How to say this... I think one before said it well, a change of premise. But it's more than this. First of all, yeah, basically there is no use of golden finger after the first half of the novel. In the first 'reincarnation', it's still exciting and we see a lot. The second one actually begins strong with an introduction of a new, different function of the cheat, but it disappears right after the introduction. Several other things happen similarly: a cool function is shown, not used. A possibility is given, not explored. It feels like the author gave up a lot of things midway to the second reincarnation. From the third one, it is a lot of disappointment, but to be honest, the exictement of new things put this off. In my mind, I always had 'well, prob time is running and author just skipped irl arc to explain later', but no, nothing like this. Fourth reincarnation is a whole bunch of disappointment, and from here on you will always think 'he should use his power now...' and it doesn't happen. I'm not sure why, but the author decided to stop using the cheat and just made it into a system that shows stats now and then (the system panel is horrible and although author improved it, it's still bad and you don't really know many things, he also ruined it further after the change). Basically, he gave up the premise of the cheat wholly, only kept the reincarnting thing, and from the third reincarnation henceforth, it's only a bunch of coincidental and lucky moments. Especially fourth reincarnation, you will see inexplicably many times how easy the author made it for the mc, and it also quickly shows that the pace at which the author went was too high, making many things that happened unreasonable. Also, a huge number of females in the novel are shows, but none of them have any real action and are always passive. Guys are barely present if they don't have a relation to these females. The strong ones are only described as strong to make the MC look better... Finally, he appears dull many times, exhaustingly so.
