My Infinite Cultivation System Novel

Orphan Alex Moriarty is murdered by his sister and transmigrated to a parallel Earth transformed by a dark miasma. Five centuries prior, this cataclysm unleashed unimaginable horrors, mutated creatures, and mythical beings, decimating humanity. Survivors found refuge in the Light Domain, centered around the Tower of Ascension, which, at age fifteen, determines one's cultivation potential. Alex, however, possesses a unique game-like system granting him cultivation before the tower challenge. While others await their awakening, Alex secretly grows in power. Upon reaching fifteen, he ascends the Tower of Ascension higher than anyone in history, reaching the hundredth stair. This achievement unlocks five Eternal Grade talents: Primordial Chaos Physique, Existential Nullity bloodline, Eye of Revelation, and innate cultivation and sword talents. Empowered by these and his Infinity System, which facilitates constant passive cultivation, Alex begins a journey to locate his father and secure Earth for his mother.
