On the night of the wedding, the prince asked me what do you think of the democratic system? The rule of heaven is the rule of kings and ministers, fathers and sons. Can you make gunpowder and cement? I lowered my head. Although I am a doctor of science, but in order to survive, I have to pretend to be stupid. He suddenly hummed: I love you, walk alone in the dark alley. Whoever you love, please don't scare me. The prince let out a sigh of relief, and then threw away the dagger in his hand.
