Lady Song thought that Nangong Ye was worried about Nan Feng, so she offered a word of comfort, "Nangong Ye, isn't Nan Feng much better now? You shouldn't worry either. Eating is what's important."
However, Nangong Ye shook his head, "It's not about Nan Feng's injury. I'm just pondering a question. Tell me, is it possible for us to return to the past? For instance, traveling from now to a thousand years ago."
Song Cheng laughed, "Nangong Ye, as a general of Nangong, how can you entertain such bizarre thoughts? How could people possibly return to the past?"
Nangong Ye said again, "Minister Song, you are the most learned. Let me ask you, is the land we live on round? Besides the neighboring countries, are there black and white people far across the oceans? And is the sun just another planet like the moon?"
