Modern young man Lin Fan travels through time to the Great Jing dynasty and becomes the heir of the Prince of Bingjian. However, his stepmother falsely accuses him, and the prince strips him of his identity, has him flogged, and drives him out of the manor. At his lowest point, he awakens an ancient bronze mirror that allows him to travel between worlds and enter mysterious secret realms, where he obtains rare treasures and masters supreme martial arts. With nowhere else to turn, he joins the despised Embroidered Guard. Using his extraordinary abilities, he repeatedly solves major cases, settles scores with his enemies in the prince's manor, and exposes corrupt officials. Rising from the lowest-ranking guard to greater heights, he remains true to himself, protects the people, and carves out an honorable path of his own as a member of the Embroidered Guard.
