Dong Wan, a strong man from ancient times, accidentally traveled through time and possessed the body of a mediocre cook in the modern city who was heavily in debt and betrayed by her boyfriend. She possesses ancient martial arts skills that have been lost for centuries, but she faces many difficulties in modern society. The cold and noble business queen Lin Yue stepped into a street restaurant and became attached to Dong Wan over a bowl of ecstasy noodles and a set of flawless knife skills. However, transnational consortiums and dark forces joined forces to suppress Dong Wan in order to obtain the secret recipe of ancient martial arts. On the one hand, Dong Wan has to deal with the shortcomings in business operation capabilities and survive in the harsh environment of business competition; on the other hand, he has to face Lin Yue's misunderstandings caused by others' misleading and the emotional entanglements caused by his suitors. Transnational consortiums and dark forces are pressing harder and harder, setting a time limit. If Dong Wan cannot respond in time, he will lose business opportunities and ancient martial arts inheritance. In this dilemma, Dong Wan relied on his decisive character to adapt to and utilize the rules of modern society, using ancient martial arts as a sharp edge to overcome obstacles on the road of business and martial arts inheritance, and finally broke oppression, gained love and career, and established his own legend.
