The bank itself uses a construction of stacks of gold bullion, and has an alarm system that goes off if even one bar is missing. Fifty tons of gold bullion. If we can't have any missing, then we'll just add on. Shall we go for it? Within a defense net reminiscent of the war, the exchange bullion for bricks operation begins.
