The deposed prince Chu Yanyu was framed and exiled. After being seriously injured and lame, he pretended to be stupid and lay dormant to save his life. The little palace maid Liyue never leaves him and wins his heart with her resourcefulness and cooking skills. The two led the exiled people to open up the wilderness to survive, and successively resisted secret assassinations, quelled the border plague, and united the border garrison. At the end of the three-year period, Chu Yanyu led his troops to counterattack the capital, finally ascended the throne and named Liyue queen.
