Originally, according to their plan, she was just an ordinary peasant girl. Even if she was exiled, she wasn't considered an important figure.
Later, she produced heating packs and got someone to present them to the Emperor, who at most would just know of the existence of a girl from the Lu Corporation and the greatest grace would be to acquit her so she could return to Jiangyuan County and continue as a peasant girl.
The people in Jiangyuan County do not know she was exiled, and the exile area is so far from here that there's hardly any interaction.
Such a Lu Shuyu wouldn't attract much attention, and of course, even if she does, isn't there Xiang Weinan? In a little over half a year, the Fifth Prince should be ascending the throne.
With this, Shu Yu shouldn't have much to worry about.
