fan of swordsmen. Because of this I am looking for action novels, where the Mc is s samurai who can be ruthless. And please, no harem if possible. I mean, I had enough of the harem genre in novels/manga/Anime. It is jue5 annoying by now. Thanks beforehand.
Return of the mount Hua sect!! There's a manhua too (currently on hiatus and prepping for a new szn) and that pretty great, the novel is completed. There's also the wandering warrior of wudang, I'm not sure if there's a novel but the manhua is pretty great too. There was another one, I'll have to look for it and come back. These aren't exactly samuri but they're swordsman. I highly recommend the return of munt hua sect if you ever read my recommendations
