I have only read the first 136 chapters. The novel has great idea and plot is interesting. The big but is that if you remember what author has told you before then it gets annoying when things just change. For example the size of his dantian dropped a lot at one point. First it was able to fit 2000 wisps of qi and then it was 1300. And there have been some other also. But if you can overlook those then this is great novel.
