Prince An's childhood sweetheart with the Empress was her most valued confidant, known to everyone in the government and the public. Because of his ability in disaster relief, he became the only minister who could bring a sword to court. The rebellion was frightening to the ministers, but it was a surprise to the empress.
From Prince An's palace, the portraits of the empress he had painted over the years were found.
She was satisfied.
