Sima Xin (played by Ma Guoming) is a lazy man, and he is very addicted to the Three Kingdoms online game. Because "Zhuge Liang" made him famous in the Three Kingdoms online game world, Sima Xin always regarded the real "Zhuge Liang" as his idol. Because he was falsely accused of possessing drugs, Sima Xin was chased by the police to Longgu Beach. It happened that a super typhoon "Shark" that occurs once every 500 years was gradually approaching Hong Kong, and the twelve zodiac signs were about to be connected in a line. Sima Xin was embarrassed and took a wrong step and fell into the time tunnel... On the other side of the time tunnel, it was the Three Kingdoms era where he was obsessed with fighting day and night. He accidentally came to Wolong Village where Zhuge Liang (played by Raymond Lam) lived in seclusion! During this period, he also met Liu Bei (played by Li Guolin), Zhang Fei (played by Zeng Weiquan) and Zhou Yu (played by Ruco Chan) and other classic characters. Using modern tricks to compete with idols, Sima Xin, who had accomplished nothing in real life, suddenly transformed himself and experienced the familiar scenes of the Three Kingdoms history. Before parting, he had a one-night stand with the palace maid Sang Rou (played by Yang Yi)... Is the gentleman's loyalty, filial piety, benevolence and righteousness or the Hong Kong boy's cunning way to win? A new Three Kingdoms era full of surprises is about to come...
