The Old Duke of Wei is the deceased father of Mo Yunxuan and the former Duke of Wei. He passed away unexpectedly, leading Mo Yunxuan to inherit the title prematurely. He was a respected figure who originally trained the personal guards and managed the Blood Battle Sutra cultivation. His funeral was just held, and his legacy of loyalty from the personal guards and imperial forces remains strong. He is mentioned in memories and in context of the Inheritance test, which Mo Yunxuan bypassed. He is also noted for having expanded personal guards instead of assassins after an assassination attempt.
