Overhearing the Court, I Become the Empress

Reincarnated as a puppet emperor disguised as a man with less than a year to live? Whatever, I'm planning to escape! But who told me the entire court can hear my inner thoughts?! This throne hurts my butt! The treasury is already empty! A massive earthquake strikes Luoyang in three days! In a year, the Yan Kingdom destroys Zhou, and we all perish! On the throne, the Prime Minister accidentally drops his tablet, and the Minister of Revenue kneels in terror. Every prophecy comes true, and the officials panic. The Emperor cannot leave! If you go, what will we do? From a puppet ruler to a founding empress, I just wanted to live off the land, but how did I get forced to become an empress?
