Lu Yuan, a graduate student in the history department, traveled through Daqian and became the eldest son of the poor Lu family. His father wanted him to give up his studies and take his uncle's scientific examination, but Lu Yuan flatly refused. In order to ensure his qualifications to study, he vowed to collect fifty taels of silver in three months and use his knowledge from his previous life to make sugar to raise money. From then on, he bucked the trend from a humble family and vowed to make a breakthrough through the imperial examination, fulfill his dream of becoming the number one scholar, and change the fate of his family.
