Can someone explain the cultivation levels,author says 3 mortal earths 3 heavens 3 xiantian skies,in the chapter we see 0-10 levels then 1 grade ,i dont understand anything,author failed badly at explaining the cultivation levels in the novels.The note at the begining with cultivation levels should contain detailed explanation for reference,but in the first chapters all novels shoul;d have cultivation ranks introduced,author failed badly at it.
