Remember the information Qiu Yuhong found about Ye Xuan earlier, one of the points was that he is very interested in antiques and relics, and he was in this business while at the border.
Marshall claims to have a complete interest chain in the antique trade, mainly focusing on Dragon Country antiques; the Ye Xuan he mentioned could very well be the same Ye Xuan from the Ye Family.
In the United States, it's not illegal for politicians to trade in antiques and relics, but over in Dragon Country, it is illegal.
Especially given Ye Xuan's special status, if he uses his position at the border to transport domestic antiques and relics abroad for profit, that would definitely be a crime with severe penalties.
