Ermao had worn this pendant since he was very young, but he didn't actually know much about it. He only had this one piece, given to him by his mother, while Wang Bin didn't have one. Ermao only remembered one thing his mother had said, "Wearing it will bless you with ancestral protection."
The problem was, all of Ermao's grandparents from both sides were alive, and although he didn't know his parents' generation well, he knew them somewhat, and then there were people of his own generation. This era didn't place much emphasis on clan affiliations, at least Ermao didn't care about it, but not caring didn't mean Ermao wasn't curious and suspicious now.
When someone is idly troubled or is trying to distract themselves from their worries, even a slight twist can get them excited. Like Ermao at this moment.
