"Undercover? You say I am an undercover! I am a noble prince of the blood clan and have countless men under my command. You say I am an undercover agent of the Trial Bureau? Do you believe it yourself, sir? If you dare to slander me again, be careful of my turning against you!" "Sir? Ha! Who asked you to stand and talk to me, kneel down and look up at me!"
