I recommend "A Thousand Years in the Door", a historical fiction novel. The main character, Liu Xiaochuan, has obtained a door that allows him to travel back and forth between ancient times and modern times. He pacified the Qiang people in ancient times, conquered the barbarians, usurped the Liang Dynasty, destroyed the Wei Dynasty, and gained power. At the same time, he earned money, earned money, and earned money again in modern times! The plot of this novel is compact and spans through the past and present. It's very interesting! I hope you like this fairy's recommendation. Muah ~😗
