I have read the novel and I wasn't expecting characters and story to be totaly same as novel. But... There is limit to how someone change a story, character structure. You can't just say this anime Desolate Era (The Legend of the Jade Sword) by using same names and some common scene from novel and leaving other things to your own choice. It's literally cheap conterfeit of the story and cheap adaption of that conterfeit. I watched lots of adaption of mangas and novels and I'm a person who respect their work and don't judge them much when ı found differences or other things I
don't like; because it is really hard to give same sensation to watcher when he was reading the same story. People have image characters and event with thier imagination and they might be disappointed when they see the adaption. BUT!!! This is not a situation for THİS adaptation. Sorry for saying this , THIS IS LITERALLY BULLSHJ*T. I even spend a hour to confirm this story is same or has name similarities or author of this story always usses same MC names so that it looks alike. If you want to watch it and if you had already read it before than don't watch it. It would be really hard, you want be able to handle it. If you didn't read it before, you might give it a shot but don't think you know the story of novel. I recommend you to read novel after watching it for two reasons; first, to show you the HUGE difference between anime world structure and novel's world structure of this story. Second, it is really a good novel, it is my personel recommendation. I can't say I read lots of novels but I'm in a level which can differentiate the value of novels. Well... At the you just need to watch a few episodes to understand easly or just the begining 5 min enough for people who read to understand my dissatisfaction.
