Si Lingxi, the last descendant of the Fengdu Si family, holds a judge's pen and is gifted with yin and yang pupils. She just wants to survive in Lingjiang University until she graduates and then lie down and die. Unexpectedly, the gap in the Yin River is about to open, a hundred ghosts walk at night, and the Xuanmen forces are in dispute. Everyone is forcing her to "stand up" - she can only curse and "send away" all kinds of monsters one by one.
