Wen Nian, a finance master's graduate from a top-tier university, was working late on his thesis in 2024 when he choked to death on his roommate's terrible instant noodles. When he opened his eyes again, he was back in Shanghai in 1994, now a dropout from a no-name college who had just been fired by Wanguo Securities. Armed with thirty years of financial knowledge from the future, he keeps “accidentally” finding himself at the turning points of history: the 327 Treasury bond crisis, the defense of Hong Kong, the lawless early days of commodity futures, the chaos of stock index futures, and battles between cross-border capital. His greatest enemy, business partner, and creditor is Shen Du, a rich young woman who always takes the opposite side at the crucial moment. His greatest “rational temptation” is Su Man, a brilliant woman at a foreign bank who is always smiling, always right, and always ready with a handkerchief. One uses a scarf to wipe away a nosebleed; the other uses a handkerchief. It takes Wen Nian forty-one years to figure out which piece of cloth he really needs.
