Review Detail of Spearow0 in Final Boss of the Multiverse

I read a bit after the point that the protag created a race of shota neko immortal space people, don't know if I recommend it or not, I can just say that I stopped reading, in my honest opinion, this is not 1 fanfic, this could have been a collection of different independent fanfics for each complete "Arc" the protagonist had, many of those are 7/10 or even 9/10, some are boring and non sensical like a 2/10 or less, overextending and not knowing when to end is the problem of this fanfic.
