This novel is a pretty good read. I have read about 40 chapters and so far the mc is likable and humane. He became sick of fighting after 8 years of constant war and watching his allies die so he wishes to retire, some may say he is running away and abandoning his comrades but i think it is human to have a point where you can no longer live like that(look at war veterans, most will tell you they would never like to see war again). The world building isn't explored in depth but that is normal considering the nature of the story(tower climbing)One tip for the author though: so far the other characters have been enemies of mc(that women called xiayu....) fearfull of mc or neutrall against mc. Make sure that as he ascends to the next floor, there are people on par with the mc, after all there are talented people who picked high affinity elements and are talented by nature so that they can rival the mc even with his experienceOr else you will get a OP mc and that kinda defeats the point of tower climbing but taking a diffrent path than the first time
