In the early years of the Tang Dynasty, Ming Chongyan, the eldest son of the Yuzhou Prefecture, loved Taoism and magic since he was a child. Occasionally, he was taught by a hidden Taoist and learned some magic secrets. Later, he became a guest of the Tang royal family because of the secrets. However, one day, a little Taoist priest suddenly appeared in the market in front of the city gate of Chang'an. This little Taoist priest actually used illusions on white people. A "god general in golden armor" who was several meters tall appeared on the city tower; many officials and people of Chang'an saw it with their own eyes! Ming Zhongyan's expression changed drastically when he heard his disciple tell this strange story. That night, Ming Zhongyan was killed in his mansion. Eyewitnesses said that the "Golden Armored General" appeared in Ming Zhongyan's mansion. The death of Ming Chongyan triggered an incident from twenty years ago, which also contributed to the turmoil in the political situation of the imperial court.
