Old Mo's full name was Mo Xiaoyao, and his cultivation had reached the half-step Heavenly Wheel Realm.

He was an enforcement elder of the Jiang Clan, a Primordial Immortal Clan.

In the middle of the novel, he officially appeared as Jiang Tan'er's "bodyguard."

It made sense; according to the original timeline, how could a half-step Heavenly Wheel Realm expert appear in the capital of the empire for no reason?
