One night, Emperor Teng Tai Chung dreamed of young man dressing in white who has rescued him from some critical moments. The dream was explained as a good omen. The young man in white was known as SIT YAN KWAI of Lung Mun province in Shanshi. Commander Cheung, who has been assigned by the Emperor to look for Sit, intended to kill Sit instead of bringing him to the capital.

Sit was appointed by his father to collect money from their debtors. Being kind-hearted in nature, Sit gave money to their debtors. Chau Ching, who cheated to earn a living, was requested by Sit's father to cure Sit of his dumbness. Yet Sit became the colleague of Chau in his tricky games. They were caught red-handed in one incident and Sit was shocked to cry out loud and his voice was restored.
