I, Xie Zhixing, am a little-known poor teacher in the capital. Forced by my livelihood, I took on a fatal job - to be a teacher for the seventh prince Xiao Wujin, who is known as the "mad dog". Everyone asserted that I would not live for three days, but with my insight into people's hearts and my understanding of the tactics of the previous dynasty, not only did I not die, but under the fangs of the mad dog, I gradually trained him into a loyal dog who only listened to me. I taught him how to read and write, and I also taught him how to murder and murder; I paved the way for him to ascend to heaven, and I also avenged the tragic death of my former dynasty, the Xie family. Above the court, I am his sharpest sword and strongest shield; in the bedroom, I am his only trust and salvation. When he wore the dragon robe and ruled the world, the world only thought that the new emperor was cruel, but they didn't know that all his gentleness was only given to me, the former teacher.
