I was a renowned monster expert in the Empire. I had dedicated my life to the Empire, yet the only thing I received in return was a dismissal and a prison sentence based on a false accusation by my beloved disciple. My reputation and the people’s respect were shattered by the false accusation. I was branded a criminal overnight and imprisoned for three years. And on the day of my release, gates began to reopen across the Empire.
