When Chen Tang and Xiao Shuya and others arrived at the gate of the Heavenly Prison, Zhang Changquan was "walking the dog"!
The so-called "walking the dog" obviously wasn't literally walking a dog, after all, Zhang Changquan was a person who really hated dogs, and had killed all the stray dogs within a hundred miles.
Zhang Changquan's version of walking the dog meant using iron chains to drag people confined in the Heavenly Prison out, making them crawl around in the yard, pick up things from the ground to eat, to amuse himself.
Suddenly seeing Xiao Shuya and Xiao Hongchen appear at the gate of the Heavenly Prison, Zhang Changquan was immediately startled, "Holy Maiden, Director Xiao, you..."
Xiao Shuya and Xiao Hongchen, after operating the Gu Sect for so many years, were ostensibly the Holy Maiden and the Director.
Zhang Changquan was taken aback; wasn't today supposed to be Holy Maiden Xiao Shuya's wedding ceremony? And Xiao Hongchen should have been imprisoned by Zhuang Fan!
