Apparently, he was talking to Di Fuyi at the end of their conversation.
However, Di Fuyi did not move, "It's fine, I can tell you. My left pulse is…" He described his pulses, and it was extremely accurate.
Long Siye paused and looked at Di Fuyi from his head to his toes, "You're medical literate?"
Di Fuyi was humble, "Not quite."
In fact, his medical knowledge was even better than Long Siye. However, he did not know anything about modern medicine, and he knew based on Gu Xjiu's action that there was more important modern medical knowledge he should learn. Therefore, he came with some hope that Long Siye could help him.
