"Yan Shu was very intelligent, perhaps he could find a way.","If he truly comes from the future, knowing his own position in the previous dynasty, would everything he says still be the truth If he reveals some statements to prove this and convince us, wouldn't it mean he could slander anyone he wants at will Then, with the power of decision in his hands, would we believe him or not",“I’m here to teach. There aren’t enough teachers at the village school, are there I was sent by the government to give lessons to the children.”。
