After collecting the money, the old man was very efficient in his work. He turned around and locked the small iron gate, quickly walked back to the cement gatehouse to lock the windows, and then led a large black dog. The man and dog led the way in front, "You young folks, tired of the city, love squeezing into this abandoned factory. What's so fascinating about this broken place?" the old man said without turning his head.
"Old man, it looks like you've been at this factory for quite a while?" Yang Xiao tentatively asked.
"I've been here since the factory was established. I used to be a machinist—technical work, much better than those doing physical labor." The old man spoke with a hint of pride.
Having been here since the factory was established was good news. Along the way, Yang Xiao took out a newspaper to compare and finally found the location where the woman in the newspaper had hanged herself.
