Everyone in Chang'an knew that she was a rich man named Taishaodong who was bound to lose every bet. He lost money and bankrupted his entire family just to redeem his slaves. He was a top dandy who was heavily in debt and lost nine out of ten games, but he secretly harbored the identity of the prince. In a ridiculous contract, she bets all her family wealth, and he bets the secret seal of the country - whoever feels sorry for the other person first will lose everything. But when 300,000 copper coins rained down in Chang'an, everyone was shocked to realize that this bet was not about money, but about the world.
