Who is Zhangqiu's fortune teller?

You'd better keep this aloof attitude, this thing is not suitable for further research. Throughout the ages, fortune tellers' fate has been bleak.

I know it's a little late. I have decided to stay out of this matter. Maybe time will make me forget him completely, or study science to make people progress.
