In the middle of the night, eager to catch the sacrificial man, Yang Chuxia and Ye Zi'an arrived in town and drove their oxcart into the shop. They then hurriedly went out with Ye Zi'an. Uncle Niu saw the two people looking so rushed and worried that something might be wrong, so he followed them from behind.
Seeing this, Yang Chuxia didn't let him go back, but instead handed her sleeve-arrow to Uncle Niu, "Just pull this when you need to use it later."
Hearing this, Uncle Niu knew that something was really going on and a sense of concern immediately rose in his heart, thinking that he must protect the two kids later on.
That sacrificial man was indeed a master of hiding. According to the confessions of those people, he was hiding in an abandoned house on North Street.
