Wang Enzhu and others rushed to the court to save Zhang Yi, who was executed, and then Zhang Yi described the whole process of restoring gold theft according to the description of the people. They eventually brought the criminals posing as Liu Mo to justice. In order to express the gratitude of the gold theft, the college Meng Shanchang specially approved Zhang Jiaxiong to attend the Taiyi Academy. Zheng Zuyao, a student of the Academy, died on the mountain. A series of strange things made Zhang Yi and others infer that Zheng Yaozu’s death was not suicide.
