Upon returning home, the rich second generation, Zhang Cun, speaks disrespectfully to his father, Zhang Zhenghe. After being corrected on his address, he curiously asks about the origin of the 300,000 bank draft his father received when he first started his business. Zhang Zhenghe proudly recalls that this money came from his "big brother" at the time – Mr. Li, a renowned figure on Wall Street known as the "God of Finance." When Zhang Cun confirms the benefactor's surname is Li, he connects this to a security guard he had a conflict with and tentatively asks if this "big brother" might be working as a security guard, only to be vehemently denied by his father. Zhang Cun then concludes that the security guard has been deceiving him and secretly vows revenge.
