Lin Shu, the former chief legal counsel of Shenghua Group, was pushed out by her husband Shen Ze and her boss Zhuang Wenyuan seven years ago and was imprisoned for twelve years. After she was released from prison, she opened a bar called "Rust", and everyone thought she was useless. But they didn't know that Lin Shu spent seven years in prison memorizing all 47 pages of the "Tianheng Project" manuscript - the key evidence that could destroy the Shenghua Empire. She began to make plans, weaving a web with intelligence, using memory as a weapon, using her mother as a hostage and herself as bait. When everyone thought she was just a useless chess piece, she blew everyone up with her own hands. But the end point of revenge is that she finds herself living as Zhuang Wenyuan's shadow - every step she pays shakes the bottom line she once stood by.
