Three years after entering the palace, Chu Yunheng's Jiaofang Palace was so cold that fish could be raised. The imperial concubine stepped on her face every day, and the palace officials secretly extorted money from her. She almost forgot what the emperor looked like. She didn't argue, she would cook sour plum soup in a small stove every day, until the whole yard was filled with the sweet and sour smell. Until that day when the emperor passed by, he accidentally picked it up and took a sip. Things in the harem have changed since then. The imperial concubine threw three vases, and Liu Guiren scolded her for half an hour in the imperial garden. Even the queen mother sent someone to ask about the soup recipe. But Chu Yunheng just smiled and added firewood. No one knew that this bowl of sour plum soup contained the truth about the entire family of Anguo Duke's mansion being wiped out.
