Qiao Cong and Old Mu both had lived in seclusion for many years, they quickly chose an empty mansion to stay after they arrived at Xingluo Island. The mansion was right behind Peng Family's residence.
As the only person who could leave but decided to stay on the island, Peng Wu would definitely attract attention from the forbidden area. However, the most dangerous place is often the safest one. Old Mu said this was called "darkness under the lamp." Moreover, Feng Ming had been in contact with Peng Wu secretly, knowing that Gu Ling had companions who lived nearby. Once elders from the forbidden area came to "care" for her, all she had to do was cry out loud and plead for mercy for her son.
Gu Ling still lived in Sheng Yue's room, and Feng Ming was responsible for the meal delivery. She would bring Gu Ling's meal to Bajiao Pavilion at mealtime, and later the meals were made by Peng Wu herself, often still warm.
