Xu Feifei, a legal genius who came out of a small town in northwest China, uses mathematical formulas to deconstruct the evil of human nature. When she discovers that her father's death is intertwined with a transnational money laundering case, a battle for revenge begins with topology as the blade and blockchain as the shield.
Under the champagne tower at a charity dinner, Xu Feifei met Zhou Mubai, an upstart in the business world. His elegant cufflinks hide darknet keys, and the PPT of his charity speech contains money laundering paths. She used probabilistic models to deduce the flow of funds and used game theory to debunk emotional PUA rhetoric. However, during the investigation, she discovered that her mother was actually a key link in Zhou's money laundering chain.
The powerful combination of mathematical geniuses and criminal investigation hackers has torn apart the shady curtain of American justice: 3D printed crime scenes, Bitcoin tracked by quantum computers, real-time data storms staged in the court - when topology meets the Anti-Money Laundering Act, when micro-expression analysis collides with cross-border evidence collection, Xu Feifei uses 21 mathematical theorems to weave a dragnet.
Behind this battle of wits, there are deeper metaphors: the truth about adoption, the shady story of academic fraud, and the ethical dilemma of the AI sentencing system. In the end, she put the titanium alloy calculator left by her father into the blockchain network, allowing justice to exist forever in the form of a 404 error.
Purpose: Use the blade of reason to defeat the evil of human nature
