Originally, Xiang Wai and Xiang Weimin were gonna follow their father and grandfather back home but then they both decided to give some personal time to this father and son who were actually willing to sit down and talk to each other after so long.
In the end, Xiang Wai had to use her charm as a granddaughter to find Mu Chenyan's whereabouts from her grandfather.
And that's how these siblings arrived at the secret base where Mu Chenyan was keeping Ruan Meilin. Looking at the building before her, Xiang Wai commented, "This is grand."
"Let's go inside," said Xiang Weimin and took her inside.
The people standing guard at this place might not have known these two siblings before but since they entered the door of Xiang Manor, every single employee of the Xiang family knew about their identities. It was to make sure that no ignorant fool could slight them.
