"Thank you, My Queen." Han Sen's eyes felt wet. She had been really helpful, and even given a precious gift to her enemy.
Han Sen thought that if she found out he was Dollar, she'd be so angry that she'd most likely stroke out and die.
Seeing Han Sen look so grateful, she misunderstood. Her attitude softened, and she went on to say, "If you heed what I say and take me for your proper teacher, you will become a Duke in three years. With some luck, there is a chance you might one day become a King."
But as for Han Sen's current condition, Queen didn't say much. And the only reason she said three years was due to the instability of Han Sen's body. Otherwise, it would not have taken that long.
