Treasure Venture

During the Ming Dynasty, the Emperor ordered three people to search for a famous country and people management book. The book is hidden in the first Ming emperor’s tomb, together with a large amount of gold. The three people who went into the tomb were the Emperor’s royal brother, Chen Wong Ye, an official, Lu Duan Wen, and his wife.
In order to open the tomb, they need three keys. While in the tomb, Chen Wong Ye wants to kill Lu Duan Wen and his wife to take the treasure and the book as he wants to overthrow his brother and become the emperor himself. Fortunately, Lu Duan Wen and his wife are saved by a grave thief named Li Jia Li, and Chen Wong Ye escapes with one key. Lu Duan Wen and his wife keep one key, while the grave thief keeps the other key.
Together, they propose a pact that their children will get married. On the way home, Lu Duan Wen goes into labour and gives birth to a baby girl with the help of a kind old man named Wu Ma. However, she dies soon after that.
