Before this.
When people in the surrounding villages died, they would bury their bodies here. At some point, someone passed by here in the middle of the night and saw a " ghost." The news spread, and some bold people who did not believe in evil formed teams to catch the ghost. No matter how many people came, they would disappear without leaving a trace. They reported it to the government, and the county government sent people to investigate. They waited for more than ten days in a row. Not to mention the ghost, they could not even see a figure. There were no other clues, so the matter was left unsettled.
From then on, the people in the vicinity no longer dared to approach. They all took a detour and would rather take a longer route than be tainted by bad luck.
There was a humongous mound in the middle, the largest of the Unmarked Graves.
It looked like a mound on the surface, but there was actually a universe inside.
