"Old Patriarch Yu, this is not necessary," Feng Jiu raised her hand and said, "We came here today to find out about the origin and purpose of the eight-trigram mirror. May I ask how much Old Patriarch Yu knows?"
Old Patriarch Yu said, "To be honest, I don't know much about the eight-trigram mirror. My father gave it to me and told me to keep it safe because the Yu clan's descendants couldn't take a blood oath with it."
"But I've tried. This eight-trigram mirror can't accept blood to acknowledge its master," Feng Jiu replied.
"Ah? Can't accept blood?" Old Patriarch Yu was stunned. "That's impossible! That's what my father told me. It can definitely accept a blood oath, although I really don't know the specifics."
Taking a breath, Old Patriarch Yu continued, "Perhaps my father didn't explain clearly before he passed away, but I remember he once said something."
"What did he say?" Xuanyuan Mo Ze asked.
