Yan Fei carried out an unthinkable gold heist and then returned to China. However, in the United States, his action had already sent shockwaves through the entire US higher-ups. Nobody had anticipated that, despite such stringent security, someone had managed to steal all the gold stored at the New York Federal Reserve Bank. The heist was incredibly peculiar; no useful clues were left at the scene, leaving the US side without any leads to solving the case.
This sent shivers down the spines of the US higher-ups, as all the gold had gone missing from a heavily guarded underground vault. If the thief so wished, could they not just steal the nuclear bombs from US military bases under everyone's noses? It's worth noting that the defense of these military bases isn't much better than that of the underground vault, and nuclear bombs have far greater destructive power than gold.
