Introduction: The protagonist (graduate student Guan Mu) traveled to the fictional Dayong Dynasty and became a down-and-out scholar Lin Wenxuan. At this time, Lin Wenxuan was impoverished, his parents were dead, he was bullied by his fellow villagers, he was hungry and cold, and even on the verge of death. After Guan Mu traveled through time, he relied on the knowledge reserves and modern thinking of a liberal arts student to first solve the problem of food and clothing, adapt to ancient life, pick up books, and pave the way for the imperial examination. At the same time, he made early connections and avoided early crises.
