The Young Palace Master Did Not Recognize Her

Yun Yanli's subordinates did not possess the same tracking abilities that he did. They certainly could not track the breaths of each person in the city, so they couldn't know that the guards in residence had been replaced. 

When the young palace master, Ming Die, received the instructions from Yun Yanli to search his house, Gu Xijiu and the gang had already familiarized themselves with the place. Fortunately for her, she had met the young palace master before, so she could certainly recognize her. But of course, the young palace master did not recognize Gu Xijiu.

During the search, Di Fuyi's body was expected to undergo some serious changes. However, it appeared that he had made a mistake somewhere as he turned out to be fine even after the search was over. Gu Xijiu was rather ecstatic by that fact. Upon checking his pulse, she found that he was even more powerful than before.
