Lin Yu, an outstanding student at the police academy, was accidentally electrocuted during a simulation exercise, and his soul traveled through the Qing Dynasty and transformed into the frail and cowardly second young master of the Lin family. When he first arrived, he relied on the fighting skills and flexible mind learned in the police academy, and learned ancient martial arts from the nursing home at home, integrating the two to form a unique style.
Encountering bullies on the street who bullied Su Yao, a female performer, Lin Yu took action and met Su Yao and her father Su Dashan. Su Dashan was highly skilled in martial arts, appreciated Lin Yu, and accepted him as his disciple. After that, Lin Yu and Su Yao's relationship warmed up, and they also made friends with heroes in the world. However, the situation in the capital suddenly changed, and Lin Yu's father was framed for corruption by the prince of the court and imprisoned. In order to save his father, Lin Yu teamed up with Su Yao and others, and relied on their investigative capabilities to uncover the prince's conspiracy to seize important military secrets. After obtaining the documents, they were besieged by the prince's men. After a life-and-death battle, they finally broke through the siege and met the emperor. The truth was revealed and Lin's father was avenged.
The days were getting calmer, but Lin Yu did not forget to find the way to modernity. By chance, he learned from ancient books that mysterious power was hidden in ancient ruins, so he embarked on a journey with Su Yao and Su Dashan. In the ruins cave, Lin Yu obtained a mysterious bead, but it also attracted mysterious figures to fight for it. After defeating the mysterious figure, Lin Yu faced a difficult choice: use the power of beads to return to modern times, or stay here to help the world? In the end, he chose to return to modern times, promising to return. When he opened his eyes again, he had returned to the police academy simulation training ground, and that passionate experience in the Qing Dynasty became the most precious memory in his heart, always inspiring him, justice and courage, shining brightly at all times.
