Several Problems in Zhu Xian's Works

Zhou Yixian is a descendant of the first generation 13 of Qingyunzi, but he studied the arithmetic and divination of Qingyunzi, never studied magic, and divination is very spiritual. In those days, he calculated the divination for the ghost king, and it was quite accurate. Later, he always let Xiao Huan do the math because of fear, as if his son had been killed by the scourge because of what divination he had calculated ... In short, Zhou Yixian is a master ~ just because he has traveled around the world for so many years and is still alive.
