In the deep palace, an emperor had not eaten for three days.The Queen Mother was extremely angry about this, and even said indignantly that if she didn't eat, she would starve to death.At this time, Cheng Biyuan stepped forward and promised the Queen Mother that the emperor could eat again.Although the Queen Mother expressed doubts about this, Cheng Biyuan's firmness and determination, as well as the words "If it doesn't succeed, I am willing to pay for it with my life" finally moved the Queen Mother.The Queen Mother ordered her subordinates to supervise her cooking and strictly prohibited her from contact with the Emperor.

Cheng Biyuan carefully prepared various delicacies. The emperor was curious about the change of cooks. After taking the first bite, he was immediately attracted by the wonderful taste.The emperor devoured the delicious food, which also made the eunuch who delivered the meal feel happy.When he saw the words on the eggs, the emperor understood the secret behind the delicious food.

Cheng Biyuan is not only a superb cook, but also tidies up the kitchen diligently.This made the eunuch praise her greatly.She passed the emperor's feedback information to King Qi, and Li Yu'er realized that Cheng Biyuan used vinegar to write on the eggs to convey the message.

News from the emperor asked King Qi to go to Yaowang Valley.Mu Yuan was a little worried about this because Prince Qi's mansion was closely monitored by the Queen Mother's people.Li Yuer had an idea and came up with a clever plan.

As night fell, Li Yu'er and Mu Yuan pretended to be King Qi and Cheng Biyuan and left King Qi's Mansion in a car.Among the supervisors sent by the Queen Mother, one followed and the other ran back to report to the Queen Mother.The real Zhao Fengpan and Cheng Biyuan took the opportunity to leave the house and go to Yaowang Valley.

An old man came up to greet them. It turned out that he was the Duke of Northern Liang, Cheng Wei.When he saw the brocade bag on King Qi's body, he was shocked.Cheng Biyuan explained that he gave it to King Qi.Cheng Wei looked at Cheng Biyuan carefully, from top to bottom, as if he was looking for something.
