Han Xiyu, a female special forces instructor, died unexpectedly. Time travels back to the stupid princess Han Xiyu who was poisoned to death by the evil concubine Han Xiyao on her wedding day. The prince married the stupid Han Xiyu to repay Han Xiyu's grandfather for saving her life. (Han Xiyu's grandfather was the genius doctor Gu Langhua, and Han Xiyu's mother died during childbirth.) After waking up, the female instructor beat her concubine Han Xiyao, who pretended to be dead. Finally, the prince punished his concubine Han Xiyu. Xiyu was locked in a room, and later Han Xiyu left a letter of divorce and fled from the palace... Later, when Han Xiyu and the prince met again on the battlefield, there was a rumor that Han Xiyu was hanging out in a bandit's den, and the prince came to suppress the bandits...
