Pledge of Allegiance.

Li Wu comes from a lowly background but due to a misunderstanding, becomes a member of the Imperial Secret Police known as the Embroidered Uniform Guards. On the outside, he appears to be selfish and well-spoken, but deep down he’s honest and treasures brotherhood. Lu Zheng is an original guard; aloof and lacks good speech. But through their meeting, they find the friendship both have been looking for and evolve together. Together, they are pulled into many cases and hatred that runs deep in the court. Will they be able to solve all of the puzzles without becoming targets themselves?
