The novel uses the "Silk Road Embroidery Book" handed down by the Lin family as the core clue, telling the story of Lin Wan, the successor of embroidery art, and Zhou Yan, the representative of capital power, working together to launch the "Splendid Return" project. Thousand-year-old embroidery records are scattered along the Silk Road, recording traces of hundreds of lost cultural relics. Lin Wan brought their ancestral restoration skills, while Zhou Yan used capital and technology as their wings. Starting from Pingjiang Road in Suzhou, they traveled across Rome, Samarkand, Dunhuang and other places. In the process of pursuing the fragments of embroidery records, they not only had to decipher the civilization code in the embroidery threads and restore national treasures such as the Tang Dynasty "Flying Sky" embroidered flags, but also had to fight against the "shadow" organization that resells cultural relics. The story is intertwined with the inheritance of skills of two generations of restorers, the splendid memory of the Silk Road civilization, and the firm belief in protecting the roots of culture. In the midst of exploration and confrontation, it shows the hardships and glory of cultural relics returning home.
