There was nothing special about the design of that stone arch. The material was also nothing special. The only thing that evoked special feelings were the objects hanging on the stone arch.
There were three fist-sized "bells" that looked like a bell that could be found in temples. It was just that they were a little smaller and the material used was unique.
The far-right bell was made of stone. A red rope was tied to the end of the bell and it hung quietly at the arch.
The bell in the middle was a bell made of ordinary paper. A gentle breath could sway the paper bell.
Qin Fen couldn't even be sure if the clock on the left was a clock or not. There was no red rope tied to it, and a gentle white smoke drifted out constantly. One could tell that it also had the shape of a bell under careful observation. When they were blown, the smoke would separate.
