I recommend "The Life of a Winner in the City" and its follow-up,"The Life of a Reborn Winner." The story of the protagonist Zhong Yue, who received an extraterrestrial child growth support system, worked hard to earn money, and gradually became a winner in life in the city. Although it wasn't a fantasy novel that fully met the requirements, it still involved extraterrestrial technology and the rebirth of the main character. Moreover, it was a long novel. I hope you like this fairy's recommendation. Muah ~π
