Episode 22 recap: Cheng Biyuan helped deliver a message to King Qi.

The Emperor has not eaten anything for three days. The Empress Dowager, in anger, said that if he doesn't eat, let him starve. Cheng Biyuan came in to report and claimed to have a way to make the Emperor eat. The Empress Dowager didn't believe her at all. Cheng Biyuan said that if she fails, she is willing to sacrifice her life. The Empress Dowager ordered her subordinates to supervise Cheng Biyuan in cooking and strictly prohibited her from seeing the Emperor. If the Emperor still refuses to eat, Cheng Biyuan will be executed immediately.

Cheng Biyuan diligently prepared various delicious dishes for the Emperor. When the Emperor saw that there was a new chef, he curiously tasted a bit and immediately became captivated. He ate voraciously the delicious food in front of him, and the eunuch who served the food was also delighted. When the Emperor saw words written on the egg, he understood that there must be something special about the food. Cheng Biyuan diligently cleaned up the kitchen, and the eunuch was happy to see that she not only cooked but also helped with the kitchen chores.

Cheng Biyuan handed the message returned by the Emperor to King Qi. Li Yuer finally realized that Cheng Biyuan was using vinegar to write messages on the eggs. The message from the Emperor instructed King Qi to go to the Valley of the Medicine King. Mu Yuan was a little worried because the Queen Dowager's people had already targeted the residence of King Qi. Li Yuer had an idea. In the evening, Li Yuer and Mu Yuan dressed in the clothes of King Qi and Cheng Biyuan, confidently boarded a carriage, and left.

The person sent by the Empress Dowager to supervise saw this and followed one of them, while the other hurriedly returned to report to the Empress Dowager. The real Zhao Fengpan and Cheng Biyuan later left the mansion and headed to the Valley of the Medicine King. An old man stood up to greet them. He was Cheng Wei, the guardian of Beiliang. When he saw the brocade pouch on King Qi, Cheng Wei was greatly surprised and asked where he got it from. Cheng Biyuan said she gave it to him. Cheng Wei grabbed Cheng Biyuan and carefully examined her from top to bottom.
