Why did Zhou Yixian let Zhang Xiaofan take the reincarnation plate?

Because Zhang Xiaofan is one of the four great monks. Zhou Yixian and Zhang Xiaofan are two characters in Zhu Xian, a novel by contemporary writer Ding Xiao. The novel tells the growth experience of Zhang Xiaofan, an ordinary teenager under the Qingyun Mountain, and the sad love story with two strange girls. By 10, 15, at the end of 2002, according to Zhu Xian's profile, Zhou Yixian knew that Zhang Xiaofan was one of the four great monks in the novel, and only the four great monks could hold the roulette wheel, so Zhang Xiaofan was asked to hold the roulette wheel because he was one of the four great monks.
