Comments of chapter undefined of NTR Rogue in the Apocalypse

in two months he increased his stats /-10 to each stat, despite the fact that he supposedly only focused on increasing strength🤔I don’t know there’s some kind of strange mathematics in this novel; it would be better if the author wrote right away how many points he has added and to what characteristic. Because his opponents had the same characteristics as John now 2 months ago 😖
