Princess Jiankang could totally have someone copy it in her stead.
Of course, she could also just copy several times and then drag it out.
What he wanted was for this woman, Jiankang, to suffer.
After all, she dared to order that Qiaoqiao be killed. In that case, she could have a taste of it herself first.
Only if Jiankang suffered would Empress Liu feel heartache.
The empress could completely assert that Nanny Li had turned on her master and thus framed her.
That good father of his was not going to depose this empress for this unfounded trivial matter. It would at most be another thorn in his heart.
To depose this empress, he had to first wipe out the Liu Clan's influence, the power deeply intertwined with her clout. This naturally could not be rushed, but it was satisfying to make this damn empress suffer right now too.
