The Shen family of the imperial censor was wiped out. Only the legitimate daughter Shen Jinghong fled with the family heirloom jade, and hid in the general's mansion as a maid under the pseudonym "A Ying", waiting for an opportunity to find out the truth. General Lu Chengyuan seemed indifferent, but he paid special attention to her and rescued her in danger several times. As the Yujue accidentally shattered, half of the secret message inside was revealed, pointing to Lu Chengyuan as the mastermind. Just as Shen Jinghong was plotting revenge, a twist suddenly occurred: the other half of the secret letter was in the hands of Lu Chengyuan, and the family's destruction was framed by a traitor. Lu Chengyuan's father was actually a loyal servant of the Shen family, and he sacrificed his life to protect her in exchange for her life. The two cleared up their past feud, worked together to collect secret letters, exposed the conspiracy of the traitor, vindicated the family, and finally stayed together in troubled times.
