Hei Bao seemed confused upon hearing Lin Mu's words. He could not think of anyone that would fit that description and wondered if it was someone that he didn't know of. They had already done their research on Lin Mu and thought that they knew most of the things about them.
In case of friends, Hei Bao knew that Lin Mu did not have any friends left in the town. Many of his childhood friends had left the town over the years and some had even died in the plague. While there were others who chose to leave the town after their family members died.
One of the ones that was still left was Lu Xiao, but even he had become distant over time. Another guess he had that the friend Lin Mu was talking about was perhaps someone from Jing Wei's emporium. There was little they knew about that shop or its owner.
