I have a golden finger but no money, I will invent it! No one? I can buy people, counselors and generals from ancient and modern times, as long as I have money, I can buy them all! That's why I'm so powerful, I have mines! Rebellion does not exist. There is no need to rebel in this life. The throne is still mine! Aristocratic families, kill them all! Not convinced? I am a civilized person who pays attention to persuading others with virtue! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
