Shen Yan, the general of Dajing Town, was stabbed in the heart by a cold arrow during the battle to destroy the city, and accidentally traveled to the modern society of 2023. Falling from the iron-blooded battlefield into the prosperous city, he brought the composure and obsession of an ancient general to face unfamiliar things such as cars, mobile phones, and supermarkets. Under the careful care of the kind girl Lin Wan, he struggled to adapt. While learning modern life skills, he also found the value of survival as a gym martial arts instructor.
By chance, Shen Yan reunited with his lieutenant Qin Feng, who had also traveled through time. In the collision of ancient and modern differences, the two adapted to the modern rhythm while persisting in tracing the truth of time travel. They accidentally discovered ancient symbols on strange stones in the suburbs, which were suspected to be key clues to return to their homeland.
The obsession with family and country responsibilities and the gentle fetters of modern life form a fierce pull. Shen Yan repeatedly struggles with his guilt for the people of Dajing, his growing relationship with Lin Wan, and his comrade-in-arms friendship with Qin Feng. When the clues of time travel gradually become clear, he will finally make a choice between "returning to his hometown" and "sticking to the present", interpreting a period of growth, redemption and emotional choices that span time and space.
