Top Tier Providence, Secretly Cultivate for a Thousand Years顶级气运，悄悄修炼千年

Yeah, nothing much to add. At the end there's just plenty irrelevant side stories no one (including MC and author) cares about, all schemes are basically 'me have the book, me curse rill he dies', all training is basically '1 billion years have passed, he's now stronger'. Was hard to read last bunch of characters, so had to take a lot of pauses. I feel like if this was 2 times shorter, it would have been 20 times better. Remove irrelevant side stories, remove a few realms(for example make Chaos the last boss) and make some scaling mid boss that had something similar to system(but something else) but chose an entirely different path and got lucky. Make so he can actually do something against MC. That way there would be at least 1 relevant side story with action. Make him OP on MC level.
Without that, there's no threat, actions are irrelevant and he's just waiting his way to immortality. The most interesting part was before becoming immortal, or even before that when he actually knew how to walk and meet people who were(at the time) relevant.

Ее у него просто достаточно много чтобы он об этом не заботился тем более что после прорыва он восполняет свою продолжительность жизни одновременно увеличивая ее многократно

His lifespan is refreshed everytime he breaks through a realm. It can be either a major or minor realm. He curses using his origin lifespan and enemies with significantly higher cultivation levels can supress or outright ignore the curse.

Good review, plenty novel related information. Now I know exactly what happens in the novel and exactly why I shouldn't read it....
