Wu Dehui (played by Andy Lau), who works at an advertising company, and his colleague Li Chi (played by Chen Baixiang) went to the mainland for business and smuggled unearthed cultural relics. They accidentally discovered a secret cave, obtained a martial arts secret book, and rescued Princess Yunluo (played by Wang Zuxian) and her maid Xiaoman (played by Mei Xiaohui) from the Yuan Dynasty who were frozen in the cave, but they also accidentally released the evil master Tiancan (played by Yuen Wah). The princess, who was already proficient in multiple languages, was like a duck in water in modern society, and with the help of two ancient women, Ah Hui and Ah Chi also practiced the Buddha Palm and the Seven Rotation Slash respectively, successfully completing the counterattack from loser to hero. But just when the two were in high spirits, Tiancan appeared and vowed to snatch Princess Yunluo away. Once Tiancan chased Ah Chi's home, fortunately he mistakenly recognized Ah Chi's father (played by Cao Dahua) as the hero Long Jianfei, so that Princess Yunluo and Xiaoman successfully escaped, but Ah Hui and Ah Chi were caught by him. With the help of a mainland psychic (Liu Xun), Ah Hui finally mastered the last move of the Tathagata Palm, "Ten Thousand Buddhas Paying Homage to the Emperor", defeated Tian Can and saved the princess's fate.
