Father and son Lin Yan and Lin Jianguo accidentally traveled to Bianliang in the Northern Song Dynasty during the third year of Jianlong's reign at the construction site. They had no system blessing, no warehouse nearby, and only a brain of historical knowledge and full strength. At the beginning of the troubled times, people's livelihood was in decline. Lin Yan and his father set up in the capital and made a living by writing and ink. They relied on prophets to overcome the difficulties. Amidst the fireworks in Bianliang, he painted a picture of "Along the River During the Qingming Festival" that was very different from the history books.
