Shen Yuan, the legitimate daughter of the Hou Mansion, died tragically and was sacrificed on the rooftop. She was pushed down the steps by her concubine Shen Yan and was given a bowl of poisonous ginseng to kill her. When she opened her eyes again, she returned with her reborn memories and the [Identity Playing Mask System], and she only had three opportunities to become a person.
Outsiders all pity Shen Yan, the weak, stupid and foolish concubine, but Shen Yuan is the only one who understands that there is huge ambition hidden under that innocent skin. Shen Yan secretly colluded with the third prince, secretly trained death warriors, poisoned and framed the prince, planned accidents, and gradually encroached on the Hou Mansion. Even Chu Yuan's life was in her plan.
With the help of the mask, Shen Yuan transformed into a maid and a counselor, sneaked into the enemy camp to intercept secret messages, and used memory to look back and see through all the sinister traps. The heaven-sacrifice trap, the Ci'en Temple assassination, the poisonous soup at the birthday banquet, and the underground secret tunnel of private soldiers, all the layers of Shen Yan's poisonous schemes were revealed.
She teamed up with the loyal dog general Chu Yuan to uncover the three princes behind the scenes and smash the overall conspiracy. When Shen Yan thought she had a chance to win, Shen Yuan took off his mask and revealed all the irrefutable evidence. This revenge with masks as a chess game finally came to an end. She tore up all the hypocrisy, guarded her life, and spent the rest of her life with Chu.
