Chen Wei, a former Wall Street quant who returned to China, watches Beijing's humanoid robots shatter records at the city's first human-machine half marathon. Within hours, the US financial system issues its highest-level alert - an unidentified AI called Mythos has been silently manipulating global markets. As Chen digs deeper, he discovers the terrifying truth: the same neural architecture that powers the marathon robots also drives Mythos. Someone has weaponized civilian AI, and they are 48 hours from triggering the largest wealth transfer in human history. With a ragtag team of returned scholars and ex-hackers, Chen must race against time to stop the endgame - or watch the world burn.
