Western Fantasy: With Thunder in Hand, You Want Me to Be a Hero?

(Fantasy adventure, no System, multiple races, Rumble-Rumble Fruit) After transmigrating to a fantasy world, Luo Wei is hailed as the chosen savior and made the future hero of the Croin Empire. He gets the full VIP treatment and reaches the peak of life, with just one condition: defeat the Demon King and save the world. But Luo Wei only wants to go home, pay the medical bills he borrowed at exorbitant interest for his mother, and let his sister attend school and live a normal life. Most importantly, he needs to repay the loan shark and fulfill his responsibilities as the family’s only son, a son to his parents and a big brother to his sister. Getting home won’t be easy. Even with the top-tier Rumble-Rumble Fruit, he’ll have to develop its power to the limit to stand a chance. To grow as quickly as possible, he’ll work hard on both fronts: the human faction and the nonhuman faction. Note: The Rumble-Rumble Fruit appears rather late.
