It is a million-word youthful and passionate novel, telling the story of Lin Xingchi, an ordinary female college student on the surface, who fights against fate, protects her family, and gains love as her multiple hidden identities are revealed one by one.
Eighteen-year-old Lin Xingchi was admitted to the History Department of Haishi University. In the eyes of her classmates, she was a taciturn and "transparent person" from a poor family. However, no one knows that this poor student who can't even afford food in the cafeteria is actually "S", one of the top three hackers on the dark web, "Qing Yin", a mysterious guzheng player with over 100 million clicks on Bilibili, "Thirteenth Month", a bounty hunter on the dark web, and a former genius fighting girl.
When his grandmother became seriously ill and needed surgery money, Lin Xingchi had to go back to his old job and repair a surveillance video involving the transnational criminal organization "Net". This move brought her to the attention of Interpol consultant Lu Zhihan and criminal organizations. As the plot progresses, her vests fall off one by one, and a bigger conspiracy gradually emerges - her mother, whom she thought was dead, is inextricably linked to "Luo Wang"; her uncle Lin Guoqiang, whom she has hated for twenty years, is actually a double-faced man who spent his life undercover; her beloved Lu Zhihan's true identity is Experimental Subject 0731 organized by "Father"; and the younger brother Xingxing she has been looking for turns out to be her elder brother, and the biological brother of Zhou Shen, a sacrificial comrade.
The story spans multiple scenes such as university campuses, dark web worlds, underground fighting arenas, and Interpol battlefields. Through Lin Xingchi's growth process from disguise to honesty, from escape to confrontation, from being alone to having a family and lover, it explores the profound meaning behind the "vest".
