Shang Xiuyuan, a generation of stock god on Wall Street with zero defeats. In his last trade three years ago, his opponent jumped off a building and landed outside his office window. Since then, he quit the martial world, handed over a 370 billion fund company to the state, kept only three gold mines and a black card, and returned to China to become the Gu family's most useless eighth son-in-law. Every day he swipes his black card, buys limited-edition watches, and accompanies his wife to eat grapes. Everyone thought he was a brainless gold-digger recruited by Old Eighth while being blind. Until Pei Lingshuang came knocking with three fake gold mines to force a coup, his identity can no longer be hidden!
