The Prehistoric System in the world of Fantasy Novel

In the fantasy world of Terra, society divides into two groups: mana users known as hunters, and those without mana called plainfolk. Lin Fang has been plainfolk since birth. His misfortune deepened when his father died, prompting his mother to remarry and leave him and his sister with their grandmother. After their grandmother's death, his sister moved abroad, leaving Lin Fang alone at sixteen with only a struggling pet shop and his father's unfulfilled dream of success. By his thirties, Lin Fang's life has collapsed. Drowning in debt, betrayed by his unfaithful wife, and addicted to alcohol, he sees no way forward. In desperation, he jumps into a river seeking escape. Instead of death, he awakens seven years in the past with a mysterious Prehistoric system activated by a pendant he has carried since birth. Armed with future knowledge and the power to command prehistoric monsters, Lin Fang now has a chance to rebuild his life and achieve what once seemed impossible: becoming a legendary monster tamer, reclaiming his lost love, and achieving great wealth.
