Legend has it that after Li Zicheng was defeated at the end of the Ming Dynasty, he left behind a vast treasure worth a fortune. The secret to opening it was entrusted to four of his closest guards, surnamed Hu, Miao, Fan, and Tian. Their descendants spent generations entangled in feuds and affairs of the heart as they sought to uncover the secret. At last, Hu Yidao, heir to the Hu family, and Miao Renfeng, heir to the Miao family, two peerless heroes, faced off in a breathtaking fight to the death. During the duel, they came to admire each other. But Tian Guidao, a descendant of the Tian family, was determined to claim the treasure and resorted to foul play. While Hu Yidao and Miao Renfeng fought, he poisoned Hu Yidao. With his dying breath, Hu Yidao entrusted his newborn son, Hu Fei, to his loyal servant Ping Asi.
