Shengtian Gang is a Guest of Fate, presumably a distant cousin of Shi Yun Road, and one of those opportunists living off the big tree that is the Huiming Shi Family. Like Little Pingtou Li Weiping, he was also a henchman for Shi Haowu and others.
With Shi Haowu gone, Shengtian Gang quickly pivoted and latched onto Shi Yun Road, who had just returned to the country, becoming his errand boy.
You might call this path dependence; it's the job he's most skilled at, sudden changes to other work might be uncomfortable for him.
Why doesn't he seek out others? Because others won't take him in! The big shots from the Ancestral Hall are out of his league, while Shi Yun Road is the thickest leg he can currently cling to.
This noon, he went to a western restaurant that Shi Yun Road frequented to eat, even ordering dishes as per Shi Yun Road's pre-set menu.
