Binhai City, located to the northwest, features a mountain range stretching over a hundred miles that has served since ancient times as the first barrier against iron cavalries of the barbarian tribes from the north.
Now, this place has been transformed into a forest park, with the highest peak reaching over a thousand meters. The terrain is treacherous, valleys crisscross, and the scenery is extremely beautiful.
On the eastern side of the mountain range, there is a stretch of flat land conducive to the movement of troops and supplies, hence it has always been a hotly contested location by military strategists.
The Mass Burial Mound that Li Zhenni mentioned is here. It used to be known as North City Cemetery, but now it has been completely abandoned.
This place is relatively far from the city center and has poor feng shui.
Ordinary families wouldn't bury their dead here; moreover, with its heavy yin qi and ghost sightings, even ghosts dislike this place.
